“…The most important finding in this study, unlike others conducted in Brazil 8,9 , was the role of ozone in low birth weight. Meanwhile, the study is consistent with Salam et al 12 , who point to a 40% increase in the odds of low birth weight.…”

The aim of this study was to assess the association between prenatal exposure to air pollutants and low birth weight in a medium-sized city. An ecological study was performed, using live birth data from São José dos Campos, São Paulo State, Brazil. The environmental data were obtained from the São Paul State Environmental Agency. The study included full-term newborns whose mothers were 20 to 34 years of age and had at least a complete high school education, seven or more prenatal visits, singleton pregnancy, and vaginal delivery, in order to minimize potential confounding from these variables. Logistic regression was used to estimate the effect of each pollutant. Low birth weight was defined as less than 2,500g. The sample included a total of 2,529 data from 2001 that met the inclusion criteria (25.6% of the total). We identified 99 newborns (3.95% of the sample) with low birth weight, and the pollutants sulfur dioxide and ozone were associated with low birth weight. The final model was À(x) = -1.79 + 1.30 (SO2) + 1.26 (O3). Thus, sulfur dioxide and ozone were identified as risk factors for low birth weight in a medium-sized city in Southeast Brazil.

“…Another potential limitation was the lack of information on maternal weight gain during the pregnancy, maternal height, public versus private prenatal care, and adequacy of nutrient intake. Such information is not included on certificates of live birth, and this gap has been identified in studies performed in Brazil 8,9 .…”

“…V). A significant association between risk of low birth weight and exposure to pollutants was found, like PM 10 , CO [98,112,118], SO 2 and O 3 [107]. A research [108] also revealed a gradient of approximately 50% of increasing risk of early neonatal death with higher exposure to traffic-related air pollution, compared with those less exposed.…”

“…Birth weight was analyzed as a dichotomous variable (normal birth weight or low birth weight) using univariate logistic regression models to assess the relationship between the following variables: maternal age (between 20 and 34 years of age, under 20 years of age, and over 34 years of age), years of maternal schooling (≤ 6 years and ≥ 7 years), number of prenatal visits (≤ 6 visits and ≥ 7 visits), delivery (normal or caesarean), kind of pregnancy (single or multiple), marital status (married or unmarried), and child's gender. The variable years of maternal schooling was used as a proxy for maternal smoking 8,10,13,17 .…”

“…Exposure to air pollution is also considered a risk factor for low birth weight and associations between air pollution and low birth weight have been observed in cities of different sizes 8,9,10,11,12 . A study conducted in Massachusetts (United States) between 1996 and 2002 found an association between exposure to traffic pollution and reduced birth weight, prematurity and social inequality 13 .…”
