Patients with chronic diseases: physical activity level and self-perception ; Niveau et perception de l’activité physique de patients souffrant de maladies chroniques : étude transversale au sein de la cohorte française ComPaRe

Background: despite the many health benefits of physical activity (PA), sedentary behavior remains prevalent among people and most PA promotion programs in primary care are not effective. We hypothesize that many patients do not have an accurate perception of their PA level, which is a major driver of behaviour change and engagement. Objective: to assess the physical activity level of chronically ill patients by the GPAQ questionnaire and their perception of reaching WHO guidelines regarding PA level. Methods: we conducted a 2022 cross-sectional study nested within the French national «Community of Patients for Research» (ComPaRe) e-cohort of adult patients with chronic conditions. We included active members (i.e., last login in last 18 months) with a stratified random sampling. Eligible patients were asked to complete a questionnaire including the Global Physical Activity Questionnaire (GPAQ) and a question on their perception of reaching WHO guidelines. Concordance was assessed by calculating Cohen’s kappa coefficient. Results: we included 629 patients (participation rate: 65.04%). Median age was 57 [46.0-65.4] years, women were 348 (55.3%). A total of 55 (8,6%) participants were not able to estimate their PA level, and 171 (29.8%) participants misperceived their PA (Cohen’s kappa coefficient of 0.41[0.34-0.48]), with 18.8% of overestimation among the 260 (45.3%) participants categorized as inactive by the GPAQ. Conclusions: moderate perception of PA level by patients should be taken into account by health professionals to allow PA counselling to be targeted to the right individuals as part of a patient personalized care approach and minimally disruptive medicine. ; INTRODUCTION : malgré les nombreux bénéfices de l'activité physique (AP) pour la santé, l'inactivité reste très répandue et la plupart des programmes de promotion de l'AP dans les soins primaires ne sont pas vraiment efficaces. Nous émettons l'hypothèse que de nombreux patients ont une perception erronée de leur niveau d'AP, qui est un facteur ...
