Note: * p < 0.05. a Statistical tests between those with mild ID and moderate ID for physical activity (PA) levels, sedentary behavior, and physical fitness variables were adjusted for age and sex. Abbreviations: 6MWT, six-minute walk test; BMI, body mass index; HC, hip circumference; LPA, light-intensity physical activity; MVPA, moderate-to-vigorous physical activity; SB, sedentary behavior; WC, waist circumference.
