Low vitamin D linked with CVD risk factors in teens - theheart.org - 0 views

    Palm Harbor, FL - In a large study of adolescents, low serum levels of 25-dihydroxyvitamin D (25[OH]D) strongly predicted prevalence of hypertension, hyperglycemia, and metabolic syndrome [1]. The findings were reported at the AHA 49th Annual Conference on Cardiovascular Disease Epidemiology and Prevention.

    Adolescents with vitamin-D levels in the lowest quartile were almost four times more likely to have metabolic syndrome than those with vitamin-D levels in the highest quartile. "I think that is quite alarming," lead author Dr Jared P Reis (Johns Hopkins Medical Institutions, Baltimore, MD) said in an AHA podcast issued to the media."

    It seems likely that low vitamin D levels are related to fatigue fractures, and that an increasing trend exists between TRACP-5b bone resorption marker elevation and fatigue fracture incidence. Though seldom detected by plain radiography, fatigue fractures often underlie unclear lower leg stress-related pain occurring in the distal parts of the tibia. Femoral neck fatigue fractures, when displaced, lead to long-term morbidity in a high percentage of patients, whereas, when non-displaced, they do not predispose patients to subsequent adverse complications. Importantly, an educational intervention can diminish the incidence of fracture displacement by enhancing awareness and providing instructions for earlier diagnosis of fatigue fractures

    Vitamin D is rare in food. Among the vitamin D-rich food, oily fish are considered to be one of the best sources. Therefore, we analyzed the vitamin D content in several commonly consumed oily and non-oily fish. The data showed that farmed salmon had a mean content of vitamin D that was ~25% of the mean content found in wild caught salmon from Alaska, and that vitamin D2 was found in farmed salmon, but not in wild caught salmon. The results provide useful global guidelines for obtaining sufficient vitamin D3 by cutaneous synthesis and from dietary intake to prevent vitamin D deficiency and its health consequences.ensuing illness, especially, bone fractures in the elderly.
