Age of Substance Use Initiation and Sexual Violence Victimization among Female Adolescents

Objective: In this study, I examined the association between age of substance use initiation and sexual violence (SV) among adolescent girls. Methods: Data were drawn from the 2017 Youth Risk Behavior Survey, and the sample included 7526 girls. Logistic regression was used to estimate the relationship between age of initiation of alcohol use, marijuana use and cigarette smoking, and SV, assessed by forced sexual intercourse and experiencing SV. Results: A dose-response association was observed between age of substance use initiation and SV. Across all 3 substance use variables and for both SV outcomes, those who initiated substance use before age 15 were more likely to experience SV than those who initiated at or after age 15, who, in turn, had a higher likelihood of experiencing SV than those who had never initiated substance use. Conclusion: Early initiation of substance use may be a meaningful marker of risk for SV victimization in later adolescence. SV prevention programs could use early initiation of substance use to identify adolescents who are at increased risk for SV and provide them with targeted interventions. To be more effective, primary prevention of SV may need to begin targeting substance use in early adolescence.

School Climate as a Universal Intervention to Prevent Substance Use Initiation in Early Adolescence: A Longitudinal Study

Initiation of substance use often starts during adolescence, with tobacco and alcohol use frequently preceding the use of marijuana and other illicit drugs. Studies suggest that a positive school climate may prevent substance use while promoting healthy student behaviors. The purpose of this study was to determine the longitudinal associations between school climate and substance use initiation in a group of middle school students. Parallel latent growth curve modeling was used to examine changes among study variables longitudinally using a sample of 2,097 sixth-, seventh-, and eighth-grade students across 16 regional schools located in three counties in West Virginia. Results suggest that a positive school climate may prevent substance use initiation (β = −0.07 to −0.25, p < .01). However, perceptions of school climate decreased on their own over time (β = −0.28 to −0.66, p < .01). Furthermore, substance use initiation also increased as students grew older (β = 0.96 to 0.99, p < .01) and reduced the effects of school climate longitudinally (β = −0.07 to −0.24, p < .01). Early substance use initiation may be a warning sign of other underlying student issues and requires additional school support to foster student success. Findings suggest that a positive school climate may delay substance use initiation and promote school success. School climate may, therefore, be useful as an intervention to support school-based health promotion.
