Health problems in adolescents with alcohol use disorders: self-report, liver injury, and physical examination findings and correlates

Continuing Care App for Probationers and Parolees with Substance use Disorders

This pilot proof-of-concept study examined the feasibility and acceptability of a Continuing Care mobile application (app) designed to meet the recovery and personal support needs of individuals under justice supervision who were receiving outpatient substance use disorder (SUD) treatment. The study included adults on probation or parole who were enrolled in an outpatient SUD treatment program (N = 15; 86.7% males). Participants were instructed to utilize the Continuing Care app daily for 4 weeks. At the end of the study, they completed a satisfaction questionnaire. Of the 15 participants enrolled in the study, 12 (80%) completed the Continuing Care app modules and the satisfaction questionnaire, and all of these participants indicated high levels of satisfaction with the app (on a scale of 1-10, Mean = 1.8, SD = 1.2). The Continuing Care app was well-utilized and perceived as valuable by this group of low-income, underserved, and hard-to-reach individuals. Further research is needed to refine app content and evaluate its ability to meaningfully enhance and extend the benefits of SUD treatment.

Parental Perceptions About Alcohol Use for Their Adolescent with Attention-Deficit/Hyperactivity Disorder

OBJECTIVE

Alcohol use can worsen attention-deficit/hyperactivity disorder (ADHD) symptoms, interfere with treatment, and worsen outcomes. Our objective was to describe parental perceptions of alcohol use for their adolescents with ADHD.

METHODS

Parents of adolescents with ADHD completed an online survey about perceptions of adolescent alcohol use for adolescents with ADHD. We described the level of parental concern about the impacts of alcohol use on their adolescent's functioning. We assessed whether specific covariates were associated with the level of parental concern.

RESULTS

Of 290 parents who completed the survey, 96.5% were women, and 66.1% had an educational attainment of college degree or higher. Most adolescents (75.4%) took ADHD medication, and 59.9% had comorbid anxiety or depression. Almost one-third (30.3%) of parents perceived that their adolescent was more likely to use alcohol because of ADHD, whereas 34.8% of parents disagreed with this and 34.8% of parents were neutral. Parents who suspected their adolescent regularly used alcohol were less likely to report concern about the impact of alcohol on their adolescent's school performance or ADHD medication effectiveness compared with parents who did not suspect regular adolescent alcohol use. Almost half of the parents (48.5%) did not report discussing the impact of alcohol use on ADHD with their adolescent.

CONCLUSION

Many parents of adolescents with ADHD do not understand the unique risks of alcohol use for their adolescents. In addition, if alcohol use harm is not obvious, parents may not perceive there to be concerns about alcohol use on functioning. Parental education about alcohol use and ADHD is needed.

A qualitative account of young people's experiences of alcohol screening and brief interventions in schools: SIPS Jr-HIGH trial findings

BACKGROUND

The United Kingdom (UK) has seen a decrease in the number of young people drinking alcohol. However, the UK prevalence of underage drinking still ranks amongst the highest in Western Europe. Whilst there is a wealth of evidence reporting on the effectiveness of both primary, and secondary interventions, there are few reports of the experiences of young people who receive them.

METHODS

The present study reports findings from interviews with 33 young people who were involved in an alcohol screening and brief intervention randomized controlled trial in schools in England. All interviews were analysed using inductive applied thematic analysis.

RESULTS

Three major themes were identified following the analysis process: 1) drinking identities and awareness of risk; 2) access to support and advice in relation to alcohol use; and 3) appraisal of the intervention and potential impact on alcohol use.

CONCLUSIONS

There appeared to be a reluctance from participants to describe themselves as someone who drinks alcohol. Furthermore, those who did drink alcohol often did so with parental permission. There was variation amongst participants as to how comfortable they felt talking about alcohol issues with school staff. Overall participants felt the intervention was useful, but would be better suited to 'heavier' drinkers.

Drinking beyond the binge threshold in a clinical sample of adolescents

BACKGROUND AND AIMS

Nearly all the research conducted on high-intensity drinking has focused on college and school-based samples, with recent calls for research to understand this risky drinking pattern in non-school-based samples and across time. This study aimed to characterize predictors and consequences of non-binge drinking, age- and gender-adjusted binge drinking (level I) and drinking at levels representing two or more times (level II) and three or more times the level I binge threshold (level III) in a clinical sample of adolescents followed into young adulthood.

DESIGN

Cross-sectional associations between non-binge drinking, binge levels, and negative alcohol-related consequences were examined during adolescence; prospective analyses tested whether adolescent non-binge drinking and binge levels predicted alcohol use disorder (AUD) symptoms in young adulthood and whether changes in drinking motives over time were associated with binge levels in young adulthood.

SETTING

US clinical settings.

PARTICIPANTS

A total of 432 adolescents (aged 12-18 years) with alcohol-related problems followed into young adulthood (aged 19-25 years).

MEASUREMENTS

Life-time drinking history, Structured Clinical Interview for DSM AUDs, and Inventory of Drinking Situations.

FINDINGS

Results were generally consistent with a distinction between binge level I versus levels II-III on various negative alcohol-related consequences in adolescence (Ps < 0.05) that were maintained in young adulthood (Ps < 0.01). The maintenance of relatively high endorsement of enhancement and social motives over time was associated with binge levels II-III in young adulthood (Ps < 0.001); decreases in coping motives were associated with less risky drinking in adulthood (P = 0.003).

CONCLUSIONS

Among US adolescents with alcohol-related problems who were followed-up in young adulthood (aged 19-25 years), standard threshold binge drinking (five or more drinks per occasion; level I) was generally associated with fewer alcohol-related consequences and problem behaviors than binge drinking at two or more times (level II) or three or more times (level III) the standard binge threshold.

Serum Exoglycosidases in Children and Adolescents With Harmful Alcohol Use

OBJECTIVE

There is a lack of accurate alcohol-use biomarkers in children/adolescents due to a short drinking duration/rapid normalization of elevated markers. We checked if lysosomal exoglycosidases, elevated earlier in binge-drinking young adults, can be applicable in children/adolescents as markers of harmful alcohol use.

METHODS

The serum activities (pKat/mL) of α-fucosidase (FUC), β-galactosidase (GAL), β-glucuronidase (GLU), β-hexosaminidase (HEX; its HEX A and HEX B isoenzymes), and α-mannosidase (MAN) were determined in 20 healthy controls (C) and 25 children/adolescents with harmful alcohol use (intoxicated by alcohol at hospital admission -AI1 and on the next day -AI2).

RESULTS

The serum HEX A and alanine aminotransferase (ALT) activity was significantly higher in the AI1 group than in the control. The activities of FUC, GAL, GLU, HEX B, and MAN were lower in the AI group. We found fair and poor accuracy, respectively, for increased enzymes HEX A and ALT. We found fair accuracy for decreased HEX B (AI1) and MAN (AI1), good accuracy for GLU (AI2), FUC (AI2), GAL (AI1, AI2), MAN (AI2), and excellent for FUC (AI1). Correlations were found: ALT with C-reactive protein (CRP), HEX A with white blood cell (WBC) count, blood alcohol concentration with FUC, MAN and HEX B, and WBC with FUC.

CONCLUSIONS

Decreased FUC, GLU, GAL, MAN values, and especially FUC (AI1) have the potential to be markers of harmful alcohol use in children/adolescents. The raised activity of HEX A and ALT points to the need for further research to check another inflammatory agent as potential alcohol marker in children and adolescents. Samples need to be collected before intravenous fluid therapy.

