背景和目的。亚拉巴马大学伯明翰分校（UAB）的老年生活空间评估（LSA）研究是一种相对较新的测量流动性的工具。本报告的目的是描述LSA和身体功能，社会人口特征，抑郁症和认知状态的传统措施之间的关系。科目受试者为998例分层随机样本。医疗保险受益人年龄≥ 65岁。样本是50%的非洲裔美国人，50%的男性，50%来自农村（与城市）县。方法.进行了家庭访谈。使用LSA测量活动性，记录受试者在评估前4周内旅行的地点和频率以及所需的任何帮助。测定了基本日常生活活动（ADL）和工具性日常生活活动（IADL）、认知状态、收入水平、抑郁症状的存在和交通资源。使用短期身体机能成套测验（SPPB）评估身体机能。结果简单的双变量相关性表明LSA与除居住地（农村与城市）外的所有变量之间存在显着关系。在回归模型中，身体功能（ADL，IADL）和身体机能（SPPB）解释了LSA评分的45.5%的方差。另外12.7%的方差由社会人口学变量解释，不到1%由认知和抑郁症状解释。讨论和结论。LSA可用于记录患者在家中和社区内的移动性。LSA分数与一个人的身体能力和其他可能限制移动性的因素有关。这些分数可以与其他测试和测量结合使用，以产生临床假设来解释移动性缺陷，并计划适当的干预措施来解决这些缺陷。
Background and Purpose. The University of Alabama at Birmingham (UAB) Study of Aging Life-Space Assessment (LSA) is a relatively new instrument to measure mobility. The purpose of this report is to describe the relationships between LSA and traditional measures of physical function, sociodemographic characteristics, depression, and cognitive status. Subjects. Subjects were,a stratified random sample of 998. Medicare beneficiaries aged >= 65 years. The sample was 50% African American, 50% male, and 50% from rural (versus urban) counties. Methods. In-home interviews were conducted. Mobility was measured using the LSA, which documents where and how often subjects travel and any assistance needed during the 4 weeks prior to the assessment. Basic activities of daily living (ADL) and instrumental activities of daily living (IADL), cognitive status, income level, presence of depressive symptoms, and transportation resources were determined. The Short Physical Performance Battery (SPPB) was used to assess physical performance. Results. Simple bivariate correlations indicated a significant relationship between LSA and all variables except residence (rural versus urban). In a regression model, physical function (ADL, IADL) and physical performance (SPPB) accounted for 45.5% of the variance in LSA scores. An additional 12.7% of the variance was explained by sociodemographic variables, and less than 1% was explained by cognition and depressive symptoms. Discussion and Conclusion. The LSA can be used to document patients' mobility within their home and community. The LSA scores are associated with a person's physical capacity and other factors that may limit mobility. These scores can be used in combination with other tests and measures to generate clinical hypotheses to explain mobility deficits and to plan appropriate interventions to address these deficits.
