The role of maternal smoking as a causal factor for the incidence of childhood asthma is still not clearly established.
It was investigated among 3-and 4-year-old-child incident cases confirmed by a 6-year follow-up (n=294) and cases who no longer had symptoms after diagnosis (n=110).
The study took place in Montréal, Canada, between 1988 and 1997.
Persistent and transient cases were compared with their respective controls from the original case-control study of incidence.
The odds ratio for heavy maternal smoking adjusted for known risk factors for asthma was 3.84 (95% confidence interval : 1.68,8.76) among persistent cases and close to one among transient cases.
