Adverse adult consequences of different alcohol use patterns in adolescence: an integrative analysis of data to age 30 years from four Australasian cohorts

Beyond the Laws: Parental Monitoring, Perceived Acceptability of Underage Drinking and Alcohol Use Among Belgian Youth

Parental monitoring behaviors are negatively associated with adolescent substance use. Yet, the processes explaining these associations are still unclear. The current study examined adolescents' knowledge of minimum legal drinking age laws and their perceived acceptability of underage drinking as potential mediators of the links between parental monitoring behaviors and youth alcohol use. The sample included 1154 Belgian adolescents (Mage = 16.34, SD = 1.33; 71% girls), who were recruited in Wallonia (54.9%) and in Flanders (45.1%). Path analyses revealed that higher parental rule setting, but not solicitation, was related to lower alcohol use. Acceptability of underage drinking mediated this link, but not knowledge of the laws. Results suggest that beyond laws regulating the minimum legal drinking age, alcohol use prevention programs should consider the importance of parental rule setting and youth's perceived acceptability of underage drinking.

Adverse childhood experiences, mental distress, self-harm and suicidality, and cumulative HIV risk by sex in Lesotho

BACKGROUND

Adverse childhood experiences (ACEs) have been understudied in low- and middle-income countries, especially in sub-Saharan Africa.

OBJECTIVES, PARTICIPANTS, SETTING

We explored associations between mental distress, self-harm or suicidality, and HIV risk and individual and cumulative ACEs (sexual, emotional, and physical violence; witnessing community and interparental violence; orphanhood) among youth aged 13-24 in Lesotho.

METHODS

Multivariable logistic regressions stratified by sex using nationally representative 2018 Lesotho Violence Against Children and Youth Survey (nfemale = 7101; nmale = 1467) data.

RESULTS

Over 75 % of males and females experienced at least 1 ACE. Among males, physical and community violence were significantly associated with mental distress; orphan status and emotional violence was associated with self-harm/suicidality. Males who witnessed interparental violence had higher odds of disclosing 2 types and 3 or more types of HIV risk versus none. Among females, being a double orphan and having experienced sexual, emotional, physical, community, and interparental violence were significantly associated with mental distress and any self-harm/suicidality in both models. Females who experienced physical violence had higher odds of disclosing 3 or more risk types versus no risk. Statistically significant associations emerged between cumulative ACEs and mental distress, self-harm/suicidality, and higher levels of HIV risk for both males and females.

CONCLUSIONS

Differential patterns of associations between ACEs and mental health problems and HIV risk emerged by sex. Scalable, integrated individual and community efforts to prevent ACEs, provide mental health supports, and encourage safer sexual behaviors among those exposed are needed and could benefit youth in Lesotho.

Adolescent alcohol and cannabis use and early adulthood educational attainment in the 1986 Northern Finland birth cohort study

BACKGROUND

Heavy alcohol and cannabis use during adolescence have been previously described as risk factors not only for morbidity in adulthood, but also social problems including adversities in educational attainment. Attempts to consider overlapping risk factors and confounders for these associations are needed.

METHODS

Using weighted multivariable models, we examined prospective associations between age at first drink (AFD), age at first intoxication (AFI), frequency of alcohol intoxication, as well as self-reported alcohol tolerance (i.e., number of drinks needed for the subjective experience of intoxication), and lifetime cannabis use at age 15/16 years with subsequent educational attainment obtained from comprehensive registers until age 33 in the Northern Finland Birth Cohort 1986 (6,564 individuals, 49.1% male). Confounding variables including sex, family structure (intact vs. non-intact), maternal and paternal education level, behavioural/emotional problems in school at age 7/8 years, having a history of illicit substance use in adolescence, having any psychiatric diagnosis before age 16, and parental psychiatric diagnoses, were adjusted for.

RESULTS

In this large birth cohort study with a 17-year follow-up, younger age at first intoxication, higher frequency of alcohol intoxication, and high self-reported alcohol tolerance at age 15/16 years were associated with poorer educational outcomes by the age of 33 years. These associations were evident regardless of potential confounders, including parental education and childhood behavioural/emotional problems. The association between adolescent cannabis use and educational attainment in adulthood was no longer statistically significant after adjusting for confounders including frequency of alcohol intoxication at age 15/16.

CONCLUSIONS

Assessments of age of first alcohol intoxication, high self-reported alcohol tolerance and frequency of intoxication during adolescence should be included when implementing screening strategies aimed at identifying adolescents at risk for subsequent social problems.

Associations of adolescent substance use and depressive symptoms with adult major depressive disorder in the United States: NSDUH 2016-2019

BACKGROUND

Few studies have focused on the associations of adolescent substance use and depressive symptoms with adult major depressive disorder (MDD).

METHODS

Data from 168,859 adults, among which, 15,959 had experienced MDD in the past year, as indicated by a major depressive episode (MDE) marked by MDD symptoms, were from the 2016-2019 National Surveys on Drug Use and Health. Weighted multivariable logistic regression (MLR) analyses were used to determine the associations.

RESULTS

The overall MDD prevalence was 7.2 %, whereas the prevalence for adults without early onset depressive symptoms prior to age 18 was 4.6 %. Variable cluster analysis revealed that adolescent use of alcohol, cigarettes, marijuana, cocaine, hallucinogen use, and inhalants prior to age 18 were in one cluster. MLR analyses showed that the presence of depressive symptoms prior to age 18 was the major risk factor for MDD, while adolescent use of alcohol, marijuana, and inhalants prior to age 18 were associated with increased odds of MDD (p < 0.05) both in the whole data and the subset of adults without depressive symptoms prior to age 18. Adolescent use of cocaine prior to age 18 were associated with MDD only in the whole data, whereas adolescent smokeless tobacco use was associated with MDD only in those without depressive symptoms prior to age 18.

CONCLUSIONS

These findings highlight the comorbid early substance use and depressive symptoms during adolescence with adult MDD. Intervention strategies should simultaneously address early-onset substance use and depressive symptoms prior to age 18.

Orthodontic Patients with Poor Oral Health-Related Quality of Life are More Likely to Have Emotional Distress: A Cross-Sectional Study

Objective

This study aims to investigate the relationship between oral health-related quality of life (OHRQoL) and emotional distress (ED), including anxiety and depression, in orthodontic patients.

Methods

A cross-sectional study was conducted involving 603 orthodontic patients, consisting of 401 females (66.5%) with a mean age of 24.15 ± 7.72 and 202 males (33.5%) with a mean age of 24.16 ± 7.72. A questionnaire containing questions of demographic information, the Oral Health Impact Profile (OHIP-14) and the Huaxi emotional-distress index (HEI) was employed to assess OHRQoL and ED. According to the HEI score, the respondents were divided into ED group (HEI > 8) and non-ED group (HEI ≤ 8). Data were analyzed using Kolmogorov-Smirnov test, Mann-Whitney test and logistic regression analysis with the significance level set at p < 0.05.

