Simple, practical, non-invasive and inexpensive methods are needed to identify individuals at high risk for IGT and diabetes and to limit the proportion of the population requiring diagnostic glucose tolerance tests. IDF recommends the use of brief patient questionnaires to help healthcare professionals to quickly identify people who may be at a higher risk and who need to have their level of risk further investigated. This type of questionnaire could also be used by individuals for self-assessment.
The Finnish Type 2 Diabetes Risk Assessment Form developed in 2001 is an example of an effective patient questionnaire and should be used as the basis for developing national questionnaires which take into account local factors. It has eight scored questions, with the total test score providing a measure of the probability of developing type 2 diabetes over the following 10 years. The reverse of the form contains brief advice on what the respondent can do to lower their risk of developing the disease, and whether they should seek advice or have clinical examinations. The test takes only a couple of minutes to complete and can be done on the internet, in pharmacies or at various public campaign events.
In resource poor settings where questionnaires are not available or impractical, measurement of waist girth gives a simple prescreening tool allowing those at highest risk to be identified.
