骨質密度 Bone Mass Density
Bone Mineral Density (BMD): An Indicator of Bone Health
*What is BMD?
Bone Mineral Density measures the density and strength of bones and is used to assess the risk of osteoporosis. BMD testing helps evaluate bone health and prevent fracture risks.
*Normal Range
-Normal: T-score ≥ -1.0
-Low Bone Mass (Osteopenia): T-score between -1.0 and -2.5
-Osteoporosis: T-score < -2.5
*Causes of Low BMD
-Aging:
Bone loss naturally occurs with age, especially in postmenopausal women.
-Poor Nutrition:
Insufficient calcium and vitamin D intake affects bone health.
-Hormonal Changes:
Declining estrogen after menopause in women and lower testosterone in men impact bone density.
-Lack of Exercise:
A sedentary lifestyle or insufficient weight-bearing activities reduces bone mass.
-Chronic Illnesses or Medications:
Conditions like diabetes, rheumatoid arthritis, or long-term steroid use can lower BMD.
*How to Maintain Bone Health?
-Adequate Calcium and Vitamin D Intake:
Ensure daily intake of these nutrients to strengthen bones.
-Regular Exercise:
Weight-bearing activities such as walking, dancing, or stair climbing help increase bone density.
-Avoid Smoking and Excessive Alcohol:
These habits can weaken bones and increase the risk of fractures.
-Routine BMD Testing:
Regular scans are essential for older adults or those with a family history of osteoporosis.
*Conclusion
BMD testing is vital for early detection of osteoporosis risks. By maintaining a balanced diet, engaging in regular exercise, and undergoing periodic BMD evaluations, you can effectively preserve bone health and minimize the risk of fractures.
