Bone Mineral Density (BMD) testing, also known as bone density testing or osteoporosis screening, is primarily recommended for women aged 65 and older and men aged 70 and older, or for younger individuals who have specific risk factors for bone thinning or fractures. These tests are crucial for assessing bone strength and detecting osteoporosis early, allowing for timely intervention to prevent future fractures.
Understanding Bone Mineral Density (BMD) Testing
BMD testing uses a low-dose X-ray to measure the amount of calcium and other bone minerals in a segment of bone. The results help doctors determine your risk of osteoporosis and bone fractures. Detecting low bone density early can lead to lifestyle changes or treatments that significantly reduce the risk of serious complications like hip fractures. For more information on BMD, you can visit reputable health sites like the National Osteoporosis Foundation.
Recommended Ages for Women
For women, the general recommendation for a bone density test begins at a specific age:
- All women aged 65 and older should undergo bone density testing, regardless of their risk factors. This is a standard preventive health measure as bone density naturally decreases with age, and women are particularly susceptible to osteoporosis after menopause.
- Younger women at higher-than-normal risk for a fracture may need earlier screening. This includes women who:
- Have a history of a fragility fracture (a fracture from a fall from standing height or less).
- Are postmenopausal with certain risk factors.
- Have a low body weight (under 127 pounds).
- Are taking certain medications that can cause bone loss (e.g., corticosteroids, some anti-seizure drugs).
- Have a medical condition associated with bone loss (e.g., rheumatoid arthritis, celiac disease, hyperthyroidism).
- Have a family history of osteoporosis or hip fracture.
- Smoke or consume excessive alcohol.
Recommended Ages for Men
While osteoporosis is often associated with women, men are also at risk, especially as they age.
- Men are generally advised to discuss osteoporosis screening with their doctor if they're over age 70.
- Younger men at high risk for thinning bones should also consider earlier screening. Risk factors for men include:
- Taking medications that can lead to bone loss (e.g., some prostate cancer treatments, corticosteroids).
- Having medical conditions like hypogonadism (low testosterone), chronic kidney disease, or gastrointestinal diseases.
- A history of fragility fractures.
- Significant weight loss or being underweight.
- Smoking or excessive alcohol consumption.
- Family history of osteoporosis.
Key Recommendations at a Glance
Here’s a summary of the general recommendations for BMD testing:
| Group | General Recommendation Age | Considerations for Earlier Testing (High Risk) |
|---|---|---|
| Women | 65 and older | Younger women with higher-than-normal risk for a fracture |
| Men | 70 and older | Younger men at high risk for thinning bones |
Why Early Screening Matters
Early detection of low bone density allows for proactive management. This can involve lifestyle modifications, such as increasing calcium and vitamin D intake, incorporating weight-bearing exercises, and quitting smoking. In some cases, medication may be prescribed to slow bone loss or rebuild bone. Regular screening empowers individuals to work with their healthcare providers to maintain strong bones and enhance overall quality of life.

Consulting Your Doctor
It's important to have a conversation with your healthcare provider to determine the most appropriate time for you to undergo a bone density test. They can assess your individual risk factors, medical history, and lifestyle to provide personalized recommendations.
