Full textENGLISH ABSTRACT: Introduction: Adolescents are recognised as a nutritionally at-risk group, as they have high nutritional demand for growth and development, poor eating behaviour as well as a propensity for unhealthy behaviours. Heavy alcohol use, particularly in the form of binge drinking, is typical for an alarming proportion of school-going adolescents and is a plausible contributor to the nutritional challenges in adolescents, but this has not yet been fully investigated. Aim: This study investigated the potential influences of alcohol use on the nutritional status of adolescents with alcohol use disorders (AUDs), specifically with regards to their eating behaviour and dietary intake, growth and weight status, iron status, as well as vitamin D and calcium status. Methods: Substance use, physical activity, eating behaviour, dietary intake, growth and weight status, iron status and vitamin D and calcium status were assessed and compared in heavy drinking adolescents (meeting DSM-IV criteria for AUDs) (n=81) and in light/non-drinking adolescents without AUDs (non-AUDs)(n=81), matched for age, gender, language, socio-economic status and education. Observed dietary intake distributions were adjusted statistically to obtain usual nutrient intake distributions. Regression-adjusted differences between the groups were assessed using multi-level mixed effects linear regression, adjusting for potential confounders. Results: Lifetime alcohol dose in standard drinks of alcohol was orders of magnitude higher in the AUDs group compared to the non-AUDs group. AUDs adolescents had a binge alcohol use pattern and a “weekends-only” style of alcohol consumption. Poor eating patterns (breakfast skipping and frequent snacking), poor food choices (energy-dense and nutrient-poor foods) and low fruit and vegetable intake (non-AUDs 90 [42.4-153.3]; AUDs 88.3 [30.0-153.0] grams per day) in both groups were reflected in the poor nutritional quality of the diet. More than half of adolescents in both groups were at risk of inadequate intakes of folate (non-AUDs 97.5%; AUDs 98.8%), vitamin C (non-AUDs 65%; AUDs 67.5%), vitamin A (non-AUDs 80%; AUDs 82.5%), vitamin E (non-AUDs 78.8%; AUDs 51.3%), magnesium (non-AUDs 98.8%; AUDs 97.5%), and phosphorus (non-AUDs 76.3%; AUDs 73.8%) and all participants were at risk of inadequate calcium and vitamin D intakes. AUDs adolescents had a greater intake of unhealthy foods (energy-dense nutrient-poor) and a significantly greater energy intake than non-AUDs adolescents (p<0.001) that exceeded energy requirements. AUDs adolescents consumed foods high in unhealthy fats significantly more frequently (p=0.037) than the non-AUDs adolescents and had ensuing greater total fat (p<0.001), saturated fat (p<0.001) and cholesterol (p=0.009) intakes. Frequency of intake of sodium-rich foods was significantly higher in AUDs adolescents (p=0.001) and prevalence of risk of excessive sodium intake was significantly greater in the AUDs adolescents (45%) compared to non-AUDs adolescents (18.8%) (p<0.001). Anthropometric indices of growth and weight status were comparable between the groups and in line with that of the South African adolescent population. Female AUDs adolescents had increased odds (OR 2.42) of being overweight/obese compared to non-AUDs females. Physical activity in both groups was well below the WHO global recommendation. Iron store depletion (serum ferritin < 20 μg/L) was evident in a quarter of adolescents in both groups (non-AUDs 23.5%; AUDs 24.7%), with biochemical iron status measures (serum iron and total iron binding capacity) indicating a greater risk of iron store depletion in the AUDs group. Biochemical vitamin D insufficiency/deficiency (serum 25-hydroxyvitamin D < 30 ng/mL) was prevalent in both groups (non-AUDs 70.4%; AUDs 88.8%), although this was significantly greater in the AUDs group (p=0.013), with significantly lower serum 25-hydroxyvitamin D levels in the AUDs group compared to the non-AUDs group (p=0.038). Conclusions: Heavy alcohol use in the form of binge drinking in adolescents may have the following nutrition-related influences: increased intake of energy; unhealthy fats and sodium, increased risk of overweight/obesity in females; increased risk of iron store depletion; and increased risk of vitamin D insufficiency/deficiency. Persistence of heavy alcohol use, poor food choices and dietary intake may increase the risk for adverse nutrition-related health outcomes in the AUDs adolescents.
