Adolescent alcohol use

Florian Labhart, Michael Livingston, Rutger Engels, Emmanuel Kuntsche
BACKGROUND AND AIMS: The threshold of 4+/5+ drinks per occasion has been used for decades in alcohol research to distinguish between non-risky vs. risky episodic drinking. However, no study has assessed the validity of this threshold using event-level data. This study aimed to determine the optimal thresholds for the detection of five acute alcohol-related consequences (hangover, blackout, risky sex, fights and injury) using data from two event-level studies. DESIGN: An event-level study to assess the ability to use the number of drinks consumed to discriminate between nights with and without consequences using the area under the receiver operating characteristic (AUROC) curve...

Periodic episodes of excessive alcohol consumption ("binge drinking") occur frequently among adolescents, and early binge drinking is associated with an increased risk of alcohol use disorders later in life. The prefrontal cortex (PFC) undergoes significant development during adolescence and hence may be especially susceptible to the effects of binge drinking. In humans and in animal models, adolescent alcohol exposure is known to alter PFC neuronal activity and produce deficits in PFC-dependent behaviors such as decision making, response inhibition, and working memory...

BACKGROUND: An increasingly recognised prevention approach for substance use entails a reduction in risk factors, and the enhancement of promotive, or protective factors in individuals and the environment surrounding them during their growth and development. METHODS: This exploratory study evaluated the effect of potential risk and protective factors associated with family management relating to adolescent substance use in South Africa. Exploratory analysis and cumulative odds ordinal logistic regression modelling was performed on the data, while controlling for the influence of demographic and socio-economic characteristics on adolescent substance use...

Nicotine and alcohol are often co-abused. Adolescence is a vulnerable period for the initiation of both nicotine and alcohol use, which can lead to subsequent neurodevelopmental and behavioral alterations. It is possible that during this vulnerable period, use of one drug leads to neurobiological alterations that affect subsequent consumption of the other drug. The aim of the present study was to determine the effect of nicotine exposure during adolescence on ethanol intake, and the effect of these substances on brain gene expression...

Although impulsivity and sensation seeking have been consistently associated with substance use, few studies have analyzed the relationship between changes in these variables and substance use in early adolescents. The aim of this study was to identify trajectories of impulsivity and sensation seeking and explore their relationship with substance use and heavy drinking. A total of 1342 non-user adolescents (53.6% males; mean age = 12.98, SD = 0.50) annually completed the Barratt Impulsiveness Scale, the Zuckerman's Impulsive Sensation Seeking scale and a delay discounting task, over a total period of three years...

BACKGROUND: Abnormalities in reward circuit function are considered a core feature of addiction. Yet, it is still largely unknown whether these abnormalities stem from chronic drug use, a genetic predisposition, or both. METHODS: In the present study, we investigated this issue using a large sample of adolescent children by applying structural equation modeling to examine the effects of several dopaminergic polymorphisms of the D1 and D2 receptor type on the reward function of the ventral striatum (VS) and orbital frontal cortex (OFC), and whether this relationship predicted the propensity to engage in early alcohol misuse behaviors at 14 years of age and again at 16 years of age...

Adolescent alcohol use is related to disinhibition traits and family environments. However, research is scarce on whether these factors predict alcohol use trajectories distally, from early adolescence into early adulthood. We examined whether sensation seeking and parenting environments in early adolescence predicted adolescents' alcohol use trajectories proximally (middle-adolescence) and distally (early adulthood). Using four waves of data from 345 adolescents (51.3% female; 80% white) and their primary caregivers, we estimated adolescents' alcohol use trajectories and examined variability in these by sensation seeking and parental control...

PROBLEM: Health-risk behaviors contribute to the leading causes of morbidity and mortality among youth and adults in the United States. In addition, significant health disparities exist among demographic subgroups of youth defined by sex, race/ethnicity, and grade in school and between sexual minority and nonsexual minority youth. Population-based data on the most important health-related behaviors at the national, state, and local levels can be used to help monitor the effectiveness of public health interventions designed to protect and promote the health of youth at the national, state, and local levels...

CLINICIAN'S CAPSULE What is known about the topic? Emergency department (ED) visits for adolescent alcohol-related concerns offer the opportunity for early intervention; however, the underlying alcohol problem generally remains unaddressed. What did this study ask? What are ED physicians' perceptions regarding adolescent alcohol use and ED-based intervention? What are their current intervention practices? What did this study find? While the majority of ED physicians feel the responsibility to address problematic adolescent alcohol use, interventional practices are unstandardized and lacking...

