ObjectiveTo determine the association between pubertal stage, sex and behavioural profile across and within neurodevelopmental disorders (NDDs) compared with typically developing (TD) youth.MethodsThis was a cross-sectional study from the Province of Ontario Neurodevelopmental Disorders network, including children/youth with various NDDs and TD controls. Caregivers completed the Child Behavior Checklist (CBCL). Participants were grouped into three puberty stages: prepuberty (Tanner stage 1), early puberty (Tanner stages 2–3) and late puberty (Tanner stages 4–5). The association between pubertal stage and CBCL scores was assessed controlling for sex and diagnosis.ResultsThe analysis included 1043 participants (male=733; 70.3%). A three-way interaction between pubertal status, sex and diagnosis was not significant for internalising or externalising behaviour. Diagnosis was significantly associated with CBCL scores for both internalising (p<0.0001) and externalising (p<0.0001) behaviours, with lower scores for TD children than for NDD groups. Late pubertal females showed higher levels of internalising behaviour compared with prepubertal females (p=0.001); males showed no differences. Early pubertal males showed lower levels of externalising behaviour compared with prepubertal males (p=0.01); early pubertal females trended towards higher levels compared with prepubertal females (p=0.051).ConclusionsInternalising/externalising patterns of behaviours across pubertal stages did not differ based on diagnosis. Pubertal females are at higher risk for internalising behaviours.

BackgroundDifferences in genetic influences on disordered eating are present across puberty in girls. Heritability is 0% before puberty, but over 50% during and after puberty. Emerging data suggest that these developmental differences may be due to pubertal increases in ovarian hormones. However, a critical piece of evidence is lacking, namely, knowledge of genetic influences on disordered eating across puberty in boys. Boys do not experience increases in ovarian hormones during puberty. Thus, if pubertal increases in genetic effects are present in boys, then factors in addition to ovarian hormones may drive increases in heritability in girls. The current study was the first to examine this possibility in a sample of 1006 male and female twins from the Michigan State University Twin Registry.MethodDisordered eating was assessed with the Minnesota Eating Behavior Survey. Pubertal development was assessed with the Pubertal Development Scale.ResultsNo significant differences in genetic influences on disordered eating were observed in males across any developmental stage. Heritability was 51% in boys during pre-puberty, puberty and young adulthood. By contrast, in girls, genetic factors accounted for 0% of the variance in pre-puberty, but 51% of the variance during puberty and beyond. Sex differences in genetic effects were only significant during pre-puberty, as the best-fitting models constrained heritability to be equal across all males, pubertal females and young adult females.ConclusionsThe results highlight sex-specific effects of puberty on genetic risk for disordered eating and provide indirect evidence of a role for ovarian hormones and/or other female-specific factors.

Full textAbstract:
ABSTRACT Precocious puberty in girls has endocrinological as well as behavioral implications. We present data from a first systematic controlled follow-up study of 16 adolescent girls with a history of idiopathic precocious puberty (IPP) compared to closely pairmatched adolescent control subjects of comparable pubertal status and normal pubertal history. Findings in four areas of behavior are reported: (1) Psychiatric sequelae: the IPP sample showed an increase in minor psychopathological symptoms. (2) Psychosexual development: The IPP sample was advanced in sociosexual milestones, albeit mostly within the normal range for adolescents. (3) Intelligence: IQ was not different from controls. However, school achievement was accelerated during childhood. (4) Cognitive pattern: The IPP sample had lower spatial perception scores than controls.

Full textAbstract:
BackgroundTestosterone may be a biological factor that protects males against eating disorders. Elevated prenatal testosterone exposure is linked to lower levels of disordered eating symptoms, but effects emerge only after mid-puberty. Whether circulating levels of testosterone account for decreased risk for disordered eating in boys after mid-puberty is currently unknown; however, animal data support this possibility. In rodents, prenatal testosterone's masculinizing effects on sex-differentiated behaviors emerge during puberty when circulating levels of testosterone increase and ‘activate’ the expression of masculinized phenotypes. This study investigated whether higher levels of circulating testosterone predict lower levels of disordered eating symptoms in adolescent boys, and in particular whether effects are associated with advancing pubertal maturation.MethodParticipants were 213 male twins from the Michigan State University Twin Registry. The Minnesota Eating Behavior Survey and Eating Disorder Examination Questionnaire assessed several disordered eating symptoms. The Pubertal Development Scale assessed pubertal status. Afternoon saliva samples were assayed for testosterone using enzyme immunoassays.ResultsConsistent with animal data, higher levels of circulating testosterone predicted lower levels of disordered eating symptoms in adolescent boys and effects emerged with advancing puberty. Results were not accounted for by several important covariates, including age, adiposity, or mood/anxiety symptoms.ConclusionsFindings suggest that elevated circulating testosterone may be protective and underlie decreased risk for eating pathology in males during/after puberty, whereas lower levels of testosterone may increase risk and explain why some, albeit relatively few, males develop eating disorders.

