Smoking behaviour in young families. Do parents take practical measures to prevent passive smoking by the children?
OBJECTIVE: To investigate smoking behaviour in young families. DESIGN: Cross-sectional study. SETTING: Mother and child health centres in Oslo, Norway. SUBJECTS: The families of 1,046 children attending the health centres for 6-weeks-, 2- or 4- year well child visits. MAIN OUTCOME MEASURES: Daily smoking, smoking quantity and practical measures taken by the parents to prevent passive smoking among the children as assessed by parental reports. RESULTS: In 48% of the families at least one adult was smoking. 33% of the smoking parents smoked more than ten cigarettes per day. 47% of the smoking families reported that they did not smoke indoors. CONCLUSIONS: The parents were less likely to smoke if they were more than 35 years of age, had a child aged less than one year, had a spouse/co-habitee or had a long education. Smoking parents smoked less if they had a spouse/co-habitee, had a child aged less than one year or had few children. Smoking parents were more often careful and did not smoke indoors if they had a child aged less than one year, had a spouse/co-habitee, did not have a smoking spouse/co-habitee or smoked a low number of cigarettes per day.
