Effect of omega-3 fatty acids supplementation combined with lifestyle intervention on adipokines and biomarkers of endothelial dysfunction in obese adolescents with hypertriglyceridemia

Obesity in adolescents is considered a major public health problem; combined interventional approaches such as omega-3 supplementation with lifestyle intervention (LI) might exert synergistic effects and exceed the impact of each individual strategy.

Description
Summary:Obesity in adolescents is considered a major public health problem; combined interventional approaches such as omega-3 supplementation with lifestyle intervention (LI) might exert synergistic effects and exceed the impact of each individual strategy. The purpose of the present study was to evaluate if the supplementation of omega-3 with LI could improve metabolic and endothelial abnormality in obese adolescents with hypertriglyceridemia. The study involved sixty-nine adolescents with normal weight and seventy obese adolescents with hypertriglyceridemia. All obese adolescents were applied to LI and randomly assigned to omega-3 supplementation or placebo group for 12 weeks. The obese adolescents with hypertriglyceridemia presented increased levels of leptin, retinol binding protein 4 (RBP4), selectin E (sE) and asymmetric dimethylarginine (ADMA) and decreased levels of adiponectin compared with control subjects. After 12-week intervention, omega-3 supplementation with LI decreased significantly in triglycerides, HOMA, leptin, RBP4, ADMA and sE. Moreover, omega-3 with LI displayed a significant reduction in triglycerides, ADMA and sE in comparison with LI alone. In subjects with omega-3 combined with LI assessed by multivariate regression model, the reduction in triglycerides was the only independent determinant of the decrease in ADMA. The reductions in triglycerides and HOMA were significantly contributed to the changes in sE. Our data indicated that omega-3 combined with LI in short duration significantly improved dyslipidemia, insulin resistance, abnormality of adipokines, endothelial dysfunction in comparison of LI alone, indicating the combined approach is an effective clinical and applicable strategy to control metabolic abnormality and decrease the risks of cardiovascular diseases in obese adolescents.
