By Amy Norton NEW YORK (Reuters Health) - Older men and women with vitamin D deficiency are more likely to fall multiple times in the course of a year than their peers with adequate vitamin D levels, researchers in The Netherlands have found. Vitamin D may be best known for its role, along with calcium, in maintaining bone health. However, vitamin D is also important for muscle mass and strength, and compromised muscle function may explain the fall risk seen in this study, according to the...

By Megan Rauscher NEW YORK (Reuters Health) - In a study of healthy adolescent girls, researchers found that insufficient vitamin D levels were a relatively common finding, with non-white girls more severely affected. According to the UK-based study team, "reduced sunshine exposure rather than diet explained the difference in vitamin D status of white and non-white girls" in the study, reported in the Archives of Disease in Childhood. "Vitamin D deficiency during childhood and...

By Amy Norton NEW YORK - Pregnant women with relatively low amounts of vitamin D in their diets tend to give birth to smaller infants, a new study suggests. Canadian researchers found that pregnant women who drank little milk or had a lower vitamin D intake tended to have smaller babies than women with higher intakes. Fortified milk is a primary source of vitamin D in Western diets, and the nutrient may be the main reason why women's milk consumption was linked to birthweight, according to...

NEW YORK (Reuters Health) - Study findings support an association between low blood levels of vitamin K and an increased prevalence of hand and knee osteoarthritis -- the most common form of arthritis, occurring mainly at older ages, in which the cartilage cushioning the joints breaks down over time, leading to pain, stiffness and, often, limited mobility. "We are not yet sure if vitamin K is in fact the cause of osteoarthritis," lead author Tuhina Neogi, from Boston University, told...

NEW YORK (Reuters Health) - The long-term use of warfarin, a drug commonly prescribed to reduce the risk of blood clots, appears to increase the risk of fractures associated with osteoporosis, a bone-thinning condition that usually increased with age, according to a report. As the study authors note, warfarin prevents coagulation by blocking vitamin K, which is needed to activate certain clotting factors. Because vitamin K is also used to activate proteins involved in bone formation,...

NEW YORK -- The recommended daily intake for vitamin B-12 should be more than doubled from the current level, researchers argue in a new report. In a study of 98 middle-aged and older women, the researchers found that 6 micrograms of B-12 per day seemed to be enough to prevent signs of mild B-12 deficiency. That compares with the current recommended dietary allowance (RDA) of 2.4 micrograms per day. The findings, along with those from several past studies, "strongly suggest" that the RDA...

By Susan Heavey WASHINGTON -- Higher amounts of vitamin D could help make it easier to breathe, according to new findings released on Monday, offering possible good news for smokers, asthmatics and other people with respiratory problems. Researchers at the University of Auckland in New Zealand found people with higher levels of the vitamin in their systems showed better lung function than those with lower amounts. While the vitamin, which people get mostly from sunlight, is linked to lung...

NEW YORK (Reuters Health) - Taking vitamin D supplements may reduce the risk of falls in elderly people in residential care facilities, results of a study published in the Journal of the American Geriatrics Society suggest. In the study, Australian researchers examined the effect of vitamin D supplementation in 625 residents of 149 residential care facilities. The subjects were not vitamin D deficient. The participants were randomly assigned to receive vitamin D supplements or...

By Matias A. Loewy BUENOS AIRES (Reuters Health) - In all regions of the world, more than half of postmenopausal women with the crippling bone disease osteoporosis are vitamin D deficient, regardless of age, latitude or season, researchers from US, the Netherlands and UK said here last week at the 11th World Congress on the Menopause. According to the investigators, "These results underscore the need to improve physician and patient awareness of the importance of adequate vitamin D...

LONDON (Agence de Presse Medicale) - Vitamin D deficiency is nearly universal in cases of hip fractures, researchers in Scotland reported online in Current Medical Research and Opinion on Monday. A look-back study of 548 patients older than 60 years of age who were admitted at South Glasgow University Hospital in the previous 4 years, showed that 97.8 percent of the patients had vitamin D levels below normal. In 25 percent of the cases, levels were so low as to be described as "effectively...
