Multiple pregnancies and air pollution in moderately polluted cities: Is there an association between air pollution and fetal growth?
Background: Multiple pregnancies (where more than one fetus develops simultaneously in the womb) are systematically excluded from studies of the impact of air pollution on pregnancy outcomes. This study aims to analyze, in a population of multiple pregnancies, the relationship between fetal growth restriction (FGR), small for gestational age (SGA) and exposure to air pollution in moderately polluted cities. Methods: All women with multiple pregnancies living in the city of Besançon or in the urban area of Dijon and who delivered at a university hospital between 2005 and 2009 were included. FGR and SGA were obtained from medical records. Outdoor residential nitrogen dioxide (NO2) exposure wa…
Does low to moderate environmental exposure to noise and air pollution influence preterm delivery in medium-sized cities?
International audience; Background: Preterm birth (PB) is an important predictor of childhood morbidity and educational performance. Beyond the known risk factors, environmental factors, such as air pollution and noise, have been implicated in PB. In urban areas, these pollutants coexist. Very few studies have examined the effects of multi-exposure on the pregnancy duration. The objective of this study was to analyse the relationship between PB and environmental chronic multi-exposure to noise and air pollution in medium-sized cities.Methods: A case-control study was conducted among women living in the city of Besançon (121 671 inhabitants) or in the urban unit of Dijon (243 936 inhabitants…
Vulnerability during pregnancy in an urban environment : do environmental and individual risk factors cumulate?
International audience; Apart from demographic, socio-economic, behavioral, nutritional and medico-obstetrical factors, environmental factors have been suggested to be associated with adverse pregnancy outcomes, such as preterm birth, low birth weight or hypertensive disorders. According to a recent review of the literature, there is some suggestive evidence of adverse associations with environmental noise especially for low birth weight. However, the way these individual and environmental vulnerabilities combine has been scarcely studied. The objective of this study was to describe the accumulation of individual, socio-economics, medical and environmental vulnerability markers and to asses…
Exposition environnementale au bruit et à la pollution de l'air au cours de la grossesse avec comorbidités associées
L’objectif était d’analyser le lien entre l’exposition environnementale au bruit et à la pollution de l’air en milieu urbain et la prématurité chez les femmes dont le risque d’accouchement prématuré était augmenté par la présence d’une ou plusieurs comorbidités. Méthode. Une étude cas-témoins a été conduite sur les grossesses uniques accompagnées d’au moins une comorbidité. Les accouchements ont eu au CHU de Besançon ou de Dijon entre 2005 et 2009. Le niveau sonore de nuit (Lnight en façade du bâtiment d’habitation) et la concentration en dioxyde d’azote (NO2) dans les 50 m autour de l’habitation ont été modélisés à l’adresse déclarée au moment de l’accouchement. Une régression logistique c…
