Abstract

Calcaneum bone stiffness in 222 young women was investigated by using an ultra-sound bone densitometer (Achilles). Their exercise experiences, amounts of dairy products (including foods which contain a lot of calcium) consumed and 24 questions on their eating attitudes were also analysed. Stiffness showed a significant (p < 0.05) positive correlation with age, BMI and the onset of menarche by polynomial (2) regressions. Using these three variables, expected stiffness was calculated by multiple regression, and according to the differences between the real and expected stiffness, the subjects were divided into three subgroups. Group H which showed higher stiffness, showed significantly (p < 0.05) higher exercise experiences and had the habit of consuming more dairy products and small fish than the other two groups. In all of the subjects, the most important variable which increased the stiffness was the exercise experience at junior high school and the next was the habit of eating small fish. The subjects who customarily ate their meals with their families were more likely to eat small fish. These findings suggest that family eating habits should be noticed not only in post-menopausal women, but also in young girls.

【从生活方式的角度分析年轻女性跟骨硬度升高的过程】。
用超声骨密度仪(跟腱)对222例年轻女性的跟骨硬度进行了调查。研究人员还分析了他们的运动经历、乳制品(包括含大量钙的食物)的摄入量以及24个关于他们饮食态度的问题。经多项式(2)回归分析,僵硬度与年龄、BMI、月经初潮时间呈显著正相关(p < 0.05)。利用这三个变量,通过多元回归计算期望刚度,并根据实际刚度与期望刚度的差值将受试者分为三个亚组。H组肌肉硬度较高,运动经历显著(p < 0.05)高于其他两组,且习惯食用更多乳制品和小鱼。在所有受试者中,最重要的增加僵硬的变量是初中的运动经历,其次是吃小鱼的习惯。习惯上与家人一起吃饭的受试者更有可能吃小鱼。这些发现表明,家庭饮食习惯不仅应注意绝经后妇女,也应注意年轻女孩。
