Abstract

Abstract

Objective To investigate the relationship between maternal environmental exposure during pregnancy and neonatal preterm delivery and low birth weight. Methods A self-designed questionnaire of environmental exposure during pregnancy was used, including factors such as passive smoking, ventilation, decoration, gutter, garbage station, chemical plant, high temperature, radiation, noise, dust and others. A questionnaire survey was conducted among pregnant women in the Chinese Maternal Pregnant Women Cohort Study, and the birth status of newborns was collected. Correlation analysis was carried out by logistic liner regression model. Results A total of 6 189 pregnant women recruited were in our study, including 283 cases of premature birth (4.57%) and 202 cases of low birth weight (3.26%). After adjusting for age, nationality, registered residence, education, occupation, annual family income, pre-pregnancy body mass index (BMI) and parity other factors, logistic liner regression model showed that pregnant women exposed to noise during pregnancy were more likely to have preterm delivery than those who were not exposed to noise during pregnancy (OR=1.668, 95% CI: 1.197-2.323). Pregnant women who were exposed to high temperatures at work or at home during pregnancy were more likely to have preterm labor than those who were not (OR=2.237, 95% CI: 1.171-4.274). For other environmental exposure factors, no association were found with preterm delivery and low birth weight. Conclusions Exposure to noise and high temperature during pregnancy may be the risk factors of preterm delivery. Actively carry out health education to reduce the noise and high temperature exposure of pregnant women in the working and living environment, may help to reduce the risk of preterm delivery.
