The correlation between maternal exposure to air pollution during the third trimester of pregnancy and the risk of jaundice in newborns
| (Subgroup I) (n = 7722) | (Subgroup II) (n = 6336) | T value | P value | |
|---|---|---|---|---|
| PM2.5 (μg per m3) | 69.98 ± 16.06 | 73.79 ± 16.76 | −13.455 | 0.000 |
| SO2 (μg per m3) | 4.71 ± 2.19 | 5.41 ± 2.47 | −17.564 | 0.000 |
| CO (mg per m3) | 1.22 ± 4.06 | 1.77 ± 7.41 | −5.513 | 0.000 |
Maternal exposure to each of PM2.5, SO2 and CO had statistically significant, positive correlation with the severity of neonatal jaundice
