^aBeta coefficients are interpreted as the change in BMI Z-score when each PBDE is increased from low (< 80th percentile) to high (>80th percentile) in models 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 with IPW
