The purpose of this investigation was to examine the prevalence, related factors, and cut-off value of body mass index for sarcopenia in community-dwelling elderly covered by long-term care insurance.
Design was a cross-sectional study, in which113 consecutive community-dwelling elderly with long-term care insurance who underwent rehabilitation at a daycare center in Japan from January 2016 to January 2018, those who were aged ≥65 years old and could walk were included. Those in whom skeletal muscle mass index could not be measured were excluded. The determination of sarcopenia was made according to the criteria of the Asian Working Group for Sarcopenia. We analyzed the data with the unpaired t-test, χ test, logistic regression analysis, and receiver operating characteristic curves.
The 99 elderly meeting the criteria were included and divided into the sarcopenia group (n=36) and no sarcopenia group (n=63). The prevalence was 36.4%. The sarcopenia group was significantly older and had lower body mass index, skeletal muscle mass index, and grip strength than the group without sarcopenia (p <0.05). Age and body mass index were extracted as significant sarcopenia- related factors (p <0.05). The cut-off value of body mass index for sarcopenia was 22.6 kg/m.
The prevalence of sarcopenia in the elderly in the long-term care insurance region was 36.4%, and age and body mass index were extracted as sarcopenia-related factors. The cut-off value of body mass index for sarcopenia was 22.6 kg/m.
本研究旨在调查长期护理保险覆盖的社区老年人中肌少症的患病率、相关因素及体质指数的截断值。
采用横断面研究设计，纳入 2016 年 1 月至 2018 年 1 月期间在日本日间护理中心接受康复治疗的 113 例连续的、有长期护理保险的社区老年人，纳入标准为年龄≥65 岁且能够行走，排除无法测量骨骼肌质量指数的患者。肌少症的诊断标准采用亚洲肌少症工作组的标准。采用独立样本 t 检验、χ 检验、logistic 回归分析和受试者工作特征曲线对数据进行分析。
符合标准的 99 例老年人被纳入研究，并分为肌少症组（n=36）和非肌少症组（n=63）。肌少症的患病率为 36.4%。肌少症组年龄较大，体质指数、骨骼肌质量指数和握力均低于非肌少症组（p<0.05）。年龄和体质指数是显著的肌少症相关因素（p<0.05）。肌少症的体质指数截断值为 22.6 kg/m。
长期护理保险覆盖地区老年人肌少症的患病率为 36.4%，年龄和体质指数是肌少症的相关因素。肌少症的体质指数截断值为 22.6 kg/m。
