노인의 고혈압과 웨어러블 디바이스로 측정된 신체 활동량의 연관성

Abstract

Purpose: Studies examining the association between hypertension and physical activity according to the activity intensity of older adults, as measured by wearable devices, are limited. In this study, we investigated the association between hypertension and physical activity using data collected by wearable devices in adults aged ≥ 65 years.
 Methods: Fifty-two adults were recruited and divided into the hypertension (systolic blood pressure ≥ 140 mmHg, diastolic blood pressure ≥ 80 mmHg, or the use of antihypertensive medications) and control groups. Wearable devices were used to provide an objective measure of the study participants’ physical activity. The physical activity data collected were analyzed according to the daily average time of vigorous, moderate, and light activities and sedentary behavior. The daily amount of time allotted for physical activity according to activity intensity was compared between the hypertension and control groups.
 Results: Older adults with hypertension spent significantly less time participating in vigorous and moderate activities and exhibited increased sedentary behavior than those in the control group (p<.05). Additionally, older adults who participated in vigorous activities were less likely to have hypertension (odds ratio [OR]=.923, 95% confidence interval [CI]=.858-.994; adjusted OR=.919, 95% CI=.854-.989).
 Conclusion: Thus, the results of this study demonstrated an association between hypertension prevalence and the amount of physical activity in older adults using data obtained from wearable devices. Future studies are needed to investigate the effects of changing the physical activity patterns on hypertension, such as increasing the amount of moderate or vigorous activities and/or decreasing sedentary behavior.
