Sociodemographic and health systems determinants of antiretroviral therapy adherence among human immunodeficiency virus-positive patients in the Volta Region of Ghana: A multi-centre study.

Objectives: Optimal adherence to antiretroviral therapy is required for viral load suppression. This study investigated the sociodemographic (age, sex, marital status, level of education, monthly income, settlement type, distance to the antiretroviral therapy-providing site, ethnicity) and health system (antiretroviral therapy-providing site) determinants of antiretroviral therapy adherence among human immunodeficiency virus-positive patients in the Volta Region, Ghana.

Methods: A cross-section design was adopted, collecting data from 1729 human immunodeficiency virus patients and analysing them using STATA version 17 at level 0.05.

Results: Antiretroviral therapy adherence was poor (51.2%). Being divorced (Adjusted odds ratio (AOR) = 0.65), widow (AOR = 0.58), cohabiting (AOR = 0.22), Ewe (AOR = 3.7), Ga/Dangbe (AOR = 2.27), living in a rural area (AOR = 1.54) and an urban area (AOR = 0.64), having a monthly income of GH₵1000 or less (AOR = 3.21), covering a distance of 51 km and above to the antiretroviral therapy centre (AOR = 1.79), receiving antiretroviral therapy from Ketu South Municipal Hospital (AOR = 0.09), Hohoe Municipal Hospital (AOR = 0.03), Ho Municipal Hospital (AOR = 0.02) and Ho Teaching Hospital (AOR = 0.09) were the determinants of antiretroviral therapy adherence.

Conclusion: Antiretroviral therapy adherence was low. Interventions to improve antiretroviral therapy adherence should target these significant determinants.
