Body image and antiretroviral therapy adherence among people living with HIV: a protocol for a systematic review and meta-analysis

Introduction Adherence to antiretroviral therapy (ART) remains a key challenge to achieving the fast-track goal of ending the HIV epidemic by 2030. To provide a more comprehensive indication of whether interventions designed to promote ART adherence might benefit from targeting body image perceptions, we aim to conduct a systematic review to synthesise existing evidence on the association between body image and ART adherence. Methods and analysis A systematic review of peer-reviewed observational studies and randomised controlled trials that have investigated the association between body image and adherence to ART will be performed. JSTOR, PsycARTICLES, PsycINFO, PubMed, ScienceDirect and Web of Science databases will be searched from 1 January 2000 to 31 March 2021. Eligible records will consider body image as either an independent variable or a mediator, whereas ART adherence will be assessed as an outcome variable. Study selection will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and study quality will be assessed using relevant tools developed by the National Institute of Health. If sufficient data are available, a meta-analysis will be conducted. Effect size estimates will be aggregated using a random effects meta-analysis approach. Publication bias and its impact will be evaluated through the use of a funnel plot and the trim-and-fill method. The Grading of Recommendations Assessment, Development and Evaluation approach will be used to report on the overall quality of evidence. Ethics and dissemination Ethical approval is not required for a systematic review protocol. Findings of the proposed systematic review will be disseminated through conference presentations and publication in a peer-reviewed journal. PROSPERO registration number CRD42020212597.
