BACKGROUND: Few studies have examined sedentary behaviour in chronic respiratory disease. The limited evidence suggests that increased levels of sedentary behaviour are associated with increased mortality.
OBJECTIVES: This study aimed to compare the level of self-reported sedentary behaviour in people with chronic obstructive pulmonary disease (COPD) and bronchiectasis as well as to identify associations between sedentary time with functional performance measures and health-related quality of life in the chronic respiratory disease group.
METHODS: An observational study design was used. Participants completed the Sedentary Behaviour Questionnaire from which average sedentary time (hours/day) was determined. Functional performance was measured using the six-minute walk test, the four-metre gait speed test and the five sit-to-stand test. Health-related quality of life was measured using the St George's Respiratory Questionnaire. Sedentary time was compared between groups using an unpaired t-test. Univariate analysis explored relationships amongst variables.
RESULTS: The convenience sample consisted of 103 people with COPD [52% male; mean±SD age: 73±9 years, FEV1% predicted: 56±23] and 33 people with bronchiectasis [52% male; 74±8 years, FEV1% predicted: 69±25]. Average self-reported sedentary time in COPD was 7.6±2.7 hours/day and in bronchiectasis was 8.0±4.1 hours/day, with no between-group difference (-0.4, 95% CI -1.7, 0.8). No associations were found between sedentary time and any functional performance outcome or with health-related quality of life.
CONCLUSION: There was no difference in the high sedentary time between people with COPD and bronchiectasis. Sedentary behaviour was not associated with functional performance or disease-related health-related quality of life in people with chronic respiratory disease.
