Abstract A cross-sectional study was carried out to estimate the prevalence of miscarriages in a population of 360 women distributed in areas exposer to higher and lower vehicle traffic air pollution on the Island of São Luís, MA, Brazil, and identify associated variables. Participants were interviewed and bivariate and multivariate logistic regressions were conducted. The overall miscarriage prevalence was of 15.83%, totaling 25.56% (n=180) in the higher exposure area and 6.11% (n=180) in the lower exposure area. Maternal alcohol consumption (OR=3.11), STIs during pregnancy (OR=2.74), living in a high-exposure area (OR=8.32), having suffered physical or psychological distress during pregnancy (OR=4.25) and repeated miscarriages (OR=39.11) were all associated to the miscarriage outcome. The findings reported herein thus indicate potential vehicle traffic air pollution contribution as a risk factor in the etiology of miscarriages.

Resumo Realizou-se um estudo transversal para estimar a prevalência de abortamento espontâneo em 360 mulheres distribuídas em área de maior e menor exposição à poluição atmosférica proveniente do tráfego de veículos na Ilha de São Luís-MA e identificação de variáveis associadas. As participantes foram entrevistadas e os dados coletados foram submetidos à regressão logística bivariada e multivariada. A prevalência geral de aborto espontâneo foi 15,83%, correspondendo a 25,56% (n=180) na área de maior exposição e 6,11% (n=180) na área de menor exposição. Associaram-se ao aborto espontâneo o etilismo materno (OR=3,11), a presença de IST na gestação (OR=2,74), viver na área de alta exposição (OR=8,32), ter sofrido violência física ou psicológica na gestação (OR=4,25) e a ocorrência de abortamento de repetição (OR=39,11). Os resultados apontam para uma possível contribuição da poluição do ar proveniente do tráfego de veículos como fator de risco na etiologia do aborto espontâneo.

Abstract: Recent statements from the Brazilian federal government indicate that impacting economic activities, particularly commercial shrimp farming, are being encouraged in mangrove areas in the near future. Alterations of the National Action Plan and legal instruments that partially protected mangrove ecosystems have created an even weaker legal framework than previously existed. Such changes are leading Brazil far from the global call to conserve mangroves and from the Aichi targets and United Nations Sustainable Development Goals. Unfortunately, the loss of mangrove ecosystems and their ecosystem services will negatively impact living standards for Brazilians in coastal areas.
