Pain status is a common concern among older adults and has been linked to functional limitations. This study aimed to examine the association between pain status and disabilities risk in basic activities of daily living (BADL) and instrumental activities of daily living (IADL) in older adults in China, using data from the 2020 China Health and Retirement Longitudinal Study (CHARLS). A cross-sectional analysis was conducted using data from 8102 participants aged 60 and older from the 2020 CHARLS. Univariate and multivariate binary logistic regression analyses were performed to assess the association between pain status and BADL/IADL disabilities. We further examined the contribution of each covariate and categorized participants by pain location and number of pain sites. Subgroup analyses were conducted to examine the consistency of findings across demographic and health-related factors. Pain status was significantly associated with higher odds of both BADL and IADL disabilities ( < 0.05), even after adjusting for covariates. Self-rated health and depressive symptoms exerted the greatest influence on the OR values. Pain in any anatomical region, particularly when present at multiple sites, was associated with increased odds of disability. Head and neck pain was specifically associated with IADL disability, while pain in the upper limbs, torso, and lower limbs was associated with both BADL and IADL disabilities. Subgroup analyses confirmed the robustness of these associations. Pain status, especially multisite pain, is significantly associated with BADL and IADL disabilities in older Chinese adults. Although causality cannot be inferred due to the study's cross-sectional design, these findings underscore the importance of addressing pain alongside other health and psychological factors when developing strategies to support functional independence in aging populations.
疼痛状况是老年人普遍关注的问题，并且与功能受限有关。本研究旨在利用2020年中国健康与养老追踪调查（CHARLS）的数据，探讨中国老年人的疼痛状况与日常生活基本活动（BADL）和日常生活工具性活动（IADL）中的残疾风险之间的关联。使用来自2020年CHARLS的8102名60岁及以上参与者的数据进行了横断面分析。进行单变量和多变量二元逻辑回归分析，以评估疼痛状况与BADL/IADL残疾之间的关联。我们进一步检查了每个协变量的贡献，并按疼痛部位和疼痛部位数量对参与者进行分类。进行亚组分析以检验不同人口统计学和健康相关因素的研究结果的一致性。即使在调整协变量后，疼痛状况与BADL和IADL残疾的较高几率仍显著相关（<0.05）。自评健康和抑郁症状对OR值的影响最大。任何解剖区域的疼痛，特别是在多个部位出现时，都与残疾几率增加有关。头颈部疼痛与IADL残疾特别相关，而上肢、躯干和下肢的疼痛与BADL和IADL残疾均相关。亚组分析证实了这些关联的稳健性。疼痛状况，尤其是多部位疼痛，与中国老年成年人的BADL和IADL残疾显著相关。尽管由于本研究的横断面设计无法推断因果关系，但这些发现强调了在制定支持老年人群功能独立性的策略时，将疼痛与其他健康和心理因素一并考虑的重要性。
