该研究的目的是检查患有间歇性跛行的外周动脉疾病患者的踝臂指数（ABI）和休闲时间体力活动（LTPA）之间的关系。患者包括 342 名久坐的男性和女性，年龄在 45 岁至 85 岁之间，患有间歇性跛行，经静息 ABI 低于 0.90 证实。患者被分为低 ABI 组（ABI < 0.50；n = 84）、中 ABI 组（ABI = 0.50 至 0.69；n = 164）或高 ABI 组（ABI = 0.70 至 0.89；n = 94）。明尼苏达州 LTPA 问卷用于评估身体活动模式，跑步机测试、6 分钟步行测试和步行障碍问卷用于测量步行功能。在高 ABI（180 +/- 131 kcal/天；平均 SID）、中 ABI（138 +/- 127 kcal/天）和低 ABI（110 +/- 89 kcal/天）组中观察到总 LTPA 逐渐下降（p = 0.030）。在三个相应的 ABI 组中，观察到中等强度 (p = 0.016) 和高强度 (p = 0.009) 的 LTPA 消耗以及 LTPA 平均强度 (p = 0.024) 逐渐减少。在调整跑步机测试期间绝对跛行距离和 6 分钟步行距离的组间差异后，LTPA 测量值的组间差异不再存在 (p > 0.05)。间歇性跛行患者每日总 LTPA 下降且 ABI 逐渐降低，这是因为他们减少了需要中强度和高强度的体力活动的参与。此外，LTPA 测量值的组间差异可以通过行走功能的差异来解释。
The purpose of the study was to examine the relationship between ankle-brachial index (ABI) and leisure-time physical activity (LTPA) in patients with peripheral arterial disease limited by intermittent claudication. Patients included 342 sedentary men and women between the ages of 45 and 85 with intermittent claudication confirmed by a resting ABI of less than 0.90. Patients were categorized into either a low ABI group (ABI < 0.50; n = 84), a middle ABI group (ABI = 0.50 to 0.69; n = 164), or a high ABI group (ABI = 0.70 to 0,89; n = 94). The Minnesota LTPA questionnaire was used to estimate physical activity patterns, and a treadmill test, 6-minute walk test, and Walking Impairment Questionnaire were used to measure ambulatory function. A progressive decrease (p = 0.030) in the total LTPA was observed among the high ABI (180 +/- 131 kcal/day; mean SID), middle ABI (138 +/- 127 kcal/day), and low ABI (110 +/- 89 kcal/day) groups. Progressive decrements in LTPA spent at moderate intensity (p = 0.016) and high intensity (p = 0.009), as well as the mean intensity of LTPA (p = 0.024) were observed among the three respective ABI groups. Group differences in the LTPA measurements were no longer present (p > 0.05) after adjusting for group differences in the absolute claudication distance during a treadmill test, and the 6-minute walk distance. The decline in total daily LTPA with progressively lower ABI in patients with intermittent claudication was due to their decreased participation in physical activities requiring moderate and high intensities. In addition, group differences in the LTPA measurements were explained by differences in ambulatory function.
