本研究通过对1999年至2001年居住在社区的非残疾老年日本队列进行为期2年的观察，探讨认知障碍、福尔斯和尿失禁（UI）是否是功能下降的独立预测因素。本研究分析了基线时年龄在70-94岁之间的139名男性和214名女性，他们在日常生活活动（ADL）和工具性日常生活活动（IADL）方面都是独立的。独立变量，如认知功能障碍，福尔斯，UI，和其他可能的因素与功能下降，从采访调查中获得的基线。因变量为2年随访时获得的ADL和IADL功能状态。在2年的随访中，认知功能是IADL依赖和ADL和/或IADL依赖的重要预测因子。使用一组简易精神状态检查（MMSE）评分为30-27分的受试者作为参考组，发现较低的MMSE评分与功能下降的比值比增加之间存在显著相关性。较低的认知功能是功能下降的一个重要预测因素，即使在那些认知功能被认为在正常范围内的老年日本人中也是如此。(c)2005爱思唯尔爱尔兰有限公司保留所有权利。
This study examined whether cognitive impairment, falls, and urinary incontinence (UI) were independent predictors of functional decline using a 2-year observation of a non-disabled older Japanese cohort living in a community from 1999 to 2001. A total of 139 men and 214 women aged 70-94 years at the baseline who were independent in both activities of daily living (ADL) and instrumental activities of daily living (IADL) were analyzed in this study. Independent variables, such as cognitive impairment, falls, UI, and other possible factors associated with functional decline were obtained from an interview survey at the baseline. A dependent variable was functional status in ADL and IADL obtained at the time of the 2-year follow-up. During the 2-year follow-up, cognitive function was a significant predictor for both IADL dependence and ADL and/or IADL dependence. Using a group of subjects with Mini Mental State Examination (MMSE) scores of 30-27 points as a reference group, a significant correlation was identified between lower MMSE scores and an increased odds ratio for functional decline. Lower cognitive function was a significant predictor of functional decline, even among those older Japanese whose cognitive function was deemed to be within the normal range.
