N = 867	Number of Case	Model 1 a	Model 2 b	Model 3 c
Tertile 1 (n = 286)	42	1.000 (reference) d	1.000 (reference)	1.000 (reference)
Tertile 2 (n = 289)	28	0.623 (0.375, 1.037)	0.629 (0.371, 1.068)	0.614 (0.353, 1.069)

P for trend e	–	0.009	0.021	0.041

^aModel 1 are a crude univariate model;

^bModel 2 adjusted for age (continuous variable), BMI (continuous variable);

^c Model 3 additionally adjusted for race (han nationality, tujia nationality, miao nationality and other nationality), only one child (yes or no), father education (senior high school or below, college and postgraduate), mother education (senior high school or below, college and postgraduate), smoking status (never, occasionally, or regularly), drinking status (never, occasionally, or regularly), physical activity level (low, middle, and high), sleep quality (good or not), sleep duration (6-8 h/d or <6 and >8 h/d) and parent’s marital status (married, widowed and divorced)

^dAdjusted data are expressed as odds ratio (95% confidence intervals)

^ep for trend were obtained using multivariate logistic regression analyses
