Extra weight saves from death


Experts from the University of Copenhagen, said that people with excess weight, contrary to popular belief, are more likely to live longer than those whose weight is considered normal. A study conducted by researchers, showed that the lowest risk of early death from various causes can boast of men whose body mass index is significantly above the accepted norm.

The body mass index — the ratio of the mass of the human body in kilograms divided by the square of his height in meters. The norm is the index of 18.5 to 24.99. Some believe this lack of universal criteria — in particular, it is not readily available to athletes, high weight due to muscle mass instead of fatty tissues. However, in various studies, the body mass index as an indicator for comparison is used very actively.

The new study was conducted in three phases, and in total it was attended by about 120 thousand people, information about the body mass index which was known. As it turned out, in the XXI century the mass index, in which the risk of death from various causes has been minimal, was about 27. This figure is classified as “normal”. They also found that the mortality risk of people with obesity of the first degree recently caught up with the risk at normal weight.

It is curious that, according to the authors of the study, three decades ago “optimal” body mass index to longevity was indeed within the so-called normal weight and was about 23,7, however for some reason over time it has increased.

Their work, the scientists published in the scientific Journal Journal of the American Medical Association.

This is not the only recent study, which the authors come to the conclusion that perceptions of “healthy” body mass index, probably, require some revision. In January in the journal Obesity published an article, authors of which for 13 years was observed for 400 thousands of people who at the beginning of the study were 50 to 71 years. The results of this study, stated that “optimal” for the longevity of the body mass index is 26.

By the way, this year obese for the first time became more than people with the lack of weight.