Full textAbstract:
AbstractWe examined puberty-specific effects on affect-related behavior and on the psychophysiology of defensive and appetitive motivation while controlling for age. Adolescents (N = 94, ages = 12 and 13 years) viewed 75 pictures (International Affective Picture System: pleasant, neutral, and aversive) while listening to auditory probes. Startle response and postauricular (PA) reflex were collected as measures of defensive and appetitive motivation, respectively. Pubertal status and measures of anxiety/stress reaction and sensation/thrill seeking were obtained. Mid-/late pubertal adolescents showed enhanced startle amplitude across all picture valences. A Puberty × Valence interaction revealed that mid-/late pubertal adolescents showed appetitive potentiation of the PA, whereas pre-/early pubertal adolescents showed no modulation of the PA reflex. Mid-/late pubertal adolescents also scored significantly higher on measures of sensation/thrill seeking than did their pre-/early pubertal peers and puberty moderated the association between psychophysiology and behavioral measures, suggesting that it plays a role in reorganizing defensive and appetitive motivational systems.

Kata Kunci: Menjaga diri., Pubertas, Perubahan diri, Abstract Puberty or puberty is part of human development. This period is a period of change or transition from childhood to adulthood, where a child experiences physical changes, attitudes or behavior, and maturation of the reproductive organs. Generally begins at the age of 10-13 years and ends at the age of 18-22 years. This period is a vulnerable period for children who are not equipped with knowledge about puberty, self-care behavior and ethics in dealing with this transitional period. The purpose of this community service is that children can control and take care of themselves during puberty by providing insights about changes in themselves. Submission of material provided using LCD media, flipcharts and questions and answers. The end result of this dedication is that children gain increased knowledge about changes in themselves and high awareness of how to take care of themselves during puberty (100%). Therefore it is important to create an innovation program to optimize child health services during puberty. It is hoped that this health promotion program will continue to form a generation of quality youth. Keywords: Take care of yourself. Puberty, Change yourself.

AbstractPubertal timing matters for psychological development. Early maturation in girls is linked to risk for depression and externalizing problems in adolescence and possibly adulthood, and early and late maturation in boys are linked to depression. It is unclear whether pubertal timing uniquely predicts problems; it might instead mediate the continuity of behavior problems from childhood to adolescence or create psychological risk specifically in youth with existing problems, thus moderating the link. We investigated these issues in 534 girls and 550 boys, measuring pubertal timing by a logistic model fit to annual self-report measures of development and, in girls, age at menarche. Prepuberty internalizing and externalizing behavior problems were reported by parents. Adolescent behavior problems were reported by parents and youth. As expected, behavior problems were moderately stable. Pubertal timing was not predicted by childhood problems, so it did not mediate the continuity of behavior problems from childhood to adolescence. Pubertal timing did not moderate links between early and later problems for girls. For boys, early maturation accentuated the link between childhood problems and adolescent substance use. Overall, the replicated links between puberty and behavior problems appear to reflect the unique effects of puberty and child behavior problems on the development of adolescent behavior problems.

Full textAbstract:
Puberty is a critical phase of growth and development characterized by a complex process regulated by the neuroendocrine system. Precocious puberty (PP) is defined as the appearance of physical and hormonal signs of pubertal development at an earlier age than is considered normal. The timing of puberty has important public health, clinical, and social implications. In fact, it is crucial in psychological and physical development and can impact future health. Nutritional status is considered as one of the most important factors modulating pubertal development. This narrative review presents an overview on the role of nutritional factors as determinants of the timing of sexual maturation, focusing on early-life and childhood nutrition. As reported, breast milk seems to have an important protective role against early puberty onset, mainly due to its positive influence on infant growth rate and childhood overweight prevention. The energy imbalance, macro/micronutrient food content, and dietary patterns may modulate the premature activation of the hypothalamic–pituitary–gonadal axis, inducing precocious activation of puberty. An increase in knowledge on the mechanism whereby nutrients may influence puberty will be useful in providing adequate nutritional recommendations to prevent PP and related complications.

Full textAbstract:
AbstractMegan Gunnar's pubertal stress recalibration hypothesis was supported in a recent study of previously institutionalized (PI) youth such that increases in pubertal stage were associated with increases in cortisol stress reactivity. This work provides evidence that puberty may open up a window of recalibration for PI youth, resulting in a shift from a blunted to a more typical cortisol stress response. Using the same sample (N = 132), the current study aimed to elucidate whether increases in cortisol are associated with increases in adaptive functioning or whether they further underlie potential links to developmental psychopathology. Specifically, we examined the bidirectional associations between cortisol stress reactivity and both internalizing and externalizing symptoms across three timepoints during the pubertal period. Youth reported on their own internalizing symptoms and parents reported on youths’ externalizing symptoms. Cortisol reactivity was assessed during the Trier social stress test. Analyses revealed no associations between cortisol reactivity and externalizing symptoms across puberty for PI youth. However, longitudinal bidirectional associations did emerge for internalizing symptoms such that increases in cortisol reactivity predicted increases in internalizing symptoms and increases in internalizing symptoms predicted increases in cortisol reactivity. Findings suggest that recalibrating to more normative levels of cortisol reactivity may not always be associated with adaptive outcomes for PI youth.

Abstract Background: Adolescence is a critical period and is associated with physical and psycho-social changes induced by puberty, which builds personality, behavior, and future health of the adolescents. This study aimed to determine the adolescent’s knowledge and attitude toward pubertal health and his/her socio-demographic predictors. Methods: This cross-sectional study was performed on 1017 adolescent girls who were in the second and third grades of secondary schools in Tabriz, Iran, in 2013. The sampling method was random. The general linear model was used to determine the social-demographic predictors of the adolescent’s knowledge and attitude about pubertal health. Results: The mean (standard deviation) score of knowledge and attitude was 53.2 (13.7) and 66.7 (11.5), respectively (from an attainable score range of 0–100). The variables of educational level, economic status, household members, obtaining information about the puberty, and age of menarche were predictors of knowledge. Educational level, the most feeling at menarche, and source of the most information about puberty were predictors of attitude (p<0.05). Conclusion: The findings of this study show that the knowledge and attitude of adolescents about pubertal health are moderate. Thus, it is necessary to educate the girls about pubertal health to enable them to have a healthy reproductive life in the future.

