This study assessed the association between arthritis, functional impairment, and nutritional risk (NR). Cross-sectional data were from the Canadian Longitudinal Study on Aging, a nationally representative sample of 45-85-year-old community-dwelling Canadians (n = 41,153). The abbreviated Seniors in the Community: Risk Evaluating for Eating and Nutrition II (SCREEN II-AB) Questionnaire determined NR scores (continuous), and high NR (score < 38); the Older American Resources and Services scale measured functional impairment. NR scores and status (low/high) were modelled using multiple linear and logistic regressions, respectively. Analyses adjusted for demographic characteristics, functional impairment, and health (body mass index, self-rated general and mental health). Additional analyses stratified the models by functional impairment. People with arthritis had poorer NR scores (B: - 0.35, CI - 0.48, - 0.22; p < 0.05) and increased risks of high NR (OR 1.11, 95% CI 1.06, 1.17). Among those with functional impairment, the likelihood of high NR was 31% higher in people with arthritis compared to those without arthritis (95% CI 1.12, 1.53). Among those with no functional impairment, the likelihood of high NR was 10% higher in people with arthritis compared to those without (95% CI 1.04, 1.16). These relationships differed based on the type of arthritis. Arthritis is associated with high NR in community-dwelling older adults, both with and without functional impairment. Findings highlight the need for further research on these relationships to inform interventions and improve clinical practices.
本研究评估了关节炎、功能障碍和营养风险（NR）之间的关联。横断面数据来自加拿大老龄化纵向研究，这是一项针对 45-85 岁社区居住的加拿大人群（n=41153）的全国代表性样本。简化的老年人社区：营养风险评估 II（SCREEN II-AB）问卷确定了 NR 评分（连续），高 NR（评分<38）；老年人资源和服务量表测量了功能障碍。分别使用多元线性和逻辑回归模型对 NR 评分和状态（低/高）进行建模。分析调整了人口统计学特征、功能障碍和健康状况（体重指数、自我报告的一般和心理健康）。进一步的分析按功能障碍对模型进行分层。患有关节炎的人 NR 评分较差（B：-0.35，CI-0.48，-0.22；p<0.05），且发生高 NR 的风险增加（OR 1.11，95% CI 1.06，1.17）。在有功能障碍的人群中，与无关节炎人群相比，有关节炎人群发生高 NR 的可能性高 31%（95% CI 1.12，1.53）。在无功能障碍的人群中，与无关节炎人群相比，有关节炎人群发生高 NR 的可能性高 10%（95% CI 1.04，1.16）。这些关系因关节炎类型而异。关节炎与社区居住的老年人群中，无论是否存在功能障碍，都与高 NR 相关。这些发现强调需要进一步研究这些关系，以为干预措施提供信息并改善临床实践。
