Official Screening Guidelines for Women
For women, bone health recommendations often differ based on age and menopausal status. Medical organizations offer specific guidance to ensure timely detection of osteoporosis, a silent disease that progresses without symptoms until a fracture occurs.
Women 65 and Older
The U.S. Preventive Services Task Force (USPSTF), the Bone Health & Osteoporosis Foundation (BHOF), and other major medical groups recommend that all women aged 65 and older should undergo bone mineral density (BMD) testing. This is considered a universal guideline because osteoporosis risk significantly increases for all women in this age bracket, regardless of other risk factors.
Postmenopausal Women Under 65 with Risk Factors
Screening is also strongly recommended for postmenopausal women under age 65 who have one or more risk factors for osteoporosis. For these women, a clinical risk assessment tool can help determine if their fracture risk is equivalent to or greater than that of a 65-year-old woman without risk factors. Early screening can provide a critical baseline measurement and allow for proactive intervention.
Official Screening Guidelines for Men
While often associated with women's health, osteoporosis and low bone density affect millions of men. Recommendations for male screening have evolved, though some variation in guidelines still exists among organizations.
Men 70 and Older
Several prominent organizations, including the BHOF, recommend that men should be screened for bone density starting at age 70. This recommendation addresses the heightened risk of age-related bone loss that occurs in older males. Even though the prevalence is lower than in women, men have higher fracture-related mortality rates.
Men 50 to 69 with Risk Factors
Similar to younger women, men between the ages of 50 and 69 should be screened if they have risk factors. These factors can place a man at a significantly higher risk for developing osteoporosis and experiencing a fragility fracture. A doctor may use a clinical risk assessment tool to help determine the necessity of an earlier DEXA scan.
Understanding Key Risk Factors for Osteoporosis
Beyond age and gender, numerous factors can influence an individual's risk for osteoporosis, prompting the need for earlier bone density screenings. It is important to discuss these risk factors with your healthcare provider to create a personalized screening schedule.
Some common risk factors include:
- A parent who has broken a hip.
- Having a low body weight or small, thin frame.
- Lifestyle habits such as smoking or heavy alcohol consumption.
- Early menopause (before age 45).
- Long-term use of certain medications, including corticosteroids, some anti-seizure drugs, and proton pump inhibitors (PPIs).
- Medical conditions such as rheumatoid arthritis, celiac disease, or an overactive thyroid.
- Having a history of a bone fracture after age 50.
- Significant height loss over time.
What is a DEXA Scan and What Do the Results Mean?
A dual-energy X-ray absorptiometry (DEXA) scan is the most common and accurate method for measuring bone mineral density. It is a painless, non-invasive procedure that uses very low-dose radiation. The scan measures the density of your bones, typically in the spine and hip.
Results are reported as a T-score, which compares your bone density to that of a healthy young adult of the same sex.
- Normal bone density: A T-score of -1.0 or higher.
- Osteopenia: A T-score between -1.0 and -2.5. This indicates low bone mass and increased risk.
- Osteoporosis: A T-score of -2.5 or lower, indicating porous and brittle bones with a high risk of fracture.
Comparison of Screening Guidelines
| Organization | Women (General) | Women (with Risk Factors) | Men (General) | Men (with Risk Factors) |
|---|---|---|---|---|
| USPSTF | 65 and older | Postmenopausal under 65 (with risk factors) | Insufficient Evidence | N/A |
| BHOF | 65 and older | Menopausal with risk factors | 70 and older | 50-69 (with risk factors) |
| Mayo Clinic | 65 and older | Early (with risk factors) | 70 and older | Earlier (with risk factors) |
What if Your Test Shows Low Bone Density?
Receiving a diagnosis of osteopenia or osteoporosis is not a cause for panic. A bone density test is a powerful preventive tool, and an early diagnosis allows for effective management. Depending on the severity of the bone loss and your overall health, your doctor may recommend a combination of lifestyle changes and medication. Treatment options range from bisphosphonates to bone-forming medications. Lifestyle adjustments, including diet and exercise, are crucial components of any treatment plan.
Conclusion
The age recommendations for bone density screenings are a critical part of proactive healthcare for aging adults, particularly women over 65 and men over 70. However, these are not one-size-fits-all rules. For many, a variety of risk factors necessitate earlier testing. Speaking with a healthcare provider is the most effective way to determine the right screening schedule for your individual health profile.

Early detection and a personalized plan can significantly reduce the risk of fractures and improve quality of life as you age.
