Physical activity intensity distributions, stratified by sex for full-time and part-time employed participants at age 60-64 years. Values are median (IQR) daily durations (min/day). Time spent at 1 MET (not plotted) among women was 662 (605, 734) min/day and 619 (590, 734) min/day for non-full-time employed part-time, respectively, whilst the equivalent estimates in men were 662 (604, 748) min/day and 691 (619, 763) min/day. Inserts of each graph show zoomed view of intensity distribution in the MVPA (>3 METs) zone. All values have been normalised to bin size 0.25 METs.
