In this study we investigated the correlation between working capacity and APDL of middle-aged and elderly residents of welfare homes for the intellectually retarded. The subjects were 313 intellectually retarded people over 35 years old. The subjects were chosen from residents of four welfare institutions and job-placement centers for intellectually retarded people in Otaru, Hokkaido. Personal attributes, working capacity, and APDL were investigated in each subject. The items of personal attributes were: gender, chronological age, severity of intellectual impairment, and presence/absence of Down's syndrome. Working capacity was evaluated according to the 6 items. APDL was evaluated according to the 51 items. For statistical analysis of the working capacity of the subjects, the variables were summarized using principal component analysis and scored. Next, a search was made for the common factors in the 51 items of APDL using the principal component method. Finally, the correlation between working capacity and APDL was investigated by multiple regression analysis, with the obtained composite scores as dependent variables and the scores of APDL factors extracted by principal component analysis as independent variables. The following three factors were selected for the subjects: health management, outdoor movement and social activity. The multiple correlation coefficient using these three factors was R=0.63 (F=55.20, p<0.01). This indicates the necessity, from the viewpoints of prevention of senility, to focus not only on the decrease in working capacity of aging residents with intellectual impairment in welfare institutions but to establish various countermeasures based on the interrelationship between working capacity and APDL.
在本研究中，我们调查了智障人士福利院中老年居民的工作能力与日常生活活动能力（APDL）之间的相关性。研究对象为313名35岁以上的智障人士。这些对象选自北海道小樽市的四家智障人士福利机构和就业安置中心的居民。对每位研究对象调查其个人属性、工作能力和日常生活活动能力。个人属性项目包括：性别、实足年龄、智力障碍严重程度以及是否患有唐氏综合征。根据6个项目评估工作能力。根据51个项目评估日常生活活动能力。为了对研究对象的工作能力进行统计分析，采用主成分分析法对变量进行汇总并评分。接下来，使用主成分法在51个日常生活活动能力项目中寻找共同因素。最后，以获得的综合评分为因变量，以主成分分析提取的日常生活活动能力因素评分为自变量，通过多元回归分析研究工作能力与日常生活活动能力之间的相关性。为研究对象选取了以下三个因素：健康管理、户外活动和社交活动。使用这三个因素的多元相关系数为R = 0.63（F = 55.20，p < 0.01）。这表明，从预防衰老的角度来看，不仅有必要关注福利机构中智障老年居民工作能力的下降，还需要基于工作能力与日常生活活动能力之间的相互关系制定各种对策。
