Postnatal depression: a South Australian prospective survey.

The purpose of this study was to determine the prevalence of postnatal depression (PND) and to assess self-esteem in the early postnatal period and at 6 weeks postpartum and PND at 6 months postpartum. Women giving birth to term babies over a 6-month period, completed an Edinburgh postnatal depression scale (EPDS) and a Rosenberg self-esteem scale in hospital, at 6 weeks postpartum and an EPDS only at 6 months postpartum. A total of 235 women participated in the study of which 222 (95%) returned their questionnaire at 6 weeks postpartum and 192 (82%) at 6 months postpartum. Characteristics of the women and their pregnancy outcome are presented. The EPDS identified a depressed mood in 9% of women in hospital and at 6 weeks postpartum (95% CI 5.3%-12.8%). At 6 months this had increased to 10% (95% CI 7.8%-12.2%).
