The Women's Health Initiative results have led the Institute of Medicine (2010) to recommend which of the following guidelines related to hip fractures in women?
A)
All postmenopausal women should take 1200 mg of calcium per day to prevent osteoporosis.
B)
The standard daily recommended amount of vitamin D was increased to 400 IU/day.
C)
All adults should take 600 IU/day of vitamin D to maintain healthy bones.
D)
A combination of calcium and vitamin D does not appear to prevent hip fractures.
Ans:
C
Feedback:
The release of data from two clinical trials within the WHI (low-fat dietary patterns, calcium and vitamin D supplementation) has challenged conventional wisdom in other areas. The use of calcium (1000 mg/day) plus vitamin D (200 IU/day) was shown to result in a small but significant improvement in hip bone density but failed to reduce the risk of hip fractures. The IOM recommends that all adults should take 600 IU/day of vitamin D to maintain healthy bones.
