AbstractOBJECTIVE: To examine electrocardiogram (ECG) change of workers after leaving occupational noise exposure. METHODS: In the first phase of the Guangzhou Biobank Cohort Study, 10413 Guangzhou residents aged 50 years or more received a face-to face interview including noise exposure history, a full medical check-up and laboratory tests in 2003 - 4. ECG examination was carried out using 12-lead MAC-CS ECG machine made in HP Ltd, Shanghai, China. ECG of every subject was independently diagnosed by two doctors who had obtained ECG diagnosis qualification. RESULTS: (1) Among 10413 subjects, 70% were female, and more than half were aged 60-69 years. The mean age and education level in males were higher than those in females. (2) 2119 subjects (21.0%) were previously exposed to noise and were retired now. (3) The prevalence of ECG abnormality was respectively 82.4% and 79.1% in females and males. Rate of ECG abnormality increased with age in both females and males (P = 0.000), and was lower in females with higher education level (P = 0.000). There was not significant difference in ECG abnormality between workers previously exposed or unexposed to noise in both females and males (P > 0.05). 4 Comparing workers previously exposed to those unexposed to noise in both females and males, after adjusting for age, educational level and smoking status, the rates of arrhythmia, axes deviation, atria and ventricle hypertrophy, ST-T change and coronary artery syndrome were not significantly different (P > 0.05). CONCLUSION: Our study showed that the prevalence of ECG abnormality was not significantly increased in workers previously exposed to noise and had left exposure now compared to those never exposed to noise. Because our study was cross section and occupational history was obtained from a questionnaire but was not confirmed by the companies, further study is needed. 目的 探討工人脫離職業性噪聲接觸后的心電圖變化.方法 在進行《廣州生物庫隊列研究》時,第一階段收集10 413名年齡在≥50歲居民的一般資料、體格檢查和實驗室檢查結果.受檢者70%為女性,50%以上年齡在60~69歲;受檢者中有2120名(21.0%)曾經接觸職業性噪聲,但均已脫離接觸且為退休或離崗者;用上海惠普有限公司制造的MAC-CS多導聯心電圖機進行12導聯的心電圖檢查;噪聲職業接觸史通過問卷采集,心電圖由2名中級以上具有診斷資格的醫師進行獨立診斷.結果 (1)心電圖異常檢出率女性為82.4%,明顯高于男性的79.1%;不論男性或女性,心電圖異常檢出率隨年齡增加而上升(P=0.000),女性隨文化程度增高而明顯下降(P=0.000),但無論男女,脫離職業性噪聲接觸后,其心電圖異常檢出率與從未職業性噪聲接觸者比較,差異無統計學意義(P>0.05);(2)比較曾經有職業性噪聲接觸與非接觸者心電圖異常的分類,在校正年齡因素和文化程度后,心律失常、心電軸偏移、房或室肥厚、ST-T改變、心肌勞損、冠狀動脈綜合征等比較,差異無統計學意義(P>0.05).結論 脫離職業性噪聲接觸后的工人心電圖異常檢出率未見明顯高于非職業性噪音接觸者.
