Multivariable Cox proportional hazards models were used to investigate the associations between 24-hour movement behaviors (sleep, sedentary behavior, light-intensity physical activity [LIPA], and moderate-to-vigorous intensity physical activity [MVPA]) and the risk of CCD.

Greater sedentary behavior was associated with an increased risk of CCD (hazard ration [HR], 1.05; 95% confidence interval [CI], 1.02-1.08), whereas higher MVPA was associated with a lower risk (HR, 0.83; 95% CI, 0.75-0.92).

Reallocating 30 min/day to MVPA from other movement behaviors was associated with a 4% lower risk of CCD (HR, 0.96; 95% CI, 0.93-0.98). Conversely, reallocating 30 minutes/day to sedentary behavior was associated with a 3% increased risk (HR, 1.03; 95% CI, 1.01-1.05).
