	Serum 25-Hydroxyvitamin D is Positively Associated with Bone Mineral 
Density in White Men

Reference: 	"Serum 25-hydroxyvitamin D and Bone Mineral Density in a 
Racially And Ethnically Diverse Group of Men," Hannan MT, Holick MF, et 
al, J Clin Endocrinol Metab, 2007 Nov 6; [Epub ahead of print]. 
(Address: Institute for Aging Research, Hebrew Senior Life, Boston, MA, 
USA).

Summary: 	In a population-based study involving 331 Black, 362 Hispanic, 
and 421 White men (mean age = 48 years), a significant correlation was 
observed between serum 25-hydroxyvitamin D [25(OH)D] concentrations and 
bone mineral density (BMD) in White men alone. BMD and 25(OH)D 
concentrations were assessed in all participants. Mean 25(OH)D levels 
were lower in Black and Hispanic men compared to White men. 
Additionally, a higher percentage of Black (44%) and Hispanic men (23%) 
had 25(OH)D levels in the lowest quartile, compared to 11% of White men. 
After adjusting for potential confounders, a positive correlation 
between 25(OH)D levels and BMD was observed in White men. On the other 
hand, no associations were observed between 25(OH)D and BMD in Black or 
Hispanic men at any bone site. Thus, the results of this study suggest 
that serum 25(OH)D levels is positively correlated with BMD in White 
men. Vitasearch Comment: The reason(s) why 25(OH)D concentrations did 
not show an y relationship with BMD in black or hispanic men warrants 
further study.
