ObjectivesElevated risk factors for a number of chronic diseases have been identified in lorry drivers. Unhealthy lifestyle behaviours such as a lack of physical activity (PA) and high levels of sedentary behaviour (sitting) likely contribute to this elevated risk. This study behaviourally phenotyped UK lorry drivers’ sedentary and non-sedentary behaviours during workdays and non-workdays and examined markers of drivers cardio-metabolic health.SettingA transport company from the East Midlands, UK.ParticipantsA sample of 159 male heavy goods vehicle drivers (91% white European; (median (range)) age: 50 (24, 67) years) completed the health assessments. 87 (age: 50.0 (25.0, 65.0); body mass index (BMI): 27.7 (19.6, 43.4) kg/m2) provided objective information on sedentary and non-sedentary time.OutcomesParticipants self-reported their sociodemographic information. Primary outcomes: sedentary behaviour and PA, assessed over 7 days using an activPAL3 inclinometer. Cardio-metabolic markers included: blood pressure (BP), heart rate, waist circumference (WC), hip circumference, body composition and fasted capillary blood glucose, triglycerides, high-density lipopreotein cholesterol, low-density lipoprotein cholesterol (LDL-C) and total cholesterol (TC) levels. These cardio-metabolic markers were treated as secondary outcomes.ResultsLorry drivers presented an unhealthy cardio-metabolic health profile (median (IQR) systolic BP: 129 (108.5, 164) mm Hg; diastolic BP: 81 (63, 104) mm Hg; BMI: 29 (20, 47) kg/m2; WC: 102 (77.5, 146.5) cm; LDL-C: 3 (1, 6) mmol/L; TC: 4.9 (3, 7.5) mmol/L). 84% were overweight or obese, 43% had type 2 diabetes or prediabetes and 34% had the metabolic syndrome. The subsample of lorry drivers with objective postural data (n=87) accumulated 13 hours/day and 8 hours/day of sedentary behaviour on workdays and non-workdays (p<0.001), respectively. On average, drivers accrued 12 min/day on workdays and 6 min/day on non-workdays of moderate-to-vigorous PA (MVPA).ConclusionLorry drivers demonstrate a high-risk cardio-metabolic profile and are highly sedentary and physically inactive. Interventions to reduce sitting and increase MVPA during breaks and leisure time to improve cardio-metabolic health are urgently needed. Educational programmes to raise awareness about diet and exercise are recommended.
Objectives:To identify the definitions used for treatment fidelity in the behaviour change literature and to explore the extent to which the assessment of fidelity has been reported according to the five domains by Bellg et al. Methods:Three data bases (Scopus, Medline Ovid and CINAHL) were searched.Results were limited to studies published between 2012 and 2015.Definitions/summaries of treatment fidelity used were recorded. Methods for assessing/monitoring treatment fidelity were extracted, summarised and categorised according to the five domains.Results: Sixty-five papers were included for analysis. A definition of treatment fidelity was provided by n=34 studies; n=9 defined fidelity according to Bellg et al. In the context of treatment fidelity n=9 (13.8%) reported on study design; n=22 (33.8%) reported on an element of training of providers; n=59 (90.7%) papers reported on delivery of treatment; n=13 (20%) reported on receipt of treatment; and n=10 (15.3%) reported on enactment of treatment skills. Conclusion:The definitions of treatment fidelity in the literature and the extent to which it has been reported were limited. Delivery of treatment was the most frequently reported component of treatment fidelity but other important aspects were poorly reported. The potential consequence of this is that translation of research interventions into clinical practice may not be optimised.Key words: Treatment fidelity; behaviour change; physiotherapy; physical activity; exercise 2 2 IntroductionThe concept of treatment fidelity has evolved over time;1 and there does not appear to be one single agreed definition. Treatment fidelity can refer to all the mechanisms that ensure an intervention tests its hypothesis and that all the components of the intervention are implemented as outlined in the protocol. There does however appear to be an agreement in the literature of the importance of assessing and monitoring treatment fidelity. Firstly treatment fidelity increases the internal validity of a trial such that the results of the trial are directly attributable to the intervention. 2 Good treatment fidelity also increases the reproducibility of the trial by enhancing external validity; this increases to the extent to which the results can be generalised to the clinical setting. 1-3 Additionally optimisation of fidelity can also increase the statistical power of an intervention as the varability in delivery has been minimised. 1,[3][4] If the results of a trial are found to be non-significant and fidelity has not been monitored, it would be unclear if the results were due to an ineffective intervention or whether key elements of the trial were not implemented as planned. Conversely lack of attention to treatment fidelity could find an intervention to be effective due to extra treatment factors, potentially resulting in an ineffective intervention being found to be significant in a trial and subsequent implemented in clinical practice. [2][3]5 Finally fidelity monitoring can aid researchers in moving forward and refining int...
