To determine predictive validity for cut points of the Timed Up & Go (TUG) test and life-space assessment (LSA) on decline in instrumental activities of daily living (IADLs) among older adults.
Cross-sectional and 1-year follow-up study.
Preventive health care services.
In a cross-sectional study, 2404 older adults (65-100 y) were recruited to determine cut points for the TUG and LSA for IADLs limitation. For longitudinal analysis, 436 older adults (65-100 y) were followed over 1 year to explore the validity of a classification model using the cut points to predict incident IADLs decline.
Not applicable.
The TUG, LSA, and Tokyo Metropolitan Institute of Gerontology index of IADLs measurement.
The cut points associated with IADLs limitations for the TUG and LSA were 12 seconds and 56 points, respectively. Participants were classified into fast/high (most able; TUG <12 and LSA >56), fast/low, slow/high, and slow/low (vulnerable; TUG > or =12 and LSA < or =56) groups; there were 813 (34%), 385 (16%), 246 (10%), and 960 (40%) participants in each group, respectively. The proportions of participants with IADLs limitation in the most able, fast/low, slow/high, and vulnerable groups were 19%, 64%, 61%, and 89%, respectively. The vulnerable group included significantly more participants with IADLs limitation than any other group (P<.001). Compared with a most able group, the odds ratios of IADLs decline for the fast/low and vulnerable groups were 2.52 (95% confidence interval 1.15-5.53, P<.05) and 2.87 (95% confidence interval 1.38-5.96, P<.01), respectively.
The combination of TUG and LSA identifies persons with future IADLs decline and has the potential to be used by community health care services to target individualized interventions.
确定计时起立行走测试（TUG）和生活空间评估（LSA）的切点对老年人日常活动能力下降（IADLs）的预测效度。
横断面和 1 年随访研究。
预防保健服务。
在一项横断面研究中，招募了 2404 名老年人（65-100 岁）以确定 TUG 和 LSA 对 IADLs 限制的切点。对于纵向分析，对 436 名老年人（65-100 岁）进行了 1 年随访，以探索使用切点对事件性 IADLs 下降进行分类模型的有效性。
不适用。
TUG、LSA 和东京都立老年研究所 IADLs 测量指数。
TUG 和 LSA 与 IADLs 限制相关的切点分别为 12 秒和 56 分。参与者被分为快速/高（最有能力；TUG<12 且 LSA>56）、快速/低、缓慢/高和缓慢/低（脆弱；TUG≥12 且 LSA≤56）组；每组分别有 813 名（34%）、385 名（16%）、246 名（10%）和 960 名（40%）参与者。最有能力、快速/低、缓慢/高和脆弱组中 IADLs 受限的参与者比例分别为 19%、64%、61%和 89%。脆弱组中 IADLs 受限的参与者明显多于其他任何一组（P<.001）。与最有能力组相比，快速/低和脆弱组 IADLs 下降的优势比分别为 2.52（95%置信区间 1.15-5.53，P<.05）和 2.87（95%置信区间 1.38-5.96，P<.01）。
TUG 和 LSA 的结合可以识别出未来 IADLs 下降的患者，有可能被社区保健服务用于针对个体化干预。
