In this study, ultrasound measurements of the calcaneus of 712 healthy postmenopausal Polish women aged 50-85 years (mean age 59.5 years) were performed. Broadband ultrasound attenuation (BUA) and speed of sound (SOS) were obtained with a Lunar Achilles machine. The women in the study were volunteers evaluated at the Osteoporotic Centre for screening purposes. The results showed a decrease in ultrasound values within the age range 52-74 years for BUA (9.8%) and SOS (1.9%). Simple linear regression analysis showed a negative, significant correlation with age for BUA (r=-0.36) and SOS (r=-0.38). Years since menopause (YSM) showed significant correlations with BUA and SOS (r=-0.33 and -0.35, respectively). Using multiple regression analysis, the following equations were obtained: BUA=66.04 - 0.31Age + 0.06Weight - 0.18 YSM + 0.27Height + 0.52 Body mass index and SOS=1547.17 - 1.02Age + 0.38Weight - 0.48 YSM. Several weak, but significant, correlations between ultrasound values and weight, height and body mass were noted (r ranged from 0.09 to -0.29). A decrease of ultrasound values was expressed mainly in the first 6-10 years of the postmenopause period. The pattern of this decrease was similar to data published by other authors, but values in postmenopausal Polish women are slightly lower.
在本研究中，对712名年龄在50 - 85岁（平均年龄59.5岁）的波兰健康绝经后女性的跟骨进行了超声测量。使用Lunar跟腱仪获得宽带超声衰减（BUA）和声速（SOS）。研究中的女性为在骨质疏松症中心接受评估的志愿者，目的是进行筛查。结果显示，在52 - 74岁年龄范围内，BUA下降了9.8%，SOS下降了1.9%。简单线性回归分析表明，BUA（r = -0.36）和SOS（r = -0.38）与年龄呈显著负相关。绝经年限（YSM）与BUA和SOS也呈显著相关（分别为r = -0.33和 -0.35）。通过多元回归分析，得到以下方程：BUA = 66.04 - 0.31年龄 + 0.06体重 - 0.18 YSM + 0.27身高 + 0.52体重指数，SOS = 1547.17 - 1.02年龄 + 0.38体重 - 0.48 YSM。超声值与体重、身高和体重指数之间存在若干微弱但显著的相关性（r范围为0.09至 -0.29）。超声值的下降主要发生在绝经后的前6 - 10年。这种下降模式与其他作者发表的数据相似，但波兰绝经后女性的数值略低。
