“…Overreporting of smoking cessation by pregnant women is mentioned in the literature 34,35 and could partly account for the better smoking outcomes we found for women in prenatal services. However, overreporting has occurred in studies in which assessments were conducted by clinic personnel during clinic visits.…”

Objectives. This study assessed the prevalence and effectiveness of smoking cessation interventions for women of childbearing age in public health clinics.Methods. Smokers in prenatal, family planning, and well-child services in 10 public health clinics (n = 1021) were interviewed 5 to 8 weeks after a medical visit to assess their exposure to smoking cessation interventions and smoking cessation outcomes.Results. Depending on clinic service and intervention component (poster, video segment, provider advice, booklet), 16% to 63% of women reported exposure to an intervention component during their visit. Women in prenatal services received more interventions and had better outcomes than those in the other services.Conclusions. Exposure to more interventions increased readiness and motivation to quit and the number of actions taken toward quitting. (Am J

“…Outros estudos sugerem que o declínio da prevalên-cia do fumo nas grávidas se deve ao aumento da cessação durante a gestação. 1,3 Entretanto, deve-se considerar também a possibilidade da subestimação do consumo de cigarros revelada em alguns estudos, 5,8 onde as gestantes, possivelmente intimidadas pela cobrança social, ocultam o real consumo.…”

OBJETIVO: Avaliar a correlação dos fatores sociodemográficos e estilo de vida com o hábito de fumar em gestantes atendidas em hospitais. MÉTODOS: O delineamento foi o de um estudo transversal. A amostra foi composta por 5.539 gestantes atendidas em ambulatórios de pré-natal em hospitais públicos credenciados nas cidades de Manaus, Fortaleza, Salvador, Rio de Janeiro, São Paulo e Porto Alegre, entre 1991 e 1995. A seleção foi consecutiva para todas as gestantes com 20 anos ou mais de idade, excetuando-se aquelas com diabetes prévia à gestação. Foram realizadas medidas antropométricas e entrevistas entre a 21ª e a 28ª semanas da gravidez. Por meio de um questionário padronizado, considerou-se como fumante quem informou fumar um ou mais cigarros por dia, como ex-fumante quem informou ter fumado mais de um cigarro por dia e ter cessado, e não fumantes quem informou nunca ter fumado um ou mais cigarros por dia. RESULTADOS: O hábito de fumar na gestação associou-se à baixa escolaridade (RC=2,13; IC 95%: 1,76-2,57) e paridade (RC=1,84; IC 95%: 1,53-2,21). Para o aumento da idade da gestante e uso de bebidas alcóolicas também foram observadas associações positivas com o fumo na gestação. Não foi observada nenhuma associação significativa entre cor da pele e situação ocupacional com fumo na gestação. Um efeito protetor foi observado para mulheres casadas ou com companheiro (RC=0,55; IC 95%: 0,42-0,72). Entre as cidades, tomando Manaus como referência, Porto Alegre apresentou o maior risco para fumo na gestação (RC=5,00; IC 95%: 3,35-7,38), seguida de São Paulo (RC=3,42; IC 95%: 2,25-5,20), Rio de Janeiro (RC=2,53; IC 95%: 1,65-3,88) e Fortaleza (RC=2,56; IC95%: 1,74-3,78). CONCLUSÕES: Os achados são semelhantes àqueles descritos na literatura com relação à escolaridade, paridade e situação conjugal. Entretanto, nenhuma associação com a cor da pele foi observada na análise multivariada. As ex-fumantes mostraram características sociodemográficas mais próximas das não fumantes do que das fumantes.

“…The information was obtained from public and private services. There is the possibility of an underestimate of smoking rates (information bias) as a function of the reluctance of pregnant women, intimidated by social demands, to openly recognize this habit or to declare their real cigarette consumption, situations that have been reported in the literature (24,25). Although biological indicators such as urinary nicotine levels were not investigated for comparison with the replies of the puerperae to the questionnaire, a high level of correspondence (sensitivity, specificity and predictive values) has been demonstrated between replies to questionnaires and urinary nicotine levels in studies on smoking during pregnancy (26), supporting once again the importance of the epidemiological studies presented here.…”

The prevalence of smoking during pregnancy in Ribeirão Preto, a rich Brazilian city, was significantly higher (21.4%) than in São Luís (5.9%), 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%CI = 1.12-2.64), aged 35 years or older (OR = 1.98, 95%CI = 0.99-3.96), who had five or more children (OR = 2.10, 95%CI = 1.16-3.81), and whose companion smoked (OR = 2.20, 95%CI = 1.52-3.18). Age of less than 20 years was a protective factor (OR = 0.55, 95%CI = 0.33-0.92). In Ribeirão Preto there was association with maternal low educational level (OR = 2.18, 95%CI = 1.30-3.65) and with a smoking companion (OR = 3.25, 95%CI = 2.52-4.18). Receiving prenatal care was a protective factor (OR = 0.24, 95%CI = 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%. The socioeconomic variables in the model did not explain the higher prevalence of smoking during pregnancy in the more developed city.
