Osteoporosis prevention and the USPSTF (United States Preventive Services Task Force):
According to an article by Christopher Nordin, MD, the recommendation by the USPSTF (United States Preventive Services Task Force) to begin screening for osteoporosis at the age of 65 appears to neglect the fact that 25% of a women’s bone mass has already been lost by that time. He recommends that women have bone density screening at menopause so that lifestyle changes such as exercise, calcium, and vitamin D may be emphasized early. (6)
Calcium and bone mineral density loss:
How much bone mineral density loss can calcium supplements help prevent? Nordin, BE reviewed 32 major trials done on calcium supplementation for osteoporosis. According to the author, the trials generally supported calcium supplementation for the use of preventing about a 1 % bone density loss per year (1).
