Dietary Modulation of Gut Microbiota on Nutritional Status and COVID-19 Infection in Adolescents: Gut-Lung-Axis

INTERVENTIONAL
Conditions
Summary
Probiotic intervention has been currently suggested to provide supportive benefits in promoting health, including alleviating disease symptoms, protecting against diarrhea and respiratory infection, affecting growth and modulating the immune system by improving the beneficial gut microbiota colonization, giving direction on the gut-lung-axis pathway. This indicates that probiotics may become alternative to improve nutrition and reduce the risk of viral infections which may reduce the risk against Severe Acute Respiratory Syndrome Corona Virus-2 (SARS-CoV-2). Introduction to probiotics during adolescence can alleviate inflammation and invert dysbiosis. However, evidence on the effect of probiotic supplementation on enhancing antibody response to SARS COV-2 in adolescents is lacking. Moreover, previous studies showed the potential effect of probiotic supplementation to improve overweight and obesity in adolescents. A bi-directional relationship exists among nutrition, infection, and immunity as changes in one element will affect the others. The main objective of this study is to investigate the effect of dietary modulation of overweight and obese adolescent's gut microbiota through probiotic supplementation combined with healthy eating and physical activity counseling and psychosocial stimulation on nutritional status and antibody response to COVID-19 vaccination. This trial will conduct a 20-week intervention for overweight and obese adolescents.
