Abstract

Background

The World Health Organization's Integrated Care for Older People framework emphasizes intrinsic capacity (IC) assessment, yet the relationship between specific intrinsic capacity impairments and self-rated health (SRH) across different age groups remains inadequately characterized.

Objectives

To analyze age-specific associations between six IC domains and self-rated health using Taiwan Longitudinal Study on Aging data, adjusting for demographic, socioeconomic, and health factors.

Methods

We extracted 3,330 participants with good or poor self-rated health, stratified into three age groups: 55−64 years (n = 1,278), 65−74 years (n = 1,011), and 75+ years (n = 1,041). Five sequential logistic regression models assessed associations between IC impairments (locomotor capacity, vitality, vision, hearing, cognition, psychological capacity) and self-rated health, adjusting for sex, education, marital status, employment, economic satisfaction, chronic conditions, smoking, drinking, physical exercise, and sleep quality.

Results

IC impairment prevalence increased with age: 17.2% (55−64), 38.2% (65−74), and 61.5% (75+). After adjustment, age-specific patterns of IC impairments associated with poor self-rated health emerged. In middle-aged adults (55−64), locomotor capacity showed the strongest association with poor self-rated health (OR = 14.61, 95% CI: 3.50–61.01), though the wide confidence interval reflects the low prevalence of impairment. Psychological capacity (OR = 5.96, 95% CI: 3.32–10.69) could thus be the most dominant IC impairment that is linked to poor self-rated health in this age group. For young-old adults (65−74), locomotor capacity had the greatest impact (OR = 4.19, 95% CI: 2.02–8.67), followed by psychological capacity (OR = 3.68, 95% CI: 2.33–5.82) and vitality (OR = 2.14, 95% CI: 1.11–4.16). In the oldest adults (75+), vitality became particularly important (OR = 4.17, 95% CI: 2.22–7.84), alongside with psychological capacity (OR = 3.15, 95% CI: 2.18–4.56) and locomotor capacity (OR = 2.20, 95% CI: 1.52–3.17).

Conclusions

Age-specific patterns suggest targeted interventions: mental health support for middle-aged adults, mobility preservation for young-old adults, and vitality enhancement for the oldest adults. These findings provide guidance for age-tailored ICOPE strategies.

社区居民内在能力障碍与自评健康之间的年龄关联：来自台湾老化纵向研究的见解。

背景：世界卫生组织的老年人综合护理框架强调内在能力（IC）评估，但不同年龄组的特定内在能力损伤与自评健康（SRH）之间的关系仍然没有充分表征。目的：利用台湾老龄化纵向研究资料，在调整人口统计学、社会经济和健康因素后，分析六个IC域与自评健康之间的年龄相关性。方法：我们提取了3330名自评健康状况良好或较差的参与者，分为三个年龄组：55-64岁（n = 1,278）、65-74岁（n = 1,011）和75岁以上（n = 1,041）。五个顺序逻辑回归模型评估了IC损伤（运动能力、活力、视觉、听觉、认知、心理能力）与自评健康之间的关系，调整了性别、教育、婚姻状况、就业、经济满意度、慢性病、吸烟、饮酒、体育锻炼和睡眠质量。结果：IC损伤患病率随年龄增加：55 ~ 64岁为17.2%，65 ~ 74岁为38.2%，75岁以上为61.5%。调整后，出现了与不良自我评价健康相关的IC损伤的年龄特异性模式。在中年人（55-64岁）中，运动能力与自我评价健康状况不佳的相关性最强（OR = 14.61, 95% CI: 3.50-61.01），尽管较宽的置信区间反映了较低的损害发生率。因此，心理能力（OR = 5.96, 95% CI: 3.32-10.69）可能是与该年龄组自我评价健康状况不佳相关的最主要的IC损伤。对于65-74岁的年轻老年人，运动能力的影响最大（OR = 4.19, 95% CI: 2.02-8.67），其次是心理能力（OR = 3.68, 95% CI: 2.33-5.82）和活力（OR = 2.14, 95% CI: 1.11-4.16）。在老年人（75岁以上）中，活力变得尤为重要（OR = 4.17, 95% CI: 2.22-7.84），此外还有心理能力（OR = 3.15, 95% CI: 2.18-4.56）和运动能力（OR = 2.20, 95% CI: 1.52-3.17）。结论：针对不同年龄的模式，建议采取针对性的干预措施：中年人的心理健康支持，年轻老年人的活动能力保持，以及老年人的活力增强。这些发现为制定适合年龄的ICOPE策略提供了指导。

期刊介绍： There is increasing scientific and clinical interest in the interactions of nutrition and health as part of the aging process. This interest is due to the important role that nutrition plays throughout the life span. This role affects the growth and development of the body during childhood, affects the risk of acute and chronic diseases, the maintenance of physiological processes and the biological process of aging. A major aim of "The Journal of Nutrition, Health & Aging" is to contribute to the improvement of knowledge regarding the relationships between nutrition and the aging process from birth to old age.
