Prevalence of diabetes mellitus as well as cardiac and other main comorbidities in a representative sample of the adult Greek population in comparison with the general population

Abstract

BackgroundDiabetes mellitus (DM) is the most common metabolic disorder that increases the risk of cardiovascular disease by two to four times compared with the general population. There are limited data on the prevalence of heart diseases in subjects with DM in Greece. In this study, we examined the prevalence of self-reported DM as well as cardiac and other main comorbidities in a representative sample of the adult Greek population. MethodsThe target study population included 30,843 participants stratified by gender, age, and district, and this was a representative sample of the adult Greek population in 2010. A structured questionnaire was built to report the prevalence of self-reported DM and the main comorbidities in participants with and without DM. Collection of data was performed through telephone interviews. ResultsThe prevalence of self-reported DM was 6.6%. The prevalence of the main comorbidities in participants with DM vs. those without DM was as follows: heart diseases 24.0% vs. 8.9%, p<0.001; lung diseases 11.3% vs. 5.3%, p<0.001; kidney diseases 3.4% vs. 1.2%, p=0.001; liver diseases 1.4% vs. 0.7%, p=0.001; benign blood diseases 1.6% vs. 0.9%, p=0.005; and solid organ and/or blood malignancies 2.9% vs. 1.5%, p<0.001. ConclusionsThe prevalence of self-reported DM in a representative sample of the adult Greek population in 2010 was 6.6%. The prevalence of heart diseases in subjects with DM was 2.7-fold higher than the prevalence in those without DM. Diseases of the lung, kidney, liver, and blood as well as malignancies were significantly more common among participants with DM.
