The contraceptive methods (MACs) are used hormonal largely due to the high efficiency. In recent years numerous studies have been published about contraceptives, bone loss and fracture risk, they often are administered for prolonged periods and in a stage of life that has not yet reached peak bone mass formation, as in use in adolescent women.Among the injectable hormonal MACs, the depot medroxyprogesterone acetate (DMPA) contraception is the most studied in relation to effects on mienral density (BMD). Concern about the effect of DMPA on BMD began soon after the approval of the use of this medication in the U.S. in 1992, and is basically the state of hypoestrogenism caused by the method.Studies have shown an increase in body weight, but there is almost no evidence on the body composition of AMDP system users. The assessment of body composition is of great importance in checking the nutritional status, prediction of bone mass and development of appropriate conduct, since the excess fat is associated with several chronic diseases.A diet rich in calcium and vitamin D associated with physical activity impact, are proven methods to reduce the loss of BMD. The use of MACs hormone remains controversial, there is no consensus on the specific use of DMPA and bone mass. Given this aspect is relevant to verify the possible effects of habits such as physical activity, sun exposure and calcium intake, as well as the presence of vitamin D deficiency in women using DMPA compared to women without the use of method hormonal.
