Advising parents of asthmatic children on passive smoking : randomised controlled trial.
Objective To investigate whether parents of asthmatic children would stop smoking or alter their smoking habits to protect their children from environmental tobacco smoke.
Design Randomised controlled trial
Setting Tayside and Fife, Scotland.
Participants 501 families with an asthmatic child aged 2-12 years living with a parent who smoked.
Intervention Parents were told about the impact of passive smoking on asthma and were advised to stop smoking or change their smoking habits to protect their child's health.
Main outcome measures Salivary cotinine concentrations in children, and changes in reported smoking habits of the parents 1 year after the intervention.
Results At the second visit, about 1 year after the baseline visit, a small decrease in salivary cotinine concentrations was found in both groups of children : the mean decrease in the intervention group (0.70 ng/ml) was slightly smaller than that of the control group (0.88 ng/ml), but the net difference of 0.19 ng/ml had a wide 95% confidence interval (-0.86 to 0.48).
Overall, 98% of parents in both groups still smoked at follow up.
However, there was a non-significant tendency for parents in the intervention group to report smoking more at follow up and to having a reduced desire to stop smoking.
Conclusions A brief intervention to advise parents of asthmatic children about the risks from passive smoking was ineffective in reducing their children's exposure to environmental tobacco smoke. (...)
