The prevalence of substance use in child welfare and general population eighth graders in the United States

Abstract

Background: Early substance use is an established risk factor for substance abuse and dependence. Objective: The current study sought to examine whether child welfare-involved eighth graders have higher rates of early substance use than general population eighth graders. Data from the first National Survey of Child and Adolescent Well-Being (NSCAW) were analyzed to assess the prevalence of self-reported substance use, including alcohol, marijuana, and inhalant use in child welfare-involved eighth graders (N = 896). These figures were compared to general eighth grade student population estimates from the Monitoring the Future Study (N = 16,900) using 95% confidence intervals (CIs). Finally, regression analyses were conducted to examine demographic predictors (i.e., age, gender, race/ethnicity, and out-of-home placement) of substance use among child welfare eighth graders. Results: Results indicated comparable or lower incidence of substances among child welfare eighth graders relative to the general population, but higher past 30-day inhalant use among child welfare youth in out-of-home placement (17.1%, 95% CI: 6.0%, 40.2%) than the general population (4.2%, 95% CI: 3.7%, 4.7%). Out-of-home placement was associated with higher inhalant use (lifetime β = .659, p = .034; 30-day β = .763, p = .040) and alcohol use (lifetime β = .415, p = .028). Conclusions/Importance: These findings imply the need for screening and prevention education about substance use in child welfare populations, particularly in regards to inhalant use.
