Abstract

BACKGROUND

To investigate how changes in sedentary behavior relate to health outcomes, it is important to establish the test-retest reliability of activity monitors in measuring habitual sedentary behavior in people with type 2 diabetes (T2D) as a prerequisite for interpreting this information. Thus, the authors' objective was to examine the test-retest reliability of a common activity monitor (activPAL™) in measuring sedentary behavior and physical activity in people with T2D.

METHODS

Sedentary-time, standing-time, stepping-time, step-count, and sit-to-stand transitions were obtained from two 7-day assessment periods separated by at least 1 week. Test-retest reliability was determined with the intraclass correlation coefficient (ICC) to compare sedentary and activity measures between the 2 time points.

RESULTS

A total of 30 participants with self-reported T2D completed the study (age 65 [6] y, 63% women, body mass index 33.3 [5] kg/m2). High test-retest reliability was found for sedentary-time (ICC = .79; 95% confidence interval [CI], .61-.89) and standing-time (ICC = .74; 95% CI, .53-.87). Very high test-retest reliability was found for stepping-time (ICC = .90; 95% CI, .81-.95), step-count (ICC = .91; 95% CI, .83-.96), and sit-to-stand transitions (ICC = .90; 95% CI, .79-.95).

CONCLUSION

The activPAL™ device showed high to very high test-retest reliability in measuring all tested activity categories in people with T2D.

摘要

背景

为了研究久坐行为的变化与健康结果之间的关系，重要的是要确定活动监测器在测量 2 型糖尿病（T2D）患者习惯性久坐行为方面的重测信度，这是解释这些信息的前提。因此，作者的目的是检验一种常见活动监测器（activPAL™）在测量 T2D 患者久坐行为和身体活动方面的重测信度。

方法

通过至少相隔 1 周的两个 7 天评估期获得久坐时间、站立时间、步数、步数计数和坐站转换。使用组内相关系数（ICC）比较两个时间点的久坐和活动测量值，以确定重测信度。

结果

共有 30 名自我报告患有 T2D 的参与者完成了这项研究（年龄 65 [6] 岁，63%为女性，体重指数 33.3 [5] kg/m2）。久坐时间（ICC =.79；95%置信区间 [CI]，.61-.89）和站立时间（ICC =.74；95% CI，.53-.87）的重测信度很高。步数（ICC =.90；95% CI，.81-.95）、步数计数（ICC =.91；95% CI，.83-.96）和坐站转换（ICC =.90；95% CI，.79-.95）的重测信度非常高。
