Epidemiological evidence shows that children's exposure to secondhand
tobacco smoke increases their risk of respiratory illness. This study
evaluated five families and their asthmatic children (aged 5-14 years)
in an outpatient counseling program for reducing the children's expos
ure to passive smoking. Intervention included biweekly counseling/inst
ructions for parents to limit their children's tobacco exposure. A mul
tiple-baseline, quasiexperimental design was used for self-reported me
asures of the children's smoke exposure and the parents' smoking frequ
ency. Counseling was associated with smoke exposure reduction of 40-80
% from baseline for each of 5 children, with most improvements sustain
ed during follow-up. This study provides support for the development o
f tobacco exposure prevention programs for children with pulmonary dis
ease.
