Second-hand smoke exposure and household smoking bans in Chinese families: a qualitative study.

As workplace smoking restrictions spread, smoking in the home is becoming the predominant source of exposure to second-hand smoke (SHS) among children and other non-smokers in the household. This study explored issues around children's exposure to SHS. Focus group discussions (FGDs) and in-depth interviews (IDI) were conducted among 31 Chinese households in urban Shanghai, China. All FGDs/IDIs were audio recorded and analysed thematically. The findings suggest that there are gaps in knowledge of the health consequences of smoking and SHS among the participants. Although there was a lack of knowledge about the health risk of exposure to SHS, most were willing to protect their child from the SHS exposure. In 16/31 households, families had partial home-smoking restrictions; there were no complete restrictions in any of the smokers' homes. Many families do not openly discuss smoking or smoking restrictions at home. Barriers to adopting a smoke-free home included the social acceptability of smoking (22/31), hosting social gatherings at home, which would involve smoking (12/31), authoritative attitudes of the husband or father-in-law (10/31), and difficulties with visitors who smoke (7/31). Most (28/31) participants stated they would accept a counselling intervention to reduce SHS exposure to children and suggested various measures to implement it. The findings from this intervention have implications for designing intervention strategies to reduce SHS exposure at home among children in China.
