en Vitamin D Status in Osteoporotic and Diabetic Patients and Athletic Healthy Individuals from Northern Greece بیوشیمی Biochemistry مقالات اصلی Original Article <div style="text-align: justify;">Background: Vitamin D deficiency is recognised as a pandemic in the developed world. However, the importance of prudent sun exposure tends to be overlooked, which is responsible for this pandemic. Methods: We investigated the vitamin D status in 326 adults, 165 females and 161 males: 99 Osteoporosis patients, 53 Type 1 Diabetes patients, 51 Type 2 Diabetes patients, and 123 Athletic Healthy individuals, from Northern Greece, through the measurement of total calcidiol in winter and summer by immunoenzymatic assay. Results: In the Whole Sample 23.31% had severe deficiency, 13.50% mild deficiency, 17.48% insufficiency, and 45.71% adequacy at the end of winter. Mean concentrations differed significantly (p <0.001) between males and females. The prevalence of deficiency in the young was significantly lower than in the middle-aged (p = 0.004) and in the elderly (p <0.001), while it was significantly lower (p = 0.014) in the middle-aged than in the elderly. The best vitamin D status was found in the Athletic Healthy individuals, followed by the Type 1 and Type 2 Diabetic patients, while Osteoporotic patients had the poorest status. The difference in mean concentrations between winter and summer was significant (p <0.001). Conclusions: Vitamin D status deteriorated with increasing age and it was better in males than in females. Our findings suggest that outdoor physical activity in a Mediterranean country can cover the vitamin D needs of the young and the middle-aged, but not of the elderly, without the need for dietary supplements.</div> Total calcidiol, osteoporosis, Type 1 diabetes, Type 2 diabetes, Vitamin D status. 565 576 http://rbmb.net/browse.php?a_code=A-10-1048-1&slc_lang=en&sid=1 Constantine Anetakis kanetakis@bmsc.ihu.gr . 100319475328460016781 100319475328460016781 Yes Laboratory of Clinical Chemistry, Faculty of Biomedical Sciences, School of Health Sciences, Alexandrian Campus of International Hellenic University, 57400 Sindos, Thessaloniki, Greece.
