高血压遗传因素与胰岛素抵抗

Hypertensive Genetic Factor and Insulin Resistance

  • 摘要: 目的探讨高血压遗传因素与胰岛素抵抗及其他代谢因素的关系。方法采用家系调查方法,共调查高血压家系25个,包括直系亲属158例,其中高血压54例,血压正常者104例;对照家系15个,直系亲属65人。对比分析高血压家系有无高血压及对照家系直系亲属尿酸、血脂、血糖及胰岛素的差异。结果调整年龄、性别后,在高血压家系中无论是否患高血压,甘油三酯(TG)、TG的对数转换值(logTG)、高密度脂蛋白胆固醇(HDLC)、血浆总胆固醇(TC)/HDLC、尿酸、胰岛素(IN)及其对转换值(logIN)均显著高于对照家系,而高血压家系内有无高血压两组比较,除胰岛素、logIN外,其他因素均无显著差别,进一步调整年龄、性别、体重指数后比较,TG、logTG在三组间差异不再显著,尿酸、TC/HDLC、logIN在高血压家系内高血压及血压正常人群间无显著统计学差别,但两者与对照家系相比均显著升高。结论具有高血压遗传因素者无论是否患高血压均有显著的胰岛素抵抗和代谢紊乱,这些代谢异常可能在超重和高血压发生前就已存在。

     

    Abstract: Aim\ To explore the association between genetic factor of hypertension and insulin resistance as well as other metabolic disorders.\ Methods\ 40 pedigrees including 223 direct relatives, 158 individuales(54 hypertensives and 104 normotensives) in 25 hypertension prone pedigrees(HF), 65 individuals in normotensive pedigrees(NF), were recruited from Shijingshan District,Beijing.\ Metabolic factors of members in HF were compared with those in NF.\ Results\ The subjects in HF were divided into hypertensive group(HFH) and normotensive group(HFN).\ No significant difference was found in terms of BMI between HFN and NF group.\ However, after adjustment for age and sex, plasma uric acid(UA),TG,log TG,TC/HDL C, fasting plasma insulin(IN) and log IN were significantly higher in HFH and HFN groups than those in NF, but there were no significant difference between HFH and HFN except for insulin level.\ Further adjusting for age, sex and BMI, only UA, TC/HDL C and log In remained significantly higher in HFH and HFN than in NF, but no significance were found between HFH and HFN groups.\ Conclusion\ These results indicated that all subjects with genetic factor of hypertension, whether high blood pressure has developed or not, tend to have insulin resistance and metabloc disorders,which may precede the onset of established essential hypertension and overweight.
