  1. Ta Average ambient air temperature, tLBW term low birth weight, SGA small for gestational age. Odds ratios were adjusted for calendar month, year of birth, particulate matter < 2.5 μm (PM2.5), maternal age at birth, gravidity, parity, ethnicity, newborn sex, census-level poverty index and population density
