Abstract
Ultrasound bone measurement in healthy Croatian children and adolescents has been
evaluated. Relationships between pubertal status, anthropometry, nutrition, and physical
activity with ultrasound bone parameter were analyzed. A total number of 501 children
and adolescents of both sexes participated in the study. There were 244 prepubertal
children (120 boys and 122 girls) and 259 postpubertal adolescents (112 boys and 147
girls). Anthropometric measurements included height, weight, percent of fat tissue,
and body mass index. Quantitative ultrasound measurements of the heel (nondominant
side) were performed using “Sahara” sonometer and included speed of sound (SOS), broad-band
ultrasound attenuation (BUA), and calculated bone stiffness (QUI). Dietary data were
assessed using specially designed semiquantitative food frequency questionnaire calculations
based on the daily intakes of calcium, carbohydrates, fats, and proteins. Quantitative
ultrasound bone measurements (BUA, SOS, and QUI) were similar in prepubertal boys
and girls. Adolescent boys had significantly higher BUA (P<.01) than girls. The percentage of children and adolescents who consumed more than
1,000 mg of calcium per day were 54.8% and 48.7%, respectively. Body weight and pubertal
status and activity were significantly correlated with bone stiffness but not the
calcium intake. In this study, bone stiffness in children and adolescents is determined
by pubertal status and body weight, rather than by calcium intake.
