The International Diabetes Federation (IDF) is looking for new data sources of diabetes prevalence to include in the IDF Diabetes Atlas 10th Edition to be published in 2021.
The IDF Diabetes Atlas is the authoritative source of information on the impact of diabetes for health professionals, scientists and research institutes, economists, policy-makers, and national and international agencies. The information presented in previous editions of the IDF Diabetes Atlas has been also used widely by news media, governments, and international organisations such as the World Bank and the World Economic Forum.
IDF uses data from a variety of sources in its prevalence model to generate national, regional and global estimates of diabetes prevalence. Data sources with prevalence stratified by at least three age groups are required. However, data sources that present diabetes prevalence by at least three age groups, setting (urban/rural) and sex (Female/Male) are preferred.
A systematic process is used to determine if studies can be included in the estimates. This involves scoring of research quality using the Analytic Hierarchy Process. Where there are multiple data sources for a country, those with a higher score are more likely to be selected. Full details of the process have been described previously. Studies with the following criteria have the greatest chance of being selected as primary source data:
- Studies with a large sample size, i.e. more than 5,000 people
- Nationally representative
- High response rate (greater than 60%)
- Conducted in the last 5 years
- Published in a peer-reviewed journal
- Diabetes case identification by oral glucose tolerance test (OGTT) or fasting blood glucose test
Beyond diabetes prevalence estimates, studies in the following topics are also welcome:
- Undiagnosed diabetes
- Impaired Glucose Tolerance
- Gestational diabetes and Hyperglycaemia In Pregnancy
High quality studies are welcome for all countries. Studies that have not yet been published can be included if sufficient detail of the data collection methodology is provided.
If you are aware of a diabetes prevalence data source that would help to improve the estimates, please email the details to firstname.lastname@example.org by 31 December 2020.
