Abstract
Objective: Metabolic syndrome (MetS) and its associated cardiovascular risk are on the
increase in children. High-sensitivity C-reactive protein (hs-CRP) has emerged as a useful
marker for inflammation associated with atherosclerosis and cardiovascular disease. Our aim
was to determine the distribution of hs-CRP in an effort to identify the MetS variable that is
critical in modulating plasma CRP levels in a population of South African adolescents.
Design: A cross-sectional analytical study design was used for this investigation, where the
dependent and independent variables were measured simultaneously.
Methods: Anthropometric variables, blood pressure, fasting blood glucose and lipids were
performed on 324 consenting learners aged 15–18 years from three different ethnic groups
(Black, White and Coloured). The National Cholesterol Education Program Adult Treatment
Panel III (NCEP ATP III) for ages 15–18 year olds was used to define MetS.
Results: The prevalence of MetS and obesity was 3.7% and 7.1%, respectively. The hs-CRP
levels were significantly higher in subjects with a waist-circumference greater than the 90th
percentile (p < 0.01) and in obese learners with MetS, but was lower in adolescents with normal
weight and MetS. Median hs-CRP levels increased with an increasing number of metabolic
abnormalities and exceeded 3 mg/L in 19% of adolescents. Gender and ethnic differences were
observed.
Conclusion: Our findings suggest that obesity and waist circumference appear to be major
mediators of hs-CRP levels in South African adolescents.
