Population ageing is a global phenomenon that necessitates consideration of health-related quality of life (HRQoL) in older adults. Previous studies have investigated related factors including mobility, social support and living situations.
This study aimed to provide a network perspective on factors related to HRQoL.
Cross-sectional nationwide data were obtained from the Korean National Health and Nutrition Examination Survey conducted from 2018 to 2020 for network analyses. Data for participants aged 65 years or above were analysed, resulting in a total of 4317 eligible cases. The variables included were EQ-5D (a measure of HRQoL), household income, education, living situation, subjective perceived health, Charlson Comorbidity Index (a measure of medical comorbidities), stress, exercise per week, alcohol consumption and smoking. Three networks were produced: (a) EQ-5D dimensions network, (2) EQ-5D dimensions, lifestyle and psychosocial factors network, and (3) overall EQ-5D index, lifestyle and psychosocial factors network. Node centralities, bridge centralities and edges of the networks were examined.
The most central EQ-5D dimension was the ability to carry out usual activities. In the second network, subjective health, stress and anxiety/depression were revealed as nodes with high bridge centralities. Subjective health, exercise, and Charlson Comorbidity Index were nodes closely linked to the overall EQ-5D index.
The results emphasise the importance of enhancing functional independence and subjective health cognition, increasing routine exercise and reducing stress as targets for interventions to improve HRQoL in older adults.
人口老龄化是一种全球现象，这使得有必要考虑老年人与健康相关的生活质量（HRQoL）。先前的研究调查了包括行动能力、社会支持和生活状况等相关因素。
本研究旨在从网络视角探讨与HRQoL相关的因素。
通过2018年至2020年韩国国家健康与营养检查调查获取全国横断面数据，用于网络分析。对65岁及以上参与者的数据进行分析，最终得到4317例符合条件的病例。纳入的变量包括EQ-5D（HRQoL的一种测量方法）、家庭收入、教育程度、生活状况、主观健康感知、查尔森合并症指数（一种衡量合并症的方法）、压力、每周锻炼量、饮酒情况和吸烟状况。构建了三个网络：（a）EQ-5D维度网络，（2）EQ-5D维度、生活方式和心理社会因素网络，以及（3）总体EQ-5D指数、生活方式和心理社会因素网络。研究了网络的节点中心性、桥接中心性和边。
EQ-5D最核心的维度是进行日常活动的能力。在第二个网络中，主观健康、压力和焦虑/抑郁被揭示为具有高桥接中心性的节点。主观健康、锻炼和查尔森合并症指数是与总体EQ-5D指数紧密相连的节点。
研究结果强调了增强功能独立性和主观健康认知、增加日常锻炼以及减轻压力作为改善老年人HRQoL干预目标的重要性。
