Single, partition, and isotemporal substitution models examining the relation between changes in time spent (hours p/day) in sedentary, light and moderate-to-vigorous intensity activity and hand grip strength (n = 353)
| Models | Sedentary, B (95 % CI) | Light activity, B (95 % CI) | MVPA, B (95 % CI) |
|---|---|---|---|
| Single | −0.338 (−0.717, 0.041) | 0.258 (−0.111, 0.627) | 0.603 (−1.031, 2.236) |
| Partition | −0.298 (−0.687, 0.091) | 0.211 (−0.164, 0.586) | 0.212 (−1.462, −1.887) |
| Isotemporal substitution | |||
| Replace sedentary | Dropped | 0.509 (0.000, 1.019) | 0.511 (−1.139, 2.161) |
| Replace light activity | −0.509 (−1.019, 0.000) | Dropped | 0.002 (−1.760, 1.763) |
| Replace MVPA | −0.511 (−2.161, 1.139) | −0.002 (−1.763, 1.760) | Dropped |
Regression coefficients (95 % CI) were adjusted for age, sex, ethnicity, height and school deprivation
