Brief Summary:

Background: Patients with inflammatory arthritis (IA), such as spondyloarthritis (axSpA), rheumatoid arthritis (RA) or psoriatic arthritis (PsA) are more prone to physical inactivity but derive specific benefits from regular physical activity. Barriers and facilitators to physical activity (B&F-PA) are key elements and knowledge of their correlation to physical activity is essential for developing interventions to promote physical activity that have a greater likelihood of success.

Objectives: primary objective will be to measure the correlation of these B&F-PA to physical activity collected through apps. Secondary objective will be to (I) to quantify physical activity collected through apps in IA patients and (II) to observe the link between physical activity, B&F to physical activity and adherence to treatment.

Patients and methods: This is an international, multicentric, cross-sectional study.

Patients: From the first of September to the first of February 2020, all patients with definite axSpA, RA or PsA, aged above 18 and able to walk, who have a mobile phone compatible with apps that can track steps, who agree to participate and give his oral informed consent and with ability to read and write in the language of the participating country, seen in outpatient visits in the participating centers, will be asked to participate. The planed inclusion was 200 participants.

Data collection: clinical data and information about physical activity and B&F-PA will be entered by rheumatologists during or electronically by patients at the same time point.

Questionnaire for B&F-PA: a patient reported questionnaire was recently developed for this study in 2019 based on a systematic review to identify the main B&F-PA. A list of questions was generated from the systematic review reviewed and tested for face validity by 11 experts and confronted to 20 patients with IA through a cognitive debriefing.

Physical activity: Physical activity will be measured objectively during the last 7 days by apps already installed by default on the mobile phone of participants and subjectively with the International Physical Activity Questionnaire short version (IPAQ-S).

Other outcomes: Stage of exercise behavior change and adherence to treatment will also be collected.

Planned analyses: Perceived B&F-PA will be described using frequencies. A score will be calculated for each participant representing the limitations or facilities to perform physical activity.

Analysis of the physical activity: The distribution of mean number of steps will be assessed visually for outliers. Univariate analysis will be completed between mean number of steps and gender, age, disease and stages of change. Correlation between mean number of steps and IPAQ-S score will be calculated.

Link between physical activity and barriers and facilitators: The link between B&F questionnaire score and mean number of steps will be tested using linear regression. Then multivariate regression including demographic variables, psychological status and disease characteristics will be performed.

Outcomes of the study: The expected outcomes of the ImBAIA study are a better understanding of B&F to physical activity in patients with IA and their impact to limit or to favor physical activity. We also expect to observe the level of physical activity of an IA population objectively measured with apps. Finally, a validation was expected to use questionnaire of B&F.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Sampling Method:   Probability Sample
Study Population
Outpatients from secondary and tertiary care hospitals in France and in the United Kingdom will be invited to participate. Over the 5 months recruitment period, all patients with definite axSpA, RA or PsA who satisfy the inclusion criteria, seen in outpatient visits in the participating centers by one of the investigators, will be asked to participate. We plan to include 200 participants (based on a sample size calculation explained in statistical analysis part), 10-20 patients in each center, with a maximum of 30 patients per center and a competitive recruitment. We will aim for a minimum of 50 patients per disease group. After including of 50% of the population we will reorient inclusion if needed. Data will be collected at a single moment, during a usual visit.

Inclusion Criteria:

  • aged above 18 and able to walk
  • Definite IA confirmed by the rheumatologist and based on usual criteria: axSpA (referring to the Assessment of Spondyloarthritis international Society classification criteria (51)), RA (referring to the international classification criteria of RA (52)) or PsA (referring to the ClASsification of Psoriatic Arthritis (CASPAR) criteria (53)), with no restriction for co-morbidities,
  • have a mobile phone compatible with apps that can track steps,
  • agree to participate and give informed consent,
  • ability to read and write in the language of participating country.

Exclusion Criteria:

Patients who don't speak or read the local language or are not comfortable filling in a Case Report Form in the local language or who don't have a mobile phone compatible with health apps.