Aim of study: To evaluate the effect of different feeding levels on body weight changes, sexual behavior activities, and spermatogenesis characteristics of testis tissue in immature Iranian breed lambs.
 Area of study: University of Tabriz, Iran.
 Material and methods: A total of 40 (start of experiment, 4; after 6 months, 12; 9 months, 12; sexual behavior, 12) two-month-old immature ram lambs were divided into three equal groups and were fed for eight months with three different concentrate mixtures formulated using conventional ingredients based on barley grain. Lambs received the same amount of crude protein with three levels of energy. The diet of the low-energy (LE) group had an energy of 10% lower than the control group, which received a diet with optimum energy of 100% according to the NRC. Lambs in the high-energy (HE) group were fed diets with an energy of 10% higher than the optimum energy group. In each group, four lambs were castrated in three steps, including the ages of 2 (start of treatment), 6, and 9 months. Body weight and scrotal circumference were recorded monthly. Sexual behaviors toward estrus ewes were evaluated for 30 min, and the testes were analyzed histologically.
 Main results: The lambs in the LE group had lower body weight and smaller scrotal circumference than HE group (p<0.05). Sexual behaviors in the HE group occurred at an earlier age, such as mount and mounts with ejaculation, as the external presentations of puberty (p<0.05). 
 Research highlights: Underfeeding of pre-pubertal animals delayed puberty, while high-plane feeding advanced puberty.

Full textAbstract:
Previous studies have reported a shift in the timing of sleep during adolescence toward a later time. To date, it is unclear whether hormonal changes during puberty might contribute to this change in sleeping behavior. We systematically assessed pubertal development and sleep timing in a cross-sectional case-control study in girls with precocious (n = 42) and boys with delayed pubertal development (n = 19). We used the Munich ChronoType Questionnaire and the Children’s ChronoType Questionnaire to assess sleep timing in patients and age- and sex-matched controls (n = 309) and used the midpoint of sleep on free days, corrected for potential sleep debt accumulated during the school week, as a marker for sleep timing. Compared to the controls, girls with central precocious puberty showed a delay in sleep timing of 54 min, and girls with premature pubarche slept on average 30 min later. Male adolescents with delayed pubertal development showed an average sleep midpoint that was 40 min earlier compared to the control group. The results of this pilot study suggest an association between pubertal onset and shifts in sleep timing, which is a novel finding in human sleep behavior. Prospective studies in larger cohorts will be needed to examine the robustness and generalizability of the findings.

AbstractContinuous social isolation (SI) from an early developmental stage may have different effects in youth and adulthood. Moreover, SI is reported to impair neuronal plasticity. In this study, we used post-weaning rats to compare the impact of continuous SI on depressive-like, anxiety-related, and fear-related behaviors and neuronal plasticity in puberty and adulthood. Furthermore, we assessed the effect of lithium on behavioral changes and neuronal plasticity. Continuous SI after weaning induced depressive-like behaviors in puberty; however, in adulthood, depressive-like and anxiety-related behaviors did not increase, but—paradoxically—decreased in comparison with the controls. The decreased expression of neuronal plasticity-related proteins in the hippocampus in puberty was more prominent in the prefrontal cortex and hippocampus in adulthood. In contrast, SI after weaning tended to decrease fear-related behaviors in puberty, a decrease which was more prominent in adulthood with increased neuronal plasticity-related protein expression in the amygdala. Lithium administration over the last 14 days of the SI-induced period removed the behavioral and expression changes of neuronal plasticity-related proteins observed in puberty and adulthood. Our findings suggest that the extension of the duration of SI from an early developmental stage does not simply worsen depressive-like behaviors; rather, it induces a behavior linked to neuronal plasticity damage. Lithium may improve behavioral changes in puberty and adulthood by reversing damage to neuronal plasticity. The mechanisms underlying the depressive-like and anxiety-related behaviors may differ from those underlying fear-related behaviors.

In recent years, the existing relationship between excess overweight and central precocious puberty (CPP) has been reported, especially in girls. Different nutritional choices have been associated with different patterns of puberty. In particular, the involvement of altered biochemical and neuroendocrine pathways and a proinflammatory status has been described in connection with a high-fat diet (HFD). In this narrative review, we present an overview on the relationship between obesity and precocious pubertal development, focusing on the role of HFDs as a contributor to activating the hypothalamus–pituitary–gonadal axis. Although evidence is scarce and studies limited, especially in the paediatric field, the harm of HFDs on PP is a relevant problem that cannot be ignored. Increased knowledge about HFD effects will be useful in developing strategies preventing precocious puberty in children with obesity. Promoting HFD-avoiding behavior may be useful in preserving children’s physiological development and protecting reproductive health. Controlling HFDs may represent a target for policy action to improve global health.

