From the Guidelines
A DEXA scan may be necessary for a 30-year-old with specific risk factors for premature bone loss, as identified in the most recent guidelines. According to the American College of Radiology's 2022 update on osteoporosis and bone mineral density 1, DXA may be used in patients under 65 years of age to evaluate bone mass density if there are additional risk factors. These risk factors may include:
- Long-term corticosteroid use (like prednisone)
- Certain medical conditions (hyperparathyroidism, celiac disease, inflammatory bowel disease)
- A history of fragility fractures
- Medications that affect bone density like some anti-seizure drugs or aromatase inhibitors
- Early menopause or prolonged amenorrhea in women
- Hypogonadism in men
- A strong family history of osteoporosis The scan is a low-dose X-ray that measures bone mineral density and helps assess fracture risk. While most bone density screening begins at age 65 for women and 70 for men, these specific circumstances may justify earlier testing to identify and address bone health issues before significant bone loss occurs. It is essential to discuss individual risk factors with a healthcare provider to determine the need for a DEXA scan. The American College of Physicians also recommends that clinicians obtain DXA for men who are at increased risk for osteoporosis and are candidates for drug therapy 1. However, the most recent and highest quality study 1 takes precedence in guiding clinical decision-making.
From the Research
Indications for DEXA Scan
- A DEXA scan is typically considered for patients who have an increased risk of fracture based on clinical risk factors, such as increasing age and female gender 2.
- The diagnosis of osteoporosis can be confirmed by DEXA if the 10-year risk of major osteoporotic fracture is > 10% 2.
- In younger individuals, where bone mineral density (BMD) is likely to be higher, DEXA is useful in determining if bone protective treatment is needed immediately or if it could be delayed until the T score falls below -1.5 2.
Specific Considerations for a 30-year-old
- There is no specific evidence to suggest that a 30-year-old would necessarily require a DEXA scan, unless they have specific risk factors for osteoporosis, such as long-term corticosteroid therapy, chronic inflammatory disease, malabsorption, or untreated premature menopause 2.
- The decision to perform a DEXA scan would depend on the individual's clinical risk factors and medical history.
General Guidelines for DEXA Scans
- DEXA scans are generally indicated for postmenopausal women with a high risk of fracture 3.
- The scan can help estimate fracture risk and identify those who may benefit from treatment.
- However, the guidelines for DEXA scans may vary depending on the individual's age, gender, and medical history.
