Drunkenness and heavy drinking among 11year olds - Findings from the UK Millennium Cohort Study

Patterns of Accidental and Intentional Alcohol Intoxication Initiation among French Young Adults: A Survival Analysis

Background: The aim of the study was to explore patterns of accidental and intentional intoxication among French young adults who use alcohol. Methodology: The study draws on data from the 2017 French Health Barometer. Cox proportional hazards models were used to explore the factors associated with accidental and intentional alcohol intoxication initiation. Covariates studied were gender, age, employment status, consultation for mental health problems, depression lasting at least two weeks in the past 12 months, and previous tobacco or cannabis use as time-dependent variables. Results: Women accounted for 50.4% of our sample, and the mean age of respondents was 29.2 (standard deviation = 6.3). The prevalence of lifetime accidental intoxication among alcohol users was 77.0% and 17.3% for intentional intoxication. Kaplan-Meier analyses showed that the first intentional intoxication experience occurred later than the first accidental intoxication. Factors associated with accidental intoxication initiation in multivariate analyses were: male gender, age under 30, previous use of tobacco and cannabis, experiencing depression that lasted at least two weeks in the past 12 months, and having consulted for mental health problems in the past 12 months. Economically inactive people and students had a lower risk of experiencing accidental intoxication than those who were employed. Similar correlates were found for intentional intoxication, but being economically inactive was more strongly associated with intentional intoxication initiation. Conclusions: These results suggest the strong potential for alcohol consumption to become hazardous, particularly if tobacco or cannabis are also used. Prevention programs on alcohol must target consumers at the earliest stage and integrate other substances often used in a festive context.

Correlates of alcohol experimentation and drunkenness episodes among secondary-school students in Nigeria

Background: Alcohol is the most used substance among adolescents in Nigeria. While risk factors for alcohol use among adolescents are well documented in Europe and the US, they have received less attention in the literature on African countries. This study aimed to investigate the factors associated with alcohol experimentation and drunkenness episodes in a national sample of Nigerian adolescents. Methods: A total sample of 4,078 secondary-school students participated in the survey during the school year 2015-2016. The survey involved 32 secondary schools of six geopolitical zones (South-South, South-West, South-East, North-Center, North-West, and North-East) and two metropolitan cities (Abuja and Lagos) of Nigeria. Sociodemographic characteristics, parental alcohol use and permissiveness, friends' alcohol use, risk perceptions and beliefs were investigated as correlates of alcohol experimentation and drunkenness episodes through multilevel, mixed-effect logistic regression models. Results: The prevalence of alcohol experimentation was 34.0%, while the prevalence of drunkenness episodes was 13.4%. Results showed that male gender, family structure different from both parents' families, parental and friends' alcohol use, parental permissiveness to drink, low risk perceptions on drinking alcohol, and positive beliefs on consequences of alcohol use were associated with an increased probability of alcohol experimentation and drunkenness episodes. Family affluence and one-parent family structure were related to an increased probability of alcohol experimentation but not of drunkenness episodes. Conclusions: The majority of risk factors analyzed in this study generalize across drinking-behavior outcomes. Since the young population is dominant in Nigeria, alcohol use could become a big public health problem in the near future. High investment in adolescents' well-being by addressing the factors that contribute to drinking behavior might help to reduce the burden of the problem. Evidence-based prevention curriculum addressing knowledge, risk perceptions, beliefs on consequences of alcohol use, and parental behaviors should be implemented as widely and early as possible.

Beer consumption negatively regulates hormonal reproductive status and reduces apoptosis in Leydig cells in peripubertal rats

Beer is one of the most popular alcoholic beverages consumed by young people. Ethanol intake is associated with harmful effects to the reproductive system. Bioactive compounds present in beer may diminish the toxics effect of ethanol. However, there is still little knowledge about the effect of beer consumption on hormonal regulation of male reproduction in organisms exposed to alcohol after the peripubertal age. Therefore, the aim of this study was to determine the influence of beer intake on plasma reproductive hormones, immunolocalization of cleaved caspase-3 (casp-3), and the level of the neuronal isoform of nitric oxide synthase (nNOS) in Leydig cells (LCs) in adolescent male Wistar rats. The animals, beginning at the age of 30 days, drank beer (10% ethanol; B2 group [2 weeks' exposure] and B4 group [4 weeks' exposure]), 10% ethanol solution (CE2 group [2 weeks' exposure] and CE4 group [4 weeks' exposure]), or water (C2 group [2 weeks' exposure] and C4 group [4 weeks' exposure]). Rats drinking beer for 4 weeks showed higher phenolic acid intake compared to rats drinking beer for 2 weeks. Rats exposed to beer for 4 weeks showed decreased plasma levels of follicle-stimulating hormone (FSH) and 17β-estradiol (E2) (3.173 ng/mL and 11.49 pg/mL, respectively), compared to the CE4 (5.293 ng/mL and 43.912 pg/mL, respectively) and the C4 groups (5.002 ng/mL and 41.121 pg mL, respectively). Expression of cleaved caspase-3 in LCs was lower in the B4 group rats, compared to the CE4 group rats (ID score: 1.676 vs. 2.190). No changes in nNOS expression were observed. Beer consumption revealed a similar negative effect on hormonal regulation of male reproductive function, but lower apoptosis in LCs may be beneficial for steroidogenic activity.

