摘要
目的了解舟山市某医院5岁以下严重急性呼吸道感染（SARI）住院患儿的流行特点及住院时间影响因素。方法采集2013年2月至2014年2月期间在舟山某医院儿内科病房住院治疗的352例5岁以下SARI病例的鼻咽部分泌物进行实验室检测，同时收集患儿的既往病史及临床特征等相关信息。采用多因素Logistic回归分析影响患儿住院时间的因素。结果患儿临床主要表现为发热100．00％（352／352）、咳嗽67．05％（236／352）、咽红44．03％（155／352）和气促22．73％（80／352）；流感病毒阳性检出率为8．20％（29例），且以甲型为主；纳入研究的SARI患儿中位住院天数为7（5，8）d。多因素Logistic回归分析表明SARI患儿住院时间〉7d与咳嗽（OR=2．443，95％CI：1．323-4．513）、胸片异常（OR=1．395，95％CI：1．125-1．730）和有并发症（OR=3．806．95％CI：1．249～11．595）相关。结论舟山地区5岁以下SARI住院患儿流感病毒检出率较高，且以甲型为主，患者的住院时间长与咳嗽症状、胸片异常和有并发症有关。
Objective To study the epidemiological characteristics of severe acute respiratory infeetion（SARI） in children under 5 years old and factors influencing length of stay in hospital in Zhoushan City. Methods We recruited 352 SARI children below 5 years old and hospitalized in pediatric wards from Feb. 2013 to Feb. 2014. Cases＇ nasopharyngeal aspirate specimens were sampled for laboratory testing. Meanwhile, medical history and clinical characteristics were also collected by questionnaire. The factors influencing length of stay were analyzed by multivariatelogisticregression. Results The main clinical manifestations of SARI children were fever （100.00%, 352/ 352）, cough （67.05%, 236/352）, pharyngalgia （44.03%, 155/352） and anhelation （22.73%, 80/352）. The positive rate of influenza virus was 8.20%（29 cases）, mainly in influenza A virus. The average length of stay was 7 （5, 8） days. Multivariate unconditional logistic regression analysis demonstrated that cough （OR =2.443,95% CI：1.323 4.513）, abnormality of lung （OR=1.395,95%CI：1.125-1.730） and complications （0R=3.806, 95%CI：1.249-11.59） were associated with over 7-day hospital stays. Conclusions The positive detection rate of influenza virus in SARI children under the age of five is high in Zhoushan area, mainly in influenza A virus. Cough, abnormality of lung and complications are risk factors of the hospital stays.
