BACKGROUND: The relationship between arsenic and birth weight is not well understood.
OBJECTIVE: To evaluate the causal relationship between prenatal arsenic exposure and birth weight considering the potential mediation effects of gestational age (GA) and maternal weight gain (MWG) during pregnancy using structural equation models (SEMs).
METHODS: A prospectively enrolled...
Mercury and arsenic are known developmental toxicants and environmental exposures are ubiquitous worldwide from natural and anthropogenic sources. Prenatal exposure to both contaminants are independently associated with adverse perinatal health outcomes and latent disease risk that could be in part mediated by epigenetic reprogramming events. Fetal programming events involving DNA...
BACKGROUND: Arsenic, a common groundwater pollutant, is associated with adverse reproductive health but few
studies have examined its effect on maternal health.
METHODS: A prospective cohort was recruited in Bangladesh from 2008–2011 (N = 1,458). At enrollment (<16 weeks
gestational age [WGA]), arsenic was measured in personal drinking water using...
