Physical activity (PA) is important in managing Type 2 Diabetes Mellitus (T2DM). This study aimed to determine 1) the number of daily steps taken by older people with T2DM, 2) if T2DM is associated with taking fewer steps per day and less likelihood of meeting PA guidelines, and 3) whether these associations are modified by age or gender.
PA was obtained by pedometer from 2 cohorts of older adults with and without T2DM. Multivariable regression was used to determine associations between T2DM, mean steps per day and meeting a guideline equivalent (7 100 steps per day).
There were 293 participants with T2DM (mean age 67.6 ± 6.8 years) and 336 without T2DM (mean age 72.1 ± 7.1 years). In women, T2DM was associated with fewer mean steps per day (β = -1306.4; 95% CI -2052.5, -560.3; P = .001) and not meeting the PA guidelines (OR 0.51; 95% CI 0.28, 0.92; P = .03). Associations were not significant in men (P > .05). Only 29.7% of those with T2DM and 33.3% of those without T2DM met PA guidelines.
Greater focus is needed on how to maintain and increase PA in older age with particular focus on women with T2DM.
身体活动（PA）对于管理 2 型糖尿病（T2DM）很重要。本研究旨在确定：1）患有 T2DM 的老年人每天的步数；2）T2DM 是否与每天的步数减少和更不可能达到 PA 指南相关；3）这些关联是否会被年龄或性别所改变。
通过计步器从有和没有 T2DM 的两组老年人中获取 PA 数据。多变量回归用于确定 T2DM、每天的平均步数和达到指南标准（每天 7100 步）之间的关联。
共有 293 名患有 T2DM（平均年龄 67.6 ± 6.8 岁）和 336 名无 T2DM（平均年龄 72.1 ± 7.1 岁）的参与者。在女性中，T2DM 与每天的平均步数减少（β=-1306.4；95%CI -2052.5，-560.3；P=0.001）和不符合 PA 指南相关（OR 0.51；95%CI 0.28，0.92；P=0.03）。在男性中，这些关联不显著（P＞0.05）。仅有 29.7%的患有 T2DM 的人和 33.3%的没有 T2DM 的人符合 PA 指南。
需要更加关注如何在老年时保持和增加 PA，特别是针对患有 T2DM 的女性。
