Soft tissues overlying the hip play a critical role in protecting against fractures during fall-related hip impacts. Consequently, the development of an efficient and cost-effective method for estimating hip soft tissue thicknesses in living people may prove to be valuable for assessing an individual's injury risk and need to adopt preventative measures. The present study used multiple linear stepwise regression to generate prediction equations from participant characteristics (i.e., height, sex) and anthropometric measurements of the pelvis, trunk, and thigh to estimate soft tissue thickness at the iliac crests (IC) and greater trochanters (GT) in younger (16-35 years of age: 37 males, 37 females) and older (36-65 years of age: 38 males, 38 females) adults. Equations were validated against soft tissue thicknesses measured from full body Dual-energy X-ray Absorptiometry scans of independent samples (younger: 13 males, 13 females; older: 13 males, 12 females). Younger adult prediction equations exhibited adjusted R2 values ranging from 0.704 to 0.791, with more explained variance for soft tissue thicknesses at the GT than the IC; corresponding values for the older adult equations were higher overall and ranged from 0.819 to 0.852. Predicted and actual soft tissue thicknesses were significantly correlated for both the younger (R2 = 0.466 to 0.738) and older (R2 = 0.842 to 0.848) adults, averaging ≤ 0.75cm of error. This research demonstrates that soft tissue thicknesses overlying the GT and IC can be accurately predicted from equations using anthropometric measurements. These equations can be used by clinicians to identify individuals at higher risk of hip fractures who may benefit from the use of preventative measures.
臀部上方的软组织在防止与跌倒相关的髋关节撞击导致骨折方面起着至关重要的作用。因此，开发一种高效、经济实惠的方法来估计活体中髋关节软组织的厚度可能有助于评估个体的受伤风险以及是否需要采取预防措施。本研究使用多元线性逐步回归，根据参与者特征（即身高、性别）和骨盆、躯干和大腿的人体测量学测量值，生成预测方程，以估计年轻（16-35 岁：37 名男性，37 名女性）和老年（36-65 岁：38 名男性，38 名女性）成年人在髂嵴（IC）和大转子（GT）处的软组织厚度。通过与独立样本的全身双能 X 射线吸收法扫描（年轻：13 名男性，13 名女性；老年：13 名男性，12 名女性）测量的软组织厚度进行验证。年轻成年人的预测方程显示调整后的 R2 值范围从 0.704 到 0.791，GT 处的软组织厚度具有更大的可解释方差；老年成年人方程的整体值更高，范围从 0.819 到 0.852。对于年轻（R2 = 0.466 到 0.738）和老年（R2 = 0.842 到 0.848）成年人，预测和实际软组织厚度都呈显著相关性，平均误差≤0.75cm。本研究表明，可以通过使用人体测量学测量值的方程准确预测 GT 和 IC 上方的软组织厚度。这些方程可由临床医生用于识别髋部骨折风险较高的个体，这些个体可能受益于预防措施的使用。
