This study aimed to examine the association between sleep duration and quality and sarcopenia, assessed by factors such as low muscle mass (LMM), low muscle strength (LMS), and low physical performance (LPP) among older community-dwellers in Japan.
In this cross-sectional study, a total of 2,069 (men, 902; women, 1,167) participants aged 65 to 80 years were included. Sarcopenia and each low physical function were defined using the definitions of the Asian Working Groups of Sarcopenia 2019. Sleep duration was stratified into three categories: short sleep (<6 h), normal sleep (6-8 h), and long sleep (>8 h). Sleep quality was classified into two groups based on 8-item Athens Insomnia Scale score: insomnia (≥6), and non-insomnia (<6). We analyzed the association between sleep parameters and sarcopenia, including low physical functions, by logistic regression analysis.
Compared to normal sleepers, long sleepers had a positive association with sarcopenia (odds ratio [OR] 2.11, 95% confidence interval [CI] 1.25-3.58). In particular, long sleep was strongly associated with LMS (OR 1.77, 95%CI 1.07-2.94) and LPP (OR 1.90, 95%CI 1.25-2.88). On the other hand, poor sleep quality was not associated with sarcopenia in long sleepers, but in normal sleepers.
Long sleep was associated with sarcopenia, including LMS and LPP. However, in long sleepers, insomnia was not associated with sarcopenia or any of its components.
本研究旨在探讨日本社区老年人中睡眠时长和睡眠质量与肌少症的关系，肌少症通过低肌肉量（LMM）、低肌肉力量（LMS）和低身体机能（LPP）等因素来评估。
本横断面研究共纳入了 2069 名年龄在 65 至 80 岁的参与者（男性 902 名，女性 1167 名）。肌少症和每种低身体机能均采用 2019 年亚洲肌少症工作组的定义进行定义。睡眠时长分为三组：短睡眠（<6 小时）、正常睡眠（6-8 小时）和长睡眠（>8 小时）。根据 8 项 Athens 失眠量表评分，将睡眠质量分为两组：失眠（≥6）和非失眠（<6）。我们通过 logistic 回归分析来分析睡眠参数与肌少症（包括低身体机能）之间的关系。
与正常睡眠者相比，长睡眠者与肌少症呈正相关（比值比 [OR] 2.11，95%置信区间 [CI] 1.25-3.58）。特别是，长睡眠与 LMS（OR 1.77，95%CI 1.07-2.94）和 LPP（OR 1.90，95%CI 1.25-2.88）呈强相关。另一方面，在长睡眠者中，睡眠质量差与肌少症无关，但在正常睡眠者中与肌少症有关。
长睡眠与肌少症有关，包括 LMS 和 LPP。然而，在长睡眠者中，失眠与肌少症或其任何组成部分无关。
