A Compositional Analysis of Physical Activity, Sedentary Time, and Sleep and Associated Health Outcomes in Children and Adults with Cystic Fibrosis

This study sought to investigate the association of light physical activity (LPA), moderate-to-vigorous physical activity (MVPA), sedentary time (SED), and sleep with lung function in children and adults with CF. In total, 86 children (41 females; 13.6 ± 2.8 years; FEV1%predicted: 86 ± 1%) and 43 adults (21 females; 24.6 ± 4.7 years; FEV1%predicted: 63 ± 21%) with CF participated in this study. Wrist-worn accelerometery was used to assess PA, SED and sleep. Compositional linear regression models were conducted following normalisation via isometric log-ratio transformations. Sequential binary partitioning was applied to investigate the impact of reallocating 10 to 30 min between each behaviour on FEV1%predicted. A decline in FEV1%predicted was predicted with the reallocation of 30 min from MVPA to SED or LPA or sleep to any other behaviour in children (−3.04–−0.005%) and adults (−3.58–−0.005%). Conversely, improvements in FEV1%predicted were predicted when 30 min was reallocated to MVPA from LPA or SED in children (0.12–1.59%) and adults (0.77–2.10%), or when 30 min was reallocated to sleep from any other behaviour in both children (0.23–2.56%) and adults (1.08–3.58%). This study supports the importance of MVPA and sleep for maintaining and promoting lung function in people with CF

A qualitative study of physiotherapy education for parents of toddlers with cystic fibrosis

AbstractBackgroundEducation and daily physiotherapy are often highlighted as difficult and stressful tasks for parents of young children with cystic fibrosis. This study aimed to identify factors that impair the delivery and retention of physiotherapy education for parents of these children and factors that impair effective physiotherapy treatment in the home environment.MethodsA focus group of physiotherapists and six semi-structured interviews of parents with children with cystic fibrosis were conducted. The qualitative method of Grounded Theory was used to analyse the information and develop key themes.ResultsMajor emergent themes were ‘transitions’, ‘psychological distress’ and ‘connectedness’. Factors influencing the effectiveness of parental physiotherapy education include the large volumes of information, appropriateness of educational resources and timing of education. Factors influencing home physiotherapy management for toddlers include mastering techniques, the transition from infant to toddler and time management.ConclusionPhysiotherapy education and management were key causes of psychological distress for parents. This research suggests that significant targeted development of educational resources is warranted, in conjunction with dedicated and ongoing formal psychosocial support for parents

Current best practice in rehabilitation in interstitial lung disease

Interstitial lung disease (ILD) is a group of chronic respiratory diseases characterized by dyspnoea on exertion and decline in health-related quality of life (HRQL). People with ILD experience significant exercise limitation with contributors that include ventilatory limitation, impaired gas exchange, decreased cardiac function and skeletal muscle dysfunction. Pulmonary rehabilitation (PR) is well established in patients with chronic obstructive pulmonary disease (COPD) as a means to overcome exercise limitation and improve activity-related dyspnoea. There is increasing evidence for similar effects of PR in people with ILD. This review discusses the evidence for PR in ILD, outlines the essential components of PR in this population, and highlights special considerations for exercise training in people with ILD. Possible future directions for PR research in people with ILD are explored

Pulmonary rehabilitation referral and participation are commonly influenced by environment, knowledge, and beliefs about consequences: a systematic review using the Theoretical Domains Framework

Question: What are the barriers and enablers of referral, uptake, attendance and completion of pulmonary rehabilitation for people with chronic obstructive pulmonary disease (COPD)? Design: Systematic review of qualitative or quantitative studies reporting data relating to referral, uptake, attendance and/or completion in pulmonary rehabilitation. Participants: People aged >18 years with a diagnosis of COPD and/or their healthcare professionals. Data extraction and analysis: Data were extracted regarding the nature of barriers and enablers of pulmonary rehabilitation referral and participation. Extracted data items were mapped to the Theoretical Domains Framework (TDF). Results: A total of 6969 references were screened, with 48 studies included and 369 relevant items mapped to the TDF. The most frequently represented domain was ‘Environment’ (33/48 included studies, 37% of mapped items), which included items such as waiting time, burden of illness, travel, transport and health system resources. Other frequently represented domains were ‘Knowledge’ (18/48 studies, including items such as clinician knowledge of referral processes, patient understanding of rehabilitation content) and ‘Beliefs about consequences’ (15/48 studies, including items such as beliefs regarding role and safety of exercise, expectations of rehabilitation outcomes). Barriers to referral, uptake, attendance or completion represented 71% (n = 183) of items mapped to the TDF. All domains of the TDF were represented; however, items were least frequently coded to the domains of ‘Optimism’ and ‘Memory’. The methodological quality of included studies was fair (mean quality score 9/12, SD 2). Conclusion: Many factors – particularly those related to environment, knowledge, attitudes and behaviours – interact to influence referral, uptake, attendance and completion of pulmonary rehabilitation. Overcoming the challenges associated with the personal and/or healthcare system environment will be imperative to improving access and uptake of pulmonary rehabilitation.
