To present reference values and correlations with body composition, blood variables and lifestyle factors.
Two random population samples from Göteborg, Sweden, one comprising 184 men and 455 women aged 25-64 years (MONICA) and the other 860 women aged 55-82 years (BEDA) were studied.
Calcaneal ultrasound measurement (LUNAR Achilles) and bioimpedance were measured. Smoking habits, coffee consumption, physical activity, psychological stress, education and marital status, as well as blood lipids, blood pressure, and fractures were studied.
Broadband ultrasound attenuation and stiffness were higher in men than in women (P < 0. 001), but speed of sound did not differ between sexes. Speed of sound, broadband ultrasound attenuation and stiffness decreased with age (P < 0.001). In both sexes speed of sound, broadband ultrasound attenuation and stiffness correlated positively to body size variables, and negatively with smoking in women after adjustment for age. Speed of sound, broadband ultrasound attenuation and stiffness were positively related to physical activity in both sexes, and these relationships were the only ones that remained in multivariate analyses in addition to age (negative). Osteoporotic fractures increased with age. Speed of sound, broadband ultrasound attenuation and stiffness were lower amongst women with osteoporotic fractures.
Speed of sound, broadband ultrasound attenuation and stiffness decreased with age and increased with physical activity, but body weight and height were not correlated in multivariate analyses. Osteoporotic fractures increased with age and were associated with lower calcaneal ultrasound values.
呈现参考值以及与身体成分、血液变量和生活方式因素的相关性。
来自瑞典哥德堡的两个随机人群样本，一个样本包含184名年龄在25 - 64岁的男性和455名女性（MONICA研究），另一个样本包含860名年龄在55 - 82岁的女性（BEDA研究）。
测量跟骨超声（LUNAR跟腱超声仪）和生物电阻抗。研究吸烟习惯、咖啡摄入量、身体活动、心理压力、教育程度和婚姻状况，以及血脂、血压和骨折情况。
男性的宽带超声衰减和硬度高于女性（P < 0.001），但男女声速无差异。声速、宽带超声衰减和硬度随年龄增长而降低（P < 0.001）。在调整年龄后，男女的声速、宽带超声衰减和硬度与身体大小变量呈正相关，而在女性中与吸烟呈负相关。声速、宽带超声衰减和硬度在男女中均与身体活动呈正相关，并且在多变量分析中，除年龄（呈负相关）外，这些关系是仅有的保持显著的关系。骨质疏松性骨折随年龄增加。骨质疏松性骨折女性的声速、宽带超声衰减和硬度较低。
声速、宽带超声衰减和硬度随年龄增长而降低，随身体活动增加而升高，但在多变量分析中体重和身高无相关性。骨质疏松性骨折随年龄增加，且与较低的跟骨超声值相关。
