摘　　要：目的分析云南省18个少数民族2009-2018年乙型病毒性肝炎(hepatitis B virus,HBV)流行趋势,探索云南省乙肝发病率的民族差异。方法基于2009-2018年中国疾病预防控制信息系统中乙肝报告发病数据,采用描述流行病学方法对不同少数民族的乙肝发病情况进行描述分析;采用K-means聚类法方法对不同民族的乙肝年均发病率进行探索分析。结果 2009-2018年云南省年平均发病率为44.26/10万,低于全国总体水平;少数民族乙肝年平均发病率为41.27/10万,低于云南总体水平。不同民族乙肝流行趋势各有异同,佤族的年均发病率明显高于其他(95.26/10万),景颇族最低(22.51/10万)。按乙肝发病率高低将各民族分为3类:高发民族、中发民族和低发民族。结论云南省乙肝发病率存在民族差异,部分民族发病率高于全国,是乙肝防控工作的重点人群。Objective To analyze the epidemic trend of hepatitis B virus(HBV)in 18 minority nationalities in Yunnan Province from 2009 to 2018,so as to explore the ethnic differences in the incidence of HBV in Yunnan Province.Methods Based on the reported incidence data of hepatitis B in China’s disease prevention and control information system from 2009 to 2018,descriptive epidemiology method was used to describe and analyze the incidence of hepatitis B in different ethnic groups,and K-means clustering method was used to explore and analyze the annual average incidence of hepatitis B in different ethnic groups.Results From 2009 to 2018,the average incidence of hepatitis B in Yunnan Province was 44.26/100000,which was much lower than the overall level of China every year;the average incidence of hepatitis B in ethnic groups was 41.27/100000,slightly lower than the overall level of Yunnan every year.The prevalence of hepatitis B was different in different ethnic groups.The average incidence of Wa was significantly higher than others(95.26/100000),and Jingpo was the lowest(22.51/100000).According to the incidence of hepatitis B,different ethnic groups were divided into three categories:high incidence ethnic group,middle incidence ethnic group and low incidence ethnic group.Conclusion There are ethnic differences in the incidence of hepatitis B in Yunnan Province.The incidence of hepatitis B in some ethnic groups is higher than that in the whole country all the year round,which is the key population in the prevention and control of hepatitis B.
