Motivation, social support, and knowledge of parents who smoke and who have children with asthma

Motivation to quit smoking, social support and knowledge of asthma were investigated in a group of parents (n = 39) who smoked and whose children had asthma. Parents who reported smoking only outside the house had higher rankings on a motivation to quit smoking measure than parents who reported smoking inside the house. Parents who smoked had less knowledge of asthma when compared to parents who did not smoke. Parents who smoked and reported joining a smoking cessation program had more knowledge of asthma than parents who smoked but did not join cessation programs. Analysis of urinary cotinine in the children revealed no associations between urinary cotinine and motivation to quit smoking, social support and/or knowledge of asthma.
