Peak Bone Mass in Women
Most skeletal growth and mineralization occurs in the first two decades of life. During fetal development and the first year there is rapid bone growth. This continues, but at a slower rate, throughout childhood and approaching puberty.
Young adolescents obtain 60% of their total bone mass during the pubertal growth spurt. This slows toward completion around age 18, but small amounts of mineralization continue until age 30 or so. This is the time of peak bone mass, when the lifetime maximum amount of bone mineralization is achieved.
For women, from the time of peak bone mass until she stops menstruating permanently (menopause), there is very little change in bone mass. However, after menopause, there is usually a period of rapid bone loss for a few years. This eventually slows down and is more consistent with the losses experienced in men due to normal aging.
