Prenatal Internal Exposure to Polycyclic Aromatic Hydrocarbons, Maternal Genetic Susceptibility, and Child Growth Trajectories: Evidence from a Prospective Cohort Study.

Abstract excerpt

Prenatal exposure to polycyclic aromatic hydrocarbons (PAHs) is a widespread environmental health concern, yet its impact on early childhood growth trajectories remains poorly understood. In a prospective birth cohort in China (PKUBC-T), we identified distinct growth trajectories from birth to age 3 years using K-means clustering for longitudinal data (N = 1467) and measured 16 plasma PAHs in first-trimester...
