Trimester effects of source-specific PM₁₀ on birth weight outcomes in the Avon Longitudinal Study of Parents and Children (ALSPAC).

ABSTRACT:

Background

Evidence suggests that exposure to particulate matter with aerodynamic diameter less than 10 μm (PM₁₀) is associated with reduced birth weight, but information is limited on the sources of PM₁₀ and exposure misclassification from assigning exposures to place of residence at birth.

Methods

Trimester and source-specific PM₁₀ exposures (PM₁₀ from road source, local non-road source, and total source) in pregnancy were estimated using dispersion models and a full maternal residential history for 12,020 births from the Avon longitudinal study of parents and children (ALSPAC) cohort in 1990-1992 in the Bristol area. Information on birth outcomes were obtained from birth records. Maternal sociodemographic and lifestyle factors w
