We compared the prevalence of participants with and without symptomatic peripheral artery disease (PAD) who met the goals of attaining >7000 and 10 000 steps/d, and we determined whether PAD status was significantly associated with meeting the daily step count goals before and after adjusting for demographic variables, comorbid conditions, and cardiovascular risk factors.
Participants with PAD (n = 396) and without PAD (n = 396) were assessed on their walking for 7 consecutive days with a step activity monitor.
The PAD group took significantly fewer steps/d than the non-PAD control group (6722 ± 3393 vs. 9475 ± 4110 steps/d; P < .001). Only 37.6% and 15.7% of the PAD group attained the goals of walking >7000 and 10 000 steps/d, respectively, whereas 67.9% and 37.4% of the control group attained these goals (P < .001 for each goal). Having PAD was associated with a 62% lower chance of attaining 7000 steps/d than compared with the control group (OR = 0.383; 95% CI, 0.259-0.565; P < .001), and a 55% lower chance of attaining 10 000 steps/d (OR = 0.449; 95% CI, 0.282-0.709; P < .001). Significant covariates (P < .01) included age, current smoking, diabetes, and body mass index.
Participants with symptomatic PAD had a 29% lower daily step count compared with age- and sex-matched controls, and were less likely to attain the 7000 and 10 000 steps/d goals. Additionally, participants who were least likely to meet the 7000 and 10 000 daily step count recommendations included those who were older, currently smoked, had diabetes, and had higher body mass index.
我们比较了患有症状性外周动脉疾病（PAD）和无 PAD 的参与者达到 >7000 和 10000 步/天目标的比例，并在调整人口统计学变量、合并症和心血管危险因素后，确定 PAD 状态与达到每日步数目标是否显著相关。
用计步器评估 396 名 PAD 患者和 396 名无 PAD 对照者连续 7 天的步行情况。
PAD 组每天的步数明显少于非 PAD 对照组（6722±3393 步/天 vs. 9475±4110 步/天；P<.001）。只有 37.6%和 15.7%的 PAD 组分别达到了行走 >7000 和 10000 步/天的目标，而对照组的这一比例分别为 67.9%和 37.4%（每个目标的 P<.001）。与对照组相比，PAD 患者达到 7000 步/天目标的可能性低 62%（OR=0.383；95%CI，0.259-0.565；P<.001），达到 10000 步/天目标的可能性低 55%（OR=0.449；95%CI，0.282-0.709；P<.001）。显著的协变量（P<.01）包括年龄、当前吸烟状况、糖尿病和体重指数。
与年龄和性别匹配的对照组相比，有症状性 PAD 的参与者每日步数少 29%，达到 7000 和 10000 步/天目标的可能性也较低。此外，最不可能达到 7000 和 10000 步/天日常推荐量的参与者包括年龄较大、当前吸烟、患有糖尿病和体重指数较高的人。
