常州市化工行业工人脂肪肝患病情况调查

目的了解化工产业工人脂肪肝发病情况，探索相关预防措施。方法选择常州市多家化工企业作业工人1880名为观察组，其他行业人员1852人作为对照组，检测工作场所中有害物质浓度，采用B型超声仪对人体肝脏进行检查，同时检查其肝功能、血脂水平。结果观察组工作场所中存有甲苯、二甲苯、氯乙烯、苯胺、正己烷，但检测数据未超标；观察组1880人中检出脂肪肝患者366人，检出率为19．5％；对照组1852人检出脂肪肝274人，检出率为14．8％，2组差异有统计学意义（x^2=14．3，P〈0．01）；2组间不同年龄组脂肪肝检出率差异有统计学意义（x^2=12．56，P〈0．01）。结论化工作业工人脂肪肝发病率高于其他行业，需进一步采取措施改善该职业人群的健康状况。

Investigation of The Prevalence of Fatty Liver among Chemical Industry Workers in Changzhou City

Objective]To understand the prevalence of fatty liver among chemical industry workers, and explore the related preventive measures.Methods] A total of 1880 workers from several chemical enterprises were selected as observation group, 1852 workers from other enterprises as control group. The concentration of harmful substances was measured; B ultrasonic instrument was used to conduct liver examination, and the liver function and blood lipid level were examined simultaneously.Results]Toluene, xylene, vinyl chloride, aniline, n-hexane existed in the workplaces of observation group, however, the detected values did not exceed the standard. 366 cases of fatty liver(19.5%) were detected in observation group of 1880 workers; 274 cases of fatty liver (14.8%) were detected in 1852 workers of control group, the difference between 2 groups was significant(χ2=14.3,P＜0.01);significant difference of detectable rate existed between different age groups of the 2 groups(χ2=12.56,P＜0.01).Conclusion]The incidence of fatty liver among chemical-exposed workers is higher than that among workers in other industries, it is necessary to take further measures to improve the health conditions of this population.
