BACKGROUND: The association of secondhand smoke with health-related quality of life (HRQoL) has only been known to a limited extent. This study aimed to determine both the association between home smoking (HS) and HRQoL of nonsmoking adults and their differential association by subgroups of gender and age, respectively.

METHODS: HRQoL was assessed with the Centers for Disease Control and Prevention HRQOL-4 tool. HS was measured by asking the number of cigarettes per day of other family member(s) usually consumed per day by other family member(s) anywhere inside the home. The generalized linear models, adjusting for confounders, were used to analyze a valid sample of 1,259 nonsmokers aged ≥20 years from the National Health and Nutrition Examination Survey 2005-2006.

RESULTS: After adjustments, higher HS was associated with lower general health (p=0.0285) and higher mentally unhealthy days (p=0.0370). However, this pattern differed by gender and age. While HS was associated with the inactive days due to physical and/or mental health (p=0.0106) for female nonsmokers, it was associated with general health (p=0.0174) and mentally unhealthy days (p=0.0146) for males. Among older adults (≥ 60 years) HS had no relationship to HRQoL but it did to general health (p=0.038) and inactive days due to physical and/or mental health (p=0.0100) for younger adults (20≤ and ≥60 years).

CONCLUSIONS: Exposure to secondhand smoke at home is associated with reduced HRQOL of nonsmokers, but apparently more strongly with mental health than physical health. Its association with HRQOL however differs according to the subgroups of gender and age.

Learning Objectives:
1. determine the association of home smoking with health-related quality of life of nonsmoking adults 2. find if there is any differential association between home smoking and HRQOL according to subgroups of gender and age.