Results

The prevalence of poor OHRQoL and ED of the study sample was 28.4% and 19.57%, respectively. There was a significantly higher prevalence of ED among poor OHRQoL patients (35.67%) compared to those with good OHRQoL (13.19%) (p < 0.001). Poor OHRQoL and risky drinking behavior addressed higher significant correlation with ED patients than non-ED patients (p < 0.05). There were no statistical differences in other factors such as gender, age, and appliance type (p > 0.05). Poor OHRQoL orthodontic patients were at a higher risk of suffering from anxiety and depression compared to those with good OHRQoL (age-risky drinking behavior-sex-adjusted: OR = 4.00; all p < 0.001).

Conclusion

Oral health-related quality of life (OHRQoL) is related to emotional stress. Namely, patients with poor OHRQoL are more likely to experience anxiety and depression. As a result, orthodontists should consistently assess the emotional well-being and OHROoL of patients over the treatment course for better treatment outcomes.

A latent class approach to understanding patterns of emotional and behavioral problems among early adolescents across four low- and middle-income countries

Early adolescents (ages 10-14) living in low- and middle-income countries have heightened vulnerability to psychosocial risks, but available evidence from these settings is limited. This study used data from the Global Early Adolescent Study to characterize prototypical patterns of emotional and behavioral problems among 10,437 early adolescents (51% female) living in the Democratic Republic of Congo (DRC), Malawi, Indonesia, and China, and explore the extent to which these patterns varied by country and sex. LCA was used to identify and classify patterns of emotional and behavioral problems separately by country. Within each country, measurement invariance by sex was evaluated. LCA supported a four-class solution in DRC, Malawi, and Indonesia, and a three-class solution in China. Across countries, early adolescents fell into the following subgroups: Well-Adjusted (40-62%), Emotional Problems (14-29%), Behavioral Problems (15-22%; not present in China), and Maladjusted (4-15%). Despite the consistency of these patterns, there were notable contextual differences. Further, tests of measurement invariance indicated that the prevalence and nature of these classes differed by sex. Findings can be used to support the tailoring of interventions targeting psychosocial adjustment, and suggest that such programs may have utility across diverse cross-national settings.

When Substance Use Is Underreported: Comparing Self-Reports and Hair Toxicology in an Urban Cohort of Young Adults

OBJECTIVE

Large-scale epidemiological research often uses self-reports to determine the prevalence of illicit substance use. Self-reports may suffer from inaccurate reporting but can be verified with objective measures. This study examined the following: the prevalence of illicit and non-medical substance use with self-reports and hair toxicology, the convergence of self-reported and objectively quantified substance use, and the correlates of under- and overreporting.

METHOD

The data came from a large urban cohort study of young adults (n = 1,002, mean age = 20.6 years, 50% female). The participants provided 3 cm of hair (covering the previous 3 months) and reported their illicit and non-medical substance use and their sociodemographic, psychological, and behavioral characteristics. Hair toxicology analyses targeted cannabinoids, ketamine, opiates/opioids, stimulants including 3,4-methylenedioxymethamphetamine, and relevant metabolites.

RESULTS

Self-reports underestimated the prevalence of most substances by 30% to 60% compared to hair tests. The average detection ratio (hair test/self-report) was 1.50. Hair tests were typically more sensitive than self-reports. Underreporting was associated with a low level of that substance in hair. Self-reported delinquency and psychopathology were correlated with an increased likelihood of concordant positive self-reports and hair tests compared to underreporting. Overreporting was associated with infrequent self-reported use.

CONCLUSION

Our study suggests that self-reports underestimate young adults' exposure to illicit substances and non-medical use of prescription drugs. Consequently, estimates of associations between substance use and risk factors or outcomes are likely biased. Combining self-reports with hair tests may be most beneficial in study samples with occasional substance use. Researchers can use specific factors (eg, detection ratios) to adjust prevalence estimates and correlations based on self-reports.

Age, period and cohort effects on alcohol-related risky behaviours in Australia from 2001 to 2016

AIMS

The aim of this study is to examine age, period and birth cohort trends in the prevalence of any alcohol-related risky behaviour and to compare these trends between men and women.

DESIGN AND SETTING

We used an age-period-cohort analysis of repeated cross-sectional survey data from the Australian National Drug Strategy Household Survey from 2001 to 2016.

PARTICIPANTS

Participants were 121 281 people aged 14-80 years who reported consuming alcohol in the past 12 months.

MEASUREMENTS

Any risky behaviour undertaken while under the influence of alcohol in the past 12 months (e.g. operating a motor vehicle) was measured: male or female.

FINDINGS

Controlling for age and cohort, cubic spline models showed that any alcohol-related risky behaviour declined with time among participants who consumed alcohol [2016 versus 2007 rate ratio (RR) = 0.80, 95% confidence interval (CI) = 0.76-0.84]. Risky behaviour peaked in the 1954 birth cohort (1954 versus 1971 RR = 1.42, 95% CI = 1.30-1.55) and then steadily declined with more recent birth cohorts (2002 versus 1971 RR = 0.32, 95% CI = 0.27-0.39). Risky behaviour peaked at age 21 years, followed by steady decline and stabilization at approximately age 70 years. Males were overall twice as likely as females to report alcohol-related risky behaviour (RR = 2.10, 95% CI = 1.84-2.39), but this effect was smaller in cohorts born after 1980 [1980 prevalence rate ratios (PRR) = 2.09, 95% CI = 1.81-2.43; 2002 PRR = 1.31, 95% CI = 1.03-1.68].

CONCLUSIONS

Alcohol-related risky behaviour in Australia has declined generally since 2001, with rates for recent cohorts having the sharpest decline. Risky behaviour remains most prevalent in young adults, and the male-female gap in risky behaviour is closing for more recent birth cohorts. These trends are consistent with alcohol consumption trends observed in Australia and world-wide.

Neurocognitive effects of binge drinking on verbal episodic memory. An ERP study in university students

Background: Verbal memory may be affected by engagement in alcohol binge drinking during youth, according to the findings of neuropsychological studies. However, little is known about the dynamics of the neural activity underlying this cognitive process in young, heavy drinkers. Aims: To investigate brain event-related potentials associated with cued recall from episodic memory in binge drinkers and controls. Methods: Seventy first-year university students were classified as binge drinkers (32: 17 female) or controls (38: 18 female). The participants completed a verbal paired associates learning task during electroencephalogram (EEG) recording. ERPs elicited by old and new word pairs were extracted from the cued-recall phase of the task by using Principal Component Analysis. Subjects also performed a standardized neuropsychological verbal learning test. Results: Two of the three event-related potentials components indicating old/new memory effects provided evidence for anomalies associated with binge drinking. The old/new effects were absent in the binge drinkers in the two subsequent posterior components, identified with the late parietal component and the late posterior negativity The late frontal component revealed similar old/new effects in both groups. Binge drinkers showed similar behavioural performance to controls in the verbal paired associates task, but performed poorly in the more demanding short-term cued-recall trial of a neuropsychological standardized test. Conclusion: Event-related potentials elicited during a verbal cued-recall task revealed differences in brain functioning between young binge drinkers and controls that may underlie emergent deficits in episodic memory linked to alcohol abuse. The brain activity of binge drinkers suggests alterations in the hippocampal - posterior parietal cortex circuitry subserving recognition and recollection of the cue context and generation of the solution, in relation to verbal information shallowly memorised.

