Objective To monitor physical activity during a week among middle-aged and elderly people with type 2 diabetes mellitus (T2DM) for providing evidences to promote scientific physical activity in the people.
Methods We randomly recruited 120 T2DM patients over 40 years old having physical examination at a general hospital in Shenyang city of Liaoning province between March and October 2018. Information on working, commuting, doing housework and having recreational and physical activities during previous one week were collected through a questionnaire survey and all physical activities during the week (at least 10 hours in two workdays and an off day) were monitored using Actigraph GT3X triaxial accelerometer made in the United States for all the participants.
Results Light physical activity was observed among a majority of the participants. The average metabolic equivalent (MET) was 1.37 ± 0.11 and 1.26 ± 0.11 for male and female middle-aged participants; among the elderly participants, the average MET was 1.33 ± 0.08 and 1.20 ± 0.09 for the males and the females. There was a significant gender difference in the average MET for both middle-aged and elderly participants (both P < 0.01).
Conclusion The majority of middle-aged and elderly T2DM patients have light physical activity, indicating a low level of physical activity among this group of T2DM patients.
【摘 要】 目的 通过问卷调查及加速度计监测中老年 2 型糖尿病人群七天的体力活动情况，为中老年糖尿病人群科学开展体力活动等提供理论依据。 方法 于 2018 年 3 — 10 月随机选取在沈阳市第四人民医院参加体检的 40 岁以上的中老年 2 型糖尿病患者 120 例作为研究对象，问卷调查内容包括过去 7 天的工作、交通行程、家务和娱乐休闲体力活动，并使用 Actigraph GT3X（美国）三轴加速度计，监测一周的体力活动，确保每天佩戴 10 小时以上，且至少工作日有 2 天、休息日有 1 天的有效数据。 结果 中老年 2 型糖尿病患者体力活动均以轻体力活动为主；中年2 型糖尿病患者的平均代谢当量：男性（1.37 ± 0.11）METs, 女性（1.26 ± 0.11）METs；老年 2 型糖尿病患者的平均代谢当量：男性（1.33 ± 0.08）METs，女性（1.20 ± 0.09）METs；中年和老年METs 男女间比较差异有统计学意义（ P < 0.01）。 结论 中老年 2 型糖尿病人一周体力活动都轻体力活动为主，2 型糖尿病患者日常体力活动不足。
