1998年内蒙古自治区结核病流行病学抽样调查报告

Report on Inner Mongolia Random Survery For The Epidemiology of Tuberculosis in 1998

目的 :了解全区的结核病疫情动态 ,评价防治措施的效果 ,为制定全区 2 0 0 1～ 2 0 1 0年结核病防治规划提供科学依据。方法 :采取分层、整群、等比例随机抽样 ,全区调查点 30个。对 0～ 1 4岁儿童进行结核菌素试验 ,≥ 1 5岁人群和结核菌素反应≥ 1 0mm的儿童进行胸透 ,对胸透异常和咳嗽、咳痰症状≥ 3周者进行摄片 ,痰涂片和培养检查 ,培养阳性进行抗结核药物敏感试验。对 1 997年死亡情况进行回顾调查。结果 :实检人数为 5 382 6人 ,占应检人数的 97 1 %。活动性肺结核患病率为 6 87 4 / 1 0万 ,涂阳肺结核患病率为 1 6 1 6 / 1 0万 ,菌阳肺结核患病率为 1 83 9/ 1 0万 ,与 1 990年比年递降率分别为 2 5 7% ,7 31 %和 6 85 %。我区结核病疫情仍高于 1 990年全国平均水平。结论 :全区的结核病疫情仍十分严重 ,东西部发展不平衡 ,疫情下降缓慢。

Objective:To realize the varied status of the epidemiological situation of tuberculosis in Inner Mongolia and evalute the efficacy of control measures as well as to provide the scientific basis for the preparation of Inner Mongolia Tuberculosis Control Program(2001～2010).Methods:The multi-stratified grouping random sampling method was used and the proportional sampling was utilized for Inner Mongolia as a whole.A total of 30 investigation points was sampling.Tuberculin testing was carried out among all children of aged 0 to 14 years,chest X-ray fluoroscopy was applied to all population aged 15 or more and the testees of children with positive tuberculin reaction (≥10mm).Chest X-ray radiography,sputum direct smear and cultural examination were applied to all with tuberculosis symptom of cough and expectoration more than three weeks and all examinees with abnormal finding during fluoroscopy.Sensitivety testing of anti-tuberculosis drugs was conducted for all isolated colonies from positive sputum cultural examination.A retrospective study of tuberculosis mortality was investigated.Results:The actual examined population in this survey was 53826 (97.1%).The prevalence of active,smear positive and bacteriological positive pulmonary tuberculosis were 687.4/100000,161.6/100000,and 183.9/100000,respectively.The annal decreasing rates between 1990 and 1998 for active,smear positive and bacteriological positive pulmonary tuberculosis were 2.57%,7.31% and 6.58%,respectively.The epidemiological situation of tuberculosis of Inner Mongolia is much serious than the national averagelevel of 1990.Conclusion:The magnitude of tuberculosis in Inner Mongolia is still serious and it was imbalanced between east and west areas.The epidemiolgical situation in Inner Mongolia was less improved.
