  1. Overall PM10 and PM2.5 emissions and UCB adducts were log transformed. Models were adjusted for maternal occupation (housewife or employed), maternal age, self-reported environmental tobacco exposure (at least one active smoker living in the same address) and parity.
  2. Bold numbers represent statistical significance (p < 0.05).
