Objective: To analyze the association between pesticide exposure and adverse pregnancy outcomes in women from the rural areas of China. Methods: Data of"National Free Preconception Health Examination Project (NFPHEP)"from January 2010 to December 2012 was used for analysis. A total of 248 501 families that were planning to deliver a baby in the next 6 months were enrolled. Data on paternal exposure to pesticides before or during pregnancy was collected through questionnaires, with related outcomes on pregnancy recorded by doctors. Results: Among all the 248 501 participants, 1 806 (0.74%) women and 2 653 (1.09%) men reported to have been exposed to pesticide before pregnancy, with 505 (0.21%) reported of having been exposed to pesticide during the period of pregnancy. Maternal exposure to pesticide was found a risk factor related to stillbirth (OR=3.37, 95%CI: 2.05-5.55), peculiar smell pregnancy (OR=3.17, 95%CI:1.18-8.55) and low birth weight (OR=7.56, 95% CI: 5.36-10.66). Paternal exposure to pesticide was also found related to miscarriage (OR=1.37, 95% CI: 1.03-1.80), low birth weight (OR=3.65, 95% CI:1.51-8.84), or giant infant (OR=0.64, 95%CI: 0.44-0.93). Maternal exposure to pesticide during pregnancy appeared a risk factor on miscarriage (OR=4.65, 95% CI: 3.47-6.24). Other adverse outcomes on pregnancy would include premature birth and high birth weight. Conclusion: Parental pesticide exposure appeared a risk factor on stillbirth, peculiar smell pregnancy, low birth weight and miscarriage.
