目的为了解我县肺结核病的流行特征及趋势,为预防控制措施的制订提供依据。方法依托结核病网络专报系统为平台,对睢宁地区2005—2008年肺结核流行病学情况进行了统计分析。结果我县肺结核患病率从2005年74.24/10万下降至2007年53.64/10万,但2008年起患病率明显上升至79.06/10万。肺结核菌阳率高于菌阴率(P<0.01),但菌阳率有下降趋势。近年来新发肺结核的病人数及所占比例逐渐减少,但肺结核的复发病例明显增加,从2005年7.82%上升至2008年13.42%,此次上升趋势具有统计学意义(P<0.01)。结论我县肺结核痰涂片阳性患者比率明显高于痰涂片阴性的患者,新发病例数呈下降趋势,但复发病例的比例在逐渐升高。
Objective To understand the epidemiological features and trends of pulmonary tuberculosis in our county and provide the basis for the prevention and control measures. Methods Relying on TB network reporting system as a platform, a statistical analysis was made on the epidemiology of TB in Suining in 2005-2008. Results The prevalence of tuberculosis in our county dropped from 74.24 / 100 000 in 2005 to 53.64 / 100 000 in 2007, but the prevalence rose markedly to 79.06 / 100 000 in 2008. The positive rate of TB was higher than that of negative (P <0.01), but the positive rate of TB was declining. In recent years, the number and proportion of newly diagnosed pulmonary tuberculosis gradually decreased, but the recurrence rate of tuberculosis increased significantly from 7.82% in 2005 to 13.42% in 2008, and the upward trend was statistically significant (P <0.01). Conclusions The proportion of sputum smear-positive patients in our county is significantly higher than that in sputum smear-negative patients. The number of newly diagnosed cases shows a decreasing trend, but the proportion of recurrent cases is gradually increasing.
