A population-based hospital survey of 3628 women in the postpartum period was conducted in the Ottawa-Carleton region in 1983 to determine the prevalence of smoking before and during pregnancy, the demographic and socioeconomic characteristics of women who smoke during pregnancy and the use of health care services by these women. Of the 3628 women 91% completed a full-length questionnaire and 4% completed a shorter questionnaire. Before pregnancy 37.4% of the women smoked cigarettes. Overall, 61.1% of the smokers changed their smoking habit: 31.1% stopped, 28.1% decreased the amount smoked and 2.0% increased the amount smoked. Two thirds of the women who stopped smoking did so as soon as they realized they were pregnant. Over 50% of teenagers, single women, women living common-law and women with less than a grade 11 education smoked after the 3rd month of pregnancy. The physician is in an ideal position to identify as soon as possible pregnant women who smoke and to initiate a health education program. Only a few women who smoked during pregnancy attended early prenatal classes. Physicians and class organizers must work to improve this situation if such classes are to have an impact on smoking during pregnancy.
1983年，在渥太华-卡尔顿地区对3628名产后妇女进行了一项基于人群的医院调查，以确定怀孕前和怀孕期间吸烟的患病率、孕期吸烟妇女的人口统计学和社会经济特征，以及这些妇女对医疗保健服务的使用情况。在这3628名妇女中，91%完成了完整问卷，4%完成了简短问卷。怀孕前，37.4%的妇女吸烟。总体而言，61.1%的吸烟者改变了吸烟习惯：31.1%戒烟，28.1%减少吸烟量，2.0%增加吸烟量。三分之二戒烟的妇女在意识到自己怀孕后就立即戒烟。超过50%的青少年、单身女性、同居女性以及受教育程度低于11年级的女性在怀孕第三个月后仍在吸烟。医生处于理想的位置，能够尽快识别出吸烟的孕妇并启动健康教育项目。只有少数孕期吸烟的妇女参加了早期产前课程。如果此类课程要对孕期吸烟产生影响，医生和课程组织者必须努力改善这种情况。
