OSTEOPOROSIS IN MEN

该子项目是利用 NIH/NCRR 资助的中心拨款提供的资源的众多研究子项目之一。子项目和研究者 (PI) 可能已从另一个 NIH 来源获得主要资金，因此可以在其他 CRISP 条目中出现。列出的机构是中心的机构，不一定是研究者的机构。行为和饮食习惯会导致骨矿物质密度下降，从而增加老年男性骨折的风险。本研究拟建立一个由 1000 名老年男性组成的队列，在四年内进行纵向随访，以： 1. 评估低骨矿物质密度的危险因素 2. 确定与骨密度随时间下降相关的因素； 3. 确定与骨超声测量随时间变化相关的因素（骨“质量”的测量）。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Behavioral and dietary habits contribute to the loss of bone mineral density that increases the risk of fractues in older men. This study proposes to establish a cohort of 1000 elderly men to be followed longitudinally over a four-year period to: 1. evaluate risk factors for low bone mineral density 2. indentify factors associated with decrease in bone density over time and; 3. identify factors related to changes in bone ultrasound measurements over time (a measure of the "quality" of bone).
