In a new study, French researchers found that the risk of life-threatening coronavirus infections increases with weight.
- The longer the coronavirus pandemic persists, the more researchers will learn about risk groups *.
- It has been proven that people with chronic respiratory diseases such as asthma, smokers and the elderly with cardiovascular diseases and other pre-existing diseases are among the risk groups who are more often affected by serious illnesses.
- New studies now indicate that the risk of a severe course of the disease also increases with the body mass index (BMI) .
The stronger a person's immune system, the more successfully the body's defenses usually fight against a coronavirus infection. Previous illnesses such as high blood pressure or asthma mean that the body has a previous load that weakens the body * - and thus favors severe Covid 19 courses. Current publications suggest that a high body mass index also has a negative impact . Chinese and French researchers have found in studies that an excessively high BMI increases the likelihood of severe Covid 19 courses and even the risk of death.
Correlation between coronavirus and body weight: Too high a BMI increases the risk of severe courses
French scientists used data from 124 Covid-19 patients to analyze whether there was a connection between being overweight * and the course of the disease. In fact, the proportion of patients who had to be artificially ventilated by intubation was often conspicuously overweight. There were 85 people who had to be ventilated under anesthesia - and 56 percent of them had a BMI of over 30, another 35 percent were extremely obese with a BMI of over 35. "The need for ventilation gradually increased with body mass Index until it reached 90 percent of people with a BMI of more than 35, "says study director Arthur Simonnet:" Our data thus demonstrate a clear connection between obesity and the severity of Covid-19, "said the researcher .
The researchers conclude that obesity - a body mass index of over 30 - increases the risk of serious coronavirus infections . And even the death rate among extremely overweight people is higher than among normal or slightly overweight people. This is the conclusion of Chinese researchers who analyzed the data from 112 patients treated at the Union Hospital in Wuhan.

Obesity reduces the chance of survival in coronavirus infection
A total of 88.2 percent of patients who had not survived the coronavirus infection were therefore overweight to obese. In contrast, the proportion of overweight people who survived was only 18.9 percent, as the picture quotes the study. "COVID-19 in combination with CVD (to German: cardiovascular diseases *) are associated with a higher risk of mortality. (...) A higher BMI is observed more frequently in critical patients and non-survivors," says the study below directed by YD Peng.
This is how the body mass index is calculated
You can calculate your body mass index by dividing (dividing) your body weight in kilograms by your height in meters by two. With a weight of 60 kilograms and a height of 1.60 meters, this would result in a BMI of 23.4. A BMI of 18 to 25 stands for normal weight , with a value over 25, doctors speak of overweight and a BMI of over 30 speaks for obesity (obesity).
