Niveau d’activité physique et contrôle ambulatoire de l’hypertension artérielle. Résultats de l’étude pilote « Acti-HTA »

Abstract

While physical activity (PA) is recommended for high blood pressure management, the level of PA practice of hypertensive patients remains unclear. We aimed to assess the association between the level of both PA and blood pressure of individuals consulting in 9 hypertension specialist centres. Eighty-five hypertensive patients were included (59±14years, 61% men, 12% smokers, 29% with diabetes). Following their consultation, they performed home blood pressure measurement (HBPM) over 7days (2 in the morning+2 in the evening), they wrote in a dedicated form their daily activities to estimate the additional caloric expenditure using Acti-MET device (built from International physical Activity Questionnaire [IPAQ]). Thus, patients completed a self-administered questionnaire “score of Dijon” (distinguishing active subjects with a score>20/30, from sedentary<10/30). Subjects with normal HBPM value (<135/85mm Hg) (55% of them) compared to those with high HBPM were older, had a non-significant trend towards higher weekly caloric expenditure (4959±5045kcal/week vs. 4048±4199kcal/week, P=0.3755) and score of Dijon (19.44±5.81 vs. 18.00±4.32, P=0.2094) with a higher proportion of “active” subjects (48.9% vs. 34.2%, P=0.1773). In conclusion, our results demonstrate a “tendency” to a higher level of reported PA for subjects whose hypertension was controlled. This encourages us to continue with a study that would include more subjects, which would assess PA level using an objective method such as wearing an accelerometer sensor.
