Key Points
- To assess physical activity and sedentary behaviour levels in patients entering a phase III cardiac rehabilitation program and identify at-risk subgroups.
- Cross-sectional analysis of patients with cardiovascular disease (CVD) completing baseline assessments and wearing accelerometers for 7 days.
- Patients engaged in supervised exercise sessions 2-3 times per week.
- Group differences were analyzed using t-tests, correlations, and multivariable regression models.
- Patients averaged 45.89 minutes/day of moderate-to-vigorous physical activity (MVPA) and 11.06 hours/day of sedentary behaviour (SB).
- Women had lower MVPA compared to men, performing 31.1 min/day vs 45.1 min/day (p=.041).
- Those with diabetes accumulated less MVPA (43.7 vs 45.9 min/day; p=.011) and completion of phase II CR was associated with lower SB percentage (p=.032).
Structured PICO
PPopulation190 CVD patients entering a phase III cardiac rehabilitation program, mean age 62±10 years, 17.9% women, 85.8% with coronary artery disease, 84.2% completed phase II CR.
IInterventionPhase III cardiac rehabilitation program (supervised 60-min exercise sessions, 2-3x/week) with 7-day accelerometer monitoring
OOutcomePhysical activity (moderate-to-vigorous and light) and sedentary behaviour levels measured by 7-day accelerometer
In patients entering phase III cardiac rehabilitation, sedentary behavior remains high despite meeting physical activity guidelines, with women, diabetics, and those with lower fitness or no prior phase II rehab identified as vulnerable subgroups requiring tailored support.
