为了解 2 0 0 1年冬季北京市城区居民流行性感冒 (流感 )样病例发病及流感疫苗接种情况 ,使用北京市 8个城区的电话局向号和随机数字相结合产生的电话号码 ,对城区居民进行电话调查 ,同时对部分 3～ 6岁幼儿和≥ 6 0岁老人开展自我管理式问卷调查。结果显示 :2 0 0 1年冬季北京市城区居民流感样疾病罹患率为 10 8% ,≤ 6岁、7～18岁、19～ 5 9岁、≥ 6 0岁人群流感样疾病罹患率分别为 4 0 0 %、16 7%、9 2 %、6 7% ,各年龄组人群罹患率差异有显著的统计学意义。≥ 6 0岁患慢性病老人罹患率为 8 3% ,非慢性病老人罹患率为 4 3% ,差异有显著的统计学意义。城区居民流感疫苗接种率为 10 5 % ,≤ 6岁、7～ 18岁、19～ 5 9岁、≥ 6 0岁人群流感疫苗接种率分别为36 8%、2 8 8%、6 7%、7 9%。接种组和未接种组幼儿流感样病例罹患率和≥ 6 0岁老人的人周发病率差异均无显著的统计学意义。表明 2 0 0 1年冬季北京市城区居民存在流感样病例流行 ,幼儿和患慢性病老人是预防流感样病例的重点人群 ,流感疫苗幼儿接种率较高 ,≥ 6 0岁老人接种率低 ,应积极在老年人群中推广流感疫苗的使用 In order to understand the incidence of influenza-like illness and flu vaccination in urban areas of Beijing in winter in 2001, the telephone numbers generated by combining the telephone numbers of the eight city districts in Beijing with random numbers were used to evaluate the prevalence of influenza in urban areas Residents conducted telephone surveys and self-administered questionnaires were conducted on some children aged 3 to 6 and over 60 years of age. The results showed that the prevalence of influenza-like illness among urban residents in Beijing in 2001 was 108%, ≤6 years, 7-18 years, 19-59 years and ≥60 years. The prevalence of influenza-like illness was 4 0 0%, 16 7%, 9 2%, 6 7%. There was a significant difference in the attack rate among all age groups. ≥6 years old suffering from chronic diseases, the elderly attack rate was 83%, non-chronic disease elderly attack rate was 43%, the difference was statistically significant. The flu vaccination rate among urban residents was 105%, ≤6 years old, 7-18 years old, 19-59 years old, and the flu vaccination rate was 36.8%, 28.8%, 67% respectively. 7 9%. There were no statistically significant differences in the incidence of influenza-like illness among infants in vaccinated and non-vaccinated groups and in the incidence of human peripheral disease in ≥60-year-olds. The results showed that influenza-like cases were endemic in urban areas of Beijing in winter 2001, and infants and the elderly with chronic diseases were the key populations in prevention of influenza-like illness. The vaccination rate of flu vaccination children was higher, and the vaccination rate of ≥60 years old should be low Promote the use of influenza vaccines in older people
