RESUMO
Introduction: The atmospheric pollution is a public health problem worldwide. The adverse effects related to air pollutants are robustly associated with respiratory and cardiovascular diseases and, in a lesser extent, with pregnancy adverse outcomes. Objective: estimating the relationship between air pollutants PM10 and O3 and low birth weight of children were borne in the city of Santo André, São Paulo. Casuistic and methods: This is a crossectional study. We included in the study all newborns of mothers that were inhabitants of Santo André, São Paulo, Brazil, and that were born from 2000 to 2006. The São Paulo State Environmental Agency (CETESB) provided daily records of particulate matter (PM10), temperature, and humidity. We performed descriptive analysis and logistic regressions. Results: Among the 58,114 newborns it was observed a low birth weight rate of 5.9%. There was a dose-response relationship between PM10 concentrations and low birth weight. Particles concentrations in the highest quartile in the third trimester of pregnancy increased the risk of low birth weight in 32% ((Odds Ratio: 1,32; 95% CI: 1,15 1,50) when compared with the first quartile. The same pattern of effect was observed in the other trimesters. For the O3 not were detected risks. Conclusion: The increase in PM10 concentrations, in Santo André, during the studied period, lead to an increase in the odds of low birth weight. This effect was observed even though there was no surpassing of air quality standards
