This study, conducted among men who have sex with men (MSM) in sub-Saharan Africa (SSA), sought to replicate the syndemic effects of psychosocial health problems on HIV risk by using data collected from a sample of 300 MSM and bisexuals from Tanzania. We also sought to test the utility of syndemic theory by replicating the effects of the number of syndemic conditions on HIV risk behavior in that population.
Five psychosocial health problems (i.e., the syndemic factors), acronymized as SAVID, were examined: substance use while having condomless sexual intercourse, childhood and adolescent sexual abuse, experience of anti-gay violence, internalized homonegativity (IH), and depression. Nine of the 10 odds ratios (ORs) generated from analysis of the bivariate associations between these syndemic factors were found to be statistically significant and positive; the tenth was marginally significant and positive. These results indicate not only a high degree of coexistence of the syndemic factors but also suggest that possible interactions between these factors may have additive effects on the behavioral health outcomes of the study participants. Such additive effects were confirmed by finding a “dose-response†relationship between HIV risk-associated sexual behavior and the number of the five syndemic factors reported by each participant. After controlling for demographic and contextual factors, we found that the SAVID syndemic variable significantly increased the odds of engaging in condomless sexual intercourse (OR, 1.48). This substantiates the central tenet of syndemic theory, which is that those participants who were exposed to a greater number of the psychosocial health problems also engaged in higher-risk sexual behavior.
Multivariate regression analyses revealed not only the effect of two of the syndemic conditions (substance use during sex and IH) on HIV risk-related sexual behavior but also confirmed how one demographic variable (younger age) and one culturally structured factor (being gay but still having a meaningful sexual relationship with women) uniquely contributed to syndemic conditions among Tanzanian MSM.
These results suggest that a multifaceted HIV intervention grounded in syndemic theory should be considered as an effective approach to mitigating the risk environment that potentiates the vulnerability to HIV among Tanzanian MSM.
