Aim To obtain correct evaluation of the prevalence rate of diabetes mellitus and impaired fasting glycemia (IFG) in Hungary. Method The study was performed on a nationally representative sample covered by the Hungarian General Practitioners' Morbidity Sentinel Stations Program. The source population consisted of all persons aged 20-69 years who were registered with the participating centers. The prevalence rates were adjusted to age and sex distribution of the total Hungarian population. Fasting blood samples of 1803 participants were evaluated. Response rate was 90.7%. Results In addition to 130 (7.21%) patients with established diabetes, 26 participants with newly diagnosed diabetes were found, resulting in a total crude diabetes prevalence of 8.65% (men: 11.16%; women: 6.41%; P <0.001). After weighting for age and sex, the prevalence rate of diabetes in participants aged 20-69 years should be set at 7.47% (95% confidence interval [CI], 6.26-8.69) (men: 9.49%; 95% CI, 7.52-11.46; women: 5.58%; 95% CI, 4.12-7.04). In addition to 41 (2.27%) patients with established IFG (fasting blood glucose: 6.1-6.9 mmol/L), 47 participants with newly diagnosed IFG were found, resulting in a total crude IFG prevalence of 4.88% (men: 6.11%; women: 3.78%; P = 0.022). After making corrections for weighting age and sex, the total IFG prevalence rate in participants aged 20-69 years should be set at 4.39% (95% CI, 3.44-5.34) (men: 5.52%; 95% CI, 3.99- 7.06; women: 3.33%; 95% CI, 2.19-4.47). Conclusion The prevalence rate of diabetes and IFG in Hungary is higher than previously estimated by expertsand authorities. The present data may serve as a base for comparative investigations in the future.
