The authors tested the efficacy of the "I-STAND" intervention for reducing sitting time, a novel and potentially health-promoting approach, in older adults with obesity.
The authors recruited 60 people (mean age = 68 ± 4.9 years, 68% female, 86% White; mean body mass index = 35.4). The participants were randomized to receive the I-STAND sitting reduction intervention (n = 29) or healthy living control group (n = 31) for 12 weeks. At baseline and at 12 weeks, the participants wore activPAL devices to assess sitting time (primary outcome). Secondary outcomes included fasting glucose, blood pressure, and weight. Linear regression models assessed between-group differences in the outcomes.
The I-STAND participants significantly reduced their sitting time compared with the controls (-58 min per day; 95% confidence interval [-100.3, -15.6]; p = .007). There were no statistically significant changes in the secondary outcomes.
I-STAND was efficacious in reducing sitting time, but not in changing health outcomes in older adults with obesity.
作者测试了“I-STAND”干预措施在减少肥胖老年人久坐时间方面的效果，这是一种新颖且可能促进健康的方法。
作者招募了60人（平均年龄=68±4.9岁，68%为女性，86%为白人；平均体重指数=35.4）。参与者被随机分为接受I-STAND久坐减少干预组（n=29）或健康生活对照组（n=31），为期12周。在基线和12周时，参与者佩戴activPAL设备以评估久坐时间（主要结果）。次要结果包括空腹血糖、血压和体重。线性回归模型评估了两组在结果方面的差异。
与对照组相比，I-STAND参与者的久坐时间显著减少（每天减少58分钟；95%置信区间[-100.3，-15.6]；p=0.007）。次要结果没有统计学上的显著变化。
I-STAND在减少肥胖老年人久坐时间方面有效，但在改变健康结果方面无效。
