正常高值血压飞行人员心血管危险因素调查分析

Analysis of cardiovascular risk factors in flying personnel with high normal blood pressure

目的 探讨正常高值血压飞行人员心血管危险因素存在情况,为预防心血管疾病的发生提供参考依据.方法 根据血压水平,将391名飞行人员分为正常血压组及正常高值血压组,并将两组人员的体质指数（body mass index,BMI）、血清总胆固醇（total cholesterol,TC）、甘油三酯（triglyceride,TG）、高密度脂蛋白（high density lipoprotein,HDL）、低密度脂蛋白（low density lipoprotein,LDL）、血尿酸（uric acid,UA）等指标进行比较,且调查其吸烟情况及心血管疾病家族史.结果 常高值血压组飞行人员BMI、TG、LDL水平及血脂异常患病率均显著高于正常组（r=2．023、2．191、2．336,P＜0．05;χ2=7．535,P＜0．05）,两组间UA、TC、HDL水平、吸烟率及心血管疾病家族史阳性率无明显差异. 结论 正常高值血压组飞行人员较正常血压组存在更多的心血管危险因素,应注重对这部分人群可控危险因素的干预.

Objective To investigate the epidemic features of cardiovascular risk factors in the flying personnel with high normal blood pressure （BP）. Methods Three hundred and ninety-one flying personnel were divided into normal BP group and high normal BP group by judging if the systolic and diastolic BP was higher than 120 and 80 mm Hg respectively. Body mass index （BMI）, serum total cholesterol （TC）, triglyceride （TG）, high density lipoprotein （HDL）, low density lipoprotein （LDL） and uric acid （UA） were compared. History of smoking and heredity of cardiovascular diseases were surveyed. Results Level of BMI, TG, LDL and prevalence rate of blood fat abnormality in high normal BP group were significantly higher than those in normal BP group （r=2. 023, 2. 191, 2. 336, P〈0.05; x^2 =7. 535, P〈0.05）, but no significant differences on UA, TC, HDL, smoking habit and familial inherited cardiovascular diseases were found between groups. Conclusions The flying personnel with high normal BP run higher risk of suffering cardiovascular diseases. Medical interventions for controllable risk factors are suggested.
