【摘要】 目的探讨噪声与作业工人慢性胃病的相关性。方法对广州6家制造业工厂693名作业工人的职业健康危害进行现况调查,将发现的38例慢性胃病现患者设为病例组,所有对象经性别、年龄排序后,按性别一致、年龄±1岁分组,在每个病例对应的组中,统一依次按隔位选1原则选取4名无现患者(1∶4配对),共152名工人为对照组,开展病例对照研究。相关性分析与评价采用卡方检验和条件Logistic回归分析。结果 (1)慢性胃病现患率男女基本一致,但随年龄的增加而增加(卡方趋势性检验P值=0.001);(2)病例组噪声接触率显著高于对照组,以接噪工龄≤5年者较为突出;(3)调整文化程度、吸烟、饮酒和其他职业接触等混杂因素后,噪声接触与患慢性胃病的危险性增加显著相关,接噪≤5年患慢性胃病的危险较明显。结论噪声接触可增加患慢性胃病危险。更多还原

【Abstract】 Objective To study the association of industrial noise exposure with chronic gastric disorders in workers in Guangzhou city.Methods Firstly,a cross sectional survey was performed,693 workers from 6 manufacturers in Guangzhou were examined,among them 38 cases of chronic gastric disorders were found as case group.All the objects were sorted according to gender and age,1∶4 match principle was used in the study that was 4 controls/1 case in each sub-group,therefore,152 controls were selected.Additionally,Chi-square test and multivariable conditional logistic regression model were used for the analysis and assessment of the association.Results(1) There was a similar prevalence of chronic gastric disorders in men and women,the prevalences increased with age(Pfor trend=0.001).(2)The noise exposure prevalence was significantly higher in case group,the major proportion of exposure duration were≤5 years.(3)After adjusting the confounding factors such as education,smoking,drinking and other occupational exposure etc.the risk of chronic gastric disorders was obviously correlated to noise exposure,especially the exposure less than 5 years.Conclusion The results suggested that noise exposure may increase the risk of suffering from chronic gastric disorders.更多还原
