- Abstract
Adolescent sexual minority males (ASMM) are among the highest risk groups for suicide in the United States, with substance use as a significant risk factor. We tested for an association between substance use and suicidality among ASMM from the 2015 and 2017 Youth Risk Behavior Survey (n = 849). We compared several approaches to synthesizing measures of marijuana, cocaine, heroin, ecstasy, methamphetamines, synthetic marijuana, and prescription drug abuse, including several categorized and continuous indices, latent class analysis based on any use of each substance, and latent profile analysis based on use frequency. Using all approaches, substance use was positively associated with suicide attempts independent of covariates. A continuous cumulative index was the best fit to our data (quasi-information criterion = 853.9969) and detected the largest association, with the highest prevalence of suicide attempts among ASMM who used all substances compared with those who used none (adjusted prevalence ratio = 3.35, 95% confidence interval: 2.41, 4.66). A 3-latent-class model had the second best fit to the data (quasi-information criterion = 878.4464), with the highest prevalence of suicide attempts (adjusted prevalence ratio = 2.54, 95% confidence interval: 1.80, 3.57) among the high-substance-use class compared with the low-use class. Substance use is an especially important focal point for targeted interventions reducing suicidality among ASMM.
