Vitamin D for older women

Older women with low levels of vitamin D, may be more likely to gain weight, a new study indicates.

Researchers from the Kaiser Permanente Center for Health Research in Portland, OR said their findings are significant since most women aged 65 and older do not have enough vitamin D in their blood.

The researchers followed more than 4,600 women aged 65 and older over the course of nearly five years. The study found the women with low levels of vitamin D gained about two more pounds during that time than those with normal levels of the vitamin.

Low levels of vitamin D were found in 78% of the women. These women generally weighed several pounds more to begin with. In the group of women that did gain weight, those with insufficient vitamin D levels gained 18.5 pounds over five years. In comparison, the women with normal vitamin D levels gained 16.4 pounds during that time frame.

The author said “Nearly 80% of women in our study had insufficient levels of vitamin D”. Older women may need higher doses of vitamin D to keep their bones strong and prevent fractures.