Background: National surveys show that lack of Indonesian adolescents' knowledge regarding puberty, whereas menarche onset at the age of 9 years. 
 Objective: This study aims to identify the puberty knowledge of elementary school students with gender-based analysis. 
 Method: The method used is an online survey and analysis using an independent T-test equipped with item knowledge analysis. The samples taken were 221 elementary school students throughout Indonesia. 
 Result: The knowledge of female students was significantly higher than that of male students. While the One-way ANOVA test shows that the difference in knowledge based on level/class is not significant, however, if first-year students’ data is ignored, it can be seen that the higher the level, the higher the students' knowledge. 
 Conclusion: Knowledge of puberty is important as a fundamental for abstinence as a behavior to prevent adolescent reproductive health problems, including HIV and other Sexually Transmitted Infections. Massive, measurable, and planned interventions need to be carried out on an ongoing basis to be able to increase the knowledge of elementary school students regarding puberty. 
 Keywords: puberty, knowledge, students, elementary school

Teenagers, who are studying at Junior High Schools, are in their puberty. In general, teenagers undergo various problems and difficulties in adjusting themselves to their environment in their puberty. The objective of the research was to find out the correlation between family support and female teenagers behavior in their physical change in their puberty at SMP Negeri 1 Deli Tua tahun 2020. The research used an analytic method with cross sectional design. It was conducted in September 2014 to February 2015. The population was 137 grade VII female students of SMP Negeri 1 Deli Tua tahun 2020and 68 of them were used as the samples. The data were analyzed by using chi square test and multiple logistic regression analysis. The result of the research showed that there was the correlation of emotional (p=0.004), information support (p=0.000), and instrumental support (p=0.002) with the behavior (knowledge, attitude, and action) of female teenagers in their puberty. The variable of information support had the most dominant correlation with the female teenagers behavior at Exp (B) of 5.591. It is recommended that the management of the school provide more knowledge and information about the puberty period for their students, especially female students by upgrading them periodically in the knowledge of reproduction health. It is also recommended that parents discuss with their daughters about the change toward puberty and guide them in digging up information about puberty without any fear so that they can be familiar in their daily activities.

Full textAbstract:
The study presents the identification and study of the characteristics of the formation and dynamics of various forms of deviant behavior in the clinic of neurosis-like states of residual-organic genesis, that is guided by the principles not previously used in the study of the studied pathology. Behavioral disorders were studied in a comparative aspect in two clinical variants, which are asthenohyperdynamic and astheno-adynamic manifestations of the cerebrastenic syndrome, which is a part of the structure of a neurosis-like state. The age dynamics of behavioral disorders was studied at different stages of ontogenesis, including childhood, prepubertal and puberty, by comparing the obtained data labeled by the subheadings "Period of the first age crisis", "Period of the second age crisis" and "Puberty period". The study found that age response forms reflect the low personal resources of adolescents and the massiveness of negative social influences. As the analysis of clinical material has shown, during puberty, violations in the sphere of cravings became more distinct. Disorders in the sphere of inclinations at this age are closely correlated with the features of the somato-endocrine metamorphosis and with the unfavorable influence of socio-psychological factors. Lack of sexual desire was in direct proportion with a pronounced delay in puberty. Violations in the sphere of sexual desire, reflecting the nondifferentiation of the sexual attitudes of adolescents with delayed puberty, were characteristic of those studied with pronounced volitional immaturity, in particular with such signs as suggestibility, a tendency to imitation. During puberty, the clinical picture of the studied adolescents revealed more clearly the qualitatively new pathological properties of the personality due to the development of excitable, unstable, less often labile and hysterical manifestations. In contrast to psychopathic behavior in sick children and adolescents, no correlation was found between the first signs of deviant behavior and cerebrastenic disorders. In all cases, behavioral disturbances are caused by unfavorable micro-social factors. Based on the follow-up data, the study has found that the studied group of sick children and adolescents is characterized by both favorable dynamics (22) and a negative outcome (20 patients). This suggests that the pubertal period is characterized by a polymorphism of behavioral disorders and is one of the decisive factors in the prognosis of the further development of the child.

Full textAbstract:
Obesity is the major risk factor for early puberty, but emerging evidence indicates other factors including psychosocial stress. One key brain region notable for its role in controlling calorie intake, stress, and behavior is the amygdala. Early studies involving amygdala lesions that included the medial nucleus advanced puberty in rats. More recently it was shown that a critical site for lesion-induced hyperphagia and obesity is the posterodorsal subnucleus of the medial amygdala (MePD), which may explain the advancement of puberty. Glutamatergic activity also increases in the MePD during puberty without a corresponding γ-aminobutyric acid (GABA)ergic change, suggesting an overall activation of this brain region. In the present study, we report that neurotoxic lesioning of the MePD advances puberty and increases weight gain in female rats fed a normal diet. However, MePD lesioned rats fed a 25% nonnutritive bulk diet also showed the dramatic advancement of puberty but without the increase in body weight. In both dietary groups, MePD lesions resulted in an increase in socialization and a decrease in play fighting behavior. Chronic GABAA receptor antagonism in the MePD from postnatal day 21 for 14 days also advanced puberty, increased socialization, and decreased play fighting without altering body weight, whereas glutamate receptor antagonism delayed puberty and decreased socialization without affecting play fighting. In conclusion, our results suggest the MePD regulates the timing of puberty via a novel mechanism independent of change in body weight and caloric intake. MePD glutamatergic systems advance the timing of puberty whereas local GABAergic activation results in a delay.

