体质量指数和阻塞性睡眠呼吸暂停低通气综合征的相关性研究

Study on correlation between body mass index and obstructive sleep apnea hypopnea syndrome

目的探讨体质量指数(BMI)与阻塞性睡眠呼吸暂停低通气综合征(OSAHS)的关系,分析BMI对OSAHS发生的预测价值。方法选取2017年3-12月大连大学附属中山医院耳鼻喉科OSAHS患者161例,非OSAHS患者51例,一般资料调查表于监测前完成,包括性别、年龄、身高、体质量、学历水平等,临床医生根据多导睡眠图(PSG)监测结果确诊OSAHS。患者需在睡眠监测室监测多导睡眠图,一般监测开始时间为21:00~23:00,结束时间次日晨6:00~7:00,至少监测7 h。结果OSAHS组BMI明显高于非OSAHS组;BMI与OSAHS呈正相关(r=0.501,P<0.01);ROC曲线分析BMI预测发生OSAHS风险的曲线下面积为0.640,P<0.01,95%CI(0.556~0.725)。结论BMI与OSAHS呈正相关,BMI可作为预测OSAHS的有效指标,可为医护人员采取相应干预策略提供参考。

Objective To explore the relationship between the body mass index(BMI)and obstructive sleep apnea hypopnea syndrome(OSAHS),and to analyze the predictive value of BMI to OSAHS occurrence.Methods One hundred and sixty-one cases of OSAHS and 51 cases of non-OSAHS in the otolaryngology department of the Affiliated Zhongshan Hospital of Dalian University from March to December 2017 were selected,the general information questionnaire was completed prior to the monitoring,including the gender,age,height,body mass,education level,etc.,the clinicians definitely diagnosed OSAHS according to the polysomnograph(PSG)monitoring results,the patients needed to monitor PSG in the sleep monitoring room,the general monitoring start time was 21:00-23:00,the end time was 6:00-7:00 at the next morning,and the monitoring time was at least 7 h.Results BMI of the OSAHS group was significantly higher than that of the non-OSAHS group;BMI was positively correlated with OSAHS(r=0.501,P<0.01).The area under the receiver operating curve(ROC)for BMI predicting OSAHS occurrence risk was 0.640,P<0.01,and 95%CI(0.556-0.725).Conclusion BMI is positively correlated with OSAHS,and BMI can serve as an effective index to predict OSAHS,and provide reference for medical workers to adopt corresponding intervention strategies.