AFRIKAANSE OPSOMMING: Inleiding: Adolessente het 'n verhoogde risko vir wanvoeding as gevolg van hul hoë voedingbehoeftes vir groei en ontwikkeling, swak eetgedrag, asook 'n geneigdheid tot verdere ongesonde gedrag. Swaar alkohol gebruik in die vorm van “binge” drinkery kom toenemend onder skoolgaande adolessente voor. Hierdie gedrag kan moontlik bydra tot die verhoogde voeding risiko in dié ouderdomsgroep. Hierdie moontlikheid is egter nog nie ten volle ondersoek nie. Doel: Hierdie studie het die potensiële invloed van alkohol gebruik op die voedingstatus van adolessente met alkohol gebruik versteurings (AGVs) ondersoek, spesifiek met betrekking tot hul eetgedrag en dieetinname, groei en gewigstatus asook yster-, vitamien D- en kalsiumstatus. Metodes: Swaar drinkende adolessente wat voldoen aan DSM-IV kriteria vir AGVs (n=81) en lig/nie-drinkende adolessente sonder AGVs (nie-AGVs) (n=81), wat afgepaar is vir ouderdom, geslag, taal, sosio-ekonomiese status en opvoedingsvlak is gewerf vir deelname aan die studie. Middel gebruik, fisiese aktiwiteit, eetgedrag, dieetinname, groei en gewigstatus, ysterstatus en vitamien D- en kalsiumstatus is tussen die twee groepe vergelyk. Waargenome dieetinname verspreidings is statisties aangepas om gewoontelike nutriëntinname te verkry. Regressie-aangepaste verskille tussen die groepe is met behulp van ’n meervoudige gemengde effekte liniêre regressie model getoets, waartydens daar vir moontlike gestrengelde faktore aangepas is. Resultate: Leeftyd alkohol dosis, gemeet in standaard alkohol drankies, was beduidend hoër in die AGVs groep in vergelyking met die nie-AGVs groep. Alkohol gebruik in die AGVs adolessente het ‘n “binge” patroon en ‘n “slegs naweke” styl getoon. Swak eetgewoontes (oorslaan van ontbyt en gereelde peuselgewoontes), swak voedsel keuses (energie-dig en laag in nutriënte) en lae groente en vrugte inname (nie-AGVs 90.0 [42.4-153.3]; AGVs 88.3 [30.0-153.0] gram per dag), in beide groepe, is gereflekteer in die swak voeding kwaliteit van die dieet. ‘n Risiko vir onvoldoende inname van folaat (nie-AGVs 97.5%; AGVs 98.8%), vitamien C (nie-AGVs 65%; AGVs 67.5%), vitamien A (nie-AGVs 80%; AGVs 82.5%), vitamien E (nie-AGVs 78.8%; AGVs 51.3%), magnesium (nie-AGVs 98.8%; AGVs 97.5%), en fosfor (nie-AGVs 76.3%; AGVs 73.8%) was teenwoordig in meer as helfte van adolessente in beide groepe, asook Inleiding: Adolessente het 'n verhoogde risko vir wanvoeding as gevolg van hul hoë voedingbehoeftes vir groei en ontwikkeling, swak eetgedrag, asook 'n geneigdheid tot verdere ongesonde gedrag.

