It is commonly believed that overweight nothing but harm to the body cannot make. However, the Swedish researchers concluded that men with obesity are less likely to suffer rheumatoid arthritis.

A team of researchers from the Institute of malmö² in Sweden analyzed the effect of too much body weight on the condition of the joints, informs Netdoctor. Researchers concluded that men with high body mass index (BMI) less likely to suffer from rheumatoid arthritis. Interestingly, in regard of ladies this relationship was not found.

The study involved 50 705 subjects who also were participants in the 2 other major scientific works. As a result, it was revealed that boys with a BMI over 25 (overweight) and 30 (obesity) risk of development of rheumatoid arthritis in 40-63% lower than in people with normal weight.

Version researchers, unlike ladies, guys high BMI says more about the development of abdominal obesity or the presence of visceral fat. Apparently, it also protects them against the development of rheumatoid arthritis. "Abdominal fat produces certain types of signal molecules, which will likely also reduce inflammation in the joints," explained senior Manager of research Carl Turesson.

The body mass index is a value enabling to assess the degree of correlation between mass and growth, and thereby to indirectly estimate whether the weight is normal. BMI equals body weight in kg. divided by height in meters squared.
