Prevalence and correlates of tobacco use among adolescents in Dhaka, Bangladesh: a cross-sectional study.
Article in BMC 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
backgroundTobacco use among adolescents in low- and middle-income countries is a public health concern. This study investigated the prevalence and correlates of ever and current tobacco use among adolescents in Dhaka, Bangladesh.
methodsA cross-sectional survey was conducted among school-going adolescents aged 11–18 years in schools across Dhaka city between June and September 2022, using an opportunistic sampling approach. A structured questionnaire collected data on socio-demographics, tobacco use behaviours, exposure to second-hand smoke (SHS), tobacco advertising, and anti-tobacco education. Logistic regression analyses were performed to identify correlates of tobacco use, adjusting for confounders.
resultsA total of 2,593 adolescents participated in the survey (mean age: 15.6 years, SD = 1.6); 55.6% (n = 1,442) were male. Ever and current tobacco use prevalence was 16.0% (95% Confidence Interval [CI]: 14.6–17.5) and 7.3% (95% CI: 6.3–8.3), respectively. Cigarette smoking was the most common form of tobacco use (10.4%, 95% CI: 9.3–11.7, reported ever use), followed by smokeless tobacco (7.6%, 95% CI: 6.7–8.7) and non-cigarette smoked tobacco (3.3%, 95% CI: 2.7–4.0). Males had higher odds of both ever (Adjusted Odds Ratio [AOR]: 1.75, 95% CI: 1.33–2.28) and current tobacco use (AOR: 4.12, 95% CI: 2.43–6.99) compared with females. Adolescents aged 17–18 years were more likely to be current users than those aged 11–13 years (AOR: 3.27, 95% CI: 1.36–7.85). Exposure to SHS at home and tobacco advertising at points of sale were significantly associated with higher odds of both ever (AOR: 1.65, 95% CI: 1.27–2.16 and AOR: 1.61, 95% CI: 1.23–2.11, respectively) and current tobacco use (AOR: 1.75, 95% CI: 1.19–2.59 and AOR: 1.59, 95% CI: 1.07–2.36, respectively). In contrast, receiving anti-tobacco education was associated with lower odds of ever (AOR: 0.71, 95% CI: 0.52–0.99) and current tobacco use (AOR: 0.52, 95% CI: 0.33–0.84).
conclusionTobacco use is prevalent among school-going adolescents in urban Bangladesh. Exposure to SHS and tobacco advertising are positively associated with tobacco use, while anti-tobacco education is negatively associated, underscoring the need for strong tobacco control measures in Bangladesh.
