Hyperkyphosis is associated with restricted pulmonary function and posture, potentially contributing to poor sleep. A previous study reported older women with hyperkyphosis had worse self-reported sleep quality, but it is less clear if this association exists in men. We examined the association between hyperkyphosis and subjective and objective sleep quality in a cohort of older men.
Longitudinal analysis of data from large cohort of older men participating in the Osteoporotic Fractures in Men Study (MrOS).
Community.
We studied 754 men participants in MrOS who had kyphosis measured during the 3rd clinic visit (2007-2009) and future subjective and objective sleep quality assessed between 2009-2012 (an average of 2.9 years later).
N/A.
To measure kyphosis, 1.7 cm thick wooden blocks were placed under the participant's head to achieve a neutral spine position while lying supine on a DXA table. We collected data on both subjective (Pittsburgh Sleep Quality Index [PSQI], and Epworth Sleepiness Scale [ESS]) and objective (wrist actigraphy: Total Sleep Time [TST], Wake After Sleep Onset [WASO], Sleep Efficiency [SE], Sleep Onset Latency [SOL]; and polysomnography: Apnea Hypopnea Index [AHI]) sleep measurements. Those who required >3 blocks were considered hyperkyphotic (n = 145 or 19.2%).
In unadjusted and multivariable analyses, men with hyperkyphosis did not report having worse self-reported sleep characteristics based on PSQI and ESS. Similarly, there were no significant associations between hyperkyphosis and objective sleep measures. When examined as a continuous predictor (blocks ranging from 0-8), results were no different.
Although we hypothesized that poor posture in those with hyperkyphosis would interfere with sleep, in this sample of older men, worse kyphosis was not associated with self-reported or objectively measured poor sleep quality.
脊柱后凸与肺功能受限和姿势有关，可能导致睡眠质量差。先前的研究报告称，患有脊柱后凸的老年女性自我报告的睡眠质量较差，但男性是否存在这种关联尚不清楚。我们在一个老年男性队列中研究了脊柱后凸与主观和客观睡眠质量之间的关系。
对参加男性骨质疏松性骨折研究（MrOS）的大量老年男性队列数据进行纵向分析。
社区。
我们研究了 MrOS 中的 754 名男性参与者，他们在第三次就诊期间（2007-2009 年）进行了脊柱后凸测量，并在 2009-2012 年期间（平均 2.9 年后）评估了未来的主观和客观睡眠质量。
无。
为了测量脊柱后凸，在参与者仰卧在 DXA 表上时，在其头部下方放置 1.7 厘米厚的木块，以实现中立的脊柱位置。我们收集了主观（匹兹堡睡眠质量指数 [PSQI] 和嗜睡量表 [ESS]）和客观（腕部活动记录仪：总睡眠时间 [TST]、睡眠起始后觉醒 [WASO]、睡眠效率 [SE]、睡眠起始潜伏期 [SOL]；和多导睡眠图：呼吸暂停低通气指数 [AHI]）睡眠测量数据。那些需要 >3 个木块的人被认为是脊柱后凸（n = 145 或 19.2%）。
在未调整和多变量分析中，脊柱后凸的男性报告的 PSQI 和 ESS 自我报告的睡眠特征没有变差。同样，脊柱后凸与客观睡眠测量之间也没有显著关联。当作为连续预测因子（木块范围为 0-8）进行检查时，结果没有差异。
尽管我们假设脊柱后凸患者的不良姿势会干扰睡眠，但在这个老年男性样本中，更严重的脊柱后凸与自我报告或客观测量的睡眠质量差无关。
