A new study published in the British Journal of Nutrition analyzed 200 studies based on the correct presence of vitamin D in people from 44 different countries.

The highest values ​​of vitamin D are found in North America. The study's lead researcher , Dr. Kristina Hoffmann of the Mannheim Institute of Public Health ( MIPH ), Heidelberg said: " The strength of our study is that we used strict inclusion criteria to filter and compare data . Although we found a high degree of variability in relation to the presence of vitamin D in the body of people residing in different parts of the world , more than a third of the examined reported values ​​lower than 50 nmol / l of media."

Low levels of vitamin D have a potentially serious impact on health, especially the health of bones and muscles. In children, vitamin D deficiency is a cause of rickets , while in adults the low values ​​are associated with osteomalacia , osteopenia , osteoporosis and fracture risk . The lack of vitamin D could , according to some studies , also increase the risk of cancer and cardiovascular disease . Yet , despite its importance to health , the data about the state of vitamin D in the population are limited and studies are hampered by a lack of consensus and consistency.


Key findings of the study:

 37.3% of the studies reported values ​​of vitamin D less than 50 nmol / l, values ​​considered inadequate by the health authorities around the world .
Only a limited number of studies are available for Latin America .
The values ​​of vitamin D are higher in North America than in Europe or the Middle East.
Age-related differences were observed for the regions of the Middle East and the Asia- Pacific region, but not elsewhere .
The substantial heterogeneity between studies in different areas it impossible to draw conclusions about the overall state of the presence of vitamin D in the world.

Judy Stenmark , CEO of the International Osteoporosis Foundation (IOF ) has noted: " Given the ' overall increase in the number of elderly and the increase of nearly four times of fractures due to osteoporosis since 1990, the public health officials face the impact of inadequate vitamin D on overall health of the elderly , adolescents, children and adults , in short the entire population . IOF urges further research and consequent public health measures that can contribute to improving the state of vitamin D, especially groups of people at high risk . "
