本研究考察了日本城市社区高级功能能力的现状和纵向变化。居住在东京市中心郊区的65-84岁的人参加了1991年举行的基线调查（n = 814），并随访了8年。结果的措施是残疾：工具性自我维持（IADL），智力活动量表（智力活动）和社会角色量表（社会角色），作为衡量的子量表的东京都老年学研究所的能力指数（TMIG指数的能力）。在基线的三个分量表中，老年男性和女性的社会角色残疾患病率最高，其次是智力活动和IADL残疾。对在TMIG能力指数的所有三个分量表中没有初始残疾的受试者（229名男性和235名女性）进行的8年纵向调查表明，随着年龄的增长，他们最有可能失去社会角色功能，其次是智力活动和IADL。考克斯比例风险模型分析的所有814名参与者显示，基线水平的社会角色和智力活动显着预测新发IADL残疾在8年的随访期间，即使在控制性别，年龄和慢性疾病。总之，在日本城市社区老年人群中，社会角色和智力活动的残疾不仅可能先于IADL残疾，而且还可显著预测未来IADL残疾的发生。(C)2002爱思唯尔科学爱尔兰有限公司保留所有权利。
This study examined the present state and longitudinal changes in higher-level functional capacity in a Japanese urban community. Persons aged 65-84 years living in a suburb of central Tokyo participated in a baseline survey held in 1991 (n = 814) and followed-up for 8 years. Outcome measures were disabilities in: instrumental self-maintenance (IADL), the intellectual activity scale (intellectual activity) and the social role scale (social role), as measured by subscales of the Tokyo Metropolitan Institute of Gerontology Index of Competence (TMIG-index of competence). At baseline among the three subscales, both older men and women had the highest prevalence of disability in social role, followed in turn by intellectual activity and IADL disability. The 8-year longitudinal survey on subjects who had no initial disability (229 men and 235 women) in all three subscales of TMIG-index of competence demonstrated that they were most likely to lose social role function with advancing age, followed in turn by intellectual activity and IADL. The Cox proportional hazard model analysis for all 814 participants revealed that baseline level of social role and intellectual activity significantly predicted the new onset of IADL disability during the 8-year follow-up period even after controlling for gender, age, and chronic medical conditions. In summary, disability in social role and intellectual activity do not only likely precede IADL disability, but also predict significantly the future onset of IADL disability in a Japanese urban community older population.