Alcohol Use by Youth

Alcohol use continues to be a major concern from preadolescence through young adulthood in the United States. Results of recent neuroscience research have helped to elucidate neurobiological models of addiction, substantiated the deleterious effects of alcohol on adolescent brain development, and added additional evidence to support the call to prevent and reduce underage drinking. This technical report reviews the relevant literature and supports the accompanying policy statement in this issue of Pediatrics.

Brief alcohol intervention for risky drinking in young people aged 14–15 years in secondary schools: the SIPS JR-HIGH RCT

Background

Adverse effects from young people’s alcohol consumption manifest in a range of physical and psychosocial factors, including neurological issues, cognitive impairment and risk-taking behaviours. The SIPS JR-HIGH pilot trial showed alcohol screening and brief intervention (ASBI) to be acceptable to young people and schools in the north-east of England.

Objectives

To conduct a two-arm, individually randomised controlled trial to evaluate the effectiveness and cost-effectiveness of ASBI for risky drinking in young people aged 14–15 years in the school setting, to monitor the fidelity of ASBI and to explore the barriers to, and facilitators of, implementation with staff, young people and parents.

Design

A baseline survey with a 12-month follow-up. Interviews with 30 school staff, 21 learning mentors and nine teachers, and 33 young people and two parents.

Setting

Thirty state schools in four areas of England: north-east, north-west, Kent and London.

Participants

Year 10 school pupils who consented to the study (aged 14–15 years, recruited between November 2015 and June 2016), school-based staff and parents of the young people who took part in the study.

Interventions

Young people who screened positively on a single alcohol screening question and consented were randomised to the intervention or control arm (blinded). The intervention was a 30-minute one-to-one structured brief intervention with a trained learning mentor and an alcohol leaflet. The control group received a healthy lifestyle leaflet (no alcohol information).

Main outcome measures

The primary outcome measure was total alcohol consumed in the last 28 days. Secondary outcomes related to risky drinking, general psychological health, sexual risk-taking, energy drink consumption, age of first smoking, quality of life, quality-adjusted life-years, service utilisation and demographic information.

Results

A total of 4523 young people completed the baseline survey, with 1064 screening positively (24%) and 443 being eligible to take part in the trial. Of those 443, 233 (53%) were randomised to the control arm and 210 were randomised to the intervention arm. Of the 443, 374 (84%) were successfully followed up at 12 months (intervention, n = 178; control, n = 196). The results were that the intervention showed no evidence of benefit for any alcohol-related measure when compared with the control arm. At 12 months we found a reduction from 61.9% to 43.3% using the Alcohol Use Disorders Identification Test cut-off point of 8 and cut-off point of 4 (69.0% to 60.7%). These results were not significant. A cost-effectiveness analysis showed that the average net cost saving of the brief intervention was £2865 (95% confidence interval –£11,272 to £2707) per year compared with usual practice, with the intervention showing a 76% probability of being cost saving compared with usual practice. The interview findings showed that school was an acceptable setting to carry out ASBI among staff and young people.

Limitations

Recruitment of parents to take part in interviews was poor. Only 18 ASBI sessions were recorded, making it difficult to assess internal validity.

Conclusions

Although the intervention was ineffective in reducing risky drinking in young people aged 14–15 years, it was well received by the young people and school staff who participated.

Future work

Uniform reporting of the outcomes used for ASBI would generate more robust conclusions on the effectiveness of ASBI in the future. Pilot feasibility studies should include more than one geographical area. Future work on involving parents is needed.

Determinants of Insomnia among Mothers during Postpartum Period in Northwest Ethiopia

Objective

Postpartum period is a state of instability that may be accompanied by mood liability, anxiety, insomnia, and neuropsychiatric disturbance in women. This neuropsychiatric disturbance has a negative influence on the child's psychological and physical development. Our aim was to see the level of sleep difficulties among postpartum mothers in three obstetric care settings in Ethiopia.

Method

Institutional based cross-sectional study was conducted at one referral hospital and two health centers. A total of 988 postpartum mothers had been interviewed for sleep difficulties by using Athens Insomnia Scale (AIS). Adjusted Odd Ratio (AOR) and 95% Confidence Interval (CI) were used and P-value <0.05 was used for indicating significant variables.

Result

The prevalence of sleep difficulty between four to six weeks of postpartum period was 21.8% (215/988). Marital status of divorced/widowed/separated [AOR= 2.29, 95% CI (1.40, 6.08)], no educational opportunity [AOR= 2.35, 95% CI (1.57, 3.51)], having poor social support [AOR=2.82, 95% CI (1.63, 4.88)], alcohol use [AOR=1.58, 95% CI (1.13, 2.22)], history of depression [AOR=1.93, 95% CI (1.13, 3.31)], and who has poor support from husband [AOR=1.94, 95% CI (1.18, 3.18)] had association with sleep difficulty.

Conclusion

There is a high magnitude of sleep difficulties during four to six weeks of postpartum period in postpartum mothers and they are associated with many preventable risk factors.

An exploration of adolescents' decisions to abstain or refrain from alcohol consumption in Australian social settings: a qualitative systematic review

BACKGROUND

A significant number of Australian adolescents consume alcohol, with almost two thirds of them doing so at risky levels. This is continuing to increase despite recent National Health and Medical Research Council (NHMRC) guidelines stipulating that no alcohol is the safest option. Measures initiated to reduce and prevent alcohol consumption by adolescents have limited effectiveness. Consumption of alcohol by Australian adolescents is a national concern because of the deleterious effects of alcohol consumption on adolescents' social, physical and neurological development, as well as other short- and long-term health risks, and the negative impact of alcohol-related violence and injury on the community. Understanding adolescents' decisions to abstain or refrain from alcohol consumption may provide valuable insights to assist in dealing with this significant social and health issue, more particularly about the mechanisms used by adolescents or their ability to make decisions about resisting or abstaining from alcohol consumption when exposed to alcohol in their social setting(s).

OBJECTIVES

The review aimed to synthesize the best available qualitative evidence on the decisions made or mechanisms used by adolescents who abstain or refrain from consuming alcohol in any social setting where alcohol is available.

INCLUSION CRITERIA

Adolescents aged between 14 and 19 years who reside in Australia.The phenomenon of interest was abstinence from or resistance to alcohol consumption when exposed to alcohol in social situations.This review considered studies that focused on qualitative data, including, but not limited to,designs such as phenomenology, grounded theory, action research and exploratory studies.

SEARCH STRATEGY

A three-step search strategy was used. An initial search to identify keywords only was undertaken in Medline and CINAHL. This was followed by an expanded search using all identified keywords and index terms specific to each included database. The reference lists of included papers were then searched for any other relevant studies.

METHODOLOGICAL QUALITY

No studies met the inclusion criteria sufficiently to progress to critical appraisal.

DATA EXTRACTION

No studies progressed to data extraction.

DATA SYNTHESIS

Data synthesis was not undertaken as no study met the inclusion criteria.

RESULTS

Although a number of studies retrieved indicated they had qualitative elements to their studies, the qualitative data was not reported.

