Lower mortality: Moderately overweight people live around 4 years longer

Lower mortality: Moderately overweight people live around 4 years longer

Fat people today have a lower mortality rate than normal people
Numerous scientific studies have shown that obesity and obesity are unhealthy. Nevertheless, a new study from Denmark shows that fat people today live longer than slim people. The researchers evaluated data from over 100,000 citizens.

Being fat is unhealthy
Research has shown that obesity costs many years of life. If you weigh too much, you have a higher risk of secondary or concomitant diseases such as diabetes, high blood pressure, arteriosclerosis (hardening of the arteries), fat metabolism disorders, coronary heart diseases such as heart attacks and certain cancers. Three out of four sufferers develop such secondary diseases. On the other hand, a recent study showed that overweight people don't necessarily live healthier. The Body Mass Index (BMI) says little about our health, according to scientists at the University of California in Los Angeles (USA). And Swedish researchers are now reporting that fat people today live even longer than slim people.

Obese people have a lower mortality rate than slim ones
According to a new study, obese people today have a lower mortality rate than normal people. According to study author Børge G. Nordestgaard from the Copenhagen University Hospital, the reason for this change has not been clearly clarified. Data from more than 100,000 people in Denmark were evaluated for the study published in the Journal of American Medical Association (JAMA). These were examined for their mortality in the years 1976 to 1978, 1991 to 1994 and from 2003 to 2013. Various health risks such as tobacco consumption were taken into account.

Optimal BMI increased over the years
The normal weight is determined on the basis of the body mass index (BMI). From a BMI of 30, one speaks of obesity. That would be 86.5 kilograms for a body height of 1.70 meters. The BMI can be calculated by dividing the body weight in kilograms by the square of the height in meters. With a BMI between 25 and 30, a person is considered overweight and over 30 as obese. The current study showed that people with a BMI of 23.7 (that is, a weight of 78 kg and a size of 1.83) lived the longest in the 1970s. At the beginning of the 1990s, the optimal BMI was 24.6 - that is five kilos more for the same height. And in the span from 2003 to 2013, the optimal BMI even increased to 27, which corresponds to a good 90 kilograms with a height of 1.83 - twelve kilograms more than in the 1970s.

Rethink definition of overweight
The study also revealed that obese people had a higher mortality rate than normal weight people in the 1970s, but have lived just as long since the 2000s. According to the researchers, the findings must redefine where overweight begins. According to a report from the ScienceDaily website, Nordestgaard said: "If this finding is confirmed in other studies, it would indicate that WHO needs to revise its current definitions of overweight, based on data from before the 1990s . ”The scientist also indicated that further investigation is necessary to understand the reason for this change and its effects. The researchers also wrote that the results should not be interpreted as meaning that people no longer pay attention to healthy eating. US and Canadian scientists came to similar results years ago as their Swedish colleagues. At the time, they also reported in the Journal of the Medical American Association (JAMA) that overweight people live longer, according to a meta study. However, the mortality risk associated with extreme obesity increases enormously. (ad)
