在这项以人群为基础的研究中，研究了39名女孩和48名男孩的儿童体重和身高、青少年骨量和肌肉力量之间的关系。采用双x线吸收仪测量全身和股骨颈骨量（骨矿物质含量、BMC和骨密度）。测量股四头肌力量。测量时女孩和男孩的平均年龄为15.1岁。研究结果分别与儿童时期（出生至6岁）的体重和身高数据联系起来，这些数据来自社区卫生记录。儿童期体重可预测青少年总BMC （total body BMC， TBMC）。然而，当将儿童体重和总体骨密度（TBMD）相关联时，情况并非如此，这表明生长决定了骨骼的大小，而骨包膜内的密度在更大程度上受其他因素的支配。此外，在多元回归模型中，我们发现儿童期体重和身高的综合效应与青春期股四头肌力量显著相关。
In this population-based study, the relationship between childhood weight and height, and adolescent bone mass and muscle strength have been studied in 39 girls and 48 boys. Total body and femoral neck bone mass measurements (bone mineral content, BMC and bone mineral density, BMD) were made by dual X-ray absorptiometry. Quadriceps muscle strength was measured. Mean age at the time of measurement was 15.1 years for girls and boys. Results were individually linked to data on childhood (birth to 6 years of age) weight and height, taken from community health records. Childhood weight was found to be predictive of adolescent total body BMC (TBMC). However, this was not the case when correlating childhood weight and total body BMD (TBMD), suggesting that growth determines the size of the skeleton, whereas the density within that bone envelope is to a greater extent governed by other factors. Further, in a multiple regression model we found that the combined effect of childhood weight and height was significantly correlated with adolescent quadriceps muscle strength.
