Se. Hobfoll et al., DEPRESSION PREVALENCE AND INCIDENCE AMONG INNER-CITY PREGNANT AND POSTPARTUM WOMEN, Journal of consulting and clinical psychology, 63(3), 1995, pp. 445-453
A sample of 192 financially impoverished, inner-city women was assesse
d for clinical depression twice during pregnancy and once postpartum.
At the first and second antepartum interviews, respectively, 77.6% and
24.5% of the women were depressed, controlling for pregnancy-related
somatic symptoms. Postpartum depression was found among 23.4% of women
. These rates are about double those found for middle-class samples. P
articularly heightened risk for antepartum depression was found among
single women who did not have a cohabiting partner. African American a
nd European American women did not differ in rates of depression. Ante
partum depression was a weak but significant risk factor for postpartu
m depression.
