“…Vigorous physical activity was virtually absent in the present study, confi rming a previous cohort survey 21 including 153 low-income pregnant women attending public prenatal care facilities in the city of Sao Paulo. We were therefore unable to compare our data with those studies that detected associations between moderate to vigorous physical exercise/exertion and maternal-fetal health.…”

“…Other studies that analyzed (intentional or not) walking found a similar protective effect against inadequate birth weight (OR=0.44; 95% CI:0.20; 0.98) 21 or In regard to the hypothesis of a U-shaped relationship between physical activity and pregnancy outcomes, our results provide evidence for the extreme left side of this curve -increased risk of low birth weight and preterm birth among less active women who spend less time on general mild activities, housework, and leisure walks. The other extreme of the curve could not be tested as vigorous physical activity was rare among our subjects.…”

OBJECTIVE:To investigate the relationship between physical activity during the second trimester pregnancy and low birth weight, preterm birth, and intrauterine growth restriction. METHODS:Case-control study including 273 low birth weight newborns and 546 controls carried out in the city of São Paulo, Southeastern Brazil, in 2005. Low birth weight cases were grouped into two subsamples: preterm birth (n=117) and intrauterine growth restriction (n=134), with their related controls. Information was collected by means of interviews with mothers shortly after birth and transcription of medical records. Data were analyzed using conditional multiple and hierarchical logistic regression. RESULTS:Light physical activity for over 7 hours per day was shown to be protective against low birth weight (adjusted OR=0.61; 95% CI 0.39-0.94) with a dose-response relationship (p-value for trend=0.026). A similar trend was found for intrauterine growth restriction (adjusted OR=0.51; 95% CI 0.26-0.97). Homemaking activities were associated as a protective factor for both low birth weight and preterm birth (p-value for trend=0.013 and 0.035, respectively). Leisure-time walking was found to be protective against preterm birth. CONCLUSIONS:Mild physical activity during the second trimester of pregnancy such as walking has an independent protective effect on low birth weight, preterm birth, and intrauterine growth restriction. Low birth weight is an important public health issue in both developed and developing countries. It is the main factor infl uencing health and nutritional conditions and child survival, and is also associated with occurrence of chronic diseases in adult life. 10Over the past two decades -in contrast to the declining trend seen for many health indicators, such as child mortality, postnatal malnutrition, and malnutrition among adult women -prevalence of low birth weight (under 2,500 grams) has remained stable, or even increased in cities of Southern and Southeastern Brazil. There are two major processes that can lead to low birth weight: preterm birth and restricted intrauterine growth. In the city of Pelotas, over the last two decades, Barros et al 2 observed a slight increase in the prevalence of low birth weight and a greater increase in preterm birth (6.3% in 1982 to 16.2% in 2004), whereas prevalence of intrauterine growth restriction (IUGR) remained unaltered. RESUMO OBJETIVO:Analisar a relação entre atividade física durante o segundo trimestre de gestação e baixo peso ao nascer, prematuridade e restrição de crescimento intra-uterino. MÉTODOS:Estudo de caso-controle realizado no município de São Paulo, em 2005. Foram estudados 273 recém-nascidos de baixo peso e 546 controles. Dentre os casos foram selecionadas duas sub-amostras: 117 nascimentos pré-termo e 132 com restrição de crescimento intra-uterino (n=132) e seus respectivos controles. As informações foram obtidas mediante entrevistas com as puérperas e transcrição de dados dos prontuários. Foram realizadas análises de regressão logística múltipla...

Determinants of weight gain in pregnant women attending a public prenatal care facility in Rio de Janeiro, Brazil: a prospective study, 2005-2007

The objective of this study was to evaluate the determinants of weight gain during pregnancy. The study adopted a prospective cohort design with four follow-up waves and included a sample of 255 pregnant women that received prenatal care at a public health care facility in Rio de Janeiro, Brazil. A mixed-effects linear longitudinal regression model was used, having as the dependent variable the weight assessed in four follow-up waves, and as independent variables: demographic, socioeconomic, reproductive, behavioral, and nutritional data. Mean weight gain was 0.413kg per gestational week, consistent with recommendations by the Institute of Medicine. Per capita family income and smoking were associated with total weight gain during gestation. According to the longitudinal multiple linear regression model, age (² = 0.6315), menarche (² = -2.3861), triglycerides (² = 0.0437), blood glucose (² = 0.1544), and adequacy of energy consumption (² = -0.0642) were associated with gestational weight gain. Special attention should be given to these sub-groups, due to increased risk of excessive weight gain.

“…Essa metodologia reduz a possibilidade de proposições e recomendações específicas para atividade física. Em estudo anterior no qual atividades em pé puderam ser detalhadas, identificou-se associação específica da atividade de lavar roupa com o peso inadequado ao nascer (31) . As análises do presente estudo parecem assegurar a reprodutibilidade do questionário de atividade física para gestantes usuárias de serviços públicos de saúde com características semelhantes a amostra estudada.…”

Introdução: A prática de atividade física tem sido incentivada por vários organismos nacionais e internacionais visando a promoção de saúde. Entretanto não existe consenso acerca da influência e da intensidade ótima de atividade física durante a gestação, possivelmente devido a dificuldades de mensuração e classificação do nível de atividade física através de questionários. Não se identificou qualquer estudo de validação de questionário de atividade física em gestantes no Brasil. O objetivo do presente estudo é analisar a reprodutibilidade e validade concorrente de um questionário de atividades físicas para gestantes. Métodos: Em amostra de 68 gestantes, no segundo trimestre de gestação foi realizada entrevista para aplicação do questionário, que foi repetida com aproximadamente uma semana de intervalo e no puerpério. No período entre as duas primeiras entrevistas, as mulheres utilizaram monitor de freqüência cardíaca (n=38). Resultados: As análises de reprodutibilidade foram adequadas com coeficientes de correlação intraclasse variando de 0,54 a 0,85. A análise das variáveis categóricas, com questões subjetivas e de autopercepção da atividade física, resultou em maior intervalo de coeficiente kappa com valores entre 0,29 e 0,76 entre a aplicação do questionário com uma semana de intervalo, e 0,08 a 0,70 comparado ao puerpério. As análises de validade conduziram a resultado satisfatório quanto à média das diferenças encontrada por intermédio do gráfico de Bland e Altman (1986) entre o questionário e o freqüencímetro. Entretanto, o intervalo da dispersão não se apresentou adequado, visto que variou em mais de sete horas para atividades leves e em quase onze horas por dia para atividades moderadas. As análises do presente estudo parecem assegurar a reprodutibilidade do questionário de atividade física para gestantes. No entanto, com relação à validação, a comparação com os resultados obtidos pelo freqüêncímetro não mostrou graus de concordância adequados.Palavras-chave: atividade cotidiana, confiabilidade, questionário, gravidez, cuidado pré-natal. ABSTRACTIntroduction: Physical activity practice has been encouraged by several national and international entities aiming health promotion. However, there is no consensus concerning the influence and optimal intensity of physical activity during pregnancy, probably due to difficulties to measure and classify the level of physical activity by questionnaires. It has not been identified any validation study of physical activity questionnaire on Brazilian pregnant women. The purpose of the present study is to analyze the reliability and concurrent validity of a physical activity questionnaire for pregnant women. Methods: A sample of 68 women in the second trimester of pregnancy has been interviewed by the elaborated questionnaire. Reliability was assessed after approximately a week and in the postpartum. The subjects used a heart rate monitor between the two first interviews (n=38). Results: Reproducibility analyses were adapted with interclass correlation coefficients var...
