Child abuse and neglect: Relations to adolescent binge drinking in the national longitudinal study of Adolescent Health (AddHealth) Study

The purpose of this study was to examine the relationship between child maltreatment and adolescent binge drinking. Given that many victimized children have been maltreated in multiple ways, we examine the effects of co-occurrence of multiple types of maltreatment on adolescent binge drinking. We used the National Longitudinal Study of Adolescent Health (AddHealth), which included a nationally representative sample of adolescents (n=12,748). Adolescent binge drinking was defined as five or more drinks in a row at least 2-3 times per month in the past year. Among those reporting any maltreatment, 12.4% reported binge drinking compared to 9.9% among those reporting no maltreatment. Logistic regression models found that child maltreatment is a robust risk factor for adolescent binge drinking controlling for parental alcoholism. In particular, all types of or combinations of types of maltreatment were strongly associated with adolescent binge drinking, controlling for age, gender, race, parental alcoholism and monitoring. Research examining the effect of childhood maltreatment on later alcohol abuse needs to recognize the clustering effects of multiple types of childhood maltreatment on alcohol problems.

A longitudinal examination of childhood maltreatment and adolescent obesity: Results from the National Longitudinal Study of Adolescent Health (AddHealth) Study

OBJECTIVES We sought to explore the association between childhood maltreatment (e.g., neglect, physical and sexual abuse) and longitudinal growth trajectories of body mass index (BMI) from adolescence to young adulthood. METHODS We used latent curve modeling to examine data from the National Longitudinal Study of Adolescent Health (N=8,471), pooling years 1995-2008. Relative weight was indicated by BMI. RESULTS Children who experienced neglect had a faster average rate of BMI growth over time compared to children who experienced no childhood maltreatment. In addition, the co-occurrence of childhood neglect and physical abuse was related to increased levels of BMI at baseline, even after adjustment for 14 separate child and parental demographic and psychosocial characteristics. Parental obesity and education, child birth place, and family income were also associated with both baseline BMI and the rate of change in BMI over time. CONCLUSION Childhood neglect plays a role in the development of adolescent obesity. Future research should examine potential mediators or moderators of the longitudinal relation between childhood neglect and adolescent and young adult obesity including impulsivity, depression, and compulsive eating behavior.

Personality and alcohol use: The role of impulsivity

Research has shown that personality traits associated with impulsivity influence alcohol use during emerging adulthood, yet relatively few studies have examined how distinct facets of impulsivity are associated with alcohol use and abuse. We examine the influence of impulsivity traits on four patterns of alcohol use including frequency of alcohol use, alcohol-related problems, binge drinking, and alcohol use disorders (AUDs) in a community sample of young individuals (N=190). In multivariate regression analyses that controlled for peer and parental alcohol use, psychological distress, and developmental correlates (i.e., college, marriage, employment) in emerging adulthood, we found that urgency and sensation seeking were consistently related to all four constructs of alcohol use. The present study suggests that distinct impulsivity traits may play different roles in escalation of alcohol use and development of AUDs during emerging adulthood.

Childhood sexual abuse and adolescent substance use: A latent class analysis

Children who have exposure to child sexual abuse (CSA) are at particular risk for developing substance abuse in adolescence, but the extent to which CSA may shape patterns of adolescent substance use remains uncertain. The aim of this paper is to characterize the variations in patterns of adolescent substance use and to examine the association between CSA and qualitatively distinct patterns of adolescent substance use. Latent class analyses identified homogenous groups of adolescents with similar patterns of substance use using a sample of 1019 adolescents (mean age: 15.9 years; range: 13-18) who were selected from five publicly funded service systems. Different patterns of latent class structures were identified in boys and girls (a 4-class solution for girls and a 3-class solution for boys). CSA was associated with an increased risk of being a heavy polysubstance user in girls, even after adjustment of age, race/ethnicity, parental substance use, sibling use, peer use, psychopathology and other forms of childhood maltreatment including physical abuse and neglect. Findings indicate that female victims of CSA who are involved with public service systems are at high risk for developing multiple-substance use in adolescence.

Exposure to childhood neglect and physical abuse and developmental trajectories of heavy episodic drinking from early adolescence into young adulthood

BACKGROUND Although the literature suggests that childhood maltreatment (CM) relates to adolescent heavy episodic drinking (HED), few studies have examined the long-term effects of CM on adolescent HED. This study is the first to examine associations between exposure to CM and trajectories of HED from adolescence to young adulthood for the US population. METHODS Four waves of data from the National Longitudinal Study of Adolescent Health were used. A total of 8503 adolescents followed from adolescence (7th-12th grades) into young adulthood (ages 24-32) were assessed on CM and past-year HED frequency. Using growth curve modeling, trajectories of adolescent HED were examined, with subtype, frequency, and severity of CM as the primary independent variables. All of our analyses controlled for common risk factors for adolescent HED, including demographics, parental and peer alcohol use, parental education and employment, family income, parent-child relationship, and adolescent depression. RESULTS After controlling for potential risk factors, neglect and physical abuse, both individually and in conjunction, were associated with faster increases in HED during adolescence and persistently elevated HED over much of adolescence and young adulthood. The frequency of neglect and physical abuse, individually and in conjunction, was also associated with the trajectory of HED, such that additional instances of these types of maltreatment were associated with faster increases in HED during adolescence and higher rates of peak use during young adulthood. CONCLUSION Child neglect and physical abuse appear to have long-lasting adverse effects on HED beyond adolescence and throughout much of young adulthood.

