Few studies have described ambulatory activity in free-living individuals with type 2 diabetes mellitus (T2DM) using motion sensors, and none included a control group. For this reason, our study compared the physical-activity levels of outpatients with T2DM with subjects without diabetes, and examined the relationship between body mass index (BMI) and physical-activity parameters.
Physical-activity levels in 70 outpatients with T2DM and 30 age-, gender- and employment-matched individuals without diabetes were measured using the SenseWear Armband™, a monitoring device validated against doubly labelled water, to assess total energy expenditure. Patients wore the SenseWear Armband™ on their right arm continuously every day for 1 week.
Total energy expenditure (<300 kcal/day), number of steps (<1500/day), physical-activity duration (<130 min/day) and active energy expenditure/day (<300 kcal) were all significantly lower (P<0.05) in patients with T2DM. These measures were inversely correlated with BMI, and remained significant after adjusting for age, gender, employment status and the presence of diabetes.
Outpatients with T2DM have lower physical-activity levels than their matched controls, a characteristic that is related to their higher BMI.
使用运动传感器描述 2 型糖尿病（T2DM）患者的日常活动情况的研究较少，且没有研究纳入对照组。因此，我们的研究比较了 T2DM 门诊患者与无糖尿病患者的体力活动水平，并探讨了体重指数（BMI）与体力活动参数之间的关系。
使用 SenseWear Armband™（一种经过双标水验证的监测设备）测量 70 例 T2DM 门诊患者和 30 名年龄、性别和就业情况相匹配的无糖尿病个体的体力活动水平，以评估总能量消耗。患者每天连续在右臂佩戴 SenseWear Armband™ 一周。
T2DM 患者的总能量消耗（<300 kcal/天）、步数（<1500/天）、体力活动时间（<130 分钟/天）和活跃能量消耗/天（<300 kcal）均显著降低（P<0.05）。这些措施与 BMI 呈负相关，且在调整年龄、性别、就业状况和糖尿病存在后仍然显著。
T2DM 门诊患者的体力活动水平低于其匹配对照组，这一特征与他们更高的 BMI 有关。
