Several environmental and genetic factors are determinant, also including sex, hormonal, ethnics, nutritional and lifestyle, may interferer on bone mass of children. However, the pediatric studies that approach the socioeconomic status and the quantitative ultrasound parameters (QUS) are scarce. The aim of this study was to compare the socioeconomic status on bone mass assessed by QUS in boys from 7 to 15 years old. In this cross-sectional study, were evaluated 520 Brazilian boys (9.7±1.5) from different socioeconomic status. The measurements of QUS parameter, amplitude dependent of speed of sound (AD-SoS) were obtained by using the 3th generation of DBM Sonic BP device (IGEA-Carpi, Italy). The socioeconomic status was classified according with the Criteria of Economic Classification Brazil of Brazilian Association of Research Company (ABEP-Brasil). Regarding to the socioeconomic status, most boys (48.8%) were classified in the lower class. The AD-SoS values were significantly higher (P<0.05) in the high class (1926.8±45.1), when compared to the lower class (1906.6±50.8), as shown at Fig. 1.

The results of this study shows that the socioeconomic factors may interferer significantly on the bone mass of this sample.
