老年女性肌少症与睡眠质量的关联性

Relationship between sarcopenia and sleep quality in elderly women

目的了解老年女性肌少症和睡眠质量,探讨两者之间的相关性。方法选取天津市60~70岁老年女性224人为研究对象,并于2017年9月至11月进行体成分、握力、5次坐立试验、6米步速及睡眠质量检测。肌少症患者26人,非肌少症患者198人。采用独立样本t检验分析不同组别老年女性的各项指标的差异性,采用卡方检验分析老年女性入睡时间等分类指标构成比的差异性,采用二元Logistic回归分析探讨老年女性肌少症与睡眠质量的相关性。结果与正常组相比,肌少症组相对四肢骨骼肌、握力、步速明显较低(P均<0.01),5次坐立试验时间明显较高(P<0.01);与正常组相比,肌少症组睡眠持续时间较低(P<0.01),入睡时间、睡眠障碍发生率较高(P均<0.01);与非睡眠障碍组相比,睡眠障碍组相对四肢骨骼肌、握力、步速较低(P均<0.05),5次坐立试验时间较高(P<0.01);二元Logistic回归分析显示,入睡时间达30~45 min(OR=4.000,P<0.05)、入睡时间>45 min(OR=4.800,P<0.05)、睡眠持续时间<6 h(OR=2.813,P<0.05)、睡眠持续时间>8 h(OR=3.474,P<0.05)、睡眠障碍(OR=2.407,P<0.05)与老年女性肌少症风险的增加有关。结论睡眠障碍、入睡时间以及睡眠持续时间均是影响老年女性肌少症发生的重要因素,睡眠障碍、过长的入睡时间、过长及过短的睡眠持续时间均会增加老年女性肌少症发生的风险。

ObjectiveTo explore the correlation between correlation between scarcopenia and sleep quality in elderly women.Methods 224 elderly women aged 60-70 years in Tianjin were selected as the research objects.Body composition,grip strength,five sit and stand tests,6-meter walking speed and sleep quality were tested from September to November 2017.There were 26 patients with sarcopenia and 198 patients without sarcopenia.Independent sample t-test was used to analyze the differences of various indicators in different groups of elderly women.Chi square test was used to analyze the difference of the constituent ratio of classification indicators such as sleeping time.Binary Logistic regression analysis was used to explore the correlation between sarcopenia and sleep quality in elderly women.Results Compared with the normal group,the relative limb skeletal muscle,grip strength and walking speed of the sarcopenia group were significantly lower(P<0.01),and the time of five sit and stand tests was significantly higher (P<0.01).Compared with the normal group,the duration of sleep in the sarcopenia group was lower(P<0.01).The sleep time and the incidence of sleep disorders were higher in the sarcopenia group(P<0.01);compared with the non sleep disorder group,the relative limb skeletal muscle,grip strength and walking speed of the sleep disorder group were significantly higher(P<0.01).The walking speed was lower(P<0.05),and the time of five sit and stand tests was higher(P<0.01).The binary Logistic regression analysis showed that the time of falling asleep was 30-45 min(OR=4.000,P<0.05),the time of sleeping>45 min(OR=4.800,P<0.05),the duration of sleep<6 h(OR=2.813,P<0.05),and the duration of sleep>8 h(OR=3.474,P<0.05)and sleep disorders(OR=2.407,P<0.05)were associated with an increased risk of sarcopenia in elderly women.ConclusionSleep disorders,sleep time and sleep duration are important factors affecting sarcopenia in elderly women.Sleep disorders,long sleep time,long and short sleep duration will increase the risk of sarcopenia in elderly women.
