摘要
目的分析赤峰市丙型病毒性肝炎(简称“丙肝”)的流行特征和变化趋势,为制定HCV感染防控措施提供科学依据。方法采用描述流行病学方法分析2013—2021年赤峰市丙肝的流行病学特征,采用χ^(2)检验进行组间比较,不同年份的发病率变化趋势采用趋势χ^(2)检验。结果2013—2021年赤峰市累计报告丙肝病例27189例,年平均发病率65.60/10万,2018年发病率最高为78.73/10万,各年份发病率差异有统计学意义(χ^(2)=574.419,P<0.001)。丙肝年平均发病率居前三位的旗县依次为宁城县(248.67/10万)、巴林左旗(81.22/10万)和敖汉旗(53.80/10万),各区(旗、县)发病率差异有统计学意义(χ^(2)=33961.545,P<0.001)。丙肝发病率男性高于女性,差异有统计学意义(χ^(2)=1341.960,P<0.001),发病年龄主要集中在40~<80岁年龄组,占91.88%,70~<80岁年龄组发病率最高(213.60/10万),不同年龄组发病率差异有统计学意义(χ^(2)=29225.413,P<0.001),职业分布以农民为主,占87.20%。结论赤峰市丙肝疫情呈先升后降趋势,有明显的地区和人群分布,应加强对重点地区和人群的疫情监测并采取有效措施,以有效遏制丙肝的传播风险。
Objective To analyze the epidemiological characteristics and trends of viral hepatitis C(referred to as hepatitis C)in Chifeng City,and to provide a scientific basis for the development of prevention and control measures for HCV infection.Methods A descriptive epidemiological method was used to analyze the epidemiological characteristics of hepatitis C in Chifeng City from 2013 to 2021.Chi-square test was used for group comparisons,and trend Chi-square test was used to analyze the trend in the incidence rates in different years.Results A total of 27189 cases of hepatitis C were reported in Chifeng City from 2013 to 2021,with an average annual incidence rate of 65.60/100000.The highest incidence rate was 78.73/100000 in 2018,with a statistically significant difference in incidence rates between years(χ^(2)=574.419,P<0.001).The top three counties with the highest average annual reported incidence of hepatitis C were Ningcheng County(248.67/100000),Balin Left Banner(81.22/100000),and Aohan Banner(53.80/100000).There were statistically significant differences in reported incidence rates among districts(banners andcounties)(χ^(2)=33961.545,P<0.001).The incidence of hepatitis C was higher in males than in females,and the difference was statistically significant(χ^(2)=1341.960,P<0.001).The age group of incidence was dominated by the age group of 40 to<80 years old,accounting for 91.88%,and the age group of 70 to<80 years old had the highest incidence(213.60/100000).The difference in incidence rates between different age groups was statistically significant(χ^(2)=29225.413,P<0.001).The occupation distribution was predominantly peasants,accounting for 87.20%.Conclusion The reported epidemic situation of hepatitis C in Chifeng City shows a trend of increasing first and then decreasing,with obvious regional and population distribution.It should be necessary to strengthen epidemic surveillance in key areas and populations and take effective measures to effectively curb the risk of hepatitis C transmission.
