以前的研究表明,1型糖尿病可能具有感染性起源。时间群集的存在下,不规则的时间分布的情况下,将提供额外的证据表明,发生可能与代理,显示mammicity。我们测试的存在和形式的时间聚类使用人口为基础的数据从英格兰东北部。该研究分析了1990-2007年期间被诊断为1型糖尿病的0-14岁儿童的数据,这些儿童居住在英格兰东北部的一个特定地理区域(诺森伯兰、泰恩河畔纽卡斯尔和北泰恩赛德)。使用Potthoff-Whittinghill方法的修改版本,通过诊断时间进行时间聚类测试。该研究分析了468例被诊断为1型糖尿病的儿童。在几个月和更长的时间间隔内,有高度统计学显著的时间聚集证据(p<0.001)。年内的集群没有表现出一致的季节性模式。这项研究增加了越来越多的文献,支持感染因子参与儿童1型糖尿病的病因学。具体地说,它表明,沉淀剂或代理商参与可能是一种感染,发生在“小流行病”。
Previous studies have indicated that type 1 diabetes may have an infectious origin. The presence of temporal clustering—an irregular temporal distribution of cases—would provide additional evidence that occurrence may be linked with an agent that displays epidemicity. We tested for the presence and form of temporal clustering using population-based data from northeast England. The study analysed data on children aged 0–14 years diagnosed with type 1 diabetes during the period 1990–2007 and resident in a defined geographical region of northeast England (Northumberland, Newcastle upon Tyne, and North Tyneside). Tests for temporal clustering by time of diagnosis were applied using a modified version of the Potthoff-Whittinghill method. The study analysed 468 cases of children diagnosed with type 1 diabetes. There was highly statistically significant evidence of temporal clustering over periods of a few months and over longer time intervals (p<0.001). The clustering within years did not show a consistent seasonal pattern. The study adds to the growing body of literature that supports the involvement of infectious agents in the aetiology of type 1 diabetes in children. Specifically it suggests that the precipitating agent or agents involved might be an infection that occurs in “mini-epidemics”.
