To estimate the impact of self-reported diagnosis of arthritis at baseline on the two year incidence of limitation in activities of daily living and instrumental activities of daily living in initially non-disabled Mexican-American elderly.
Longitudinal study. SETTING Southwestern United States (Texas, New Mexico, Colorado, Arizona and California).
A probability sample of 2,167 non-institutionalized Mexican-American men and women, aged 65 or older.
Having ever been told by a doctor that a subject had arthritis, Activities of Daily Living (ADL), Instrumental Activities of Daily Living (IADL), depressive symptomatology, presence of chronic diseases (diabetes mellitus, heart attack, stroke, cancer), and body mass index (BMI).
Among non-disabled persons at baseline, 11.2% of subjects with arthritis reported at least one ADL limitation after two years, compared to 6.9% of subjects without arthritis. Similarly, among non-disabled persons at baseline, 34.7% of subjects with arthritis reported at least one IADL limitation after two years, compared to 27.0% of subjects without arthritis. In logistic regression analysis, depression, diabetes, and arthritis were found to be predictive of the development of ADL disability, controlling for sociodemographic variables. Depression was the only condition that significantly predicted IADL disability.
Subjects with arthritis were more likely to develop ADL and IADL disability over a two-year period than those without arthritis.
评估基线时自我报告的关节炎诊断对最初未残疾的墨西哥裔美国老年人日常生活活动受限和工具性日常生活活动受限两年发病率的影响。
纵向研究。地点：美国西南部（得克萨斯州、新墨西哥州、科罗拉多州、亚利桑那州和加利福尼亚州）。
2167名65岁及以上未入住机构的墨西哥裔美国男性和女性的概率样本。
是否曾被医生告知患有关节炎、日常生活活动（ADL）、工具性日常生活活动（IADL）、抑郁症状、慢性病（糖尿病、心脏病发作、中风、癌症）的存在情况以及体重指数（BMI）。
在基线时未残疾的人群中，患有关节炎的受试者中有11.2%在两年后报告至少有一项ADL受限，而无关节炎的受试者中这一比例为6.9%。同样，在基线时未残疾的人群中，患有关节炎的受试者中有34.7%在两年后报告至少有一项IADL受限，而无关节炎的受试者中这一比例为27.0%。在逻辑回归分析中，发现抑郁、糖尿病和关节炎可预测ADL残疾的发生，同时控制了社会人口统计学变量。抑郁是唯一能显著预测IADL残疾的因素。
与无关节炎的受试者相比，患有关节炎的受试者在两年内更有可能出现ADL和IADL残疾。
