[目的]为了解南方甲肝发病趋势。[方法]应用文献综述、等级相关等方法对1990~2008年发表有关数据进行分析。[结果]1990～2007年中国南方甲肝发病与全国比较相关系数(rs)在0.6848~0.9912,与上世纪90年代相比绝大部分省、市发病降幅在72.81%~99.1%,少数市、区高于全国水平(147.08%~550.93%),福州等大城市有间隔3~7年周期性波动,1996年前有春季和夏秋季峰,此后季节波动消失。小年龄发病下降,大年龄增多,出现明显年龄后移,男性高于女性,职业以农民、学生,散居儿童为主。[结论]甲肝受多种因素影响,江苏、台州人群接种率分别为10.11%和4.68%均获控制发病结果,提示可能存在其他干预因素。
[Objective] To understand the trend of hepatitis A in southern China. [Methods] Using literature review, rank correlation and other methods, the data published from 1990 to 2008 were analyzed. [Results] The correlation coefficient (rs) of incidence of hepatitis A in South China from 1990 to 2007 was 0.6848 ~ 0.9912, which was 72.81% ~ 99.1% less than that of the 1990s in most provinces and cities. Higher than the national average (147.08% ~ 550.93%). Large cities such as Fuzhou fluctuated cyclically between 3 and 7 years ago. There were spring and summer peaks before 1996 and the seasons disappeared thereafter. The incidence of small age decreased, older age increased significantly after the age shift, men than women, occupation to farmers, students, mainly diaspora. [Conclusion] Influenza A is affected by many factors. The vaccination rates in Jiangsu and Taizhou were 10.11% and 4.68%, respectively, which controlled the incidence of the disease, suggesting that other intervention factors may exist.
