MORALES, Adaucio y MONTILVA, Mariela. Clinical-metabolic profile related to cardiovascular risk in school adolescents from Barquisimeto , Venezuela. An Venez Nutr [online]. 2012, vol.25, n.2, pp.55-63. ISSN 0798-0752.
To determine the clinical - metabolic profile related to cardiovascular risk among adolescent students, of both sexes, from Barquisimeto. The study was carried out on 500 adolescents between 15 and 19 years old (253 men and 247 women). The selection was carried out in two stages: a) Stratified random sampling of 18 secondary schools and 3 universities and b) Non-probabilistic accidental sampling of adolescents in such institutions. The body mass index, blood pressure, lipid profile, glycemia, and insulin resistance according HOMA-IR were evaluated. There were statistically significant differences between sexes, in all the variables except in body mass index, LDL -Cholesterol and glycemia. The prevalence of clinical -metabolic alterations were: Excess weight (21.2%), insulin resistance (20.4%), low HDL cholesterol (17.7 %), total hypercholesterolemia (16%), high LDL cholesterol (14.5 %), hypertriglyceridemia (14.2%), hypertension (1.8%) and hyperglycemia (0.2%); 22.4% presented two or more clinical-metabolic alterations and (9.6%) three or more. There were just statistically significant differences in the prevalence of excess weight, low HDL cholesterol and hypertriglyceridemia, which were higher in men, with a ratio of 1.6 (CI95% 1.1 - 2.2); 2.1 (CI95% 1.4 - 3.2) and 1.7 (CI95% 1.1 - 2.7), respectively. A high prevalence of clinical - metabolic alterations was found with increased risk of being overweight, low HDL - C and hypertriglyceridemia in men, which merits attention of health authorities in the region.
