研究目的：本研究的目的是检查老年人睡眠中周期性肢体运动 (PLMS) 的自然史。设计：前瞻性、纵向设计。设置：圣地亚哥地区。参与者：社区居住的老年人。干预措施：NA 测量和结果：受试者每隔几年参加一次随访。每次访视时均使用睡眠问卷和夜间睡眠记录评估睡眠障碍。检查了 PLMS 随时间的变化以及与变化相关的变量。尽管样本内存在相当大的变化，但平均 PLMS 并未随时间变化。在女性中，PLMS 的变化与睡眠呼吸障碍的变化相关。在男性中没有发现这种关系。结论：尽管 PLMS 在老年人中的患病率很高，但该疾病的严重程度并不会随着年龄的增长而逐渐恶化。
Study Objectives: The goal of this study was to examine the natural history of periodic limb movements in sleep (PLMS) in older adults.Design: Prospective, longitudinal design.Setting: San Diego area.Participants: Community-dwelling older adults.Interventions: NAMeasurements and Results: Subjects participated in follow-up visits every few years. Sleep disorders were assessed at each visit using sleep questionnaires and overnight sleep recordings. Changes in PLMS over time were examined as well as variables that were associated with change. Average PLMS did not change over time, although there was considerable variability within the sample. In women, changes in PLMS were associated with changes in sleep-disordered breathing. This relationship was not found in men.Conclusions: Although the prevalence of PLMS is high for older adults, the severity of the disorder does not progressively worsen with increasing age.
