The aim of the study was to assess the long-term effects of radiofrequency electromagnetic radiation (EMR) on the cardiovascular system. Two groups of exposed operators (49 broadcasting (BC) station and 61 TV station operators) and a control group of 110 radiorelay station operators, matched by sex and age, with similar job characteristics except for the radiofrequency EMR were studied. The EMR exposure was assessed and the time-weighted average (TWA) was calculated. The cardiovascular risk factors arterial pressure, lipid profile, body mass index, waist/hip ratio, smoking, and family history of cardiovascular disease were followed. The systolic and diastolic blood pressure (SBP and DBP), total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) were significantly higher in the two exposed groups. It was found that the radiofrequency EMR exposure was associated with greater chance of becoming hypertensive and dyslipidemic. The stepwise multiple regression equations showed that the SBP and TWA predicted the high TC and high LDL-C, while the TC, age and abdominal obesity were predictors for high SBP and DBP. In conclusion, our data show that the radiofrequency EMR contributes to adverse effects on the cardiovascular system.
本研究的目的是评估射频电磁辐射（EMR）对心血管系统的长期影响。研究了两组暴露操作人员（49名广播（BC）电台和61名电视台操作人员）以及一组由110名无线电中继站操作人员组成的对照组，对照组在性别和年龄上进行了匹配，除射频EMR外，工作特征相似。评估了EMR暴露情况并计算了时间加权平均值（TWA）。跟踪了心血管危险因素，包括动脉血压、血脂谱、体重指数、腰臀比、吸烟情况以及心血管疾病家族史。两个暴露组的收缩压和舒张压（SBP和DBP）、总胆固醇（TC）和低密度脂蛋白胆固醇（LDL-C）显著更高。研究发现，射频EMR暴露与患高血压和血脂异常的几率增加有关。逐步多元回归方程显示，SBP和TWA可预测高TC和高LDL-C，而TC、年龄和腹部肥胖是高SBP和DBP的预测因素。总之，我们的数据表明，射频EMR会对心血管系统产生不良影响。
