Item The effect of a multidisciplinary intervention program on hepatic adiposity in overweight-obese children: Protocol of the EFIGRO study: Protocol of the EFIGRO study(2015-11-01) Medrano, M.; Maiz, E.; Maldonado-Martin, Sara; Arenaza, L.; Rodríguez-Vigil, B.; Ortega, F.B.; Ruiz, J.R.; Larrarte, E.; Diez-López, I.; Sarasúa-Miranda, A.; Tobalina, I.; Barrenechea, L.; Pérez-Asenjo, J.; Kannengiesser, S.; Manhães-Savio, A.; Echaniz, O.; Labayen, I.; GeneralesBackground: Non-alcoholic fatty liver disease is the most frequent liver abnormality observed in overweight or obese children and is strongly associated with metabolic syndrome and insulin resistance. Objectives: (i) To evaluate the effect of a 22-week multidisciplinary intervention program on hepatic fat fraction in overweight or obese children and (ii) to examine the effect of the intervention on cardiometabolic risk factors, self-esteem and well-being. Methods: A total of 160 children, 9-11 years, will be recruited by pediatricians and randomly assigned to control (N = 80) or intervention (N = 80) groups. The control group will receive a family-based lifestyle and psycho-educational program (2 days/month), while the intervention group will attend the same lifestyle education and psycho-educational program plus the exercise program (3 days/week). The duration of training sessions will be 90 min of exercise, including warm-up, moderate to vigorous aerobic activities, and strength exercises. The primary outcome is the change in hepatic fat fraction (magnetic resonance imaging, MRI). Secondary outcomes include cardiometabolic risk factors such as total adiposity (dual Xray absorptiometry), visceral adiposity (MRI), functional peak aerobic capacity (cardiopulmonary exercise testing), blood pressure, muscular fitness, speed-agility, and fasting blood insulin, glucose, C-reactive protein, alanine aminotransferase, aspartate aminotransferase, gamma glutamyltransferase, lipid profile and psychological measurements (questionnaires). All the measurements will be evaluated at baseline prior to randomization and after the intervention. Discussion: This study will provide insight in the efficacy of a multidisciplinary intervention program including healthy lifestyle education, psycho-education and supervised exercise to reduce hepatic fat and cardiometabolic risk in overweight childrenItem Prevention of diabetes in overweight/obese children through a family based intervention program including supervised exercise (PREDIKID project): study protocol for a randomized controlled trial: Study protocol for a randomized controlled trial(2017-08-10) Arenaza, Lide; Medrano, María; Amasene, María; Rodríguez-Vigil, Beatriz; Díez, Ignacio; Graña, Manuel; Tobalina, Ignacio; Maiz, Edurne; Arteche, Edurne; Larrarte, Eider; Huybrechts, Inge; Davis, Catherine L.; Ruiz, Jonatan R.; Ortega, Francisco B.; Margareto, Javier; Labayen, Idoia; Generales; GenéticaBackground: The global pandemic of obesity has led to an increased risk for prediabetes and type-2 diabetes (T2D). The aims of the current project are: (1) to evaluate the effect of a 22-week family based intervention program, including supervised exercise, on insulin resistance syndrome (IRS) risk in children with a high risk of developing T2D and (2) to identify the profile of microRNA in circulating exosomes and in peripheral blood mononuclear cells in children with a high risk of developing T2D and its response to a multidisciplinary intervention program including exercise. Methods: A total of 84 children, aged 8-12 years, with a high risk of T2D will be included and randomly assigned to control (N = 42) or intervention (N = 42) groups. The control group will receive a family based lifestyle education and psycho-educational program (2 days/month), while the intervention group will attend the same lifestyle education and psycho-educational program plus the exercise program (3 days/week, 90 min per session including warm-up, moderate to vigorous aerobic activities, and strength exercises). The following measurements will be evaluated at baseline prior to randomization and after the intervention: fasting insulin, glucose and hemoglobin A1c; body composition (dual-energy X-ray absorptiometry); ectopic fat (magnetic resonance imaging); microRNA expression in circulating exosomes and in peripheral blood mononuclear cells (MiSeq; Illumina); cardiorespiratory fitness (cardiopulmonary exercise testing); dietary habits and physical activity (accelerometry). Discussion: Prevention and identification of children with a high risk of developing T2D could help to improve their cardiovascular health and to reduce the comorbidities associated with obesity.