Integrated care – panacea or white elephant? A review of integrated care approaches in Australia over the past two decades

Purpose

Integrated care is widely supported as a means of improving treatment outcomes for people with co-occurring mental health and substance use disorders. Over the past two decades, Australian state and federal governments have identified integrated care as a policy priority and invested in a number of research and capacity building initiatives. This study aims to examine Australian research evaluating the effectiveness of integrated treatment approaches to provide insight into implications for future research and practice in integrated treatment.

Design/methodology/approach

This narrative review examines Australian research evaluating empirical evidence of the effectiveness of integrated treatment approaches within specific populations and evidence from initiatives aimed at integrating care at the service or system level.

Findings

Research conducted within the Australian context provides considerable evidence to support the effectiveness of integrated approaches to treatment, particularly for people with high prevalence co-occurring disorders or symptoms of these (i.e. anxiety and depression). These have been delivered through various modalities (including online and telephone-based services) to improve health outcomes in a range of populations. However, there is less evidence regarding the effectiveness of specific models or systems of integrated care, including for more severe mental disorders. Despite ongoing efforts on behalf of the Australian government, attempts to sustain system-level initiatives have remained hampered by structural barriers.

Originality/value

Effective integrated interventions can be delivered by trained clinicians without requiring integration at an organisational or structural level. While there is still considerable work to be done in terms of building sustainable models at a system level, this evidence provides a potential foundation for the development of integrated care models that can be delivered as part of routine practice.

Age at first alcohol-related hospital separation or emergency department presentation and rate of re-admission: A retrospective data linkage cohort of young Australians

INTRODUCTION

Alcohol is a leading risk factor for death and disease in young people. We compare age-specific characteristics of young people who experience their first ('index') alcohol-related hospitalisation or emergency department (ED) presentation, and whether age at index predicts 12-month rates of readmission.

METHODS

We used a retrospective linked-data cohort of 10,300 people aged 12-20 years with an index alcohol-related hospital and/or ED record in New South Wales, Australia from 2005 to 2013. Age group (early adolescent [12-14 years], late adolescent [15-17 years], young adult [18-20 years]) and diagnosis fields were used in logistic regression analyses and to calculate incidence rates with adjustment for year of index event, sex, socioeconomic disadvantage and residence remoteness.

RESULTS

People who experienced their index event in early adolescence (adjusted relative risk ratio [ARRR] 0.45 [95% confidence interval 0.39, 0.52]) or late adolescence (ARRR 0.82 [0.74, 0.90]) were less likely to be male compared to young adults. Early adolescents (ARRR 0.60 [0.51, 0.70]) and late adolescents (ARRR 0.84 [0.76, 0.93]) were less likely to have a hospitalisation index event. Early adolescents (adjusted incidence rate ratio 1.40 [1.15, 1.71]) and late adolescents (adjusted incidence rate ratio 1.16 [1.01, 1.34]) were more likely than young adults to have a subsequent 12-month non-poisoning injury ED presentation.

DISCUSSION AND CONCLUSIONS

We identified preventable hospital events in young people who have previously experienced an alcohol-related ED presentation or hospitalisation, with age-specific characteristics and outcomes that can be used to inform future health policy and service planning.

Violence Exposure, Self-Reported Mental Health Concerns and Use of Alcohol and Drugs for Coping among Youth in the Slums of Kampala, Uganda

This study aimed to a) compute the prevalence of violence exposure types, polyvictimization, and self-reported depression, anxiety, and using substances to cope among youth ages 12 to 18 years living on the streets or in the slums of Kampala, Uganda, (b) examine the independent associations among orphan status, violence exposure types, and self-reported mental health concerns, and c) explore the association between polyvictimization and mental health concerns. Data are from a 2014 cross-sectional survey of service-seeking youth ages 12 to 18 years (N = 1134) in Kampala, Uganda. Violence exposure types explored in this study were: witnessing family physical violence, direct physical abuse by a parent, any rape history, and physical dating violence. We used descriptive statistics and multivariable logistic regression to test study objectives. Over half of the sample (60.5%) reported experiencing at least one type of violence exposure; many youth endorsed self-reported depression (57.8%), anxiety (76.8%), and substance use to cope (37.0%). Exposure to violence was associated with higher odds for self-reported depression, anxiety, and using substances to cope. These findings underscore the urgent need to implement evidence-based interventions among this young, underserved population and their families to prevent violence, improve mental health outcomes, and promote resilience.

Relationship between Prosocial Behaviours and Addiction Problems: A Systematic Review

The relationship of addiction problems with other pathologies or with different problematic factors has often been studied by psychology. Positive psychology is also currently approaching to these problems and their relationship with positive factors, such as prosocial behaviours. The purpose of this research is to carry out a systematic review of the scientific literature that has studied this relationship from 1900 to 2020. After the screening process with the inclusion and exclusion criteria, a total of 15 articles were selected. The main characteristics found in this relationship and the problems or limitations of investigations that have found relationships other than the mainstream, which show a negative relationship between prosocial behaviours and addiction problems, are discussed.

Integrative data analysis of self-efficacy in 4 clinical trials for alcohol use disorder

BACKGROUND

Self-efficacy has been proposed as a key predictor of alcohol treatment outcomes and a potential mechanism of success in achieving abstinence or drinking reductions following alcohol treatment. Integrative data analysis, where data from multiple studies are combined for analyses, can be used to synthesize analyses across multiple alcohol treatment trials by creating a commensurate measure and controlling for differential item functioning (DIF) to determine whether alcohol treatments improve self-efficacy.

METHOD

The current study used moderated nonlinear factor analysis (MNLFA) to examine the effect of treatment on self-efficacy across four different treatment studies (N = 3720; 72.5% male, 68.4% non-Hispanic white). Self-efficacy was measured using the Alcohol Abstinence Self-Efficacy Scale (AASE) in the COMBINE Study (n = 1383) and Project MATCH (n = 1726), and the Drug Taking Confidence Questionnaire (DTCQ) in two studies of Telephone Continuing Care (TEL Study 1: n = 303; TEL Study 2: n = 212). DIF was examined across time, study, treatment condition, marital status, age, and sex.