CONCLUSIONS

Although a number of studies met some aspects of the inclusion criteria there was insufficient reporting of the phenomenon of interest. Due to the lack of studies meeting the inclusion criteria, no conclusions can be drawn for clinical practice. A lack of qualitative data on this topic has been identified. Thus there is a great need for qualitative research to understand and know more about what enables an adolescent to abstain or refrain from consumption in order to inform or formulate effective interventions, policies or plans to prevent or reduce the volume of alcohol consumed by Australian adolescents.

The concurrent validity of the Problem Oriented Screening Instrument for Teenagers (POSIT) substance use/abuse subscale in adolescent patients in an urban federally qualified health center

BACKGROUND

The Problem Oriented Screening Instrument for Teenagers (POSIT) substance use/abuse subscale has been validated with high school students, adolescents with criminal justice involvement, and adolescent substance use treatment samples using the Diagnostic and Statistical Manual of Mental Disorders (DSM)-III-R and DSM-IV. This study examines the concurrent validity of the POSIT's standard 17-item substance use/abuse subscale and a revised, shorter 11-item version using DSM-5 substance use disorder diagnoses.

METHODS

Adolescents (N = 525; 93% African American, 55% female) 12-17 years of age awaiting primary care appointments at a Federally Qualified Health Center in Baltimore, Maryland completed the 17-item POSIT substance use/abuse subscale and items from a modified World Mental Health Composite International Diagnostic Interview corresponding to DSM-5 alcohol use disorder (AUD) and cannabis use disorder (CUD). Receiver operating characteristic curves, sensitivities, and specificities were examined with DSM-5 AUD, CUD, and a diagnosis of either or both disorders for the standard and revised subscales using risk cutoffs of either 1 or 2 POSIT "yes" responses.

RESULTS

For the 17-item subscale, sensitivities were generally high using either cutoff (range: 0.79-1.00), although a cutoff of 1 was superior (sensitivities were 1.00 for AUD, CUD, and for either disorder). Specificities were also high using either cutoff (range: 0.81-0.95) but were higher using a cutoff of 2. For the 11-item subscale, a cutoff of 1 yielded higher sensitivities than a cutoff of 2 (ranges for 1 and 2: 0.96-1.00 and 0.79-0.86, respectively). Specificities for this subscale were higher using a cutoff of 2 (ranges for 1 and 2: 0.82-0.89 and 0.89-0.96, respectively).

CONCLUSIONS

Findings suggest that the POSIT's substance use/abuse subscale is a potentially useful tool for screening adolescents in primary care for AUD or CUD using a cutoff of 1 or 2. The briefer, revised subscale may be preferable to the standard subscale in busy pediatric practices.

A simulation study of the effects of alcohol on driving performance in a Chinese population

Driving under the influence of alcohol (DUIA) is a significant factor contributing to road traffic crashes, injuries, and fatalities. Although the effects of alcohol on driving performance are widely acknowledged, studies of the effects of alcohol impairment on driving performance and particularly on the control system of Chinese adults are rare. This study attempts to evaluate the effects of alcohol on the driving performance of Chinese adults using a driving simulator.

METHOD

A double-blind experimental study was conducted to evaluate the effects of alcohol impairment on the driving performance of 52 Chinese participants using a driving simulator. A series of simulated driving tests covering two driving modules, including emergency braking (EB) and following braking (FB), at 50km/h and 80km/h were performed. Linear mixed models were established to evaluate driving performance in terms of braking reaction time (BRT), the standard deviation of lateral position (SD-LANE), and the standard deviation of speed (SD-SPEED).

RESULTS

Driving performance in terms of BRT and SD-LANE was highly correlated with the level of alcohol consumption, with a one-unit increase in breath alcohol concentration (BrAC) degrading BRT and SD-LANE by 0.3% and 0.2%, respectively. Frequent drinkers generally reacted faster in their BRT than less-frequent drinkers and non-drinkers by 10.2% and 30.6%, respectively. Moreover, alcohol impairment had varying effects on certain aspects of the human control system, and automatic action was less likely to be affected than voluntary action from a psychological viewpoint.

CONCLUSION

The findings should be useful for planning and developing effective measures to combat drink driving in Chinese communities.

A Social Domain Approach to Informant Discrepancies in Parental Solicitation and Family Rules

An extensive body of research has explored the effects of parental monitoring on adolescent outcomes, but studies consistently find substantial discrepancies between parent and adolescent reports of different monitoring behaviors. Little research has examined whether parents and adolescents are more or less discrepant when reporting on parents' rules or solicitation for different adolescent problem and health risk behaviors and few studies have explored potential explanatory variables to explicate individual variability in parent-adolescent discrepant reporting. To address this gap in the literature, the current study examined discrepancies in mother-adolescent reports of family rules and solicitation across five distinct adolescent behaviors: personal behaviors and four different risk behaviors (alcohol-related, cyber, over- and under-eating). Participants were 143 mother-adolescent dyads (Adolescent M age  = 14.42, SD = 1.73, range = 12-18, 81 % white, 60 % female). Mean-level discrepancies between maternal and adolescent reports significantly differed by category of adolescent behavior and also varied as a function of reported parental monitoring behavior (rules vs. solicitation). Discrepancies in mother-adolescent reports of behavior-specific rules and solicitation were positively associated with discrepancies in mother and adolescent judgments of the harmfulness of the activities. The results demonstrate that discrepancies in mother-adolescent reports of family process differ by category of adolescent behavior and may be undergirded by differences in mother and adolescent informational assumptions about the potential harm involved with different activities.

Solitary cannabis use in adolescence as a correlate and predictor of cannabis problems

BACKGROUND

Most adolescent cannabis use occurs in social settings among peers. Solitary cannabis use during adolescence may represent an informative divergence from normative behavior with important implications for understanding risk for cannabis problems. This longitudinal study examined associations of adolescent solitary cannabis use with levels of cannabis use and problems in adolescence and in young adulthood.

METHODS

Cannabis using-adolescents aged 12-18 were recruited from clinical programs (n=354; 43.8% female; 83.3% Caucasian) and community sources (n=93; 52.7% female; 80.6% Caucasian). Participants reported on cannabis use patterns and diagnostic symptoms at baseline and multiple follow-ups into young adulthood.

RESULTS

Compared to social-only users, adolescent solitary cannabis users were more likely to be male and reported more frequent cannabis use and more DSM-IV cannabis use disorder (CUD) symptoms. Regression analyses showed that solitary cannabis use in adolescence predicted CUD symptom counts in young adulthood (age 25) after controlling for demographic variables and the frequency of adolescent cannabis use. However, solitary adolescent cannabis use was no longer predictive of age 25 CUD symptoms after additionally controlling for adolescent CUD symptoms.

CONCLUSIONS

Solitary cannabis use is associated with greater cannabis use and problems during adolescence, but evidence is mixed that it predicts young adult cannabis problems.

Sleep and circadian contributions to adolescent alcohol use disorder

Adolescence is a time of marked changes across sleep, circadian rhythms, brain function, and alcohol use. Starting at puberty, adolescents' endogenous circadian rhythms and preferred sleep times shift later, often leading to a mismatch with the schedules imposed by secondary education. This mismatch induces circadian misalignment and sleep loss, which have been associated with affect dysregulation, increased drug and alcohol use, and other risk-taking behaviors in adolescents and adults. In parallel to developmental changes in sleep, adolescent brains are undergoing structural and functional changes in the circuits subserving the pursuit and processing of rewards. These developmental changes in reward processing likely contribute to the initiation of alcohol use during adolescence. Abundant evidence indicates that sleep and circadian rhythms modulate reward function, suggesting that adolescent sleep and circadian disturbance may contribute to altered reward function, and in turn, alcohol involvement. In this review, we summarize the relevant evidence and propose that these parallel developmental changes in sleep, circadian rhythms, and neural processing of reward interact to increase risk for alcohol use disorder (AUD).

