지역사회에 거주하는 60세 이상 노인에서 수면 중사지운동과 야간 수면 변인의 연관성

초록

Objectives The aim of this study was to examine the differences in subjective sleep qualityand objective sleep parameters between groups with different severities of limb movements duringsleep in elderly persons with sleep complaints. Methods We recruited adult subjects with sleep complaints from four areas in Gangwon-do. Nocturnal polysomnography studies were conducted for 159 subjects at Kangwon National UniversityHospital. A total of 72 subjects older than 60 years were finally selected, and we classifiedthem into three groups according to the limb movement index (LMI) : 29 subjects with LMI below15, 21 subjects with LMI between 15 and 44, and 22 subjects with LMI above 44. Results The proportion of existing restless legs syndrome (RLS) symptoms differed betweenthe three groups, but was not statistically significant (p=0.051). No difference in nocturnal sleepparameters was observed between the three groups. In the total group, the limb movementarousal index showed positive correlation with respiratory arousal index (r=0.252, p<0.05). Conclusion In elderly persons with sleep complaints, a greater LMI severity was associated witha tendency of higher comorbidity of RLS. Frequent arousals due to limb movements were not associatedwith a greater severity of limb movements during sleep severity, but with increased arousalsdue to respiratory events.
