Obesity, particularly visceral fat, increases fracture risk, challenging previous beliefs. This risk is amplified in older adults due to age-related changes and obesity-induced factors, necessitating further research into treatments.
Area of Science:
- Gerontology
- Metabolic Disorders
- Orthopedics
Background:
- Obesity was previously thought to protect against fractures, but recent evidence suggests an increased risk, especially with higher visceral adipose tissue.
- In older adults, obesity exacerbates age-related fat redistribution, sarcopenia, and reduced mobility, increasing fall and fracture susceptibility.
- Chronic inflammation, altered adipokines, vitamin D deficiency, and insulin resistance contribute to elevated fracture risk in obese older individuals.
Purpose of the Study:
- To review the current scientific evidence on the increased risk of fractures in patients with obesity.
- To explore the specific factors contributing to this risk, particularly in older adults.
- To discuss the implications for diagnosis, risk assessment, and potential interventions.
Main Methods:
- Literature review of recent scientific evidence.
- Analysis of the interplay between obesity, visceral adipose tissue, and fracture risk.
- Examination of age-related changes and comorbidities influencing fracture susceptibility.
Main Results:
- Obesity, especially visceral adipose tissue accumulation, is linked to a higher fracture risk, contradicting earlier assumptions.
- In older individuals, obesity intensifies age-related changes, increasing the risk of falls and fractures.
- Diagnostic tools and risk scales may be less accurate in obese patients, potentially underestimating their fracture risk.
Conclusions:
- The paradigm shift indicates obesity is a risk factor for fractures, particularly in older adults.
- Factors like inflammation, sarcopenia, and metabolic dysfunction in obese individuals heighten fracture risk.
- Weight loss interventions and further research on anti-osteoporotic treatments in obese populations are warranted.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
Role of Vitamins in Maintaining Bone Health
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...
Essential Minerals for Bone Health
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...

Hormones and Bone Tissue
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
