[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 analyze the epidemiological characteristics and risk factors of hospitalized severe acute respiratory infection in a hospital in Huzhou City, and provide a scientific basis for making prevention and control measures. [Methods] From December 2009 to December 2010, Huzhou First People’s Hospital conducted a case-control study of hospital-acquired severe acute respiratory infections and analyzed the epidemiological characteristics and risk factors. [Results] A total of 232 cases of severe acute respiratory infection were reported in Huzhou First People’s Hospital, accounting for 2.46% of all cases admitted in the same period. The onset time in winter and spring-based, age of onset to 0 to 5-year-old children. Clinical features of fever, cough, sore throat, shortness of breath, 84.91% of cases complicated by pneumonia. Binary logistic regression analysis was used to establish the regression model of risk factors for severe cases. The results showed that body mass index (BMI), history of cardiovascular disease, shortness of breath and shortness of breath were the risk factors for hospitalized severe acute respiratory infection, both of which were statistically significant. [Conclusion] Huzhou First People’s Hospital hospitalized with severe acute respiratory infection occurs mainly in children, high in winter and spring, most cases of lower respiratory tract infection. Risk factors for high BMI, history of cardiovascular disease.
