Summary

<p>Background: Vitamin D has protective effect on</p><p>fractures and improves muscle strength. Cross sectional</p><p>studies have shown that low serum concentration of 25</p><p>hydroxy vitamin D[25 (OH) D] is related to decreased</p><p>muscle strength, balance disorders and increased risk of</p><p>falls. The purpose of this study was to assess the</p><p>correlation between serum 25 (OH) D concentrations,</p><p>grip strength and balance in older population to determine</p><p>if grip strength could be used in clinical practice to</p><p>estimate the risk of falls and muscle weakness</p><p>secondary to vitamin D insufficiency.</p><p>Materials and Methods: Fifty three participants over</p><p>65 years of age were enrolled. Demographics and</p><p>laboratory results including serum calcium, phosphorous,</p><p>alkaline phosphatase, 25 (OH) vitamin D and parathyroid</p><p>hormone concentrations were assessed. Hand grip</p><p>strength was measured by a hand dynamometer. Berg</p><p>balance scale was used for the assessment of balance.</p><p>Results: Grip strength and total score of Berg balance</p><p>scale of participants with 25 (OH) vitamin D levels &lt;20</p><p>ng/mL versus ?20ng/mL were compared. Berg balance</p><p>scale scores of patients with 25 (OH) D&lt;20 ng/mL were</p><p>higher than the other group (r:0.627, p=0.000).</p><p>Participants with 25 (OH) D vitamin level of ?20 ng/mL</p><p>had higher grip strength compared to the other group</p><p>(p=0.023 and p=0.037 for dominant and non-dominant</p><p>hand respectively).</p><p>Conclusions: Vitamin D is essential for muscle strength</p><p>and balance and therefore treatment of vitamin D</p><p>deficiency reduce the incidence of falls in older</p><p>population by improving muscle strength and balance.</p><p>Key Words: Vitamin D; geriatrics; Berg balance; muscle</p><p>strength</p>
