The rapid increase of skeletal size connected with accumulation of bone mass, mostly its mineral part, is observed in the period of intensive growth and maturation. The aim of the study is to answer questions about skeletal mineralization and its physiological factors such as maturation in the population of children from Lodz aged 10-13 years as well as decide whether any abnormalities in this aspect can be observed. Material and methods. The study comprised 300 healthy children from primary schools in all the districts of Lodz i.e. 126 boys and 174 girls aged 10-13 years. In all children: medical examination with maturation assessment and quantitative ultrasound of the heel (QUS) were performed. Results of ultrasound parameters ranged from minus to plus 1,0 for sex and age were taken as normal (Z-score). Results. Statistically significant positive correlations between results of the ultrasound parameters and stage of maturation for boys and girls were found. Conclusions. 1. The results of parameters of the quantitative ultrasound of the heel in children aged 10-13 years are significantly correlated with the stage of puberty. 2. In girls more advanced in puberty accumulation of bone mass was lower than in boys; such observation suggests the necessity of continuation of examinations until the end of maturation.
