Maintaining independence in instrumental activities of daily living (IADL) is crucial for older adults. This study explored the association between cognitive and functional performance in general and in single IADL domains. Also, risk factors for developing IADL impairment were assessed.
Here, 3,215 patients aged 75-98 years were included. Data were collected during home visits.
Cognitive functioning was associated with IADL both cross-sectionally and longitudinally. Regarding the single IADL domains cross-sectionally, executive functioning was especially associated with shopping, while episodic memory was associated with responsibility for own medication.
Reduced performance in neuropsychological tests is associated with a greater risk of current and subsequent functional impairment.
维持日常生活活动工具性能力（IADL）的独立性对老年人至关重要。本研究探讨了认知和功能表现的一般关联，以及在单一 IADL 领域的关联。此外，还评估了导致 IADL 受损的风险因素。
本研究纳入了 3215 名年龄在 75-98 岁的患者。数据是通过家访收集的。
认知功能与 IADL 既有横断面关系，也有纵向关系。关于单个 IADL 领域的横断面关系，执行功能与购物特别相关，而情景记忆与负责自己的药物相关。
神经心理学测试表现下降与当前和随后的功能障碍风险增加相关。
