Pregnant smokers comprise a distinct subgroup for smoking cessation intervention. Today, between 20% and 30% of women smoke during pregnancy. Among the many who do manage to quit successfully during the prenatal period, 70-90% have relapsed by one year postpartum despite a prolonged period of abstinence. Clearly, intense efforts in encouraging smoking cessation during pregnancy have resulted in, at best, temporary abstinence, but have failed to generate long-term improvements in women’s health. More effective smoking cessation programs must be developed to help pregnant and postpartum women quit and maintain their abstinence. Within the category of ‘pregnant smoker’, diverse subpopulations exist, including Aboriginal and other cultural groups, low-income women, teenage girls and heavy smokers. Another important group that merits increased attention is the ‘spontaneous quitter’. These are pregnant women who are former smokers, having quit either before entering prenatal care or in early pregnancy. Given the high rates of relapse observed postpartum, the programming for ‘pregnant smokers’ needs to be expanded to include these women and girls. The differing social and economic realities experienced by all of these groups lead to unique trajectories of tobacco cessation. However, in Canada, few smoking cessation programs are available that address the unique dynamics of cessation and relapse in these diverse subpopulations of pregnant smokers, and little material exists at all to assist postpartum women quit smoking. This article summarizes the types of programs currently available to Canadian pregnant smokers, and suggests directions for future program development. As part of a larger project investigating and suggesting better practices in this field, program materials and information (including evaluations) pertaining to pregnant smokers were sought from over 50 agencies in Canada and the US. A multitude of programs for women and for specific groups of women, such as Aboriginals, were obtained, but only nine programs were specifically designed for pregnant and/or postpartum women and/or girls (see Table I). Of these nine, four provided evaluation data. Table II lists additional resources aimed at healthcare providers.
