Aim of the study was to assess cardiovascular effects in the farmers exposed to noise. We assessed two samples of 143 farmers using tactor (mean age 51.0 +/- 10.5 years, length of service 33.0 +/- 10.5 years) and 193 farmers not exposed to noise (controls) (mean age 48.3 +/- 13.7 years, length of service 30.6 +/- 14.7 years). After the phonometric measurements all farmers were undergone to a medical examination, measurements of blood pressure, a audiometric test and a electrocardiogram. The collected data show an increased prevalence of hypertension and electrocardiographic anomalies in farmers exposed to noise (systolic hypertension n. 53, 37.1%; diastolic hypertension n. 60, 42.0%; electrocardiographic anomalies n. 44; 30.8%) compared to the control group (systolic hypertension n. 23, 16.1%; diastolic hypertension n. 26, 18.2%; electrocardiographic anomalies n. 5; 3.5%) (systolic hypertension p = 0.002; diastolic hypertension p = 0.003; electrocardiographic anomalies p = 0.030). Our results could be taken to mean that there are effects of chronic exposure to noise on cardiovascular apparatus; this would stimulate the screening programmes for farmers.
本研究的目的是评估接触噪音的农民的心血管影响。我们评估了两组样本，一组是143名使用触觉器的农民（平均年龄51.0±10.5岁，工作年限33.0±10.5年），另一组是193名未接触噪音的农民（对照组）（平均年龄48.3±13.7岁，工作年限30.6±14.7年）。在进行声级测量后，所有农民都接受了医学检查、血压测量、听力测试和心电图检查。收集的数据显示，与对照组相比，接触噪音的农民中高血压和心电图异常的患病率增加（收缩期高血压53例，37.1%；舒张期高血压60例，42.0%；心电图异常44例，30.8%）（对照组收缩期高血压23例，16.1%；舒张期高血压26例，18.2%；心电图异常5例，3.5%）（收缩期高血压p = 0.002；舒张期高血压p = 0.003；心电图异常p = 0.030）。我们的结果可能意味着长期接触噪音对心血管系统有影响；这将促使针对农民的筛查项目。
