Sociodemographic factors associated with acceptance of index case testing among newly diagnosed human immunodeficiency virus-positive clients in southern borno, Nigeria

Abstract

Background The study aimed to explore the sociodemographic factors associated with the acceptance of index case testing (ICT) among newly diagnosed people living with HIV (PLHIV) in Southern Borno, Nigeria. Methods The study involved four healthcare facilities providing antiretroviral therapy (ART) services in Southern Borno, Nigeria. Secondary data from the index case testing register were collected between April 2022 and April 2023. Categorical variables were analyzed using descriptive statistics, while bivariate and multiple logistic regression analyses was used to determine the factors associated with ICT acceptance, using a 95% confidence interval and significance level of p ≤ .05. Results Among the 302 index cases offered ICT, the acceptance rate was 69.5%. Individuals aged 25–49 years (AOR: 0.294, 95% CI: 0.098–0.775) and 50 years and above (AOR: 0.210, 95% CI: 0.046–0.862) were less likely to accept ICT compared to those aged 18–24 years. Married individuals were 38.86 times more likely to accept ICT than those who were single and never married (AOR: 38.856, 95% CI: 12.620–171.674). Conclusion The study shows high ICT acceptance among newly diagnosed PLHIV in Southern Borno, with age and marital status as significant factors. These findings can guide targeted interventions to enhance ICT acceptance and enhance HIV care and prevention strategies in the region.
