The aims of this study are to determine the prevalence of position dependency in non-apneic snorers, as defined by the American Academy of Sleep Medicine (AASM) guidelines, and to investigate the influence of various factors such as BMI, neck circumference, age, gender, and sleep efficiency on sleeping position. A cohort of consecutive patients was screened for complaints of excessive snoring or symptoms suspicious for sleep disordered breathing. Overnight polysomnographic data were collected and non-apneic snorers who met all the inclusion criteria were selected for statistical analysis. To assess position-dependent snoring, the snore index (total snores/h) was used. Supine-dependent patients were defined as having a supine snore index higher than their total non-supine snore index. 76 patients were eligible for statistical analysis. Prevalence of position dependency in non-apneic snorers was 65.8% (p < 0.008). A stepwise regression showed that only BMI had a significant effect (p < 0.003) on the supine snore index. This is the first study that uses the AASM guidelines to accurately define non-apneic snorers (AHI < 5) and provides scientific evidence that the majority of non-apneic snorers are supine dependent. Furthermore, these results show that non-apneic snorers with a higher BMI snore more frequently in supine position. The use of sleep position therapy therefore, has the potential to play a significant role in improving snoring and its associated physical and psychosocial health outcomes in this population.
本研究旨在确定非呼吸暂停性打鼾者（根据美国睡眠医学学会[American Academy of Sleep Medicine, AASM]指南定义）中体位依赖性的患病率，并研究 BMI、颈围、年龄、性别和睡眠效率等各种因素对睡眠体位的影响。连续筛查了一批有打鼾过多或疑似睡眠呼吸障碍症状的患者。收集了整夜多导睡眠图数据，并选择符合所有纳入标准的非呼吸暂停性打鼾者进行统计分析。为了评估体位依赖性打鼾，使用了打鼾指数（总打鼾次数/小时）。仰卧位依赖性患者定义为仰卧位打鼾指数高于总非仰卧位打鼾指数。76 名患者符合统计分析条件。非呼吸暂停性打鼾者中体位依赖性的患病率为 65.8%（p<0.008）。逐步回归显示，只有 BMI 对仰卧位打鼾指数有显著影响（p<0.003）。这是第一项使用 AASM 指南准确定义非呼吸暂停性打鼾者（AHI<5）的研究，并提供了科学证据，表明大多数非呼吸暂停性打鼾者为仰卧位依赖性。此外，这些结果表明，BMI 较高的非呼吸暂停性打鼾者在仰卧位时更频繁地打鼾。因此，睡眠体位疗法有可能在改善该人群的打鼾及其相关的身体和心理社会健康结果方面发挥重要作用。
