本研究的目的是调查在 2 型糖尿病的物理干预研究中，计步器的使用是否可以增加步行次数和/或增强有益结果。 70 名 2 型糖尿病患者被随机分为计步器组和非计步器组（P 组和非 P 组）。所有参与者在基线访视（VI）、1个月后、3个月后和6个月后均由护士看望，然后鼓励他们增加步行。 P 组的受试者还每月记录两次计步器步数，每次 3 天，持续 6 个月。 VI后和6个月时回访，测量有氧能力(VO2peak)；受试者报告了感知的身体健康和活动。二十二名受试者没有完成研究（中途退出）。中途退出者的 V1 摄氧量峰值低于完成研究的受试者（完成者）(P = .003)。在 P 组中，从第 1 个月到第 6 个月，每天的步数没有增加 (P = .65)。总的来说，完成者的体重 (P = .005)、血红蛋白 A(1c) (P = .034)、空腹血糖 (P = .033)、甘油三酯 (P = .002) 和舒张压 (P = .048) 有所下降，高密度脂蛋白胆固醇 (P < .001) 有所增加，P 组之间没有差异这些变量的非 P 组（所有 P 值 >.38）。身体和精神状态的感知改善与 VO2peak 的改善相关（分别为 r = 0.45，P = .008 和 r = 0.38，P = .03；n = 34）。我们的结论是，计步器的使用并没有增加步行量或增强有益的代谢结果。辍学者的有氧能力较低表明最需要体育锻炼的人对锻炼计划的依从性最低。 (C) 2008 Elsevier Inc. 保留所有权利。
The aim of the present study was to investigate whether the use of pedometer increases walking and/or enhances beneficial outcomes in a physical intervention study in type 2 diabetes mellitus. Seventy persons with type 2 diabetes mellitus were randomized to a pedometer and a nonpedometer group (P and non-P groups). All participants were seen by a nurse at a baseline visit (VI), after I month, after 3 months, and after 6 months and were then encouraged to increase walking. Subjects in the P group additionally registered pedometer steps 3 days twice per month for 6 months. After VI and the visit at 6 months, aerobic capacity VO2peak) was measured; and subjects reported perceived physical fitness and activity. Twenty-two subjects did not complete the study (dropouts). The VO2peak at V1 was lower in dropouts than in subjects who completed the study (completers) (P = .003). In the P group, the number of steps per day did not increase from month 1 to month 6 (P = .65). In completers, taken together, there was a decrease in body weight (P = .005), hemoglobin A(1c) (P = .034), fasting blood glucose (P = .033), triglycerides (P = .002), and diastolic blood pressure (P = .048) and an increase in high-density lipoprotein cholesterol (P < .001), with no difference between the P group and non-P group for these variables (all P values >.38). Perceived improvement in physical and mental state correlated with improvement in VO2peak (r = 0.45, P = .008 and r = 0.38, P = .03, respectively; n = 34). We conclude that the use of pedometer did not increase walking or enhance beneficial metabolic outcomes. The low aerobic capacity in dropouts indicates that persons most needy of physical exercise are the least compliant in exercise programs. (C) 2008 Elsevier Inc. All rights reserved.
