Prevalence of Vitamin D Deficiency in Patients with Minimal Trauma Fractures^[*]

Abstract

Objective

To analyze the serum 25-hidroxyvitamin D [25(OH)D] in patients with minimal trauma fractures, and to verify the profile of these patients and their main fractures.

Methods

Cross-sectional study in which blood samples were obtained from 40 patients with minimal trauma fracture to evaluate their 25(OH)D levels. Variables analyzed: fracture type; age; sex; Vitamin D supplementation; smoking habits; exercise; sunscreen use.

Results

A total of 29 (72.5%) patients presented with 25(OH)D deficiency, 10 (25%) had insufficiency, and only 1 (2.5%) had sufficient levels. The patients who used vitamin D supplementation had 25(OH)D levels (24.8 ± 12.75) that were significantly (p = 0.048) higher than those who did not use it. In addition, patients who practiced exercise 2 to 3 times a week obtained a medium concentration of 25(OH)D (22.5 ± 6.08 ng/mL) significantly (p = 0.042) higher compared with those who did not exercise (15.5 ± 7.25 ng/mL).

Conclusion

The prevalence of vitamin D deficiency was 72.5%; those patients who exercised 2 to 3 times a week and those who used vitamin D supplementation had higher levels of vitamin D.
