ABSTRACT
AIM:
To examine the correlation between inflammatory biomarkers and plasma ß-carotene levels in children.METHODS:
A total of 564 Spanish schoolchildren aged 9-12 were observed and studied. Plasma ß-carotene levels were assessed by HPLC. A ß-carotene level <4.83 µg/dL (0.09 µmol/L) was considered deficient. Plasma tumour necrosis factor-α (TNF-α) and interleukin-6 (IL-6) were measured by immunoenzyme assays. Serum high-sensitivity C-reactive protein (hs-CRP) was tested by immunonephelometry.RESULTS:
Subjects who were ß-carotene-deficient (23.1% of the studied children) had higher IL-6 levels than subjects with normal ß-carotene concentrations. The log-IL-6 and log-hs-CRP concentrations, but not the log-TNF-α level, were strongly and inversely related to the plasma log-ß-carotene level (taking into account log-age, energy intake, log-triglycerides, gender, log-body mass index, log-ß-carotene intake, energy from lipids and cholesterol as covariables). When the 3 inflammatory biomarkers were introduced into the regression model along with the corresponding covariables, only the log-IL-6 level was related to the plasma log-ß-carotene level (ß = -0.505 ± 0.078; p < 0.001).CONCLUSIONS:
Inflammatory status, in particular IL-6 levels, appears to be negatively associated with plasma ß-carotene levels in schoolchildren.Key words
