title: Secondhand tobacco smoke exposure in low-income children and its association with asthma.
abstract: Secondhand tobacco smoke (SHS) is a common indoor environmental exposure that is particularly prevalent in low-income families. It has been found to be associated with asthma in some studies; however, across all relevant studies, results have been conflicting. This study aimed to determine the prevalence of SHS exposure in the home environment in a low-income, minority population and to determine the association of exposure with childhood asthma, wheeze, and oral corticosteroids use. This retrospective study analyzed self-reported data collected as part of the Kansas City Safe and Healthy Homes Partnership to determine prevalence of SHS exposure. A logistic regression model was then used to assess the association between exposure and asthma, oral steroid use, and wheeze. Overall, 40% of children lived with at least one smoker and 15% of children lived with at least one smoker who smoked inside the house. No significant association was found between asthma or oral corticosteroid use and SHS exposure. Children who lived with a smoker had a 1.54 increased odds of wheeze in the past year. A large percentage of low-income children in the Kansas City area continue to suffer the adverse effects of SHS. These data support the need for innovative public policy to protect children from such exposure in their home environment.
