近年研究表明,维生素K(VK)不仅有凝血功能,而且通过参与VK依赖性骨蛋白的羧化影响骨代谢。膳食VK摄入不足,机体VK水平低,则骨质疏松及骨折的危险性增加[1]。了解我国老年人维生素K(VK)营养状况,可为防治骨质疏松提供科学依据。1对象与方法1.1调查对象2004年4月调查沈阳市某社区
Recent studies show that vitamin K (VK) not only has coagulation function, but also affects bone metabolism by participating in carboxylation of VK-dependent bone protein. Insufficient intake of dietary VK and low levels of VK in the body increase the risk of osteoporosis and fractures [1]. Understanding the nutritional status of vitamin K (VK) in our country can provide a scientific basis for the prevention and treatment of osteoporosis. 1 Subjects and Methods 1.1 Survey In April 2004 survey of a community in Shenyang
