In which demographic is a DEXA scan recommended as a routine screening?

A DEXA scan, or dual-energy X-ray absorptiometry, is a crucial tool for assessing bone mineral density and is primarily used to screen for osteoporosis. The recommendation for routine screening has specific demographics based on age and sex, given that the risk of osteoporosis and related fractures increases with age, particularly in women after menopause due to the decline in estrogen levels.

Routine screening is generally recommended for women aged 65 and older. This is based on evidence that postmenopausal women face a significantly higher risk of osteoporosis, making early detection and management essential for preventing fractures. While some guidelines may also recommend screening for younger women who have additional risk factors, the routine screening threshold clearly starts at age 65 for women.

In men, routine screening recommendations tend to be less aggressive, with many guidelines suggesting screening at age 70 and older, recognizing that they do have a lower, but still significant risk of osteoporosis and fractures.

Therefore, the most appropriate demographic for routine screening with a DEXA scan aligns with women aged 65 and older, reflecting the evidence-based recommendations for identifying individuals at greater risk for osteoporosis and related complications.
