To investigate the relationship between diet and frailty in community-dwelling older adults during the period of restriction on outings due to novel coronavirus disease 2019 (COVID-19).
A mail survey targeting adults aged 65 years or older, including questions on sex, age, height, weight, and social participation, was conducted in May 2020. The participants' dietary variety score and frailty score were then calculated.
Overall, 322 women aged 65 years or older and who were living in the community were recruited for the study; 253 were finally analyzed. The mean age of the 253 participants was 80.0 ± 6.4 years. The dietary variety score and frailty scores were significantly correlated in the linear regression analysis (β: -0.224, p < .001). In the multivariate regression analysis, these factors remained significantly correlated in Model 1, which was adjusted for age (β: -0.229, p < .001), and Model 2, which was adjusted for age, body mass index, and other confounding factors (β: -0.208, p = .001).
Diet was correlated with frailty in older adults living in the community during the period of restriction on outings due to COVID-19.
调查在因 2019 年新型冠状病毒病（COVID-19）而限制外出期间，社区居住的老年人饮食与虚弱之间的关系。
2020 年 5 月，针对年龄在 65 岁及以上的成年人进行了一项邮件调查，内容包括性别、年龄、身高、体重和社会参与度等问题。然后计算了参与者的饮食多样性评分和虚弱评分。
共招募了 322 名年龄在 65 岁及以上、居住在社区的女性进行研究；最终分析了 253 名参与者。253 名参与者的平均年龄为 80.0 ± 6.4 岁。线性回归分析显示，饮食多样性评分和虚弱评分呈显著负相关（β：-0.224，p<0.001）。在多元回归分析中，模型 1（调整年龄）和模型 2（调整年龄、体重指数和其他混杂因素）中这些因素仍呈显著负相关（β：-0.229，p<0.001；β：-0.208，p=0.001）。
在 COVID-19 限制外出期间，社区居住的老年人的饮食与虚弱有关。