Course of alcohol symptoms and social anxiety disorder from adolescence to young adulthood

BACKGROUND

There is limited knowledge of the course of social anxiety disorder (SAD) from adolescence into adulthood, and how SAD and alcohol use disorder (AUD) symptoms change together over time. The current study examined how persistent and adolescent-limited SAD relate to alcohol symptom trajectories across adolescence and into adulthood, as well as gender differences in the course of SAD and AUD symptoms.

METHODS

Participants were 788 youth (ages 12 to 18 at the baseline assessment; 46.2% female; 80.5% White) recruited from the community (n = 220) and from clinical programs (n = 568). Youth completed clinical interviews on their lifetime history of AUD symptoms and SAD at baseline and were followed through age 25. Multivariate polynomial growth mixture modeling was used to estimate developmental trajectories for SAD and AUD symptoms separately, then together in a dual trajectory model. Gender differences were examined using a classify-analyze approach.

RESULTS

Three SAD trajectory classes were identified: adolescent-limited (15%), persistent (6%), and no SAD (79%). For AUD symptoms, 5 trajectories were identified: severe (10%), moderate (22%), remitting (18%), young adult onset (22%), and stable low (28%). Those with a history of SAD were about twice as likely to be in the severe AUD symptom class compared to those without a history of SAD. Compared to those with persisting SAD, those in the adolescent-limited SAD class were more likely to belong to the stable low AUD trajectory. Compared to males with SAD, females with SAD were less likely to be in the moderate AUD symptom class and were more likely to be in stable low and young adult onset AUD symptom classes.

CONCLUSIONS

A history of SAD was associated with membership in the severe AUD trajectory group. The association of gender with SAD and AUD differed depending on developmental period. Future research should examine whether treating SAD in early adolescence may prevent subsequent AUD symptoms.

Sleep and use of alcohol and drug in adolescence. A large population-based study of Norwegian adolescents aged 16 to 19 years

BACKGROUND

Changes in sleep patterns and increased substance involvement are common in adolescence, but our knowledge of the nature of their association remains limited. The aim of this study was to examine the association between several sleep problems and sleep behaviours, and use and misuse of alcohol and illicit drugs using data from a large population-based sample.

METHODS

A large population-based study from Norway conducted in 2012, the youth@hordaland study, surveyed 9328 adolescents aged 16-19 years (54% girls). Self-reported sleep measures provided information on sleep duration, sleep deficit, weekday bedtime and bedtime difference and insomnia. The main dependent variables were frequency and amount of alcohol consumption and illicit drug use, in addition to the presence of alcohol and drug problems as measured by CRAFFT.

RESULTS

The results showed that all sleep parameters were associated with substance involvement in a dose-response manner. Short sleep duration, sleep deficit, large bedtime differences and insomnia were all significantly associated with higher odds of all alcohol and drug use/misuse measures. The associations were only partly attenuated by sociodemographics factors and co-existing symptoms of depression and ADHD.

CONCLUSIONS

To the best of our knowledge, this is the first population-based study to examine the association between sleep, and alcohol and drug use, by employing detailed measures of sleep behaviour and problems, as well as validated measures on consumption of alcohol and illicit drug use. The findings call for increased awareness of the link between sleep problems and alcohol and drugs use/misuse as a major public health issue.

Suicidal ideation in depressed postpartum women: Associations with childhood trauma, sleep disturbance and anxiety

BACKGROUND

Suicide is one of the leading causes of death in postpartum women. Identifying modifiable factors related to suicide risk in mothers after delivery is a public health priority. Our study aim was to examine associations between suicidal ideation (SI) and plausible risk factors (experience of abuse in childhood or as an adult, sleep disturbance, and anxiety symptoms) in depressed postpartum women.

METHODS

This secondary analysis included 628 depressed mothers at 4-6 weeks postpartum. Diagnosis was confirmed with the Structured Clinical Interview for DSM-IV. We examined SI from responses to the Edinburgh Postnatal Depression Scale-EPDS item 10; depression levels on the Structured Interview Guide for the Hamilton Depression Rating Scale, Atypical Depression Symptoms (SIGH-ADS); plus sleep disturbance and anxiety levels with subscales from the EPDS and SIGH-ADS items on sleep and anxiety symptoms.

RESULTS

Of the depressed mothers, 496 (79%) 'never' had thoughts of self-harm; 98 (15.6%) 'hardly ever'; and 34 (5.4%) 'sometimes' or 'quite often'. Logistic regression models indicated that having frequent thoughts of self-harm was related to childhood physical abuse (odds ratio-OR = 1.68, 95% CI = 1.00, 2.81); in mothers without childhood physical abuse, having frequent self-harm thoughts was related to sleep disturbance (OR = 1.15, 95% CI = 1.02, 1.29) and anxiety symptoms (OR = 1.11, 95% CI = 1.01, 1.23).

DISCUSSION

Because women with postpartum depression can present with frequent thoughts of self-harm and a high level of clinical complexity, conducting a detailed safety assessment, that includes evaluation of childhood abuse history and current symptoms of sleep disturbance and anxiety, is a key component in the management of depressed mothers.

Statewide Administration of the CRAFFT Screening Tool: Highlighting the Spectrum of Substance Use

BACKGROUND

Adolescent alcohol and drug use in the United States are associated with negative consequences spanning multiple domains. Much of the public health surveillance of these behaviors relies on self-report survey data. These data frequently takes the form of frequency or prevalence data for specific substances, which may not provide a complete picture of use.

OBJECTIVES

This study analyzes a state-level survey that includes the CRAFFT screening tool. The study's goal is to elucidate the spectrum of substance use severity across a large segment of substance-using adolescents attending schools in the state of Indiana and to assess the contribution of a variety of predictor variables to the variance between users falling into each category of use severity.

METHODS

Data were collected in 2011 from 168,801 adolescents, of whom 25,204 met the inclusion criteria for this study. The authors utilize multinomial logit analyses to highlight variables, including sociodemographic data, poly-drug use, and risk/protective behavior scales, associated with each category of use.

RESULTS

Seriousness of use is not uniform across substance-using adolescents; 49% were categorized as nonproblem users, 33% as problem users, and 18% as dependent users. Risk and protective factors predict adolescents' severity of substance use, but do not do so uniformly. Poly-drug use is a significant predictor of problem use and dependent use as well.

CONCLUSIONS

The CRAFFT may provide a more nuanced perspective of adolescent substance use than frequency/prevalence data alone; the authors describe the implications derived from these data and analyses to the adolescent prevention and treatment systems.

Circadian rhythms and risk for substance use disorders in adolescence

PURPOSE OF REVIEW

This article explores recent research in adolescent circadian rhythms, neurobiological changes influencing affective regulation and reward responding, and the emergence of substance use and related problems.

RECENT FINDINGS

Recent findings have confirmed that adolescents with drug and alcohol problems are also beset by sleep problems, and have advanced our understanding of the relationship between sleep problems and substance involvement in this developmental period. During adolescence, a shift to later preferred sleep times interacts with early school start times to cause sleep loss and circadian misalignment. Sleep loss and circadian misalignment may disrupt reward-related brain function and impair inhibitory control. Deficits or delays in mature reward and inhibitory functions may contribute to adolescent alcohol use and other substance involvement.

