“…In addition, Li et al found that exposure to NO 2 in the third trimester significantly increased birth weight, while O 3 exposure decreased it, which was consistent with our conclusion (Li et al 2019). However, contrary to our findings, most previous related studies still suggested that prenatal exposure to PM 2.5 , PM 10 , and CO in the third trimester might cause birth weight reduction significantly (Chen et al 2018;Guo et al 2017;He et al 2018;Santos Vde et al 2016;Ye et al 2018). Several reasons, such as the concentration difference and misclassification of air pollution, and co-linearity questions might explain the inconsistent results among these studies.…”

Previous studies have suggested that maternal exposure to air pollution might affect term birth weight. However, the conclusions are controversial. Birth data of all term newborns born in Xi’an city of Shaanxi, China, from 2015 to 2018 and whose mother lived in Xi’an during pregnancy were selected form the Birth Registry Database. And the daily air quality data of Xi’an city was collected from Chinese Air Quality Online Monitoring and Analysis Platform. Generalized additive models (GAM) and 2-level binary logistic regression models were used to estimate the effects of air pollution exposure on term birth weight, the risk term low birth weight (TLBW), and macrosomia. Finally, 321521 term newborns were selected, including 4369(1.36%) TLBW infants and 24,960 (7.76%) macrosomia. The average pollution levels of PM2.5, PM10, and NO2 in Xi’an city from 2015 to 2018 were higher than national limits. During the whole pregnancy, maternal exposure to PM2.5, PM10, SO2, and CO all significantly reduced the term birth weight and increased the risk of TLBW. However, NO2 and O3 exposure have significantly increased the term birth weight, and O3 even increased the risk of macrosomia significantly. Those effects were also observed in the first and second trimesters of pregnancy. But during the third trimester, high level of air quality index (AQI) and maternal exposure to PM2.5, PM10, SO2, NO2, and CO increased the term birth weight and the risk of macrosomia, while O3 exposure was contrary to this effect. The findings suggested that prenatal exposure to air pollution might cause adverse impacts on term birth weight, and the effects varied with trimesters and pollutants, which provides further pieces of evidence for the adverse effects of air pollution exposure in heavy polluted-area on term birth weight.

“…16,17 As mães que relataram uso de tabaco durante a gestação, mães adolescentes e famílias com maior aglomeração no domicílio, apresentaram média de peso ao nascer inferior às categorias de referência. Os demais fatores avaliados não afetaram de maneira significante o peso médio ao nascer das crianças que participaram deste estudo.…”

Objetivo: Identificar os fatores sociais e gestacionais associados ao peso ao nascer de crianças nascidas a termo. Métodos: Trata-se de estudo transversal realizado entre setembro de 2004 e julho de 2005. As informações foram obtidas por meio da Declaração de Nascidos Vivos e de visita domiciliar subsequente ao nascimento da criança. Resultados: O peso médio ao nascer na amostra estudada foi de 3,146 (±375 g), sendo que a incidência de nascidos vivos com baixo peso ao nascer foi de 7,5%. Observou-se, na análise multivariada, que crianças do gênero feminino, idade materna inferior a 19 anos, o hábito de fumar durante a gestação e maior aglomeração de pessoas no domicílio associaramse significantemente com menor média de peso ao nascer. A diferença mais expressiva ocorreu entre as crianças cujas mães eram tabagistas, com uma média de peso dessas crianças menor que 258grs quando comparadas com mães não tabagistas (p=0,001). De forma conjunta, esses fatores responderam por 16% da variação do peso ao nascer. Conclusão: Considera-se necessário maior investimento na atenção básica, na tentativa de reduzir o número de gestantes adolescentes e do hábito de fumar durante a gestação, dentre outros fatores relevantes para a saúde do recém-nascido

“…A partir daí, calculou-se a média dos poluentes no período de 9 meses que antecederam os nascimentos, ou seja, no período entre março e novembro. Dessa forma, obteve-se os dados aproximados da concentração dos poluentes para o 1º, 2º e 3º trimestres (SANTOS et al, 2016).…”

This study aims to identify the association between air pollution and perinatal outcomes in the municipality of Santos, as well as to identify risk areas in the city for such an outcome from January 2012 to December 2015. The design is mixed, with parts of a retrospective cohort, as it works with secondary data, and ecological study, as it works with spatial data. Logistic regression analysis was performed with 10,319 live births. Live birth data were obtained through the Information System on Live Births (SINASC). Daily records of air pollutants (PM10, PM2.5, NO2 and O3), temperature and relative humidity were obtained through the São Paulo State Environmental Agency (CETESB). Spatial scan analysis was performed to identify areas of risk for prematurity and then, compared with census sectors according to the Paulista Index of Social Vulnerability (IPVS). Analysis were also performed to calculate the Moran Index to identify spatial correlation of cases between neighborhoods. The variables prenatal visits, mother's age and number of children born deceased showed a significant positive association with the outcome of LBW and prematurity. For Low birth weight: when pollutants were considered continuously, PM2.5 and PM10 and NO2 showed a protective effect in the third trimester, but with no association in the first and second, while O3 showed no association in any of the trimesters. For PM2.5, no significant association was found for the first and third trimester. Only the second quartile of the second trimester (OR = 1.41, 95% CI: 1.12 -1.76) showed a positive association with statistical significance. Only the last quartile of the third trimester (OR = 1.27 95% CI 1.23 -1.57) showed a positive association with significance. A significant association was found for the second and third quartiles in the second and third trimesters for PM10. For prematurity: no association was found between NO2 and PM2.5 and prematurity. O3 showed a significant association in the first trimester, in the last quartile (OR = 1.47 CI 95% 1.05; 2.07). PM10 showed a significant association in the first trimester, in the last quartile (OR = 1.28 CI 95% 1.00; 1.64) and in the second trimester, in the second quartile (OR = 1.37 CI 95% 1.07; 1, 77). Risk areas for prematurity and LBW had more census sectors with medium and high vulnerability. Areas with low risk for LBW and prematurity had census sectors with very low vulnerability. Results show evidence that maternal exposure to pollutants can contribute to prematurity and LBW, as well as suggest that having homes in a region of high vulnerability can also contribute to these outcomes.

Poluentes atmosféricos associados ao peso insuficiente ao nascimento

Abstract: The survey results indicate that maternal exposure to air pollution in the 1st and 3rd trimesters of pregnancy for residents of São José dos Campos create considerable potential to cause insufficient weight.
