{Abstract}: Objective: To analyze the relationship between renin-angiotensin-aldosterone system (RAAS) gene polymorphisms and susceptibility to essential hypertension (EH) in military secret service personnel. Methods: In October 2019, military secret service personnel (162 people) who were recuperating in a sanatorium from January to December 2017 were selected as the research subjects, all of whom were Han and male. The patients (79 people) who were diagnosed with EH according to the diagnostic criteria of hypertension in the "Chinese Guidelines for the Prevention and Treatment of Hypertension" (2016 Revised Edition) were the case group, and the people with normal blood pressure (83 people) were the control group. Occupational epidemiological investigation was conducted, 5 ml of fasting cubital venous blood was collected, genomic DNA was extracted by phenol-chloroform method, and RAAS gene polymorphism was detected by polymerase chain reaction-restriction fragment length polymorphism method. The distribution differences of genotype and allele frequency between groups were compared, and the relationship between genotype, allele frequency and EH was analyzed. Results: The average age of military secret service personnel was (38.2±5.3) years old, and there was no statistical significance in the average age and the age distribution over 40 years old of the case group and the control group (P>0.05) . There were significant differences in the distribution of AGT gene M235T locus, ACE gene I/D polymorphism genotype and allele between the case group and the control group (P<0.05) . The TT genotype with AGT gene M235T locus (OR=3.28, 95%CI: 1.21-8.91) and DD genotype with ACE gene (OR=2.86, 95%CI: 1.17-7.00) were risk factors for EH in military secret service personnel. Conclusion: The TT genotype of AGT gene M235T and the DD genotype of ACE gene may be the susceptibility genotypes of military secret service personnel for EH.<BR>目的： 分析军事特勤人员肾素-血管紧张素-醛固酮系统（renin-angiotensin-aldosterone system，RAAS）基因多态性与原发性高血压（essential hypertension，EH）易感性的关系。 方法： 于2019年10月，选择在2017年1至12月某疗养院疗养的军事特勤人员（162人）为研究对象，均为汉族、男性；根据《中国高血压防治指南》（2016年修订版）中高血压诊断标准确诊为EH者（79人）为病例组，血压正常者（83人）为对照组，对其进行职业流行病学调查，并收集空腹肘静脉血5 ml，以酚氯仿法提取基因组DNA，采用聚合酶链反应-限制性片段长度多态性方法检测RAAS基因多态性。比较组间的基因型、等位基因频率的分布差异，分析基因型、等位基因频率与EH的关系。 结果： 军事特勤人员平均年龄（38.2±5.3）岁，病例组和对照组平均年龄及40岁以上年龄分布差异均无统计学意义（P>0.05）。AGT基因M235T位点、ACE基因I/D多态性基因型和等位基因在病例组和对照组的分布差异均有统计学意义（P<0.05）；携带AGT基因M235T位点TT基因型（OR=3.28，95%CI：1.21~8.91）和携带ACE基因DD基因型（OR=2.86，95%CI：1.17~7.00）是军事特勤人员发生EH的危险因素。 结论： AGT基因M235T位点TT基因型、ACE基因DD基因型可能是军事特勤人员EH的易感基因型。.
