The population of older adults is growing, posing new challenges for society and healthcare services. Instrumental Activities of Daily Living (IADL) describe individuals' ability to handle more complex activities in their daily life and to the extent to which they can live independently. Self-rated health (SRH) is a frequently used metric in health research and is a robust predictor for institutionalization and mortality. Therefore, the purpose of this study is to investigate the association between IADL function and SRH among community-dwelling older adults in Norway, and to determine the influence of cognitive function.
A total of 1104 community-dwelling adults aged 70 or older participating in the population-based Trøndelag Health Study (HUNT) 4 Trondheim 70 + were included. Logistic regression was used to examine the association between IADL function and SRH. IADL function was divided into two groups, IADL limitation (requiring help to complete one or more daily activities) and no IADL limitation. SRH were dichotomized into good and poor SRH.
Of the 1104 included participants 127 (11.5%) experienced IADL limitation. After adjustment for gender, age, cohabiting status, educational level, physical activity, gait speed, grip strength, depressive symptoms, limiting long-term illness and cognitive function, participants with IADL limitation had significantly higher odds of poor SRH compared to those without IADL limitation (odds ratio 3.26, 95% confidence interval 1.89-5.61, p < 0.001).
These cross-sectional results from an urban population of community-dwelling older adults showed a strong association between IADL limitation and poor SRH independent of cognitive function, emphasizing the importance of investigating the prospective relationship between IADL and SRH. Intervention studies are needed to confirm whether improving IADL function can impact SRH in older adults.

老年人口正在增长，给社会和医疗服务带来了新的挑战。日常生活工具性活动（IADL）描述了个体处理日常生活中更复杂活动的能力以及他们能够独立生活的程度。自评健康（SRH）是健康研究中常用的指标，并且是机构化和死亡率的有力预测指标。因此，本研究的目的是调查挪威社区居住的老年人中IADL功能与SRH之间的关联，并确定认知功能的影响。
总共纳入了1104名年龄在70岁及以上、参与基于人群的特隆赫姆健康研究（HUNT）4特隆赫姆70+的社区居住成年人。采用逻辑回归来检验IADL功能与SRH之间的关联。IADL功能分为两组，即IADL受限（完成一项或多项日常活动需要帮助）和无IADL受限。SRH分为良好和不良SRH。
在1104名纳入的参与者中，127名（11.5%）经历了IADL受限。在对性别、年龄、同居状况、教育水平、身体活动、步速、握力、抑郁症状、长期疾病限制和认知功能进行调整后，与无IADL受限的参与者相比，IADL受限的参与者健康自评不良的几率显著更高（优势比3.26，95%置信区间1.89-5.61，p<0.001）。
这些来自城市社区居住老年人的横断面结果显示，IADL受限与健康自评不良之间存在密切关联，且独立于认知功能，强调了研究IADL与SRH之间前瞻性关系的重要性。需要进行干预研究来确认改善IADL功能是否会影响老年人的SRH。
