HIV stigma and depressive symptoms are related to adherence and virological response to antiretroviral treatment among immigrant and indigenous HIV infected patients

Abstract

We compared adherence to cART and virological response between indigenous and immigrant HIV-infected patients in the Netherlands, and investigated if a possible difference was related to a difference in the psychosocial variables: HIV-stigma, quality-of-life, depression and beliefs about medications. Psychosocial variables were assessed using validated questionnaires administered during a face-to-face interview. Adherence was assessed trough pharmacy-refill monitoring. We assessed associations between psychosocial variables and non-adherence and having detectable plasma viral load using logistic regression analyses. Two-hundred-two patients participated of whom 112 (55%) were immigrants. Viral load was detectable in 6% of indigenous patients and in 15% of the immigrants (P < 0.01). In multivariate analyses, higher HIV-stigma and prior virological failure were associated with non-adherence, and depressive symptoms, prior virological failure and non-adherence with detectable viral load. Our findings suggest that HIV-stigma and depressive symptoms may be targets for interventions aimed at improving adherence and virological response among indigenous and immigrant HIV-infected patients.
