WHO BMI-for-age girls) for obese children.\n\nThe secondary objective of the study is to characterize the microbiota profile of the study patients and to test the algorithm under development built from the integration of diet and and gut microbiota composition data that were obtained during the previous observational study NUTRI-T1D.', 'detailedDescription': 'Randomized, multicenter, 2-arm, parallel-group, single-blind controlled clinical trial (1:1 allocation ratio) with 1 group of patients with obesity (N=20) or type 1 (n=20) treated with standard obesity treatment diet or usual diet (diabetic children) and 1 group (N=20 for obesity and (N=20 for type 1 diabetes) treated with the same diets to which nutritional advice derived from microbiota analysis (NUTRI-DIET) will be added.\n\nThe study will last 12 months with an intervention phase (personalized diet) lasting 3 months.\n\nThe research includes an enrollment phase that may extend up to 9 months depending on the number of patients enrolled. The enrollment phase will be considered finished once a total of 80 patients (i.e., 40 pediatric patients with type 1 diabetes and 40 obese pediatric patients) are enrolled. During the patient enrollment phase, relevant clinical information (biological samples as faeces, urines and blood and questionnaires on diet habits, physical activity and stress) will be collected concurrently. Tests will be performed once enrollment is completed on samples from all patients collected at the time of enrollment (microbiota analysis on stool, metabolome analysis on stool and urine, serological gut barrier markers analysis on serum). Obese and/or diabetic children will be randomized to the intervention or control group. Randomization will be done according to age (≤12: \\>12), gender and pathology (diabetes or obesity).'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT'], 'maximumAge': '18 Years', 'minimumAge': '8 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.
