本研究的目的是调查影响初中生（男生、女生月经初潮和女生未月经初潮）骨声评价指数（OSI）的因素。方法爱媛县共有9,743名学生（男生4,974名，女生4,769名）参加了这项研究。我们使用OSI测量体重指数（BMI）和跟骨骨量。同时，参与者回答了一份关于年龄、性别、月经初潮、运动习惯、牛奶摄入量和前一年骨折史的问卷。为了确定影响OSI的因素，我们使用多元线性回归（MLR）分析计算了个体标准化偏回归系数（β）。结果对于男孩，MLR显示BMI（β = 0.300），年龄（β = 0.260），目前的运动习惯（β = 0.106），和每天在小学的牛奶摄入量（β = 0.085）在统计学上显著影响OSI。对于初潮女孩，BMI（β = 0.302）、当前运动习惯（β = 0.237）、年龄（β = 0.140）和前一年骨折（β = 0.036）影响OSI。对于未达到初潮的女孩，目前的运动习惯（β = 0.242），BMI（β = 0.135）和年龄（β = 0.085）影响OSI。BMI、运动习惯、年龄是影响OSI的共同因素。特别是对于女孩来说，运动习惯对OSI有很大的影响。
ObjectiveThe purpose of this study is to investigate factors influencing the osteo-sono assessment index (OSI) in junior high school students (boys, girls who had reached menarche, and girls who had not).MethodsA total of 9,743 students (4,974 boys and 4,769 girls) in Ehime Prefecture participated in this study. We measured body mass index (BMI) and calcaneal bone mass using OSI. In parallel, participants answered a questionnaire relating to age, sex, menarche, exercise habits, milk intake, and history of bone fractures during the preceding year. To determine the factors influencing OSI, we calculated an individual standardized partial regression coefficient (β) using multiple linear regression (MLR) analysis.ResultsFor boys, MLR showed that BMI (β = 0.300), age (β = 0.260), current exercise habits (β = 0.106), and milk intake per day in primary school (β = 0.085) statistically significantly influenced OSI. For girls who had reached menarche, BMI (β = 0.302), current exercise habits (β = 0.237), age (β = 0.140), and bone fracture during the preceding year (β = 0.036) influenced OSI. For girls who had not reached menarche, current exercise habits (β = 0.242), BMI (β = 0.135), and age (β = 0.085) influenced OSI.ConclusionsThere were differences between the factors related to OSI among boys, girls who had reached menarche, and girls who had not. BMI, exercise habits, and age were the common factors related to OSI. Particularly for girls, exercise habits had a great influence on OSI.
