To test whether depressive symptoms mediate the effects of activities of daily living (ADLs) on nutritional status of older adults living in long-term care (LTC) facilities in Taiwan.
A cross-sectional study.
Seventy-three community-based LTC facilities in northern Taiwan.
This study sampled 306 adults ranging in age from 65 to 97 years who were free of acute infection or disease and who were able to communicate.
Nutritional status was assessed by the Mini-Nutritional Assessment (MNA) scale and depressive symptoms were assessed by the short form of the Geriatric Depressive Scale (GDS-SF).
MNA scores revealed that 65% of the subjects were at risk for malnutrition (17 to 23.5 points). In addition, depressive symptoms partially mediated the relationship between ADLs and nutritional status, with 10.7% of the effect of depressive symptoms on nutritional status going through the mediator.
Interventions to reduce depressive symptoms among institutionalized older adults should focus on improving nutritional status rather than promoting ADLs, which are believed to be difficult to change.
检验日常生活活动（ADL）对台湾长期护理机构老年人营养状况的影响是否通过抑郁症状产生作用。
横断面研究。
台湾北部的 73 家社区长期护理机构。
本研究共纳入年龄 65 岁至 97 岁、无急性感染或疾病且能够交流的 306 名成年人。
采用 Mini-Nutritional Assessment（MNA）量表评估营养状况，采用老年抑郁量表（GDS-SF）的简短版本评估抑郁症状。
MNA 评分显示，65%的受试者有营养不良风险（17 至 23.5 分）。此外，抑郁症状部分中介了 ADL 和营养状况之间的关系，抑郁症状对营养状况的影响有 10.7%通过中介变量产生作用。
针对机构内老年人的干预措施应侧重于减轻抑郁症状，而不是促进被认为难以改变的 ADL。
