Global vitamin D map reveals major health issue

Global vitamin D map reveals major health issue
DSM, which contributed to developing the data and map, supports IOF’s call to address vitamin D insufficiency as a priority public policy issue and emphasize the role of supplementation in addressing this problem.

The International Osteoporosis Foundation (IOF) launched an interactive global map of vitamin D status, which presents a snapshot of vitamin D levels worldwide. The map and accompanying publication confirm that vitamin D insufficiency is a major public health issue in both the developing and industrialized world, with more than one-third of all the populations studied, showing insufficient levels of vitamin D.

DSM, which contributed to developing the data and the map, strongly supports IOF’s call for health care decision makers to take immediate action to address vitamin D insufficiency as a priority public policy issue, and emphasize the role of supplementation as a key tool for addressing this problem.

Key findings include:

· Overall, insufficient vitamin D levels were detected in more than one third of the study population[3]

· Vitamin D insufficiency affects both the developing world and industrialized world

· The main source of vitamin D is sunlight, but even in sunny countries, vitamin D levels are generally low and below recommended levels (taking India as example: a sunny country; yet, with low vitamin D status)

· Rates of vitamin D insufficiency are higher amongst women than men

· It is estimated that 50 percent to 70 percent of the European adult population have insufficient levels of vitamin D

· In U.S. adults, vitamin D insufficiency estimates range from 20 percent (non-Hispanic whites) to 70 percent (non-Hispanic blacks).

· Older people are especially at risk for vitamin D insufficiency, including older women who are a risk group for osteoporosis, and those living indoors in institutionalized care.

Osteoporosis is a serious chronic disease which affects hundreds of millions of people worldwide. Vitamin D improves bone mineral density, which lowers risk of fracture, whilst also improving muscle strength, balance, and leg function which decreases the risk of falling and sustaining a fracture in the first place. As a consequence, vitamin D insufficiency has been linked to a higher risk of osteoporotic fractures.

Studies show that adequate vitamin D can reduce the risk of falls and fractures by around 30 percent. In Germany, research indicated that regular vitamin D supplements can help achieve healthcare cost savings of between Euro 585-778 million in one country alone.

Judy Stenmark, CEO of the International Osteoporosis Foundation commented: “IOF urges people at risk of osteoporosis and generally all seniors aged 60 years and older to ensure optimal levels of vitamin D. In these high risk groups IOF recommends 800 to 1,000 IU per day supplementation for fall and fracture prevention. With the launch of these maps, we are calling on health professionals to be aware of the status of vitamin D insufficiency within their own country and urge them to take simple and inexpensive steps to correct it. This will ultimately improve, and even save, lives.”

Prof. Heike Bischoff-Ferrari, DrPH, Director Centre on Aging and Mobility, University of Zurich added: “The reality is that natural production of vitamin D through sunlight decreases with age, and it is very difficult to achieve sufficient vitamin D through diet alone, especially in the senior population. The good news is that vitamin D supplementation offers an effective, inexpensive, and safe public health strategy that can make a significant difference to people’s health and quality of life, by reducing 30 percent of falls and hip fracture.”

Dr. Manfred Eggersdorfer, Senior Vice President Nutrition Science & Advocacy DSM, commented: “The maps are a major advance in the fight against vitamin D deficiency. We know that vitamin D deficiency is linked to serious diseases such as rickets in children and osteoporosis in the elderly, but our understanding of the scale and extent of the problem was far too limited. We now have a much better understanding of the picture of vitamin D insufficiency, and confirmation of its importance as a global public health issue.

The map has also created a very clear picture as to where the vitamin D insufficiency knowledge gaps exist and where further research is required. Dr. Eggersdorfer added, “There is far too little data available, for example, in relation to adolescents and young people, and across the developing world in general. These maps are an important starting point, but it is essential that research continues to better understand the scale of vitamin D insufficiency.”

DSM joins IOF in calling on healthcare policymakers to raise awareness of vitamin D insufficiency and to take action to ensure intake of recommended vitamin D levels, including through safe and effective measures such as food fortification, access to proper supplements and better consumer education.
