Recent studies have shown that C-reactive protein is not just an indicator of cardiovascular disease (CVD) incidence and mortality. Thus, early detection of a continous increase in CRP concentrations may be useful in predicting subsequent development of CVD or metabolic syndrome.
The objective of this study was to analyze high sensitivity C-reactive protein (hs-CRP) in apparently healthy young Korean adolescents and determine confounding factors for high hs-CRP in this population.
We enrolled 197 middle school students (93 boys and 104 girls) who participated in a general health check-up at a tertiary hospital in Seoul. We measured height, weight, waist circumference and blood pressure and investigated hs-CRP concentrations, insulin levels, insulin resistance and lipid profiles. Hs-CRP levels were measured using the Behring BN II nephelometer (Dade Boering, Marburg, Germany) and log-transformed for analysis.
hs-CRP concentration was significantly higher in boys than in girls (P=0.012). Pearson’s correlation coefficients revealed a significant correlation between log- transformed hs-CRP and BMI (r=0.24, P=0.0008), waist circumference (r=0.24, P=0.0007), systolic (r=0.17, P=0.019) and diastolic blood pressure (r=0.23, P=0.014), and ALT (r=0.16, P=0.023). In stepwise multivariate linear regression analysis, sex (male gender), waist circumference, and diastolic blood pressure were positively and fasting serum HDL-cholesterol level was negatively associated with log-transformed hs-CRP.
We found that there exists a gender difference in hs-CRP concentrations in apparently healthy adolescents and that log-transformed hs-CRP concentrations were positively associated with male, waist circumference and diastolic blood pressure and negatively associated with HDL-cholesterol level. The gender difference and the contibuting factors for hs-CRP found in these healthy adolescents suggests a possibly relevant pathophysiological mechanism involved in the increase of cardiovascular risk associated with childhood obesity.
