About this trial

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

Trial outcomes

Primary outcomes

1

Proportion of participants who have quit smoking at 6 months

The smoking cessation rate is defined as the proportion of smokers who report quitting smoking, with biochemically verified 30-day point prevalent abstinence at the 6-month follow-up. Smoking rates will be reported by arm.

Time frame
6 months

Secondary outcomes

1

Change in levels of tobacco smoke biomarkers for second-(SHS)hand smoke exposure

The change in level of tobacco smoke exposure will be assessed among non-smoking family/household members by reviewing levels of urinary 4-(Methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL) at baseline and at 6 months.

Time frame
Up to 6 months
2

Proportion of participants who have quit smoking at 12 months

The smoking cessation rate is defined as the proportion of smokers who report quitting smoking, with verified 30-day point prevalent abstinence by biochemical markers (e.g., urinary NNAL and cotinine tests) at the 12-month follow-up. Smoking rates will be reported by arm.

Time frame
Up to 12 months
