To investigate school absenteeism before the clinical diagnosis of type 1 diabetes in children who develop the disease.
This population-based, retrospective case-control study involved all Danish children who developed type 1 diabetes and attended public schools ( = 1,338) from 2010 to 2017. Those children were matched at a 1-to-5 ratio, on the basis of sex and date of birth, to children without diabetes ( = 6,690). Case and control absenteeism were compared monthly, starting with 12 months prior to the type 1 diabetes diagnosis through 12 months after diagnosis.
Before the diabetes diagnosis (7-12 months), the mean number of days absent from school per month was 0.93 (SD 1.78) among children with diabetes and 0.93 (1.82) among control children (difference -0.004 days, 0.94). From 4 months before the diagnosis, children who developed diabetes had a statistically significant increase in absenteeism compared with control children (difference 0.24 days, < 0.05).
Children who were diagnosed with type 1 diabetes had increased school absenteeism 4 months before diagnosis.
研究儿童在临床诊断 1 型糖尿病前的缺课情况，这些儿童患有该疾病。
本研究为基于人群的回顾性病例对照研究，纳入了所有于 2010 年至 2017 年在丹麦公立学校就读且患有 1 型糖尿病的儿童（=1338 人）。根据性别和出生日期，这些儿童与无糖尿病的儿童（=6690 人）进行 1:5 的匹配。从 1 型糖尿病诊断前 12 个月开始，每月比较病例和对照组的缺课情况，直至诊断后 12 个月。
在糖尿病诊断前（7-12 个月），糖尿病患儿每月缺课天数的平均值为 0.93（1.78），对照组儿童为 0.93（1.82）（差值-0.004 天，94%）。从诊断前 4 个月开始，与对照组儿童相比，患有糖尿病的儿童缺课天数明显增加（差值 0.24 天，<0.05）。
在诊断为 1 型糖尿病前的 4 个月，儿童的缺课率显著增加。