Background: Adolescence is a transitional stage of physical and psychological development that generally occurs during the period from puberty to legal adulthood. It is marked by rapid physical growth and development with sexual maturity. The current study aims at assessing and reforming the perceptions affecting sexual behavior and attitude towards puberty, marriage, conception, STIs, HIV/AIDS and contraception among adolescent followed by appropriate training interventions.Methods: The study was conducted in an urban slum, on 110 adolescents of age 12 to 17 years in the field practice area of an urban health center in urban slum. A semi structured pretest and posttest Questionnaire administered to the study subjects with appropriate training interventions. The analysis was done using Microsoft Excel software.Results: Pretest showed that of only 19% of the adolescents could correctly mention half the physical changes occurring in boys during Puberty. Only 2% of the girls could mention the pubertal changes correctly. Awareness increased to up to 87% in boy’s and 51% in girls, who answered at more than half pubertal changes correctly in posttest respectively after teaching interventions. Perceptions about contraception, family planning STDs and HIV were also changed significantly after the interventions.Conclusions: Appropriate training about reproductive health is essential to sensitize the adolescents for the health empowerment at an early stage.

Full textAbstract:
BackgroundPuberty moderates genetic influences on disordered eating attitudes and behaviors, with little genetic influence before puberty but large (⩾50%) genetic effects during and after puberty. To date, however, nothing is known about the mechanisms that underlie these effects. Estradiol is a particularly promising candidate, as estrogens become elevated at puberty and regulate gene transcription within neurotransmitter systems important for eating-related phenotypes. The aim of this pilot study was to examine whether estradiol levels moderate genetic influences on disordered eating during puberty.MethodParticipants included 198 female twins (ages 10–15 years) from the Michigan State University Twin Registry. Disordered eating attitudes and behaviors were assessed with the total score, weight preoccupation, body dissatisfaction and binge eating/compensatory behavior subscales of the Minnesota Eating Behavior Survey (MEBS). Afternoon saliva samples were assayed for estradiol levels. Moderation of genetic effects was examined by comparing twin correlations in low versus high estradiol groups.ResultsIn the low estradiol group, monozygotic (MZ) and dizygotic (DZ) twin correlations for all MEBS scales were similar, suggesting little genetic influence. In the high estradiol group, the MZ twin correlation was more than double the DZ twin correlation, indicating the presence of genetic effects. Findings could not be accounted for by age, body mass index or the physical changes of puberty.ConclusionsEstradiol may be one important moderator of genetic effects on disordered eating during puberty. Larger twin studies are needed to replicate this pilot work and quantify the extent of genetic moderation.

Full textAbstract:
The premature onset of secondary sexual characteristics defines precocious puberty (PP). Neurofibromatosis type 1 (NF1), an autosomal dominant genetic disorder, has been associated with a variety of systemic manifestations, including endocrinopathy like precocious puberty. In children with NF1, there is an increased risk of developing an optic chiasmal tumor, which is the primary cause of central precocious puberty (CPP) but not the only one. Here we present a case of CPP due to NF1. A 6-year 10-month-old boy presented to us with a growth spurt and premature appearance of secondary sexual characteristics with aggressive behavior, occasional headaches, hyperphagia, café-au-lait spots & a positive family history of nodular skin disease. During thorough evaluation, pubertal gonadotropin response was established after gonadotropin-releasing hormone (GnRH) stimulation and imaging studies revealed an optic pathway glioma. This known NF1 complication can disrupt hypothalamic-pituitary axis function and trigger hormonal imbalances; in this patient, it specifically affected the GnRH axis. Subsequently, the patient was managed with GnRH analog therapy while awaiting definitive management. J Assoc Clin Endocrinol Diabetol Bangladesh, January 2024;4(1): 43-47

Background: Khejri (Prosopis cineraria) contains substantial amounts of polyphenols like tannin naturally and is preferable fodder by farmers for animal nutrition, having positive attributes for reproductive events like semen quality. However, the effect is not observed in sexual performance and semen attributes in pubertal rams. The present investigation is to study the effects of Khejri leaves feeding on pubertal age, sexual behavior, and semen parameters in weaned ram lambs. Methods: For the present study, 16 ram lambs were randomly divided into control (C) and treatment (T) considering the body weight and age uniform after weaning. Animals were individually stall-fed, with the Coffered Cenchrus + gram straw (2:1) and T with dried Khejri leaves @ 200 gm at initial two weeks to 1200 kg at advanced age with concentrate mixture common @ 300 gm/day/animal. The lambs were trained for semen donation at the age of 7 months once in a week intervals till attaining puberty. At puberty each male lambs were exposed to a mating session to record the sexual behavior and libido. Results: There was gradual increase in feed intake and body weight in T group rams than C group, resulting in higher mean scrotal morphology and body measurements values. Mounting was higher in T followed by C with non-significant value; however, there was significant (P<0.05) difference in duration of ejaculation with lower duration in T. Similarly, the number of ejaculation was also significantly (P<0.05) higher in T group.Libido score was similar in C and T group 2.85 and 2.82 respectively. The mean age of puberty was lower (P=0.16) in theT group as compared to the C group (232.66±7.96vs 257.4±9.92 days). The seminal parameters like mass motility, sperm concentration and semen volume also found to be significantly higherin tannin fed group than non-fed group.

