Using aging population big data to develop prediction models

Introduction. With the increase of the population age worldwide, there are
more and more people living with the type 2 diabetes mellitus. Type 2 diabetes
mellitus is leading disease, causing mortality and morbidity worldwide and pre-
sents a major economic burden for healthcare systems. The aim of this study
was to develop and validate a type 2 diabetes mellitus risk prediction model.
Methods. A secondary data analysis was performed. Data from the Survey of
Health, Ageing and Retirement in Europe waves 1 to 7 collected between 2004
and 2017 were used to develop and validate prognostic models for 10-year
type 2 diabetes mellitus prediction in European countries.
Results. Sample of 16,363 participants was used to develop and validate a global
regularized logistic regression model. Model achieved an area under the receiv-
er operating characteristic curve of 0.702 (95 % CI: 0.698 – 0.706). Measured
performance of local country-specific models where an area under the receiv-
er operating characteristic curve ranged from 0.578 (0.565 - 0.592) to 0.768
(0.749 0.787). The Danish model was assessed as model with the best predic-
tion performance where body mass index was the only variable that was se-
lected in all cross-validation runs, followed by alcohol consumption in the last
six months and smoking status which were selected in 48 % and 47% of the
models.
Discussion and conclusion. Study findings demonstrate the importance of re-cali-
bration of the models as well as strengths of pooling the data from multiple
countries to reduce the variance and consequently increase the precision of
the results.