SUMMARY

An integration of the available research literature suggests that changes in sleep and circadian rhythms during adolescence may contribute to accelerated substance use and related problems.

A longitudinal study of insomnia and other sleep complaints in adolescents with and without alcohol use disorders

BACKGROUND

Sleep disturbances are both common and well-characterized in adults with alcohol use disorders (AUDs), but have received little study in adolescents with AUDs. Furthermore, a handful of studies suggest that sleep complaints are a risk factor for AUDs. However, no published studies have yet examined the longitudinal course of sleep complaints in adolescents with AUDs; in particular, it remains unclear how persistent AUD-associated sleep complaints are in this age group, and what types of sleep complaints are most relevant to alcohol-use symptoms. We investigated these questions in a 5-year longitudinal study of adolescents with and without AUDs at baseline.

METHODS

Participants were 696 adolescents (age 12 to 19) from a longitudinal study at the Pittsburgh Adolescent Alcohol Research Center. At baseline, 347 participants had a current AUD (AUD+), while 349 had no current or past AUD (AUD-). We examined sleep and alcohol involvement at baseline as well as 1-, 3-, and 5-year follow-up visits. Sleep variables included self-reported insomnia and hypersomnia, as well as variability in weekday-weekend sleep duration, all at baseline. Covariates included sex, age, current alcohol symptoms, and depression severity.

RESULTS

The AUD+ group reported more overall sleep disturbance at baseline, including greater insomnia and hypersomnia complaints, and greater variability in weekday-weekend sleep duration. Group differences in insomnia and hypersomnia complaints persisted to the 5- and 3-year follow-ups, respectively. In the AUD- group, greater insomnia complaints at baseline predicted an increase in alcohol symptoms at the 1-year follow-up, while greater variability in sleep duration at baseline predicted an increase in alcohol symptoms at the 3- and 5-year follow-ups.

CONCLUSIONS

These results complement previous findings in other samples, indicating that insomnia and other sleep problems are a chronic predicament for adolescents with AUDs. The findings also suggest that sleep disturbances may place adolescents without AUDs at an elevated risk of developing alcohol problems.

Solitary Alcohol Use in Teens Is Associated With Drinking in Response to Negative Affect and Predicts Alcohol Problems in Young Adulthood

Adolescent solitary drinking may represent an informative divergence from normative behavior, with important implications for understanding risk for alcohol-use disorders later in life. Within a self-medication framework, we hypothesized that solitary alcohol use would be associated with drinking in response to negative affect and that such a pattern of drinking would predict alcohol problems in young adulthood. We tested these predictions in a longitudinal study in which we examined whether solitary drinking in adolescence (ages 12-18) predicted alcohol-use disorders in young adulthood (age 25) in 466 alcohol-using teens recruited from clinical programs and 243 alcohol-using teens recruited from the community. Findings showed that solitary drinking was associated with drinking in response to negative affect during adolescence and predicted alcohol problems in young adulthood. Results indicate that drinking alone is an important type of alcohol-use behavior that increases risk for the escalation of alcohol use and the development of alcohol problems.

Persistent hypertransaminasemia in asymptomatic children: A stepwise approach

We aimed to examine the major causes of isolated chronic hypertransaminasemia in asymptomatic children and develop a comprehensive diagnostic flow diagram. A MEDLINE search inclusive of publications throughout August 2012 was performed. We found only a small number of publications that had comprehensively investigated this topic. Consequently, it was difficult to construct a diagnostic flowchart similar to those already available for adults. In children, a “retesting panel” prescription, including gamma-glutamyl transpeptidase and creatine kinase in addition to aminotransferases, is considered a reasonable approach for proficiently confirming the persistence of the abnormality, ruling out cholestatic hepatopathies and myopathies, and guiding the subsequent diagnostic steps. If re-evaluation of physical and historical findings suggests specific etiologies, then these should be evaluated in the initial enzyme retesting panel. A simple multi-step diagnostic algorithm incorporating a large number of possible pediatric scenarios, in addition to the few common to adults, is available. Accurately classifying a child with asymptomatic persistent hypertransaminasemia may be a difficult task, but the results are critical for preventing the progression of an underlying, possibly occult, condition later in childhood or during transition. Given the high benefit/cost ratio of preventing hepatic deterioration, no effort should be spared in diagnosing and properly treating each case of persistent hypertransaminasemia in pediatric patients.

Integrating substance use treatment into adolescent health care

Substance use (SU) problems are common among adolescents, a serious health risk for them and a major public health problem, but are inadequately addressed in most pediatric health care settings. Primary care offers an excellent context for SU assessment and treatment for adolescents and their families, offering better access and a less stigmatized environment for receiving treatment than specialty programs. This paper examines the literature on the integration of substance use treatment with adolescent health care, focusing on 2 areas: Screening, Brief Intervention, and Referral to Treatment (SBIRT) in Emergency Departments and Primary Care, and School- and College-Based Health Centers.

Age- and ethanol concentration-dependent effects of acute binge drinking in the HIV-1 transgenic rat

BACKGROUND

Binge drinking is common in young people. Alcoholic beverages vary significantly in their ethanol (EtOH) concentration (alcohol by volume). We previously showed EtOH concentration-dependent activation of the hypothalamic supraoptic nucleus. In the HIV-infected population, incidence of alcohol abuse is close to 50%. We found age-dependent expression of HIV-1 viral proteins in the HIV-1 transgenic (HIV-1Tg) rat. Thus, we hypothesized that there are age- and EtOH concentration-dependent effects of binge drinking in HIV-1-positive individuals.

METHODS

Blood ethanol concentration was measured in adult F344 rats after gavage (i.g.) administration of water, 20% EtOH, or 52% EtOH. We also compared expression of the HIV-1 viral protein Tat in the brain, spleen, and liver of adult and adolescent HIV-1Tg rats following binge i.g. administration of water, 20% EtOH, or 52% EtOH for 3 days (4.8 g/kg/d) using absolute quantitative real-time reverse transcription-polymerase chain reaction. In a parallel study, we assessed age-dependent motor function in the HIV-1Tg rats 1 day after exposure to 20% EtOH using the open-field test.

RESULTS

Blood ethanol concentration was significantly higher in the 52% EtOH-treated F344 rats compared to the 20% EtOH animals at 90 minutes posttreatment. In the adult HIV-1Tg rats, HIV-1 Tat expression (copies per microgram of total RNA) was significantly increased in the brain, liver, and spleen of the 52% EtOH group, but not in the 20% EtOH group. However, in the adolescent animals, HIV-1 Tat expression in the 52% EtOH group was increased in the brain and liver, but not in the spleen. A significant reduction in locomotor activity occurred in 20% EtOH-treated adult HIV-1Tg rats compared to the water control, although no difference was observed in the adolescent HIV-1Tg animals.

CONCLUSIONS

Our data indicate that binge alcohol drinking can have age- and EtOH concentration-dependent effects in the presence of HIV-1 infection.