Parents' drinking motives and problem drinking predict their children's drinking motives, alcohol use and substance misuse

The aim of the current study was to test the direct and indirect influence of parents' drinking motives and problem drinking on their children's drinking motives, alcohol use and substance misuse. Cross-sectional analysis of parent and child drinking patterns and motives, derived from the nationally representative Drinkaware Monitor panel survey. The sample comprised a total of 148 couples of parents and child. Path analysis revealed that children's alcohol use and substance misuse were influenced by their own drinking motives and parents' problem drinking. Parents' conformity motives were linked to their children's conformity motives. Finally, parental drinking problems mediated the effect of their coping motives on their childrens' alcohol use and substance misuse. In conclusion, parental drinking styles relate to their children's alcohol use and substance misuse through problem drinking and drinking motives.

Longitudinal Latent Cognitive Profiles and Psychosocial Well-being in Early Adolescence

PURPOSE

Engaging in exploratory risky behaviors and experiencing poor mental health during early adolescence are important markers for poor health during adulthood. Prior research suggests protective effects from cognition, but less is known about the associations between early childhood cognition and early adolescent psychosocial well-being, as identified by self-esteem, mental health, and exploratory risky behaviors. This article investigates the extent that early adolescent psychosocial well-being at the age of 11 years is associated with patterns of cognitive skills measured across the first decade of a child's life.

METHODS

We used data collected from the four follow-up sweeps of the UK Millennium Cohort Study and utilized latent profile analysis to identify three discernible cognitive profiles (n = 16,899).

RESULTS

We find cohort members in low-achieving profiles to be more likely to engage in exploratory risky behaviors-drinking, smoking, and antisocial conduct-and to have poor self-esteem and more problem behaviors, compared with their peers in high-achieving profiles. Socioeconomic and family psychosocial markers considerably attenuated these disadvantages.

CONCLUSIONS

Understanding which adolescents have adverse psychosocial well-being has implications for the prevention of chronic diseases and for clinical care and policy.

What could keep young people away from alcohol and cigarettes? Findings from the UK Household Longitudinal Study

Background

Adolescents are vulnerable to risky behaviours that are likely to co-occur. We examined whether happiness, awareness of alcohol- or smoking-related harm or the size of friendship networks would be longitudinally associated with young people’s risky behaviours.

Methods

We used available cases (N=1,729) from adolescents aged between 10 and 15 who participated in waves 2 and 3 of the UK Longitudinal Household Study that has annually collected population representative data from 40,000 UK households. The outcome variable was patterns of cigarette and alcohol use among adolescents (1= persistent non-use; 2= ex-use; 3= initiation; 4= persistent use) that we derived by tabulating current alcohol or cigarette use at waves 2 and 3. Explanatory variables were scores on participants’ perception of overall happiness, awareness of harm due to alcohol and cigarette use, and supportive friendship network size, collected at wave 2. Covariates were participants’ sex, age, base level of self-reported health status, reported religious affiliation, and household social position. All estimates were corrected for the complex survey design and non-response. Multinomial logistic regression was used to test assumed associations by taking persistent cigarette and alcohol use as the reference category.

Results

Findings showed higher happiness scores were longitudinally associated with adolescents’ persistent non-use (RRR=1.06, 95% CI=1.01-1.13). Awareness of alcohol or cigarette use-related harm was longitudinally associated with persistent non-use (RRR=1.24, 95% CI 1.15-1.35) as well as initiation of alcohol or cigarette use (RRR=1.21, 95% CI=1.11-1.32).

Conclusion

Joint interventions to promote happiness and harm awareness could help young adolescents from engaging with drinking alcohol or smoking cigarettes.