Full textAbstract:
Neuroendocrine mechanisms underlying social inhibition of puberty are not well understood. Here, we use a model exhibiting the most profound case of pubertal suppression among mammals to explore a role for RFamide-related peptide-3 [RFRP-3; mammalian ortholog to gonadotropin-inhibitory hormone (GnIH)] in neuroendocrine control of reproductive development. Naked mole rats (NMRs) live in sizable colonies where breeding is monopolized by two to four dominant animals, and no other members exhibit signs of puberty throughout their lives unless they are removed from the colony. Because of its inhibitory action on the reproductive axis in other vertebrates, we investigated the role of RFRP-3 in social reproductive suppression in NMRs. We report that RFRP-3 immunofluorescence expression patterns and RFRP-3/GnRH cross-talk are largely conserved in the NMR brain, with the exception of the unique presence of RFRP-3 cell bodies in the arcuate nucleus (Arc). Immunofluorescence comparisons revealed that central expression of RFRP-3 is altered by reproductive status, with RFRP-3 immunoreactivity enhanced in the paraventricular nucleus, dorsomedial nucleus, and Arc of reproductively quiescent NMRs. We further observed that exogenous RFRP-3 suppresses gonadal steroidogenesis and mating behavior in NMRs given the opportunity to undergo puberty. Together, our findings establish a role for RFRP-3 in preserving reproductive immaturity, and challenge the view that stimulatory peptides are the ultimate gatekeepers of puberty.

Full textAbstract:
During puberty, rapid, complex hormonal, physical and cognitive changes occur that affect body image and eating behavior. The aim of this cross-sectional study, a secondary analysis of data from the Greek Healthy Growth Study, was to explore associations of disordered eating behaviors and body image in 1206 10–12-year-old girls during pubertal maturation, with serum leptin and adiponectin levels, according to body mass index (BMI). Eating behavior and disordered eating were assessed with the Dutch Eating Behavior Questionnaire (DEBQ) and the Children Eating Attitudes Test Questionnaire (ChEAT), respectively. Associations of components of DEBQ and ChEAT with maturation according to Tanner Stage (TS) and levels of leptin and adiponectin were explored by univariate and multivariate regression analysis. Adiponectin levels in girls at TS 1 were positively associated with the “social pressure to eat” score of ChEAT. Leptin levels in girls at TS 4 were positively correlated with the “restraint eating” score of DEBQ, and the “dieting”, “body image” and “food awareness” scores of ChEAT. After adjustment for TS and BMI, only “body image” and leptin remained significant. Further research may shed light on how these hormonal changes affect eating behaviors at various pubertal stages, contributing to “TS-specific” preventive strategies for eating disorders in girls.

This research is motivated by the change in behavior of students entering puberty. This study was conducted to determine (1) the behavior of puberty, (2) learning achievement, (3) the relationship of puberty behavior to learning achievement in class VI SDS Tunas Harapan Tangerang Regency. This study uses a type of quantitative research with survey methods, while the techniques used are observation, interviews, documentation and questionnaires. The total population is 92 students in class VI in one private elementary school in Tangerang Regency with sampling techniques using purposive sampling for research as many as 30 students consisting of 10 students in class VI A, 10 students in class VI B, and 10 students in class VI C on the school. The research instrument used was questionnaires that had previously been tested for validity. Hypothesis testing is done using the Product Moment correlation formula, which begins with a normality test of the data obtained. Based on the results of the study, there is a significant positive relationship between the behavior of puberty (X) on learning achievement (Y). This is evidenced by the implementation of the Product Moment correlation test which yielded 0.479 in the interval 0.40 - 0.59 which means that it has a sufficient / moderate correlation. And for the hypothesis obtained data for the value of t count = 2.886 while t table 0.05 = 2.048. This shows that the value of t count> t table means the research hypothesis (H1) is accepted. From the results of this study, it can be concluded that there is an influence between the behavior of puberty on the learning achievement of SDS students in Tangerang Regency.

The Indonesian adolescents’ knowledge on the subject of puberty is very limited according to a national data survey. This is the reason this study aims to increase knowledge, attitudes, and behaviors of healthy living during the puberty phase through the contextual teaching and learning (CTL) method of classroom action research with cyclical procedures. The participants were 20 students and a teacher of fifth-year at the elementary school; meanwhile, the object was knowledge about puberty, collected through test questions and observations. The data analysis technique was conducted in a quantitative and qualitative descriptive manner, and the result showed that the method used was able to improve the knowledge, attitudes, and healthy living behavior of fifth-grade students in SDIT Mutiara Insan. This is evident in the pre-cycle with a percentage of 5.3%, which further increased to 15.8% in the first cycle, while in the second cycle, it increased to 94.7%.

Full textAbstract:
The study is based on grooming activity in different age class members of Semnopithecus entellus entellus all-male bands (AMB). All males seem to reach a peak in grooming frequency during and immediately following puberty and it is suggested that this peak corresponds to a period of establishing coalition bonds. High grooming rates may also be found in young adults who are actively and assertively challenging higher-ranking individuals. Finally, some old males exhibit paternalistic behavior toward young (generally pre-pubertal) males, which includes grooming, co-feeding and active defense by the older male. These observations are consistent with the hypothesis than grooming is an instrumental behaviour analogous to human gift exchange, which can be “used” by an individual for his ultimate benefit.