Pharmacotherapy for adolescent alcohol use disorder

Alcohol use disorder (AUD) occurs in few young adolescents, but is as common as in adults by the late teens. To address problems with the current American Psychiatric Association DSM-IV criteria, the anticipated DSM-V will eliminate the distinction between substance abuse and dependence in favour of a single category. For adolescents, pharmacotherapy for AUD may target alcohol withdrawal symptoms, alcohol consumption reinforcement properties, craving or co-morbid mental disorders. While uncommon among adolescents, severe alcohol withdrawal may require the closely monitored application of benzodiazepines. Disulfiram alters alcohol metabolism and has been shown to increase abstinence in adolescents with AUD, but sufficient motivation to maintain abstinence is needed for this approach to be appropriate. Medications to reduce alcohol craving, including naltrexone and acamprosate, may also assist some adolescents in maintaining abstinence. Adolescents with AUD typically also have co-morbid mental disorders and problems with other substances. Co-morbid mental disorders, such as major depressive disorder and attention-deficit hyperactivity disorder, may be addressed by pharmacotherapy. The potential for interactions between prescribed medications and alcohol or illicit substances necessitates patient education and monitoring. While there is a paucity of empirical information on the applicability of these pharmacotherapy approaches in adolescents, cautious application of these medications in selected cases in the context of systematic psychosocial interventions is warranted to promote abstinence and address associated problems.

Substance abuse prevalence and its relation to scholastic achievement and sport factors: an analysis among adolescents of the Herzegovina-Neretva Canton in Bosnia and Herzegovina

BACKGROUND

Substance abuse among adolescents is a major public health and social problem. However, studies rarely investigate the relationships between substance abuse, educational achievement and sport factors. Substance abuse is an even more significant problem in societies that have experienced trauma, such as Bosnia and Herzegovina, which have had recent wars. The aims of this study were to investigate substance abuse among adolescents in Bosnia and Herzegovina and to study the potential gender-specific relationships between a) sport factors (physical activity/exercise/athletic participation) and substance abuse and b) scholastic achievement and substance abuse.

METHODS

Our sample consisted of 1,032 adolescents who were 17 to 18 years old (435 boys and 597 girls) and who were in the final grade of high school. These subjects were randomly selected from the territory of Herzegovina-Neretva Canton of Bosnia and Herzegovina. Retrospective testing was performed using an extensive self-administered questionnaire. The questionnaire included questions involving topics such as sociodemographic variables, scholastic variables, sport factors, and substance abuse data (smoking habits, drugs consumption and alcohol consumption using the AUDIT questionnaire). Descriptive statistics, frequencies, analyses of the differences and correlational analyses were performed.

RESULTS

Our results found that greater than one-third of the boys and one-fourth of the girls were daily smokers, and almost half of the boys and one-fifth of the girls practiced harmful drinking; other drugs (i.e. heroin, cocaine, amphetamines, etc.) were rarely consumed. Boys dominated in sport factors, whereas girls were more successful in scholastic achievement. Approximately 23% of the boys and 6% of the girls reported that they practiced harmful drinking and smoked simultaneously. Educational failure, which was defined as having one or more negative grades at the end of the last two school years, was identified in 20% of the boys and 9% of the girls. In both genders, substance abuse was negatively correlated with educational achievement, and half of those students who failed educationally reported daily smoking. Among the girls who experienced education failure, 33% were smokers, and 22% practiced harmful drinking. Sport factors were weakly correlated with substance abuse in boys; thus, we could not support the hypothesis that sports are a protective factor against substance abuse among male adolescents. In girls, participation in team sports was related with a higher incidence of smoking, but there was no evidence of sport factors having an influence on the consumption of alcohol.

CONCLUSION

In this study, the incidence of smoking and the consumption of alcohol were alarmingly high. These findings demonstrate the need for intervention programs to address these issues. These problems are particularly important, considering that substance abuse has a negative impact on educational achievement among boys and girls, and sport factors have not been found to be protective factors against substance abuse.

Prevalence and correlates of insomnia in a polish sample of alcohol-dependent patients

BACKGROUND

Insomnia is an important symptom in alcohol-dependent patients because it may persist despite abstinence and predispose to relapse to drinking. The goal of the present study was to evaluate the prevalence and clinical correlates of insomnia in a sample of 302 alcohol-dependent patients admitted to treatment programs in Poland.

METHODS

Participants were mostly men (73.8%) with a mean (SD) age of 43.5 (9.7) years. Insomnia in the past 1 month was assessed using a total score of 6 or higher on the Athens Insomnia Scale.

RESULTS

Insomnia affected 62.9% of patients, and delayed sleep induction was the most common subtype. Insomnia was associated in bivariate analyses with less education, inadequate finances, problem drinking at an earlier age of onset, drinking frequency and quantity, drinking-related consequences, severity of alcohol and nicotine dependence, psychiatric and physical severity, and a childhood history of sexual or physical abuse (p < 0.05). Logistic regression analysis showed that mental and physical health status, severity of alcohol dependence, number of drinking days in the past 3 months, and childhood abuse were independent predictors of insomnia, explaining approximately 30 to 40% of the variance.

CONCLUSIONS

More than 60% of alcohol-dependent patients in a Polish sample screened positive for insomnia using a validated scale, a rate similar to those assessed with other scales in other countries. The study also showed that insomnia in alcohol-dependent patients is associated with poor physical health and childhood abuse, similar to the general population. The multifactorial nature of insomnia in alcohol-dependent patients has treatment implications.

Age differences in the expression of acute and chronic tolerance to ethanol in male and female rats

BACKGROUND

Ontogenetic differences in response to ethanol (EtOH) challenge have been observed under a variety of circumstances, including varying reports of developmental differences in the expression of tolerance to EtOH. The purpose of the present experiment was to further explore potential differences in acute (AT) and chronic (CT) tolerance expression between adolescent and adult, male and female Sprague-Dawley rats, using the social interaction test.

METHODS

AT and CT to the social suppressing effects of a moderate dose of EtOH was assessed in adolescent and adult rats following intraperitoneal injections of 2.0 g/kg EtOH or saline daily for 10 days. At test, adults and adolescents were challenged with 1.0 or 1.25 g/kg EtOH, respectively, with AT and CT assessed at 5 and 25 minutes postinjection using ratios of impairment to brain ethanol concentrations (BrECs) at each time period (CT) and within-session declines in impairment relative to BrECs (AT).

RESULTS

In adolescents, 10 days of EtOH pre-exposure resulted in evidence of CT at 25 minutes postinjection, perhaps associated with an enhanced expression of AT. Among adults, signs of CT were seen at 5 minutes postinjection in adults, and may reflect neuroadaptations unassociated with AT, as with evidence of tolerance emerging only in adult control animals repeatedly exposed to saline injection prior to EtOH challenge on test day. Sex differences in tolerance expression were not observed at either age.

CONCLUSIONS

Our results show ontogenetic differences between adolescents and adults in the short- and long-term neuroadaptations that they express in response to repeated perturbations with EtOH. Together these findings add age of exposure and time of testing within the intoxication period as critical variables to be considered when exploring the complex relationship between AT and CT.

Alcohol use by youth and adolescents: a pediatric concern

Alcohol use continues to be a major problem from preadolescence through young adulthood in the United States. Results of recent neuroscience research have substantiated the deleterious effects of alcohol on adolescent brain development and added even more evidence to support the call to prevent and reduce underaged drinking. Pediatricians should be knowledgeable about substance abuse to be able to recognize risk factors for alcohol and other substance abuse among youth, screen for use, provide appropriate brief interventions, and refer to treatment. The integration of alcohol use prevention programs in the community and our educational system from elementary school through college should be promoted by pediatricians and the health care community. Promotion of media responsibility to connect alcohol consumption with realistic consequences should be supported by pediatricians. Additional research into the prevention, screening and identification, brief intervention, and management and treatment of alcohol and other substance use by adolescents continues to be needed to improve evidence-based practices.

