Parenting and School Context Differentiate Nigerian Adolescents’ Profiles of Substance Use

Abstract. Substance use among Nigerian adolescents has increased significantly in the past decade, highlighting the need to implement evidence-based, effective prevention programs as one strategy to help reverse this trend. This study aimed to identify profiles of adolescent substance use and parenting and school correlates of these profiles to inform preventive interventions. Latent class analysis identified four distinct use patterns in 2,004 adolescents (46% male; M = 14.8 years) attending public and private schools in Lagos. Low levels of use distinguished the Low Use class (92.1% of the sample), while use of alcohol, cigarettes, and codeine defined the Alcohol Use class (2.9%). Moderate to high use of tramadol and codeine without a prescription differentiated the Nonmedical Use class (2.8%), and high use of most substances defined the High Use class (2.1%). Males, older youth, and private school students engaged in the riskiest substance use. Students in the Low Use class compared to students in the High Use class were more likely to attend public schools and had parents who solicited less information from them but were more disapproving of substance use. Students in the Low Use class relative to students in the Alcohol Use class also were more likely to attend public schools and had parents who solicited less information but knew more about their child’s activities. These findings suggest that tailored preventive interventions with parents and adolescents could be useful and that more research is needed to understand how the private school context confers risk for substance use.
