The childhood is an important period for bone mass acquisition, and this tissue may be influenced by the nutritional status. However, the relation between the nutritional status and the bone parameters of quantitative ultrasound (QUS) remains unclear. The aim of this study was to verify the influence of nutritional status on bone mass assessed by QUS in male children from 7 to 10 years old. The sample consisted of 461 Brazilians pre-pubertal schoolchildren (8.30±1.13 years). The nutritional status was classified according to extended International BMI cut-offs (Cole & Lobstein 2012). For the bone mass measurements was used the QUS of proximal hand phalanges, using the DBM Sonic BP (IGEA, Carpi, Italy) device, which provides the parameter amplitude-dependent speed of sound (AD-SoS). Most subjects (64%) presented a normal nutritional status (15.8 kg/m2), 11.3% at thinness (13.7 kg/m2), and 14.8% at overweight (19 kg/m2) and 9.5% at obese (23 kg/m2). The obese subjects (1875.4±43.76 m/s) presented lower values (P<0.04) of AD-SoS when compared to the other groups (1902.2±49.2; 1896.3±48.47; 1900.7±49.5 m/s, thinness, normal e overweight, respectively), as shown at Fig. 1.

The results presented in this study shows that the nutritional status may interferer negatively at the bone mass parameters, and may implicate the bone health in adulthood. Preventive actions must take place with children to minimize the negative effects of obesity.
