The purpose of this study was to determine if reported nighttime sleep problems and daytime sleepiness were associated with reported falling during the previous 12 months in a representatively sampled older adult population.
Random-digit dial telephone survey.
Representatively sampled older adult population living in northern California.
Participants were 971 women and 555 men, aged 64 to 99 years.
Twenty-minute telephone interview adapted from the National Health Interview Survey.
Two hundred and eighty-four participants reported falling during the previous 12 months (19% of the sample). Significantly more women fell than men (20% and 14%, respectively, P < .001). The following variables were significant risk factors for falling in univariate analyses: female gender, being unmarried, living alone, income less than $15,000 per year, difficulty walking, having more than one chronic medical condition, history of cardiovascular disease, hypertension, arthritis, sensory impairment, psychological difficulties, and nighttime sleep problems. All of the nighttime sleep problem variables remained significant risk factors for falling after controlling for other risk factors for falling.
The results provide support for an independent association between reported sleep problems and falls in an older population. One of the implications of these data is that behavioral research focusing on the effectiveness of insomnia treatment in old age should not only examine typical sleep-related outcomes (e.g., total time asleep, number of awakenings) but also the occurrence of falls as well.
本研究旨在确定在具有代表性的老年人群样本中，所报告的夜间睡眠问题和日间嗜睡是否与过去12个月内所报告的跌倒有关。
随机数字拨号电话调查。
居住在加利福尼亚北部的具有代表性的老年人群样本。
971名女性和555名男性，年龄在64至99岁之间。
根据国家健康访谈调查改编的20分钟电话访谈。
284名参与者报告在过去12个月内有跌倒经历（占样本的19%）。女性跌倒的比例显著高于男性（分别为20%和14%，P < .001）。在单因素分析中，以下变量是跌倒的显著危险因素：女性、未婚、独居、年收入低于15000美元、行走困难、患有不止一种慢性疾病、有心血管疾病史、高血压、关节炎、感觉障碍、心理问题以及夜间睡眠问题。在控制了其他跌倒危险因素后，所有夜间睡眠问题变量仍然是跌倒的显著危险因素。
研究结果支持了在老年人群中所报告的睡眠问题与跌倒之间存在独立关联。这些数据的一个启示是，关注老年失眠治疗效果的行为研究不仅应检查典型的睡眠相关结果（如总睡眠时间、觉醒次数），还应检查跌倒的发生率。