RESULTS

We identified 12 items from the AASE and DTCQ to create a commensurate measure of self-efficacy using MNLFA. All active treatments, including cognitive-behavioral treatment, a combined behavioral intervention, medication management, motivation enhancement treatment, telephone continuing care, twelve-step facilitation, and relapse prevention, were associated with significant increases in self-efficacy from baseline to posttreatment that were maintained for up to a year. Importantly, treatment as usual in community settings, which consisted of weekly group therapy that included addiction counseling and twelve-step recovery support, was not associated with significant increases in self-efficacy.

CONCLUSIONS

Alcohol self-efficacy increases following treatment and numerous evidence-based treatments are associated with significant increases in self-efficacy, which are maintained over time. Community treatment that focuses solely on addiction counseling and twelve-step support may not promote increases in self-efficacy.

The information capacity of adolescent alcohol consumption indicators along a continuum of severity: A cross-national comparison of sixteen Central and Eastern European countries

BACKGROUND

There is high variability between European countries in prevalence levels of various alcohol consumption forms. The informational value of adolescent's alcohol consumption indicators remains an issue. The present study aimed to examine information capacity and measurement invariance of different alcohol consumption indicators in adolescents coming from countries of the former Soviet (Eastern) Bloc in Central and Eastern Europe (CEE).

METHODS

Data of 15-year-old adolescents who reported to have had consumed alcohol at least once in their lifetime were analysed. Data were collected in sixteen CEE countries, as part of the 2013/2014 Health Behavior in School-aged Children (HBSC) study wave. Four binary items were selected for the analyses and measured the presence (vs. absence) of alcohol consumption in the last 30 days, lifetime drunkenness, weekly drinking frequency and binge drinking on a typical occasion. Multiple group confirmatory factor analysis and item response theory analysis were used.

RESULTS

In most of the included countries, alcohol consumption in the last 30 days and lifetime drunkenness were indicative for lower severity levels, while binge drinking and weekly drinking frequency were informative at higher severity levels of alcohol use. A low proportion of the estimated intercepts and factor loadings were non-invariant which indicated approximate cross-national invariance of these indicators.

CONCLUSIONS

Adolescent alcohol consumption indicators are informative for different severity levels and provide a cross-nationally invariant measurement. However, diverging drinking cultures in the CEE regions was suggested by different indicators with the highest discrimination capacity at the lower and the higher ends of the continuum severity.

Parenting and Home Environment in Childhood and Adolescence and Alcohol Use Disorder in Adulthood

PURPOSE

Parenting is a modifiable factor affecting the development of alcohol use disorder (AUD); however, the persistence of this effect into adulthood remains poorly understood. This study aimed to explore the longitudinal relationship between positive parenting and AUD in adulthood.

METHODS

Data were gathered from the Christchurch Health and Development Study (CHDS), a birth cohort of 1,265 children born in Christchurch (New Zealand) in mid-1977. Positive parenting was quantified to age 16, and included the extent to which cohort members self-reported: high scores on measures of maternal and paternal care; low scores on a measure of maternal and paternal overprotection; high scores on a measure of parental attachment; low scores on a measure of parental intimate partner violence; and occasional or no use of physical punishment. Outcome measures were AUD incidence and symptoms at ages 15-35, with potential confounding factors and time-dynamic covariates included.

RESULTS

There was a significant association between positive parenting and AUD outcomes, with higher levels of positive parenting associated with a lower incidence of AUD and AUD symptoms. Controlling for confounding factors reduced the association between positive parenting and AUD outcomes, but they remained statistically significant. Adjustment for mental health, life stress, and employment reduced the magnitude of the association between positive parenting and alcohol outcomes to statistical nonsignificance.

CONCLUSIONS

Parenting factors in childhood and adolescence are linked to AUD outcomes in adulthood, as well as mental health, substance use, and life stress. Investment in positive parenting in adolescence may reduce AUD and associated harms in adulthood.

Alcohol and Brain Development in Adolescents and Young Adults: A Systematic Review of the Literature and Advisory Report of the Health Council of the Netherlands

Young people, whose brains are still developing, might entail a greater vulnerability to the effects of alcohol consumption on brain function and development. A committee of experts of the Health Council of the Netherlands evaluated the state of scientific knowledge regarding the question whether alcohol negatively influences brain development in young people. A systematic literature search for prospective studies was performed in PubMed and PsychINFO, for longitudinal studies of adolescents or young adults ranging between 12 and 24 y of age at baseline, investigating the relation between alcohol use and outcome measures of brain structure and activity, cognitive functioning, educational achievement, or alcohol use disorder (AUD), with measures at baseline and follow-up of the outcome of interest. Data were extracted from original articles and study quality was assessed using the Newcastle-Ottawa Scale. A total of 77 studies were included, 31 of which were of sufficient quality in relation to the study objectives. There were indications that the gray matter of the brain develops abnormally in young people who drink alcohol. In addition, the more often young people drink or the younger they start, the higher the risk of developing AUD later in life. The evidence on white matter volume or quality, brain activity, cognitive function, and educational achievement is still limited or unclear. The committee found indications that alcohol consumption can have a negative effect on brain development in adolescents and young adults and entails a risk of later AUD. The committee therefore considers it a wise choice for adolescents and young adults not to drink alcohol.

Total Keratin-18 (M65) as a Potential, Early, Non-Invasive Biomarker of Hepatocyte Injury in Alcohol Intoxicated Adolescents-A Preliminary Study

BACKGROUND

Underage drinking is associated with health risk behaviors. Serum keratin-18 (CK18) levels are increased in liver diseases and may be biomarkers of outcome. The purpose of this study was to determine if the total CK18 (M65) or caspase-cleaved CK18 (M30) levels were different in adolescents admitted to hospital because of alcohol intoxication and controls with excluded liver diseases.

METHODS

A prospective study included 57 adolescents after alcohol use and 23 control subjects. The concentrations of M30 and M65 in the serum samples were evaluated using an enzyme-linked immunosorbent assay.

RESULTS

The median age was 15 (14-17) years and 49% were male. There were significant differences in M65 levels between the study and control groups (p = 0.03). The concentrations of M30 and M65 were insignificant in adolescents divided into subgroups according to blood alcohol concentrations (BAC). Significant positive correlations were found between BAC and M65 levels (p = 0.038; r = 0.3). In receiver operating characteristic (ROC) analysis M65 (cut-off = 125.966 IU/l, Se = 70.2%, Sp = 43.5%) allowed to differentiate between patients with and without alcohol intoxication (AUC = 0.66, p = 0.03).

CONCLUSION

M65 appears to be a promising non-invasive biomarker of hepatocyte injury during alcohol intoxication in adolescents. Moreover, a higher concentration of M65 may indicate early organ injury before the increase in the activity of liver enzymes, alanine aminotransferase (ALT) and aspartate aminotransferase (AST).

