Abstract

Objective: Seasonal variation in type 1 diabetes (T1D) incidence has long been a focus of epidemiological research, with viral infections among the proposed contributing factors. Our aim was to examine the seasonal pattern of T1D onset in Poland and to assess how viral infections-including COVID-19-may influence this seasonality. Methods: We analyzed data from 2381 children with newly diagnosed T1D admitted to two pediatric diabetes centers in the Masovian Voivodeship between 2015 and 2023 and compared them with epidemiological data on COVID-19 and influenza cases during the same period. Results: Our analysis revealed a 30% increase in T1D cases over the study period, with a pronounced seasonal pattern: the highest number of diagnoses occurred in February and the lowest was noted in June. Children under 4 years of age exhibited a distinct pattern with a peak in October, suggesting age-specific differences in T1D pathogenesis. Overall, T1D onset was more frequent in autumn-winter than in spring-summer, with 1294 (54%) vs. 1087 (46%) cases, respectively (p  < 0.0001). The influence of COVID-19 on T1D incidence was limited to the first wave of the pandemic. During this period, a strong association was observed (r = 0.96, p  < 0.001), whereas no correlation was found during the second wave (r = 0.086, p = 0.87). The seasonality of T1D diagnoses closely correlated with that of influenza infections (r = 0.79, p = 0.002). However, the overall trends differed, suggesting that other viruses with similar transmission patterns may contribute to the seasonality of T1D onset. Conclusion: These findings underline the complex interplay between viral infections and T1D seasonality and suggest that public health strategies aimed at mitigating severe viral infections, including vaccination, warrant further investigation for their potential role in modulating T1D onset in susceptible individuals.

波兰1型糖尿病发病率的季节性变化:探索包括COVID-19在内的病毒感染的影响
目的:1型糖尿病(T1D)发病率的季节性变化一直是流行病学研究的焦点,病毒感染是被提出的影响因素之一。我们的目的是研究波兰T1D发病的季节性模式,并评估病毒感染(包括covid -19)如何影响这种季节性。方法:我们分析2015年至2023年马索维省两家儿童糖尿病中心收治的2381例新诊断T1D儿童的数据,并将其与同期COVID-19和流感病例的流行病学数据进行比较。结果:我们的分析显示,在研究期间,T1D病例增加了30%,具有明显的季节性模式:诊断数量最多的是2月,最低的是6月。4岁以下儿童表现出明显的模式,10月份达到高峰,提示T1D发病机制存在年龄特异性差异。总体而言,T1D在秋冬发病较春夏多发,分别为1294例(54%)和1087例(46%),差异有统计学意义(p < 0.0001)。COVID-19对T1D发病率的影响仅限于大流行的第一波。在此期间,观察到强烈的相关性(r = 0.96, p < 0.001),而在第二波中没有发现相关性(r = 0.086, p = 0.87)。T1D诊断的季节性与流感感染的季节性密切相关(r = 0.79, p = 0.002)。然而,总体趋势不同,这表明具有类似传播模式的其他病毒可能导致T1D发病的季节性。结论:这些发现强调了病毒感染与T1D季节性之间复杂的相互作用,并表明旨在减轻严重病毒感染的公共卫生策略,包括疫苗接种,值得进一步研究其在易感个体中调节T1D发病的潜在作用。

期刊介绍: Pediatric Diabetes is a bi-monthly journal devoted to disseminating new knowledge relating to the epidemiology, etiology, pathogenesis, management, complications and prevention of diabetes in childhood and adolescence. The aim of the journal is to become the leading vehicle for international dissemination of research and practice relating to diabetes in youth. Papers are considered for publication based on the rigor of scientific approach, novelty, and importance for understanding mechanisms involved in the epidemiology and etiology of this disease, especially its molecular, biochemical and physiological aspects. Work relating to the clinical presentation, course, management and outcome of diabetes, including its physical and emotional sequelae, is considered. In vitro studies using animal or human tissues, whole animal and clinical studies in humans are also considered. The journal reviews full-length papers, preliminary communications with important new information, clinical reports, and reviews of major topics. Invited editorials, commentaries, and perspectives are a regular feature. The editors, based in the USA, Europe, and Australasia, maintain regular communications to assure rapid turnaround time of submitted manuscripts.
