Brief Summary

Obesity is a problem of ever-growing importance, especially in industrialized countries, both in adults and in the pediatric population. Children and obese adolescents, like adults, have an increased risk, compared with normal-weight peers, to develop metabolic syndrome and atherosclerotic disease, pathophysiological basis of cardiovascular events. Alteration of the elastic properties of the arteries has been described previously in obese children and adolescents and is considered an initial marker of atherosclerotic vascular damage. The determination of the indices of arterial stiffness (PWV, Pulse Wave Velocity; AI, Augmentation Index, SI, Stiffness Index) is possible through techniques currently used for the determination of vascular function even in children. Nuts and hazelnuts are rich in potentially beneficial substances including unsaturated fatty acids, especially omega-6 (present in both) and omega-3 (present only in nuts), Several clinical trials have already shown in adults a potential beneficial effect of the addition of different types of nuts (walnuts, hazelnuts, cashews, pistachios, etc.) on the characteristics of the metabolic syndrome also through their possible antioxidant effect and vasoactive. In children, some epidemiological studies have associated with a higher consumption of nuts reduced risk of hypertension, dyslipidemia, obesity and fasting glucose. The study will be conducted with a randomized design with two arms in parallel with blinded operator. The main objective of this study is to assess the efficacy of 15 grams of nuts and 15 grams of nuts a day in addition to a low calorie diet on the content of erythrocyte membranes of alpha-linolenic acid three months after the beginning of the trial in a group of obese children. Secondary objectives are to evaluate the efficacy of walnuts and hazelnuts in improving the systolic and/or diastolic blood pressure values, lipid profile, glucose and fasting insulin, vascular function.

Outcome Measures

Primary Outcomes (1)

  • ALA change

    Primary outcome is to compare percentage of fatty acids in erythrocyte membranes (in particular alpha-linolenic acid, ALA) with the content of other membrane-bound fatty acids. It will be compared in the two groups the ALA delta (delta%) between measurement at baseline compared to post-treatment (ie, after 3 months of treatment).

    baseline compared to post-treatment (ie, after 3 months of treatment)

Secondary Outcomes (19)

  • LA change

    baseline compared to post-treatment (ie, after 3 months of treatment)

  • ABPM change

    baseline compared to post-treatment (ie, after 3 months of treatment)

  • OFFICE BLOOD PRESSURE change

    baseline compared to post-treatment (ie, after 3 months of treatment)

  • HDL-cholesterol change

    baseline compared to post-treatment (ie, after 3 months of treatment)

  • triglycerides change

    baseline compared to post-treatment (ie, after 3 months of treatment)

  • +14 more secondary outcomes
