研究目的：由于早期的研究表明瑞典东南部地区1型糖尿病发病的时空聚集性，我们调查了该地区是否也存在糖尿病的地理聚集性。设计：在地理信息系统（GIS）中对诊断时的居住地（坐标）进行地理编码。所有在1977-1995年间被诊断为1型糖尿病的16岁以下儿童均被纳入研究。面临危险的人口是直接从相应年份和地理区域一级的人口登记处获得的。地理位置：瑞典东南部地区，包括5个县、49个市和525个教区。主要结果：各城市之间的发病率存在显著的地理差异（p . 391）
Study objective: As earlier studies have shown space-time clusters at onset of type 1 diabetes in the south east region of Sweden we investigated if there also has been any geographical clusters of diabetes in this region.Design: The place of residence (coordinates) at the time of diagnosis were geocoded in a geographical information system (GIS). All children diagnosed with type 1 diabetes up to 16 years of age at diagnosis between 1977-1995 were included. The population at risk was obtained directly from the population registry for the respective years and geographical area levels.Setting: South east region of Sweden containing 5 counties, 49 municipalities, and 525 parishes.Main results: A significant geographical variation in incidence rate were found between the municipalities (p
