Efforts to quit smoking by parents of children with asthma.

The objective of this project was to assess the prevalence of (1) tobacco smoke exposure at home among children with asthma and (2) efforts to quit smoking by their parents. We employed a cross sectional survey of 622 parents of children diagnosed by a doctor with asthma. Seventy-five percent of parents reported smoke-free homes. Overall, 85% of parents pledged to keep smoke-free homes, 92% in existing smoke-free homes and 64% in homes with smoke.
