【摘要】：目的探讨人口流入城市肺结核流行特征、时空聚集性及社会影响因素。方法通过中国疾病预防控制信息系统收集宁波市2013-2015年肺结核发病数据,并进行描述流行病学分析。使用SaTScan9.1.1对街道/乡镇级发病数据进行时空扫描分析。利用ArcMap10.2对分析结果进行可视化展示。结果宁波市2013-2015年累计报告肺结核12 109例,发病率呈逐年下降趋势,外地户籍病例占比逐年上升。男女比例为2.07∶1(8162/3947),各年龄组均有发病,其中15-34岁、65岁及以上发病率高,15-54岁年龄组占比73.95%,职业分布以农民、家政家务及待业、民工、工人为主。时空聚集性扫描共发现6个聚集区,其中一类聚集区分布在中心城区及其周边,二类聚集区分布在工业园区。与非聚集区相比,发病聚集区的流动人口占比(t=2.88,P=0.01)、省外流入人口占比(t=7.46,P=0.00)、人口密度(t=3.37,P=0.00)均较高,而人均公园绿地面积较低(t=-2.39,P=0.03)。结论人口流入城市的中心城区及其周边、工业园区是肺结核疫情高发区和聚集区。人口密度和流动人口高是发病聚集的重要影响因素。
[Abstract]:Objective to investigate the epidemic characteristics, temporal and spatial aggregation and social influence factors of pulmonary tuberculosis (TB) in urban areas. Methods the data of pulmonary tuberculosis incidence in Ningbo from 2013 to 2015 were collected through China Disease Control and Prevention Information system. SaTScan9.1.1 was used to analyze the incidence data of street / township level in time and space. ArcMap10.2 was used to visualize the results. Results 12 109 cases of pulmonary tuberculosis were reported in Ningbo from 2013 to 2015. The incidence rate was decreasing year by year, and the proportion of household registration cases in other areas was increasing year by year. The ratio of male to female was 2.07: 1 / 8162% 3947%. The incidence rate was found in all age groups, including those aged 15-34 years, 65 years old and above, and 73.95% of the age group aged 15-54 years. The occupation was distributed among farmers, domestic workers and unemployed workers. Migrant workers and workers are the main workers. In total, 6 gathering areas were found by space-time aggregation scanning, of which one was located in and around the central urban area, and the other was in the industrial park. Compared with the non-concentrated area, The proportion of floating population is 2.88%, the proportion of inflow population is 7.46%, the population density is 3.37%, and the per capita area of park green space is lower. Conclusion the population flows into the central city of the city and its surrounding areas. The industrial park is a high incidence and concentration area of tuberculosis, and the high population density and floating population are the important factors influencing the incidence and accumulation of tuberculosis.
