Early evaluation of the metabolic syndrome in Bucaramanga, Colombia.

BACKGROUND: Metabolic syndrome (MS) is one of the conditions that increase the risk of developing cardiovascular diseases (CVD) and type-2 diabetes in the early future if it appears during childhood or adolescence. The purpose of the study to compare the MS prevalence of MS estimated in a representative sample of school-age population in Bucaramanga, Colombia, and the MS prevalence estimated in a subsample from the same population in the adolescent stage. METHODS: An analytical cross-sectional survey (in the adolescent stage) (n=494) was carried out, nested in a population-based cohort assembled when children were of school age (n=1,282). Selection employed a bi-stage randomized sampling per neighborhoods and houses across the city. Sociodemographic and anthropometric variables, as well as cardiometabolic factors were analyzed in accordance with their distribution, and statistical significance tests were applied according to each case. MS was determined using the Adult Treatment Panel III (ATP III) and International Diabetes Federation (IDF) criteria. RESULTS: Estimated MS prevalence in school age according to the ATP III criteria was 9.5% (95% CI: 8.0-11.3%) and according to the IDF criteria it was 8.0% (95% CI: 6.6-9.7%). At the time of follow up the prevalence of MS was 13.2% and 14.8% according to the ATP III and IDF criteria, respectively. CONCLUSIONS: MS prevalence of MS increased in 4% from the school age (9.5%) to the adolescence (13.1%).
