Nevertheless, its deficiency is linked to increased bone turnover through the upregulation of RANK ligands by osteoblasts. This study aimed to (i) evaluate vitamin D status in young adults and (ii) assess the association between vitamin D deficiency and bone turnover markers receptor activator of nuclear factor-\u03baB ligand (RANKL), RANK, and the osteoprotegerin (OPG) in determining bone mineral density.<\/jats:p>\n <\/jats:sec>\n \n Materials and Methods:<\/jats:title>\n This cross-sectional study involved 474 participants from the East Khasi Hills district, Meghalaya. Vitamin D levels were measured using the UniCel DxI 800 system, while OPG, RANK, and RANKL were assessed through enzyme-linked immunosorbent assay (ELISA). Additionally, a whole-body dual X-ray absorptiometry (DEXA) scan determined bone mineral density. Vitamin D deficiency was categorised as <20 ng\/ml, insufficiency as 20\u201329 ng\/ml, and sufficiency as \u226530 ng\/ml.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n \n Findings indicated 54.6% vitamin D deficiency and 35.4% insufficiency in young adults. Osteoporosis affected 26%, and 67% exhibited osteopenia. A weak positive correlation was found between vitamin 25(OH) D and bone mineral density T score (r = 0.16, r\n 2<\/jats:sup>\n = 0.02,\n P<\/jats:italic>\n = 0.44). Additionally, moderately weak correlations were observed between serum vitamin D and OPG (r = \u20130.42, r\n 2<\/jats:sup>\n = 0.18,\n P<\/jats:italic>\n < 0.001) and between vitamin D and RANKL (r = \u20130.13, r\n 2<\/jats:sup>\n = 0.01,\n P<\/jats:italic>\n = 0.18).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion:<\/jats:title>\n The study suggests that vitamin D deficiency diminishes bone mineral density by promoting RANKL-RANK osteoclastogenesis and upregulating OPG expression. As young adults form a significant workforce, creating awareness is crucial for maintaining optimal health.<\/jats:p>\n
