The study on the association between obstructive sleep apnean-hypopnea syndrome and hypertension in Chengdu and research related factors

Objectives We study the association between obstructive sleep apnea-hypopnea syndrome and hypertension in Chengdu and research related factors just as apnea hypopnea index、body mass index、c-circumstan/height ratio,et al.Methods 350 patients with OSAHS were investigated with questionnaire,and all patients had been monitored at least for 7 hours in the lab.The indexes include apnea hypopnea index、body mass index、c-circumstan/height ratio,et al.Results In the 350 patients with OSAHS,the incidence of hypertension is 27.14 %,and the male is more than the female.The level of AHI index contributes to the incidence of patients with OSAHS and hypertension.The sleep-apnea-hypertensive questionnaire was a facticity and reliable tool.Conclusion In the 350 patients with OSAHS,the incidence of hypertension is 27.14 %.There are statistical correlation between age、AHI、BMI and hypertension.Regression equation: Y=-6.718 +0.818 X1 +1.068 X2 +0.433 X3(1 for age,body weight for 2,3 for AHI),Through the significance test of the regression model and the coefficient,we prove the model significantly efficient.