Screening and brief intervention for underage drinkers

In a 2007 report, the US Surgeon General called for health care professionals to renew efforts to reduce underage drinking. Focusing on the adolescent patient, this review provides health care professionals with recommendations for alcohol-related screening, brief intervention, and referral to treatment. MEDLINE and published reviews were used to identify relevant literature. Several brief screening methods have been shown to effectively identify underage drinkers likely to have alcohol use disorders. After diagnostic assessment when germane, the initial intervention typically focuses on education, motivation for change, and consideration of treatment options. Internet-accessible resources providing effective brief interventions are available, along with supplemental suggestions for parents. Recent changes in federal and commercial insurance reimbursement policies provide some fiscal support for these services, although rate increases and expanded applicability may be required to prompt the participation of many practitioners. Nevertheless, advances in clinical methods and progress on reimbursement policies have made screening and brief intervention for underage drinking more feasible in general health care practice.

Child abuse and other traumatic experiences, alcohol use disorders, and health problems in adolescence and young adulthood

OBJECTIVE

We prospectively examined the health effects of child abuse and other traumatic events, with objective health indicators and consideration of alcohol use disorders (AUD).

METHODS

Adolescents (n = 668) were recruited from clinical and community sources. At baseline, we examined child abuse and other traumas, AUD, health-related symptoms, physical findings, and blood assays. Subjects were assigned to Trauma Classes (TC), including witnessing violence, physical abuse, and sexual abuse. Health outcomes were again determined at 1-year and young adult follow-up.

RESULTS

In adolescence, higher TC severity was associated with more health-related symptoms, increased age-adjusted body mass index, and stress-response immune system indices. In adolescence and young adulthood, the relationships between TC and health-related symptoms were mediated by anxiety. AUD was associated with liver injury, and cigarette smoking with heart/lung symptoms.

CONCLUSIONS

Child abuse predicted persistently elevated health-related symptoms primarily attributable to anxiety, and early signs of liver disease were attributable to AUD.

The role of socioregional factors in moderating genetic influences on early adolescent behavior problems and alcohol use

BACKGROUND

Twin and family studies have demonstrated that adolescent alcohol use and behavior problems are influenced by a combination of genetic and environmental factors. More recently, studies have begun to investigate how genetic and environmental influences may interact, with efforts underway to identify specific environmental variables that moderate the expression of genetic predispositions. Previously, we have reported that community-level factors, including urban/rural residency, migration rates, and prevalence of young adults, moderate the importance of genetic effects on alcohol use in late adolescence (ages 16 to 18). Here, we extend these findings to test for moderating effects of these socioregional factors on alcohol use and behavior problems assessed in a younger sample of adolescent Finnish twins.

METHODS

Using data from the population-based Finnish twin study, FinnTwin12, biometric twin models were fit to data on >1,400 twin pairs to examine the significance of each of the socioregional moderating variables on alcohol use measured at age 14, and behavior problems, measured at age 12.

RESULTS

We find no evidence of a moderating role of these socioregional variables on alcohol use; however, there was significant moderation of genetic influences on behavior problems, with effects limited to girls. Genetic influences assumed greater importance in urban settings, communities with greater migration, and communities with a higher percentage of slightly older adolescents.

CONCLUSIONS

The moderation effects observed on behavior problems in early adolescence paralleled the effects found on alcohol use late in adolescence in an independent sample, providing further support for the idea that behavior problems may represent an earlier manifestation of the predisposition to subsequent alcohol problems. Our findings also support the growing body of evidence suggesting that females may be more susceptible to a variety of environmental influences than males.

Decreasing Prevalence of Alcohol Consumption Among Greek Adolescents

AIM OF THIS STUDY

To obtain data on alcohol consumption among school children of secondary education and to investigate any correlation to their health behaviors and parental socioeconomic status.

METHODS

A questionnaire was distributed to students from a representative sample of 15 schools from Thessaloniki, the second (after Athens) largest metropolitan city of Greece. A total of 1185 students (505 males, 680 females) participated.

RESULTS

286 males (56.6%) and 329 females (48.4%) reported consuming alcohol. The initiation of drinking was at the age of 13.2 years for boys and 13 years for girls. Alcohol drinking was positively associated with socio-demographic variables and negative health behaviors such as parental low level of education, lack of physical exercise, coffee consumption, and smoking.

CONCLUSIONS

Although our results show a decrease in alcohol use, which is more pronounced in male students, the prevalence of frequent alcohol consumption is among the highest in Europe's countries.

Practitioner review: adolescent alcohol use disorders: assessment and treatment issues

BACKGROUND

Alcohol use disorders in adolescents are associated with significant morbidity and mortality. Over the past decade, there has been a burgeoning of research on adolescent alcohol use disorders.

METHODS

A summary of the alcohol assessment tools is provided, and randomized studies reviewed and synthesized to provide an overview of state of the art knowledge of treatment of adolescent alcohol use disorders. Animal models of addiction are also briefly reviewed, and the value of translational research approaches, using findings from basic studies to guide the design of clinical investigations, is also highlighted.

RESULTS

Comorbidity is the rule, not the exception in adolescent alcohol use disorders. Comprehensive assessment of psychiatric and other substance use disorders, trauma experiences, and suicidality is indicated in this population to optimize selection of appropriate clinical interventions. In terms of available investigated treatments for adolescents with alcohol use disorders, Multidimensional Family Therapy and group administered Cognitive Behavioral Therapies have received the most empirical support to date. There is a paucity of research on pharmacological interventions in this patient population, and no firm treatment recommendations can be made in this area.

CONCLUSIONS

Given the high rate of relapse after treatment, evaluation of combined psychosocial and pharmacological interventions, and the development of novel intervention strategies are indicated.

Adolescent-onset substance use disorders predict young adult mortality

This study determined whether adolescent-onset substance use disorders (SUDs) prospectively predicted early mortality. Among 870 adolescents, 21 young adulthood deaths were observed. Adolescent SUDs, as well as gender, ethnic group, hazardous substance use, and drug trafficking, predicted these deaths. Among African American males with SUDs, 23% died by age 25.

Adolescent neurological development and its implications for adolescent substance use prevention

Recent technological advancements have facilitated the study of adolescent neurological development and its implications for adolescent decision-making and behavior. This article reviews findings from the adolescent neurodevelopment and substance use prevention literatures. It also discusses how findings from these two distinct areas of adolescent development can complement each other and be used to build more developmentally appropriate interventions for preventing adolescent substance use. Specifically, a combination of child-centered and family-based strategies is advocated based on extant neurological and prevention literature. EDITORS' STRATEGIC IMPLICATIONS: Researchers are encouraged to take up the authors' challenge and study the links between adolescent neurological development/decision making ability and the long term efficacy of comprehensive interventions for preventing adolescent substance use.

Medical student judgments of adolescents with alcohol use disorders (AUD)

The clinical encounter presents opportunities for detection and intervention of adolescent alcohol use disorders (AUDs).

