摘要
[目的]调查分析2005年天津市乙型病毒性肝炎年报告发病率。[方法]根据2005年国家疾病监测信息系统报告(简称网报)乙肝病例数,每月初按上月地区发病不等比例分层随机抽样调查,样本量公式n=4PQ/d2,规定容许误差为0.1P,文献报道慢性乙肝构成比为P=18.92%[2],理论样本量为1715例,实际抽样2702例,调查病例统一填写"天津市病毒性肝炎流行病学调查表",Excel软件输机处理并运用SPSS11.5统计软件对网报前5年和2005年疫情数据进行发病趋势一致性检验。[结果]2005年乙肝急性病例构成为36.50%,校正发病率为18.50/10万;慢性乙肝构成为60.40%,校正发病率为30.66/10万。急、慢性乙肝发病均以成人为主;发病一致性检验表明2005年网络报告发病上高原因主要为网络报告敏感性增加所致。[结论]该市应加强医疗机构乙肝的急、慢性临床分型报告;其次由于网络敏感性上升和报告意识的提高导致乙肝报告发病率继续上升。
[Objective] To analyze the annual reported morbidity of viral hepatitis type B in Tianjin in 2005. [Methods] Basedon the HB eases data of China information system for disease control and prevention, stratified random sampling was carfled out by districts. Sample size formula is n = 4PQ/d2, tolerance error is 0.1P, the reported constituent ratio of chronic HB is P=18.92%. The theoretical sample size was 1 715 eases, but 2 702 cases were sample in practice, the HB patients selected were all required to complete ＂Tianjin individual epidemic questionnaire of viral hepatitis＂. The obtained data was imported by Excel, and according to the surveillance data of 2005 and the previous five years, HB morbidity trend test of concordance was carried on by SPSSll.5 software. [Results] The majority of HB cases were adults. 36.505% eases were acute HB, and the revised incidence rate was 18.50/100 000; 60.40% cases were chronic HB, and the revised morbidity was 30.66/100 000. Morbidity trend test of concordance showed that the rising of sensitivity of net-reporting system was the main factor for higher Morbidity of HB in 2005. [Conclusions] Reporting of clinical classification of HB should be enhanced in medical institution. Otherwise, the rising of sensitivity of net-reporting system and the improvement of reporting awareness are the main reasons for high HB morbidity and would result in its persistent increasing
