For women, when is screening for osteoporosis indicated?

Screening for osteoporosis in women is particularly important because of the increased risk of fractures as they age, especially post-menopause due to the decline in estrogen levels, which is protective against bone loss. The recommendation to begin screening for osteoporosis at age 65 is based on evidence that a significant number of women in this age group experience declines in bone density that could lead to osteoporosis.

However, women who have specific risk factors for osteoporosis—such as a family history of osteoporosis, a personal history of fractures, long-term use of corticosteroids, low body weight, smoking, or specific medical conditions—should be screened earlier than age 65. This proactive approach helps to identify individuals at higher risk of fractures so that appropriate preventive measures, such as lifestyle changes or medication, can be implemented timely.

Thus, the recommendation aligns with clinical guidelines, recognizing both the general population's age-related risk and the impact of individual risk factors on the likelihood of developing osteoporosis.
