目的 為了瞭解老人日常生活活動有障礙者的盛行率和相關因子。方法 於1998年5月以1774個設籍於中興新村之65歲或以上的老人進行橫斷式研究，共有1092人完成問卷調查並參與這次研究，完成率為61.6%。本研究由訪員進行面對面訪視，收集有關受訪老人之社會經濟狀況、生活形態、自覺健康狀態與罹患慢性病之狀況。分析方法包括卡方檢定分析與多變項羅吉斯迥歸分析。結果 其中男性佔65.66%，女生性34.34%，平均年齡為73.4±5.6歲。老人日常活動能力有障礙者的盛行率為10.71%。在控制其他變項之後，以多變項羅吉斯迥歸分析來看，80歲或以上的老人發生日常生活活動障礙的勝算比是65-69歲老人的2.60倍（95%信賴區問為1.40-4.85）。有規則運動的老人，其日常活動能力有障礙的勝算比是沒有規則運動者的0.60倍（95%信賴區問為0.37-0.97）。罹患慢性病與日常活動能力是否有障礙並沒有顯著相關性。結論 年齡越高及沒有規則運動是老人日常活動能力有障礙的相關因子。
Purpose. The aim of this study was to determine the prevalence of impaired activities of daily living (ADL) in older people. Methods. This was a community-based, cross-sectional study conducted at Chung-Hsing Village in Taiwan in May 1998. All individuals aged 65 and over were enrolled. A total of 1092 subjects, out of 1774 registered residents, completed questionnaires and participated in this study. The response rate was 61.6%. Socio-demographic characteristics, lifestyle patterns, health-related behaviors, and chronic diseases were collected by well-trained interviewers. Data were analyzed by chi-square test and multivariate logistic regression. Results. Out of the 1092 subjects, 65.66% were men and 34.34% were women. The mean age was 73.4±5.6 years. The prevalence of impaired ADL was 10.71%. Multivariate logistic regression showed that with the age group 65 to 69 years as a reference, odds ratio for the risk of impaired ADL was considerably higher in people ≥ 80 years (OR=2.60, 95% CI=1.40 to 4.85). With no regular exercise as a reference, odds ratio for the risk of impaired ADL was considerably lower in people who regularly exercised (OR=0.60, 95% CI=0.37 to 0.97). No significant difference in number of chronic diseases was reported for the risk of impaired ADL. Conclusions. Increasing age and no regular exercise are associated with increased risk of impaired ADL in older people.
