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.

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.

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.

Diharapkan program promosi kesehatan ini terus berlanjut sehingga membentuk generasi remaja yang berkualitas. 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:
Some early puberty girls engage in high-risk externalizing behaviors such as early sexual activity, delinquent behavior, and disruptive behaviors. Harsh parenting experienced by girls who develop early has been associated with delinquent and disruptive behaviors. The purpose of this quantitative correlational study was to examine predictive relationships between the style of parental discipline by mothers of early puberty girls and the likelihood and frequency of the girls' engagement in high-risk behaviors. Parenting style theory, including the authoritarian, authoritative, and permissive style of parenting, served as the theoretical foundation for the study. Survey data were collected from 28 mothers who identified as having a daughter who experienced early puberty. The Parenting Scale subscales were used to measure the dysfunctional parenting behaviors of laxness, overreactivity, and verbosity. Logistic regression analysis revealed no statistically significant relationships between the early puberty girl's involvement in risky behaviors and dysfunctional parenting. Results may be used by human service and public health officials to increase awareness of early puberty and to promote public health policies to address the individual, social, and economic implications of early puberty in girls.

Full textAbstract:
Research suggests that the temporary rise in adolescent antisocial behaviour (ASS) is attributable to a very large number of young people each engaging in a relatively small number of ASS's while progressing through adolescence. One possible explanation for the temporary increase in ASS during adolescence is that during puberty, the cognitive processes responsible for monitoring and controlling behaviour are disrupted. In support of this, recent research has found that adolescents' participation in ASS is positively correlated with the stage of pubertal development rather than age. Additionally, there is evidence that a temporary 'dip' in executive functioning (planning, organizing, decision-making) occurs at an age range (Le. 11-14 years) typically associated with the onset of puberty. This thesis reports a first test of a model which proposes a causal relationship between puberty, decreased executive function and increased antisocial behaviour. Self-report data on pubertal development, antisocial attitudes and ASS participation were collected from 323 boys and girls (ages 9 -17 years) attending New South Wales public schools. Executive function, (Le. updating, response inhibition, set-shifting) was measured in a 3D-minute individual interview. Data were analysed to determine if participants reported greater participation in ASS during puberty onset and whether this period was also characterized by a decline in executive function. In addition, it was investigated whether adolescents who attain puberty earlier than their peers participate in ASS earlier, longer, and at higher rates than their 'on-time' or 'late-maturing' peers, and whether there was an association between 'early' puberty and a persistent reduction in executive function. Results revealed that ASS participation was significantly associated with puberty onset timing, and some significant associations were found between antisocial attitudes and pubertal timing. There was some indication of decreased executive function at puberty onset and a link between early pubertal timing and a persistent reduction in executive function. Thus, there is some partial evidence to support the proposed model of adolescent ASS. However, complications in performing mediation analysis prevent concluding that executive function mediates the relationship between pubertal development and ASB. The implications of these findings are discussed with reference to future research in this field.

Full textAbstract:
Chez les rongeurs, les facteurs sociaux sont connus pour pouvoir moduler la transition pubertaire. Ainsi une jeune souris femelle mise en contact avec un mâle adulte présentera une ouverture vaginale plus précoce qu’une femelle isolée du mâle. L’objectif de ma thèse a été de caractériser les conséquences d’une exposition précoce au mâle dans l’espèce caprine. Les caprins sont une espèce dont la reproduction est saisonnée et permettant, de par sa taille, une étude plus fine des sécrétions endocrines que les rongeurs. Nos résultats ont permis de mettre en évidence que la présence de boucs sexuellement actifs induit une puberté précoce chez les chevrettes, l’ovulation pouvant être induite dès l’âge de 3 mois et demi. Les femelles présentent suite à cette première ovulation une cyclicité régulière ainsi qu’une maturation précoce du tractus génital. Le niveau d’activité sexuelle du bouc est un facteur crucial à l’induction d’une puberté précoce chez la chèvre puisque la présence de mâles castrés n’a aucun effet et que les femelles sont toutes pubères dans le mois suivant l’entrée en saison sexuelle des mâles. Ce travail démontre, dans l’espèce caprine, un rôle crucial de l’environnement social dans la régulation de la maturation sexuelle. Plus particulièrement, cela met en évidence que la présence de boucs peut réactiver efficacement et de manière très précoce l’axe gonadotrope de jeunes chèvres immatures<br>In rodents, social factors are known to modulate the pubertal transition. Hence, young female mice exposed to adult male exhibit an earlier vaginal opening than young females isolated from male. The aim of my thesis was to characterize the consequences of a precocious exposure to male in another specie, goats. Goats are seasonal breeders and due to their size the fine study of endocrine secretions is easier than in rodents. Our results highlighted that an early exposure to sexually active bucks induces a precocious puberty in young female goats. The first ovulation can be induced as early as 3.5 months old, following this induced first ovulation, goats remain cycling regularly. Females precociously exposed to bucks also exhibit an acceleration of the genital tract maturation. The level of sexual activity of the male is a crucial criteria to induce a precocious puberty in goats as exposure to castrated bucks had no effect on the age at puberty. Moreover, all females exposed to intact bucks ovulated for the first time within a month after buck started to exhibit sexual behaviors. This work revealed, in goats, a crucial role of the social environment on the regulation of sexual maturation. More precisely, it highlights that exposure to bucks is highly efficient to reactivate precociously the gonadotrope axis of youg immature goats

