Belgium

Source for 1997, 2001 and 2004 is National Health Interview Survey
(https://hisia.wiv-isp.be/SitePages/home.aspx). The surveys are nationally representative and
include persons aged 15 years and over. The prevalence is that of self-reported diabetes mellitus,
and the number of all diabetes mellitus cases was calculated by applying the prevalence from the
Health Interview Survey to the mid-year population.
Source for 2006 onwards is the health atlas of the Belgian InterMutualistic Agency (IMA-AIM);
http://atlas.ima-aim.be. The IMA-AIM ATLAS includes figures for all persons entitled to
reimbursement from the compulsory health insurance with an address in Belgium. The population of
beneficiaries corresponds to 99% of the population included in the National Register. This
population corresponds to 99% of the entire Belgian population. Small deviations may exist for
Brussels and the border communities. The source data are administrative data and billing data for
reimbursed care. In the atlas, diabetes prevalence is defined as the number of beneficiaries
receiving antidiabetics or diabetes-related products, per 1000 beneficiaries. However, it should be
noted that approximately 10-12% of diabetes patients are not on medication.

Coverage: Data are estimates based on the results of the ?German Health Interview and Examination
Survey for Adults? (DEGS1) and the ?German National Health Interview and Examination Survey 1998?
(BGS98).
Methodology: The ?German Health Interview and Examination Survey for Adults? (DEGS1) is part of the
health monitoring of the Robert Koch Institute (RKI) and is designed as a combined cross-sectional
and longitudinal survey. The aim of the study is to repeatedly provide nationally representative
data on the health status of the adult general population (18-79 years) in Germany.
In order to perform both cross-sectional and longitudinal analyses, a mixed study design was
implemented. Therefore, a sample of participants was randomly chosen from local population
registries and then supplemented by former participants of the ?German National Health Interview and
Examination Survey 1998? (BGS98) ? a previous nationwide cross-sectional study conducted by the RKI.
A nonresponse analysis and a comparison of several indicators of the study with official statistics
show a high representativeness of this net random sample for the German resident population.
The interview and examination programme comprised standardised interviews, such as a medical
interview conducted by a physician and an interview on pharmaceutical drug use, as well as
self-administered questionnaires on health and nutritional issues. Further, physical examinations
were performed (anthropometry, blood pressure, pulse, and thyroid gland volume) and blood and urine
were analysed.
The German National Health Interview and Examination Survey 1998 (BGS98) was part of the health
monitoring of the Robert Koch Institute (RKI). The aim of the survey was to collect data on the
health and health determinants of the adult general population (18-79 years) in Germany on a regular
basis.
The health data were collected in all federal states using uniform characteristics. BGS98 was thus
the first nationwide representative survey on the health status of Germany's adult population.
The BGS98, collected data required to describe health status, morbidity trends and regional
differences, including information on diseases and risk factors, health-related modes of behaviour
living conditions and the extent to which people use medical services.
BGS98 derived its health data from personal interviews and physical examinations, questionnaires and
medical or laboratory examinations forms (blood, serum, urine partly).

medical institutions with a modern laboratory equipment were opened in Lebap province in 2011, which
led to an increase in laboratory tests, including biochemical tests and determination of blood
sugar, and as a cause to an improved detection of patients with diabetes.
