Objective. The purpose of the present study was to determine the effect of body weight on blood lipid profile, insulin resistance and inflammatory biomarkers in Mexican-American children. Methods. Children (13.3 ± 0.1 year) were recruited from a local school and assigned to one of three groups as a volunteer sample: healthy weight (HW) (≥10th and <85th BMI percentile; n = 42), at risk of overweight (RO) (≥85th and ≥95th; n = 25) or overweight (OW) (≥95th; n = 42). Plasma concentrations of hsCRP, sCD14, sIL-6R, sTNF-αR1, sTNF-αR2, IL-6 and TNF-α were determined by ELISA. Results. OW children had significantly greater plasma concentrations of hsCRP (P = 0.003), sCD14 (P = 0.013), sIL-6R (P = 0.010), sTNF-αR1 (P < 0.001), sTNF-αR2 (P = 0.005), insulin (P = 0.001), TC:HDL ratio (P < 0.001) and triglycerides (P < 0.001) than HW children. Also plasma concentrations of hsCRP, sIL-6R and sTNF-αR1 were significantly greater in OW compared with RO children. Conclusion. Overweight Mexican-American children had a higher concentration of inflammatory biomarkers than healthy weight children. To our knowledge, this is the first study to report that sCD14 is elevated in overweight compared with healthy weight Mexican-American children.
