Abstract

This study explored the effect of weight change on successful aging in older adults. A total of 1865 adults (≥65 years) were divided into the weight gain group (weight gain ≥5 %), the weight loss group (weight loss ≥5 %), and the weight stable group (weight change <5 %) according to weight changes over 4 years. Results showed that compared to the stable weight, the weight loss is associated with a lower rate of successful aging (OR=0.64, 95 % CI: 0.49-0.83), and the association was found greater in women (OR=0.61, 95 % CI: 0.43-0.86) and young-old adults (OR=0.66, 95 % CI: 0.41-0.88) than their counterparts. However, no significant association was found between weight gain and successful aging. The findings suggest that weight loss rather than weight gain in older adults has a detrimental impact on successful aging, and this detrimental impact is greater in women and young-old adults.

摘要

本研究探讨了体重变化对老年人成功老龄化的影响。根据4年期间的体重变化，共1865名成年人（≥65岁）被分为体重增加组（体重增加≥5%）、体重减轻组（体重减轻≥5%）和体重稳定组（体重变化<5%）。结果显示，与体重稳定相比，体重减轻与较低的成功老龄化率相关（OR=0.64，95%CI：0.49-0.83），并且在女性（OR=0.61，95%CI：0.43-0.86）和年轻老年人（OR=0.66，95%CI：0.41-0.88）中这种关联比其对应人群更强。然而，未发现体重增加与成功老龄化之间存在显著关联。研究结果表明，老年人的体重减轻而非体重增加对成功老龄化有不利影响，且这种不利影响在女性和年轻老年人中更大。
