The study was completed with use of a primary care electronic database of 11 million patients from 551 general practices in England. All participants were between the ages of 25 and 79 years, and patients with a known history of diabetes were excluded from study analysis.
The primary outcome of the study was incident type 2 diabetes during a 10-year period. Diabetes cases were identified from patients' computer records.
The risk tool, the QDScore, was calculated from the following variables, all of which were found to independently affect the risk for incident type 2 diabetes:
Age
Body mass index
Family history of diabetes
Smoking status
Treated hypertension
Use of corticosteroids
Diagnosed cardiovascular disease
Social deprivation, as measured by the Townsend deprivation scale
Ethnicity
