© 2016 Sociedad Colombiana de Cardiología y Cirugía CardiovascularObjective To determine prevalence of visceral fat volume estimated by means of a predictive equation in an adult group in Bogota, Colombia, as well as to assess the relationship between visceral fact and risk factors associated to cardiovascular disease. Material and methods Cross-sectional study of 413 volunteer men working in the education and automotive sectors in Bogota, Colombia. Visceral fat volume was estimated with a predictive equation and results were divided into tertiles of visceral fat volume. The following values were measured: body mass index, waist circumference, wast-to-height ratio, body adiposity index, systolic, diastolic and average blood pressure, total cholesterol, triglycerides, HDL-c, LDL-c and glucose. Following ratios were calculated: TC/HDL-c, LDL-c/HDL-c, TG/HDL-c and lipid and metabolic index. Results Participants’ average age was 30.6 ± 11.8 (CI 95%; 29.4-31.7 years) and prevalence of visceral obesity was of 34.6%. Individuals with a lower volume of visceral fat (tertile 1) showed better TC levels (tertiles 1 o 3, 156.4, 168.6 y 202.0; p <0.001 linear), lower TG/HDL-c ratio (2.0, 2.8 y 5.2; p <0.001 linear), lower TC/HDL-c ratio (3.3, 3.8 y 4.7; p <0.001 linear) and a healthier lipid and metabolic index (0.73, 0.44 y -0.68;p <0.001 linear). Participants with a higher volume of visceral fat (tertiles 2 and 3) showed a positive and significant correlation with body mass (r = 0.261), WC (r = 0.484), BAI (r = 0.188), WHR (r = 0.551), TC (r = 0.531), TG (r = 0.422), LDL-c (r = 0.389), LDL-c/HDL-c (r = 0.216), TC/HDL-c (r = 0.374) and TG/HDL-c (r = 0.393), p <0.001. Conclusion A high prevalence of visceral obesity and a positive correlation with risk factors associated to cardiovascular disease were verified.
