Skeletal measurements by quantitative ultrasound in adolescents and young women with anorexia nervosa.

Objective: To compare quantitative ultrasound (QUS) measurements in adolescents with anorexia nervosa (AN) with that in healthy control subjects and to determine the utility of QUS as a tool to evaluate skeletal status in these patients.

Study Design: Female adolescents with AN (n = 41) and healthy control subjects (n = 105) were recruited. Speed of sound (SOS) was measured at the radius and tibia.

Effects of nutrition, puberty, and gender on bone ultrasound measurements in adolescents and young adults.

Purpose: Quantitative ultrasound (QUS) evaluation of bone is attractive for evaluating skeletal status in adolescents, but its use is limited in the United States due to sparse pediatric reference data. This study evaluated associations between radial and tibial speed of sound (SOS) measurements via QUS and demographic, anthropometric and nutritional variables.

Methods: We enrolled 151 healthy participants, aged 11-26 years, during routine visits to an urban adolescent clinic.
