BF, body fat percentage (%); BMI, body mass index (kg·m−2); FFMI, fat-free mass (kg·m−2); FMI, fat mass (kg·m−2); VPA, vigorous physical activity; MVPA, moderate to vigorous physical activity. N = 310 – 311 per quintile.
a
Quintile of body composition range from 1 (lowest BF, BMI, FFMI, and FMI) to 5 (highest BF, BMI, FFMI, and FMI).
