Estimating the Effect of Depression on HIV Transmission Risk Behaviors Among People Who Inject Drugs in Vietnam: A Causal Approach 2020-08-24 .txt text/plain 5329 242 41 title: Estimating the Effect of Depression on HIV Transmission Risk Behaviors Among People Who Inject Drugs in Vietnam: A Causal Approach Depression may be an important driver of continued HIV transmission among PWID if symptoms increase transmission risk behaviors (e.g., sharing injection drug use equipment, engaging in condomless sex) in the absence of viral suppression. In the main analysis, we used marginal structural models to estimate the average causal effect of severe depressive symptoms on the risks of any injection equipment sharing or any condomless sex (separately) in the period three to 6 months later, controlling for time-fixed and time-varying confounders. In our main analysis, we estimated that severe depressive symptoms (compared to no or mild symptoms) increased the risk of sharing injection equipment by 3.9 percentage points (RD = 3.9%, 95% CI −1.7%, 9.6%) and decreased the risk of condomless sex by 1.8 percentage points (RD = −1.8%, 95% CI −6.4%, 2.8%) in the period three to 6 months later (Table 2, Fig. 1 ). ./cache/cord-012503-8rv2xof7.txt ./txt/cord-012503-8rv2xof7.txt
