目的了解汉中市2012-2017年肺结核抗酸杆菌痰涂片结果及变化情况,分析涂阳肺结核患者特征。方法从中国结核病管理信息系统、结核病实验室登记本中收集整理痰涂片镜检数据,并对6年来肺结核患者痰涂片镜检结果进行数据分析。结果 6年来痰涂片阳性率从6. 48%下降到4. 42%,各年发病率差异有统计学意义(P<0. 05),各县区痰涂片阳性率差异有统计学意义(P<0. 05),各年龄组间涂阳结核病患者阳性差异有统计学意义(P<0. 01),涂阳肺结核患者男女构成比差异有统计学意义(P<0. 01);45~54岁年龄组患者数最多,占涂阳肺结核患者的19. 60%,其次为55~64岁年龄组,占17. 04%;男性肺结核患者数多于女性,男、女患者比平均为2. 82:1。结论汉中市2012-2017年结核病疫情呈下降趋势,男性与中老年肺结核患者是防控的重点人群。
Objective To explore the results and changes of tuberculosis acid-fast bacilli sputum smear microscopy in Hanzhong City from 2012 to 2017,and to analyze the characteristics of smear-positive tuberculosis(TB) patients. Methods Data of sputum smear microscopy were collected from Chinese TB Management Information System and TB laboratory registration books. And sputum smear microscopy results in 2012-2017 were analyzed. Results During the 6-year period from 2012 to 2017,the smear-positive detection rates were declined from 6.48% to 4.42%. There were statistically significant differences in the incidence rates in different years(P< 0.05),in the sputum smear-positive rates in different counties/districts(P < 0. 05),in the detection rates of smear-positive TB patients among different age groups(P < 0. 01) and in the male-to-female ratio among smear-positive TB patients(P< 0.01). The age group of 45-54 years had the maximum number of smear-positive TB patients,accounting for 19.60%,followed by the age group of 55-64 years,accounting for 17.04%. Male TB patients were more than female ones,with the male-to-female patient ratio of 2.82: 1. Conclusions The TB epidemics in Hanzhong City in 2012-2017 presented a downward trend.Males,the middle-aged and the elderly were the key populations for TB prevention and control.
