Zusammenfassung: | Objectives
Adherence to antiretroviral therapy (ART) leads to viral suppression for people living with HIV (PLHIV) and is critical for both individual health and reducing onward HIV transmission. HIV stigma is a risk factor that can undermine adherence. We explored the association between HIV stigma and self‐reported ART adherence among PLHIV in 21 communities in the HPTN 071 (PopART) trial in Zambia and the Western Cape of South Africa.
Methods
We conducted a cross‐sectional analysis of baseline data collected between 2013 and 2015, before the roll‐out of trial interventions. Questionnaires were conducted, and consenting participants provided a blood sample for HIV testing. Poor adherence was defined as self‐report of not currently taking ART, missing pills over the previous 7 days or stopping treatment in the previous 12 months. Stigma was categorised into three domains: community, health setting and internalised stigma. Multivariable logistic regression was used for analysis.
Results
Among 2020 PLHIV self‐reporting ever taking ART, 1888 (93%) were included in multivariable analysis. Poor ART adherence was reported by 15.8% (n = 320) of participants, and 25.7% (n = 519) reported experiencing community stigma, 21.5% (n = 434) internalised stigma, and 5.7% (n = 152) health setting stigma. PLHIV who self‐reported previous experiences of community and internalised stigma more commonly reported poor ART adherence than those who did not (aOR 1.63, 95% CI 1.21 −2.19, P = 0.001 and aOR 1.31, 95% CI 0.96–1.79, P = 0.09).
Conclusions
HIV stigma was associated with poor ART adherence. Roll‐out of universal treatment will see an increasingly high proportion of PLHIV initiated on ART. Addressing HIV stigma could make an important contribution to supporting lifelong ART adherence.
Objectifs
L'adhésion à la thérapie antirétrovirale (ART) conduit à la suppression virale pour les personnes vivant avec le VIH (PVVIH) et est essentielle à la fois pour la santé individuelle et pour réduire la transmission du VIH. La stigmatisation du VIH est un facteur de risque qui peut compromettre l’adhésion. Nous avons exploré l'association entre la stigmatisation du VIH et l'adhésion autodéclarée à l’ART chez les PVVIH dans 21 communautés dans l'essai HPTN 071 (PopART) en Zambie et dans le Western Cape en Afrique du Sud.
Méthodes
Nous avons effectué une analyse transversale des données de base collectées entre 2013‐2015, avant le déploiement des interventions d'essai. Des questionnaire |
