^aThe analysis of creatinine-adjusted concentrations of BPA, BPS, and BPF is presented in Table S3, Supporting Information.

^bRace/ethnicity was categorized based on self-reported data into Hispanic (including Mexican and non-Mexican Hispanic), non-Hispanic white, non-Hispanic black, and other race/ethnicity.³⁷

^cSelf-reported education was grouped as less than high school, high school, and college or higher.³⁷

^dFamily IPRs were categorized as ≤1.30, 1.30–3.50, and >3.50.^37,50

^eSelf-reported smoking was classified as never smokers who smoked less than 100 cigarettes in their lifetime; current smokers who currently smoke cigarettes; and ever smokers who smoked more than 100 cigarettes in their lifetime but do not smoke currently.³⁷

^fSelf-reported physical activity was used to derive MET minutes per week according to the Global Physical Activity Questionnaire Analysis Guide⁷¹ and categorized as <600, 600–1200, and >1200 MET min/week.³⁷

^gAlcohol intake was categorized as non-drinker (0 g/day), moderate drinker (0.1–28 g/day for men and 0.1–14 g/day for women), or heavy drinker (≥28 g/day for men and ≥28 g/day for women).⁵¹