Drinking frequency matters: links between consumption pattern and implicit/explicit attitudes towards alcohol

RATIONALE

Attitudes towards alcohol constitute a central factor to predict future consumption. Previous studies showed that young adults with risky alcohol consumption present positive implicit and explicit attitudes towards alcohol.

OBJECTIVES

It appears crucial to disentangle the relationship between specific consumption patterns (e.g., binge drinking or moderate daily drinking) and these alcohol-related attitudes.

METHODS

We compared implicit/explicit positive attitudes towards alcohol among 101 university students distributed in 4 groups [control low-drinking participants (CP), daily drinkers (DD), low binge drinkers (LBD), high binge drinkers (HBD)] differing regarding alcohol consumption profile, to explore the impact of consumption characteristics on alcohol-related attitudes. Participants performed a visual version of the Implicit Association Test (evaluating implicit attitudes towards alcohol), followed by self-reported measures of explicit alcohol-related attitudes and expectancies.

RESULTS

HBD and DD (but not LBD) presented stronger implicit positive attitudes towards alcohol than CP. All drinkers explicitly considered alcohol consumption as pleasant, but only DD qualified it as something good.

CONCLUSION

Beyond and above the quantity consumed and the presence of binge drinking habits, consumption frequency appears as a central factor associated with high implicit/explicit positive attitudes towards alcohol in young drinkers. This underlines the need to consider this factor not only in future studies exploring implicit/explicit attitudes but also in the development of prevention and intervention campaigns in youth.

The efficacy of a targeted PREVENTION programme for addictive behaviour (PREVENTURE) among vulnerable ADOlescents in France - study procotol

Background

Alcohol use is a major public health challenge in France, where at the age of 17 half the young people report an episode of severe alcohol intoxication in the month preceding the survey. Numerous prevention programmes have a general objective, but in adolescence individual vulnerabilities towards addictions differ significantly with personality traits. Prevention targeting personality traits enables work on risk factors for addictive behaviours, and has shown genuine efficacy.

Among existing programmes, PREVENTURE has shown an effect on the reduction in alcohol consumption by targeting four personality traits: impulsivity, sensation-seeking, negative thoughts and anxiety. This programme has been tested on samples recruited in adolescent populations in school environments, identifying adolescents at risk, but it has not been tested on a more targeted recruitment of adolescents seen in consultation.

Methods

The main hypothesis of this study is that the targeted prevention programme PREVENTURE will have an impact on the prevalence of binge-drinking episodes. The secondary hypotheses explore other factors such as associated substance use, anxiety and depression, as well as the acceptability of the programme. This article presents the study protocol of “PREVADO” study.

We intend to assess the impact of the targeted intervention programme PREVENTURE on the prevalence of binge-drinking episodes among adolescents aged 14 to 17 years consulting in one of the participating centres or referred by a school doctor. The study will be prospective, randomised, controlled and open-label, and will comprise an intervention group and a control group.

The adolescents will then be followed and assessed 1, 3, 6 and 12 months after the intervention.

The study needs to include 700 subjects in order to reach 340 adolescents randomised, 170 in each group. It will concern 33 centres.

Discussion

This project could favour the targeting of addictive behaviours among vulnerable adolescents, and its application on a larger scale could be envisaged.

Trial registration

The Trial registration number is NCT04599270, and it was registered on the ClinicalTrials.gov public website.

The school-led Preventure study: Protocol of a cluster-randomised controlled trial of effectiveness to prevent adolescent alcohol misuse, internalising problems, and externalising problems through a personality-targeted intervention delivered by school staff

Mental disorders and problematic alcohol use are common, co-occurring and cause significant harm to individuals and society. It is critical to intervene early to prevent chronic and debilitating trajectories. Existing prevention programs among adolescents are limited in effectiveness and implementation. This Australian-first study will examine the effectiveness and feasibility of a personality-targeted program called Preventure, in preventing the onset or escalation of alcohol use, internalising problems and externalising problems among young Australians, when delivered by school staff. A cluster randomised controlled trial (RCT) of effectiveness will be conducted from 2020 to 2022 with 12 schools in Sydney, Australia, with students aged 13 years at baseline. Schools will be randomly allocated to the Preventure intervention or a control condition who will receive their usual Health Education curriculum. Schools allocated to the intervention will deliver Preventure to students scoring one standard deviation above the population mean on one of four personality traits. Preventure consists of two 90-minute group sessions that incorporate cognitive-behavioural therapy and motivational interviewing to promote coping skills. Students will be invited to complete surveys at baseline, 6- and 12-months following the intervention. Primary outcomes include student alcohol use, internalising problems, and externalising problems. Implementation fidelity, feasibility and acceptability will also be examined through surveys with school staff and students. Ethical approval has been obtained from the University of Sydney Human Research Ethics Committee, and the State Education Research Applications Process for research in public schools in NSW. This trial is registered with the Australian New Zealand Clinical Trials Registry (ACTRN12620000790943).

Early-life exposure to alcohol and the risk of alcohol-induced liver disease in adulthood

Alcohol consumption remains prevalent among pregnant and nursing mothers despite the well-documented adverse effects this may have on the offspring. Moderate-to-high levels of alcohol consumption in pregnancy result in fetal alcohol syndrome (FAS) disorders, with brain defects being chief among the abnormalities. Recent findings indicate that while light-to-moderate levels may not cause FAS, it may contribute to epigenetic changes that make the offspring prone to adverse health outcomes including metabolic disorders and an increased propensity in the adolescent-onset of drinking alcohol. On the one hand, prenatal alcohol exposure (PAE) causes epigenetic changes that affect lipid and glucose transcript regulating genes resulting in metabolic abnormalities. On the other hand, it can program offspring for increased alcohol intake, enhance its palatability, and increase acceptance of alcohol's flavor through associative learning, making alcohol a plausible second hit for the development of alcohol-induced liver disease. Adolescent drinking results in alcohol dependence and abuse in adulthood. Adolescent drinking results in alcohol dependence and abuse in adulthood. Alterations on the opioid system, particularly, the mu-opioid system, has been implicated in the mechanism that induces increased alcohol consumption and acceptance. This review proposes a mechanism that links PAE to the development of alcoholism and eventually to alcoholic liver disease (ALD), which results from prolonged alcohol consumption. While PAE may not lead to ALD development in childhood, there are chances that it may lead to ALD in adulthood.

