Table is based on imputed dataset. ¥p value <0.20, †p value <0.10; ‡p value <0.05. Values in bold indicate statistical significance (p < 0.05).
Values represent beta’s and 95% confidence intervals derived from multiple logistic regression analyses.
*Adjusted for socio-demographic factors: child’s ethnicity, maternal educational level, household income, and maternal employment status.
**Additionally adjusted for family lifestyle factors: child’s breakfast skipping, consumption of high-calorie snacks, consumption of sugar-containing beverages, maternal BMI, and paternal BMI.
***Additionally adjusted for other sedentary behaviors and physical activity behaviors.
