The authors regret that the number of years follow up was incorrectly listed in both the Abstract and the first paragraph of the Results section. The full and correct Abstract and corrected first paragraph of the Results section are detailed below; Abstract 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. 3. Results Over 11 years of follow-up, the number of participants with functional disability was 442, and the total number of deaths without functional disability was 207. Moreover, 41 participants moved out. The authors would like to apologise for any inconvenience caused.
