Prenatal ozone exposure is associated with children overweight and obesity: Evidence from the Shanghai Maternal-Child Pairs Cohort.

ABSTRACT: Prenatal ozone (O₃) exposure may disrupt normal offspring growth. However, epidemiological evidence that prenatal O₃ exposure affects the physical development of offspring early in life is far from adequate. A total of 4909 maternal-child pairs from the Shanghai Maternal-Child Pairs Cohort were included. A high-resolution random forest model was utilized to evaluate prenatal exposure levels of O₃ based on the home addresses of pregnant women. Group-based trajectory and mixed-effects models were used to assess associations between prenatal O₃ exposure and physical parameters. Each 10 μg/m³ increase in O₃ concentration was associated with 0.084, 0.048, and 0.082-unit increases in body mass index (BMI) for age Z score (BAZ), weight for ag
