Prevalence of tobacco use and its contributing factors among adolescents in Bangladesh: Results from a population-based study

Abstract
Background: Tobacco use is an alarming public health problem worldwide and causes significant morbidity and mortality. In many developing countries tobacco use starts at a relative younger age. However, data on tobacco use among adolescents in Bangladesh is scarce. Objectives: The main objective of this study was to estimate the prevalence of tobacco use and its contributing factors among adolescents in Bangladesh. Materials and Methods: We used data from the Global Youth Tobacco Survey (GYTS) Bangladesh 2007 which was a school-based survey of 2,135 students aged 13-15 years in grades 7-10. Analysis: A two-stage cluster sample design was used to produce representative data for Bangladesh. At the first stage, schools were selected with probability proportional to enrollment size. At the second stage, classes were randomly selected and all students in selected classes were eligible to participate. The GYTS sample design produced representative, independent, cross-sectional estimates for Bangladesh. Results: The overall prevalence of ever cigarette smokers in Bangladeshi students was about 9%, which was more than 3 times higher in boys compared to girls (15.8% versus 4.8%). Almost 4 in 10 students start smoking before the age of 10 in Bangladesh. In addition to current cigarette smoking, another 6% also reported to use other tobacco products currently. Nine in 10 current smokers reported that they had ever received help to stop smoking. More than 4 in 10 students were exposed to smoke from other people in public places. Among current smokers, 38.3% reported that they usually buy tobacco in a store and of which 97.8% reported that they were not refused cigarette purchase because of their age. Conclusion: Implementation and enforcement of tobacco control act is an urgent public health priority in Bangladesh.
