Comprehensive HIV knowledge and associated factors among reproductive-age women: analysis of the Gambia Demographic and Health Survey 2019/2020

Abstract Introduction Globally, there are 37.7 million people living with human immunodeficiency virus (HIV). So far, there is no study done in Gambia which assessed comprehensive HIV knowledge and its associated factors. Therefore, this study aims to assess comprehensive HIV knowledge and its associated factors among reproductive-age women in Gambia. Objective To assess the prevalence of comprehensive HIV knowledge and its associated factors among reproductive-age women in Gambia. Methods The study used the Gambian Demographic and Health Survey, which was conducted from 21 November 2019 to 30 March 2020 in Gambia. The survey employed a stratified two-stage cluster sampling technique to recruit study participants. Logistic regression analysis was used to identify factors associated with HIV comprehensive knowledge. Statistical significance was declared at a P value of less than 0.05 with a 95% confidence interval (CI). Results The overall prevalence of comprehensive HIV knowledge was 27.1% (25.1–36.2%). Older age [adjusted odds ratio (AOR) of 1.20 (95% CI 1.16–1.26)], using contraceptive [AOR of 1.15 (95% CI 1.01–1.31)], higher education [AOR of 4.73 (95% CI 3.86–5.81)], rich wealth quintile [AOR of 1.61 (95% CI 1.37–1.87)], media exposure [AOR of 1.76 (95% CI 1.39–2.23)], ever tested for HIV [AOR of 1.55 (95% CI 1.42–1.74)], visited health facility within the last 12 months [AOR of 1.26 (95% CI 1.12–1.41)] and decision-making autonomy [AOR of 1.42 (95% CI 1.27–1.60)] were positively associated with comprehensive HIV knowledge. However, being married [AOR of 0.72 (95% CI 0.62–0.82)] was negatively associated with comprehensive HIV knowledge. Conclusions The prevalence of comprehensive HIV knowledge was low in Gambia. Educational interventions that focused mainly on awareness creation about HIV/AIDS should be designed especially for married women and lower socio-economic status. An effort has to be made to address those disparities at the national level.
