BackgroundPaediatric obesity and insulin resistance (IR) are potentially reversible inflammatory conditions. Long chain polyunsaturated fatty acids omega-3 (LCPUFA-3) show anti-inflammatory and metabolic properties, but their clinical efficacy is unclear. ObjectiveThe objective of this study is to evaluate whether supplementation with LCPUFA-3 for 3months reduces insulin resistance and weight to adolescents with obesity. MethodsDouble-blind trial of 366 adolescents with obesity randomly assigned to 1.2-g LCPUFA-3 (DO3) or 1-g sunflower oil (DP) daily for 3months; both groups received an energy-restricted diet. Children attended monthly for anthropometric, dietary, and clinical measurements. Basal and final blood samples were obtained to measure metabolic markers and erythrocytes fatty acids. Regression models were used for analysis. ResultsA total of 119 DO3 and 126 DP children completed follow-up. At baseline, 92% of children presented IR, 66% hypertriglyceridemia, 37% low-grade inflammation, and 32% metabolic syndrome. Despite erythrocytes LCPUFA-3 increased more in DO3 (Median differences=0.984 w/w%; 95 IC=0.47, 1.53, P<0.001), body weight, insulin, and HOMA changed similarly in both groups at the end of intervention. Adjusting for basal values, changes in weight, insulin, and HOMA was not related with supplementation. ConclusionsSupplementation with LCPUFA-3 does not affect body weight or insulin in adolescents with obesity.
