Study Summary

Aim 1: To evaluate the effect of antipsychotic treatment group on Activity Energy Expenditure. The project hypothesizes that subjects treated with olanzapine will demonstrate a greater decrease in AEE over time than subjects treated with ziprasidone, due at least in part to sedating effects of olanzapine. Aim 2: To evaluate the effect of antipsychotic treatment group on Energy Intake. The project hypothesizes that subjects treated with olanzapine will demonstrate a greater increase in EI over time than subjects treated with ziprasidone, based on higher histamine type 1 (H1) receptor affinity of olanzapine and the relationship between H1 affinity and hunger and/or satiety.