Using a large and nationally representative sample, we examined how adolescents' 5-HTTLPR genotype and perceived parenting quality independently and interactively associated with trajectories of alcohol use from early adolescence to young adulthood and whether/how gender may moderate these associations. The sample for this study included 13,749 adolescents (53.3% female; 56.3% non-Hispanic White, 21.5% Black, 16.0% Hispanic, and 6.1% Asian) followed prospectively from adolescence to young adulthood. Using growth mixture modeling, we identified four distinct trajectories of alcohol use (i...

Background and objectives Research has shown an increased prevalence of substance use among adolescents in countries in Sub-Saharan Africa. Peer affiliation, bullying, and psychological stress are significantly associated with substance use. This study empirically tested theoretical frameworks linking peer affiliation, bullying victimization, loneliness and substance use (specifically tobacco or alcohol use) among adolescents. Materials and methods Data were obtained from the 2009 Malawi Global School-based Health Survey (GSHS) with a representative sample of 2359 students aged 13-17 years in Malawi, Sub-Saharan Africa...

BACKGROUND: Adolescence is a peak time for uptake of both tobacco and marijuana (dual use). This study aimed to identify clusters of lifetime tobacco and marijuana use patterns and associated risk factors, and to determine whether dual tobacco and marijuana use is uniquely associated with greater risk than use of either tobacco or marijuana alone. METHOD: High school students participated in a survey during Fall 2014 (N = 976; 68% Hispanic; 57% parental education < high school)...

Binge drinking appears to be a risk factor, facilitator, and method of suicidal and non-suicidal self-injury for some American Indian (AI) youth. We examined characteristics, patterns, and motivations for binge use among AI adolescents (N = 69; 10-19 years-old) who recently engaged in binge drinking. The majority used alcohol alone (53.7%) or a combination of alcohol and marijuana (31.3%) for their binge event. Gender differences emerged with boys more severely affected than girls. Forty-seven percent reported lifetime suicidal thoughts...

BACKGROUND: There is considerable evidence that exposure to alcohol marketing increases the likelihood of adolescents initiating and engaging in alcohol consumption. There is a paucity of research, however, specifically examining industry generated alcohol marketing occurring on social media/networking platforms. OBJECTIVE: The purpose of this investigation was to analyze the content of promotional advertisements by alcohol brands on Instagram. METHODS: For a 30-day period, Instagram profiles of 15 distinct alcohol brands were examined...

BACKGROUND: Parental provision of alcohol to their underage child has been associated with risky adolescent drinking. While parents' belief in the appropriateness of providing their child with alcohol may influence their provision behaviors, research into the factors associated with this belief is lacking. OBJECTIVES: This study sought to identify the factors associated with parents' belief in the appropriateness of providing alcohol to their underage child. METHODS: Western Australian parents of 12-17 year olds (n = 443) completed an online survey assessing their drinking habits, alcohol provision behaviors, alcohol-related beliefs and attitudes, their child's alcohol consumption, and demographics...

OBJECTIVE: We investigated how associations between social and situational characteristics (number of people, adult supervision, group gender composition, group age composition, ease of alcohol access, and weekend) and underage drinking are moderated by the specific locations in which drinking occurs. METHOD: Using a case-crossover design and retrospective surveys, a sample of 385 adolescents (mean age = 16.5 years; 47.3% female) from 24 mid-size California cities reported the last time they drank alcohol in a specific location (restaurant, outdoors, home) and the last time they were at the same type of location without drinking, as well as characteristics of each drinking and nondrinking event (N = 1,096 events)...

OBJECTIVE: The purpose of this study was to quantify the persistence of immediate changes in adolescents' alcohol-related beliefs associated with exposure to alcohol advertising. METHOD: Middle school students (N = 606) carried handheld devices for 14 days and logged all of their exposures to alcohol advertisements as they naturally occurred. Perceptions of the typical person one's age who drinks ("prototype perceptions") and perceived norms regarding alcohol use were assessed after each exposure to advertising and at random prompts issued daily throughout the assessment period...

OBJECTIVE: The relationships between depressive symptoms and alcohol use among maltreated youth have been well documented. However, the direction of these associations remains unclear. Two prevalent but contrasting perspectives on these associations-the self-medication and impaired-functioning hypotheses-have each received extensive support. The present study aims to test these hypotheses and to reconcile these theoretical and empirical inconsistencies by advancing a third integrative conceptualization, the bidirectional hypothesis, which considers developmental timing in the transactional associations between maltreated youth's depressive symptoms and alcohol use over time...
