体质指数和阻塞性睡眠呼吸暂停低通气综合征的相关性分析

Correlative Analysis of Body Mass Index and Obstructive Sleep Apnea Hypopnea Syndrome

目的:探究人体体质指数和阻塞性睡眠呼吸暂停低通气综合征的相关性。方法:选取2015年3月-2016年3月于我院治疗的阻塞性睡眠呼吸暂停低通气综合征(OSAHS)患者169例,根据患者的体质指数(BMI)分为肥胖组(89例,BMI>24)、非肥胖组(80例,BMI≤24)。调查患者的睡眠呼吸暂停低通气(通气不足)指数(AHI)、呼吸暂停持续时间(AD)、患者呼吸的频率、夜间最低血氧饱和度(LSaO_2)、平均血氧饱和度(MSaO_2)、患者的嗜睡程度评分;患者的颈部、腰臀比、2组患者的OSAHS的严重程度;2组患者的体质指数于阻塞性睡眠呼吸着暂停低通气综合征的相关系数计算。结果:数据分析结果显示,肥胖组患者AHI、AD要明显高于非肥胖组患者(P<0.05);呼吸频率要明显低于非肥胖组患者(P<0.05),肥胖组的患者的夜间LSaO_2、MSaO_2及患者的嗜睡程度评分均远高于非肥胖组(P<0.05)。肥胖组患者的颈围、腰臀比、患者OSAHS的严重程度均明显高于非肥胖组(P<0.05),肥胖组患者OSAHS的中重度患者占60.68%,非肥胖组患者OSAHS的中重度患者占43.75%;相关性分析显示,患者的颈围、腰臀比、BMI数值与AHI呈正相关,LSaO_2与AHI呈负相关。结论:患者的体质指数与AHI呈正相关,患者的体质指数越大,其患病程度会越严重。

Objective： To explore the correlation between body mass index and obstructive sleep apnea hypopnea syndrome. Methods： 169 patients with obstructive sleep apnea hypopnea syndrome（ OSAHS） treated in our hospital from March 2015 to March 2016 were divided into obese group（ 89,BMI 24） according to the body mass index（ BMI）,and Non-obese group（ 80,BMI ≤24）. AHI,duration of apnea（ AD）,frequency of respiratory respiration,minimum nighttime oxygen saturation（ LSaO_2）,mean blood oxygen saturation（ MSaO_2）,and patient＇ s sleep apnea hypopnea were observed. The degree of sleepiness score,the patient＇s neck,waist-to-hip ratio,the severity of OSAHS were also evaluated in both groups. Results： The results of data analysis showed that the AHI and AD in the obese group were significantly higher than those in the non obese group（ P〈 0. 05） and respiratory rate was significantly lower than that in non obese group（ P〈 0. 05）. Nocturnal LSaO_2,MSaO_2 and the degree of sleepiness in Obese patients were much higher than that of the non obese group（ P〈 0. 05）. The severity of obese patients with neck circumference,waist hip ratio,and OSAHS degree were significantly higher than non obese group（ P〈 0. 05）. Obese patients with moderate to severe OSAHS accounted for 60. 68%,and non obese patients with moderate to severe OSAHS accounted for 43. 75%. Correlation analysis showed that the neck circumference,waist to hip ratio and BMI value were positively correlated with AHI,and LSaO_2 was negatively correlated with AHI. Conclusion： The body mass index of patients is positively correlated with AHI,the greater the body mass index of patients,the more serious the degree of illness.
