The mean bone density of long term Depo - Provera users is lower than for women not using Depo, irrespective of bleeding patterns. However bone density increases again upon discontinuation of Depo as a contraceptive method.
Based on evidence so far, the bone mineral density of adolescents using Depo is lower than those using other forms of contraception such as the combined oral contraceptive pill. Because adolescence and young adulthood is an important time in the development of our peak bone mass, it has been suggested that Depo may not be the ideal choice of contraception long term for this population.
Interestingly, long term Depo users examined after menopause did not display lower bone density than those women who had never used Depo, re enforcing the idea that bone density recovers after discontinuation. Also no excess of fractures have been demonstrated in long term users to date.
Use in adolescents at this stage, is seen by the World Health Organisation as more advantageous than the risks of not using contraception. Common practice would be to re-evaluate the risk/benefit profile of young users every few years. In addition Depo may not be considered an acceptable choice for a person considered at high risk of osteoporosis.
