Prognostic Impact of the Nutritional Status of Individuals Aged 70 Years and Older With SARS-CoV-2

IPrognostic Impact of the Nutritional Status of Individuals Aged 70 Years and Older With SARS-CoV-2

Mortality due to Covid-19 is much higher in the elderly. There are several reasons for the vulnerability of the elderly to the coronavirus: a less efficient immune system, underlying chronic conditions, less protected living conditions. They may also present a poor nutritional state and/or degraded metabolic reserves aggravating an underlying state of frailty. The prevalence of the risk of undernutrition in elderly patients with COVID-19 is high. The evolution of the nutritional status of people aged 70 years or older infected with SARS-Cov-2 is not yet well known. The prognosis of these patients could depend on their nutritional status at the time of the disease. In view of the lack of data, it would be interesting to compare the risk of mortality based on nutritional status in individuals with vs. those without COVID-19.
