Disturbed Sleep and Inflammatory Cytokines in Depressed and Nondepressed Pregnant Women: An Exploratory Analysis of Pregnancy Outcomes

Self-reported sleep and plasma cytokines were obtained in a cohort of depressed and non-depressed pregnant women at 20 and 30 weeks gestation. Among depressed women, short sleep duration was associated with higher IL-8, while poor sleep continuity was associated with higher IL-6. Higher IFN-gamma was associated with increase risk of pre-term birth in depressed women.