Full textBackground: Risky behaviours are notably the most important factors contributing to negative health outcomes among adolescents. A number of diseases and deaths have been linked to risky and harmful behaviours. Research has shown that being involved in one risky behaviour increases the likelihood of involvement in additional risky behaviours. Adolescents have been identified at the centre of sustainable development, particularly in achieving goals related to bringing poverty to an end, promoting health and well-being, attaining equitable and quality primary and secondary education as well as achieving inclusive and sustainable economic growth. Objectives: The objective of this study was firstly to examine the levels of social association membership and risky behaviour among adolescents. Secondly, to identify the determinants of risky behaviour among South African adolescents and lastly, to examine the relationship between social association membership and risky behaviour among adolescents. Methods: Data were drawn from the South African Youth Life Style Survey of 2008. A sample of 3335 adolescents aged 12 to 19 years was analysed. Four binary and one multinomial logistic regression analyses were conducted. The four binary dependent variables were for risky sexual behaviours, risky substance use behaviours, other risky behaviours and engaging in at least one type of behaviour. For each of these binary dependent variables the response category was yes or no. The dependent variable for the multinomial logistic regression model was any adolescent risky behaviour which was categorised as; no behaviour, any one category of behaviour, any two categories of behaviour and all three categories of behaviour. The key independent variables were firstly an index variable generated by merging all the different social associations into one variable that had the response yes or no to being a member of any social association. There were also five key independent variables that were the individual social associations namely; sports, religious groups, choir, drama and other associations. Results: The two most common social associations that adolescents engaged in were sports groups (515 per 1000 adolescents) and religious groups (342 per 1000 adolescents). Risky vii behaviours with the highest number adolescents engaging in them were driving without a seatbelt (32%), consuming alcohol (32%), being a passenger in a car driven by someone under the influence of alcohol (28%), tobacco use (21%) and lack of condom use (9%). Adolescents who were not members of social associations were found to have decreased the risk of engaging in one, two and all three categories of risky behaviours. Not being a member of religious groups increased the risk of engaging in one, two and all three categories of risky behaviour. Adolescents who were not members of sports groups were found to have lower risks of engaging in one, two and all three categories of risky behaviour, as well as decreased odds of engaging in at least one type of risky behaviour. Conclusion: The study found that there was a statistically significant relationship between social association membership and risky behaviours among adolescents in South Africa. More particularly, religious associations were found to be protective factors to risky behaviours and sports, drama and other associations were found to be platforms that could potentially increase the likelihood of risky behaviour among adolescents.

Full textNicotine is one of the most widely abused drugs in the world, and most smokers begin smoking during their adolescent years. Adolescence is a unique developmental period during which vulnerability to the effects of drug exposure is especially high. This dissertation uses rodent models to investigate the persistent effects of adolescent nicotine exposure on both neurobiological and behavioral measures of drug sensitivity in adulthood. The aims of this dissertation were to 1) determine whether nicotine would be self-administered into the posterior ventral tegmental area (pVTA), a neuroanatomical component of the mesolimbic dopamine (DA) system, which is known to be involved in reward and reinforcement; 2) investigate whether adolescent nicotine exposure would alter the sensitivity of the mesolimbic DA system as measured by DA release in the nucleus accumbens (NAc) in response to nicotine microinjections into the pVTA; 3) examine the effects of adolescent nicotine exposure on behavioral sensitization to nicotine in adulthood; and 4) investigate whether adulthood alcohol drinking behavior, in both Wistar and alcohol-preferring (P) rats, would be augmented by nicotine exposure during adolescence. Results of this dissertation demonstrated that 1) the pVTA is a neuroanatomical site that supports nicotine self-administration; and that adolescent nicotine exposure results in 2) increased nicotine-stimulated DA release in the NAc during adulthood; 3) augmented behavioral sensitization to nicotine in adult animals; and 4) enhanced acquisition of alcohol drinking behavior in adult Wistar and P rats. Overall, this dissertation provides insight into the diverse and persistent changes, in both neurobiology and behavior, caused by exposure to nicotine during the critical developmental period of adolescence.

