Vitamin D status has been associated with performance, health, and well-being in athletic populations. The measurement of vitamin D status via 25-hydroxyvitamin D [25(OH)D] testing has increased in the general population, as has vitamin D supplement use. It is unclear if similar patterns exist in collegiate athletics programs.
To describe the clinical care related to the prevention, evaluation, and treatment of vitamin D deficiency and insufficiency used by sports medicine providers with National Collegiate Athletic Association (NCAA) Division I programs.
Cross-sectional study.
Population-based online survey.
All NCAA Division I head athletic trainers.
MAIN OUTCOME MEASURE(S): Information related to 25(OH)D testing, vitamin D supplementation, vitamin D-related protocols and procedures, and characteristics of athletic programs and participants.
We received 249 responses (72% response rate). Use of 25(OH)D testing was described by 68% of participants, with the most common indicators being health status/history (78%) and injury status/history (74%). One-fifth of participants stated that vitamin D testing was conducted as screening (without a specific cause or indication). Target blood vitamin D concentrations were highly variable. A range of 8 to 1660 annual vitamin D blood tests was reported at a cost of <$50 (8%), $51 to $100 (51%), $101 to $150 (20%), and >$150 (10%). Forty-two percent of programs covered the cost of vitamin D supplements. More than half of the participants indicated that vitamin D blood testing and supplements were not a good use of program funds. In comparison with Football Championship Subdivision programs, Football Bowl Subdivision programs were more likely to conduct vitamin D testing and pay for vitamin D supplements, and their providers were more likely to believe that testing and supplements were a good use of program funds.
A great deal of variability was present in vitamin D-related clinical practices among NCAA Division I athletics programs, which reflects existing contradictions and uncertainty in research, recommendations, and guidelines. Knowledge of current practice patterns is important in evaluating and establishing best practices, policies, and procedures for sports medicine and sports nutrition professionals in the collegiate setting.
维生素 D 状态与运动员的表现、健康和幸福感有关。通过 25-羟维生素 D [25(OH)D] 检测来测量维生素 D 状态在普通人群中有所增加，维生素 D 补充剂的使用也有所增加。在大学生体育项目中，是否存在类似的模式尚不清楚。
描述与国家大学体育协会（NCAA）一级项目中运动医学提供者预防、评估和治疗维生素 D 缺乏和不足相关的临床护理。
横断面研究。
基于人群的在线调查。
所有 NCAA 一级头部运动训练师。
与 25(OH)D 检测、维生素 D 补充剂、维生素 D 相关方案和程序以及运动项目和参与者特征相关的信息。
我们收到了 249 份回复（72%的回复率）。68%的参与者描述了 25(OH)D 检测的使用，最常见的指标是健康状况/病史（78%）和受伤状况/病史（74%）。五分之一的参与者表示，维生素 D 检测是作为筛查进行的（没有具体的原因或指征）。目标血液维生素 D 浓度差异很大。报告的年度维生素 D 血液检测次数范围为 8 至 1660 次，费用低于 50 美元（8%）、51 至 100 美元（51%）、101 至 150 美元（20%）和超过 150 美元（10%）。42%的项目涵盖了维生素 D 补充剂的费用。超过一半的参与者表示，维生素 D 血液检测和补充剂不是项目资金的好用途。与足球锦标赛分区项目相比，足球碗分区项目更有可能进行维生素 D 检测和支付维生素 D 补充剂费用，其提供者更有可能认为检测和补充剂是项目资金的好用途。
在 NCAA 一级运动项目中，维生素 D 相关的临床实践存在很大差异，这反映了研究、建议和指南中存在的矛盾和不确定性。了解当前的实践模式对于评估和制定体育医学和运动营养专业人员在大学环境中的最佳实践、政策和程序非常重要。
