Alcohol use among adolescents in eight sub-Saharan African countries: evidence from the Global School-based student health survey (2012-2017) using the socio-ecological model.
Article in BMC psychiatry, 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
backgroundAlcohol use is a major global public health issue due to associated negative physical, mental, and social health outcomes among adolescents. This study examined the current alcohol use, drunkenness, and alcohol problems and associated correlates among 16,331 adolescents from eight selected sub-Saharan African countries.
methodsA secondary analysis of the Global School-based Student Health Survey (GSHS) datasets from eight cross-sectional surveys was conducted. The STATA statistical software package (Version 17) was used for the data analysis. Chi-square and multivariate logistic regression analyses were conducted with statistical significance set at p-value < 0.05.
resultsWe found that the overall prevalence of current alcohol use, drunkenness, and alcohol-related problems among adolescents was 12.56%, 8.32%, and 4.74%, respectively. Seychelles recorded the highest rates of current alcohol use (47.21%) and lifetime drunkenness (42.17%), while Tanzania reported the lowest for both (2.89% and 1.41%, respectively). The highest prevalence of alcohol-related problems was observed in Namibia (13.76%), with the lowest again in Tanzania (1.89%). Risk factors associated with alcohol use behaviours included male gender, older adolescent age (15-18 years), mental health challenges (anxiety, loneliness, suicidal behaviours), and psychosocial issues (truancy, bullying, fighting, physical attacks, lack of close friends, hunger, cigarette and marijuana use). However, peer support and positive parenting emerged as protective factors.
conclusionThis study highlights the urgency of addressing alcohol use behaviours among adolescents, taking into cognizance the prevalence and country-level variations. Multilevel vulnerability and resilience factors consistent with the socio-ecological model were identified, and they should be incorporated into school-based public health interventions to reduce the risk and burden of alcohol use among adolescents in SSA.
