ABSTRACT
The prevalence of smoking during pregnancy in Ribeirão Preto, a rich Brazilian city, was significantly higher (21.4 percent) than in São Luís (5.9 percent), a less developed city. To assess which variables explain the difference in prevalence of smoking during pregnancy, data from two birth cohorts were used, including 2846 puerperae from Ribeirão Preto, in 1994, and 2443 puerperae from São Luís, in 1997/98. In multivariable analysis, risk of maternal smoking during pregnancy was higher in São Luís for mothers living in a household with five or more persons (OR = 1.72, 95 percentCI = 1.12-2.64), aged 35 years or older (OR = 1.98, 95 percentCI = 0.99-3.96), who had five or more children (OR = 2.10, 95 percentCI = 1.16-3.81), and whose companion smoked (OR = 2.20, 95 percentCI = 1.52-3.18). Age of less than 20 years was a protective factor (OR = 0.55, 95 percentCI = 0.33-0.92). In Ribeirão Preto there was association with maternal low educational level (OR = 2.18, 95 percentCI = 1.30-3.65) and with a smoking companion (OR = 3.25, 95 percentCI = 2.52-4.18). Receiving prenatal care was a protective factor (OR = 0.24, 95 percentCI = 0.11-0.49). Mothers from Ribeirão Preto who worked outside the home were at a higher risk and those aged 35 years or older or who attended five or more prenatal care visits were at lower risk of smoking during pregnancy as compared to mothers from São Luís. Smoking by the companion reduced the difference between smoking rates in the two cities by 10 percent. The socioeconomic variables in the model did not explain the higher prevalence of smoking during pregnancy in the more developed city.
