Application of body component analyzer in the screening of obstructive sleep apnea-related hypertension
Objective:To investigate the body component in patients with obstructive sleep apnea(OSA)-related hyper-tension and primary hypertension by using body component analyzer,and explore its relationship with apnea-hypopnea index(AHI).Methods:A total of 154 patients with OSA-related hypertension(mild,n=48;moderate,n=54;severe,n=52)and 51 patients with primary hypertension were selected as the research objects.Body component analyzer was used to measure the human component data.Results:Patients with OSA-related hypertension had higher body mass index,percent-age body fat,visceral fat area(VFA),waistline,and arm circumference than patients with primary hypertension(all P＜0.05).The VFA(r=0.726)and waistline(r=0.630)were strongly and positively correlated with AHI(all P＜0.01).The sensitivity and specificity of VFA＞91.10 cm2 for screening OSA-related hypertension were 61.7％and 82.4％respec-tively.The sensitivity and specificity of waistline＞88.7 cm for screening OSA-related hypertension were 62.3％and 78.4％respectively.The combined predictor constructed by Logistic was-3.152+0.038 × VFA+0.011 x waistline,which showed sensitivity was 82.1％,specificity was 67.5％,cutoff value was 1.105,and the area under ROC curve was 0.795.The diagnostic efficiency of combined predictor was better than that of single index prediction.Conclusion:Abdomi-nal obesity is a high risk factor of OSA-related hypertension.By using body component analyzer,the combination of VFA and waistline is of great significance for early screening the high-risk population of OSA-related hypertension.
