Correlates of physical activity in adults with spondyloarthritis and rheumatoid arthritis: a systematic review

Physical activity (PA) is a primary non-pharmacological treatment option for those living with rheumatoid arthritis (RA) and spondyloarthritis (SpA). The aim of this systematic literature review was to summarize and present an updated synthesis of the factors associated with PA in the RA and SpA populations. A tailored search of PubMed (inc. Medline), Web of Science, Embase, APA PsycNET, and Scopus was conducted for research published between 2004 and June 2019. Methodological quality was assessed using The National Institutes of Health (NIH) Quality Assessment Tools for Observational Cohort and Cross-sectional Studies, Case–Control Studies, and Controlled Intervention Studies. Forty RA and eleven SpA articles met the inclusion criteria. Methodological quality was generally fair to good, with two RA studies rated as poor. Correlates are discussed in the sociodemographic, physical, psychological, social, and environmental categories. Environmental factors were not measured in any RA study. In individuals living with RA, consistent positive associations were found between PA and high-density lipoprotein, self-efficacy, and motivation. Consistent negative associations were found for functional disability and fatigue. In individuals with SpA, consistent positive associations were found between PA and quality of life, and consistent negative associations with functional disability. Physical and psychological factors are most consistently related with PA parameters in those living with RA and SpA. Many variables were inconsistently studied and showed indeterminant associations. Studies with prospective designs are needed to further understand the factors associated with PA in these populations, especially in those living with SpA.

Physical activity and attitudes and perceptions towards physical activity in patients with spondyloarthritis: A systematic review

OBJECTIVE

To review systematically and synthesize qualitatively the literature about physical activity and perceptions and attitudes towards physical activity/exercise among patients with spondyloarthritis (SpA).

METHODS

PubMed, CINAHL and Scopus and reference lists were searched for quantitative and qualitative studies reporting on beliefs towards exercise in patients with SpA. Searches were limited to studies published from January 2000 through December 2018. The PRISMA guidelines were followed. Systematic searches identified 128 publications which underwent a title, abstract, or full-text review. Studies were excluded if articles were not in English or did not include original data. We summarized the methodologic quality using modified criteria for quantitative and qualitative studies.

RESULTS

Eight quantitative and three qualitative studies met eligibility criteria, with variable study quality. Based on self-reported data, 50% to 68% of patients with SpA met physical activity recommendations with walking, swimming/pool exercise, and cycling the most common forms reported. Intrinsic factors such as motivation and improvement in symptoms and health were commonly reported as facilitators associated with physical activity/exercise. Barriers included lack of time, fatigue, and symptoms such as pain.

CONCLUSION

One third to one half of patients with SpA do not meet physical activity recommendations. Given the potential for regular physical activity to reduce symptom burden in this patient population and the recommendation for regular physical activity as part of the management of these patients, more rigorous studies of physical activity behaviors and attitudes will be useful to inform interventions and promote exercise among individuals with SpA.

Differences in physical activity patterns in patients with spondylarthritis

OBJECTIVE

To study patient-reported physical activity in patients with spondylarthritis (SpA) and possible differences in physical activity patterns between the SpA subtypes and sexes.

METHODS

In 2009, a questionnaire including inquiries concerning physical activity was sent to patients with a SpA diagnosis (n = 3,711). The World Health Organization (WHO) global recommendations of physical activity for health requiring 150 minutes of moderate-intensity physical activity (MI-PA) or 75 minutes of vigorous-intensity physical activity (VI-PA) per week were used as recommended levels. Standardized risk ratios (RRs) were calculated by using physical activity data from the Swedish population. The association within the SpA group between sex, age, disease-related variables, anxiety, and depression and meeting recommended levels of MI-PA and VI-PA (dependent variables) was studied with multivariate analysis.

RESULTS

A total of 2,167 patients with SpA (48% men, mean ± SD age 55 ± 14 years) responded to the questionnaire. Sixty-eight percent of the patients met the WHO recommendations, more frequently in women than in men (70% versus 66%). The recommendations were more often met in the SpA group (RR 1.09, 95% confidence interval [95% CI] 1.04-1.15) compared with the Swedish population. There was a tendency for young women to meet the WHO recommendations less often than the Swedish population (RR 0.94, 95% CI 0.63-1.25). Different factors were found to influence whether the patients were exercising with a moderate or vigorous intensity.

CONCLUSION

Seven of 10 patients with SpA met the WHO recommendations of physical activity for health, but we found sex and disease subtype differences. This information can be useful in clinical practice when coaching patients to have a healthier lifestyle.
