Conclusions: Women with low BMI are at increased risk of osteoporosis. The change in risk associated with a 1 unit change in BMI ( approximately 5-8 lb) is of greater magnitude than most other modifiable risk factors. To help reduce the risk of osteoporosis, patients should be advised to maintain a normal weight.
Does BMI affect bone density?
Body weight is directly associated with bone mineral density (BMD). A low body mass index (BMI) has been identified as an important risk factor for lower BMD and predicts greater bone loss in older age (118, 138) and in younger persons in the absence of menses and/or an eating disorder (113).
Can low body fat cause osteoporosis?
It is well established that low body mass is correlated with reduced BMD and an increased risk of osteoporosis. However, controversial studies have indicated that increased percentage body fat (PBF) and abdominal fat accumulation are strongly associated with low BMD[5, 6].
What BMI is osteoporosis?
Men with a BMI of 23.0 to 24.9 kg/m2 harbored about a 30% lower osteoporosis risk than and a similar diabetes risk to those with a BMI of 21.0 to 22.9 kg/m2.
Who is less likely to get osteoporosis?
Women typically have smaller and lighter bones than men. As a result, women develop osteoporosis far more often than men. Osteoporosis usually does not have a noticeable effect on people until they are 60 or older.
Why is low BMI a risk factor for osteoporosis?
Low BMI increases fracture risk, possibly because low BMI is associated with low bone mineral density (BMD), less soft tissue, and muscle weakness; however, the relationship between high BMI and fracture risk is complex.
Why do skinny people get osteoporosis?
Bone structure and body weight.
Petite and thin women have a greater chance of developing osteoporosis. One reason is that they have less bone to lose than women with more body weight and larger frames. Similarly, small-boned, thin men are at greater risk than men with larger frames and more body weight.
Do Skinny people get osteoporosis?
Thin people and those with small frames are more likely to develop osteoporosis. But being overweight puts women at risk for other serious medical conditions, including type 2 diabetes, high blood pressure, and coronary artery disease (CAD).
How does being underweight cause osteoporosis?
A lifelong lack of calcium plays a role in the development of osteoporosis. Low calcium intake contributes to diminished bone density, early bone loss and an increased risk of fractures. Eating disorders. Severely restricting food intake and being underweight weakens bone in both men and women.
Does being underweight increase osteoporosis?
Low body weight may increase your risk for low bone mineral density (BMD) and osteoporosis.
What is low body mass?
If your BMI is less than 18.5, it falls within the underweight range. If your BMI is 18.5 to 24.9, it falls within the normal or Healthy Weight range. If your BMI is 25.0 to 29.9, it falls within the overweight range. If your BMI is 30.0 or higher, it falls within the obese range.
Does being overweight help osteoporosis?
If obesity is defined on the basis of body mass index or body weight, it appears to protect against bone loss and fractures. However, if obesity is based on the percentage of body fat, it may be a risk factor for osteoporosis.
What are the two medications that may cause osteoporosis after long term use?
The medications most commonly associated with osteoporosis include phenytoin, phenobarbital, carbamazepine, and primidone. These antiepileptic drugs (AEDs) are all potent inducers of CYP-450 isoenzymes.
