目的 探讨北京市6岁以下儿童手足口病流行特征,为有效干预提供科学依据.方法 采用现况研究的方法,对北京市2008-2013年6岁以下儿童手足口病发病情况进行动态分析,采用Excel 2007建立数据库,应用SPSS 16.0进行统计学分析,各组之间率和构成比的比较采用卡方检验.结果 2008-2013年北京市6岁以下儿童手足口发病人数为135 825,占总发病人数的90.62％,平均年发病专率为2718.41/105;不同年份男性手足口病发病均高于女性,呈现周期性;6岁以下儿童手足口病发展速度呈现出先增快后减缓的趋势,女性发展速度高于男性;各年龄组男性手足口病发病均高于女性,但不同性别组的年龄发病分布趋势一致,3-4岁年龄组发病最高.结论 北京市6岁以下儿童手足口发病专率较高、发展速度较快,应该高度关注并开展相关影响因素研究.“,”Objective To discribe the epidemiological trends and patterns of hand-foot-mouth disease among children under 6 years old in Beijing,so as to provide scientific evidences for effective intervention measures.Methods The prevalence of hand-foot-mouth disease among children under 6 years old in Beijing from 2008 to 2013 were dynamically analyzed with a cross section method.The database was set up with Excel 2007.SPSS 16.0 was used for the statistical analysis.The rates and proportion ratios in different groups were compared with chi-square tests.Results From 2008 to 2013,the number of hand-foot-mouth disease cases among children under 6 years old in Beijing was 135 825,accounting for 90.62％ of all handfoot-mouth disease patients.The average level of annual specific morbidity rate was 2718.41/105.The male patients were always more than females in each year,with a periodicity.The progression of the disease showed a trend of initial acceleration then slowing down,while faster progression in females than males.The numbers of male patients were always higher than females in every age group,but the distribution of disease onset showed similar trends in different gender or age groups,with the highest prevalence in 3-4 years old group.Conclusions The specific morbidity rate and progression of hand-foot-mouth disease among children under 6 years old in Beijing was relatively high.The situation should be concerned and the influencing factors should be studied.
