The updated Vitality Age Calculator is an online tool that gives users a snapshot of their overall health based on lifestyle choices and clinical risk factors. While maintaining the core concepts of the original Vitality Age model, the new version expands the number of input factors used in the analysis, builds on a more comprehensive and consistent data source, incorporates age-related mortality, improves handling of missing data, and substantially expands the possibilities for sensitivity analysis of results. In this report, we detail the steps taken to create the model. The report includes discussion of existing mortality rate and disease risk calculators. We also present the theoretical foundations of the calculator, the collection and processing of data, and the selection of risk factors and their applicability in different geographical contexts. The calculation algorithm and its programming as well as the design of the survey accompanying the calculator are discussed.
