目的骨矿物质密度（BMD）和框架尺寸是未来骨骼健康的重要预测因素，较小的框架尺寸和较低的BMD与后期脆性骨折的风险较高相关。我们测试的影响，身体大小，习惯性使用，和生活史上的框架大小和皮质骨密度的桡骨和胫骨的健康成年绝经前women.MethodsWe使用人体测量和生活史数据从123名妇女（年龄18 - 46）从农村波兰。使用标准技术测量身高、体重和体脂。使用调查记录生活史因素。握力被测量为习惯性活动的代表，腕宽为骨骼框架大小。使用定量超声测量桡骨远端三分之一点和胫骨中点的皮质BMD（报告为声速，SoS）。结果桡骨SoS较高（平均评分为3.2 ± 1.6），但胫骨SoS平均（平均评分为0.35 ± 1.17）。SoS与年龄无关，尽管在调整身高后腕宽与年龄呈正相关。Radius SoS与身体尺寸、习惯使用或生活史因素无关。腕宽与体型（所有p<0.05）、瘦体重和握力相关。胫骨SoS与身高相关。生活史因素与框架大小或皮质SoS. ConclusionsHababetuses和整体的身体大小更强烈地与框架大小和皮质SoS比生活史因素在这个样本中的健康成年女性。
ObjectiveBone mineral density (BMD) and frame size are important predictors of future bone health, with smaller frame size and lower BMD associated with higher risk of later fragility fractures. We test the effects of body size, habitual use, and life history on frame size and cortical BMD of the radius and tibia in sample of healthy adult premenopausal women.MethodsWe used anthropometry and life history data from 123 women (age 18‐46) from rural Poland. Standard techniques were used to measure height, weight, and body fat. Life history factors were recorded using surveys. Grip strength was measured as a proxy for habitual activity, wrist breadth for skeletal frame size. Cortical BMD was measured at the one‐third distal point of the radius and mid‐point of the tibia using quantitative ultrasound (reported as speed of sound, SoS).ResultsRadial SoS was high (meant‐score 3.2 ± 1.6), but tibia SoS was average (meant‐score 0.35 ± 1.17). SoS was not associated with age, although wrist breadth was positively associated with age after adjusting for height. Radius SoS was not associated with measures of body size, habitual use, or life history factors. Wrist breadth was associated with body size (p< .05 for all), lean mass, and grip strength. Tibia SoS was associated with height. Life history factors were not associated with frame size or cortical SoS.ConclusionsHabitual use and overall body size are more strongly associated with frame size and cortical SoS than life history factors in this sample of healthy adult women.
