The association between dietary diversity and frailty remains unknown in older people. We evaluated whether a limited dietary variety is associated with frailty in older adults with diabetes mellitus (DM). This cross-sectional investigation included 1357 adults (median age: 77 years, women: 61.3%). DM was determined by self-reporting, the Dietary Variety Score (DVS) was used to evaluate dietary variety, and the revised Japanese version of the Cardiovascular Health Study criteria evaluated frailty. Participants were divided into 4 groups: no DM/high DVS (non-DMHV), no DM/low DVS (non-DMLV), DM/high DVS (DMHV), and DM/low DVS (DMLV). The prevalence of frailty in each group was 3.6%, 6.7%, 6.7%, and 12.2%. After adjusting for covariates, logistic regression analysis revealed the highest odds ratio (OR) of frailty in the DMLV (non-DMLV, OR = 2.18 (95% confidence interval (CI): 1.25-3.83); DMHV, OR = 1.87 (95% CI: 0.63-5.52); DML, OR = 5.03 (95% CI: 2.05-12.35)). Another logistic regression analysis revealed that a low DVS and DM were independently associated with frailty. Both a low dietary variety and DM were independently related to frailty in older people and the combination increased the prevalence of frailty. These findings suggest that high dietary variety could be important for the prevention of frailty in people with DM.
膳食多样性与虚弱之间的关系在老年人中尚不清楚。我们评估了饮食种类有限是否与患有糖尿病（DM）的老年人的虚弱有关。这项横断面研究包括 1357 名成年人（中位数年龄：77 岁，女性：61.3％）。DM 通过自我报告确定，使用饮食多样性评分（DVS）评估饮食多样性，使用修订后的日本心血管健康研究标准评估虚弱。参与者分为 4 组：无 DM/高 DVS（非 DMHV），无 DM/低 DVS（非 DMLV），DM/高 DVS（DMHV）和 DM/低 DVS（DMLV）。每组的虚弱发生率分别为 3.6％，6.7％，6.7％和 12.2％。调整混杂因素后，逻辑回归分析显示 DMLV 组（非 DMLV，OR = 2.18（95％置信区间（CI）：1.25-3.83）；DMHV，OR = 1.87（95％CI：0.63-5.52）；DML，OR = 5.03（95％CI：2.05-12.35））的虚弱发生风险最高。另一项逻辑回归分析显示，低 DVS 和 DM 与虚弱独立相关。低饮食多样性和 DM 与老年人的虚弱均独立相关，且两者结合增加了虚弱的发生率。这些发现表明，高饮食多样性对于预防 DM 患者的虚弱可能很重要。
