Tobacco control

To determine the extent of all forms of tobacco usage in adult Bangladeshis in relation to gender and locality. ⋯ Nearly a third of the population in Bangladesh use some form of tobacco. There are marked urban-rural and male-female differences. This difference is mainly accounted for by the higher prevalence of chewing tobacco in rural areas, rural female tobacco usage is close to double than the urban rate. Smoking rates were low in Bangladeshi females, more so in urban than rural areas. The tobacco awareness programme in Bangladesh might require putting emphasis on smokeless tobacco as well as smoking.

To examine the prevalence of smoke-free homes in England between 1996 and 2007 and their impact on children's exposure to second-hand smoke via a series of annual cross-sectional surveys: the Health Survey for England. These comprised nationally representative samples of non-smoking children aged 4-15 (n = 13 365) and their parents interviewed in the home. Main outcome measures were cotinine measured in saliva, smoke-free homes defined by "no" response to "Does anyone smoke inside this house/flat on most days?", self-reported smoking status of parents and self-reported and cotinine validated smoking status in children. ⋯ There has been a marked secular trend towards smoke-free homes, even when parents themselves are smokers. Living in a smoke-free home offers children a considerable, but not complete, degree of protection against exposure to parental smoking.

Given that little is known about the price-related cigarette brand preferences of youths, the current study seeks to characterise cigarette brand preferences and examine factors associated with smoking discount or native cigarette brands among Canadian youths who are current smokers. ⋯ Discount and native cigarette brands are commonly used by a substantial number of smoking youths in Canada. Additional research is required to better understand the reasons behind different cigarette brand preferences and how youths are able to access premium, discount and illicit native cigarettes. Moreover, ongoing surveillance of the cigarette brand preferences of youths is required for guiding future tobacco control policy and programming activities.
