Currently, the data for effect of sleep on falls-associated fractures in elderly individuals are still limited. This current study was aimed to assess the link between self-reported sleep characteristics and falls-associated fractures in elderly individuals. This study included a total of 20,497 participants from National Health and Nutritional Examination Survey (NHANES) 2005-2008, and 6,174 participants aged 45 years and older were identified. Self-reported sleep characteristics and conditions of falls-associated fractures of individuals were obtained via the method of personal questionnaires. In a total of 610 participants with exact history of fractures, 168 individuals with falls-associated fractures were identified, and the prevalence was 27.5%. The mean age of falls-associated fractures group was (72.1 ± 8.8) years, and the female ( < 0.001) occupied a higher proportion. Factors of living alone ( = 0.003), combined with hypertension ( = 0.003) and osteoporosis ( < 0.001), sleeping less or more ( = 0.009), and frequent snoring ( = 0.007) were linked to falls-associated fractures. Compared with sleep duration of 6 to 8 h/night, sleep duration of ≤4 h/night (odds ratio [OR] 1.858, 95% confidence interval [CI] 1.115-3.094) and of ≥9 h/night (OR 1.932, 95% CI 1.195-3.123) were related to an increased risk of falls-associated fractures. Collectively, our nationwide data noted that sleep characteristics were closely related to falls-associated fractures in elderly individuals, and a longer sleep duration may exhibit a protective effect against the falls-associated fractures, but it should be limited within 9 h/night.
目前，关于睡眠对老年人跌倒相关骨折影响的数据仍然有限。本研究旨在评估老年人自我报告的睡眠特征与跌倒相关骨折之间的联系。该研究纳入了2005 - 2008年美国国家健康与营养检查调查（NHANES）的总共20497名参与者，其中确定了6174名年龄在45岁及以上的参与者。通过个人问卷调查的方法获取了个体自我报告的睡眠特征和跌倒相关骨折情况。在总共610名有确切骨折病史的参与者中，确定了168名跌倒相关骨折患者，患病率为27.5%。跌倒相关骨折组的平均年龄为（72.1±8.8）岁，女性占比更高（<0.001）。独居因素（=0.003）、合并高血压（=0.003）和骨质疏松（<0.001）、睡眠过少或过多（=0.009）以及频繁打鼾（=0.007）与跌倒相关骨折有关。与每晚睡眠时长6至8小时相比，每晚睡眠时长≤4小时（优势比[OR]1.858，95%置信区间[CI]1.115 - 3.094）和≥9小时（OR 1.932，95%CI 1.195 - 3.123）与跌倒相关骨折风险增加相关。总体而言，我们的全国性数据表明，睡眠特征与老年人跌倒相关骨折密切相关，较长的睡眠时长可能对跌倒相关骨折具有保护作用，但应限制在每晚9小时以内。
