To describe lower-extremity functioning in community-dwelling older Mexican Americans and to examine its relationship with medical problems.
Cross-sectional analyses of survey and performance-based data obtained in a population-based study employing area probability sampling.
Households within selected census tracts of five Southwestern states: Arizona, California, Colorado, New Mexico, and Texas.
A total of 2873 Mexican Americans aged 65 years and older.
A multidimensional questionnaire assessing demographic, sociocultural, and health variables. Standardized tests of lower-extremity physical functioning included measures of standing balance, repeated chair stands, walking, and an overall summary measure.
Regression analyses revealed that being more than age 75 and female, having arthritis diabetes, visual impairments, or being obese or underweight were all significantly associated with performance on both individual and summary tests of lower-extremity functioning. In separate regression analyses, the total number of medical conditions was also associated with performance.
The likelihood of predicting performance or inability to complete tests of lower-extremity functioning was greatest for those aged 80 and older, those with arthritis or diabetes, and those with three or more medical conditions. Because of the high prevalence of diabetes in Mexican Americans, documentation of the association of diabetes with performance-based tests of lower-extremity functioning may help guide early interventions targeted to prevent progression to more severe limitations or disability.
描述居住在社区的老年墨西哥裔美国人的下肢功能，并研究其与医疗问题的关系。
对基于区域概率抽样的人群研究中获得的调查数据和基于表现的数据进行横断面分析。
亚利桑那州、加利福尼亚州、科罗拉多州、新墨西哥州和得克萨斯州这五个西南部州选定普查区的家庭。
共有2873名65岁及以上的墨西哥裔美国人。
一份评估人口统计学、社会文化和健康变量的多维问卷。下肢身体功能的标准化测试包括站立平衡、重复起坐、行走测量以及一项综合汇总测量。
回归分析显示，年龄超过75岁且为女性、患有关节炎、糖尿病、视力障碍、肥胖或体重过轻，均与下肢功能的单项测试和汇总测试表现显著相关。在单独的回归分析中，医疗状况的总数也与表现相关。
对于80岁及以上的人群、患有关节炎或糖尿病的人群以及患有三种或更多医疗状况的人群，预测下肢功能测试表现或无法完成测试的可能性最大。由于墨西哥裔美国人中糖尿病的高患病率，记录糖尿病与基于表现的下肢功能测试之间的关联可能有助于指导早期干预，以防止病情发展为更严重的功能受限或残疾。
