  1. aComplete case analysis (n = 1329 in each model): men who met the inclusion criteria (Fig. 1) and who had at least two valid hours of wear time in each period of the day (morning 7:00-12:59, afternoon 13:00-18:59, evening 19:00-22:59). A valid hour is defined as an hour with ≥45 min of wear time
  2. bβ coefficient represents the difference in percent of time spent in SB (Model 1) and LIPA (Model 2) compared to the reference category of each explanatory variable. Models are multilevel linear regression models mutually adjusted for season of accelerometer wear, region of residence plus all explanatory variables listed in the table
