Rapid unplanned urbanization in large cities in Bangladesh causing unhealthy living conditions. Tobacco smoke is one of the components of indoor air pollution and health consequences of exposure to second hand smoke (SHS) are well established. Global Adult Tobacco Survey 2017 Bangladesh reported that 39% adults are exposed to SHS at home. However, characteristics of households with SHS exposure are not well investigated in urban settings of Bangladesh.

To find out the extent of tobacco smoke exposed home and their characteristics in different areas of Dhaka city.

A cross sectional study was conducted in three different urban settings (high, middle and low income areas) of Dhaka city in 2016. Systematic random sampling was used for selection of households from each of the areas. Data were collected from household head by face to face interview using a semi-structured questionnaire. A household was considered as exposed to tobacco smoke if anybody smoked inside home within last 30 days.

Information were collected from a total 441 household heads. Among the respondents 79.6% were male, and mean age (±SD) was 47.8 (±13.5) years. About half of the respondents (43.3%) had higher level of education (at least graduate) and 35% were service holder. Among the respondents 27.7% were current smoker. Overall, 23.4% home had tobacco smoking exposure within last 30 days. Tobacco smoking exposed home was higher in low income areas compared to high or middle income areas (20.4%, 35.9% and 43.7% respectively in high, middle and low income areas, P<0.001). Tobacco smoking exposed home was also higher in home with household head with no formal education (p<0.001).

The study showed one fourth of home exposed to SHS. Community based intervention and comprehensive awareness programs including smoke free home campaign is recommended to protect people from SHS at home in urban areas.
