Intrauterine inflammation and maternal exposure to ambient PM2.5 during preconception and specific periods of pregnancy: The Boston Birth Cohort

Prenatal exposure to ambient PM2.5, (i.e., fine particulate matter) has been associated with preterm birth and low birth weight. The association between prenatal PM2.5 exposure and intrauterine inflammation (IUI), an important risk factor for preterm birth and neurodevelopmental outcomes, has not been evaluated. The researchers aimed to investigate the association between maternal exposure to PM2.5 and IUI in the Boston Birth Cohort (BBC), a predominantly urban low-income minority population.
