OSTEOPOROSIS IN MEN

这个子项目是利用由NIH/NCRR资助的中心拨款提供的资源的许多研究子项目之一。子项目和调查员(PI)可能从另一个NIH来源获得了主要资金，因此可能会出现在其他CRISE条目中。列出的机构是针对中心的，而不一定是针对调查员的机构。行为和饮食习惯会导致骨密度的丧失，从而增加老年男性骨折的风险。这项研究建议建立一个由1000名老年男性组成的队列，在四年的时间里进行纵向跟踪，以：1.评估低骨密度的风险因素；2.确定与随着时间的推移骨密度下降相关的因素；3.确定与骨超声测量随时间变化相关的因素(一种衡量骨骼“质量”的指标)。

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).
