People who are overweight/obese commonly experience poorer antioxidant protection. The aim of the present study was to determine whether overweight/obesity is associated with children's selenium status. subjects were 573 Madrid schoolchildren aged 8 - 13 years. Their intake monitored via a three-day food record. Serum concentration and blood glutathione peroxidase (GPx) activity each subject also determined, as body mass index (BMI). Children excess weight (BMI>P85) had lower serum concentrations than those normal (64.6 ± 16.8 µg/L compared 75.3 12.2 µg/L; p < 0.001). (1.99 0.62 µg/kg 2.73 0.88 µg/kg; A positive correlation found between (the best being obtained when measured in µg/kg/day, r = 0.338, 0.05), while negative relationship seen all anthropometric variables recorded strongest BMI, -0.390, 0.05). Logistic regression showed risk deficiency (<70 µg/L) increase BMI [OR 1.5031 (1.3828 1.6338)] decrease 0.9862 (0.9775 0.9949)] age 0.6813 (0.5434 0.8542)] (p detected GPx (r 0.177; 0.05) but there no significant relationships any variables, excluding waist/hip ratio -0.298; 0.01). have status children weight, which can contribute poor This situation could be more evident central adiposity.
