Analysis of the clinicl characteristics in 148 patients with snoring and obstructive sleep apnea hypopnea syndrome / 复旦学报（医学版）

ABSTRACT

Objective To investigate the possible correlation of the clinical parameters, such as age, obesity, Epworth sleepiness score (ESS), with the severity of snoring and obstructive sleep apnea hypopnea syndrome (OSAHS). Methods One hundred and forty-eight patients with snoring during sleep admitted from May to Jul. 2008 were asked to answer the questions from a questionnaire concerning snoring, daytime sleepiness, and habits such as smoking and drinking, etc. All patients underwent at least a polysomnography (PSG) and the physical examination included height, weight, and body mass index (BMI). Age, BMI, the lowest SaO_2(%), ESS score, the biggest reduction of oxygen (%), a total suspension of time, the average correlation between respiratory disorder index (RDI) applied computing Pearson correlation test. Simple snoring and OSAHS group of mild, moderate and severe inter-group comparison analysis using generalized linear models. Results The prevalence of OSAHS was increased with age, higher in males than in females. A statistically significant correlation between ESS, BMI, the lowest SaO_2 with the RDI was detected. The difference of ESS, the lowest SaO_2 and the BMI was significant between the different serious patients (P<0.05). Conclusions OSAHS has a high morbidity rate in outpatients with snoring. Age and obesity are liability factors of OSAHS. BMI, the lowest SaO_2, ESS and RDI have well correlationship, which can be used to assess the pathogenetic condition, even make a primary diagnosis.
