Prevention of Diabetes in Overweight/Obese Preadolescent Children Through a Family-based Intervention Program Including Supervised Exercise; the PREDIKID Study
Background: The global pandemic obesity has led to increased risk for prediabetes and type 2 diabetes (T2D).
Objectives: (i) To evaluate the effect of a 22 weeks multidisciplinary intervention program including exercise on T2D risk in pre-adolescents with high risk to develop T2D, and (ii) To identify the profile of microRNA in circulating exosomes and in blood peripheral mononuclear cells in pre-adolescents with high risk to develop T2D and its response to a multidisciplinary intervention program including exercise.
Background: The global pandemic obesity has led to increased risk for prediabetes and type 2 diabetes (T2D).
Objectives: (i) To evaluate the effect of a 22 weeks multidisciplinary intervention program including exercise on T2D risk in pre-adolescents with high risk to develop T2D, and (ii) To identify the profile of microRNA in circulating exosomes and in blood peripheral mononuclear cells in pre-adolescents with high risk to develop T2D and its response to a multidisciplinary intervention program including exercise.
Design, participants and methods: A total of 84 children with high risk of type 2 diabetes mellitus aged 8-12 years 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). The duration of training sessions will be 90 min of exercise, 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; total and abdominal fat (dual X-ray absorptiometry); pancreatic, hepatic and visceral fat (magnetic resonance imaging); systolic and diastolic blood pressure; fasting leptin, adiponectin, fibroblast growth factor-21, fetuin-A, hs-C-reactive protein, tumor necrosis factor-alfa, interleukin (IL)-1beta and IL-6 and lipid profile; carotid intima-media thickness (ultrasonography), microRNA expression in circulating exosomes and in blood peripheral mononuclear cells (MiSeq-Illumina); functional peak aerobic capacity (cardiopulmonary exercise testing and 20m shuttle run test). Changes in dietary habits (food frequency questionnaire and two non-consecutive 24h recalls), physical activity and sleep (accelerometry); sex, age, socioeconomic status and pubertal status will be used as potential confounders.
Discussion/Conclusions: Early prevention and identification of children with high risk to develop T2D could help to reduce the morbidity and mortality associated with the disease.