Developmental Outcomes of Vulnerable Youth in the Child Welfare System

Abstract Adolescent development of youth in foster care holds great interest for society. This article examines a random sample of 200 adolescents currently placed in foster care on developmental outcomes. Using face-to-face interviews, the present study found that a majority of foster youth have biological families experiencing multiple problems and experience many developmental difficulties. A large percentage of the sample youth experience mental illness, school failure, substance abuse, and other antisocial behaviors. This paper considers implications from the study findings for policy and interventions designed to foster better developmental outcomes among youth in the child welfare system.

Relationship between Multiple Forms of Maltreatment by a Parent or Guardian and Adolescent Alcohol Use

This study examined the effect of the co-occurrence of multiple categories of maltreatment on adolescent alcohol use. Data were from the National Longitudinal Study of Adolescent Health which used a nationally representative sample of adolescents (n = 14,078). Among those reporting any maltreatment, over one-third had experienced more than one type of maltreatment. Logistic regression models found that all types or combinations of types of maltreatment except physical-abuse-only were strongly associated with adolescent alcohol use, controlling for age, gender, race, and parental alcoholism. These results add to accumulating evidence that child maltreatment has a deleterious impact on adolescent alcohol use.

An Examination of Pathways from Childhood Maltreatment to Adolescent Binge Drinking

Considerable clinical and empirical evidence has accumulated over the past decades indicating that there is a strong association between childhood maltreatment and heavy episodic drinking in adolescence, but there is a paucity of empirically based knowledge about the processes linking the association. The aim of this paper is to examine mechanisms that might account for the association between childhood maltreatment and heavy episodic drinking in adolescence. Using a nationally representative sample of adolescents (ages ranging 12-21; N = 6,337), this study examined the role of individual self-regulatory processes in the associations, controlling for age, gender, race/ethnicity, peer substance use, parental alcoholism, and parent-child conflict. Factor analyses were used to test the measurement structure of self-regulatory processes. Findings confirmed the association between childhood maltreatment and heavy episodic drinking in adolescence. Structural modeling analyses indicated indirect effects for childhood maltreatment primarily through poor self-regulatory processes and peer substance use. Implications for future research are discussed.

A Longitudinal Examination of the Relationships between Childhood Maltreatment and Patterns of Adolescent Substance Use among High‐Risk Adolescents

BACKGROUND Childhood maltreatment has been linked to adolescent substance use in cross-sectional studies but the studies were unable to test the associations between childhood maltreatment and changes in substance use patterns during adolescence. The present study investigated the linkages between exposure to childhood maltreatment and developmental trends of alcohol, cannabis, cocaine, opioid, and hallucinogen use among high-risk adolescents. METHODS We used a sample of 937 adolescents (mean age: 15.9 years; range: 13-18), who were selected from five publicly-funded service systems, to examine the extent to which childhood maltreatment may influence changes in patterns of adolescent substance use over time. RESULTS The present study identified a 3-class model of adolescent substance use. Mover-stayer latent transition analyses (LTA) indicated that progression toward heavy polysubstance use increased with experience of childhood maltreatment. Findings also suggested that older male adolescents (ages 15-18) who are involved with public service systems are at high risk for developing and maintaining multiple-substance use in adolescence. CONCLUSIONS Experience of childhood maltreatment is associated with problematic patterns of adolescent substance use and may shape the longitudinal course of substance use during adolescence.

Examining Drug Treatment Entry Patterns Among Young Injection Drug Users

Using a longitudinal state data base, 1996–2002, of all Injection Drug Users (IDU) (n = 37,227) admissions to all state-licensed drug treatment programs, this study examined differences in drug treatment entry patterns between younger IDUs (ages 18–25) compared to middle-age IDUs (ages 26–39) and older IDUs (over 40 years of age). Most of the younger IDUs were male, unemployed, and dependent on heroin. After controlling for factors known to affect type of drug treatment entered, younger IDUs were significantly more likely than their older counterparts to only use detoxification services and not enter additional treatment. Further, younger IDUs were significantly less likely to enter methadone maintenance and significantly more likely to enter residential treatment compared to older IDUs. Development of strategies to promote transition from detoxification to more comprehensive treatments and especially to methadone maintenance treatment is warranted.
