Toronto, INS. It may be surprising to know that the risk of fracture in women and men is associated with different reasons. This has been revealed at the European Congress on Obesity (ECO) held in the Netherlands. According to a research paper presented in this, obese and overweight women, especially if they have a large waist, have a higher risk of fracture than normal women. Whereas in the case of men, this risk increases not because of being overweight, but because of being underweight.
It has been previously believed that obese people have a lower risk of fractures. This is because the mechanical load on the bones is associated with increased body weight, which increases the mineral density (density of minerals) in the bones and is a determining factor in bone strength.
But the latest study suggests that obesity and the risk of bone fractures differ between men and women. To investigate this, researchers studied about 20 thousand people aged 40-70 years from Quebec (Canada). Body mass index (BMI) and waist measurement of participants were taken.
what was the result
The study’s median follow-up of 5.8 years found that 497 women and 323 men had fractures. There was a direct association of waist thickness with an increased risk of fracture in women. According to the analysis, every five centimeters (about two inches) of waist thickness increased the risk of fracture in any part of the body by three percent. Whereas in the lower part of the knee, this risk was seven percent higher. Not only this, ankle fractures were found to be more closely related to waist thickness. The special thing is that the risk of fracture was found to be higher in women with greater waist thickness than BMI.
Anne-Frédéric Turcotte, an expert in endocrinology and nephrology, says that this may be due to visceral fat. It is very active from the point of view of fat metabolism and as it accumulates in the stomach, it gets covered on other organs and secretes such compounds, which have a negative effect on the bones. In addition, a high BMI also increases the risk of fracture in women.
The risk of fracture increases by five percent when BMI increases from 25 kg/m2 to 27.5 kg/m2, while the risk increases to 40 percent when BMI is 40 kg/m2.
Until now, the risk of fracture in women was not known to be associated with obesity. It has only been said that it is normal for obese people to fall unbalanced, so they are more prone to fractures. Like the bones of the hip and thigh, the ankle is not protected by soft tissue, so it is more prone to fracture.
The study also found that men who had a BMI of less than 17.5 kg/m2 had almost twice the risk of fracture in the upper part of the knee compared to those with a BMI of 25 kg/m2. But the researchers say it remains to be seen whether this is an accurate result given the large number of fractures in men.
