AbstractObjective：Tocomparetheclinicaldataand major sleep monitoring indexes ofobese andnon-obeseobstructive sleep apnea（OSA）patients，andtofurther explore thecharacteristicsofobeseOSApatients.Methods：Atotalof235patientswhocompleted polysomnographyexaminationattheSleepCentreofteDepartmentoftorhinolarygology，HeadandNckSugery，uling HospitalandclearlydiagnosedwithOSA wereselectedasthestudysubjects.Theclinical informationof hepatients，includingthe general informationand majorslepparameters werecolected.OSApatients were divided intonon-obese groupandobesegroup according tobodymassindex（BMI）.Thediferences inclinical informationandmajorsleepdetectionparametersbetweenthe two groups werecompared，andthecorelationbetweenBMandmajorsleepparameters wasanalysedResults：1）Te minmublood oxygen（ LSaO2 ） and mean blood oxygen（ MSaO2 ） of OSA patients in the obese group were significantly lower than those in the non-obese group（ P<0.05 ），and the apnea hypoventilation index（AHI） of OSA patients in the obese group was significantly higher than that of the non-obese group（ P<0.05）.2 The percentage of non-rapid eye movement（REM） sleep stage I（N1） in OSA patients in the obese group was significantly higher than that in the non-obese group（ P<0.05 ），and the percentage of nonrapid eye movement（N3）sleep stageI（N3）inOSA patients intheobese group wassignificantlylowerthanthat inthe non-obese group（ P<0.05 ）. 3）Spearman correlation analysis showed that BMI was positively correlated with AHI（ r=0.5，P<0.05 ）and negatively correlated with LSaO2 and N3 stage occupancy（ r=-0.5，-0.2，P<0.05 ）. Conclusion：BMI of OSA patients was positivelycorelatedwithtedegreeofnocturnalhypoxiaandnegativelycorrelatedwiththepercentageofdeepslp，suggesting that obesity exacerbates the degree of nocturnal hypoxia and deep sleep deprivation in OSA patients.

阻塞性睡眠呼吸暂停（Obstructive Sleep Apnea，OSA）是指睡眠状态下上气道反复塌陷阻塞所引发的呼吸暂停及低通气，导致患者睡眠结构紊乱、血氧水平频繁下降，可增加高血压、心脑血管疾病、2型糖尿病、代谢综合征的发病风险，甚至发生夜间猝死，严重影响生命质量及危害公众健康[1]。（剩余7802字）
