2013—2015年甘肃省企事业单位脂肪肝流行病学调查研究

Epidemiological investigation of fatty liver in enterprises and institutions in Gansu Province during 2013-2015

目的调查甘肃省人群脂肪肝的分布情况,研究者年龄、性别、接触放射线和胆囊切除与脂肪肝的发生是否有关。方法选取2013年1月—2015年12月甘肃省疾病预防控制中心体检的人群进行B超检查,以年为单位进行脂肪肝发病趋势比较,对性别、各年龄段、是否接触放射线以及胆囊是否切除人群间脂肪肝检出率进行比较。结果 2013、2014、2015年数据分析均显示:性别、年龄、工种(放射人员)、胆囊切除与脂肪肝的发病有关;其中男性脂肪肝的检出率明显高于女性;男性脂肪肝检出率最高的年龄段分布为48~57岁,女性脂肪肝检出率最高的年龄段分布为48岁以上;放射人员脂肪肝的检出率高于非放射人员;胆囊切除人员检出率高于非胆囊切除人员;差异均有统计学意义(均P<0.05)。2013年脂肪肝的总检出率为13.56%,2014年为14.93%,差异有统计学意义(P<0.05);2015年脂肪肝的总检出率为14.27%,和2014年差异无统计学意义(P>0.05)。结论脂肪肝的发生与年龄、性别有关,放射人员和胆囊切除是脂肪肝发病的危险因素,甘肃省企事业单位人员脂肪肝的发病率并未呈现逐年上升的趋势。

Objective To investigating the distribution of fatty liver in Gansu Province and tostudythe relationship between age, sex, type of work(radiation workers), cholecystectomy and the occurrence of fatty liver. Methods Subjects who received type-B ultrasound examination from Gansu Center for Diseases Prevention and Control during January 2013 and October 2015 were selected. Incidence rates of fatty liver between male and female, different age groups, radiation workers and non radiation workers,cholecystectomy and non cholecystectomy groups were compared. Result The data of 2013, 2014,2015 indicated that the incidence of fatty liver was related with age, gender, type of work and cholecystectomy. Chi-square test showed that the incidencerate of fatty liver in men was significantly higher than women(P<0.05); the highest detection rates of age distribution in men was 48-57 year sold, and the highest detection rates of age distribution in women was over 48 years old(P<0.05); the detection rate of fatty liver in radiation workers was significantly higher than that in non-radiation workers(P<0.05); the detection rate of cholecystectomy group was significantly higher than that of non cholecystectomy group(P<0.05). The detection rate in 2014 was significantly different from 2013(P<0.05), but there was not statistical significance between 2014 and 2015. Conclusion Age and gender are profoundly associated with the incidence of fatty liver; radiation work and cholecystectomy are risk factors for the incidence of fatty liver. The incidence of fatty liver in enterprises and institutions in Gansu Province has not been increasing year by year.
