Abstract:
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 44.26/100 000, which was much lower than the overall level of China every year; the average incidence of hepatitis B in ethnic groups was 41.27/100 000, 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 (95.26/100 000), and Jingpo was the lowest (22.51/100 000). 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.
