ABSTRACT
Objective To explore the prevalence and influencing factors of obstructive sleep apnoea syndrome(OSAS)among hypertensive patients. Methods Two hundred and ninety-eight hypertensive patients who used a portable OSAS monitoring device were selected as our subjects. Of which,197 patients who completed their OSAS monitoring were divided into OSAS group( 165 cases) and non-OSAS group. Stepwise linear regression and Logistic regression analysis were used to analyze the relevant factors correlated to AHI and OSAS with hypertension. Results The average age of the 197 patients(122 were males)were 59. 93 ± 10. 18 years old. The prevalence of OSAS was 83. 8% in hypertension patients. Body mass index( BMI),systolic pressure (SBP),diastolic pressure(DBP),low density lipoprotein cholesterol(LDL-C)and waist circumference in OSAS groups were(26. 37 ± 2. 77)kg/ m2 ,(159. 59 ± 14. 42)mmHg,(98. 71 ± 9. 40)mmHg,(2. 85 ± 0. 82)mmol/L,(90. 56 ± 8. 62)cm,higher than those in non-OSAS group((22. 43 ± 2. 04)kg/ m2 ,(146. 83 ± 4. 60) mmHg,(85. 51 ± 7. 52)mmHg,(2. 22 ± 0. 60)mmol/ l. ,(81. 84 ± 8. 00)cm). There were statistical differences between the two groups(t = - 7. 654,- 4. 945,- 7. 490,- 4. 110 and - 5. 289;P < 0. 001). BMI,SBP and DBP were positively associated with AHI,and they were in depended risk factors of OSAS(OR(95% CI)=2. 554(1. 408 - 4. 632),1. 432(1. 154 - 1. 777),1. 286(1. 058 - 1. 562);P < 0. 05). Conclusion The prevalence of OSAS is high in hypertension patients. Higher BMI,SBP,DBP are associated with OSAS in hypertension pateints.
