Description
Objective
To investigate the relation between exposure to both air and noise pollution from road traffic and birth weight outcomes.
Design
Retrospective population based cohort study.
Setting
Greater London and surrounding counties up to the M25 motorway (2317 km2), UK, from 2006 to 2010.
Participants
540 365 singleton term live births.
Main outcome measures
Term low birth weight (LBW), small for gestational age (SGA) at term, and term birth weight.
Results
Average air pollutant exposures across pregnancy were 41 μg/m3 nitrogen dioxide (NO2), 73 μg/m3 nitrogen oxides (NOx), 14 μg/m3 particulate matter with aerodynamic diameter <2.5 μm (PM2.5), 23 μg/m3 particulate matter with aerodynamic diameter <10 μm (PM10), and 32 μg/m3 ozone (O3). Average daytime (LAeq,16hr) and night-time (Lnight) road traffic A-weighted noise levels were 58 dB and 53 dB respectively. Interquartile range increases in NO …
