Peak bone mass and bone mineral density correlates for 9 to 24 year-old Mexican women, using corrected BMD.
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).


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.
