Risky sexual behaviours and associated factors among high school students in Lomé, Togo: A cross-sectional study.
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
backgroundAdolescent sexual and reproductive health remains a major public health concern in sub-Saharan Africa. In Togo, evidence on risky sexual behaviours (RSBs) among in-school adolescents is limited. This study examined patterns of RSB and associated sociodemographic, relational, and digital factors among high school students in Lomé.
methodsA cross-sectional study was conducted from December 2023 to March 2024 among 461 high school students aged 15-23 years. Participants were selected through multistage sampling and completed a structured, self-administered questionnaire. RSB was defined as reporting at least one of the following: inconsistent condom use, overlapping sexual partnerships, substance-influenced sex, or casual sexual encounters. Descriptive statistics and logistic regression analyses were used to examine patterns and associated factors.
resultsNearly half of respondents (47.3%) reported sexual intercourse during the past 12 months. Among sexually active students, 58.7% reported sexual debut before age 18, 56.4% inconsistent condom use, 40.8% overlapping sexual relationships, and 27.5% coerced first sex. Gendered patterns were observed, with females more likely to report coerced first sex, older partners, and transactional sex. In adjusted analyses, higher odds of RSB were associated with personal mobile phone ownership (AOR = 11.35, 95% CI: 3.11-41.34), sexual debut at age 18 or older (AOR = 5.54, 95% CI: 1.55-19.82), and coerced first sex (AOR = 5.84, 95% CI: 1.15-29.49). Lower odds were observed among students with one to two agemates in the household (AOR = 0.23, 95% CI: 0.05-0.98), those identifying with other religions (AOR = 0.07, 95% CI: 0.01-0.37), and those living alone (AOR = 0.04, 95% CI: 0.00-0.39).
conclusionsRSBs among high school students in Lomé highlight gaps in sexual health literacy, consent negotiation, condom-use skills, and online safety. Strengthening comprehensive sexuality education, integrating digital literacy into school curricula, and expanding gender-responsive, youth-friendly SRH interventions are essential to promote safer, informed, and equitable adolescent sexual practices in Togo.
