Morbidly obese women are up to 40% more likely to injure their leg bones if they trip or fall over

Morbidly obese women are at an elevated threat of fracturing or breaking their leg bones if they trip and fall over, analysis introduced at an weight problems convention suggests.

Scientists on the Quebec Research Centre, in Canada, carried out a large examine the place they discovered that women with essentially the most extreme circumstances of weight problems had been bout 40 % more likely to harm a leg bone in the course of the examine than these of a wholesome measurement, the most important threat of any group.

Dr Anne-Frederique Turcotte, an epidemiologist who led the examine, advised it might be as a result of bigger women had more ‘issue stabilizing’, leaving them at larger threat of falling over. She added that fats additionally releases a compound that weakens bones.

The similar sample was not seen in males who participated within the examine, with those that had been underweight dealing with a two-fold larger threat of fracturing their arms — the very best of any group.

The scientists didn’t say why this was the case, though it might be down to the design of the examine. Previous analysis has advised obese males are additionally more likely to fracture their bones than these of a wholesome weight.

Obesity has lengthy been considered serving to to shield the bones towards harm from journeys and falls.

But a rising physique of analysis is popping the tables on this concept, suggesting that being obese or obese might really elevate an individual’s threat of damage.

About two in 5 Americans — or 138 million individuals — are obese, estimates from the Centers for Disease Control and Prevention recommend.


Body mass index (BMI) is a measure of physique fats primarily based in your weight in relation to your peak. 

Standard Formula:

  • BMI = (weight in kilos / (peak in inches x peak in inches)) x 703

Metric Formula:

  • BMI = (weight in kilograms / (peak in meters x peak in meters))


  • Under 18.5: Underweight
  • 18.5 – 24.9: Healthy
  • 25 – 29.9: Overweight
  • 30 or larger: Obese 

Researchers gathered information from more than 20,000 males and women aged 40 to 70 years outdated for about six years. 

All individuals lived in Quebec, Canada, and had been monitored between 2009 and 2016.

Each had their Body Mass Index (BMI) calculated to decide whether or not they had been morbidly obese, obese, obese, of a wholesome weight or underweight. 

A complete of 820 accidents had been recorded in the course of the examine interval, with 497 in women and 323 in males.

For women, the most typical had been main osteoporotic fractures — harm to the hip, backbone, wrist or leg — with 260 accidents recorded.

Leg fractures had been second commonest (219), adopted by arm fractures (141).

It was the identical amongst males with osteoporotic components the most typical, with 155 circumstances, adopted by leg fractures with 134 circumstances and arm fractures with 62 circumstances.

The paper was introduced on the European Congress on Obesity held in Maastricht, the Netherlands, final week.

It didn’t break down the figures to present what number of examine individuals had been obese, or the proportion which suffered fractures or accidents.

But outcomes advised the women that weighed essentially the most had been most liable to struggling a leg damage.

For comparability, those that had been obese had been 5 % more likely to injure their bone whereas those that had been underweight had a 5 % decrease threat, in contrast to somebody of common weight.

The scientists additionally discovered that for each two-inch rise in waist circumference the danger of a leg fracture ticked up by seven % in each age teams, whereas the danger of any fracture rose by three %. 

Turcotte mentioned: ‘Waist circumference was more strongly related to fractures in women than BMI. 

‘This could also be due to visceral fats — fats that may be very metabolically energetic and saved deep inside the stomach, wrapped across the organs — secreting compounds that adversely have an effect on bone power.

‘We additionally know that folks with weight problems take longer to stabilize their physique, when they trip, for instance.

‘This is especially pronounced when weight is concentrated on the entrance of the physique, suggesting that people with distribution of physique fats within the belly space could also be at larger threat of falling.’

This examine didn’t present that the fattest males confronted the identical threat as the most important women, which the scientists didn’t clarify.

But previous research has concluded that males with the next proportion of physique reality face the same threat of a fracture, or might even face the next threat.

One paper printed in February within the journal Endocrinology discovered that fatter males have a decrease bone density, which might go away them more likely to fracture a bone.
