目的描述天津市西青区2004—2015年丙型病毒性肝炎(简称丙肝)流行特征,探讨天津市西青区丙肝流行趋势,为制定本辖区丙肝防控策略提供科学依据。方法采用描述性流行病学方法,分析传染病信息报告管理系统中2004—2015年天津市西青区丙肝病例。结果天津市西青区丙肝报告发病率在1.63/10万~5.77/10万之间,年平均发病率为3.89/10万,2012—2015年发病上升速度快;丙肝发病数占病毒性肝炎发病数的比例上升10.07倍(χ2=131.39,P=0.000,χ2趋势=114.29,P=0.000);每年丙肝各月份均有发病,无明显季节性特征;年均发病率城乡结合地区(3.91/10万)高于农村地区(2.17/10万),Z=3.81,P=0.000;男女性别比为1.17,45~69岁年龄组发病数占全部发病数的53.39%;职业分布以农民、离退休人员和家务及待业人员为主,占55.50%。结论近年来,天津市西青区丙肝发病率呈快速上升趋势,应提高丙肝监测水平,对重点地区及高危人群采取综合防控措施。
