[BDSP. Notice produite par INIST-CNRS qUjR0x46. Diffusion soumise à autorisation]. Objectives. This study examined the patterns and correlates of maternal smoking before. during, and after pregnancy. Methods. We examined socioeconomic, demographic, and clinical risk factors associated with maternal smoking in a nationally representative cohort of women (n=8285) who were surveyed 17 ñ 5 months and again 35 ñ 5 months after delivery. Results. Smoking rates among women with a college degree decreased 30% from be fore pregnancy to 35 months postpartum but did not change among the least educated women. Risk factors clustered, and a gradient linked the number of risk factors (0,2. 4) to the percentage smoking (6%, 31%, 58%, P<. 0001). Conclusions. The period of pregnancy and early parenthood is associated with worsening education-related disparities in smoking as well as substantial clustering of risk factors. These observations could influence the targeting and design of maternal smoking interventions.
