Vitamin B-12 levels linked to bone loss in aging women

04.03.2004


Research suggests that Vitamin supplements may slow bone loss



Older women with low levels of vitamin B-12 are more likely to experience rapid bone loss, according to new research published this month in The Journal of Clinical Endocrinology & Metabolism. The new findings help to establish the importance of vitamin B-12 in the bone health of women as they age.

Vitamin B-12, which is found in animal products, such as meat, shellfish, milk, cheese and eggs, is needed to produce red blood cells and maintain a healthy nervous system. Still, little is known about the vitamin’s affects on skeletal health, specifically among aging women. Researchers at the University of California, San Francisco, led by Dr. Katie Stone, studied whether elderly women with low levels of vitamin B-12 suffer from more rapid bone loss.


Through a random, cohort study of 83 women over the age of 64 who participated in the Study of Osteoporotic Fractures, researchers archived baseline serum samples and measured hip bone mineral density in study subjects during two and six year follow-up examinations. Test results demonstrated that after adjusting for age, weight and clinic site, women with the lowest levels of B-12 (below 280 pg/ml) experienced significantly more rapid hip bone loss than women with higher levels of B-12 (above 280 pg/ml).

"While deficiencies in vitamin B-12 are uncommon among younger women, many older women suffer from vitamin B-12 deficiency," explains Dr. Stone. "Our research shows that the women with the lowest levels of vitamin B-12 are at an increased risk for bone loss in their hips, which could lead to fractures. We knew that vitamin B-12 benefited the nervous system, but our findings suggest that it may also benefit bone health." The authors note that these results indicate that for some elderly women, simple dietary supplements of vitamin B-12 or multivitamins or dietary modification may slow the rates of bone loss.

"A larger, randomized trial would be needed to determine whether treatment with supplemental vitamin B-12 could reduce rates of bone loss in elderly women," notes Dr. Steve Cummings, one of the investigators on the study.


JCEM is one of four journals published by The Endocrine Society. Founded in 1916, The Endocrine Society is the world’s oldest, largest, and most active organization devoted to research on hormones, and the clinical practice of endocrinology. Endocrinologists are specially trained doctors who diagnose, treat and conduct basic and clinical research on complex hormonal disorders such as diabetes, thyroid disease, osteoporosis, obesity, hypertension, cholesterol and reproductive disorders. Today, The Endocrine Society’s membership consists of over 11,000 scientists, physicians, educators, nurses and students, in more than 80 countries. Together, these members represent all basic, applied, and clinical interests in endocrinology. The Endocrine Society is based in Chevy Chase, Maryland.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
