Perceived social support moderates the association between household dysfunction adverse childhood experiences (ACEs) and self-reported drug use among men who have sex with men in Los Angeles, California.

BACKGROUND

Adverse childhood experiences (ACEs) have been shown to be associated with drug use in adulthood. The single ACE of household substance use history (part of the household dysfunction category) has frequently been associated with drug use. Resilience factors such as perceived social support appear to buffer the association between ACEs and drug use and may be particularly relevant for urban men who have sex with men (MSM). The current study of low-income mostly Black and Latino MSM aims to investigate whether the cumulative ACE score predicts self-reported drug use in a dose-response manner and whether this potential association differs by perceived social support.

METHODS

Data was utilized from a longitudinal study of MSM (mean age=34; SD=7.1) with varied substance use behaviors (n = 321) collected between August 2014 and April 2022. Cumulative, household dysfunction ACEs, and the single ACE of household substance use history were investigated as predictors of self-reported drug use (methamphetamine, ecstasy, cocaine/crack, heroin/fentanyl, party drugs [GHB, special K, mushrooms, LSD/acid], other drugs [bath salts, PCP]) during the past six months in mixed-effects logistic regression models, with moderation analyses by perceived social support (measured by the Multidimensional Scale of Perceived Social Support) across all models using stratified analysis and one model of multiplicative interaction.

RESULTS

There was no suggestion of a dose-response relationship between the number of ACEs and the predicted probability of self-reported drug use. Cumulative ACEs did not predict the outcome overall (aOR=1.99; 95% CI: 0.86-4.59), however, a positive association was estimated for individuals reporting lower levels of perceived social support (aOR=2.80; 95% CI: 0.97-8.06). The dimension of household dysfunction had a positive association with drug use (aOR=1.32; 95% CI: 1.00-1.74) whereas the dimension of childhood maltreatment did not. The association between household dysfunction and drug use was moderated by the perception of social support, with those reporting lower levels having greater odds of reporting drug use (aOR=2.94; 95% CI: 1.04-8.31). The association between household substance use history and self-reported drug use was similarly moderated by perceived social support in a multiplicative interaction model (p = .02).

CONCLUSION

Perceived social support emerged as a potential buffering factor for any reported drug use, particularly for the single ACE of household substance use history. Given that the association between ACEs and drug use was weak among those with higher levels of perceived social support, promotion of social ties in the community may help reduce the burden of substance use among MSM exposed to ACEs.