Full textAbstract:
The objective of the current study was to investigate the relationships between changing pubertal status, body composition, body image, and time spent in sedentary behaviours during adolescence. A mixed-longitudinal design was used involving 119 students from school Years 6 (10.0 - 10.9 years of age), 8 (12.0 - 12.9 years) and 10 (14.0 - 14.9 years). Participants were assessed in three phases carried out at six-month intervals. Cross-sectional results from Phase 1 showed that time spent in sedentary behaviours was significantly greater in participants who had started puberty compared with those who were pre-pubertal, and in those who were late-/post-pubertal compared with those who were pre-/early-pubertal. Also, students in Year 10 spent significantly greater time in sedentary behaviours compared with those in Years 6 and 8. These differences disappeared after controlling for the amount of time spent sleeping except for the Year 10 boys. It was concluded that differences in sedentary behaviour during adolescence were not associated with differences in behavioural choice related to greater maturity per se but to a greater opportunity for such behaviours with more waking hours. Longitudinal analysis examined changes between Phases 1 and 3. Analysis of covariance showed that, for boys only, weekday sedentary behaviour increased by a significantly greater amount for participants who increased puberty compared with those who stayed at the same pubertal level. No differences were found between pubertal groups for either gender during the weekend. No significant correlations were found between changing body composition and changing body image for boys or girls or between the change in pubertal status and change in body composition or body image. Multiple regression analysis showed that a significant amount of the variance of the increase in weekday sedentary behaviour could be explained by increased pubertal status for boys and reduced physical attractiveness for girls. When considering increasing weekend sedentary behaviour an increase in percentage body fat explained a significant amount of the variance for girls. It was concluded that only a part of the a priori hypothesis, that changes in sedentary behaviour are associated with pubertal changes, was supported by this data and that any changes found were not associated with behavioural choices triggered by body compositional changes.

Adolescent sexual intercourse can be viewed as a normal developmental experience, but intercourse also is linked to unplanned pregnancies, Sexually Transmitted Diseases (STDs). and Acquired Immune Deficiency Syndrome (AIDS). Consequently, there continues to be a high level of scientific interest in understanding antecedents of adolescent sexual behavior, especially early and more risky sexual intercourse. This study examined several key antecedents of adolescent sexual intentions and behavior, including pubertal development (pubertal status, change over time, and pubertal timing). parent/teen communication, and teen sexual values. Analyses were based on longitudinal data collected in 1991, 1992, and 1993 from parents and teens during the FACTS & feelings project conducted within three areas in northern Utah.
Regression and path analyses were used to test the direct and indirect effects among the variables. Parent/teen communication quality had a significant positive effect on teen sexual abstinent values for both males and females. Sexual abstinent values had a strong negative effect on sexual intentions for both males and females. Sexual values were more strongly related to sexual behavior for females than for males. Sexual intentions had a significant effect on sexual behaviors for both males and females, although this effect was stronger for males than for females. Pubertal timing had a significant effect on behaviors for males and a smaller although significant effect for females Age also had a significant positive effect for both male and female adolescents. Overall, within these analyses, females were more influenced by values which directly and indirectly affect sexual behaviors. Males were more influenced by the FACTS & feelings treatment, pubertal timing, and sexual intentions.

Full textAbstract:
Playing is a common behavior among juveniles of many mammalian species, including rats (Rattus norvegicus). The mechanisms underlying the change that occurs in the play fighting of male rats at puberty were the focus of this thesis. It was found that castration at weaning disrupted the formation of male-typical dominance relationships, but did not alter the pubertal changes in play fighting, whereas neonatal castration prevented the shift from juvenile- to adult-typical behaviour at puberty. This transistion is male specific and cannot be induced in females by exposing htme to more extreme social contexts,
involving interactions with unfamiliar males. The change in play by males at puberty is not, then, a byproduct of other sex differences, but results from a highly specific mechanism in early infancy. The significance of this sex difference is explored with respect to the functions of play fighting in rats and other species.<br>xii, 137 leaves : ill. ; 28 cm.

