Seasonal Variation in Type 1 Diabetes Incidence in Poland: Exploring the Impact of Viral Infections, Including COVID‐19
Authors' conclusion
These findings underline the complex interplay between viral infections and T1D seasonality
Study context
- Population
- Children with newly diagnosed T1D admitted to two pediatric diabetes centers in the Masovian Voivodeship, Poland, 2015–2023
- Participants
- 2,381 children
- Exposure
- T1D onset in autumn-winter vs spring-summer; correlation with COVID-19 and influenza cases
- Outcome
- Seasonal pattern of T1D onset
Methodological detailstwo pediatric diabetes centers
- Two pediatric diabetes centers
Main finding
As reported in the abstract
T1D onset by season
P < 0.0001
- Increase in T1D cases over study period
- 30%
Observational data: associations, not effects.
Further findings
Seasonal pattern in children <4 years
- Distinct pattern with a peak in October
Correlation of T1D incidence with COVID-19
- First wave: strong association, r
- 0.96 (p < 0.001)
- Second wave: no correlation, r
- 0.086 (p = 0.87)
Correlation of T1D seasonality with influenza infections
- Close correlation, r
- 0.79 (p = 0.002)
- Overall trends differed
