Physical Activity and Sedentary Behavior in People With Inflammatory Joint Disease: A Cross-Sectional Study

The challenges of measuring physical activity and sedentary behaviour in people with rheumatoid arthritis

The importance of sufficient moderate-to-vigorous physical activity as a key component of a healthy lifestyle is well established, as are the health risks associated with high levels of sedentary behaviour. However, many people with RA do not undertake sufficient physical activity and are highly sedentary. To start addressing this, it is important to be able to carry out an adequate assessment of the physical activity levels of individual people in order that adequate steps can be taken to promote and improve healthy lifestyles. Different methods are available to measure different aspects of physical activity in different settings. In controlled laboratory environments, respiratory gas analysis can measure the energy expenditure of different activities accurately. In free-living environments, the doubly labelled water method is the gold standard for identifying total energy expenditure over a prolonged period of time (>10 days). To assess patterns of physical activity and sedentary behaviour in daily life, objective methods with body-worn activity monitors using accelerometry are superior to self-reported questionnaire- or diary-based methods.

The challenge of exercise (non-)adherence: a scoping review of methods and techniques applied to improve adherence to physical activity and exercise in people with inflammatory arthritis

Objectives

The aims were to explore the nature of methods/techniques applied to improve adherence to physical activity (PA) and exercise in people with inflammatory arthritis and to identify whether studies were theory based and/or used behaviour change techniques (BCTs).

Methods

Searches were undertaken of English language articles within four databases: Embase, Medline, PsycINFO and Cochrane. Articles were included if they assessed adherence to a PA and/or exercise intervention. A narrative synthesis of the findings is reported.

Results

Of 1909 studies screened, 18 studies met inclusion criteria. Adherence was most frequently included as a secondary outcome. Reporting of adherence measures was poor, in that 13 studies did not use a validated measure of adherence, with only three validated measures being identified. The majority of studies were not theory driven (n = 13), although the health belief model was the most used theoretical framework (n = 5). Only two studies mentioned both theory and BCTs. Four studies reported components that were mapped onto BCTs, with goal setting being the most prevalent.

Conclusion

This scoping review found that adherence to PA and/or exercise interventions was rarely the focus of research, despite its importance in maintaining health in people with inflammatory arthritis. Where research has been conducted in this area, serious shortcomings were revealed, in that psychological theory, evidence-based BCTs derived from theory and valid adherence measures were not used to inform intervention design and target adherence, meaning that interventions were suboptimal. These results suggest that there is considerable room for improvement and that more high-quality research is required to investigate determinants of adherence and develop impactful interventions.

Barriers and facilitators to physical activity in people with an inflammatory joint disease: a mixed methods study

Background

Physical activity has been shown to be of great benefit to people with an inflammatory joint disease (IJD), however people with an IJD have been shown to be very inactive compared to the general population. The aims of this study were to explore 1) whether the transition from a National Health Service (NHS)-run exercise programme into exercising in the community could be achieved successfully; and 2) the barriers and facilitators during the transition period.

Methods

This study adopted a complementary mixed-methods study design including a qualitative approach using focus groups and a prospective cohort study. Descriptive statistics were used to summarise the cohort study data. All variables were assessed for normality of distribution using the Sharpiro-Wilk test. Paired t-tests or Wilcoxon tests were undertaken for two consecutive assessment timepoints; one-way repeated measures ANOVAs or Friedman’s tests for three consecutive assessment timepoints. Micro-interlocutor analysis was used to analyse the focus group data. Areas of congruence and incongruence were explored by confirming the statistical results against the qualitative results. The adapted ecological model of the determinants of physical activity was then used as a framework to describe the findings.

Results

A successful transition was defined as still exercising in the community 6-months post discharge from the NHS-run Inflammatory Arthritis Exercise Programme. This was self-reported to be 90% of the cohort. An individual barrier to physical activity in people with an IJD was found to be the unpredictable nature of their condition. Other barriers and facilitators found were similar to those found in the general population such as recreation facilities, locations, transportation and cost. Other facilitators were similar to those found in people living with other chronic long-term conditions such as the importance of peer support.

Conclusions

90% of the cohort data were defined as a successful transition. People with an IJD have similar barriers and facilitators to exercise as the general population and those living with other chronic long-term conditions. A barrier which appears to be unique to this population group is that of the unpredictable nature of their condition which needs to be considered whenever tailoring any intervention.

Gait rehabilitation for foot and ankle impairments in early rheumatoid arthritis: a feasibility study of a new gait rehabilitation programme (GREAT Strides)

Background

Foot impairments in early rheumatoid arthritis are common and lead to progressive deterioration of lower limb function. A gait rehabilitation programme underpinned by psychological techniques to improve adherence, may preserve gait and lower limb function. This study evaluated the feasibility of a novel gait rehabilitation intervention (GREAT Strides) and a future trial.

