Aim and purpose
Type 2 diabetes is defined as a single disease entity regardless of the way it is diagnosed. The pre-diabetic subtypes ‘impaired fasting glycaemia’ and ‘impaired glucose tolerance’ reflect different disease processes, and it is likely that such differences are also present in individuals with type 2 diabetes. However, this remains to be documented.
Even though most clinicians recognise that type 2 diabetes is a multi-factorial disease with diverse characteristics, they have no system for treatment or prevention that acknowledges these differences in disease processes.
In this research project we aim to identify subgroups of individuals with different patterns of disease development before the onset of type 2 diabetes and diabetic complications. Our goal is that information obtained from this project can be used to tailor prevention strategies and treatment guidelines.
Design, method and theory
This on-going study uses data obtained from large-scale epidemiological studies:
1) The Whitehall II study
2) The Inter99 study
3) The ADDITION and ADDITION-PRO studies
We will use novel statistical methods (multilevel longitudinal modelling, latent class trajectory analysis, decision tree analysis) to identify subgroups at risk and patterns of risk factor development.
Individuals with obesity, pre-diabetes or diabetes.
Our goal is that clinicians will use these results to tailor prevention strategies and treatment guidelines for type 2 diabetes.
