目的：本文报道了一项以社区为基础的研究的设计，该研究侧重于流行和偶发疾病的影响以及其他修饰性影响，对中、重度残疾老年妇女在3年期间的功能变化[妇女健康与老龄化研究(WHAS)][妇女健康与老龄化研究(WHAS)][妇女的健康和老龄化研究(WHAS)]进行了设计。方法：在代表65岁及以上妇女的大社区样本中，开发了一种概念化和评估残疾的方法，该方法涵盖了广泛的活动和任务中的功能困难，并以简短的筛查工具的形式使用，以识别中度到重度残疾的老年妇女。符合研究标准的女性被招募进行基线访谈、3小时的家庭临床检查，以及每隔6个月进行一次随访访谈和体能测试。结果：筛查人群中中到重度残疾的患病率被证明与国家数据分析所预期的大鼠相似(约三分之一)。筛查面试回复率为78%，符合残疾标准的妇女参与的比例为71%。只有同时完成基线面试和临床检查的女性才被算作受访者。对参与者和非参与者的特征分析表明，选择偏向与残疾程度无关。然而，教育、种族和年龄与参与度有关。受过一定大学教育的女性、黑人女性和年轻女性更有可能参与。结论：在WHAS中识别和招募中重度残疾老年妇女的方法是可行的，并适用于其他以社区为基础的研究，其中纳入几个功能领域的中重度残疾老年人是一个目标。研究设计的其他方面，如使用代理受访者，MILL也影响招募功能受损的个人进入流行病学研究。Ann Epidinool 1999；9：498-507，(C)1999 Elsevier Science Inc.保留所有权利。
PURPOSE: This paper reports on the design of a community-based study focusing on the effects of prevalent and incident disease and other modifying influences, on changes in functioning among moderately and severely disabled elderly women over a 3-year period [the Women's Health and Aging Study (WHAS)].METHODS: An approach to conceptualizing and assessing disability which captured functional difficulty across a broad range of activities and tasks was developed, tested on existing national data, and used, in the form of a brief screening instrument, to identify moderately to severely disabled elderly women in a large community sample representative of women 65 and older. Women meeting study criteria were recruited for a baseline interview, a 3-hour in-home clinical exam, as well as follow-up interviews and physical performance tests at 6-month intervals for three years.RESULTS: Prevalence of moderate to severe disability among the screened population proved similar to rat expected from analysis of national data (about one-third). The screening interview response rate was 78%, and 71% of women eligible by disability criteria participated. Only women completing both the baseline interview and clinical exam were counted as respondents. Analysis of characteristics of participants and nonparticipants indicated no selection bias related to levels of disability. However, education, race, and age were associated with participation. Women with some college education, black women, and younger women were more likely To participate.CONCLUSIONS: The approach used to identify and recruit moderately to severely disabled elderly women in the WHAS is both feasible and applicable to other community-based research where inclusion of elderly people with moderate to severe disability across several areas of functioning is an objective. Other aspects of study design, such as use of proxy respondents, mill also affect recruitment of individuals with impaired functioning into epidemiologic studies.
