Patients with high sedentary behaviour (≥ 480 min/day) had significantly lower physical function at discharge compared to those with low sedentary behaviour (mean SPPB score 10.5 vs 11.2 points, p=0.001).

Why the study?

Sedentary behaviour is linked to cardiovascular mortality and morbidity, but its relation with physical function in phase I cardiac rehabilitation is not well understood.

Does high sedentary behaviour reduce physical function in patients participating in phase I cardiac rehabilitation?

Population

353 patients participating in phase I cardiac rehabilitation

Comparison

High sedentary behaviour (≥ 480 min/day) vs low sedentary behaviour (< 480 min/day)

Design

Prospective multicentre cohort study

Key result

Patients with high sedentary behaviour (≥ 480 min/day) had significantly lower physical function at discharge compared to those with low sedentary behaviour (mean SPPB score 10.5 vs 11.2 points, p=0.001).

Overview

High sedentary time warrants caution in phase I CR but should not yet change practice; hypothesis-generating for interventional trials.

P

353 patients with cardiovascular disease participating in phase I cardiac rehabilitation, with a mean age of 69.6 years, evaluated for physical function at discharge.
E
Exposure
High sedentary behaviour (≥ 480 min/day of sitting time)

Comparator
Low sedentary behaviour (< 480 min/day of sitting time)
O
Outcome
Physical function assessed by the Short Physical Performance Battery (SPPB) score at dischargesurrogate

Main Result

Absolute Event Rate: 10.5% vs 11.2%

p-value: p=0.001

High sedentary behaviour during phase I cardiac rehabilitation is associated with significantly lower physical function at discharge, highlighting the need to minimize sitting time in hospitalized cardiac patients.

Limitations

  • Included several cardiac diseases requiring different treatments
  • Assessment of SB was by questionnaire and lacks objective measurements
  • Domain-specific SB was not analysed
  • Many patients hospitalized for short-term procedures were excluded, potentially leading to selection bias
  • Mechanism behind SB and other specific risk factors were not investigated
  • Could not investigate the relation between SB and prognosis such as rate of re-admission and mortality
  • Assessment of sedentary behaviour was by questionnaire and lacks objective measurements
  • Domain-specific sedentary behaviour was not analysed
  • Exclusion of short-term procedures may have led to selection bias
  • Mechanism behind sedentary behaviour and specific risk factors not investigated
  • Relation between sedentary behaviour and prognosis not investigated

Cite This Study

Izawa et al. (2023) conducted a cohort in Cardiovascular disease (n=353). High sedentary behaviour (≥ 480 min/day) vs. Low sedentary behaviour (< 480 min/day) was evaluated on Short Physical Performance Battery (SPPB) score at discharge (p=0.001). Patients with high sedentary behaviour (≥ 480 min/day) had significantly lower physical function at discharge compared to those with low sedentary behaviour (mean SPPB score 10.5 vs 11.2 points, p=0.001).