Unhealthy life habits associated with self-induced vomiting and laxative misuse in Brazilian adolescents

Adolescence is a stage in life characterized by important social, cognitive, and physical changes. Adolescents are vulnerable to various psychosocial disorders, including eating disorders. We aimed to investigate the association between unhealthy habits, sociodemographic characteristics, and the practice of self-induced vomiting or laxative misuse in a representative sample of Brazilian adolescent girls and boys. Data from 102,072 students who participated in the National Adolescent School-based Health Survey were analyzed using the dependent variable: presence or absence of self-induced vomiting and/or laxative misuse; independent variables: consumption of unhealthy and high-calorie food items, age during first sexual intercourse, and the use of tobacco, alcohol, and/or illicit drugs. Associations between exposure and outcome were estimated using Poisson's regression models stratified by sex, and including region, school, age group, and mother's educational history as adjustment variables. Eating ultra-processed foods and age during first sexual intercourse were associated with self-induced vomiting and laxative misuse only for girls; all other variables (consuming unhealthy foods and using legal or illicit substances) were associated with these behaviors for both sexes after applying adjustment variables. Early interventions focusing on changing unhealthy behaviors may prevent development of eating disorders in adolescents. Our findings demonstrate a strong association of many unhealthy habits with laxative misuse and self-induced vomiting practices in Brazilian adolescents.

The Association between Gender Role Attitudes and Alcohol Use among Early Adolescents in Shanghai, China

Adolescent alcohol use was a major social and public health concern given its negative impacts. Previous studies indicated gender role attitudes (GRA) were associated with alcohol use; however, few studies focused on early adolescents (10 to 14 years) and similar researches were not found in China. Objective: This study sought to explore the association between GRA and alcohol use among early adolescents. Methods: A cross-sectional study was conducted among students in grades six to eight across three public secondary schools in Shanghai, China. Data were collected by Computer-Assisted Self-Interview (CASI) questionnaire on mobile tablets. Alcohol use was measured by self-report, and six items with 5-point Likert-type options assessed the attitude toward traditional gender roles. The logistic regression model was adopted to examine the associations between GAR and alcohol use. Results: Totally 1,631 adolescents aged 10 to 14 years with 50.33% of boys included in this study. The mean score of GRA in drinkers was significantly higher than nondrinkers among boys (3.03 vs. 2.78, p < 0.001) but not girls (2.15 vs. 2.18, p = 0.499). After controlling the covariates of age, depression, peers' substance use, social cohesion, etc., we found that more traditional GRA was associated with a higher risk of alcohol use among boys (OR = 1.39, 95%CI: 1.11-1.75), whereas the association was not significant among girls (OR = 0.96, 95%CI: 0.74-1.24). Conclusions: Traditional GRA may increase the risk of alcohol use among early adolescent boys, suggesting that altering traditional GRA among this population group may help to prevent alcohol use.

Association between gestational cannabis exposure and maternal, perinatal, placental, and childhood outcomes

Globally, the availability and formulations for the administration of cannabis are changing with decriminalization or legalization of recreational use in some jurisdictions, and the prescription of cannabis also occurring. These changes are likely to affect the prevalence of use, including by women of childbearing age. The effects of in utero and infant alcohol and tobacco exposure are well-documented, but the outcomes of cannabis exposure are less certain. The content of delta-9-tetrahydrocannabinol (THC), the psychoactive component of cannabis has progressively increased over several decades. This review explores the limited knowledge surrounding the epidemiology of gestational and postnatal cannabis exposure and implications for the mother-placenta-fetus/neonate triad. We examine cannabis' effects from antenatal and lactation exposure on (a) pregnancy and perinatal outcomes, (b) placental health, and (c) longer term cardiometabolic and neurodevelopmental risks and outcomes. Though definitive outcomes are lacking, gestational cannabis has been associated with increased risk of other substance use during pregnancy; impaired placental blood flow; increased risk of small for gestational age births; and associated complications. Childhood and adolescent outcomes are sparsely assessed, with suggested outcomes including increased risk of depression and attention-deficit hyperactivity disorder. Cardiometabolic implications of gestational cannabis use may include maternal fatty liver, obesity, insulin resistance, and increased risk of gestational diabetes mellitus (GDM), with potential consequences for the fetus. Clinical implications for pediatric practice were explored in a bid to understand any potential risk or impact on child health and development.

Psychological Distress Among Orphaned Youth and Youth Reporting Sexual Exploitation in Kampala, Uganda

Psychological distress is a priority health issue in low- and middle-income countries; however, it is inadequately addressed among vulnerable youth living in extremely underserved communities (i.e., on the streets and in the slums) who are at a high risk of experiencing adversity. The purpose of this study was to compute the prevalence of self-reported psychological distress among youth living in the slums of Kampala, Uganda, and examine how orphan status and commercial sexual exploitation (CSE) are related to youth psychological distress. Analyses are based on a 2014 cross-sectional survey of service-seeking youth (N = 1134) in Kampala, Uganda. Bivariate and multivariable multinomial regression analyses were used to determine associations between orphan status, sexual exploitation, and psychological distress (defined as experiencing the following proxy variables for more complex psychopathology: hopelessness and/or worry). Among all youth participants, 83.2% (n = 937) reported at least one type of psychological distress; 51.3% (n = 578) reported experiencing both types. The reported prevalence of any type of psychological distress was highest among youth who reported experiencing sexual exploitation (91.2%), double orphans (90.0%), and single orphans (83.8%); however, a high prevalence (76.7%) of any type of distress was also found among youth who reported both parents alive. Experiencing both types of distress was associated with being a double orphan (adjusted odds ratio [AOR] = 2.92, 95% confidence interval [CI] = [1.77, 4.81]), reporting CSE (AOR = 2.71, 95% CI = [1.67, 4.41]), and increased age (AOR = 1.31, 95% CI = [1.20, 1.44]). Psychological distress is prevalent among all youth living in the slums of Kampala and is independently associated with being a double orphan and experiencing CSE. These findings underscore the urgent need to intervene with all youth who reside in this particular underserved community, especially those who have lost both parents, and to prevent CSE among this vulnerable, underserved population.

A latent class analysis of heavy substance use in Young adulthood and impacts on physical, cognitive, and mental health outcomes in middle age

BACKGROUND

This study examines whether longitudinal patterns of persistent or experimental heavy substance use across young adulthood were associated with physical and mental health in midlife.

METHODS

Data (N = 21,347) from Monitoring the Future from adolescence (age 18) to midlife (age 40) were used. Repeated measures latent class analysis modeled patterns of patterns of cigarettes, alcohol, marijuana, and other illicit drugs across young adulthood (ages 18-30). Latent classes were then used as predictors of physical health problems, cognitive problems, self-rated health, and psychological problems in midlife (age 40), while controlling for sociodemographic variables (i.e., gender, race/ethnicity, parental education).

RESULTS

Identified classes were "Extreme Heavy Users" (3.9%), "Early Young Adult Users" (8.9%), "Cigarette Smokers" (9.2%), "All But Cigarette Smokers" (5.0%), "Frequent Alcohol Bingers" (10.4%), and "Not-Heavy Users" (62.6%). Extreme Heavy Users, Early Young Adult Users, and Cigarette Smokers had significantly poorer overall health based on a number of physical conditions and self-rated health. Extreme Heavy Users, Early Young Adult Users, Cigarette Smokers, and All But Cigarette Smokers had more cognitive problems than other classes. Extreme Heavy Users, Early Young Adult Users, Cigarette Smokers, and All But Cigarette Smokers were more likely to see a health professional for a psychological problem.

