OBJECTIVE: The aim of this study was to evaluate the effects of PM10 on birth outcomes using a prospective cohort of pregnant women. METHODS: The multicenter prospective study was conducted in Korea from 2001 to 2004. To estimate the effects of PM10 exposure on birth outcomes, the logistic and linear regression model and the generalized additive model for nonlinear relationships were used. RESULTS: Stillbirths were affected by PM10 level during the third trimesters (OR = 1.10, 95% CI = 1.02-1.14), and birth defects were influenced by the PM10 exposure during the second trimesters (OR = 1.16, 95% CI = 1.00-1.34). Intrauterine growth retardation was affected by the first trimester's PM10 exposure. On the other hand, premature birth was affected by the PM10 exposure during the third trimester, and low-birth-weight births were affected by the PM10 level during entire trimesters of pregnancy. CONCLUSIONS: PM10 exposure during pregnancy may result in adverse birth outcomes with different critical periods.
