Abstract

OBJECTIVE: To determine the prevalence of smoking during pregnancy in Nova Scotia and to identify women at high risk of smoking during pregnancy. DESIGN: Population-based descriptive study. SETTING: All hospitals providing obstetric services in Nova Scotia. PATIENTS: All 60 754 women residing in Nova Scotia who had a baby in hospital between 1988 and 1992; smoking data were available for 57,750 (95.1%) of them. OUTCOME MEASURES: Proportion of women who smoked during pregnancy and the maternal smoking rates by age, marital status, parity, attendance at prenatal classes and residence. RESULTS: Overall, 32.4% of the women smoked at some point during their pregnancy. The rate was highest among the women less than 20 years of age (47.0%) and decreased with each increasing 5-year age interval. Overall, the unmarried women were 2.1 times as likely to smoke as the married women. The smoking rates were highest among the women who were para 3 or greater regardless of age (women less than 20 were excluded here, since very few had such a parity). Of the nulliparous women, those who attended prenatal classes were less likely to smoke during pregnancy than those who did not attend. There was no relation between urban or rural residence and smoking rates. The smoking rates decreased little between 1988 and 1992 and in fact increased among the women 35 and over and among those who were para 3 or greater. CONCLUSIONS: The smoking rates among pregnant women in Nova Scotia changed little between 1988 and 1992. Therefore, it seems that current strategies for smoking cessation have not been successful. Since prenatal classes are more likely to attract nonsmokers than smokers, other avenues for education and cessation are necessary.
