Ka. Yonkers et al., Onset and persistence of postpartum depression in an inner-city maternal health clinic system, AM J PSYCHI, 158(11), 2001, pp. 1856-1863
Objective: Postpartum depressive disorders lead to maternal disability and
disturbed mother-infant relationships, but information regarding the rates
of major depressive disorder in minority women is noticeably lacking. The g
oal of this study was to determine whether the risk factors for and rate of
postpartum major depressive disorder in a predominantly African American a
nd Hispanic clinic population would be similar to those reported for Caucas
ian women.
Method: Investigators systematically screened all women scheduled for their
first postpartum visit on selected days at four publicly funded inner-city
community maternal health clinics in Dallas County (N=802). A multistage s
creening process included the Edinburgh Postnatal Depression Scale, the Inv
entory of Depressive Symptomatology, and the Structured Clinical Interview
for DSM-IV for a maximum of three assessments during the initial 3-5-week p
ostpartum period.
Results: The estimated rate of major depressive disorder during the postpar
tum period among women in this setting was between 6.5% and 8.5%. Only 50%
of the depressed women reported onset following birth. Bottle-feeding and n
ot living with one's spouse or significant other were associated with depre
ssion at the first evaluation; persistent depressive symptoms were linked w
ith the presence of other young children at home. Greater severity of depre
ssive symptoms at first contact predicted major depressive disorder several
weeks later.
Conclusions: Rates of postpartum depression among Latina and African Americ
an postpartum women are similar to epidemiologic rates for Caucasian postpa
rtum and nonpostpartum women. As previously shown for Caucasian women, majo
r depressive disorder in many Latina and African American postpartum women
begins before delivery, revealing the need to screen pregnant women for dep
ression.