CONCLUSIONS

Patterns of heavy substance use were associated with health across decades. Regular cigarette smokers and heavy users across substances and ages had the worst health in midlife, although even those with time-limited use during young adulthood were at risk for later physical and cognitive health problems.

We Need to Delay the Age of Onset of Alcohol Consumption

In recent years, new consumption patterns, such as binge drinking, have increased among young people and have not always been recognized as problematic either by health personnel or by society in general, as they are intensive episodes, interspersed with no consumption periods. Although the prevalence of alcohol use disorders in the adult population continues to be higher in men than in women, these gender differences in relation to alcohol consumption are barely observed in adolescents between 14 and 18. Therefore, we are witnessing a change in the pattern of consumption, from regular to episodic, and an attenuation of gender differences. New patterns of alcohol consumption have not only been associated with an increased risk of alcohol use disorders in adult life, but also with neurocognitive involvement in youth. Understanding the risk and resilience factors of alcoholism or problematic drinking patterns will not only allow us to identify the most vulnerable group, but also to guide prevention programs towards protective factors; the skills that contribute to the natural abandonment of the pattern. Knowing the variables involved in the trajectories of abandonment and dependency would contribute to personalizing the interventions and increasing their efficacy and success—a lower relapse rate—, reducing the economic and socio-sanitary costs associated with alcohol dependency, as well as improving the health and well-being, family relations, work and social status of alcohol-dependent people.

The potential effects of autonomous vehicles on alcohol consumption and drink-driving behaviours

INTRODUCTION

By removing the need for a driver, autonomous vehicles (AV) are expected to substantially reduce rates of drink-driving. However, this benefit may be accompanied by an unintended negative consequence in the form of greater overall alcohol consumption due to increased availability of affordable and convenient transport.

AIMS

To assess: (i) the extent to which drinkers may choose to use AVs after consuming alcohol; (ii) the extent to which drinkers may consume more alcohol if they are using an AV afterwards; and (iii) whether demographic, alcohol-related and AV-related factors are associated with the likelihood of engaging in these behaviours.

DESIGN AND METHODS

A total of 1334 Australians of legal driving age who consume alcohol completed an online survey. Two regression models were used to calculate whether the analysed respondent characteristics were associated with intentions to use AVs after drinking and to consume more alcohol if using an AV afterwards.

RESULTS

Around half of the respondents (49%) reported being likely to use an AV after consuming alcohol, and over one-third (37%) reported being likely to consume more alcohol if using an AV afterwards. Younger age, more frequent alcohol consumption, a positive attitude to AVs and a preference for using 'ride-share' AVs were associated with a greater likelihood of engaging in these behaviours.

DISCUSSION AND CONCLUSIONS

The results suggest that the introduction of AVs is likely to reduce drink-driving rates while facilitating greater participation in heavy episodic drinking. This will constitute a challenge to policymakers in their efforts to minimise alcohol-related harms.

Sheltered adolescents’ background of exposure to violence and distressful experiences

ABSTRACT Objectives: to analyze the exposure to violence and distressful experiences lived by adolescents in institutional shelters in the city of Rio de Janeiro (previous to their admittance). Methods: a cross-sectional study carried out in public institutional shelter units, with a sample of 72 adolescents aged between 12 and 18 years. Data on sociodemographic aspects, family relationships and distressful experiences were obtained by means of the Parcours Amoureux des Jeunes instrument, validated for use in Brazil. Statistical analysis included estimates of prevalence and 95% confidence intervals. Results: high magnitudes of distressful experiences and overlapping abuses lived by adolescents were observed, especially violent events (72.2%), social exclusion (59.1%), and sexual harassment (48.6%). Conclusions: the study shows that adolescents under institutional sheltering come from a background of severe and frequent distressful experiences. These took place in multiple environments: family (prior to their institutional reception), community, and group.

Does binge drinking between the age of 18 and 25 years predict alcohol dependence in adulthood? A retrospective case-control study in France

OBJECTIVE

A retrospective case-control study was conducted to evaluate whether frequent binge drinking between the age of 18 and 25 years was a risk factor for alcohol dependence in adulthood.

SETTING

The Department of Addictive Medicine and the Clinical Investigation Center of a university hospital in France.

PARTICIPANTS

Cases were alcohol-dependent patients between 25 and 45 years and diagnosed by a psychiatrist. Consecutive patients referred to the Department of Addictive Medicine of a university hospital between 1 January 2017 and 31 December 2017 for alcohol dependence were included in the study. Controls were non-alcohol-dependent adults, defined according to an Alcohol Use Disorders Identification Test score of less than 8, and were matched on age and sex with cases. Data on sociodemographics, behaviour and alcohol consumption were retrospectively collected for three life periods: before the age of 18 years; between the age of 18 and 25 years; and between the age of 25 and 45 years. Frequency of binge drinking between 18 and 25 years was categorised as frequent if more than twice a month, occasional if once a month and never if no binge drinking.

RESULTS

166 adults between 25 and 45 years were included: 83 were alcohol-dependent and 83 were non-alcohol-dependent. The mean age was 34.6 years (SD: 5.1). Frequent binge drinking between 18 and 25 years occurred in 75.9% of cases and 41.0% of controls (p<0.0001). After multivariate analysis, frequent binge drinking between 18 and 25 years was a risk factor for alcohol dependence between 25 and 45 years: adjusted OR=2.83, 95% CI 1.10 to 7.25.

CONCLUSIONS

Frequent binge drinking between 18 and 25 years appears to be a risk factor for alcohol dependence in adulthood. Prevention measures for binge drinking during preadulthood, especially frequent binge drinking, should be implemented to prevent acute consequences as injury and death and long-term consequences as alcohol dependence.

Assessing the impacts of minimum legal drinking age laws on police-reported violent victimization in Canada from 2009 to 2013

BACKGROUND/AIM

Given that alcohol-related victimization is highly prevalent among young adults, the current study aimed to assess the potential impacts of Minimum Legal Drinking Age (MLDA) laws on police-reported violent victimization events among young people.

DESIGN

A regression-discontinuity (RD) approach was applied to victimization data from the Canadian Uniform Crime Reporting 2 (UCR2) Incident-based survey from 2009-2013. Participants/cases: All police-reported violent victimization events (females: n = 178,566; males: n = 156,803) among youth aged 14-22 years in Canada.

MEASUREMENTS

Violent victimization events, primarily consisting of homicide, physical assault, sexual assault, and robbery.

