Although insomnia is a frequent complaint among patients, epidemiologic study has been limited. Researchers have reported a wide range in the prevalence of this complaint in a variety of selected populations. Other parameters, such as incidence and remission rates, have not been reported.
Subjects of the Tucson (Ariz) Epidemiologic Study of Obstructive Lung Disease were asked questions about trouble sleeping in the 1984-1985 (survey I) and 1990-1992 (survey II) surveys. Answers were analyzed along with responses to questions about age, sex, respiratory symptoms, and drug and alcohol use for sleep.
The prevalence of insomnia was similar in both surveys, 34.4% in survey I and 34.1% in survey II. Women had a higher prevalence of insomnia than men in both surveys, and insomnia was more common among older subjects (50.6% of the women aged 65 years or older had insomnia in survey II). In addition, the incidence of new insomnia in survey II was higher in the same groups. Grouping subjects by respiratory symptoms, we found that the prevalence of insomnia was significantly related to cough, dyspnea, or wheeze. Furthermore, subjects with persistent or new respiratory symptoms at survey II were less likely to have remission of insomnia by that survey (31.6% vs 51.5%; P < .05; odds ratio, 0.43) and more likely to develop new insomnia (28.6% vs 14.5%; P < 05; odds ratio, 2.36) than subjects with either no symptoms or disappearance of their symptoms by survey II.
In our population, insomnia is a common dynamic complaint whose frequency waxes and wanes in association with respiratory symptoms.
尽管失眠是患者中常见的主诉，但流行病学研究一直有限。研究人员报告了在各种选定人群中该主诉的患病率范围广泛。其他参数，如发病率和缓解率，尚未见报道。
在图森（亚利桑那州）阻塞性肺病流行病学研究中，对受试者在1984 - 1985年（调查I）和1990 - 1992年（调查II）的调查中关于睡眠问题进行了询问。对答案进行了分析，并结合了关于年龄、性别、呼吸道症状以及用于睡眠的药物和酒精使用情况的问题回答。
两次调查中失眠的患病率相似，调查I为34.4%，调查II为34.1%。在两次调查中，女性失眠的患病率均高于男性，且失眠在老年受试者中更为常见（在调查II中，65岁及以上女性中有50.6%患有失眠）。此外，调查II中新发失眠的发病率在相同人群中更高。按呼吸道症状对受试者进行分组，我们发现失眠的患病率与咳嗽、呼吸困难或喘息显著相关。此外，在调查II中有持续性或新发呼吸道症状的受试者在该调查中失眠缓解的可能性较小（31.6%对51.5%；P <.05；优势比，0.43），并且比在调查II中无症状或症状消失的受试者更有可能出现新发失眠（28.6%对14.5%；P < 05；优势比，2.36）。
在我们的人群中，失眠是一种常见的动态主诉，其频率与呼吸道症状相关而有波动。
