Note: The chi-square trend test and robust Poisson regression analysis were used for analysis. Q1 was the reference group. Model 1: unadjusted; Model 2: adjusted for age, gender, boarding status, parental education level, alcohol consumption, BMI Z score, and growth retardation. a Pearson’s R = 0.056, p = 0.033 (a detailed table is in the Supplementary Materials). The bold p-value means “<0.05”.
