We investigated the prevalence and correlates of sleep complaints in a large well-characterized population.
The Atherosclerosis Risk in Communities Study is a prospective population-based study of cardiovascular disease. Using this well-characterized cohort, we undertook a cross-sectional epidemiologic analysis of correlates of 3 sleep complaints that are commonly included in insomnia definitions. We hypothesized that different sleep complaints included under the rubric of "insomnia" would have different correlates. Using multivariate regression analysis we predicted the likelihood of endorsing the symptoms of difficulty falling asleep, difficulty staying asleep, and nonrestorative sleep by age, sex, alcohol intake, smoking, diabetes, heart disease, menopausal status, hypnotic use, hypertension, depression, education level, income, body mass index, respiratory symptoms, and pulmonary function.
North American communities.
13,563 participants aged 47 to 69 years.
None.
The prevalences of sleep complaints were 22%, 39%, and 35% for difficulty falling asleep, difficulty staying asleep, and nonrestorative sleep, respectively. In contrast to previous reports, we found that Black race was associated with reduced risk of sleep complaints. We also found that increasing age was associated with difficulty staying asleep but not with difficulty falling asleep or nonrestorative sleep. Medical illness, depression, lower socioeconomic status, and unhealthy behaviors were associated with increased risk of sleep complaints, which varied by risk factor.
In a well-characterized population-based study, specific sleep complaints have differing covariates. It is likely that difficulty falling asleep and difficulty staying asleep have different causes and outcomes. Sleep difficulties do not appear to be associated with black race per se.
我们在一个特征明确的大规模人群中调查了睡眠问题的患病率及其相关因素。
社区动脉粥样硬化风险研究是一项基于人群的心血管疾病前瞻性研究。利用这个特征明确的队列，我们对失眠定义中通常包含的3种睡眠问题的相关因素进行了横断面流行病学分析。我们假设，“失眠”这一类别下不同的睡眠问题会有不同的相关因素。通过多元回归分析，我们根据年龄、性别、酒精摄入量、吸烟情况、糖尿病、心脏病、绝经状态、催眠药物使用、高血压、抑郁、教育水平、收入、体重指数、呼吸道症状和肺功能，预测了入睡困难、睡眠维持困难和非恢复性睡眠症状出现的可能性。
北美社区。
13563名年龄在47至69岁之间的参与者。
无。
入睡困难、睡眠维持困难和非恢复性睡眠的睡眠问题患病率分别为22%、39%和35%。与之前的报告不同，我们发现黑人种族与睡眠问题风险降低有关。我们还发现，年龄增长与睡眠维持困难有关，但与入睡困难或非恢复性睡眠无关。疾病、抑郁、较低的社会经济地位和不健康行为与睡眠问题风险增加有关，且因风险因素而异。
在一项特征明确的基于人群的研究中，特定的睡眠问题有不同的协变量。入睡困难和睡眠维持困难可能有不同的原因和结果。睡眠困难本身似乎与黑人种族无关。
