Objective　To analyze the age and gender distribution characteristics of patients positive in sputum mycobacterium tuberculosis culture in regional tuberculosis (TB) laboratory tests of first diagnosis, and to understand the prevalence of TB at Songjiang District, Shanghai recently. Methods　The TB culture results of newly diagnosed patients recorded in the regional TB laboratory at Songjiang District, Shanghai from 2018 to 2021 were collected. The age and gender information of the patients positive in sputum culture were consulted and analyzed for frequency distribution. Results　A total of 767 newly diagnosed TB patients positive in sputum culture were collected from 2018 to 2021. The overall composition ratio of male to female was 2.58∶1. The trend of composition ratio was not obvious during the 4 years. Both male and female patients with positive culture showed the highest peak when they were 20-29 years old; there was no statistical difference between the 4 years.

摘要：

目的　分析区域性结核病实验室检测的初诊患者中痰结核分枝杆菌培养阳性的年龄、性别分布特征，了解近期上海市松江区结核病的流行情况。方法　收集上海市松江区区域性结核病实验室2018年5月至2021年8月记录在册的初诊患者结核分枝杆菌培养结果，查阅记录阳性患者的年龄及性别信息，进行频数分布分析。结果　共收集2018—2021年767例痰结核分枝杆菌培养阳性初诊患者信息，其中男女性别总体构成比为2.58∶1。4年间构成比变化趋势不明显。阳性患者不论男女均在20～29岁呈现出最高峰，各年度间差异无统计学意义。总体数据显示20～<35岁痰结核分枝杆菌培养阳性患者占比53.3%。结论　上海市松江区肺结核发病年龄高峰在20～<30岁，男性明显多于女性。
