title: Behavior of phalangeal bone ultrasound in normal women with relation to gonadal status and body mass index.
abstract: The behavior of phalangeal bone ultrasound was studied, measured by amplitude-dependent speed of sound (Ad-SOS) in meters per second, in 324 normal women (mean age 48.9 +/- 13.7 years) classified by gonadal status (premenopausal, perimenopausal and postmenopausal) and body mass index (BMI, thin, normal, overweight and obese). Ad-SOS differed significantly with gonadal status and BMI (p<0.0001 for all). In the overall group of women, Ad-SOS correlated negatively with age (r=-0.84, p<0.0001), weight (r=-0.16, p<0.005), BMI (r=-0.27, p<0.0001), and tartrate-resistant acid phosphatase concentration (TRAP) (r=-0.35, p<0.0001). The negative correlation remained significant in the groups separated by gonadal status, but to a lesser extent. After adjusting for confounding variables such as age and weight, Ad-SOS was dependent on age (but not on weight or BMI) in the overall group of women and in the gonadal status groups. In conclusion, Ad-SOS values differed significantly with gonadal status and BMI, and correlated negatively with TRAP. The plot of Ad-SOS against age differed significantly with gonadal status as well as BMI.
