title: [Body mass index and quantitative osseous ultrasonography of the phalanges in Lebanese post-menarcheal adolescent girls].
abstract: OBJECTIVE
  To explore the relation between body mass index and phalanx ultrasound measurements in a group of Lebanese post-menarchal girls.
  
  
  RESULTS
  Amplitude-dependent speed of sound (AD-SoS) and bone transmission time (BTT) were measured in 168 post-menarchal girls aged 12-17 years using a DBM sonic bone profiler device. Anthropometrical characteristics (weight and height) were measured. Age and maturation index (years since menarche) were positively related to AD-SoS and BTT (p < 0.01). AD-SoS values were negatively related to BMI and body weight (r = -0,27; p < 0.001 and r = - 0,25; p < 0.001 respectively). There was no relation between BTT values and neither BMI nor body weight. Overweight girls (n = 36) had lower AD-SoS values than normal-weight girls (n = 122) (1994 +/- 87 m x sec(-1) vs 2041 +/- 82 m x sec(-1) respectively; p < 0.01). Obese girls (n = 10) had lower AD-SoS values than normal-weight girls (n = 122) (1976 +/- 96 m x sec(-1) vs 2041 +/- 82 m x sec(-1) respectively; p < 0.05).
  
  
  CONCLUSIONS
  In this group of Lebanese post-menarchal girls, AD-SoS values are inversely correlated to BMI while BTT values were not related to BMI.