Pulmonary rehabilitation (PR) may not suit all individuals with chronic obstructive pulmonary disease (COPD) and may not result in increased physical activity. Higher levels of physical activity are associated with reduced mortality and morbidity. The aim of this study was to assess the feasibility of conducting a trial to investigate the effectiveness of a clinician-facilitated physical activity intervention (PAI) versus PR in improving physical activity in patients with COPD referred to PR. In this randomised controlled mixed methods feasibility study, all patients referred to PR who were eligible and willing were assessed at baseline and then randomised to the PAI or to PR. The assessments were repeated post-intervention and at 3-month follow-up. The main outcome was step count measured by Actigraph. Semi-structured interviews were conducted post-intervention. The N = 50 patients; mean (SD) age, 64.1(8.6) years, 24M were recruited and randomised; N = 23 (PAI) and n = 26 (PR): one patient was excluded from the analysis as that person did not meet the GOLD diagnostic criteria. Key feasibility criteria were met; recruitment was 11%, dropouts in PAI were 26% (n = 6) and 50% (n = 13/26) PR. Participants in both groups experienced a range of health benefits from their respective programmes. The PAI appears to be effective in increasing step counts in people with COPD: mean change (standard deviation) [confidence interval] for the PAI group was 972.0(3230.3)[-1080.3 to 3024.4], n = 12 and 4.3(662.7)[-440.9 to 449.5], n = 11 for the PR group. The PAI met all domains of fidelity. This study provides key information to inform a future-randomised controlled trial in physical activity.
The aim of this study is to explore participants' views and experiences of an eHealth phase 3 cardiac rehabilitation (CR) intervention: Physical Activity Towards Health (PATHway). Sixty participants took part in the PATHway intervention. Debriefs were conducted after the six-month intervention. All interviews were audio recorded and transcribed verbatim. Transcripts were analysed with Braun and Clarke's thematic analysis. Forty-four (71%) debriefs were conducted (n = 34 male, mean (SD) age 61 (10) years). Five key themes were identified: (1) Feedback on the components of the PATHway system, (2) Motivation, (3) Barriers to using PATHway, (4) Enablers to using PATHway, and (5) Post programme reflection. There were a number of subthemes within each theme, for example motivation explores participants motivation to take part in PATHway and participants motivation to sustain engagement with PATHway throughout the intervention period. Participant engagement with the components of the PATHway system was variable. Future research should focus on optimising participant familiarisation with eHealth systems and employ an iterative approach to development and evaluation.
Background Pulmonary rehabilitation (PR) is recommended in the treatment of people with idiopathic pulmonary fibrosis (IPF). Little is known about the experiences of people with IPF of PR. Due to Covid-19 there has been a rapid shift of PR services to remote/virtual delivery. Objective To explore people living with IPFs experience of a virtual PR (VPR) programme. Methods All patients with a diagnosis of IPF in a stable phase of the disease were invited to participate in virtual PR: a 10 week exercise programme delivered twice-weekly for one hour. One-to-one semi- structured interviews were conducted within one week following the programme. All interviews were recorded, transcribed and analysed using Braun and Clarke thematic analysis by two independent assessors. Results N=13 participants took part in the semi-structured interviews, mean (standard deviation (SD)) age 69.5(10.4) years; 7M:6F. Mean (SD) FEV1 2.6(0.3)L, FVC 2.9(0.4)L. Four key themes were identified: 1) The impact of VPR on health and outlook, (2) The reality of VPR, (3) Being active after VPR and (4) Living with IPF during the COVID-19 Pandemic. Participants reported high levels of enjoyment and engagement with the programme regardless of the health benefits experienced. Most participants expressed a desire for a longer programme. Participants expressed different levels of maintenance with exercise since finishing the programme, specific motivators and strategies for maintenance included lung transplant, the maintenance of benefits from the programme and social support. COVID-19 and the restrictions imposed had some negative impacts on some participants lives, engaging with PR helped overcome some of these. Conclusion Despite the progressive nature of IPF, all participants expressed high levels of enjoyment with the programme. Future research should explore strategies for maintenance post PR and the optimum duration of PR for people with IPF.
