Blacks are known to have an incidence of hip fractures that is one third that of whites. Studies are ongoing to determine the mechanism for greater bone mass that occurs in blacks. Results to date indicate that blacks have a low rate of bone turnover as compared to whites and alteration of the vitamin D-endocrine system, increases in serum immunoreactive PTH, serum 1,25(OH)2D and urinary cyclic AMP and decreases in serum 25-OHD and urinary calcium.

据了解，黑人髋部骨折的发病率是三分之一， 白人的。 研究正在进行中，以确定更大的 黑人的骨量 迄今为止的结果表明， 与白人相比，骨转换率较低， 维生素D-内分泌系统，血清免疫反应性甲状旁腺素增加，血清 1，25（OH）2D和尿环AMP以及血清25-OHD和尿 钙