Methods

This was a mixed methods feasibility study with embedded qualitative components. People with early (< 2 years) rheumatoid arthritis (RA) and foot pain were eligible. Intervention acceptability was evaluated using a questionnaire. Adherence was evaluated using the Exercise Adherence Rating Scale (EARS). Safety was monitored using case report forms. Participants and therapists were interviewed to explore intervention acceptability. Deductive thematic analysis was applied using the Theoretical Framework of Acceptability. For fidelity, audio recordings of interventions sessions were assessed using the Motivational Interviewing Treatment Integrity (MITI) scale. Measurement properties of four candidate primary outcomes, rates of recruitment, attrition, and data completeness were evaluated.

Results

Thirty-five participants (68.6% female) with median age (inter-quartile range [IQR]) 60.1 [49.4–68.4] years and disease duration 9.1 [4.0–16.2] months), were recruited and 23 (65.7%) completed 12-week follow-up. Intervention acceptability was excellent; 21/23 were confident that it could help and would recommend it; 22/23 indicated it made sense to them. Adherence was good, with a median [IQR] EARS score of 17/24 [12.5–22.5]. One serious adverse event that was unrelated to the study was reported. Twelve participants’ and 9 therapists’ interviews confirmed intervention acceptability, identified perceptions of benefit, but also highlighted some barriers to completion. Mean MITI scores for relational (4.38) and technical (4.19) aspects of motivational interviewing demonstrated good fidelity. The Foot Function Index disability subscale performed best in terms of theoretical consistency and was deemed most practical.

Conclusion

GREAT Strides was viewed as acceptable by patients and therapists, and we observed high intervention fidelity, good patient adherence, and no safety concerns. A future trial to test the additional benefit of GREAT Strides to usual care will benefit from amended eligibility criteria, refinement of the intervention and strategies to ensure higher follow-up rates. The Foot Function Index disability subscale was identified as the primary outcome for the future trial.

Influence of perceived barriers and facilitators for physical activity on physical activity levels in patients with rheumatoid arthritis or spondyloarthritis: a cross-sectional study of 150 patients

Background

Barriers and facilitators to physical activity in inflammatory arthritis can be assessed through the Inflammatory arthritis FAcilitators and Barriers (IFAB) questionnaire. The objective was to measure the correlation between IFAB and self-reported physical activity levels.

Methods

This was an international, multicentric, cross-sectional study in 2019–20. Consecutive spondyloarthritis (axSpA), rheumatoid arthritis (RA) or psoriatic arthritis (PsA) patients completed the 10-item IFAB, which ranges from − 70 to 70 with lower scores indicating more barriers. Physical activity was measured by the IPAQ-S questionnaire, steps per day collected by smartphone, and psychological readiness to change by stages of behaviour change. Spearman correlations and multivariable linear regression were calculated.

Results

Of 245 patients included, 150 were analysed: 69 (46%) axSpA, 63 (42%) RA, 18 (12%) PsA. Mean age was 48.6 years (standard deviation, SD 17.1), mean disease duration 11.7 (10.1) years and 60% were women. Barriers to physical activity were moderate: mean IFAB, 6 (SD 19.2); 39 (26%) patients scored less than − 5, corresponding to significant barriers. The mean physical activity was 2837 (SD 2668, median 1784) MET-minutes per week. The IPAQ-S questionnaire was correlated with the IFAB (rho 0.28, p < 0.001), as well as the stage of behaviour change (rho 0.35, p < 0.001) though not with steps per day. Multivariable analyses were confirmatory.

Conclusion

Perceived barriers and facilitators to physical activity were correlated with physical activity, indicating that targeting patients with high barriers and low facilitators to physical activity could be an effective option to improve physical activity levels.

Effectiveness of web-based and mobile health interventions designed to enhance adherence to physical activity for people with inflammatory arthritis: a systematic review

Objective

The aim of this systematic review was to assess the evidence from randomized controlled trials (RCTs) and cohort studies for the effectiveness of digital interventions designed to enhance adherence to physical activity (PA) for people with inflammatory arthritis and describe the intervention content using established coding criteria.

Methods

Six electronic databases were searched for published and unpublished studies. Independent data extraction and quality assessment (Cochrane risk of bias II or ROBINS-I) were conducted by two reviewers. The primary outcome was self-reported adherence to PA post-intervention. Secondary outcomes included self-reported adherence to PA at other time points, level of PA or engagement with intervention at any follow-up time point. Intervention content was assessed using the Consensus on Exercise Reporting Template and the Behaviour Change Techniques Taxonomy version 1.

Results

From 11 136 citations, four moderate risk of bias studies (three RCTs and one cohort study) including 1160 participants with RA or JIA were identified. Owing to heterogeneity of outcomes, a narrative synthesis was conducted. Only one RCT reported a small between-group difference in adherence to PA [mean difference (95% CI) −0.46 (−0.82, −0.09)] in favour of the intervention. There were no between-group differences in any secondary outcomes. Interventions included between 3 and 11 behaviour change techniques but provided minimal information on exercise prescription.

Conclusion

There is currently limited moderate-quality evidence available to provide confident evaluation of the effect of web-based and mobile health interventions on adherence to PA or level of PA post-intervention in people with inflammatory arthritis.
