高血压患者体重指数与脂肪肝相关性探讨

目的　探讨高血压患者体重指数与脂肪肝、血脂及血压之间的关系。方法　对 13 5例高血压患者按体重指数(BMI)分为 3组 :正常体重组 (BMI=2 0～ 2 3 ) ,超重组 (BMI=2 4～ 2 7) ,肥胖组 (BMI≥ 2 8) ,所有患者均测血脂、血压 ,并行腹部 B超检查。结果　肥胖组较正常组总胆固醇 (TC)、三酰甘油 (TG)、低密度脂蛋白 (L DL )有明显差异(P<0 .0 5 ) ;肥胖组与超重组比较 ,仅 TC有差异 (P<0 .0 5 )。 BMI与脂肪肝的发生率呈正相关 (rs=0 .911,P<0 .0 1) ,且肥胖组中中、重度脂肪肝的发生率较正常组明显增多 (P<0 .0 1)。收缩压 (SBP)及舒张压 (DBP)均随着BMI的增加而明显增高 :肥胖组高于超重组 ,超重组高于正常组 ,差异有显著性 (P<0 .0 0 1及 P<0 .0 5 )。结论　合并超重的高血压患者应积极减重 ,并控制在正常范围 ,对降低血压、预防冠心病及脂肪肝均有重要意义

Relationship between body mass index and fat liver in patients with hypertension

Objective To study the relation of body mass index(BMI) with fat liver, lipid and blood pressure in patients with hypertension. Methods According BMI,135 patients with hypertension were divided into three groups: normal group(BMI=20~23),overweight group(BMI=24~27), and obesity group(BMI≥28). Serum lipid level and blood pressure were detected and abdominal examination by ultrasound was made in all patients.Results There were difference between obesity group and normal group in TC,TG and LDL ( P <0.05);there was difference between obesity group and overweight group only in TC( P <0.05). There were positive correlation between the incidence of fat liver and BMI( r s=0.911, P <0.01),and the incidence of middle and severe fat liver in obesity group were more than that in the normal group( P <0.01). Systolic blood pressure (SBP) and diastolic blood pressure (DBP) were increased along with the increasing of BMI: SBP and DBP in obesity group were higher than those in overweight group, and those in overweight group were higher than those in normal group( P <0.001 and P <0.05).Conclusion Overweight patients with hypertension should be recommended to lose body weight and control to normal range. This is of great importance in prevention of coronary heart disease,fat liver and reducing blood pressure.
