Introduction: Smoking remains the single-most significant preventable cause of poor pregnancyoutcomes, yet around 12% of Australian women smoke during pregnancy. Many women are motivatedto quit when they find out they are pregnant, yet few are successful. While previous studieshave examined the profile of the maternal smoker compared to her nonsmoking counterpart (Aim1), little is known about what differentiates women who quit during pregnancy to those who donot (Aim 2). Here, we present results from a study investigating the characteristics of women whowere able to quit during pregnancy.Methods: Data were drawn from the Tasmanian Population Health database of women who hadreceived antenatal care between 2011 and 2013 (n  =  14300). Data collected included age, relationshipstatus and ethnicity of expectant mothers, antenatal details, mental health conditions,and drug use. Independent samples t tests were used to compare differences between womenwho had, and those who had not, quit during pregnancy. The 19.4% of women who self-reportedas smoking in the first half (first 20 weeks) of their pregnancy were further grouped and analyzedcomparing those who reported still smoking in the second half of their pregnancy (smokers:n = 2570, 92.4%) to those who quit (quitters: n = 211, 7.6%).Results: Quitters (57.8%) were more likely to be in a relationship than their non-quitting counterparts(49.6%, p = .022) and were less likely to suffer from postnatal depression (2.4% vs. 6.0%,p = .029). No other differences between quitters and smokers were observed.Conclusions: Determining the profile of women who are able to quit during pregnancy may beimportant to improve the relatively poor cessation rates among maternal smokers and may assistin more effectively targeting at-risk women.Implications: Smoking cessation interventions have traditionally targeted socially disadvantagedwomen, for good reason: the majority of smoking pregnant women fall into this category.However, despite the significant attention and resources dedicated to antenatal smoking cessationinterventions, most are ineffective with only 7.6% of the present sample quitting smoking duringpregnancy. This paper may assist in developing more effective antenatal smoking cessation interventionsby more clearly describing the profile of maternal smokers who successfully quit duringpregnancy. Specifically, this paper highlights the need to acknowledge and address women’s relationshipstatus and mental health in order to promote smoking cessation in pregnancy.
