目的分析苏南地区流动人口肺结核流行特征及变化趋势,探讨流动人口对当地肺结核疫情的影响,为制定流动人口肺结核防控措施提供科学依据。方法收集苏南3地市2007-2010年的流动人口和本地人口肺结核的监测报表和病案等资料,将所有资料导入Excel 2003,建立数据库。用SPSS 11.0进行统计分析。结果苏南地区流动人口活动性肺结核病人数4年期间增加了77.0%,年递增21.0%,而同期当地人口活动性肺结核病人数减少了32.9%。流动人口中15~54岁肺结核病人占流动人口总病人的89.0%,而55岁及以上只占10.8%;本地人口中15~54岁肺结核病人只占总病人数的52.1%,而55岁及以上占47.6%。流动人口肺结核患者系统管理率为94.7%、成功治疗率为92.0%,明显低于当地人口,但流动人口患者的丢失率为2.3%,明显高于当地人口。4年间苏南3市总的肺结核病人数量下降了5.3%,下降幅度明显低于江苏省其他地区的15.4%;但是本地人口活动性肺结核病人数4年期间减少了32.9%,其下降的幅度明显高于江苏省其他地区。结论流动人口肺结核患者的增加是苏南地区肺结核数量居高不下的主要原因。应该采取切实措施,控制流动人口肺结核疫情的发展势头。
Objective To analyze the epidemiological characteristics and trend of tuberculosis in floating population in southern Jiangsu Province and explore the influence of floating population on the epidemic situation of pulmonary tuberculosis in our country and provide a scientific basis for the prevention and control of tuberculosis among floating population. Methods Data of monitoring reports and medical records of floating population and local population from 2007 to 2010 in 3 cities in southern Jiangsu were collected and all the data were imported into Excel 2003 to establish a database. Statistical analysis was performed using SPSS 11.0. Results The number of TB patients in floating population in southern Jiangsu Province increased by 77.0% over the 4-year period, up by 21.0% year-on-year, while the number of local population with active TB decreased by 32.9% over the same period. Of the floating population, tuberculosis patients aged 15-54 accounted for 89.0% of the total floating population compared with 10.8% for those aged 55 and over. Among the local population, tuberculosis patients aged 15-54 accounted for only 52.1% of the total number of patients, while those aged 55 and Above accounted for 47.6%. The systematic management rate of floating TB patients was 94.7% and the successful treatment rate was 92.0%, which was significantly lower than that of the local population. However, the floating rate was 2.3%, which was significantly higher than that of the local population. The total number of TB patients in 3 cities in southern Jiangsu decreased by 5.3% in 4 years, a significant decrease compared with 15.4% in other parts of Jiangsu Province. However, the number of local population with active pulmonary TB decreased by 32.9% during the 4-year period, with a significant decrease Higher than other parts of Jiangsu Province. Conclusion The increase of tuberculosis patients in floating population is the main reason for the high number of pulmonary tuberculosis in southern Jiangsu. Practical measures should be taken to control the development momentum of the TB epidemic among migrants.
