title: Metabolic syndrome in adolescents in the Balearic Islands, a Mediterranean region.
abstract: OBJECTIVE
  To determine the prevalence of metabolic syndrome (MetS) and its components in adolescents in the Balearic Islands, in the western Mediterranean Sea.
  
  
  RESULTS
  A cross-sectional nutritional survey was carried out in the Balearic Islands (2007-2008). A random sample (n=362, 143 boys and 219 girls) of the adolescent population (12-17 years) was interviewed, anthropometrically measured, and provided a fasting blood sample. The MetS prevalence was determined by the ATP III criteria adapted for youths. Adherence to the Mediterranean diet (MD) was defined according to a score constructed considering the consumption of MD components: high monounsaturated fatty acids (MUFA)/saturated fatty acids (SFA) ratio, moderate ethanol consumption, high legume, cereals and roots, fruit, vegetables, and fish consumption, and low meat and milk consumption. The overall MetS prevalence was 5.8% (boys 10.5%, girls 2.7%). MetS criteria were met by 10.0% of overweight, 45.5% of obese and in 1.8% of normal weight adolescents. Half of the adolescents (49.7%) had at least one MetS component. None of the adolescents had all five risk factors. High triglyceride level (90.5%), hypertension (85.7%), low HDL cholesterol level (78.9%) and central obesity (71.4%) were common among adolescents with MetS whereas hyperglycaemia (0.6%) was infrequent. Higher adherence to MD was associated with significantly lower odds ratio of having MetS, but half of the adolescents showed high adherence to MD.
  
  
  CONCLUSIONS
  MetS prevalence was significant among adolescents in the Balearic Islands, especially among obese boys. A high adherence to MD in adolescents was associated with a low prevalence of the MetS criteria.
