Insights

Low bone mineral density (BMD) and osteoporosis are independent predictors of stroke and death. This study highlights a significant link between bone health and cardiovascular outcomes, warranting further investigation.

Area of Science:

  • Gerontology
  • Cardiovascular Medicine
  • Bone Metabolism

Background:

  • Emerging evidence suggests a link between atherosclerotic disease and osteoporosis.
  • Osteoporosis is a growing public health concern, particularly in aging populations.

Purpose of the Study:

  • To prospectively investigate the relationship between bone mineral density (BMD) and the risk of stroke and death.
  • To determine if decreased BMD is an independent predictor of adverse cardiovascular events.

Main Methods:

  • Bone mineral density (BMD) was measured in 4,302 individuals (mean age 59 years).
  • Participants were followed for a mean of 5.6 years, during which strokes and deaths were recorded.
  • Statistical analyses adjusted for age, sex, body mass index, smoking, hypertension, hyperlipidemia, and diabetes.

Main Results:

  • Decreased femoral neck BMD and osteoporosis were independent predictors of stroke.
  • The risk of death was significantly associated with lower femoral neck BMD and the presence of osteoporosis at baseline.
  • Hazard ratios indicated a substantially increased risk for stroke and death in individuals with lower BMD.

Conclusions:

  • Reduced bone mineral density, specifically at the femoral neck, and osteoporosis are independently associated with an increased risk of stroke.
  • These findings underscore a significant connection between bone health and cerebrovascular/mortality outcomes.
  • The identified relationship between osteoporosis and stroke/death merits further research due to its public health implications.

Bone Disorders01:29

Bone Disorders

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
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 Health01:25

Role of Vitamins in Maintaining Bone Health

The growth and maintenance of bone are regulated by a combination of nutritional factors, including vitamins, such as vitamin A, B12, C, D, and K.
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 Health01:31

Essential Minerals for Bone Health

The minerals contained in all of the food we consume are essential for our organ systems. However, certain essential minerals, such as calcium, phosphorus, magnesium, manganese, and fluoride, largely affect 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...
