  1. Model 1: No adjustment
  2. Model 2: Adjustment for age, body mass index, ethnicity, smoking status, employment status, differences in time between baseline and accelerometry protocol, accelerometry wear time, season of accelerometer wear (two orthogonal sine functions), severe medical conditions and grip strength
  3. Model 3: Adjustment for all covariates included in Model 2 plus mutual adjustment for each other. Information about model adjustment is provided in greater detail in Additional file 1: Table S1
  4. Note: The beta coefficients and 95% confidence intervals (values in parentheses) are reported on a log scale. Abbreviations: DIY Do-It-Yourself, MVPA moderate-to-vigorous physical activity, SD Standard Deviation
