Duke: A long-term study of mother-child pairs in Pakistan has found that
the children turn out pretty much the same, whether or not their mothers
received treatment for depression during pregnancy. An earlier
study of the same population found that the mothers themselves benefited
from the treatment, with less depression, and demonstrating related
healthy behaviors with their newborns, such as breastfeeding. But those
improvements were short-lived.
The “Thinking Healthy Programme” is
a successful depression intervention evaluated through a randomized
trial among a group of pregnant women seven years ago. A reference group
of pregnant women who did not suffer from depression were added in the
current study.
Researchers looked specifically at the women’s
now-7-year-old children. Perinatal depression has been linked to
negative child development outcomes by past studies; this is the first
large scale study of a maternal depression intervention from a low- or
middle-income country to provide additional evidence of this connection.
The
treatment didn’t improve the children’s outcomes and all children of
depressed moms had worse outcomes on emotional and behavioral measures
relative to children whose moms did not have prenatal depression. The
cognitive and physical outcomes did not differ between the two groups.
“The
findings are significant because they suggest that treatment for
depression in the perinatal period, even if successful, is not enough to
improve a child’s developmental trajectory,” said Joanna Maselko,
professor of global health at Duke University, and the study’s lead
author.
“Maternal depression affects child development -- which we
have seen previously and which this study reinforces -- and efforts to
diminish its effects should be an integral part of maternal and child
health programs,” she said.
The findings will be published in the
June 3, 2015 edition of The Lancet Psychiatry
(http://www.thelancet.com/journals/lanpsy/article/PIIS2215-0366(15)00109-1/abstract).
This
research is funded through the Saving Brains Programme of Grand
Challenges Canada, which is funded by the government of Canada. (http://www.grandchallenges.ca/).
The program supports bold ideas to promote healthy brain development in
the first 1000 days with lasting impact on human capital in low-and
middle-income countries, so children and societies can reach their full
potential.
In addition to Duke’s Maselko, the team included
researchers from the Human Development Research Foundation in Pakistan,
and University of Liverpool and University of Essex, both in the United
Kingdom.
