title: The diabetes epidemic in the elderly population in Western Europe: data from population-based studies.
abstract: Valid epidemiologic data on type 2 diabetes in the elderly population are scarce in the European Region despite its enormous human and economic burden. The aim was to assess population-based data on type 2 diabetes and impaired glucose regulation (IGR) from surveys carried out in Western Europe since 1990 using oral glucose tolerance tests, and to discuss the possible impact of risk factors on geographic variation, in particular, obesity and physical activity. In the decade below 60 years of age, about 10 % of the population had known or newly diagnosed diabetes in European surveys. In the age group 70 to 79 years, average total diabetes prevalence was about one quarter. IGR prevalences also increased with age, reaching a maximum of 25 % (men) to 30 % (women) above 70 years of age. There was a wide variation of total diabetes prevalence in the elderly population in Western European countries, however, without clear geographical pattern. Whereas age- and sex-specific prevalences for total diabetes in the German KORA Survey S4 (1999/2001) (Augsburg) were comparable to the European average, IGR prevalences were higher in Augsburg (60-69 years: KORA: men: 30.2 %, women: 22.4 % Europe: men: 21.2 %, women: 19.0 %). Thus, there is a huge reservoir for future diabetes cases in the elderly population in Germany. Differences at the population level were found for obesity, nutrition, and sedentary lifestyle in Western Europe. Comparative studies on the predictive values of obesity, physical activity, and nutrition and possible interactions with genetic markers in European populations are of interest in the future.
