Abbreviations: OR, odds ratio; CI, confidence interval. Unconditional logistic regression was used to compute ORs and CIs between bisphenols and precocious puberty. The models were adjusted for child age, child residence, child body mass index (BMI), guardian education, parity, mother’s BMI, sleep duration, and time spent in outdoor activities. p value < 0.05.
