Vitamin D and Trabecular Bone Score in a Group of Young Lebanese Adults.

The relationship between vitamin D and trabecular bone score (TBS) in young adults remains unclear. The aim of this study was to explore the relationship between 25-hydroxyvitamin D [25(OH)D] serum levels and TBS in a healthy adult population. A total of 54 men and 61 women whose ages range from 18 to 35 participated in the present study. Participants with 25(OH)D insufficiency (between 21 and 29 ng/mL) were 55.7%, and those with 25(OH)D deficiency (≤20 ng/mL) were 11.4%. TBS positively correlated with 25(OH)D in men (r = 0.393; p <0.05) and women (r = 0.324; p < 0.05). In both genders, TBS was significantly higher in 25(OH)D-sufficient participants (≥30 ng/mL). The present study provides evidence that vitamin D positively affects bone health and suggests that maintaining adequate vitamin D status may be essential for optimal TBS values.
