DYNAMICS OF CARDIOVASCULAR RISK FACTOR PREVALENCE IN RYAZAN REGION

Abstract

Aim. To investigate the dynamics of the prevalence of cardiovascular disease (CVD) risk factors (RFs) in men and women from a representative sample of the Ryazan Region general population.Material and methods. As a part of the epidemiological study EPOCH, a cross-sectional standardised screening of a representative sample of the Ryazan Region general population (n=2098) was performed. All respondents underwent a standardised questionnaire survey, anthropometry, and blood pressure (BP) measurement. The examination was repeated 5 years later, in 1760 participants (response rate 83,8%).Results. Over 5 years, the prevalence of arterial hypertension (AH) in the urban population increased from 34,8% to 39,1% (p<0,05). In the whole sample, AH prevalence remained stable (39,3% and 36,6% at the second and first screening, respectively), similar to the prevalence of diabetes mellitus (DM) (4,5% and 3,4%, respectively). Smoking prevalence in urban women increased from 6,0% to 9,2% (p<0,05) and did not change in men (51,8% in 2002 and 49,6% 5 years later). The prevalence of excessive alcohol consumption decreased from 7,7% to 5,6% (p<0,01), while the prevalence of excessive salt consumption remained the same. Obesity prevalence increased in women (from 23,6% to 28,3%; p<0,001) and only slightly changed in men (11,7% in 2002 and 14,0% 5 years later; p=0,68). Awareness of CVD in family history increased from 46,7% to 59,8% (p<0,001).Conclusion. In a representative sample of the Ryazan Region general population, the prevalence of CVD RFs remained high over 5 years of the follow-up.
