Osteoporosis is one of the leading health problems in the United States. Approximately half of the peak bone mass is acquired by the end of the second decade of life, making puberty both a critical period for acquisition of bone mineral and an important determinant of future skeletal health. Peak bone mass is largely determined by genetic factors. However, body mass, diet, hormones, and physical activity can all influence bone mass. This paper reviews the recent literature on normal bone acquisition during adolescence.
