December 15 2017. The December 2017 issue of Nutrients published the finding of German researchers of a significant presence of vitamin D deficiency in an older population.

The current study examined data from 1,079 participants, aged 65 to 93 years, in the Cooperative Health Research in the Region of Augsburg-Age (KORA-Age) study conducted in 2008/2009. The KORA Cooperative Health Research platform has evaluated the health of thousands of people living in the Augsburg area of Southern Germany for the past 30 years to understand the effects of environmental, lifestyle and genetic factors. “In this context, we were also interested in examining the micronutrient status of older adults, including vitamins” explained lead researcher Barbara Thorand of the Institute of Epidemiology, Helmholtz Zentrum München. “So far, in Germany, research data on this topic has been relatively thin on the ground.”

Blood samples collected in 2009 were analyzed for vitamins B12 and D, folic acid and iron. It was found half had suboptimal levels of vitamin D. “The results are very clear,” reported first author Romy Conzade. “Fifty-two percent of the examined older adults had vitamin D levels below 50 nmol/L [20 ng/mL] and thus had a suboptimal vitamin D status.”

In addition, 27.3% of the participants had suboptimal vitamin B12 levels, 11% had low levels of iron and 8.7% had inadequate folate levels.

“Our study also shows that regular intake of vitamin-containing supplements goes along with improved levels of the respective vitamins,” Dr Thorand noted.

“By means of blood analyses, the current study has confirmed the critical results of the last German National Nutrition Survey (NVS II), which revealed an insufficient intake of micronutrients from foods,” stated coauthor Annette Peters. “This is a highly relevant issue, particularly in light of our growing aging population.”

One thought on “High prevalence of deficiency among older individuals”

    Sun exposure is the best way to overcome vitamin D deficiency. It is also the most efficient manner to obtain vitamin D, producing up to 20,000 IU in 20 minutes of whole-body exposure. Sun exposure also produces many health benefits beyond stimulation of vitamin D production in the skin. Here are some facts:
    •A 20-year Swedish study shows that sun avoidance is as bad for the health as cigarette smoking.
    •A Spanish study shows that women who seek the sun have one-eleventh the hip-fracture risk as those who avoid sun.
    •Men who work outdoors have half the risk of melanoma as those who work indoors.
    •Women who avoid the sun have 10-times the risk of breast cancer as those who embrace the sun.
    •Women who sunbathe regularly have half the risk of death during a 20-year period compared to those who stay indoors.
    •Sun exposure increases nitric oxide production, which leads to a decrease in heart disease risk.
    •Sun exposure dramatically improves mood through the production of serotonin and endorphin.
    • Sun exposure increases the production of BDNF, which is vital to human health.
