Several preliminary medical reviews of coronavirus cases indicate that obesity is a significant determinant of severe infections of the disease, shedding further light on why some individuals and not others are particularly stricken by COVID-19.
Researchers out of New York University and Cornell University have observed elevated cases of the illness in patients with higher body-mass indexes. Only old age was a more consistent predictor of severe cases.
Notably, scientists have tentatively found that obesity itself, and not the underlying conditions that often come with being severely overweight, qualifies as a major risk factor. Patients with underlying symptoms of any kind make up the vast majority of severe coronavirus cases and deaths.
