The authors evaluated the effect of maternal cigarette smoking and alcohol drinking as a possible risk factor for febrile convulsion in a large cohort of pregnant women. Participants included 11,826 women enrolled in the Child Health and Development Studies in California between 1959 and 1966. Women were divided into non-smokers (n= 7,587) and smokers (n= 4,239). Unadjusted odds ratio (OR) for smoking showed increased risk of febrile convulsion (OR= 1.20, 95% CI = 0.93, 1.55) that did not vary across levels of cigarette smoking (p-value for the trend = 0.99). Cox proportional hazard model, which assumed changes in hazard function with time, indicated that children of smokers are at a greater risk of febrile convulsion than those of non-smokers during the first 800 days of life, after adjusting for maternal alcohol drinking, husband smoking during pregnancy, infantís sex, birth weight, severe congenital anomaly, and history of diarrhea and otitis media (OR = 1.37, 95% CI = 1.01, 1.87). The results also showed 2.1 times greater hazard associated with maternal smoking among children of those who are heavy drinkers (95% CI = 1.31, 3.26) during the first 800 days.
