Factors Related to Biological Sex Differences in Engagement with Healthcare Providers in Persons Living with HIV.

Little is known about how engagement with healthcare providers mediates the relationship between psychosocial factors (anxiety, depression, stigma) and medication adherence among persons living with HIV (PLWH). Moreover, little research has investigated potential biological sex differences in this relationship. We conducted a secondary analysis of data collected from four projects (N = 281) focused on improving health outcomes in PLWH. Males displayed (a) negative association between depression and engagement with healthcare providers (β = - 0.02, z = - 3.20, p = 0.001) and (b) positive association between engagement with healthcare providers and medication adherence (β = 0.55, OR = 1.73, z = 2.62, p = 0.009). Females showed no association between any of these factors. Anxiety and stigma were not significantly associated with medication adherence. Path analysis modeling for males had a very good fit (CFI = 1, TLI = 1, RMSEA = 0); none of the regression coefficients was significant for females. The significant relationship between depression and medication adherence among males was fully mediated by engagement with healthcare providers. Findings suggest that adherence interventions for PLWH should be tailored by biological sex.
