In a new study from Karolinska Institutet, researchers found that low BMI and malnutrition are risk factors for in-hospital mortality in geriatric COVID-19 patients.

These results are important as information on the groups with the highest mortality, i.e. the very old and frail patients, is underrepresented.

For example, obesity is a risk factor in COVID-19 infection in younger adults but the team instead found that low BMI and malnutrition increased the risk of in-hospital mortality in older COVID-19 patients who were mostly older than 75 years.

During the first COVID-19 wave in spring 2020 in Sweden, researchers reported that in-hospital mortality was 24% among older patients.

The risk of death was almost doubled for patients classified as frail according to the Clinical Frailty Scale (CFS) as compared to non-frail older patients.

In these patients, acute kidney injury and multimorbidity were also strong risk factors for death.

In the study, the team analyzed the associations of body mass index, and nutritional status assessed in older patients treated for COVID-19.

Data in the analysis comprised medical records of ~10 000 patients in Stockholm during the first two pandemic waves. Age range of the patients was from 65 to 105 years.

The team found that undernutrition; i.e., underweight (BMI<18.5) and low nutrition scores were related to short-term mortality in the COVID-19 patients.

No evidence was found that obesity is a risk factor in COVID-19 infection in older patients.

The finding is a reminder that nutritional status is vital to examine and to treat in older patients. This study offers evidence-based guidance for clinical work with these patients.

you people should start telling the truth about what people are dying from. most people dying have at least 3 other conditions and they are old

one thing is sure you have a 99.98 percent chance of survival if you even get covid. you have a 100% death rate if you go to the hospital. don't believe me? Look it up

the problem is our government has taken control over our medical, telling the Dr,s how they have to treat patients, A Dr. will loose his license if they prescribe Hydrochloriquen to a patient for Covid 19,just because Trump said it could be used to treat a Covid19 ,so the Democrats do what they always do is to change everything they always want to change everything cant leave anything alone ,a medication that has been approved for many years with low side effects, now it is dangerous its just because Trump recommended to use it.
