2001-2009年2个国家级贫困县空洞性肺结核流行病学分析

目的了解四川贫困地区空洞性肺结核的流行状况,为卫生主管部门制定结核病防控政策提供参考。方法采用定基比、环比发展速度及季节指数对四川南充2个国家级县2001-2009年报告的空洞性肺结核病例进行分析。结果 2001-2009年2个国家级贫困县空洞性肺结核报告率在2006年以前呈上升趋势,2006年报告率达到最高,为7.00/10万;2006年后逐年下降,2009年报告率为最低,为1.49/10万;报告的空洞性肺结核病患者中涂阳患者占87.5%,男性多于女性;患者年龄集中在20～60岁;各月份均有发病,6月份发病达到高峰。结论空洞性肺结核病患者中涂阳比例较高,2001-2009年2个贫困地区空洞性结核病防治已取得一定效果,仍需加强涂阳空洞性肺结核的防控。

Cavitary Pulmonary Tuberculosis in Two State-designated Impoverished Counties,2001-2009

Objective To provide reference for the health authorities to develop tuberculosis prevention and control by understanding the epidemiological status of cavitary pulmonary tuberculosis in Poverty-stricken areas of Sichuan province.Method Speed of development(fixed base relative,link relative) and seasonal index were used to analyze the data of cavitary pulmonary tuberculosis reported in two state-designated impoverished counties of Nanchong district from 2001 to 2009.Results There were increasing new cases reports before 2006 and decreasing reports after 2006.The highest incidence rate was 7.00/105 in 2006 and the lowest incidence rate was 1.49/105 in 2009.The smear-positive patients accounted for 87.5% of the reported cavitary pulmonary tuberculosis patients,and males were more than females.Most cases were of the ages from 20 to 60 years.The incidence occurred all around year,and peaked in June.Conclusion The smear-positive rate of the reported cavitary pulmonary tuberculosis patients was high.Although achivement had been made in the tu berculosis control programs in the impoverished counties,the control of smear-possitive cavitary pulmonary tuberculosis still need to be strengthened.