Full textResearch in the alcohol preferring (P) rat has indicated that peri-adolescent alcohol (EtOH) consumption enhances the acquisition of oral operant EtOH self-administration, inhibits the extinction of responding for EtOH, augments EtOH-seeking behaviors, and increases relative reward value of EtOH during adulthood. Experiment 1 was conducted to determine if these adult effects of peri-adolescent EtOH intake could be observed using an Intracranial Self-Administration (ICSA) model. It was hypothesized that an increased sensitivity to the rewarding actions of EtOH would be manifested in peri-adolescent-EtOH-exposed subjects compared to naive subjects when the opportunity to self-administer EtOH to the posterior ventral tegmental area (pVTA) is available in adulthood. The pVTA is a primary site for EtOH’s reinforcing and rewarding properties in the mesolimbic dopamine (DA) system. Experiment 2 was a dose-response examination of the effects of EtOH administered to the pVTA on downstream DA efflux in the nucleus accumbens shell (AcbSh) via a joint Microinjection-Microdialysis (MicroMicro) procedure. Male P rats were given 24-h free-choice exposure to 15% volume/volume EtOH from postnatal day (PD) 30 to PD 60, or remained experimentally naive, with ad lib food and water. By the end of the periadolescent exposure period, average consumption was 7.3 g/kg/day of EtOH. After PD 75, periadolescent-EtOH-exposed and naïve rats were either implanted with an injector guide cannula aimed at the right pVTA for ICSA (Experiment 1), or two cannulae, one aimed at the right pVTA (injector) and one at the ipsilateral AcbSh (microdialysis) for MicroMicro (Experiment 2). Following one week of recovery from surgery, ICSA subjects were placed in standard two-lever (active and inactive) operant chambers. Test sessions were 60 min in duration and occurred every other day for a total of 7 sessions. Rats were randomly assigned to one of 5 groups (n=4-9/group) that self-infused (FR1 schedule) either aCSF (vehicle, 0 mg%), 50, 75, 100, or 150 mg% EtOH during 4 sessions, aCSF only for sessions 5 and 6 (extinction), and the initial concentration again for session 7 (reinstatement). MicroMicro subjects received six days of recovery from surgery, probe implantation the day before testing, and then continuous microdialysis for DA with 15 min microdialysis samples collected before, during, and then two hrs after 10-min pulse microinjection of either aCSF (vehicle, 0 mg%), 50, 75, 100, or 150 mg% EtOH. Neither EtOH-exposed nor naive groups of P rats self-infused the aCSF or 50 mg% EtOH concentration. While the naive group did not self-infuse the 75 or 100 mg% EtOH concentrations, the peri-adolescent EtOH-exposed group of P rats did readily discriminate the active lever from the inactive lever at these concentrations. Both groups self-infused the 150 mg% EtOH concentration. Pulse microinjections of EtOH during the MicroMicro procedure revealed that 75 and 100 mg% concentrations of EtOH increased downstream DA in the AcbSh of EtOH-exposed, but not naïve, subjects. 150 mg% EtOH increased downstream DA in both adolescent treatment groups. Overall, the results indicate that consumption of EtOH by P rats during peri-adolescence increases the reinforcing properties of EtOH in the pVTA in adulthood. The results also indicate that there were differential effects of peri-adolescent EtOH exposure on DA efflux in the AcbSh. This provides evidence that peri-adolescent EtOH-exposure produces long-lasting alterations in neural circuitry involved in EtOH-reinforcement, during adulthood.

Full textAbuse of alcohol during adolescence continues to be a problem, and it has been shown that earlier onset of drinking predicts increased alcohol abuse problems later in life. High levels of impulsivity have been demonstrated to be characteristic of alcoholics, and impulsivity has also been shown to predict later alcohol use in teenage subjects, showing that impulsivity may be an inherent underlying biological process that precedes the development of alcohol use disorders. These experiments examined adolescent drinking in a high-drinking, relatively impulsive mouse population, and assessed its effects on adult drinking and adult impulsivity. Experiment 1: Selectively bred High-Alcohol Preferring (HAP II) mice, which are shown to be highly impulsive, were given either alcohol (free choice access) or water only for two weeks during middle adolescence or adulthood. All mice were given free choice access to alcohol following 30 days without access, in adulthood. Experiment 2: Adolescent HAP II mice drank alcohol and water, or water alone, for two weeks, and were then trained to perform a delay discounting task as adults to measure impulsivity. In each experiment, effects of volitional ethanol consumption on later behavior were assessed. We expected adolescent alcohol exposure to increase subsequent drinking and impulsivity. Adolescent mice consumed significant quantities of ethanol, reaching average blood ethanol concentrations (BECs) of 142 mg/dl in Experiment 1 and 108 mg/dl in Experiment 2. Adult mice reached average BECs of 154 mg/dl in Experiment 2. Mice pre-exposed to alcohol in either adolescence or adulthood showed a transient increase in ethanol consumption, but we observed no differences in impulsivity in adult mice as a function of whether mice drank alcohol during adolescence. These findings indicate that HAP II mice drink intoxicating levels of alcohol during both adolescence and adulthood, and that this volitional intake has long-term effects on subsequent drinking behavior. Nonetheless, this profound exposure to alcohol during adolescence does not increase impulsivity in adulthood, indicating that long-term changes in drinking are mediated by mechanisms other than impulsivity. Importantly, this research demonstrates that the HAP II mouse is a good candidate for a model of heavy adolescent alcohol consumption.
