This exploratory, prospective study was set up to determine the relationship between cortisol and catecholamine levels and labor experience and postpartum maternal mood. It was performed at the Coronation Hospital, which serves a low-income urban population in Johannesburg. Blood samples were taken from 189 low-risk primiparous women in active first stage of labor and analyzed for cortisol, norepinephrine, epinephrine and dopamine. The stress hormone levels were then correlated with maternal anxiety, depression and self-esteem scores, and changes associated with mothers' labor experience and pain. Patients who were distressed and required analgesia had higher cortisol levels. Those who described a more positive labor experience at 24 hours also had higher cortisol levels. There were no significant correlations between psychological test scores and stress hormone levels. Both labor pain at the time and a more positive recollected labor experience were associated with high cortisol levels. Cortisol and catecholamine levels in labor did not correlate with postpartum psychological test scores.
