Abstract
HIV self-testing (HIVST) offers an alternative to facility-based voluntary counseling and testing (VCT) services, particularly for vulnerable populations such as adolescents. This study aimed to determine the sociodemographic factors associated with adolescents preferring home-based HIVST over facility-based VCT in Kisangani, Democratic Republic of the Congo. A representative cross-sectional study using random sampling in clusters at three levels was conducted among adolescents (aged 15–19 years) to assess their hypothetical preference in home-based HIVST over facility-based VCT by a face-to-face, paper-based, semi-structured questionnaire, and logistic regression for statistical analysis. In 353 households, 754 adolescents were assessed for eligibility, of whom 628 were eligible. A total of 597 adolescents completed the study questionnaire. A majority of participants were aged 18–19 and of female gender. More than two-thirds of participants had never been tested for HIV and had no knowledge about HIVST before this survey. Among 597 adolescents who had completed the study questionnaire, a slight majority of participants (323/597; 54.1% [95% CI: 50.0–58.0]) preferred home-based HIVST over facility-based VCT. In a multivariate analysis, male gender (adjusted OR: 1.5, 95% CI: 1.1–2.1), marriage or partnered civil status (adjusted OR: 1.8, 95% CI: 1.1–3.1), and previous knowledge about HIVST (adjusted OR: 4.2, 95% CI: 2.6–6.8) were associated with preference for home-based HIVST over facility-based VCT. This study demonstrates that more adolescents preferred home-based HIVST over facility-based VCT in Kisangani. These observations suggest the existence of a specific sociodemographic profile associated with the acceptance of HIVST in adolescents living in sub-Saharan Africa.
