【Abstract】 The method for analysing geographic clusters of disease is described in this paper,using the data on age-adjusted cancer mortality rates for some common sites in 107 streetregions of Shanghai urban areas during the period 1972-1979. This method can provideobjective statistical criteria for identifying clusters. The cancer mortality rates for esophageal, stomach and liver cancers in males wereclustered with highly statistical significance in Shanghai urban area, while in females therates for esophageal, breast and ovarian cancers were significantly clustered. The geogra-phic distribution of street regions with relatively high or low cancer mortality ratesimplicates that the clusters may be related to the previous economic, cultural conditions anddietary habits of the residents. Some comments on the application of the method for analys-ing geographic clusters are made.更多还原
