项目摘要

Strategies for the prevention of osteoporosis have focussed not only on the prevention of bone loss during adult life but also on the increase of high peak bone mass during growth and development. The eating habits and the daily physical activity in childhood and adolescence influence the bone mass. Japanese have a large variety of food in abundance. On the other hand, dieting for fashion purposes, skipping meals, and/or unbalanced diets have become a serious health problem. One such problem is low bone mass in the young. In addition to this, the physical activity in our daily lives has lessened due to a more mechanized and convenient society. Therefore, it might be important to research about the relation between bone mineral density (BMD) and physique, and between BMD and physical activity level. Moreover, it could be essential to enlighten the people as to the dangers of low BMD in the young. The number of elderly patients with osteoporosis might decrease due to the prevention of lo … More w bone mass at a young age.Therefore in this study, the physique, the eating habits, the daily physical activity, the exercise and the BMD (by DXA) of healthy female university students were investigated. The BMD in the subjects with low body mass index (BMI) , who have conserned dieting, was significantly lower than that of the subject with a normal physique. In addition to this, they ate an unbalanced diet, such as low energy intake and excess vitamin A intake. The BMD of the subjects in the exercise group was significantly higher than that of the non-exercise group. There was a significant positive correlation between the lumbar spine BMD and the calcaneus BMD.Moreover, the physique influences not only the lumbar spine BMD but also the calcaneus BMD.These results suggest that not only a sufficient intake of calcium and energy but also a balanced diet, normal physique and high physical activity are important to prevent low BMD.Moreover, it is possible to say that the people who are concerned about their weight or people who are not very active have a lower BMD.In addition to this, an unbalanced diet causes low body weight, and it might be a serious health problem. Taking the measurement of the calcaneus BMD could be also useful and also without risk. The prevention of the low BMD in the young is necessary to prevent osteoporosis in elderly. Therefore, the health screening, including the measurement BMD,and instructions in life style are essential from the young for the prevention of osteoporosis in the future. Less

预防骨质疏松症的策略不仅集中在预防成年期的骨丢失上，而且还集中在生长和发育期间高峰骨量的增加上。儿童和青少年时期的饮食习惯和日常体力活动影响骨量。日本人的食物种类繁多，种类丰富.另一方面，为了时尚而节食、不吃饭和/或不平衡的饮食已经成为严重的健康问题。其中一个问题是年轻人的骨量低。除此之外，由于社会更加机械化和便利，我们日常生活中的体力活动减少了。因此，研究骨密度与体质、体力活动水平的关系具有重要意义。此外，它可能是必不可少的，以启发人们的危险，低骨密度的年轻人。老年骨质疏松症患者的数量可能会减少，这是因为预防了骨质疏松症。 ...更多信息因此，本研究对健康女大学生的体质、饮食习惯、日常体力活动、运动量及DXA骨密度进行了调查。低体重指数（BMI）者经严格节食后，其骨密度明显低于体质正常者。除此之外，他们的饮食不平衡，例如能量摄入量低和维生素A摄入量过多。运动组受试者的BMD显著高于非运动组。腰椎骨密度与跟骨骨密度呈显著正相关，体质不仅影响腰椎骨密度，也影响跟骨骨密度，提示不仅要摄入足够的钙和能量，还要注意均衡饮食、正常体质和高强度的体力活动，以预防低骨密度的发生。这是可能的说，人谁是关心他们的体重或人谁不是很活跃有较低的BMD.除此之外，不平衡的饮食导致低体重，它可能是一个严重的健康问题.测量跟骨BMD也是有用的，也没有风险。预防老年人骨质疏松症的发生，必须预防青年人的低骨密度。因此，从年轻人开始进行包括骨密度测量在内的健康检查和生活方式的指导，对预防骨质疏松症至关重要。少
