The purpose of this descriptive study was to assess serum levels of 25(OH) vitamin D3 (25(OH)D) in participants who voluntarily participated in a fitness assessment and correlate this with muscular strength, weekly exercise, overall body composition, and dietary intake of vitamin D and calcium. Thirty-six participants were recruited. Anthropometric measurements and handgrip strength were taken with blood analyses completed utilizing 25-hydroxyvitamin D assay. A dietary screening survey was used to assess calcium and vitamin D intake. All data collection was completed at time of assessment appointment. Statistical analyses completed utilized Pearson's and Kendall's Tau correlation, with level of significance set at p < 0.05. Twenty-two percent of our sample were 25(OH)D deficient and 33% 25(OH)D insufficient, with 16% consuming adequate vitamin D and 5% consuming adequate calcium. Eight of the females and one male had below average DXA assessments for bone health. Vitamin D intake was significantly correlated with serum 25(OH)D levels (τ = 0.29, p<0.01). In females there was an inverse relationship between 25(OH)D and weight (r = -0.45, p<0.05). Thirty-one percent of participants had higher than desirable waist circumference and were 25(OH)D insufficient or deficient. This sample had a high rate of 25(OH)D insufficiency and deficiency, with most not consuming adequate amounts of calcium and vitamin D. Normalizing serum 25(OH)D through food and supplements has the potential to positively impact several parameters of an individual's health including weight status, visceral adiposity and waist circumference, and bone health.
本描述性研究的目的是评估自愿参加健身评估的参与者的血清 25(OH)维生素 D3(25(OH)D)水平，并将其与肌肉力量、每周运动、总体身体成分以及维生素 D 和钙的饮食摄入量相关联。共招募了 36 名参与者。使用 25-羟维生素 D 测定法完成血液分析，同时进行人体测量和握力测试。使用膳食筛选调查评估钙和维生素 D 的摄入量。所有数据收集均在评估预约时完成。完成的统计分析包括 Pearson 和 Kendall's Tau 相关性分析，显著性水平设为 p<0.05。我们的样本中有 22%的人维生素 D 缺乏，33%的人维生素 D 不足，16%的人摄入足够的维生素 D，5%的人摄入足够的钙。8 名女性和 1 名男性的 DXA 骨健康评估低于平均水平。维生素 D 的摄入量与血清 25(OH)D 水平呈显著正相关（τ=0.29，p<0.01）。在女性中，25(OH)D 与体重呈负相关（r=-0.45，p<0.05）。31%的参与者腰围大于理想值，且维生素 D 不足或缺乏。该样本中维生素 D 不足和缺乏的比例很高，大多数人没有摄入足够的钙和维生素 D。通过食物和补充剂使血清 25(OH)D 正常化可能会对个体健康的多个参数产生积极影响，包括体重状况、内脏脂肪和腰围以及骨骼健康。
