摘要

研究背景本研究的目的是评估加速度计在预测生活方式干预期间体重(BW)变化方面的作用,并找出运动或总体体力活动是否与胰岛素敏感性和身体成分的变化有关:共招募了 49 名超重(体重指数[BMI] ≥ 23 kg/m(2))的女性糖尿病患者,她们在接受生活方式干预的同时,使用加速度计监测体重、总能量消耗(TEE)和体力活动能量消耗(PAEE),并在基线期和 12 周内每两周使用三天饮食记录监测能量摄入(EI)。我们使用生物阻抗分析评估身体成分,并将实际体重变化与预测体重变化进行比较,预测体重变化是根据 EI 与 TEE 之间的能量赤字(ED)计算得出的(ED = EI-TEE):平均年龄为 57.2 岁,糖尿病病程为 8.0 年,体重指数为 27.8 kg/m(2)。基线时,EI 和 TEE 没有明显差异。12 周内,ED 为 474.0 千卡-天(-1),与体重变化(-3.1 千克)显著相关(r = 0.725,P < 0.001)。然而,实际体重变化比预测体重变化低 50%。TEE 和 PAEE 与 K(ITT)(分别为 r = 0.334,P = 0.019;r = 0.358,P = 0.012)、体重指数(分别为 r = -0.395,P = 0.005;r = -0.347,P = 0.015, respectively)和脂肪量(r = -0.383, P = 0.007; r = -0.395, P = 0.005, respectively),但只有 TEE 与无脂肪量变化相关(r = -0.314, P = 0.030):加速度计似乎是在自由生活条件下测量短期和长期 TEE 的有用工具。

The usefulness of an accelerometer for monitoring total energy expenditure and its clinical application for predicting body weight changes in type 2 diabetic korean women.

Background: The purpose of this study was to evaluate the usefulness of an accelerometer in predicting body weight (BW) change during a lifestyle intervention and to find out whether exercise or overall physical activity is associated with change in insulin sensitivity and body composition.

Methods: A total of 49 overweight (body mass index [BMI] ≥ 23 kg/m(2)) women with diabetes were enrolled and performed lifestyle intervention while monitoring BW, total energy expenditure (TEE) and physical activity energy expenditure (PAEE) using an accelerometer, and energy intake (EI) using a three-day dietary record at baseline and every 2 weeks for 12 weeks. We assessed body composition using bioimpedance analysis and compared the actual BW change to the predicted BW change, which was calculated from the energy deficit (ED) between EI and TEE (ED = EI-TEE).

Results: Mean age was 57.2 years, duration of diabetes was 8.0 years, and BMI was 27.8 kg/m(2). There was no significant difference between EI and TEE at baseline. For 12 weeks, the ED was 474.0 kcal·day(-1), which was significantly correlated with BW change (-3.1 kg) (r = 0.725, P < 0.001). However, the actual BW change was 50% lower than the predicted BW change. Both TEE and PAEE correlated with change in K(ITT) (r = 0.334, P = 0.019; r = 0.358, P = 0.012, respectively), BMI (r = -0.395, P = 0.005; r = -0.347, P = 0.015, respectively), and fat mass (r = -0.383, P = 0.007; r = -0.395, P = 0.005, respectively), but only TEE correlated with fat free mass change (r = -0.314, P = 0.030).

Conclusion: The accelerometer appears to be a useful tool for measuring TEE under free-living conditions for both short- and long-term periods.
