Background: Obesity has been associated with low-grade systemic inflammation, potentially leading to insulin resistance, type 2 diabetes, dyslipidemia, and cardiovascular diseases. Even moderate weight loss through dietary changes and physical exercise is effective in preventing and managing obesity-associated disorders. The aim of this study was to determine the effect of weight loss in response to a lifestyle modification on the serum levels of inflammatory markers in obese children and adolescents.
Material and methods: Fifty obese subjects completed a six-month programme consisting of combined hypocaloric diet and moderate physical activity. High-sensitive C-reactive protein (CRP), interleukin-6 (IL-6), fibrinogen (FB), white blood count (WBC), glucose, insulin, insulin resistance index (HOMA IR), glycosylated haemoglobin (HbA1c), lipids as well as systolic (SBP) and diastolic blood pressure (DBP) were measured before and after intervention.
Results: Patients had a 5.3 ± 3.4 kg average weight loss, with significant decreases of SDS-BMI, percentage of body fat, SDS-waist, SBP and DBP, HOMA-IR, HbA1c and reductions in serum IL-6, CRP, WBC, FB. In the multivariable linear models, changes in percentage of body fat and HOMA-IR were positively associated with favourable changes in inflammatory parameters.
Conclusion: This study demonstrates that weight reduction after successful lifestyle intervention results in improvements of blood inflammatory markers in obese children and adolescents. (Pol J Endocrinol 2011; 62 (6): 499–505)
