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 investigate the distribution of fatty liver in Gansu Province, and to investigate whether age, sex, exposure to radiation and cholecystectomy are related to the occurrence of fatty liver. Methods From January 2013 to December 2015, the Gansu CDC patients were examined by B-mode ultrasonography. The incidence of fatty liver was compared with that of year. The sex, age, exposure to radiation and excision of gallbladder Fatty liver detection rate among the population were compared. Results The data analysis of 2013, 2014 and 2015 showed that gender, age, type of work (radiologist) and cholecystectomy were related to the incidence of fatty liver. The detection rate of male fatty liver was significantly higher than that of female. The detection rate of male fatty liver The highest age distribution of 48 to 57 years of age, the highest detection rate of fatty liver in women age distribution of 48 years of age; radiation detection rate of fatty liver was higher than non-radiation workers; the detection rate of cholecystectum was higher than non- Gallbladder removal; differences were statistically significant (P <0.05). The overall detection rate of fatty liver was 13.56% in 2013 and 14.93% in 2014, with a significant difference (P <0.05). In 2015, the overall detection rate of fatty liver was 14.27%, and the difference was not statistically significant in 2014 Significance (P> 0.05). Conclusions The incidence of fatty liver is related to age and sex. Radiation personnel and cholecystectomy are the risk factors of fatty liver. The incidence of fatty liver in enterprises and institutions in Gansu Province does not show an increasing trend year by year.
