Objectives: To document the experiences of people with chronic obstructive pulmonary disease (COPD) who underwent a behaviour change intervention to reduce sedentary behaviour (SB) in a clinical trial.
Design And Participants: Qualitative study using semi-structured interviews to explore perspectives of the behaviour change intervention and specific intervention components in people with stable COPD on the waitlist for pulmonary rehabilitation.
Setting: Three outpatient pulmonary rehabilitation programmes in Sydney, Australia.
Objective: Pulmonary rehabilitation programs that use minimal equipment for exercise training, rather than gymnasium equipment, would enable delivery of pulmonary rehabilitation to a greater number of people with chronic obstructive pulmonary disease (COPD). The effectiveness of minimal equipment programs in people with COPD is unclear. This systematic review and meta-analysis aimed to determine the effects of pulmonary rehabilitation using minimal equipment for aerobic and/or resistance training in people with COPD.

Design: Analysis of baseline data from a randomized clinical trial.
Setting: Sydney, Australia.
Introduction: This study aimed to determine whether a 6-week behaviour change intervention was more effective than a sham intervention for reducing sedentary behaviour (SB) in people with chronic obstructive pulmonary disease (COPD).
Methods: People with stable COPD on the waitlist for entry into pulmonary rehabilitation were recruited to this multicentre trial with randomisation (independent, concealed allocation) to either an intervention group or sham group, assessor blinding and intention-to-treat (ITT) analysis. The behaviour change intervention consisted of once weekly sessions for 6 weeks with a physiotherapist to reduce SB through education, guided goals setting and real-time feedback on SB.
Few studies have used 24-hour accelerometery to characterise posture and movement patterns in people with chronic obstructive pulmonary disease (COPD). This study aimed to quantify sedentary behaviour (SB), patterns of SB accumulation and physical activity (PA) in people with COPD, and to examine physiological and functional capacity correlates of total SB and patterns of SB accumulation. SB and PA were assessed continuously over seven days using thigh-worn accelerometery in people with COPD.

Methods: The sample comprised adults aged 16 years and older who participated in the Welsh Health Survey (2011-2015). The HRQoL was evaluated using the 36-item short form.
Background: Little is known about the association between different types of physical activity (PA) and chronic back conditions (CBCs) at the population level. We investigated the association between levels of total and type-specific PA participation and CBCs.
Methods: The sample comprised 60,134 adults aged ≥16 years who participated in the Health Survey for England and Scottish Health Survey from 1994 to 2008.
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.
Questions: In people with chronic obstructive pulmonary disease (COPD), are activity phenotypes (based on physical activity and recreational screen time) associated with mortality and cardiometabolic risk factors?
Design: Cohort study.
Participants: People with COPD aged≥40years and who were current or ex-smokers were identified from the 2003 Scottish Health Survey.
Outcome Measures: Data were collected regarding demographics, anthropometric measurements, medical history, physical activity, sedentary behaviour, health outcomes, and mortality.
Background: Regular physical activity is recommended for all people with chronic obstructive pulmonary disease (COPD), but the dose of physical activity required to gain mortality benefit in this population is not yet known. This aim of this study was to examine the associations of total and type-specific physical activity with mortality risk in people with COPD.
Methods: People with COPD aged ≥40 years were identified from the 1997 Health Survey for England and the 1998 and 2003 Scottish Health Survey cohorts.
Introduction: Replacing sedentary behaviour with light intensity physical activity (ie, activities classified as less than three metabolic equivalents, such as slow-paced walking) may be a more realistic strategy for reducing cardiometabolic risk in people with chronic obstructive pulmonary disease than only aiming to increase levels of moderate-vigorous intensity physical activity. Behaviour change interventions to reduce sedentary behaviour in people with chronic obstructive pulmonary disease have not yet been developed or tested.
Research Questions: Is a 6-week behaviour change intervention effective and feasible in reducing sedentary time in people with chronic obstructive pulmonary disease?
Design: This study will be a multi-centre, randomised, controlled trial with concealed allocation, assessor blinding, and intention-to-treat analysis, comparing a 6-week behaviour change intervention aimed at reducing sedentary time with a sham intervention in people with chronic obstructive pulmonary disease.
