Mother-infant separation among mothers with mental illness: An exploratory observational study in Japan.

Mother-infant separation may influence child development and behavior problems. We reviewed charts for 3639 female patients to investigate rates, reasons, and predictors for mothers with mental illness being separated from their infants during the first year after childbirth in Japan. Of 77 patients with childbirth, 26 cases (34%) presented with maternal separation. The most common reason was psychiatric hospitalization. Diagnoses of schizophrenia spectrum disorders or mood disorders were independent contributors for maternal separation. Clinicians should pay particular attention to relapse or onset of psychotic or mood disorders during the perinatal period.
