|Abstract: ||Objective: Metabolic syndrome (MS) is on the rise in youth. As high-sensitivity C-reactive protein (hs-CRP) is associated with cardiovascular/metabolic disorders, we evaluated the association between MS and its components and hs-CRP in a sample of Brazilian overweight and obese youth.
Methods and Procedures: A total of 407 students (229 girls, 273 with excessive weight, 11.3 ± 3.2 years) were evaluated. Measurement included BMI, waist circumference (WC), blood pressure, lipids, insulin, and hs-CRP. Excessive weight was defined using BMI z -score; MS by the modified National Cholesterol Education Program—Adult Treatment Panel III.
Results: Subjects were classified into two groups: with MS (n = 72) and without (n = 335). hs-CRP means and medians were higher in MS group (1.41 mg/l vs. 1.06 mg/l, P < 0.001; 2.21 mg/l vs. 1.23 mg/l, P < 0.001). Associations between hs-CRP quartiles and insulin resistance (IR) (P < 0.001), MS (P < 0.001), WC (P < 0.000), BMI z-score (P < 0.001), hypertension (P < 0.001), hypertriglyceridemia (P < 0.001), and low HDL-c (P = 0.023) were significant; adjustment of hs-CRP for BMI z-score eliminated the previous association, except for the number of MS components (nMSc) (P < 0.001). Adjusting for homeostasis model assessment method of IR (HOMA-IR) did not eliminate the relation between hs-CRP and MS components. Furthermore, increases in BMI z -score and nMSc were associated with an increased hs-CRP. Excessive weight (odds ratio (OR), 7.9; confidence interval (CI), 4.7–13.4; P = 0.000), hypertension (OR, 2.3; CI, 1.3–4.2; P = 0.003), and hypertriglyceridemia (OR, 2.3; CI, 1.5–3.7; P < 0.001) were independently associated with hs-CRP.
Discussion: In youth, hs-CRP is strongly related with MS and its components, and is also determined by the body composition. This association indicates a precocious proinflammatory state.|
