Description
Summary:OBJECTIVES: To assess the prevalence of smoking and of caffeine and alcohol intake during pregnancy in a northern population and to determine the relation of these factors to birth weight, length and head circumference. DESIGN: Questionnaire survey and collection of maternal and newborn measurements. SETTING: Ten communities in the Inuvik Zone, NWT. PATIENTS: A total of 162 women (56 Inuit, 38 Indian, 37 white and 31 mixed race) who presented for prenatal care in their community and gave birth in Inuvik between September 1987 and January 1990 and their newborns. RESULTS: In all, 64% (101/159) of the women smoked, 57% (88/154) ingested more than 300 mg of caffeine daily, and 34% (50/145) drank alcohol during their pregnancy. Smoking, caffeine intake and binge drinking were most frequent among the Inuit and Indian mothers. Smoking was significantly associated with decreased birth weight (p less than 0.001) and length (p less than 0.05). Alcohol intake, especially binge drinking, was significantly associated with decreased head circumference (p less than 0.05). Caffeine was found not to be related to any of the outcome variables after smoking was controlled for through stepwise multiple regression. CONCLUSIONS: The marked prevalence of smoking and alcohol intake during pregnancy and their effects on the newborn are public health concerns in the Northwest Territories and warrant intensive countermeasures.
