Évaluation de l’effet d’une prescription écrite sur le niveau d’activité physique à 3 mois d’une population présentant des facteurs de risque cardio-vasculaire en médecine générale. Étude réalisée de janvier à octobre 2017

Abstract : Objective: to measure, in primary care with a validated physical activity questionnaire, the change in physical activity in patients at risk for cardiovascular events, on a period of three months. To study the factors associated to change in physical activity after prescription. Methods: quantitative interventional study by follow-up of a cohort. Patients suffering from high blood pressure and/or hyperlipidemia and/or non insulin dependent diabetes were enrolled by some general practitioners who gave them a written prescription for physical activity. Their level of physical activity was assessed at the time of inclusion, and again after one and three months of follow-up with the IPAQ short version questionnaire. The mean IPAQ scores at 1 and 3 month follow-up were compared to the initial score with a Student t-test. We did a bivariate analysis to determine which factors were associated to change in physical activity after prescription. Results: physical activity did not increase significantly, neither at 1 month follow-up (median +566 MET-min/week (IQR 25-75 : -921 – 1640), p = 0.12), nor at 3 month follow-up (+436 METmin/week (IQR 25-75 : -789 – 1960), p = 0.073) on the whole studied population. Nevertheless, it did increase significantly in patients assessed at the time of inclusion as « inactive » (+833 METmin/week, IQR 25-75 : 421 – 1897, p = 0.007) or « moderately active » (+482 MET-min/week (IQR 25-75 : -314 – 2674, p = 0.005). Conclusions: a written prescription for physical activity improves the level of physical activity of initially inactive or moderately active patients after 3 months of follow-up. To create a simple tool aimed at spotting the already highly active patients would help optimize the prescription of physical activity in primary care.
