背景由于冠状病毒病(新冠肺炎)的流行，对户外活动的限制导致了体力活动的减少；这可能会导致老年人的骨骼减少和虚弱。我们最近的研究表明，在大流行的第一波(2020年4月至5月)之后，居住在日本社区的老年妇女的躯干肌肉质量立即显著减少。在本研究中，我们通过比较下列评估期之间的身体测量来进一步检验肌肉质量的恢复或恶化：第一波大流行前，第一波大流行后立即，以及之后一年的随访。方法本研究对77名女性(78.0±15.7岁)进行了肌肉质量、握力、单腿站立能力(S)和口腔运动技能的身体测量，并回答了关于社交(社交网络、参与、结果第一波后即刻外出频度和主观能力感显著降低；在1年的随访期(P<；0.001)，这些都恢复了。在比较肌肉指标时，躯干肌肉质量指数在第一波后立即优先下降，但在1年后显著恢复(P<；0.001)。相反，阑尾骨骼肌质量指数和握力持续下降，直到1年随访(P<；分别为0.001和0.03)。S的单腿站立能力和口腔运动技能在整个评估期间没有明显变化。在此期间，石棺减少症和石棺减少症的患病率呈上升趋势(P=0.068)。社会性活动的减少和随后的恢复模式与躯干肌肉质量相似。结论我们的研究结果显示，在第一波新冠肺炎大流行后1年，骨骼肌质量和力量的可逆性存在差异：躯干肌肉质量急剧下降并迅速恢复，而ASMI和握力持续下降。骨骼肌恢复和恶化的这些差异可能有助于制定在社区居住的老年人中预防新冠肺炎相关石棺减少的短期或长期战略。
BackgroundRestrictions on outdoor movements due to the coronavirus disease (COVID‐19) pandemic have led to a decreased physical activity; this can lead to sarcopenia and frailty in older adults. Our recent study has demonstrated a significant decrease in the trunk muscle mass immediately after the pandemic's first wave (April–May 2020) among Japanese community‐dwelling older women. In the present study, we further examined whether muscle mass recovery or deterioration occurs after 1 year of the pandemic's first wave by comparing physical measurements among the following assessment periods: before the first wave, immediately after the first wave, and at 1‐year follow‐up thereafter.MethodsThis study included 77 women (78.0 ± 5.7 years) who underwent physical measurements for muscle mass, grip strength, one‐leg stand‐up ability (3 s), and oral motor skills and answered questionnaires on sociality (social network, participation, and support) in the three assessment periods.ResultsThe frequency of going out and the subjective vitality were significantly decreased immediately after the first wave; these recovered at the 1‐year follow‐up (P< 0.001). When comparing muscular measures, the trunk muscle mass index preferentially decreased immediately after the first wave but recovered significantly at the 1‐year follow‐up (P< 0.001). Conversely, the appendicular skeletal muscle mass index (ASMI) and grip strength continued to decrease until the 1‐year follow‐up (P< 0.001 andP= 0.03, respectively). The ability to perform a one‐leg stand‐up for 3 s and the oral motor skills did not change significantly across the assessment periods. The prevalence of pre‐sarcopenia and sarcopenia tended to increase during these periods (P= 0.068). The reduction and subsequent recovery patterns for sociality were similar to those observed for the trunk muscle mass.ConclusionsOur findings demonstrated differences in the reversibility of skeletal muscle mass and strength at 1 year after the first wave of the COVID‐19 pandemic: the trunk muscle mass declined acutely and recovered rapidly, whereas the ASMI and grip strength declined continuously. These differences in the skeletal muscle recovery and deterioration might help formulate short‐term or long‐term strategies for COVID‐19‐related sarcopenia prevention in community‐dwelling older adults.
