Abstract

Background: The spread of coronavirus disease 2019 (COVID-19) has dramatically altered the lifestyles of many people worldwide. Several studies reported that body weight of young adults increased during the COVID-19 pandemic; however, weight loss has been observed in the elderly population. Therefore, trends in body composition due to the COVID-19 pandemic may vary depending on the characteristics of the population. This study aimed to investigate the changes in body mass index (BMI), muscle mass, and fat mass before and during the COVID-19 pandemic among patients undergoing hemodialysis.

Methods: In this retrospective longitudinal study, we enrolled 115 clinically stable outpatients (mean age: 65.7 ± 11.2 years, 62.6% men) who underwent hemodialysis thrice a week. Baseline data were collected between April 2019 and March 2020, before the declaration of the COVID-19 emergency by the Japanese government. The follow-up measurements were performed between July 2020 and March 2021 during the COVID-19 pandemic. Patient characteristics, laboratory data, and BMI measurements were collected from the medical records. Muscle mass and fat mass were measured using bioelectrical impedance analysis.

Results: BMI and fat mass among the study participants were significantly higher during the COVID-19 pandemic than before the pandemic (p < 0.01), but no significant change in muscle mass was observed. A restricted cubic spline function showed that the increase in BMI appeared to correlate well with fat mass, but not with muscle mass.

Conclusions: BMI and fat mass of patients on hemodialysis significantly increased due to preventive measures against the COVID-19 pandemic in Japan. These findings may provide useful information in making nutritional management decisions for patients undergoing hemodialysis during and after the COVID-19 pandemic.

2019冠状病毒病大流行期间血液透析患者身体成分的变化:一项回顾性纵向研究
背景:2019冠状病毒病(COVID-19)的传播极大地改变了全世界许多人的生活方式。几项研究报告称,在2019冠状病毒病大流行期间,年轻人的体重增加;然而,在老年人中观察到体重减轻。因此,COVID-19大流行导致的身体成分变化趋势可能因人群特征而异。本研究旨在调查血液透析患者在COVID-19大流行之前和期间的体重指数(BMI)、肌肉质量和脂肪质量的变化。方法:在这项回顾性纵向研究中,我们招募了115例临床稳定的门诊患者(平均年龄:65.7±11.2岁,男性62.6%),每周进行3次血液透析。基线数据是在日本政府宣布COVID-19紧急状态之前的2019年4月至2020年3月期间收集的。在2019冠状病毒病大流行期间,于2020年7月至2021年3月进行了随访测量。从医疗记录中收集患者特征、实验室数据和BMI测量值。用生物电阻抗分析法测定肌肉量和脂肪量。结果:在COVID-19大流行期间,研究参与者的BMI和脂肪量明显高于大流行前(p)结论:由于日本对COVID-19大流行的预防措施,血液透析患者的BMI和脂肪量显着增加。这些发现可能为COVID-19大流行期间和之后接受血液透析的患者制定营养管理决策提供有用的信息。
