Comparative Incidence of Depression in Women and Men, During Pregnancy and after Childbirth

Abstract
Background: Comparing women's and men's emotional reactions to childbirth can clarify the impact on mental health of childbirth as a life event.Method: Fifty-four first-time mothers attending obstetric services in Oporto, Portugal, and 42 of their husbands or partners participated in a longitudinal study of their mental health. All subjects were given a semi-structured clinical interview (SADS) at 6 months antenatally and at 12 months postnatally and sub-samples were interviewed at 3 months postnatally. At all these times all the mothers and fathers also completed a translated version of a self-rating scale for depression, the Edinburgh Postnatal Depression Scale (EPDS).Results: More women than men had past histories of depression but their rates of depression did not differ significantly during pregnancy. In the first 3 months postnatally, nearly a quarter of the women ‘at risk’ were found to have become depressed (major, minor and intermittent) in contrast with less than 5% of the men. In the next nine months men were more prone to become depressed than previously and their conditions tended to follow an earlier onset of depression in their spouses.Conclusion: Comparisons of EPDS and SADS ratings showed that the translated EPDS was a valid instrument for women but it was less satisfactory when applied to men.
