Regression analysis. Data on MPA is shown in Supplementary material, Table S3. Determinants are dummy exposure variables for physical activities for comparison between the reference group (No-MVPA, and No-VPA, T0) and tertiles of MVPA and VPA (T1–3). Data are expressed as unstandardized beta coefficient with 95% confidence interval (95% CI). MVPA = moderate-to-vigorous physical activity, VPA = vigorous physical activity, MPA = moderate physical activity. T = tertile
Basic model = age and education
Model 1 = Basic model + diet, smoking and alcohol use
Model 2 = Model 1 + 24-h urinary creatinine excretion
Model 3 = Model 1 + occupational MVPA
