CONSEQUENCES OF FEAR OF FALLING AND ACTIVITY RESTRICTION

该项目广泛的长期目标是利用从流行病学研究中获得的知识来制定干预策略，以满足害怕跌倒的老年人和因害怕跌倒而减少活动的老年人的需要。这项建议的具体目的是：1)确定a)害怕跌倒的老年人(以下称为害怕独自摔倒的老年人)不会因为这种恐惧而减少活动的独特的身体、心理社会和人口统计学特征，以及b)害怕跌倒的老年人由于这种恐惧而减少活动(以下称为害怕跌倒和相关的活动限制)；2)评估对跌倒的恐惧和相关的活动限制在三年内对日常生活基本活动(BADL)和工具性日常生活活动(IADL)中自我报告功能变化的影响；以及(3)确定三年内对跌倒的恐惧与功能衰退之间的关系是否通过身体能力的下降来调节。

The broad long term objective of this project is to use the knowledge gained from epidemiologic studies to develop intervention strategies tailored to the needs of older adults with fear of falling and those who cut down on activities due to fear of falling. The specific aims of this proposal are: 1) To identify the distinctive physical, psychosocial, and demographic characteristics of a) older adults with a fear of falling who do not cut down on activity due to that fear (hereafter known as those with fear of falling alone), and b) older adults with fear of falling who cut down on activity due to that fear (hereafter known as those with fear of falling and associated activity restriction); 2) To evaluate the effects of fear of falling and associated activity restriction on changes in self-reported function in basic activities of daily living (BADL) and instrumental activities of daily living (IADL) over a three-year period; and 3) To determine whether the relationship between fear of falling and functional decline over a three-year period is mediated by decline in physical capabilities.
