本研究的目的是评估13年来一般认知和功能能力的交叉滞后面板模型。目的是确定一般认知能力是否预测或先于功能衰退，而功能能力是否预测认知衰退。样本包括来自Kuakini檀香山-亚洲老龄化研究项目的3508名男性（基线年龄在71-93岁之间），他们接受了全球认知测试和功能能力评估的反复测试。教育和年龄作为协变量。对交叉滞后模型进行检验，评估稳定性和交叉滞后的平稳性。整个模型与数据吻合得很好。随着时间的推移，认知得分比功能能力得分具有更好的稳定性，并且预测功能能力比功能能力预测认知得分更强。所有交叉滞后的强度随着时间的推移而增加。这些纵向数据表明，在一项基于人群的老年男性研究中，认知评分可以预测功能衰退。
The purpose of this study was to evaluate a cross-lagged panel model of general cognition and functional abilities over 13 years. The goal was to determine whether general cognitive abilities predict or precede functional decline versus functional abilities predicting cognitive decline. The sample included 3508 men (71–93 years of age at baseline) of the Kuakini Honolulu-Asia Aging Study who were tested repeatedly using a global cognitive test and an assessment of functional capacity. Education and age served as covariates. Cross-lagged models were tested, assessing stationarity of stability and cross-lags. The overall model fit the data well. Cognitive scores had better stability than functional abilities and predicted functional abilities more strongly than functional abilities predicted cognitive scores over time. The strength of all cross-lags increased over time. These longitudinal data show that cognitive scores predicted functional decline in a population-based study of older men.
