RESUMO
Introduction: Antioxidants and unsaturated fatty acids have protective effects in obesity. Aim: We investigated the benefits of Omega-3 fatty acids associated with antioxidant vitamins in obese children. Magnesemia and calcemia were observed in relation with other metabolic parameters, before and after the treatment. Materials and methods: 60 obese children were compared with 35 normal weight children. Each obese child received daily, one pill, containing: 130mg docosahexaenoic acid, 25mg of eicosapentaenoic acid, vitamin A 200µg, vitamin D 1,25µg, vitamin E 2,5mg and vitamin C 30mg for three months. All the participants were instructed not to change their lifestyle. Results: The serum values for these minerals and for 25(OH) vitamin D were lower in obese children. The obese children had insulin resistance (HOMA-IR) and an imbalance of serum adipocytokines. In obese children, the body mass index was negatively correlated with calcemia (r=-0.34) and serum 25(OH) vitamin D (r=-0.33). The HOMA-IR was negatively correlated with magnesemia (r=-0.34) and serum adiponectin (r=-0.29). The treatment improved the mineral serum level, the insulin sensitivity and the adipocytokines levels. Conclusion: In obese children, the intake of Omega-3 fatty acids associated with antioxidant vitamins, for three months improved calcemia and magnesemia and increased insulin sensitivity.
