This longitudinal study examined the relationship between accelerometer-measured sedentary time (ST), light physical activity (LPA), and moderate-to-vigorous physical activity (MVPA) and fat mass in 6059 children aged 11–24 years. Each minute/day of ST was associated with a 1.3 g increase in fat mass, while each minute/day of LPA and MVPA was associated with a 3.6 g and 1.3 g decrease, respectively. Persistently achieving ≥60 min/day of MVPA was linked to a greater fat mass reduction, partly mediated by decreased insulin and LDL cholesterol. LPA showed a similar or stronger fat mass-lowering effect than MVPA, suggesting its importance in obesity prevention.
