Abstract:
Objective: This retrospective observational study investigates the association
between maternal exposure to air pollutants and pregnancy adverse
outcomes in low urbanization areas. Methods: We used multivariate
regression analysis to estimate, in the Como province (2005–2012), the
effects of NOx, NO2, SO2, O3, CO, and PM10 on low birth weight (LBW),
babies small for gestational age (SGA), and preterm birth (PTB).
Results: PTB was inversely associated with high (5.5mg/m3) exposure to
SO2 (adjusted odds ratio [aOR]¼0.74, 95% confidence interval [95%
CI]¼0.58–0.95) and to CO (1.8 mg/m3, aOR¼0.84, CI¼0.72–0.99).
PTB risk increased with second trimester exposure to NOx (118.3mg/m3,
aOR¼1.53, CI¼1.25–1.87), while LBW risk increased with third trimester
PM10 (56.1mg/m3, aOR¼1.44, CI¼1.03–2.02). SGAwas inversely associated
with third trimester NOx (115.8mg/m3, aOR¼0.89, CI¼0.79–0.99).
Conclusions: Exposure to SO2 and CO seems to postpone delivery: a longer
gestation could compensate for maternal hypoxemic-hypoxic damage
