Table 3 Continuous associations with physical function and frailty (beta coefficients (95% CIs) and corresponding p-values)

From: Dose-response association between physical activity and sedentary time categories on ageing biomarkers

Outcome Moderate-to-vigorous physical activity time Light physical activity-to-sedentary behavior ratio
Beta (95% CI) a p-value Beta (95% CI) b p-value
Short Physical Performance Battery (n = 765) 0.03 (0.02, 0.04) < 0.001 0.96 (0.09, 1.82) 0.030
Frailty Trait Scale (n = 749) −0.18 (− 0.22, − 0.14) < 0.001 −5.39 (− 9.34, − 1.44) 0.008
  1. Adjusted linear regression models were fitted for physical function and frailty outcomes. The models were controlled for: age, sex, education, income, marital status, moderate-to-vigorous physical activity time, light physical activity-to-sedentary time ratio, and accelerometer wear-time.
  2. Bold indicates statistical significance at α = 0.05
  3. aBeta coefficients represent a one minute increase in moderate-to-vigorous physical activity time per day
  4. bBeta coefficients represent a one unit increase in the light physical activity-to-sedentary behavior ratio
