Cardiff puerperal mood and hormone study. III. Postnatal depression at 5 to 6 weeks postpartum, and its hormonal correlates across the peripartum period.
BACKGROUND
We assessed associations of mood at 5-6 weeks postpartum with peripartum saliva cortisol and progesterone profiles.


METHODS
A prospective study involved 120 primiparous women free of major marital, socioeconomic and health problems, who collected saliva twice daily from 2 weeks before delivery to day 35 postpartum. This allowed intensive characterisation of cortisol and progesterone profiles. At the conclusion of the study, mood was assessed according to standard criteria.


RESULTS
Seven women developed major depression according to DSM-III-R criteria. No associations emerged between progesterone and mood at 5 to 6 weeks. Lower levels of evening cortisol in the immediate peripartum period, were associated with postnatal depression.


CONCLUSIONS
The study provides no support for the treatment strategy of progesterone augmentation following delivery, as a prophylactic against postnatal depression. The HPA axis and its associations with postnatal mood warrants further investigation.
