ABSTRACT

Purpose:

The aim of the present study was to evaluate the prevalence of active and passive smoking during pregnancy and its association with sociodemographic indicators, as well as perinatal and postnatal outcomes in newborns.

Methods:

This cross-sectional study was comprised of 431 pairs of mothers/ newborns. The study variables were preterm birth, birth weight, oral mucosal lesions, sociodemographic indicators and smoking data. We collected data from medical records and through a self-administered questionnaire answered by mothers. A pediatric dentist examined the newborns for oral mucosal lesions. Bivariate and multivariate logistic regression models were used to evaluate the association between active and passive smoking and the other variables (α=5%).

Results:

The prevalence of active (9.5%) and passive smoking (4.2%) during pregnancy was low. Active smoking was statistically associated with low birth weight (OR 2.4; 95%CI1.1-5.3), lower schooling level (OR 0.2; 95%CI0.1-0.5) and mothers aged ≥36 years old (OR 4.9; 95%CI1.2-20.0). Passive smoking was not statistically associated with the other variables. There was no association between active or passive smoking during pregnancy and premature birth and oral lesions of the newborn.

Conclusions:

The prevalence of active and passive smoking were low. Active smoking was associated with low birth weight, maternal age and mother's schooling, suggesting a social influence of smoking behavior among a population with a lower educational level. There was no association between active and passive smoking and prematurity and oral lesions of the newborn. (AU)
RESUMO

Objetivo:

O objetivo do estudo foi avaliar a prevalência de tabagismo ativo e passivo durante a gestação e a associação entre indicadores sociodemográficos, bem como desfechos pré e pós-parto em recém-nascidos.

Metodologia:

Este estudo transversal foi composto por 431 pares de mães/recém-nascidos. As variáveis estudadas foram nascimento prematuro, peso ao nascer, lesões mucosas orais, indicadores sociodemográficos e dados sobre tabagismo. Coletamos dados por meio de prontuários e por questionário auto-aplicado respondido pelas mães. Um dentista pediátrico examinou os recém-nascidos para lesões mucosas orais. A regressão logística foi utilizada para a análise bivariada e multivariada dos dados (α=5%).

Resultados:

Prevalência de tabagismo ativo (9,5%) e tabagismo passivo (4,2%) durante a gravidez foi baixo. O tabagismo ativo foi estatisticamente associado ao baixo peso ao nascer (OR 2,4; 95%CI1,1-5,3), às mães com menor escolaridade (OR 0,2; 95%CI0,1-0,5), e mães com idade ≥36 anos (OR 4,9; 95%CI1,2-20,0); enquanto o tabagismo passivo não esteve estatisticamente associado a nenhuma variável. Não houve associação entre tabagismo durante a gestação com nascimento prematuro e lesões orais de recém-nascidos.

Conclusões:

As prevalências de tabagismos passivo e ativo foram baixas. O tabagismo ativo esteve associado ao baixo peso ao nascer, à idade materna e à escolaridade da mãe, sugerindo influência social do comportamento do tabagismo entre a população com menor escolaridade. Não houve associação entre tabagismo ativo e passivo com prematuridade e lesões de mucosa oral em recém-nascido. (AU)
