Low bone density in the young adult female may refl ect attainment of a lower peak bone mass or be secondary to progressive bone loss following attainment of peak bone density. Early bone health is a key determinant of future osteoporosis, optimizing the bone gain by young adulthood and minimizing the bone loss by menopause is the important preventive strategies.
