Sexual behavior and its influencing factors among Uruguayan adolescents: a cross-sectional study.
Article in AJOG global reports, 2025. 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: This study aimed to investigate the factors influencing adolescent sexual behavior in Uruguay, with a focus on socio-demographics, substance use, psychological distress, and protective factors. Methods: We analyzed data from the 2019 Uruguay Global School-based Student Health Survey (GSHS). Chi-square tests identified variables significantly associated with sexual behavior. Mixed-effects logistic regression models estimated odds ratios, and a fully adjusted model provided adjusted odds ratios for all significant factors. All analyses were performed using R programming. Result: Our analysis included a total of 2495 participants. Older adolescents (≥15 years) had a significantly higher likelihood of engaging in sexual behavior (AOR: 3.69, 95% confidence intervals [CI]: 2.92-4.66). Tobacco (AOR: 2.60, 95% CI: 1.91-3.55) and alcohol use (AOR: 2.09, 95% CI: 1.71-2.56) were strong risk factors, along with alcohol-related behavioral issues (AOR: 2.08, 95% CI: 1.65-2.62). Anxiety (AOR: 1.51, 95% CI: 1.09-2.08) and involvement in physical fights (AOR: 1.84, 95% CI: 1.42-2.40) increased the odds, while loneliness showed a protective effect (AOR: 0.62, 95% CI: 0.46-0.83). Parental bonding (OR: 0.54, 95% CI: 0.45-0.65), attachment (OR: 0.70, 95% CI: 0.59-0.82), and supervision (OR: 0.64, 95% CI: 0.54-0.77) showed significant effects before adjustment, but after adjustment, they became insignificant. Sedentary behavior reduced the likelihood, while truancy increased the possibility of sexual behavior among adolescents. Conclusion: Interventions should aim to reduce adolescent sexual risk behaviors by promoting healthy practices and addressing factors such as substance use, mental health, and parental involvement to encourage safer sexual behaviors.
