Schematic representation of bone mass changes with age

Schematic representation of the bone mass life-line in individuals who achieve their full genetic potential for skeletal mass (red, diagonal line fill) and in those who do not (blue, solid fill). The magnitude of the difference between curves is not intended to be to scale. Along the bottom of the graph are several factors known to be particularly relevant to bone strength. In older individuals, the increased risk of falls also contributes to the fracture risk.
