Additional research needed to evaluate the effect of oestrogens for the prevention and treatment of postpartum depression but synthetic progesterones should not be administered.
Postpartum depression is a common complication of childbirth, affecting approximately 13% of women. A hormonal aetiology has long been hypothesised due to the sudden and substantial fluctuations in concentrations of steroid hormones associated with pregnancy and the immediate postpartum period. This review of two trials, involving 229 women, found synthetic progestogens do not prevent the development of postpartum depression and, due to their significant negative effect on maternal mood, their administration in the postpartum period for other clinical indications (e.g., contraception) is questionable. The prophylactic effect of natural progesterone remains unknown. Despite the promising preliminary findings, additional research is also needed before oestrogens can be recommended for the routine treatment of postpartum depression. Its role in the prevention of recurrent postpartum depression has not been rigorously evaluated. Further research is warranted.

Postpartum depression is a common complication of childbirth, affecting approximately 13% of women. A hormonal aetiology has long been hypothesised due to the sudden and substantial fluctuations in concentrations of steroid hormones associated with pregnancy and the immediate postpartum period. There is also convincing evidence that oestrogens, progestins, and related compounds have important central nervous system activity at physiological concentrations.
Задачи
The primary objective of this review was to assess the effects of oestrogens and progestins, including natural progesterone and synthetic progestogens, compared with placebo or usual antepartum, intrapartum, or postpartum care in the prevention and treatment of postpartum depression.
Методы поиска
We searched The Cochrane Pregnancy and Childbirth Group's Trials Register (March 2010), scanned secondary references and contacted experts in the field.
Критерии отбора
All published and unpublished randomised controlled trials comparing an oestrogen and progestin intervention with a placebo or usual antepartum, intrapartum, or postpartum care among pregnant women or new mothers recruited within the first year postpartum.
Сбор и анализ данных
Two review authors participated in the evaluation of methodological quality, data extraction, and data analysis. Results are presented using relative risk for categorical data and weighted mean difference for continuous data.
Основные результаты
Two trials, involving 229 women, met the selection criteria. Norethisterone enanthate, a synthetic progestogen, administered within 48 hours of delivery was associated with a significantly higher risk of developing postpartum depression. Oestrogen therapy was associated with a greater improvement in depression scores than placebo among women with severe depression.
Выводы авторов
Synthetic progestogens should be used with significant caution in the postpartum period. The role of natural progesterone in the prevention and treatment of postpartum depression has yet to be evaluated in a randomised, placebo-controlled trial. Oestrogen therapy may be of modest value for the treatment of severe postpartum depression. Its role in the prevention of recurrent postpartum depression has not been rigorously evaluated. Further research is warranted.
