    Title: The prevalence of deficiency and insufficiency of vitamin D among adolescent athletes, during pre-participation evaluation. Introduction: Vitamin D is a hormone that acts on bone metabolism and calcium homeostasis, along with parathyroid hormone (PTH). In Brazil, we use the parameters defined by the Endocrine Society, which states: deficiency <20 ng/mL; insufficient - level of 20 ng / ml and 29 ng / ml; and sufficiency - level of 30 ng / ml and 100 ng / ml. Studies show a high prevalence of inadequate levels of vitamin D in the world, including Brazil. Objective: To evaluate the prevalence of vitamin D deficiency and insufficiency of adolescent athletes during pre-participation evaluation and compare levels of vitamin D extracting the results according to gender, mode and place of training. Methodology: A retrospective study by analyzing the records of athletes from 10 to 19 members of staff of the ten modes. The tabulation of the data was done in a spreadsheet (Excel template) and statistical analysis using SPSS software. Results: from the 166 analyzed records, 99 (59.6%) were female and 67 (40.4%) were male. Ninety-seven athletes (58.4%) had vitamin D levels out of the reference range, being 44.6% with insufficient levels and 13.8% lacking vitamin D. There was no statistically significant association between gender and classification of the results (p = 0.464). However, there was a statistically significant association between training location and classification of the results (p = 0.003): the group of athletes practicing indoor training showed higher proportion of vitamin D insufficiency than the group practicing outdoor training (50, 5% and 36.2% respectively), as well as deficiency (18.6% and 7.2% respectively). It was not possible to assess the association between type of sport and classification of results of vitamin D due to the low representation of some schemes. Conclusion: The study found a high prevalence of inadequate levels of vitamin D among adolescent athletes (10-19 years). Thus, we suggest including vitamin D level examination on laboratory tests of pre-participation evaluation. This will enable the correction of inadequate levels of this vitamin – which is essential for bone formation in this group age - and also the prevention of injury and other harmful effects to health and athletic performance of these athletes.
