Objective : To investigate the correlation between obstructive sleep apnea hypopnea syndrome (OSAHS ) and hypertension and its risk factors ,so as to provide basis for prevention and treatment of OSAHS accompanied by hypertension . Methods : A total of 108 OSAHS patients were enrolled and the general conditions were recorded . The blood pressure at 22 ∶ 00 before sleep and that at 8 ∶ 00 . next morning was determined routinely ,and the blood lipid level was detected . According to apnea hypoapnea index (AHI) ,the patients were divided into three groups ,the mild group (5/h ≤ AHI < 15/h) with 31 cases ,the moderate group (15/h ≤ AHI < 40/h) with 36 cases ,and the severe group (AHI ≥ 40 /h) with 41 cases . The levels of blood pressure were compared among the groups . According to whether OSAHS was accompanied by hypertension ,the patients were divided into simple OSAHS group and OSAHS accompanied by hypertension group . The relevant factors associated with OSAHS accompanied by hypertension were screened out by single factor analysis ,and then the multiple Logistic regression analysis was conducted .Results : (1)Among 108 patients with OSAHS ,60 cases(55 .6% ) were accompanied by hypertension ,including 15 cases of mild group(48 .4% ,15/31) ,19 cases of moderate group (52 .8% ,19/36) ,and 26 cases of severe group (63 .4% ,26/41 ) . There was no significant difference regarding the prevalence rate of hypertension among the three groups (P > 0 .05) .There were significant differences regarding systolic blood pressure(SBP) and diastolic blood pressure (DBP) at 22 ∶ 00 and 8 ∶ 00 among the three groups (P < 0 .05) ;SBP and DBP at 22 ∶ 00 and 8 ∶ 00 in severe group were significantly higher than those in mild group (P< 0 .05) .SBP at 22 ∶ 00 and 8 ∶ 00 in severe group was significantly higher than that in moderate group (P< 0 .05) .(2) Single factor analysis showed that age ,body mass index (BMI) ,smoking rate ,abdominal circumference ,AHI ,total cholesterol(TC) ,triglyceride(TG ) and low density lipoprotein cholesterol (LDL-C) in OSAHS accompanied by hypertension group were significantly higher than those in simple OSAHS group ,while HDL-C was significantly lower than that in simple OSAHS group ( P < 0 .05 ) . (3 ) Multivariate Logistic regression analysis showed that BMI ,AHI ,TC were the risk factors for OSAHS accompanied by hypertension .Conclusions :The level of blood pressure in patients with OSAHS was accordance with the disease severity ,while BMI ,AHI ,TC were the risk factors for OSAHS accompanied by hypertension .%目的：探讨阻塞性睡眠呼吸暂停低通气综合征（OSAHS）与高血压的关系及其危险因素，为预防和治疗 OSAHS 合并高血压提供依据。方法：选择 OSAHS 患者共108例，记录一般情况，测定患者22∶00和8∶00的血压，检测血脂水平。根据呼吸暂停低通气指数（AHI）将108例患者分为3组。轻度组：5次／h ≤ AHI ＜15次／h ，31例；中度组：15次／h ≤ AHI ＜40次／h ，36例；重度组：AHI ≥40次／h ，41例。比较各组的血压水平。根据 OSAHS 患者是否合并高血压，将患者分为单纯 OSAHS组及 OSAHS 合并高血压组。通过单因素分析筛选与 OSAHS 合并高血压相关的因素，然后进行 Logistic 多因素回归分析。结果：（1）108例 OSAHS 患者中合并高血压60例（55．6％），其中轻度组15例（48．4％，15／31），中度组19例（52．8％，19／36），重度组26例（63．4％，26／41）；3组间高血压的患病率差异无统计学意义（P ＞0．05） 。 3组间22∶00和8∶00的收缩压（SBP）、舒张压（DBP）比较，差异均有统计学意义（P＜0．05）。重度组22∶00和8∶00 SBP 、DBP 明显高于轻度组（P＜0．05），重度组22∶00和8∶00 SBP 明显高于中度组（P＜0．05）。（2）单因素分析结果显示，OSAHS 合并高血压组的年龄、体质量指数（BMI）、吸烟率、腹围、AHI 、总胆固醇（TC）、三酰甘油（TG）及低密度脂蛋白胆固醇（LDL-C）均高于单纯 OSAHS 组（P ＜0．05），而高密度脂蛋白胆固醇（HDL-C）低于单纯 OSAHS 组（ P＜0．05）。（3）多因素 Logistic 回归结果显示，BMI 、AHI 、TC为 OSAHS 合并高血压的危险因素。结论： OSAHS 患者高血压的水平与其病情严重程度具有一致性，而 BMI 、AHI 、TC 为OSAHS 合并高血压的危险因素。
