Then you begin to consciously build your bone and a few years later you are -0.3. Women of your age have likely lost bone, but you may have stabilized or maybe just lost bone at a slower rate and now your bones are .3% less dense than the average for your age. I'm not sure if it is based on %, it may be another scale, but my understanding is that the score is a comparison between you and women of your age. It is natural to lose bone as you age, but whether it is a problem depends on how much.
