Many persons say that they "don't know" whether they snore. The purpose of this study was to investigate the prevalence and correlates of such responses in an elderly population. Subjects were 1715 members (1,155 men, 560 women) of a previously defined cohort (Western Group Collaborative Study) followed prospectively since 1960-1961 with a current mean age of 75.9 (SD = 4.3) for the men and 71.4 (SD = 5.3) for the women. We collected survey questionnaires and reviewed medical records. Results indicated that risk factors for the "don't know" response in this population were similar to those for frequent snoring and included: male sex, higher Body Mass Index, smoking, and use of sinus medication. Between 28 and 44% of the cohort answered questions about snoring with a "don't know" response. These data are compatible with the interpretation that subjects may disavow knowledge of their own snoring and suggest that future studies consider the "don't know" response to questions about snoring as a response of potential interest.
许多人表示他们“不知道”自己是否打鼾。本研究的目的是调查老年人群中此类回答的发生率及其相关因素。研究对象是自1960 - 1961年起前瞻性随访的一个先前定义队列（西部协作组研究）中的1715名成员（1155名男性，560名女性），目前男性的平均年龄为75.9岁（标准差 = 4.3），女性为71.4岁（标准差 = 5.3）。我们收集了调查问卷并查阅了医疗记录。结果表明，该人群中回答“不知道”的危险因素与频繁打鼾的危险因素相似，包括：男性、较高的体重指数、吸烟以及使用鼻窦药物。该队列中有28%至44%的人在回答关于打鼾的问题时选择“不知道”。这些数据支持这样一种解释，即受试者可能否认自己知道自己打鼾，这表明未来的研究应将对打鼾问题回答“不知道”视为一个可能有研究价值的回答。
