血压正常高值者腹内脂肪现状及相关影响因素分析

Impact of visceral fat on metabolic profiles in patients with prehypertension

目的研究正常高值血压者腹内脂肪情况及相关因素。方法 B超测量122例正常血压者、180例正常高值血压者和84例高血压者的腹内脂肪厚度,同时测量腰围、计算体重指数(BMI),检测检测空腹血糖(FBG)、总胆固醇(TC)、三酰甘油(TG)、高密度脂蛋白胆固醇(HDL-C)和低密度脂蛋白胆固醇(LDL-C)指标。结果 FBG、TC、TG、LDL-C、BMI在正常血压组、正常高值血压组及高血压组逐渐升高,HDL-C则逐渐降低,组间比较差异均有统计学意义(P<0.05);三组之间腰围、腰臀比差异无统计学意义(P>0.05),腹内脂肪厚度在正常血压组、正常高值血压组及高血压组逐渐升高,组间比较差异均有统计学意义(P<0.05);相关分析显示,腹内脂肪厚度与FBG、TC、TG及LDL-C呈正相关(P<0.01)。结论血压正常高值者其腹内脂肪厚度明显增加,血糖、血脂异常较为明显。

Objective To explore the changes of visceral fat thickness in prehypertensive patients and investigate the related factors of visceral fat thickness. Methods 122 cases normotensive,180 case prehypertensive and 84 cases hypertensive were selected to test visceral fat thickness,waistline,BMI,blood glucose and blood lipid. Results FBG,TC,TG,LDL- C and BMI gradually increased in the normotensive group,prehypertensive group and hypertensive group. However,the difference among the groups was statistically significant（ P〈0. 05）. The waistline did not show significant difference among three groups（ P〈0. 05）. There was significant visceral fat thickness among three groups,the hypertensive group was the thickest and the normotensive group was the slimmest（ P〈0. 05）. The correlation analysis showed that,FBG,TC,TG and LDL- C had positive relationship with visceral fat thickness（ P〈0. 01）. Conclusion Visceral fat thickness in the patients with prehypertension is obviously larger than that in the patients with optimal blood pressure,the abnormality of blood fat and blood sugar are severe.
