The relationship between the severity of obstructive sleep apnea syndrome (OSAS) and both snoring intensity and rate measured objectively has not been sufficiently investigated. The aim of this study was to evaluate the relationship between severity of OSAS and snoring parameters including snoring intensity and rate.
A total of 150 records of individuals who complained of snoring were analyzed. Patients were classified into four groups according to apnea-hypopnea index (AHI). Polygraphy recordings including the snoring intensity and the snoring rate (defined as the percentage of snoring time during the total sleep time) and the clinical data were compared and analyzed.
AHI was significantly correlated, respectively, with snoring rate (r = 0.341; P < 0.0001) and maximal intensity of snoring (r = 0.362; P < 0.0001). However, no correlation was found between the average intensity of snoring and AHI (P = 0.33). When assessing each respiratory event individually, snoring rate was more correlated with hypopnea index (r = 0.424; P < 0.0001) than with AI (r = 0.233; P = 0.004). The snoring rate (%) in the severe OSAS group (31.79 ± 19.3) was significantly higher than that in the mild OSAS group (18.02 ± 17; P = 0.001) and the control group (17 ± 16.57; P = 0.011). Similarly, the maximal intensity of snoring (db) in the severe OSAS group (90.45 ± 13.79) was higher than that in the mild OSAS group (86.46 ± 15.07; P = 0.006) and the control group (84.75 ± 6.65; P < 0.001).
The snoring rate and maximal intensity of snoring correlate better with the severity of OSAS than average snoring intensity.
阻塞性睡眠呼吸暂停综合征（OSAS）的严重程度与客观测量的打鼾强度和频率之间的关系尚未得到充分研究。本研究的目的是评估OSAS严重程度与打鼾参数（包括打鼾强度和频率）之间的关系。
共分析了150例主诉打鼾患者的记录。根据呼吸暂停低通气指数（AHI）将患者分为四组。比较并分析包括打鼾强度和打鼾频率（定义为打鼾时间占总睡眠时间的百分比）的多导睡眠图记录以及临床数据。
AHI分别与打鼾频率（r = 0.341；P < 0.0001）和最大打鼾强度（r = 0.362；P < 0.0001）显著相关。然而，未发现平均打鼾强度与AHI之间存在相关性（P = 0.33）。单独评估每个呼吸事件时，打鼾频率与低通气指数（r = 0.424；P < 0.0001）的相关性高于与呼吸暂停指数（r = 0.233；P = 0.004）的相关性。重度OSAS组的打鼾频率（%）（31.79 ± 19.3）显著高于轻度OSAS组（18.02 ± 17；P = 0.001）和对照组（17 ± 16.57；P = 0.011）。同样，重度OSAS组的最大打鼾强度（分贝）（90.45 ± 13.79）高于轻度OSAS组（86.46 ± 15.07；P = 0.006）和对照组（84.75 ± 6.65；P < 0.001）。
与平均打鼾强度相比，打鼾频率和最大打鼾强度与OSAS严重程度的相关性更好。