<strong>ABSTRACT</strong> <strong>Introduction:</strong> Adolescence is a developmental age characterized by conflicts, emotional instability, psychological and physical changes that pose various health risks such as unsafe sexual behavior, risky driving and substance dependence. <strong>Aim</strong>: A systematic review aimed at capturing the factors that are due to dangerous behaviors and which include teenagers in the high risk group. <strong>Methodology</strong>: Systematic review of studies that have analyzed issues of puberty behavior. The search for relevant domestic and international bibliography was conducted in the Google Scholar, Scopus, Science Direct and PubMed online databases, covering the 2008-2018 period, with keywords to identify the appropriate articles/ studies and setting selection/ exclusion criteria for their inclusion in the job. <strong>Results</strong>: Dangerous behaviors are a complex phenomenon and are largely influenced by the social context in which young people live. Adolescents are generally regarded as one of the healthiest populations compared to other age groups. However, the literature highlights the substantial risk of mortality in this age group at a global level, which is mainly due to high-risk behavior in adolescence. <strong>Conclusions</strong>: The reduction in adolescent mortality due to high-risk behaviors is demonstrated through the implementation of appropriate strategies including, among others, access to contraceptive methods and the organization of family planning services, training and support for young girls on safe pregnancy termination, policies for greater safety in driving and avoiding accidents, organizing mental health services for teenagers.

Maternal alcohol consumption during critical periods of fetal brain development leads to devastating long-term consequences on adult reproductive physiology, cognitive function, and social behaviors. However, very little is known about the long-term consequences of alcohol consumption during puberty, which is perhaps an equally dynamic and critical period of brain development. Alcohol abuse during adulthood has been linked with an increase in clinically diagnosed anxiety disorders, yet the etiology and neurochemical mechanisms of alcohol-induced anxiety behavior is unknown. In this study, we determined the effects of binge ethanol exposure during puberty on two critical central regulators of stress and anxiety behavior: corticotrophin-releasing hormone (CRH) and arginine vasopressin (AVP). Our results showed that ethanol increased plasma corticosterone (CORT) levels in both sexes, yet binge-treated animals had significantly lower CORT levels than animals exposed to a single dose, suggesting that the hypothalamo-pituitary-adrenal (HPA) axis habituated to the repeated stressful stimuli of ethanol. Binge ethanol exposure also significantly increased CRH and AVP gene expression in the paraventricular nucleus of males, but not females. Overall, our results demonstrate that binge ethanol exposure during puberty changes the central expression of stress-related genes in a sex-specific manner, potentially leading to permanent dysregulation of the HPA axis and long-term behavioral consequences.

The endocrinology and somatic events of puberty have been well described, and their assessment is incorporated routinely into the evaluation of the adolescent patient. Because of the increasing collaboration between behavioral scientists and physicians who share an interest in the developing adolescent, understanding of the interactions between the physical, cognitive, and psychological experiences of this age group has grown. Examining the contextual and possible predictive implications of variations in pubertal events and their timing will help the pediatrician to guide and counsel adolescents and their parents. Findings from recent research have highlighted the salience of gender differences in the experience of puberty and in the timing of its onset and tempo as well as the importance of being earlier in maturation rather than synchronous or later than one's peers. In this article, we will consider the findings in four major domains: 1) the effect of adolescent development on family homeostasis; 2) the implications for cognitive development; 3) the implications for personality (psychological) development; and 4) the recognition of risk factors or markers for problem behavior. Pubertal Development and Family Homeostasis One of the earliest tasks of adolescence is to separate from the family emotionally in preparation for developing independence. For girls, pubertal development may be the signal to their fathers to be less physically affectionate.

Abstract. Indonesia is experiencing a demographic bonus, and a good education and health situation will determine the quality of human resources so that this situation does not turn into a demographic burden or disaster. The Indonesian Adolescent Reproductive Health Survey shows the in-depth knowledge of adolescents about puberty, whereas adolescence is a golden period that will determine the quality of the next generation. This study aims to get a picture of the perception of teachers and students in particular about puberty and its relation to religion. The approach used is qualitative, data collected by conducting in-depth interviews with teachers, parents, and students. There were ten informants, consisting of teachers, parents, and students from 2 public and religious-based elementary schools in North Jakarta. In general, teachers have low knowledge / understanding of puberty, as well as students' knowledge. Most teachers have the perception that education about puberty in the classroom, according to the curriculum, turns out to be too vulgar so that some information is not conveyed to students. Religion is considered as the most reliable foundation in shaping student behavior. Teachers tend to hand over responsibility to religious teachers to deliver material on puberty, at religiously-based schools specifically mentioned teachers of fiqh. Teacher capacity building is needed regarding the material that must be taught, and it is delivery methods to suit the needs of students and have an impact on improving knowledge and improving behavior.Abstrak. Indonesia sedang mengalami bonus demografi dan situasi pendidikan dan kesehatan yang baik sangat menentukan kualitas sumber daya insani agar situasi ini tidak berbalik menjadi beban atau bencana demografi. Survei Kesehatan Reproduksi Remaja Indonesia memperlihatkan rendahnya pengetahuan remaja tentang pubertas, padahal masa remaja merupakan periode emas yang akan menentukan kualitas generasi berikutnya. Penelitian ini bertujuan mendapatkan gambaran persepsi guru dan peserta didik di khususnya tentang pubertas dan kaitannya dengan agama. Pendekatan yang digunakan yaitu kualitatif, data dikumpulkan dengan melakukan wawancara mendalam kepada guru, orang tua, dan peserta didik. Jumlah informan 10 orang, terdiri dari guru, orang tua, dan peserta didik dari 2 sekolah dasar umum dan berbasis agama di Jakarta Utara. Secara umum guru memiliki pengetahuan/pemahaman yang rendah tentang pubertas, demikian pula pengetahuan peserta didik. Kebanyakan guru memiliki persepsi bahwa edukasi tentang pubertas di kelas sesuai kurikulum ternyata dianggap terlalu vulgar sehingga sebagian informasi tidak disampaikan kepada peserta didik. Agama dianggap sebagai landasan paling diandalkan dalam membentuk perilaku peserta didik. Guru cenderung menyerahkan tanggung jawab kepada guru agama untuk menyampaikan materi tentang pubertas, pada sekolah berbasis agama disebutkan secara spesifik guru fiqih. Dibutuhkan pengembangan kapasitas guru tentang materi yang harus diajarkan dan metode penyampaiannya agar sesuai dengan kebutuhan peserta didik dan berdampak terhadap peningkatan pengetahuan serta perbaikan perilaku.

