本研究的目的是比较短版本和长版本的内在能力指数，并测试它们与老年人相关健康结果的横断面关联。设计对FraDySMex研究的基线数据进行横断面分析。参与者543名居住在墨西哥城2个城市的50岁及以上的社区居民，其中435人有完整的感兴趣变量数据。方法采用主成分分析法，获得内蕴容量指标。分别对脆性、IADL和ADL指标进行性能测试。结果短版和长版IC指数均能较好地评价功能状态。使用步态仪测量的相位角、握力和步态速度等生物特征变量可改善相对于IADL残疾的指标表现（Lawton），但对其他评估结果没有改善。结论所测试的长、短版本的内在能力指数均能根据老年人的功能状态对其进行分类，并与相关的健康结果相关。
Objectives The aim of this study was to compare a short and a long version of an intrinsic capacity index and test their cross-sectional association with relevant health outcomes in older adults. Design Cross-sectional analysis of the baseline data of the FraDySMex study. Participants 543 community-dwelling adults aged 50 years and older living in 2 municipalities in Mexico City, from which 435 had complete data on the variables of interest. Methods The intrinsic capacity indices were obtained using principal components analysis. The performance of the indices was tested respective to frailty, IADL and ADL. Results The short and long versions of the IC index performed well for assessing functional status. Using biometrical variables like the phase angle, grip strength and gait speed measured by the GAIT rite improved the index performance vis a vis IADL disability (Lawton), but not to the other evaluated outcomes. Conclusions Both the long and short versions of the intrinsic capacity indices tested were able to classify older adults according to their functional status and were associated with relevant health outcomes.
