Postnatal depression: a Christchurch study.
OBJECTIVE
The aims of the study were to enquire into the incidence of postnatal depression (PND) and factors associated with it, in a New Zealand population.


METHODS
A wide ranging postal questionnaire, which included the Edinburgh postnatal depression scale (EPDS), was administered to a sample of 1330 women 6-9 months after the birth of their babies at Christchurch Women's Hospital, in 1991/2.


RESULTS
Measured on the EPDS, 80% of the women were not depressed, 7% were at a threshold level of depression and 13% were more severely depressed. Only 6% recognised their symptoms as depression. The factors having the greatest association with high depression scores were: depressive symptoms before and during the pregnancy; serious deterioration in the partner relationship after the birth; decreased energy, confidence and happiness levels after the pregnancy; moderate or severe premenstrual tension prepregnancy; frequent nausea in later pregnancy; low education and low income.


CONCLUSIONS
Postnatal depression appears to be more widespread than is generally realised. The findings suggest that, at the time of postnatal checks on the baby, greater use could be made of the EPDS to increase confidence in a diagnosis of depression. Involvement of male partners in the treatment process is highly desirable.
