OBJECTIVE
To test the hypothesis that elderly persons who feel ikigai (a sense of life worth living) have a lower risk of incident functional disability than those who do not. Recent studies have suggested that ikigai impacts on mortality. However, its impact upon disability is unknown. The aim of the present study was to investigate the association between ikigai and incident functional disability among elderly persons.
METHODS
We conducted a prospective cohort study of 830 Japanese elderly persons aged ≥70 years as a comprehensive geriatric assessment in 2003. Information on ikigai was collected by self-reported questionnaire. Data on functional disability were retrieved from the public Long-term Care Insurance database in which participants were followed up for 11 years. Hazard ratios (HRs) and 95% confidence intervals (CIs) for incidence of functional disability were calculated for three groups delineated according to the presence of ikigai (“no”, “uncertain” or “yes”) using the Cox proportional hazards regression model.
RESULTS
The 11-year incidence of functional disability was 53.3% (442 cases). As compared with the “no” group, the multiple-adjusted HR (95% CI) of incident functional disability was 0.61 (0.36–1.02) for the “uncertain” group and 0.50 (0.30–0.84) for the “yes” group.
CONCLUSION
A stronger degree of ikigai is significantly associated with a lower risk of incident functional disability.
目的
检验这样一种假设，即感觉有生趣（一种有价值的生活感）的老年人发生功能残疾的风险低于没有这种感觉的老年人。最近的研究表明，生趣会影响死亡率。然而，其对残疾的影响尚不清楚。本研究的目的是调查老年人中生趣与发生功能残疾之间的关联。
方法
我们对830名年龄≥70岁的日本老年人进行了一项前瞻性队列研究，作为2003年的一项综合老年评估。通过自我报告问卷收集有关生趣的信息。从公共长期护理保险数据库中检索功能残疾数据，对参与者进行了11年的随访。使用Cox比例风险回归模型，针对根据生趣的存在情况划分的三组（“无”、“不确定”或“有”）计算功能残疾发生率的风险比（HR）和95%置信区间（CI）。
结果
功能残疾的11年发生率为53.3%（442例）。与“无”组相比，“不确定”组发生功能残疾的多因素调整HR（95%CI）为0.61（0.36 - 1.02），“有”组为0.50（0.30 - 0.84）。
结论
更强程度的生趣与更低的发生功能残疾风险显著相关。
