Table 2 Prevalence of MetS-related biochemical risk factors according to waist circumference

From: Metabolic syndrome among adolescents in Dubai, United Arab Emirates, is attributable to the high prevalence of low HDL levels: a cross-sectional study

  1. aAs classified by the IDF
  2. bAs defined by NCEP (1992) and NHANES (1994)
  3. Values are reported as frequencies (percentages): n (%)
  4. Non-parametric Chi-square tests were performed to detect differences among biochemical and waist circumference categories. Significance was set at a p-value < 0.05
  5. N.B: some categories do not add up to 100%. This is due to missing data
