Controlling body weight in youth may be key in preventing high Creactive protein

Controlling body weight in children may be important in preventing high C-reactive protein levels.

“C-Reactive protein (CRP) is an independent risk factor for atherosclerotic coronary heart diseases (ACHD) in adults. To help prevent ACHD, it may be useful to understand risk factors during childhood. The objective of this study was to investigate serum CRP and its relation to other risk factors for ACHD and adipocytokines (adiponectin, IL-6, and TNF-alpha) in Japanese children,” scientists in Japan report.

“CRP, conventional risk factors for ACHD, and adipocytokines were determined in 568 children (340 boys and 228 girls, aged 7-10 yr). Serum concentrations of adipocytokines were measured by sandwich ELISA,” wrote T. Yoshida and colleagues, University Ryukyus.

Investigators determined, “Children with high CRP concentrations (highest tertile) had higher body mass index (BMI) SD scores, insulin, insulin resistance, uric acid, and adipocytokines and had more atherogenic lipoprotein profiles than other children.”

“However,” they continued, “after being corrected by BMI SD, only high-density lipoprotein cholesterol, apolipoprotein A-I, IL-6, and TNF-alpha for boys and high-density lipoprotein cholesterol, apolipoprotein B, uric acid, IL-6, and TNF-alpha for girls were significantly correlated with CRP. IL-6 was the strongest predictive variable for CRP and accounted for 26.2 and 27.7% of the variability in serum concentrations of CRP in boys and girls, respectively.

“Serum concentrations of IL-6 were partly dependent on BMI SD and TNF-alpha in both boys and girls. Although serum concentrations of CRP are partly regulated by adipocytokines and conventional risk factors for ACHD, high CRP levels were associated with atherogenic profiles of cardiovascular risk factors in children.”

The researchers concluded, “Our findings suggest that it may be important to control body weight to prevent an increase in serum CRP in children.”

Yoshida and colleagues published their study in the Journal of Clinical Endocrinology and Metabolism (Serum C-reactive protein and its relation to cardiovascular risk factors and adipocytokines in Japanese children. J Clin Endocrinol Metab, 2006;91(6):2133- 2137).
