Socioeconomic Status Is Associated With Reward Processing, Interleukin 1β, Striatal Connectivity, and Antidepressant Outcomes in Individuals With Major Depressive Disorder: A CAN-BIND-1 Report.

ABSTRACT:

Background

Major depressive disorder (MDD) is a common condition with heterogeneous risk factors. Socioeconomic status (SES) is one such risk factor, which is negatively linked to MDD treatment outcomes and symptom severity. SES is associated with altered resting-state functional connectivity (RSFC) in reward-processing circuitry and elevated proinflammatory cytokine levels in individuals without depression. However, how the negative consequences of low SES exacerbate MDD psychopathology is poorly understood.

Methods

Data on SES (household income and education), depression severity, self-reported reward processing, serum proinflammatory cytokine levels, and neuroimaging for 323 adult participants (211 patients with MDD receiving open-label escitalopram, 112 control participa
