Objective To analyze the epidemic characteristics of pulmonary tuberculosis(PTB) in the elderly people in Suzhou from 2009 to 2018, and we provide a theoretical basis for the establishment of an effective TB control model in the elderly people.
Methods The current address of TB cases with age ≥65 years old in Suzhou was collected for the registration management of TB information management system from 2009 to 2018. The data were analyzed with the descriptive statistical analysis method.
Results From 2009 to 2018, the registered incidence of elderly PTB and the proportion of smear-positive in Suzhou both showed a decreasing trend ( P<0.05), with the annual decline rates were 4.85% and 1.59%, respectively. The registered incidence of PTB in the elderly is 2 times that of the whole population. Elderly PTB registered incidence was the highest in Changshu, of 84.16/100 000.The lowest rate in Gusu district was 14.83/100 000.The incidence of PTB in the elderly with different genders was different ( P<0.05) .The incidence rate was 82.57/100 000 for males, about 3.3 times that of females, which was 24.91/100 000.
Conclusion The registered incidence of elderly PTB in Suzhou presents a declining trend from 2009 to 2018, but still at a high level. The proportion of smear-positive is high. Therefore, the prevention and control work of elderly PTB should be focused on the male population, migrating population and aging areas.
摘要：目的分析2009—2018年苏州市老年人群肺结核疫情特征，为建立有效的老年结核病防治模式提供理论依 据。 方法收集2009—2018年结核病信息管理系统登记管理的现住址为苏州市、年龄>65岁的肺结核病例。采用描述 性流行病学方法分析老年肺结核登记发病的流行特征。 结果2009—2018年苏州市老年肺结核登记发病率和涂阳占 比均呈下降趋势(P<0.05),年递降率分别为4.85%和1.59%。老年人肺结核登记发病率是全人群的2倍。常熟市老年肺 结核登记发病率最高，为84.16/10万，姑苏区最低为14.83/10万。老年人肺结核不同性别登记发病率差异有统计学意义 (P<0.05)，男性登记发病率为82.57/10万，女性为24.91/10万，男性登记发病率约为女性的3.3倍。结论苏州市2009— 2018年老年肺结核登记发病率整体呈下降趋势，但仍处较高水平，且涂阳占比居高，应针对男性人群、流动人口和老龄 化程度较高地区，重点加强老年肺结核防控工作。
