- Abstract:
- Introduction: The prevalence of vitamin D deficiency is worldwide very high, but especially in the northern latitudes. Vitamin D deficiency causes diseases such as rickets, osteomalacia and osteoporosis. A connection between vitamin D deficiency or vitamin D insufficiency and various other diseases is currently being discussed and investigated. There is evidence that doctors and nurses are particularly vulnerable to have a low vitamin D status. Methods: In September 2009 venous blood samples were taken from employees of the Department of Internal Medicine and a control group at the University Hospital of Graz. The study participants were divided into following 3 groups: doctors, nurses and controls. Vitamin D levels of the employees and the control group were examined for significant differences. Additionally we acquired data concerning age, body weight, gender, holiday habits, calcium and vitamin D intake by food and UV-exposition during lunchtime by questioning and examining the test persons. Results: The total of 187 participants consisted of 53 doctors, 67 nurses and 67 individuals of the control group. In 144 (77 %) subjects we found normal vitamin D levels. Three individuals (2 %) showed deficient and 40 (21 %) insufficient Vitamin D levels, respectively. No test person had an elevated vitamin D level. The mean serum vitamin D level of all individuals was 40.7 ng / ml. A significant difference between mean serum vitamin D levels of doctors and other study groups could not be demonstrated. Discussion: In 23 percent of the individuals we detected low vitamin D levels. Taking into consideration that in September due to seasonal conditions vitamin D levels are at their highest, this seems to be a remarkably high percentage. Therefore, a future investigation must be expected to show even lower vitamin D levels in winter. A supplementation with at least 1000-2000 IU vitamin D3 per day should be recommended to individuals with deficient or insufficient vitamin D status to prevent detrimental effects on health aspects.
