The objective of this study is to examine the role of the endogenous mu-opioid system in mediating the relationship between metabolic dysfunction and depressive symptoms in reproductive aged women. PET image data was unable to be analyzed due to PET equipment replacement midway through study, leaving PET images collected at beginning of study incompatible with PET images collected later in study. Due to insufficient enrollment in treatment arms, the 20 or 40 week data was unusable for analytic goals, so the study was re-framed for what could usefully be learned about baseline characteristics among the study populations and the originally planned outcome measures were amended to only to those that related to understanding the baseline population.
