Global burden of active smoking among people living with HIV on antiretroviral therapy: a systematic review and meta-analysis.

Background: Although the high burden of both active smoking and human immunodeficiency virus (HIV) is clearly known, the relationship between them is still not well characterized. Therefore, we estimated the global prevalence of active smoking in people living with HIV (PLHIV) on antiretroviral therapy (ART) and investigated the association between exposure to active smoking and risk for suboptimal adherence to ART. Main text: We searched PubMed, Embase, and Web of Science to identify articles published until September 19, 2019.
