title: [Respective importance of the different risk factors for osteoporosis].
abstract: Among the factors which influence accumulation of bone mass, genetic factors related to race and family are preponderant: they account for approximately 80% of the variance observed in adulthood. At puberty, nutritional factors and physical activity modulate the accumulation of bone and determine whether or not optimal bone mass is achieved. In women, estrogen deprivation following menopause, and also more minor disorders of gonad function, are the main causes of decreased bone mass; their respective contributions are analyzed.
