2005-2015年云南省乙型病毒性肝炎流行特征分析

Epidemiology of hepatitis B in Yunnan province, 2005-2015

  • 摘要: 目的 分析2005-2015年云南省乙型病毒性肝炎(乙肝)的流行特征,为乙肝防控策略和措施的制定提供科学依据。方法 采用描述性流行病学方法,对2005-2015年云南省乙肝流行特征进行分析,对不同地区的乙肝年均发病率进行聚类分析。结果 云南省2005-2015年累计报告261 496例乙肝病例,年均发病率为51.99/10万,男女性别比为1.64∶1,乙肝发病集中于15~59岁,占总病例数的82.66%,职业构成以农民为主(61.52%)。累计报告病例居前三位地区为昆明市(51 913例)、昭通市(32 738例)和曲靖市(24 046例)。按年均发病率高低分为高、中、低三类地区,高发地区为昆明市、临沧市和西双版纳州,中发地区为保山市、昭通市、丽江市、文山州、怒江州和迪庆州,低发地区为曲靖市、玉溪市、普洱市、楚雄州、红河州、大理州和德宏州。结论 云南省2005-2015年乙肝发病率男性高于女性,职业以农民高发,年龄以青壮年为主,应加强重点地区、重点人群的防控策略。

     

    Abstract: Objective To understand the epidemiological characteristics of hepatitis B in Yunnan province from 2005-2015 and provide evidence for the prevention and control of hepatitis B. Methods The descriptive epidemiological analysis was conducted by using the incidence data of hepatitis B in Yunnan province from 2005-2015, and K-means clustering analysis was performed for the annual average incidence in different areas. Results A total of 261 496 cases of hepatitis B were reported in Yunnan during this period, the average annual incidence was 51.99/100 000. The ratio of male to female was 1.64:1. Most cases were aged 15-59 years (82.66%) and most cases were famers (61.52%).The cases were reported in 16 prefectures (municipality), and the first three prefectures (municipality) reporting high case numbers were Kunming (51 913 cases), Zhaotong (32 738 cases)and Qujing (24 046 cases). The prefectures (municipality) reporting high incidences were Kunming, Lincang and Xishuangbanna, the prefectures reporting moderate incidences were Baoshan, Zhaotong, Lijiang, Wenshan, Nujiang and Diqing, and the prefectures reporting low incidences were Qujing, Yuxi, Puer, Chuxiong, Honghe, Dali and Dehong. Conclusion The incidence of hepatitis B was higher in males than in females in Yunnan from 2005 to 2015. Most cases were young adults and farmers. It is necessary to strengthen the hepatitis B prevention and control in key areas and in populations at high risk.
