上呼吸道疾病往往与缺血性心脏病和卒中发病危险增高有关。然而关于在流感流行季节,接种流感疫苗对老年人心脏病住院危险、卒中发病率、院内肺炎及流感发病率,以及总病死率的影响,既往尚无相关研究。本文就此进行了分析。对象与方法为1998～1999和1999～2000年两个流感流行季节中的140055例和146328例受试老人。年龄均>65岁,其中分别有55.6％与59.7％的老人接种了流感疫苗。接种疫苗老人中体质明显较差、并存多种疾病者较多、门诊病人居多,有肺炎住院者亦多;而在未接种疫苗老人中有痴呆和卒中史者多
Upper respiratory diseases are often associated with an increased risk of ischemic heart disease and stroke. However, no studies have been conducted on the impact of vaccination against influenza on hospitalized heart disease risk, stroke incidence, nosocomial pneumonia and influenza incidence, and overall mortality in the flu season. This article has carried on the analysis to this. Subjects and methods were 14,055 and 146,328 elderly people in two flu epidemic seasons from 1998 to 1999 and from 1999 to 2000. All were> 65 years old. Among them, 55.6% and 59.7% of the elderly were vaccinated against influenza. Elderly vaccinated significantly worse constitution, coexisting a variety of diseases are more outpatient patients are mostly hospitalized with pneumonia; and in unvaccinated elderly people with dementia and history of stroke were more
