Exposure to environmental tobacco smoke among Missouri children.

Childhood exposure to environmental tobacco smoke (ETS) increases the risk of lower respiratory infections (e.g., bronchitis and pneumonia), exacerbates childhood asthma, and increases the prevalence of fluid in the middle ear. Using self-reported telephone survey data, we examined the attitudes and practices of Missouri residents related to ETS exposure of children. Ninety-five percent of all respondents believed that ETS exposure is harmful to children and the percentage was similar for households with children (96%) and without children (94%). ETS was present in 42% of households and the percentage was similar for households with children (41%) and without children (44%). Childhood exposure to ETS remains a problem in Missouri, despite widespread awareness of the hazards. More active intervention is needed to reduce ETS exposure in the home.
