^aBeta coefficients are interpreted as the change in BMI Z-score when each PBDE is increased from low (< 80th percentile) to high (≥ 80th percentile) across 10 multiply imputed datasets
^bModel 1: Minimally adjusted for age and age² (centered at age 5) and sex
^cModel 2: Fully adjusted for maternal parity (primiparous/multiparous), age at birth, ethnicity (Dominican/African American), receipt of public assistance (yes/no), completed high school (yes/no), partnership status (partnered/single), and linear and quadratic child age at visit (centered at age 5) and child sex
^dP-value Thresholds: ***P ≤ 0.001; **P ≤ 0.05, *P ≤ 0.1
