Relationship between type D personality and metabolic syndrome in general population of the Kemerovo region (results of the ESSE-RF epidemiological study)
Objective. To study prevalence of type D personality and examine the relationship with metabolic syndrome (MS) in general population of the Kemerovo region. Design and methods. A randomized sample was selected from general population in Kemerovo region within the multicentre observational trial «Epidemiology of Cardiovascular Diseases in the Regions of Russian Federation - ESSE-RF», including 1 610 subjects (response was more than 80 %). The mean age was 45,8 ± 11,9 years, gender distribution was the following: women - 918 (57 %), men - 692 (43 %). They were divided into two groups: patients with type D personality (n = 231) and patients without type D (n = 1379). Psychological status was assessed by the questionnaire DS-14. MS was defined according to the recommendations of the experts of the Russian Scientific Society of Cardiology (2009). Results. MS was detected in 406 (25,2 %) patients. The presence of type D personality was associated with the more than twofold increase in the risk of MS and its components, such as obesity and hypertension. Conclusions. Predisposition to the MS may be one of the factors explaining the association between type D personality and poorer cardiovascular prognosis.
