This study investigates the relationships between subjective age, intrinsic capacity, functional ability and health among Norwegians aged 60 years and older. The Norwegian Survey of Health and Ageing (NORSE) is a population-based, cross-sectional study of home-dwelling individuals aged 60-96 years in the former county of Oppland. Age- and sex-adjusted regression models were used to investigate the gap between subjective and chronological age and this gap's association with self-reported and objectively measured intrinsic capacity (covering all six sub domains defined by WHO), health, and functional ability among 817 NORSE participants. The results show most participants felt younger than their chronological age (86.5%), while relatively few felt the same as their chronological age (8.3%) or older (5.2%). The mean subjective age was 13.8 years lower than mean chronological age. Participants with urinal incontinence, poor vision, or poor hearing felt 3.1 [95% confidence interval (CI) (0.6, 5.5)], 2.9 [95% CI (0.2, 5.6)], and 2.9 [95% CI (0.3, 5.5)] years older, respectively, than participants without those conditions, whereas none of the following factors-anxiety, depression, chronic disease, Short Physical Performance Battery score, grip strength, cognition, or frailty-significantly had an impact on the gap. In line with prior research, this study finds that feeling considerably younger than one's chronological age is common at older ages. However, those with poor hearing, poor vision, and urinal incontinence felt less young compared to those not having these conditions. These relationships may exert undesirable effects on vitality and autonomy, which are considered key factors of intrinsic capacity and healthy ageing.
本研究调查了60岁及以上挪威人的主观年龄、内在能力、功能能力与健康之间的关系。挪威健康与老龄化调查（NORSE）是一项基于人群的横断面研究，研究对象为原奥普兰郡60 - 96岁的居家个体。采用年龄和性别调整后的回归模型，研究了817名NORSE参与者的主观年龄与实际年龄之间的差距，以及这一差距与自我报告和客观测量的内在能力（涵盖世界卫生组织定义的所有六个子领域）、健康和功能能力之间的关联。结果显示，大多数参与者感觉自己比实际年龄年轻（86.5%），而感觉与实际年龄相同的参与者相对较少（8.3%），感觉比实际年龄大的参与者更少（5.2%）。主观年龄的平均值比实际年龄的平均值低13.8岁。有尿失禁、视力差或听力差的参与者分别比没有这些情况的参与者感觉大3.1岁[95%置信区间（CI）（0.6，5.5）]、2.9岁[95%CI（0.2，5.6）]和2.9岁[95%CI（0.3，5.5）]，而以下因素——焦虑、抑郁、慢性病、简短体能测试得分、握力、认知或虚弱——均未对这一差距产生显著影响。与先前的研究一致，本研究发现，在老年人中，感觉比实际年龄年轻得多是很常见的。然而，与没有这些情况的人相比，听力差、视力差和有尿失禁的人感觉自己没那么年轻。这些关系可能会对活力和自主性产生不良影响，而活力和自主性被认为是内在能力和健康老龄化的关键因素。
