目的 基于可行能力生命质量视角，探索65岁及以上老年大骨节病（Kashin-Beck disease，KBD）患者现状及影响因素，为制订综合干预策略提供依据。方法 2024年10-12月,整群抽样法选取西安市临潼区222名老年KBD患者为研究对象。采用一般资料调查表和老年人可行能力生命质量量表（investigating choice experiments capability for older people，ICECAP-O）对其进行调查，并进行单因素分析、Spearman相关分析及多元线性回归分析。结果 老年KBD患者的ICECAP-O总分为（0.63±0.18）。依靠感、角色感和快乐感维度的“完全无能力”水平占比较高，而“完全能力”水平则以角色感占比最高。多元线性回归显示，年龄、独居情况、文化程度、疾病程度和患病年限均是患者可行能力生命质量的影响因素（均P＜0.05）。结论 老年KBD患者可行能力生命质量受年龄、躯体损伤及社会心理因素共同影响。ICECAP-O量表可揭示传统生命质量评估未覆盖的维度，为提升患者整体生命质量提供新视角。

Objective To explore the status and influencing factors of capability and quality of life in elderly patients (≥65 years) with Kashin-Beck disease (KBD) from the perspective of the capability approach,and to provide a basis for developing comprehensive intervention strategies.Methods From October to December 2024,222 elderly KBD patients in Lintong District of Xi’an were selected by cluster sampling,and were surveyed with the General Information Questionnaire and the investigating choice experiments capability for older people（ICECAP-O）.Univariate analysis,Spearman correlation analysis,and multiple linear regression analysis were performed.Results The total ICECAP-O score of elderly KBD patients was (0.63±0.18).The dimensions of attachment (9.46%),role (10.81%),and enjoyment (10.36%) had relatively high proportions of respondents at the “no capability” level,while the role dimension (13.96%) had the highest proportion at the “full capability” level.Multiple linear regression showed that age,living alone,education level,disease severity,and duration of illness were influencing factors of the patients’ capability-related quality of life (all P＜0.05).Conclusions The capability-related quality of life in these patients is jointly influenced by age,physical impairment,and psychosocial factors.The ICECAP-O scale can reveal dimensions not covered by traditional quality of life assessments,providing a new perspective for improving the quality of life of such patients.
