Healthy Family Project: Tobacco Use and Smoke Exposure in Asian American Communities

Recruiting now · Not applicable

Conditions studied: Tobacco-Related Carcinoma, Smoking Cessation

In brief

This study evaluates whether the Smokefree Family Living (SFL) intervention improves quit rates (smoking cessation) and exposure to tobacco contamination that stays in items such as, carpets, walls, and furniture, even after the smoke has cleared (third-hand smoke (THS)) among Chinese American smokers and their non-smoking household members. Smoking remains high among Chinese American males with limited ability to speak English. This causes the non-smoking household members to be exposed to THS, which contains many of the same harmful components as smoking and becomes more toxic as it ages. SFL is tailored for Chinese Americans and combines the contents of the Quit Smoking for a Healthy Family (QS) intervention with additional THS education and cleaning strategies. QS focuses on smoking cessation through educational sessions and support. THS education and cleaning strategies provide information on THS and how to clean the home for THS. SFL may help Chinese American smokers and their non-smoking household members learn about the importance of quitting and the dangers of THS, this may improve smoking cessation and reduce THS exposure
