282名女医护生骨质疏松知识及骨密度影响因素分析

An analysis of osteoporosis knowledge and the influence factors of bone mass density in 282 female undergraduate doctors and nurses

目的了解医护生对骨质疏松知识的认知情况,并探讨饮食牛奶和运动对骨密度的影响。方法在对282名医护生进行问卷调查的同时,进行L2-4、股骨近端、桡骨远端骨密度测定。结果临床生与护理生在某些问题上的认知率差异有显著性;饮食牛奶量不同,L2-4、股骨近端、桡骨远端骨密度具有组间差别(P<0.05);达一定运动强度的运动方式,运动时间不同,股骨近端、桡骨远端具有组间差别(P<0.05),L2-4无差别。结论应加强医护生的健康教育,并补充充足的牛奶以及适当的运动,以增加峰值骨量,延缓骨质疏松的发生。

Objective To understand the knowledge about osteoporosis and research about the effect of physical activity and milk on bone mass density in 282 female undergraduate doctors and nurses. Methods 282 female undergraduate doctors and nurses were surveyed by the questionnaire. At the same time, all of them were determined by dual-energy X-ray absorptionetry（ include lumbar2 - 4, thighbone neck, wards triangle, troch, radius）. Results On some questions,the cognition rate about osteoporosis knowledge of undergraduate doctors was higher than that of undergraduate nurses ; There were significant difference in the BMD of lumbar2 - 4, upper femur and radius, because the milk intake was different;The BMD（include upper femur and radius）in three groups were significantly different, becase of the different activity level. Conclusions Health education, adequate milk and physical exercise elevate peak bone mass and slow down the progress of osteoporosis.
