2009—2019年上海市长宁区病毒性肝炎流行病学特征及发病趋势分析

Joinpoint regression analysis and Epidemiological characteristics of hepatitis in Changning District of Shanghai in 2009-2019

目的研究分析上海市长宁区2009—2019年病毒性肝炎流行病学特征及发病趋势,为病毒性肝炎的防控提供科学指导。方法收集2009—2019年长宁区病毒性肝炎数据,采用描述型流行病学方法对上海市长宁区病毒性肝炎的流行病学特征进行分析;采用Joinpoint软件计算病毒性肝炎发病率的年度变化百分比和平均年度变化百分比,并进行趋势检验。结果2009—2019年长宁区共报告病毒性肝炎3397例,年均发病率49.32/10万。Joinpoint趋势检验结果表明,从型别上看,上升趋势主要是甲肝、乙肝的发病率升高所致。结论长宁区病毒性肝炎年均发病率远低于全国平均水平,但2009—2019年病毒性肝炎发病率总体呈现上升趋势,上海市长宁区病毒性肝炎防控形势依然严峻,乙肝仍是今后病毒性肝炎的防治重点。

Objective To investigate the tendency of viral hepatitis in Changning District,Shanghai,and to provide scientific evidence for decision-making of prevention and control.Methods Cases of viral hepatitis in Changning District from 2009-2019 were collected,and the epidemiological characteristics of viral hepatitis were analyzed by descriptive epidemiological method.Joinpoint regression analysis were used to estimate the annual percent change and average annual percent change,and to perform the trend test.Results Among the 2009-2019 in Changning District,a total of 3397 cases of viral hepatitis were reported,the annual average incidence rate was 49.32/100000.Results from Joinpoint trend analysis indicated that the incidence of viral hepatitis in Changning District was mainly due to hepatitis A and hepatitis B.Conclusions Although the annual incidence rate of viral hepatitis in Changning District is far below the incidence rate of viral hepatitis in China,but it still shows an increasing trend.This shows that the situation of prevention and control of viral hepatitis in Changning is still serious,and hepatitis B remains the key point of prevention of viral hepatitis in Shanghai.
