Coverage and determinants of HIV testing and counseling services among mothers attending antenatal care in sub-Saharan African countries: a multilevel analysis.

BACKGROUND: HIV/AIDS is one of the top global public health threats that causes significant cases, deaths, and socioeconomic impact. Even though both HIV testing and counseling are identified as essential HIV interventions during pregnancy, large population-representative data shows that service coverage and determinants are limited. Therefore, this study aimed to assess the coverage and determinants of HIV testing and counseling services among pregnant mothers attending antenatal care services in sub-Saharan African countries using different nationwide data.

METHODS: This study was conducted on large national-representative data from the Demographic Health Survey (DHS) using multilevel analysis. Data extraction, cleaning, coding, and statistical analysis were performed using STATA version 17. Weighting was used to ensure the representativeness of the sample and to obtain reliable estimates and standard errors. The multivariable multilevel logistic regression model was used to identify the determinants of HIV testing and counseling during the antenatal care visit. Adjusted odds ratios with 95% confidence intervals were used to measure statistical significance.

RESULTS: A total of 83,584 women attending antenatal care were included in this study. HIV testing and counseling coverage in sub-Saharan Africa was found to be 62.87% with a 95% CI of 62.54-63.19%. The HIV testing and counseling determinants included being in the age group of 35-49 (AOR = 1.64; 95% CI: 1.46-1.83), secondary and above education levels (AOR = 1.50; 95% CI: 1.39-1.60), having at least four ANC visits (AOR = 1.85; 95% CI: 1.68-2.02), living in an urban area (AOR = 1.40; 95% CI: 1.30-1.52), and living in countries such as Rwanda (AOR = 6.19; 95% CI: 5.19-7.38) and Mauritania (AOR = 0.02; 95% CI: 0.01-0.03).

CONCLUSION: This study revealed that HIV testing and counseling coverage was 62.87% in sub-Saharan Africa. Factors affecting the HIV testing and counseling coverage were age, education, frequency of antenatal care visits, residence area, and living in Rwanda and Mauritania. Therefore, to increase HIV testing and counseling coverage in sub-Saharan Africa, policymakers on maternal health and other stakeholders should work with an integrated approach with other sectors and give prior attention to modifiable factors such as promoting women's education and the comprehensiveness of antenatal care follow-up services during the follow-up.
