Abstract
ABSTRACTOBJECTIVETo measure the prevalence of smoking cessation during pregnancy and to identify factors associated with its occurrence.METHODSThe present survey included all puerperal women living in the municipality of Rio Grande, RS, whose birth occurred between January 1 and December 31, 2013. A single standardized questionnaire was applied, in the hospital, within 48 hours of delivery. Multivariate analysis was performed using Poisson regression with robust variance.RESULTSThe prevalence of smoking cessation among the 598 parturients studied was 24.9% (95%CI 21.5-28.6). After adjusting for confounding factors, mothers aged 13 to 19 years (PR = 1.76; 95%CI 1.13-2.74), who had higher family income (PR = 1.83; 95%CI, 1.23-2.72), higher educational level (PR = 2.79; 95%CI 1.27-6.15), higher number of prenatal appointments (PR = 1.84; 95%CI 1.11-3.05), and who did not smoke in the previous pregnancy (PR = 2.93; 95% CI, 1.95-4.41) presented a higher prevalence ratio of smoking cessation.CONCLUSIONSAlthough pregnancy is a window of opportunity for smoking cessation, the rate of cessation was low. The prevalence of cessation was higher among mothers with lower risk of complications, suggesting the need for interventions prioritizing pregnant women of lower socioeconomic levels.

Summary
Smoking during pregnancy is the main preventable risk factor for several unfavorable outcomes, both for the baby and the pregnant woman. Reducing the occurrence of smoking during pregnancy is a public health priority. Considering all the moments in which smoking can be discouraged, the gestational period is possibly the one with greatest potential impact. Above all else, the well-being of her child, she will be much more willing to make a more forceful effort than in other situations where smoking is normally discouraged. Reducing the intensity of exposure to smoke brings benefits to both mother and newborn, and the earlier this occurs, the lower the adverse effects[2,3]
