The effect of the interaction between phthalate levels and BMI at 3–5 years of age on liver enzyme levels at 10–15 years of age based on sex. MBzP (mono-benzyl phthalate), MEHP [mono(2-ethylhexyl) phthalate], MnBP (mono-n-butyl phthalate). AST; aspartate aminotransferase, γ-GTP; gamma-glutamyl transferase. Tertiles of Phthalate at 3–5 years of age: MBzP(μg/g creatinine): T1: ≤ 7.26; T3: > 16.80; MEHP(μg/g creatinine): T1: ≤ 17.17; T3: > 31.69;; MnBP(μg/g creatinine): T1: ≤ 102.16; T3: > 182.81. *Adjusted for age, sex, BMI, mother’s education level, monthly household income at 3–5 years of age, second-hand smoke exposure, and physical inactivity level at 10–15 years of age
