Resumo: | OBJECTIVE: Air pollution has been investigated as a potential determinant for low birthweight. The aim of the present study was to study the effect of air pollution on birthweight. METHODS: We analyzed all deliveries by mothers living in the municipality of Sao Paulo, Southeastern Brazil, between 1998 and 2000. We estimated the prevalence of low birthweight according to newborn, mother, and delivery characteristics. Only births occurring in the most central districts of the city were analyzed, totaling 311.735 events. For the evaluation of the effects of air pollution, we excluded preterm and multiple deliveries. Pollutants analyzed were ozone (O3), sulfur dioxide (SO2), nitrogen dioxide (NO2), suspended particles (PM10), and carbon monoxide (CO). The effect of maternal exposure to air pollution on birthweight was evaluated using linear and logistic regression. RESULTS: A total of 4.6% of newborns weighed less than 2,500 g at birth. Maternal exposure to CO, PM10, and NO2 during the first trimester of pregnancy was significantly associated with decreased birthweight. CONCLUSIONS: Our results reinforce the notion that maternal exposure to air pollution during the first trimester of pregnancy may contribute to lesser weight gain in the fetus. |

OBJETIVO: A poluição do ar tem sido investigada como possível determinante do baixo peso ao nascer. O objetivo do estudo foi verificar o efeito da poluição do ar sobre o peso ao nascer. MÉTODOS: Foram analisados todos os partos de mães residentes no Município de São Paulo, nos anos de 1998 a 2000. Estimaram-se as prevalências de baixo peso ao nascer conforme características do recém-nascido, da mãe e do parto. Apenas os distritos mais centrais de São Paulo foram incluídos, totalizando uma amostra de 311.735 nascimentos. Para avaliação do efeito da poluição do ar foram excluídos os prematuros, gemelares e analisados somente os nascimentos das áreas mais centrais da cidade. Os elementos poluentes analisados foram ozônio (O3), dióxido de enxofre (SO2), dióxido de nitrogênio (NO2), partículas em suspensão (PM10) e monóxido de carbono (CO). O efeito da exposição materna à poluição do ar no peso ao nascer foi avaliado por meio de regressão linear e logística. RESULTADOS: Do total analisado, 4,6% dos recém-nascidos apresentaram menos de 2.500 g ao nascer. A exposição materna ao CO, PM10 e NO2 durante o primeiro trimestre de gestação mostrou associação estatisticamente significante com a diminuição no peso do recém-nascido. CONCLUSÕES: Os resultados reforçam que a exposição materna à poluição do ar no primeiro trimestre de gestação pode contribuir para o menor ganho de peso do feto. Universidade de São Paulo.
