      OBJECTIVES: To evaluate the effect of a provider counseling and office systems intervention in obstetric, pediatric, and Special Supplemental Nutrition Program for Women, Infants and Children (WIC) clinics on smoking and relapse rates in pregnant and postpartum women. METHODS: Five community health centers were randomized to special intervention (SI) or usual care (UC). Subjects (n =601) were current smokers or had quit with pregnancy. Prenatal and postpartum interviews assessed smoking status and related factors. Data were collected between May 1997 and November 2000. RESULTS: There was a statistically significant difference in 30-day abstinence rates between SI (26%) and UC (12%) conditions at the end of pregnancy among women who had not quit spontaneously with pregnancy (odds ratio [OR]=2.57, p =0.05). This effect remained at 1 month postpartum but was lost at 3- and 6-month postpartum follow-ups. CONCLUSIONS: Brief interventions delivered by healthcare providers during routine prenatal care increased smoking abstinence during pregnancy among women who did not quit spontaneously. Interventions extended into postpartum care did not affect relapse and smoking rates postdelivery.
    • Estudio Parto: postpartum diabetes prevention program for hispanic women with abnormal glucose tolerance in pregnancy: a randomised controlled trial - study protocol

      Chasan-Taber, Lisa; Marcus, Bess H.; Rosal, Milagros C.; Tucker, Katherine L.; Hartman, Sheri J.; Pekow, Penelope S.; Braun, Barry; Moore Simas, Tiffany A.; Solomon, Caren G.; Manson, Joann E.; et al. (2014-03-10)
      BACKGROUND: Diabetes and obesity have reached epidemic proportions in the U.S. with rates consistently higher among Hispanics as compared to non-Hispanic whites. Among Hispanic women diagnosed with gestational diabetes mellitus (GDM), 50% will go on to develop type 2 diabetes within 5 years of the index pregnancy. Although randomised controlled trials among adults with impaired glucose tolerance have shown that diet and physical activity reduce the risk of type 2 diabetes, such programs have not been tested in high-risk postpartum women. The overall goal of this randomised controlled trial is to test the efficacy of a culturally and linguistically modified, individually-tailored lifestyle intervention to reduce risk factors for type 2 diabetes and cardiovascular disease among postpartum Hispanic women with a history of abnormal glucose tolerance during pregnancy. METHODS/DESIGN: Hispanic pregnant women who screen positive for GDM will be recruited and randomly assigned to a Lifestyle Intervention (n = 150) or a Health and Wellness (control) Intervention (n = 150). Multimodal contacts (i.e., in-person, telephone, and mailed materials) will be used to deliver the intervention from late pregnancy (29 weeks gestation) to 12 months postpartum. Targets of the intervention are to achieve Institute of Medicine Guidelines for postpartum weight loss; American Congress of Obstetrician and Gynecologist guidelines for physical activity; and American Diabetes Association guidelines for diet. The intervention draws from Social Cognitive Theory and the Transtheoretical Model and addresses the specific cultural and environmental challenges faced by low-income Hispanic women. Assessments will be conducted at enrollment, and at 6-weeks, 6-months, and 12-months postpartum by trained bicultural and bilingual personnel blinded to the intervention arm. Efficacy will be assessed via postpartum weight loss and biomarkers of insulin resistance and cardiovascular risk. Changes in physical activity and diet will be measured via 7-day actigraph data and three unannounced 24-hour dietary recalls at each assessment time period. DISCUSSION: Hispanic women are the fastest growing minority group in the U.S. and have the highest rates of sedentary behavior and postpartum diabetes after a diagnosis of GDM. This randomised trial uses a high-reach, low-cost strategy that can readily be translated into clinical practice in underserved and minority populations. TRIAL REGISTRATION: NCT01679210.
    • Predictors of smoking cessation in pregnancy and maintenance postpartum in low-income women

      Ma, Yunsheng; Goins, Karin V.; Pbert, Lori; Ockene, Judith K. (2005-12-01)
      OBJECTIVE: To describe factors associated with smoking status of low-income women during pregnancy and postpartum. METHODS: Data from a randomized clinical trial were used to conduct separate analyses on 327 women who smoked at baseline (time at enrollment) and for whom smoking status was available at delivery, and on 109 women who reported not smoking at delivery (quit spontaneously or after study enrollment) and for whom smoking status was available at 6-months postpartum. Salivary cotinine was used to assess the accuracy of self-reported smoking status for the sample as a whole. Data were collected between May 1997 and November 2000. RESULTS: 18% of the 327 baseline smokers stopped smoking before delivery. Cessation was less likely in older women, those reporting Medicaid coverage (vs. commercial or no insurance), who were at a later week of pregnancy at baseline, were more addicted, had a husband/partner who smoked, and did not receive the study intervention. 37% of the 109 women who reported not smoking at delivery maintained abstinence at 6-months postpartum. Factors associated with abstinence were later week of pregnancy at baseline and quitting spontaneously with pregnancy, while women who lived with a smoker were less likely to report abstinence. Spontaneous quitters were less likely to relapse by 6 months postpartum than women who quit smoking later in pregnancy. CONCLUSIONS: Partner participation in smoking cessation programs for pregnant and postpartum women merits exploration. Lower relapse rates among spontaneous quitters indicate a need to foster an environment that encourages quitting at pregnancy.