RESULTS

In comparison to youth slightly younger than the drinking age, both males and females slightly older than MLDA had significant and immediate increases in police-reported violent victimization events (females: 13.5%, 95% CI: 7.5%-19.5%, p < 0.001; males: 11.6%, 95% CI: 6.6%-16.7%, p < 0.001). Victimizations occurring in the evening rose sharply immediately after the MLDA by 22.8% (95% CI: 9.9%-35.7%, p =  0.001) for females and 19.3% (95% CI: 11.5%-27.2%, p < 0.001) for males. Increases in violent victimization immediately after MLDA were most prominent in bar/restaurant/open-air settings, with victimizations rising sharply by 44.9% (95% CI: 29.5%-60.2%, p < 0.001) among females and 18.3% (95% CI: 7.7%-29.0%, p =  0.001) among males.

CONCLUSIONS

Young people gaining minimum legal drinking age incur immediate increases in police-reported violent victimizations, especially those occurring in the evening and at bar/restaurant/open-air settings. Evidence suggests that increasing the MLDA may attenuate patterns of violent victimization in newly restricted age groups.

Substance use and Psychosocial Functioning of Adolescents in Benue State, Nigeria: Assessing the role of age

AIM

To assess whether Substance Use (SU) is associated with Psychosocial Function (PF) among adolescent.

METHODS

Using a self-administered validated instrument, we obtained information on demographic, SU (defined as self-reported affirmative use of one or more of any form of alcoholic drinks, cigarettes, hemps etc) and PF [using the adolescent psychosocial functioning inventory comprising of three subscales; optimism and coping strategies (OCS), behaviour and relationship problems (BRP) and general psychosocial dysfunction designed (GPD)] among 2272 apparently healthy adolescents. PF was categorized as 'elevated' if the psychosocial functioning index (PFI) score were >75th percentile, otherwise, 'not elevated' and multivariable-adjusted logistic regression was used to compute odds ratio (OR) and 95% confidence interval (CI) of SU for elevated PF risk. In addition, we applied Johnson Neyman (JN) technique to identifying the JN significance regions at which age moderated the SU-PF relationship at a statistical significance of two-sided P<0.05.

RESULTS

Prevalence of SU and elevated PF was 50.7% and 79.8% respectively. Prevalence of elevated PF differed insignificantly by sex, but the proportion of adolescent with elevated PFI on SU (82.6%) was significantly higher (P<0.001) compared to those with elevated PFI but not on SU (76.9%). Multivariable-adjusted odds of decreased OCS risk given SU exposure was; OR (95%CI): 1.3791 (1.1458-1.6698), P=0.0007. Similarly, multivariable-adjusted odds of elevated PF risk in the light of SU exposure was; OR (95%CI): 1.4286 (1.1617-1.7567), P=0.0007. Furthermore, the JN significance regions for moderated regression analyses of odds of decreased OCS risk was between 10.4years [OR (95%CI): 0.5820 (0.1411-1.0228), P=0.0097] and 16.7years [OR (95%CI): 0.3025 (0.0001-0.6050), P=0.0500].

CONCLUSION

Adolescents on SU are about one and half times at risk of psychosocial dysfunction and age significantly attenuated the SU-decreased OCS risk link particularly in early adolescence.

Impact of neuroimmune activation induced by alcohol or drug abuse on adolescent brain development

Evidence obtained in recent decades has demonstrated that the brain still matures in adolescence. Changes in neural connectivity occur in different regions, including cortical and subcortical structures, which undergo modifications in white and gray matter densities. These alterations concomitantly occur in some neurotransmitter systems and hormone secretion, which markedly influence the refinement of certain brain areas and neural circuits. The immaturity of the adolescent brain makes it more vulnerable to the effects of alcohol and drug abuse, whose use can trigger long-term behavioral dysfunction. This article reviews the action of alcohol and drug abuse (cannabis, cocaine, opioids, amphetamines, anabolic androgenic steroids) in the adolescent brain, and their impact on both cognition and behavioral dysfunction, including predisposition to drug abuse in later life. It also discusses recent evidence that indicates the role of the neuroimmune system response and neuroinflammation as mechanisms that participate in many actions of ethanol and drug abuse in adolescence, including the neurotoxicity and alterations in neurocircuitry that contribute to the dysfunctional behaviors associated with addiction. The new data suggest the therapeutic potential of anti-inflammatory targets to prevent the long-term consequences of drug abuse in adolescence.

Intensity of Daily Drinking and Its Relation to Alcohol Use Disorders

BACKGROUND

Daily drinking is an important public health concern and informative for evaluating diagnostic classification. In particular, daily binge drinkers might be considered as the prototype of some forms of alcoholism, as this drinking pattern may drive many alcohol use disorder (AUD) symptoms. However, daily drinking potentially captures a wide range of drinkers, including light-moderate daily drinkers who exhibit presumed control over their drinking behavior and might benefit from salutary effects on health. This study examined the heterogeneity of daily drinkers in detail.

METHODS

Data from the 2 waves of the National Epidemiologic Survey on Alcohol and Related Conditions were used. Participants who reported drinking "every day" during the last 12 months were classified as daily drinkers. A series of regression and logistic regression analyses were conducted to investigate the association between daily drinking and various outcomes.

RESULTS

Daily drinkers were found to vary considerably from each other with respect to diagnostic status, level of consumption, demographic composition, and a range of drinking and health correlates. Further, a substantial number of daily binge drinkers were not diagnosed with AUD under the DSM-IV or DSM-5, although in most groups, the DSM-5 criteria diagnosed a larger percentage of participants.

CONCLUSIONS

Daily drinkers represent a highly heterogeneous group, and the correlates of daily drinking depend on the usual quantity of daily drinks and the frequency of alcohol-related problems in a given sample. Moreover, AUD, defined both according to DSM-IV and DSM-5, did not capture more than 68% of daily binge drinkers. Given that daily binge drinking is an extremely high threshold for use, this finding may present a challenge for our current classification system.

Binge Drinking among adolescents is related to the development of Alcohol Use Disorders: results from a Cross-Sectional Study

Binge drinking (BD) is a common pattern of alcohol consumption among adolescents. At present few data are available on the possible relationship between BD and alcohol use disorders (AUD) in adolescents. The aim of this study was to assess the prevalence of BD and relationship between BD behavior and AUD among adolescents. A total of 2704 students attending 10 purposively selected high schools from three Italian provinces were surveyed. Questionnaires regarding socio-demographic data, pattern and amount of alcohol intake, smoking habits, use of illicit drugs, and physical activity were administered. AUD and affective disorders were also evaluated. Alcohol intake was reported by 2126 participants; 1278 reported at least one episode BD in the last year and 715 in the last month. A diagnosis of AUD was made in 165 adolescents. The prevalence of AUD was higher in adolescents that reported BD behavior than in those that did not report BD (11.6% vs 0.9%, respectively; p < 0.0001). Logistic regression showed a positive relationship between a diagnosis of AUD and BD behavior (OR 9.6; 95% CI 4.7–22·9; p < 0.0001). In conclusion alcohol consumption with the pattern of BD among adolescents is highly related to development of AUD.
