Individual, interpersonal, organizational, and community contexts: factors associated with alcohol consumption among Brazilian adolescents.
Article in BMC pediatrics, 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
backgroundAdolescence is a development period characterized by biological, psychological, and social changes that may lead to risk behaviors, such as alcohol consumption. Family, school, and community contexts, together with exposure to different communication media, may contribute to adolescents' vulnerability to alcohol use.
objectiveTo identify individual, interpersonal-, organizational-, and community-level factors associated with current alcohol consumption among Brazilian adolescents.
methodsWe conducted a cross-sectional study using data from the 2019 National Survey of School Health (PeNSE). The outcome was current alcohol consumption (use in the past 30 days). Poisson regression with robust variance was employed to estimate prevalence ratios (PR) and their respective 95% confidence intervals (95% CI), including factors from individual, interpersonal, organizational, and community levels.
resultsTwenty-eight point one percent of Brazilian adolescents reported alcohol consumption. At the individual level, alcohol use was positively associated with age 16-17 years (PR = 1.54), cigarette smoking (PR = 1.47), use of other tobacco products (PR = 2.04), illicit drug use (PR = 1.21), regular consumption of sugar-sweetened foods (PR = 1.20), feeling sad (PR = 1.29), and thought that life was not worth living (PR = 1.24). At the interpersonal level, alcohol consumption was associated with parental alcohol consumption (PR = 1.66), parental concern about the adolescent (PR = 1.05), intrafamilial physical violence (PR = 1.09), sexual violence (PR = 1.15), and truancy (PR = 1.23). At the community level, higher prevalence was observed in the South (PR = 1.27).
conclusionsWe observed a high prevalence of current alcohol consumption among Brazilian adolescents, associated with factors across multiple contextual levels, highlighting the complexity and multidimensional nature of this behavior.
