ABSTRACT
PURPOSE: The Global Burden of Disease (GBD) study is instrumental in understanding the global distribution and impact of diseases. Accurate estimation of type 1 diabetes mellitus (T1DM) is particularly challenging due to the scarcity of primary data and their quality. This study discusses the enhancement of GBD estimates for diabetes by incorporating new data sources for Finland, a country with the highest incidence of childhood T1DM globally.
METHODS: The study is organized in four sections that reflect the phases encountered during routine peer review processes for papers from the GBD study: 1) in-depth explanation of the GBD methodology; 2) knowledge sharing of context and the available data for Finland; 3) detailed description of the data sources used to generate the GBD 2019 estimates for diabetes in Finland; and 4) suggestions of new data sources to be incorporated in subsequent estimates.
RESULTS: The incorporation of new data sources improved the accuracy of GBD Finnish estimates on T1DM, reflecting more recent trends and addressing previous uncertainties.
DISCUSSION: This study underscores the importance of collaborative data efforts and robust national health surveillance systems in enhancing global health estimates. Accurate data collection and integration into global models are crucial for informed health policy and planning.
