Objective: To determine the age of peak bone mass (PBM) in Mexican women and factors associated with both BMDa and corrected BMD (BMDcorr) at the femoral neck and the spine (L2-L4).
Material and methods: Data on 461 women between 9 and 24 years old was used. An interview was performed and height and weight were measured. BMDa was measured by a densitometer and BMDcorr by the method proposed by Kröger et al. (1992).
Results: PBM at the spine (L2-L4) was observed later than at the femoral neck. Both BMDa and BMDcorr at the lumbar spine correlate with age, socio-economic status, body fat percentage and height. BMDa at the femoral neck correlates with overweight and obesity, body fat percentage, height and moderate physical activity; the same variables were associated with BMDcorr except for height.
Conclusions: The method proposed by Kröger et al. was more precise at the femoral neck than at the spine.