Puberty affects some teenagers more strongly than others and influences some behaviors more strongly than others. Body image, interest in dating and sexual behavior are influenced by changes during puberty. The aim of this research was to determine the relationship between knowledge of teenagers about sex education and behavior that leads to free sex in Cibadak Village, Cikupa District. The population in this study was 30 respondents, using a proportional random sampling technique. Data analysis uses multiple linear regression. The instrument used is a questionnaire. The results of the analysis from multiple linear regression are Y = 3.501 - 0.297X1 - 0.309X2 so that from this research the R2 coefficient of determination value is 0.615. With a p value = 0.000, which means the significance value is <0.05, which means there is a relationship between knowledge, attitudes of teenagers regarding sex education and behavior that leads to free sex. The conclusion from this research is that there is a significant relationship between knowledge and attitudes of teenagers regarding sex education and behavior that leads to free sex in Cibadak Village, Cikupa District.

ABSTRACTBackgroundLongitudinal, genetically informed, prospective data collected on a large population of male twins (n=1037) were used to examine developmental differences in the etiology of antisocial behavior.MethodAnalyses were carried out on both mother- and child-reported symptoms of conduct disorder (CD) in 10- to 17-year-old twins from the Virginia Twin Study of Adolescent Behavioral Development (VTSABD) and self-reported antisocial behavior by the twins as young adults from the Young Adult Follow-Up (YAFU) study.ResultsThe following trends were identified: (1) a single genetic factor influencing antisocial behavior beginning at age 10 through young adulthood (‘life-course persistent’); (2) a shared-environmental effect beginning in adolescence (‘adolescent-onset’); (3) a transient genetic effect at puberty; and (4) a genetic influence specific to adult antisocial behavior.ConclusionsOverall, these etiological findings are consistent with predictions from Moffitt's developmental theory of antisocial behavior. The genetic effect at puberty at ages 12–15 is also consistent with a genetically mediated influence on the timing of puberty affecting the expression of genetic differences in antisocial outcomes.

Background. Male adolescents with constitutional delay of growth and puberty may have significant psychosocial difficulties related to their sexual immaturity and short stature. The purpose of this study was to test the hypothesis that 1 year of oxandrolone therapy would increase growth velocity and thereby improve psychosocial functioning in boys with constitutional delay of growth and pubertal development. Methods. Forty boys (ages 11 to 14.7 years) with delayed pubertal development and short stature were recruited from the pediatric endocrine clinics of 14 medical centers. The boys were randomized using a block design stratified for age to receive either oxandrolone (0.1 mg/kg daily for 1 year) or an identical-appearing placebo tablet, using a double-masked design. Results. Growth velocity in the oxandrolone-treated boys was significantly greater than in the control boys (9.5 vs 6.8 cm/y). Likewise, the mean height SD score increased 0.41 in the oxandrolone group, whereas it decreased 0.03 in the control group. Those in the oxandrolone group gained 2.4 kg more than those in the placebo group. Mean predicted adult heights did not change in either group. The mean rates of pubertal progression were equivalent in both groups. Self-image (Piers-Harris Self Concept Scale) and social competence (Child Behavior Profile) were normal at baseline in both groups and did not change significantly over the course of the study in either group. No complications of oxandrolone therapy were identified. Conclusions. This randomized, placebo-controlled trial demonstrates that low-dose oxandrolone can increase both height and weight velocity in boys with delayed puberty safely. Under the conditions of this study, however, the increased growth velocity in the oxandrolone-treated boys was not associated with a greater improvement in psychosocial status compared with the control boys.

Abstract The objective of this study was to assess the current use of patient-centered psychosocial assessments for the evaluation of children with central precocious puberty (CPP). Studies evaluating the psychosocial impact of CPP were identified through searches of the PubMed and Cochrane Library databases, ClinicalTrials.gov, a drug prescribing information database, and regulatory websites. Studies were screened using prespecified inclusion and exclusion criteria. Potentially relevant patient-centered outcome assessments (including patient-, parent- or observer-reported measures) used in the identified studies were evaluated in detail for their relevance in CPP. Of the 467 studies identified, 15 met the inclusion criteria. Frequently assessed concepts included depression and anxiety, behavior and behavioral problems, body image and self-esteem and personality type/characteristics. Among the assessments used in the identified studies, the Child Behavior Checklist, Pediatric Quality of Life Inventory (PedsQL), SF-10 for Children and Child Health Questionnaire were comprehensively evaluated. The PedsQL showed promise as a patient-centered outcome measure in CPP. Although there is a lack of validated tools measuring psychosocial health and health-related quality of life in patients with CPP, the PedsQL captures issues seen in this patient population and is relatively easy to administer. Further studies using this and other tools in children with CPP are needed.
