摘　　要：目的分析江西省2005-2012年急性乙型病毒性肝炎（乙肝）的流行病学特征,为预防控制乙肝提供参考。方法对中国疾病预防控制信息系统的疾病监测信息报告管理系统中,江西省2005-2012年急性乙肝报告病例的流行病学特征进行分析。结果江西省2005-2012年乙肝报告发病率波动在71.79/10万-81.33/10万。报告的乙肝病例中,急性乙肝占5.71%-12.46%,发病率从2005年的8.00/10万降至2012年的4.50/10万。〈15岁儿童急性乙肝年平均发病率低（1.73/10万）,2010-2012年均〈1/10万。不同性别间发病率差异有统计学意义（χ2=6816.90,P〈0.05）。急性乙肝病例农民最多（占52.25%）。萍乡市8年急性乙肝报告发病率〉10/10万,年最高报告发病率达31.72/10万。结论江西省急性乙肝报告发病率呈下降趋势,〈15岁儿童下降更为明显。Objective By analyzing the epidemiological characteristics of acute Hepatitis B cases in Jiangxi province in 2005- 2012,we sought to develop a guideline on prevention and control of Hepatitis B.Methods We conducted epidemiological analysis using data from Jiangxi acute Hepatitis B cases reported during 2005-2012 that were in the China information system for disease control and prevention.Results The reported incidence of Hepatitis B increased between 1990 and 2012 in Jiangxi.The incidence rate of Hepatitis B during 2004 to 2012 varied from 71.79 /100 000 to 81.33 /100 000.Among all the reported cases of hepatitis B during 2005-2012,the percent of cases that were acute hepatitis B case varied from 5.71% to 12.46%,and during this time,the incidence rate dropped from 8.00 /100 000 in 2005 to 4.50 /100 000 in 2012.The incidence among 15-39 years old was the highest,and that of children under 15 years of age was the lowest（ less than 1/100 000 in2011 and2012）.Among children under 9 years old,the incidence among infants was relatively high,and ranked first every year from 2009 to 2012.The incidence by gender was statistically significantly different（ χ2=6816.90,P 〈0.05）.Among all acute hepatitis B cases,farmers had the largest number of cases,accounting for 52.25% of cases.The incidence of acute hepatitis B in Pingxiang municipality was more than 10 /100 000 in the past 7 years,and ranked first every year among 11 municipalities,with a peak of 31.72 /100 000.Conclusion There was a decreasing trend of acute hepatitis B incidence in Jiangxi province,especially among children under15 years of age.It is necessary to strengthen prevention and control of hepatitis B in high incidence areas.The incidence of acute cases is representative of current hepatitis B transmission.
