摘要
目的了解南京市0~5岁儿童手足口病(hand,foot and mouth disease,HFMD)的流行病学分布,并探讨气温与儿童手足口病发病的关系,为制定手足口病有针对性的防控措施提供参考依据。方法收集南京市2011—2016年5岁及以下儿童HFMD的日发病数和日气象变量资料。对HFMD流行病学特征进行描述性分析,利用分布滞后非线性模型(distributed lag non-linear model,DLNM)分析HFMD日发病数与日平均气温的关系。结果2011—2016年南京市共报告0~5岁儿童手足口病104977例,男女性别比为1.49∶1,手足口病年均报告发病率为213.5/10万,呈季节性双峰分布,南京市溧水区和浦口区为HFMD高发地区;EV-A71阳性、CV-A16阳性和其他肠道病毒感染阳性分别占HFMD阳性标本的32.5%,29.1%和38.4%;5岁及以下儿童HFMD发病数与日平均气温呈非线性关系,存在明显的滞后效应。当滞后14 d时,气温对手足口病的累积效应呈倒"U"型,气温为25.7℃时效应值最大,累积相对危险度为2.71(95%CI=1.93~3.81);不同人群分析显示,男童和<1岁组儿童更易受气温的影响。结论南京市≤5岁儿童HFMD流行具有季节性、地区性分布特征,气温对HFMD发病存在显著影响。
Objective This study aims to investigate the epidemiological distribution of HFMD and quantify the association of temperature with the incidence of children’s HFMD in Nanjing,China.Methods Daily counts of HFMD in children under 5 years and daily meteorological variables during 2011-2016 were obtained.Descriptive statistics were used to describe the epidemiological characteristics and distributed lag non-linear model(DLNM)was used to assess the associations of temperature on HFMD cases.Results A total of 104977 HFMD cases aged 0-5 years were reported in Nanjing during the study period and the male-to-female sex ratio was 1.49∶1.The average annual incidence was 213.5 per 100000.A bimodal seasonal pattern was observed and the south and west were found to be the high-incidence areas in the city.Of these laboratory-confirmed enteroviruses positive cases,32.5%cases were positive for EV-A71 infections,29.1%cases were positive for CV-A16 infections and 38.4%cases were positive of other enteroviruses infections.The temperature-HFMD relationships were non-linear and showed obvious lag effects.The cumulative relative risk presented as an approximately inverted U-shape over 14 days and peaked at 25.7℃with value of 2.71(95%CI=1.93-3.81).Subgroup analyses revealed that males and children aged<1 year were more vulnerable to temperature variations.Conclusion Epidemiological characteristics of HFMD among children aged 0-5 years old in Nanjing presented temporal and regional distribution.The temperature has significant impact on children’s HFMD occurrence.
