Multivitamins don't prevent infections in older people
August 05, 2005Effect of multivitamin and multimineral supplements on morbidity from infections in older people (MAVIS trial): pragmatic, randomised double blind, placebo controlled trial BMJ Volume 331, pp 324-7
Multivitamin and mineral supplements don't appear to prevent infections in older people living at home, finds a study in this week's BMJ.
At least 10% of older people have a vitamin or mineral deficiency, which can lead to poor immunity and increased risk of infection. At least a quarter of older people in the UK take nutritional supplements, but it is unclear whether they have any influence on infections.
Researchers at Aberdeen University identified 910 men and women aged 65 or over who did not take vitamins or minerals. Participants were randomised to a daily multivitamin and multimineral supplement or a dummy (placebo) tablet for one year.
During this time, participants were asked to record contacts with primary care for infection, number of days with infection and quality of life. Numbers of antibiotic prescriptions and hospital admissions were also taken into account.
Supplementation did not seem to affect contacts with primary care, days with infection or overall quality of life. These results are consistent with several other studies on this issue.
Regular use of commonly available multivitamin and multimineral supplements is unlikely to reduce the number of self-reported infections or associated use of health services for people living at home, say the authors. It remains to be seen whether those at higher risk of infections, such as older people living in care, would benefit from supplementation.

Elevated inflammatory marker may be linked to increased risk of age-related eye disease
High blood levels of C-reactive protein, a substance linked to inflammation, appear to be associated with an increased risk for age-related macular degeneration.
Selenium Supplements May Increase the Risk of Type 2 Diabetes

Dietary vitamin B6, B12 and folate, may decrease pancreatic cancer risk among lean people

Multivitamins improve birth outcomes among children born to HIV-negative women
Each year an estimated 20 million children are born with low birth weight worldwide, more than 95% of them in developing countries. Low birth weight, defined as less than 2,500 grams (5.5 pounds), is associated with increased risk of negative health outcomes, including neonatal and infant mortality, poor growth and cognitive development, and morbidity due to chronic diseases later in life, such as diabetes and heart disease.
Vitamin D deficiency widespread during pregnancy
Even regular use of prenatal multivitamin supplements is not adequate to prevent vitamin D insufficiency, University of Pittsburgh researchers report in the current issue of the Journal of Nutrition, the publication of the American Society for Nutrition.
Vitamins: Science doesn't always match policy
Some one hundred years after the first vitamin was named, what is known about them has not translated into beneficial, standardized recommendations for public health, says Irwin Rosenberg, MD, University Professor, and director of the Nutrition and Neurocognition Laboratory at the Jean Mayer USDA Human Nutrition Research on Aging (USDA HNRCA) at Tufts University.
