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.
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.
