BMI body mass index, CI confidence interval, PA physical activity, SLEEP sleep duration, ST screen time
Meeting the recommendations is defined as 鈮�180听min/day of physical activity (of which 鈮�60听min is moderate-to-vigorous physical activity), 鈮�1听h/day of screen time, and 10鈥�13听h/day of sleep
No significant differences in BMI z-scores were observed between meeting vs. not meeting the different recommendations
Physical activity was based on accelerometer data, and screen time and sleep duration were parent-reported
