Determinants and predictive modelling of barriers to HIV testing uptake among adolescents and young adults in a private higher education institution in Botswana.
Article in PloS one, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundHIV represents a significant public health challenge, contributing to increased mortality and morbidity in developing countries, particularly Sub-Saharan Africa. While HIV testing is crucial for early treatment and prevention, the uptake of the HIV testing among the adolescent and young adults in Botswana remains low. This study aims to predict barriers to HIV testing uptake among adolescents and young adults.
methodA quantitative cross-sectional study was conducted. Data was obtained using a questionnaire employing a simple random sampling technique to collect the survey data. Statistical analysis involved descriptive statistics and multivariable logistic regression.
resultsA total of 353 participants were recruited. The prevalence of HIV testing uptake in the preceding 12 months was (64.9%; n = 229). Determinants associated with non-uptake of HIV testing included participants in casual relationships (OR 1.776,95%CI 0.998-3.160, P < 0.049), transactional relationships (AOR 1.098, 95% CI 0.189-6.382) compared with single participants. Additional determinants included residence beyond 5 km from HIV testing centers (OR 1.825, 95% CI 1.074-3.103, P < 0.026), and cohabiting (AOR 3.45, 95% CI 0.271-43.979). Religious affiliation was also predictive, with Christians (AOR 2.347, 95% CI 0.188-29.295), Muslims (AOR 1.765, 95% CI 0.046-59.506), and adherents of African traditional religions (AOR 1.718, 95% CI 0.084-35.004) exhibiting higher odds of non-testing compared with non-believers. Participants with negative attitudes toward HIV testing were 69% less likely to forgo HIV testing (OR 0.310, 95% CI 0.1704-3.103, P = 0.026) than those with positive attitudes.
conclusionThis study provides critical evidence on disparities in HIV testing among adolescents and young adults in Botswana, highlighting persistent gaps in access and utilization. These findings underscore the necessity for context-specific strategies that mitigate access barriers and address behavioral, structural, and socio-cultural determinants to optimize HIV testing uptake, advancing progress toward the UNAIDS 2030 target of zero new infections.
