The impact of place of residence on antiretroviral therapy adherence: A systematic review and meta-analysis

Objective: There is evidence of geographical variation in HIV coverage and antiretroviral therapy (ART) adherence, and studies have investigated how the place of residence of people living with HIV (PLWH) influences ART adherence. Where people reside influences their access to health care. Studies on the influence of place of residence on ART adherence among PLWH in Nigeria have been reported in the literature. However, no review has synthesized these findings. Against this backdrop, this review seeks to determine whether adherence to ART differs by place of residence in Nigeria. Methods: In May 2024, we searched four databases (CINAHL Plus, PubMed, Scopus, and Web of Science). Only empirical studies with a test of association between place of residence (i.e., urban and rural) and adherence to ART were included. We performed a fixed-effect meta-analysis with the meta package on R Studio Version 4.2.0. Results: We included six of the 91 articles across the four databases. Most studies (n = 5) were conducted in the Southern region. The assessment of place of residence and adherence varies across the studies. We found that PLWH who reside in urban areas were 20% more likely to adhere to ART compared to those who live in rural areas (odds ratio: 1.20; 95% confidence interval: 1.01-1.43). Similarly, PLWH in the South-South region of Nigeria and reside in the urban areas were 1.27 (95% CI: 1.01-1.58) more likely to adhere to ART than those living in the rural areas. This observation was insignificantly true for the South-East region. Conclusion: PLWH who reside in urban areas may better adhere to ART than their counterparts living in rural areas. Non-governmental organizations and government agencies working with PLWH should prioritize those living in rural areas because they are more likely to face greater barriers to adherence.
