Predictors of smoking cessation during pregnancy.
OBJECTIVE
The purpose of this study was to determine predictors of smoking cessation from a sample of pregnant Medicaid recipients. Of special interest was whether patient stage of change, based on the transtheoretical model, was predictive of smoking behavior change during pregnancy.


METHODS
The sample was drawn from a cohort of pregnant smokers who were participants in a prospective, randomized clinical trial conducted in four public health maternity clinics in Birmingham, Alabama, USA.


METHODS
The 435 participants entered prenatal care on or before their 24th week of gestation and had saliva collected for cotinine assays at baseline and follow-up. In this secondary analysis, descriptive statistics defined the sample, cross-tabulation procedures identified a preliminary set of predictor variables, and discriminant function analyses predicted group membership--quitter or smoker.


CONCLUSIONS
Discriminant function analyses revealed that patient baseline cotinine value, duration of smoking habit, self-efficacy, exposure to environmental tobacco smoke, and exposure to patient education methods were predictive of non-smoking status assessed during the third trimester of pregnancy.
