Metabolic Syndrome Clinical Trial
— CardMetSObOfficial title:
Complex Assessment and Monitoring of Cardio-metabolic Risk in Overweight and Obese Children
Metabolic and cardio-vascular complications can often appear in overweight and obese children from an early age. Currently, there are few studies in the specialized literature that correlate clinical, biological and ultrasound parameters in order to stratify cardio-metabolic risk in obese children. Also, the specialized literature is poor regarding longitudinal follow-up and the importance of diet for reducing metabolic and cardiovascular complications in these children. This study is designed to assess the hypothesis that the sustained improvement of lifestyle with regard to nutrition and exercise can reverse cardiometabolic multimorbidities in obese children as assessed by clinical, biological and ultrasound evaluation.

Primary | Changes from Baseline Body Mass Index in Overweight or Obese Children after Physical Activity and Diet Interventions | Initial measurement of the body mass index (BMI) followed by three additional measurements at 3,6 and 12 months will be performed. These aim to assess the changes from baseline body mass index (BMI) in overweight or obese children, after physical activity and diet interventions.
Overweight and obesity are defined using age-specific BMI reference guidelines from the 2000 Centers for Disease Control and Prevention Child Growth Charts. Thus, overweight assumes BMI values between the 85th and 95th percentiles, and obesity implies values above the 95th percentile. |
0,3,6 and 12 months | |
Primary | Changes from Baseline Systolic Blood Pressure in Overweight or Obese Children after Physical Activity and Diet Interventions | Initial evaluation of systolic blood pressure followed by three reevaluations at 3,6 and 12 months will be performed. These aim to assess the changes from baseline systolic blood pressure in overweight or obese children, after physical activity and diet interventions.
Arterial hypertension is diagnosed as a blood pressure value (systolic, diastolic or both), measured in mmHg, over the 95th percentile for age. |
0,3,6 and 12 months | |
Primary | Changes from Baseline Diastolic Blood Pressure in Overweight or Obese Children after Physical Activity and Diet Interventions | Initial evaluation of diastolic blood pressure followed by three reevaluations at 3,6 and 12 months will be performed. These aim to assess the changes from baseline diastolic blood pressure in overweight or obese children after physical activity and diet interventions.
Arterial hypertension is diagnosed as a blood pressure value (systolic, diastolic or both), measured in mmHg, over the 95th percentile for age. |
0,3,6 and 12 months | |
Primary | Evaluation of Changes in Health-Related Quality of Life in Children diagnosed with Overweight or Obesity after Physical Activity and Diet Interventions, using the Pediatric Quality of Life Inventory (PedsQL) | The questionnaire has 23 items and undertakes the four types of functioning: physical, emotional, social, and educational. It can be filled in by children as well as parents. Higher scores indicate better health-related quality of life.
PedsQL will be used at the child's first assessment and reapplied at each control visit. Items on the PedsQL Generic Core Scales are reverse scored and transformed to a 0-100 scale. Higher scores indicate better health related quality of life: 0 ("Never") = 100 ("Almost Never") = 75 ("Sometimes") = 50 ("Often") = 25 ("Almost Always") = 0 Scale scores are computed as the sum of the items over the number of items answered (to account for missing data). If more than 50% of items or more are missing, the Scale Score should not be computed. |
0,6 and 12 months | |
Primary | Evaluation of Changes in Individual Self-Esteem in Children diagnosed with Overweight or Obesity after Physical Activity and Diet Interventions, using the Rosenberg self-esteem scale | This scale is composed of 10 questions and measures positive and negative feelings about the self. The answer range is from strongly agree to strongly disagree.
The scale ranges from 0-30. Scores between 15 and 25 are within normal range; scores below 15 suggest low self-esteem. |
0,6 and 12 months | |
Secondary | Ultrasound Evaluation of Changes in Liver Echogenicity in Children diagnosed with Overweight or Obesity after Physical Activity and Diet Interventions | Initial ultrasound evaluation of liver echogenicity followed by three reevaluations at 3,6 and 12 months will be performed. These aim to assess changes in liver echogenicity and the reduction in hepatic steatosis grade, if diagnosed at onset, in overweight or obese children after physical activity and diet interventions.
Non-Alcoholic Fatty Liver Disease (NAFLD) can be diagnosed on ultrasound based on some suggestive parameters: diffuse hyperechoic structure ("bright liver"), deep beam attenuation, liver-to-kidney contrast, bright vessel walls. Non-Alcoholic Fatty Liver Disease (NAFLD) classification: Grade 1 (mild): diffuse increase in liver echogenicity, with normal visualization of intrahepatic vessels and of the diaphragm. Grade 2 (moderate): blurred visualization of intrahepatic vessels and of the diaphragm. Grade 3 (severe): intrahepatic vessels, diaphragm and the posterior region of the liver cannot be visualized. |
0,3,6 and 12 months | |
Secondary | Ultrasound Evaluation of Changes in Visceral-to-Subcutaneous-Fat Ratio in Children diagnosed with Overweight or Obesity after Physical Activity and Diet Interventions | Initial ultrasound measurement of visceral and subcutaneous fat followed by three reevaluations at 3,6 and 12 months will be performed. These aim to assess changes in visceral-to-subcutaneous-fat ratio in overweight or obese children after physical activity and diet interventions.
Subcutaneous fat thickness (ScFT) is defined as the measurement from the skin-fat interface to the anterior aspect of the linea alba. Visceral fat thickness (VFT) is defined as the thickness from the linea alba to the anterior wall of the aorta. |
0,3,6 and 12 months | |
Secondary | Changes of Carotid Intima-Media Thickness (CIMT) in Children diagnosed with Overweight or Obesity after Physical Activity and Diet Interventions | Initial ultrasound measurement of the carotid intima-media thickness (CIMT) followed by three reevaluations at 3,6 and 12 months will be performed. These aim to assess changes in carotid intima-media thickness in overweight or obese children after physical activity and diet interventions.
At every visit four measurements of CIMT at far wall of the common carotid artery, approximately 1 cm proximal to the bulb, in the end-diastolic phase (2 for the left and 2 for the right CCA) will be obtained. |
0,3,6 and 12 months | |
Secondary | Changes from Baseline Serum Glucose Levels in Overweight or Obese Children after Physical Activity and Diet Interventions | Initial evaluation of glucose levels followed by three reevaluations at 3,6 and 12 months will be performed.

0,3,6 and 12 months | |
Secondary | Changes from Baseline Serum Lipid Levels in Overweight or Obese Children after Physical Activity and Diet Interventions | Initial evaluation of serum lipid levels followed by three reevaluations at 3,6 and 12 months will be performed. These aim to assess the changes from baseline serum lipid levels in overweight or obese children after physical activity and diet interventions.
Dyslipidemia is defined if triglyceride or total cholesterol levels exceed the 95th percentile for age and sex or if or high-density lipoprotein (HDL) cholesterol levels are below the 5th percentile for age and sex. |
0,3,6 and 12 months | |
Secondary | Changes from Baseline Liver Function Tests in Overweight or Obese Children after Physical Activity and Diet Interventions | Liver function will be assessed by determining serum levels of alanine aminotransferase (ALT or TGP) (U/L) and gamma glutamyl transferase (GGT) (U/L) at the initial evaluation, and again at 3, 6 and 12 months.
