Age of initiation, intensity and cessation of tobacco smoking among Bangladeshi adults: evidence from a cross-sectional nationally representative survey.
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 smoking is a major global health issue, linked to nearly 8 million deaths annually. This study explores the smoking behaviors of adults in Bangladesh, focusing on the age of initiation, intensity, and cessation attempts.
methodsThe study is based on the data from the Global Adult Tobacco Survey, 2017-18, which comprised 12,774 respondents from Bangladesh aged 15 years and older. Statistical analyses included descriptive statistics, weighted t-tests, weighted ANOVA, Rao-Scott Chi-square tests, and regression models (Survey-weighted linear and negative binomial, Firth's penalized logistic) to assess determinants of smoking behaviors.
resultsAmong the respondents, 18.13% were tobacco smokers. Among smokers, 43.85% initiated tobacco use at or before age 18, 35.20% had a successful cessation attempt, and 10.78% were heavy smokers. Geographical division and education level were significant differentials for early initiation, smoking intensity, and successful cessation attempt. Lower paid working people including agriculture workers, daily laborers, and unemployed individuals able to work were associated with high smoking intensity. Gender and age of respondents were significantly associated with age of initiation but not with smoking intensity or cessation attempt. Residence and wealth index were not significant for any outcome.
conclusionThese findings emphasize the need for targeted tobacco control strategies in Bangladesh to address early initiation, high smoking intensity, and low cessation attempt rates. Analytical results highlight the need for tailored intervention programs and laws. Prioritize tobacco as an addictive substance and target lower paid working and less educated populations, along with high-burden regions such as Mymensingh, Chattogram, and Sylhet.
