Prevalence and correlates of risky sexual behaviour among in-school adolescents in Bulawayo, Zimbabwe: a cross-sectional study.
Article in BMJ public health, 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
Background: Adolescents are a key target for sexual health interventions because risky sexual behaviour (RSB) raises public health concerns, including sexually transmitted infections and unintended pregnancies. In Bulawayo, Zimbabwe, rising HIV rates among adolescents highlight the need for targeted research. This study aims to assess the prevalence of RSB among in-school adolescents and identify associated sociodemographic and sexual health educational factors. Methods: An analytical cross-sectional survey was conducted among 314 adolescents aged 13-19 from four randomly selected high schools in Bulawayo Central. A self-administered, structured questionnaire was used to collect data on sexual behaviours, knowledge and risk factors. Data were analysed using descriptive statistics, χ² tests and multivariable logistic regression to identify significant predictors of sexual activity. Prevalence estimates are reported with 95% CIs. Results: The analysis revealed that 52 of 314 respondents (16.6%, 95% CI 12.5% to 21.4%) reported ever having engaged in sexual intercourse. A higher prevalence was observed among males (28/122, 23.0%) over females (24/192, 12.5%). Adolescents in Forms 5-6 were more likely to engage in sexual activity (adjusted OR (AOR) 3.46, 95% CI 1.24 to 9.63, p=0.018), and those living with a single parent were also at increased risk (AOR 2.56, 95% CI 1.13 to 5.81, p=0.024). Among the 52 sexually active respondents, 38 (73.1%) reported unprotected sex at last intercourse, with higher rates among females (22/26, 84.6%) compared with males (16/26, 61.5%) (p=0.049). Although 268 participants (85.4%) reported receiving sexual health education, only 149 (47.5%) found it sufficient and 296 (94.3%) desired safe spaces for discussion. Conclusion: There is a significant gap between sexual health knowledge and safe practices, necessitating interventions that build skills, address communication gaps and foster supportive school environments to reduce RSB.
