Brief Summary:
The objectives of the present study are: 1) to identify the intestinal and salivary microbiota associated with the presence and severity of hepatic steatosis in children (Study I: case-control study), and 2) to develop a personalized 12-week intervention program based on diet and exercise to examine its effects on the diversity and composition of the microbiota in children with hepatic steatosis (Study II: intervention study)
Detailed Description:
The MicroKid project will acts first as a case-control study (Study I) in order to identify the hepatic steatosis and intestinal and salivary microbiota in children grouped as non-overweight, obese-non-hepatic steatosis, and obese-hepatic steatosis. Then, an intervention study (Study II) will be developed for those children with obesity (i.e., obese-non-hepatic steatosis, and obese-hepatic steatosis groups).
Methodology: A total of 60 children, 8-12 years-old, will be assigned to control (non-overweight children, N= 20), obese-non-hepatic steatosis (children with obesity, but without hepatic steatosis, N=20), and obese-hepatic steatosis (children with obesity and hepatic steatosis, N= 20) groups (Study I: case-control study). The obesity and obesity + hepatic steatosis groups will attend to a 12-weeks healthy lifestyle education program (2 days/month) and home-based exercise program (minimum 3 days/week) (Study II: intervention study).
The combined intervention program for the Study II will include: i) healthy lifestyle education program focused on dietary and lifestyle guidelines for both children and parents (2 days/month, 60 min), and ii) exercise program based on high-intensity interval training which combines aerobic and resistance training (at least 3 days/week, from 38 to 44 min).
Measurements: In the Study I (i.e., case-control study), all participants will be evaluated at baseline. For the Study II (i.e., intervention study), only those participants that belongs to obese-non-hepatic steatosis and obese-hepatic steatosis groups, will be additionally evaluated after the intervention program (12-week). The following outcomes will be measured: hepatic fat fraction and abdominal adiposity (magnetic resonance imaging), intestinal and salivary microbiota, body composition (bioimpedance), cardiometabolic risk factors, liver enzymes, physical fitness (field-fitness tests), physical activity (accelerometry), sleep (accelerometry), dietary habits (24h recalls, and food frequency questionnaires), and pubertal development and sociodemographic characteristics will be measured.
