NCT00399776

Brief Summary

We hypothesize that antipsychotic induced hyperprolactinemia can decrease bone mineral accrual and decrease bone mineral content (BMC) in adolescents on antipsychotic therapy. Specifics Aims

  1. 1.To determine if antipsychotic therapy leads to decreased bone mineral accrual and decreased bone mineral content in a group of adolescents on antipsychotic therapy by comparing them to an ethnicity, gender and pubertal stage matched control group.
  2. 2.To determine the relationship between serum concentrations of prolactin, sex steroids and bone turnover markers in adolescents on antipsychotic therapy and an ethnicity, gender and pubertal stage matched control group.
