  1. BMI body mass index, LDL low density lipoprotein, HDL high density lipoprotein, HOMA homeostasis model assessment, SED sedentary time, LPA light physical activity, MPA moderate physical activity, VPA vigorous physical activity, MVPA moderate-to-vigorous physical activity. *Odds ratio; **The composite score includes waist:height ratio, systolic blood pressure, total: HDL ratio, triglycerides, HOMA, and the Andersen test. Intensity-specific PA is calculated using the Evenson cut points [29]; ***The guideline PA levels is defined as a mean of ≥60 min of MVPA per day
