A clinical study confirmed that obesity increased the risk of hospitalization, intensive care admission, mechanic ventilation requirement, and death among children and adolescents with COVID-19 (39) and another study proved that obesity is associated with an increased risk of COVID-19 mortality due to the interaction of adipocytes with angiotensin-converting enzyme 2 (ACE2) and interleukin 6 (IL-6) (40); the outbreak had exacerbated the overweight and obesity prevalence among students of all school-ages due to social isolation and e-learning (41). This evidence concerns the gene ACE2 and obesity due to melanocortin 4 receptor deficiency.