AIMS

Investigate (a) identification rate of AUDs, (b) whether AUD identification predicts clinical judgment, and (c) patient characteristics influences on clinical judgment. Medical students (n=123) read a case study and completed questions on diagnosis and clinical judgment. Twenty-five percent of participants identified AUD adolescents, who were more negatively rated than non-AUD adolescents. Prior clinical experience and addiction training predicted AUD identification. Patient race and gender influenced clinical judgment ratings. Addictions training is needed to improve identification rates. Study limitations are noted.

Medical conditions of adolescents in alcohol and drug treatment: comparison with matched controls

PURPOSE

Alcohol and drug problems are associated with medical problems among adults. Research on the relationship of adolescent alcohol and drug use disorders to specific medical problems is less developed and focused on acute consequences. This study addresses gaps in the literature regarding medical comorbidities in adolescents with alcohol and drug use disorders.

METHODS

This study compares the prevalence of medical conditions among 417 adolescent alcohol and drug treatment patients with 2082 demographically matched controls from the same managed care health plan and examines whether comparisons vary among substance-type subgroups.

RESULTS

Approximately one-fourth of the comorbid conditions examined were more common among adolescent alcohol and drug patients than among matched controls, and several were highly costly conditions (e.g., asthma, injury). We also found that pain-related diagnoses, including headache and abdominal pain, were more prevalent among alcohol and drug patients.

CONCLUSIONS

Our findings point to the importance of examining comorbid medical and chemical dependency in both adolescent primary care and specialty care. Moreover, optimal treatment of many common medical disorders may require identification, intervention, and treatment of a substance use problem.

Alcohol use in families: a 15-year prospective follow-up study

AIMS

To study the prevalence of adolescents' problematic alcohol use and its parental predictors: drinking habits and socio-demographic factors.

DESIGN, SETTING, PARTICIPANTS AND MEASUREMENTS

Questionnaires were sent regularly to the same Finnish families (n = 1132) from the onset of pregnancy (in 1986-87) to the child's age of 15 years (in 2001-02) (n = 1028). There was a total of three follow-up points.

FINDINGS

At 15 years of age, 83% of girls and 79% of boys had used alcohol; 18% of boys and 14% of girls had been drunk more than once a month. The child's permanent separation from at least one biological parent was the strongest socio-demographic predictor of adolescents drinking. Fathers' present heavy drinking and parental early drinking were the best predictors of their children's problematic alcohol use at the age of 15.

CONCLUSIONS

Knowledge of fathers' alcohol use and its time of onset may be used to determine children who are at added risk of problematic alcohol use later in life. Special guidance, support and treatment can be targeted to these families.

Risk taking and recurrent health symptoms in Canadian adolescents

OBJECTIVE

Psychosomatic health symptoms are commonly experienced by young people and are associated with chronic health problems. This study examines reports of psychosomatic health symptoms during adolescence, and associations between adolescent risk-taking and the occurrence of these symptoms.

METHOD

A cross-sectional national health survey was performed in 2001/02 and involved 1746 young Canadians. Principal components analyses were used to derive a multiple risk-taking score. Multi-level regression models with individual participants (1st level) nested in schools (2nd level) were used to examine associations between individual then multiple risk-taking behaviors and psychosomatic symptoms.

RESULTS

37% of males and 48% of female students reported psychological health symptoms > once per week, while 30% of males and 41% of females reported somatic health symptoms. Strong associations were observed between individual risk-taking behaviors (cannabis use, other illicit drug use, drunkenness, smoking, unprotected sex) and psychosomatic health symptoms. A risk gradient was observed between multiple risk behaviors and these health symptoms. Youth who engaged in high levels of risk-taking behavior were two to four times more likely to report health symptoms.

CONCLUSION

Adolescent lifestyles that include risk-taking behavior are strongly associated with the occurrence of psychosomatic health symptoms. Collectively, these measures are useful clinical indicators of adolescent health status.

Cardiovascular risk factors in adolescents with alcohol use disorders

Among adults, chronic alcohol dependence is associated with cardiovascular disease (CVD). While it is unlikely that adolescents with alcohol use disorders (AUDs) would exhibit CVD, they might show elevated CVD risk factors. The purpose of this study was to compare CVD risk factors in adolescents with AUDs and an adolescent reference group. Adolescents with AUDs were recruited from treatment sources and reference adolescents were recruited from the community. Information about smoking behavior, exercise, and diet were gathered from interview and self-report measures. Body mass index and blood pressure were determined by physical exam and a blood sample was drawn to measure serum cholesterol and triglycerides. Compared with the reference group, adolescents with AUDs reported significantly more smoking, were less likely to report exercising regularly, and were less likely to report eating a balanced diet. Adolescents with AUDs were not more likely to be overweight or to exhibit hypertension, and lipid levels were also not significantly elevated. These results indicated that adolescents with AUDs endorsed problematic health behaviors while not yet exhibiting the consequences of these behaviors. Interventions focusing on health behaviors in conjunction with addiction treatment might help improve long-term health outcomes in adolescents with AUDs.

Alcohol use frequency as a screen for alcohol use disorders in adolescents

While screening tools have been developed to identify adolescents likely to have alcohol use disorders (AUDs), none of the available methods are optimal for general medical settings. This study explored the sensitivity and specificity of the frequency of drinking episodes in the prior month as an initial screen for AUDs. The subjects were 219 adolescents (ages 12 through 18) systematically recruited from the community, who participated in a baseline assessment as well as 1-year, 3-year, and 5-year follow-up visits. Subjects completed a self-report form indicating their frequency of use of different substances in the month prior to the assessment. DSM-IV AUD diagnoses were determined by SCID. At baseline, 10 of 219 subjects met DSM-IV criteria for an AUD. At a threshold of 3 or more drinking episodes in the past month, the screen was 90% sensitive, correctly classifying 9 of 10 AUD cases, and 83.7% specific, correctly classifying 175 of 209 cases without AUDs. The diminishing specificity of this screen over the follow-up assessments indicated that this method may be useful for adolescents, but not for young adults. These results indicate that an assessment of the frequency of alcohol use in the prior month provides an initial screen with acceptable sensitivity and specificity for use with adolescents.

Supervisory neglect and adolescent alcohol use disorders: effects on AUD onset and treatment outcome

BACKGROUND

While parental supervision has been demonstrated to influence adolescent alcohol involvement, lack of a threshold defining inadequate supervision and little study of DSM defined alcohol use disorders (AUDs) have limited clinical applications. Utilizing a four-item supervision scale, this study identified adolescents with inadequate supervision, and examined effects on AUD development and treatment outcome.

METHODS

Two groups of adolescent subjects (ages 14-17) were recruited: (1) a representative community sample of adolescents (n = 170) and (2) adolescents with AUDs from drug and alcohol or psychiatric treatment programs (n = 194). Supervision was determined by the adolescent's responses to items inquiring whether parents typically had knowledge of the adolescent's activities away from home, including with whom, where, when, and communication items. Adolescents with unusually low parental supervision (i.e., Supervisory Neglect) were identified by scale distributions. Follow-up assessments were conducted 1, 3, and 5 years after the initial assessment.

RESULTS

Among community subjects, adolescents with inadequate supervision were significantly more likely to drink alcohol in a variety of situations, were more likely to have AUDs at the initial assessment and, among those without AUDs, were more likely to develop AUDs in the follow-up period. Among adolescents receiving treatment for AUDs, those with inadequate supervision were less likely to be free of AUD symptoms over a 1-year follow-up period.

CONCLUSIONS

These results indicate that the described method was a straightforward and potentially clinically applicable approach to identifying adolescents with inadequate parental supervision.
