Trends in Substance Use by Gender Among Participants in a Jail-Based Substance Use Disorder Treatment Program: 1998-2016.

Understanding trends in substance use by gender among jail-based treatment program participants can inform policies and programs tailored to this population. Preprogram assessment data from 3509 individuals entering a jail-based substance use disorder treatment program in Missouri between 1998 and 2016 were analyzed. Primary outcome was program participants' strongly preferred substances. Demographic covariates and drug preferences were compared between males and females. Average yearly trends in preferred substances were calculated. While 25.8% of the sample preferred heroin, it was more strongly preferred by women (36.4%) than men (22.0%, p < 0.0001). Alcohol and marijuana were preferred more by males. Overall, preferences for heroin and methamphetamine increased over time while alcohol, marijuana, and other stimulants decreased. Women being more likely to prefer heroin and the increasing preference for heroin over time are consistent with national trends. Offering evidence-based treatment like pharmacotherapy and gender-sensitive approaches can help address the needs of this vulnerable population.
