Inadequate vitamin D recommendations

October 12, 2011

Is the Institute of Medicine report on calcium and vitamin D good science?

From Biological Research for Nursing

This editorial reveals that recommended vitamin D intakes and target blood levels were set too low in the November 30, 2010, Institute of Medicine (IOM) report of the National Academies “Dietary Reference Intakes for Calcium and Vitamin D”.

The author found that the criteria stipulated by the Federal sponsoring agencies for the IOM committee’s selection of studies to review in formulating their new recommendations were inadequate. They included randomized controlled trials and prospective observational studies but not ecological studies, case-control studies with vitamin D status at diagnosis or studies considering exposure to the main source of vitamin D in humans, sunlight.

The IOM’s report states that the only health benefit of vitamin D is for bone health. It recommends that those aged 1–70 years take 600 IU of vitamin D each day (800 IU for those over 71. This paper however argues that there are many non-bone-related health benefits associated with a higher intake (or a higher production) of vitamin D, such as reduced risks of contracting—or dying from—colon, prostate and breast cancer, non-Hodgkin lymphoma, cardiovascular disease, autoimmune diseases, diabetes mellitus types 1 and 2, neurological disorders, several bacterial and viral infections, and adverse pregnancy outcomes. Over 30 vitamin D experts and 9 organizations agree with this position and believe that vitamin D has many more health benefits than just for bones, and that recommended daily reference intake levels will continue to rise.

Antepartum Bed Rest for Pregnancy Complications: Efficacy and Safety for Preventing Preterm Birth

From Biological Research for Nursing 

This article reveals that bed rest may not be the best option for preventing preterm labor and may even cause harm to the mother and baby. Bed rest is prescribed for up to 1 million women in the U.S. annually to treat pregnancy complications, based on the assumptions that it is effective in preventing preterm birth and is safe for both the mother and baby. The researcher found a number of troubling issues with bed rest, including such concerns as fatigue, depression,  and loss of: muscle function, bone and weight. The author suggested that “nurses can challenge bed-rest treatment by functioning as advocates for women and educating them about the evidence for bed-rest treatment as well as the risks and benefits”. This article is part of a special issue on “Women’s health across the lifespan”.
