Abstract

In this investigation, we relate transverse midshaft diameter of the femur, age, and weight in a sample of 183 children from Central Ohio. Age and femur diameter considered separately are similar in their ability to predict weight. Considering all sex and ancestry groupings (male, female, white, black), age explains between 90% to 96.8% of the variation in weight while femur diameter explains between 93% to 97.4%. However, estimates of individual weight from age or femur diameter have very large 95% prediction limits. Using age and femur diameter together results in a greater proportion of the variation in weight explained, 97.7% for the total sample, but the 95% prediction limits are similar to those using femur diameter alone.

摘要

在本次调查中，我们研究了俄亥俄州中部183名儿童样本的股骨中轴横径、年龄和体重之间的关系。单独考虑年龄和股骨直径时，它们预测体重的能力相似。考虑所有性别和种族分组（男性、女性、白人、黑人），年龄解释了体重变化的90%至96.8%，而股骨直径解释了93%至97.4%。然而，根据年龄或股骨直径对个体体重的估计有非常大的95%预测区间。同时使用年龄和股骨直径能解释更大比例的体重变化，总样本为97.7%，但95%预测区间与单独使用股骨直径时相似。
