湖州市某院严重急性呼吸道感染者流行病学及危险因素分析

Epidemiological characteristics and risk factors in cases of severe acute respiratory infeetion in a hospital of Huzhou City

[目的]分析湖州市某医院住院严重急性呼吸感染病例流行病学特征和危险因素,为制定预防控制措施提供科学依据。[方法]对2009年12月—2010年12月湖州第一人民医院开展的住院严重急性呼吸道感染病例研究资料进行分析,分析流行病学特征和危险因素。[结果]湖州第一人民医院共报告住院严重急性呼吸道感染病例232例,占所有同期入院病例数的2.46%。发病时间以冬春季为主,发病年龄以0～5岁儿童为主。临床特征以发热、咳嗽、咽痛、呼吸急促为主,84.91%病例并发肺炎。运用二分类logistic回归分析建立重症病例危险因素回归模型,结果发现体质指数(BMI)、是否有心血管疾病病史、气短和呼吸急促为发生住院严重急性呼吸道感染的危险因素,且均有统计学意义。[结论]湖州第一人民医院住院严重急性呼吸道感染主要发生在儿童,冬春季高发,多数发生下呼吸道感染。危险因素为高BMI、心血管疾病病史等。

[Objective] To provide scientific evidence for making strategies and measures for disease prevention and control,we analyzed the epidemiological characteristics and risk factors of hospitalized cases of severe acute respiratory infeetion（SARI） in a hospital of Huzhou City. [Methods] We analyzed the data on SARI cases collected from the First People＇s Hospital of Huzhou between 2009 and 2010. [Results] The First People＇s Hospital of Huzhou reported 232 SARI cases,which accounted for 2.46% of all cases admitted to hospital in the same period.The crest-time was winter and spring,and the peak age was 0~5 years old children.Most of the clinical symptoms in the cases were fever,cough,angina,shortness of breath and so on,and 84.91% SARI cases were accompanied by pneumonia.With the binary logistic regression analysis,we established a regression model about the risk factors on the cases.Finally,body mass index,a history of cardiovascular disease and shortness of breath entered the regression model.They were the risk factors of the SARI cases. [Conclusion] SARI cases occur mainly in children in Huzhou,the crest-time being winter and spring,and most of the cases are accompanied by lower respiratory infection.The risk factors are body mass index,a history of cardiovascular disease,and so on.
