Does postnatal depression increase risk of antenatel depression next time?

Embargoed until Tuesday, June 29, 2004

Approximately 10% of women experience psychological distress with significant depressive symptoms during pregnancy. Those with histories of major depression appear to be at higher risk of the depression recurring during pregnancy.

 

This study set out to compare subsequent pregnancy outcome in women with histories of postnatal depression who were attending a Tertiary Obstetric Unit (TOU) and a District General Hospital (DGH) in Northern Ireland.
 
Women were traced on a special computer system between January 2001 and May 2002. Those with a previous history of postnatal depression recorded at ‘booking’ for their current pregnancy were studied. Age, number of previous children, drug history, follow-up and subsequent antenatal depression were noted.
 
It was found that 6.6% of women attending the TOU had a history of postnatal depression, compared with 4.7% in the DGH. The most common age range was 31-35 years at both centres.
 
The DGH group had the most children. 70% of patients in the TOU and 80.6% in the DGH required treatment. The antidepressant fluoxetine was the most commonly prescribed drug in each centre.
 
Other therapy included vitamin B6, oestrogen patches, St. John’s Wort and acupuncture. 1.3% of women in the TOU and 3.5% in the DGH were referred to a psychiatrist.
 
During the subsequent pregnancy, 4.3% of women in the TOU and 4.4% in the DGH remained on antidepressants. Again fluoxetine was the most commonly prescribed medication. One woman in each centre took an overdose during this pregnancy.
 
The authors of the study comment that percentages and ages of women were similar at both centres. The number of previous children differed between the centres, and this was geographically specific to larger families in the more rural setting.
 
More women in the DGH required treatment, which may be why more of them attended a psychiatrist. Other therapies are still being used, even though their effectiveness is questionable
