Circulating inflammatory biomarkers and academic performance in adolescents: DADOS study.


ABSTRACT: OBJECTIVE:The present study aimed (1) to examine the association between circulating inflammatory biomarkers and academic performance in adolescents, and (2) to identify the ability of circulating inflammatory biomarkers to predict low academic performance. METHODS:A total of 244 adolescents (13.9±0.3 years, 112 girls) from the DADOS study were included in the analysis. Four inflammatory biomarkers were quantified: white blood cell (WBC) count, interleukin-6, tumor necrosis factor-? (TNF-?), and C-reactive protein (CRP). Academic performance was assessed through academic grades and the Spanish version of the Science Research Associates Test of Educational Abilities. RESULTS:TNF-? was inversely associated with math, Spanish and grade point average (? ranging from -0.166 to -0.124; all p<0.05), while CRP was inversely associated with verbal ability (? = -0.128; p<0.05). Overall, receiver operating characteristic (ROC) curves analyses showed discriminatory ability of WBC and TNF-? in identifying low academic performance (all p<0.05). Moreover, logistic regression analyses indicated that students with levels of WBC and TNF-? above the ROC cut-offs values showed between 78% to 87% increased likelihood of lower academic performance (p<0.05). CONCLUSIONS:Our findings suggested that some circulating inflammatory biomarkers were associated with academic performance in adolescents. Further larger longitudinal and interventional studies are needed to clarify the short-term and long-term relationship between inflammation and academic performance in youths.
