Introduction
Serum hydroxyvitamin D [25(OH)D] has a role in several aspects of physical performance. Our aim was to determine the possible association between serum 25(OH)D deficiency on the fall risk in young adults by using an objective computerized technique.
Materials and methods
This cross-sectional study included 80 adults aged 18–40 years with 25(OH)D deficiency and 40 age-matched controls. The participants were devided into three groups according to serum 25(OH)D levels: Group 1; deficient, Group 2; insufficient and Group 3; sufficient (serum 25(OH)D level < 20, 20 to < 30 and 30–100 ng/mL, respectively). The age, gender, height and weight were recorded. To evaluate the fall risk, the Berg Balance test as a clinical assessment and a computerised posturography devise as an objective technique were used. Serum 25(OH)D levels were analyzed by ELISA. Pearson Chi-square, the Kruskal Wallis and Spearman correlation tests were used for statistical analysis.
Results
42 male and 78 female participants were evaluated. In posturographic evaluation, although fall risk score was the highest in group 1 and the lowest in group 3, these differences could not reach statistical significance. However, statistically significant higher fall risk was found in participants with 25(OH)D deficiency (25(OH)D< 30) than in controls (25(OH)D> 30) (p = 0.036). Also a statistically significant correlation was determined between serum 25(OH)D levels and the posturography fall risk scores (p = 0.016, r = − 0, 219).
Conclusion
By using an objective computerized technique, fall risk was found to be higher in young adults with 25(OH)D deficiency than in the controls. Vitamin D deficiency, even when clinically occult, seems to affect balance negatively.
