Postpartum Hostility and Prolactin

Abstract

In a previous study ten women with hyperprolactinemia and amenorrhea had significantly higher Symptom Questionnaire scores for depression, hostility and anxiety than patients with amenorrhea only and a matched nonpatient employees group. The hyperprolactinemic patients and employees were compared with ten women on their seventh day after childbirth who had been matched for sociodemographic variables and had similar prolactin levels. Hostility was significantly higher in postpartum patients than employees and did not differ significantly from that of women with hyperprolactinemic amenorrhea. Postpartum hyperprolactinemic women did not differ significantly from the employees for anxiety and depression, which was significantly lower than in the amenorrheic patients. In several mammals aggression occurs concurrently with lactation. The studies in humans suggest an association of high prolactin levels with hostility.
