The aim of this study was to evaluate the association of food consumption and body composition on bone parameters in adolescent soccer players. 148 male soccer players aged 12 to 18 years participated in the study. Body composition were assessed by dual energy X-ray absorptiometry, comprising bone mineral density (BMD) and bone mineral content (BMC) of total body without head (TBLH), lumbar spine (L1-L4) and right femoral neck (RFN). The bone geometry variables measured were Femoral Strength Index (FSI), Buckling Ratio (BR), Section Modulus (Z), Cross-sectional Moment of Inertia (CSMI) and Cross-sectional Area (CSA). Food intake was analyzed using the 24-hour food recall. Somatic maturation was estimated by the Peak Height Velocity equation. For the statistical analysis, the Stepwise multiple linear regression was used, with p-value of <0.05. Regarding food consumption, there was a high protein intake and low calcium intake. Lean mass was a predictor of BMC of TBLH (R² = 0.524), L1-L4 (R² = 0.492) and RFN (R² = 0.405); BMD of L1-L4 (R² = 0.407) and RFN (R² = 0.27); Z (R² = 0.683), CSMI (R² = 0.630) and CSA (R² = 0.640). There was a negative correlation between protein intake with bone mass and bone geometry parameters. In adolescent soccer players, lean mass was a predictor of bone parameters, and high protein intake was negatively associated with bone mass and geometry.
