Sleep disturbance is a complex health problem in ageing global populations decreasing quality of life among many older people. Geographic, cultural, and ethnic differences in sleep patterns have been documented within and between Western and Asian populations. The aim of this study was to explore sleep problems among Hong Kong seniors by examining the prevalence of poor sleep quality, the relationship between sleep quality and health-related quality of life, and associated factors of good sleepers in different age groups.
This cross-sectional study used convenience sampling and gathered data during face-to-face interviews. Older community-dwelling individuals (n = 301) were recruited in community centres in 2010. The Pittsburgh Sleep Quality Index and Medical Outcomes Study Short Form-36 were used to measure sleep quality and health-related quality of life. The Medical Outcomes Study Short Form-36 domain scores were compared between good and bad sleepers and between long and short sleepers using Hotelling's T-Square test. SF-36 domain scores were placed into a logistic regression model that controlled for significant demographic variables (gender, educational level, perceived health).
Most (77.7%) participants were poor sleepers. Participants who had global Pittsburgh Sleep Quality Index scores <5 and slept ≥5.5 h/night had better health-related quality of life. Vitality, emotional role, physical functioning, and bodily pain domain scores were associated factors of good sleepers in different age groups.
This study found a strong negative association between sleep deprivation (poor quality, short duration) and health-related quality of life. Associated factors for good sleep quality in later life differ among age groups in relation to universal age-related changes, and should be addressed by social policies and health-care programmes.
睡眠障碍是一个复杂的健康问题，在全球老龄化人口中，它降低了许多老年人的生活质量。在西方和亚洲人群中，已经记录了睡眠模式在地理、文化和种族方面的差异。本研究旨在通过检查香港老年人睡眠质量差的流行程度、睡眠质量与健康相关生活质量之间的关系以及不同年龄组中睡眠良好者的相关因素，来探讨香港老年人的睡眠问题。
本横断面研究使用便利抽样法，于 2010 年在社区中心进行面对面访谈收集数据。招募了年龄在 65 岁及以上的社区居住的老年人（n=301）。使用匹兹堡睡眠质量指数和医疗结局研究简表 36 来测量睡眠质量和健康相关的生活质量。使用 Hotelling's T 平方检验比较良好和不良睡眠者以及长睡眠者和短睡眠者之间的医疗结局研究简表 36 各领域得分。将医疗结局研究简表 36 各领域得分放入一个逻辑回归模型中，该模型控制了显著的人口统计学变量（性别、教育水平、感知健康）。
大多数（77.7%）参与者为睡眠不良者。匹兹堡睡眠质量指数总分<5 且每晚睡眠≥5.5 小时的参与者具有更好的健康相关生活质量。活力、情感角色、身体功能和躯体疼痛领域得分是不同年龄组良好睡眠者的相关因素。
本研究发现，睡眠剥夺（质量差、时间短）与健康相关生活质量之间存在很强的负相关。晚年良好睡眠质量的相关因素在不同年龄组中因普遍的与年龄相关的变化而有所不同，社会政策和医疗保健计划应针对这些因素。
