    Abstract:
    OBJECTIVES: This study examined the relationship between maternal tobacco and alcohol consumption during the first trimester of pregnancy and oral clefts. METHODS: Data were derived from a European multicenter case-control study including 161 infants with oral clefts and 1134 control infants. RESULTS: Multivariate analyses showed an increased risk of cleft lip with or without cleft palate associated with smoking (odds ratio [OR] = 1.79, 95% confidence interval [CI] = 1.07, 3.04) and an increased risk of cleft palate associated with alcohol consumption (OR = 2.28, 95% CI = 1.02, 5.09). The former risk increased with the number of cigarettes smoked. CONCLUSIONS: This study provides further evidence of the possible role of prevalent environmental exposures such as tobacco and alcohol in the etiology of oral clefts.