Full textAbstract:
AbstractThere are significant differences in morbidity (incidence of disease) and mortality (death rate) between men and women. By puberty, male adolescents are more likely to have health problems. During puberty, girls suffer from chronic and mental illnesses and male adolescents are more likely to suffer from acute and life-threatening diseases. Boys and men have riskier health behavior. The field of research mainly relates to the binarity of the sexes—men and women. Studies on trans and queer persons are rare in this field. Networks have a gender-specific effect on risk behavior. Women provide more and more time-consuming social support, even in case of illness. After widowhood, networks have both negative and positive effects, which are gender-specific.

Full textAbstract:
AbstractAge limits play an important role in various areas of law. In this chapter, we look at the psychological, biological and neuroscientific research on puberty, adolescence and adulthood. According to new proposals, adolescence extends from the age of ten to 24. While various studies suggest that cognitive development has reached adult level by the age of 16–20, researchers assume a longer process for emotional and social maturity. These views are compared with new findings on brain development. The question of the extent to which “typical” adolescent behavior is a reaction to psychosocial circumstances is also addressed. A specific “adolescent brain” cannot be identified based on current knowledge.

Full textAbstract:
Ontogeny, the development of an organism from conception to maturity, is one of Tinbergen’s two proximate explanations for understanding why we do the things we do. As well as genetic inheritance, the developmental environment, which parents make a large contribution to, is crucial for shaping a child’s life. It shapes not only their physical and psychological development but also influences the adult child’s reproductive strategy and ultimately their life expectancy. Demographers care about fertility and mortality which, when understood within an evolutionary framework, are two entwined processes that influence, and are in turn influenced by, the individual’s developmental trajectory. Here, we provide a summary of how development operates throughout life; from the womb, through childhood, adolescence and puberty, the reproductive years through to menopause and death. We take a life-history approach with a focus on how developmental influences during early life have long-reaching consequences for mortality and fertility. We illustrate each section with theoretical advances, empirical examples, and evaluation of the current literature. We hope to demonstrate that thinking about human demographic behavior in light of ontogeny can be revealing and provide a useful theoretical basis for demographic research.

Full textAbstract:
In 2019, approximately 29,000 children (up to 15 years of age) were involved in road traffic accidents in Germany. The cohorts with the most accident victims are the 11- to 14-year-olds, about half of whom (approx. 6,000 children) were involved in accidents by bicycle. The number of cyclists involved in accidents rises sharply after the transition from primary to secondary school. This is due to a change in driving behavior after the change of school compared to the primary school period. Many pupils start cycling to school after changing to secondary school. Furthermore, extensive behavioral changes occur with the onset of puberty, which, for example, increases the willingness to take risks in road traffic. SafeBike is a road safety program for the particularly vulnerable target group of 11 to 14-year-old cyclists based on observation procedures, self-reflection and personal responsibility. The basic aim of SafeBike is to raise students' awareness of danger perception when cycling, leading to an increased sense of safety in the short term, so that in the long term the number of cycling accidents in the target group will decrease. After participating in the program, students are expected to be more critical of their own behavior, among other things. SafeBike consists of three components: a self-assessment of one's own driving behavior in terms of safety, the treatment of several subject areas in which driving errors and traffic conflicts occur more frequently, and a final re-assessment of one's own driving behavior.The traffic effects of the program were surveyed and evaluated in a pilot test at two different schools in Germany. In the post-surveys, the test group committed about 50% fewer traffic conflicts and driving errors than the control group, which attests to the very high short-term effectiveness of SafeBike. In the control group, who did not complete the program, no significant improvements occurred in comparison to the before survey, in contrast to the subject group. In the test group, there were significant positive effects, especially in the case of driving errors that occurred particularly frequently in the pre-surveys and were correspondingly addressed in the program and discussed by the students. Particularly high positive effects were achieved with conversations while driving, at the pedestrian crossing and using the pavement on the wrong side of the road. Medium effects were achieved with hand signals and looking around. This means that the road safety program can be used in road safety education throughout the country. However, long-term effects are not yet available and must be determined in further studies.

Tuko Pamoja: A guide for talking with young people about their reproductive health. Population Council, 2005. http://dx.doi.org/10.31899/rh16.1017.
Full textAbstract:
This guide was developed for public health technicians working with the Ministry of Health as part of the Kenya Adolescent Reproductive Health Project Tuko Pamoja (We Are Together). It can be used by anyone wishing to broaden their understanding of adolescent reproductive health (RH) issues and improve communication with young people. Providing young people with support by talking with and listening to them as well as ensuring they have access to accurate information can help them understand the wide range of changes they are experiencing during adolescence. Although parents, teachers, religious and community leaders, and health-care providers are expected to educate adolescents about personal and physical development, relationships, and their roles in society, it may be difficult for them to do so in a comfortable and unbiased way. For these reasons, it is important to meet adolescents’ need for information and services. Adolescent RH education provides information about reproductive physiology and puberty; protective behavior; and the responsibilities and consequences that come with sexual activity. Providing young people with accurate RH information promotes sexual health and well-being, and supports healthy, responsible, and positive life experiences, as well as preventing disease and unintended pregnancy.
