The obesity prevalence and its interrelations with cardiovascular risk in Mongolian urban employed population

Purpose: to study the prevalence of obesity and identify its markers closely related with cardiovascular risk increase among urban employed Mongolians. Methods. The anthropometry and body bioimpedance analysis were carried out in 1277 railway workers aged 18-63. Blood pressure, lipids and fasting plasma glucose levels were measured. 10-year risk for cardiovascular events was calculated. Results. The prevalence of general obesity was 65.4 % in men and 68.5 % in women. Abdominal obesity was found in 58.5 % of men and 76.1 % of women. The 10-year risk for cardiovascular events by the SCORE (Systematic Coronary Risk Evaluation), FHS (Framingham Heart Study) and ASCVD (Atherosclerotic Cardiovascular Disease risk) algorithms were assessed as well as proportions of men and women at elevated/high cardiovascular risk were determined. The obesity-related markers with the best diagnostic accuracy for elevated/high cardiovascular risk were revealed by ROC-analysis. For men they were waist circumference waist-to-height ratio, for women - the body fat percentage. The optimal cutoff values for these predictors and corresponding odds ratios for risk increase were determined.
