↵* Hypertension defined as systolic or diastolic blood pressure greater than the 95th percentile of the sample age, gender and height specific blood pressures or greater than 130/85 mm Hg.
↵† Independent two sample t test comparing the means using pooled variance.
↵‡ Peripheral skinfold thickness is the sum of the biceps and triceps skinfold thicknesses.
↵§ Central skinfold thickness is the sum of the subscapular and suprailiac skinfold thicknesses.
↵¶ The sum of four skinfold thicknesses, Σ4SF, is the sum of biceps, triceps, subscapular and suprailiac measurements.
BMI, body mass index; HbA1c, haemoglobin A1c; HDL, high-density lipoprotein; LDL, low-density lipoprotein.
