目的探讨中国南方社区老年人客观体能水平与睡眠质量的关系。方法对东莞市50岁社区居民1336例（男504例，女632例）进行横断面研究。所有被试均被要求完成所有准备的多工具问卷，包括匹兹堡睡眠质量指数（中文版），用于评估睡眠质量和有关社会人口特征、生活方式和身体健康数据的信息。通过握力、睁眼单腿站立试验（OLST）、背部抓伤试验和用力肺活量（FVC）测量身体健康。结果50岁以上老年人睡眠质量差的比例高达18.2%。较低的FVC与较差的睡眠质量相关（每SD增加调整OR=0.74； P=0.009），在背部抓伤测试中表现较差的参与者更有可能遭受较差的睡眠质量（每SD增加调整OR=1.17； P=0.035）。体质测试结果对睡眠质量差风险的独立贡献为22.1%。结论社区居住老年人睡眠质量与身体素质有显著相关性；身体素质越低，睡眠质量越差。
Purpose The aim of this study was to explore associations between objectively assessed physical fitness levels and sleep quality in community-dwelling elderly people in South China.Methods One thousand one hundred thirty-six (504 males and 632 females) community-dwelling adults aged 50years old in Dongguan City, South China, were included in the cross-sectional study. All the participants were asked to complete all prepared multi-instrument questionnaire, including the Pittsburgh Sleep Quality Index (Chinese version), for the assessment of the sleep quality and information regarding socio-demographic characteristics, lifestyle, and physical health data. Physical fitness was measured by grip strength, one-leg standing test (OLST) with eyes open, back scratch test, and the forced vital capacity (FVC).Results The percentage of poor sleep quality among elderly people (50years old) was up to 18.2%. Lower FVC was associated with the poorer sleep quality (adjusted OR=0.74 per SD increase; P=0.009), and participants with lower performance in back scratch test were more likely to suffer poor sleep quality (adjusted OR=1.17 per SD increase; P=0.035). The independent contribution of physical fitness tests results on the risk of poor sleep quality was 22.1%.Conclusions Our results indicated that sleep quality was strongly associated with physical fitness among community-dwelling elderly people; the lower of the physical fitness predicted poorer sleep quality.
