Table 3 Odds ratio for premature births and change in birth weight for full term births for each 10 μg/m 3 increment in PM 2.5 for various exposure periods
Exposure | Birth weight Change (in grams) (95% CI) | OR (95% CI) |
|---|---|---|
Last month (30 days prior to birth) | −8.80*** (−10.32 to −4.44) | 1.00 (0.96 to 1.04) |
Last trimester (90 days prior to birth | −9.20*** (−15.00 to −3.30) | 0.99 (0.94 to 1.03) |
Entire birth period | −13.80*** (−21.10 to −6.05) | 1.06*** (1.01 to 1.13) |
