Isotemporal associations for substitutions in activity with cardiovascular risk and functional burden
| Substitution of one SD* of activity at baseline (n=1648) | |||
|---|---|---|---|

| OR (95% CI) | |||
|

| Replace ST with 84 mins of LPA | Replace ST with 24 mins of MVPA | Replace LPA with 24 mins of MVPA | |
| Cardiovascular risk and functional burden | 0.94 (0.83, 1.06) | 0.85 (0.75, 0.96) | 0.86 (0.75, 0.99) |
| Substitution of one SD* change in activity from baseline to 10-year follow-upb (n=759) | |||
|
| |||
| OR (95% CI) | |||
|
|
|||
| Replace ST with 84 mins of LPA | Replace ST with 24 mins of MVPA | Replace LPA with 24 mins of MVPA | |
|
| |||
| Cardiovascular risk and functional burden | 1.02 (0.84, 1.24) | 0.62 (0.49, 0.79) | 0.62 (0.48, 0.79) |
Models adjusted for 2 activities (besides activity being replaced) age, sex, race, study center, education, health insurance, employment status, smoking status, alcohol consumption, drinking status, sleep quality, and total wear time;
b
10-year change models also adjusted for baseline ST and MVPA;
ST: sedentary time; LPA: light intensity physical activity; MVPA: moderate to vigorous intensity physical activity; SD: Standard Deviation; mins: minutes;
*
1 SD of LPA: 84 minutes; 1 SD of MVPA: 24 minutes
