Emerging risk factors ID'd for postpartum depression
Gabriel D. Shapiro, M.P.H., from the University of Montreal, and colleagues reviewed the literature and identified 75 studies related to postpartum depression, nutrition, n-3 PUFAs, and 5-HTT genotype.
The researchers found that associations between the 5-HTT genotype and postpartum depression were reported in three studies. Accumulating evidence suggests that n-3 PUFA intake correlates with the risk of postpartum depression. Preliminary evidence is suggestive of an interaction between these risk factors.
"Because it can be reasonably hypothesized that the 5-HTT genotype and n-3 PUFAs impact on the risk of postpartum depression, in part through the same mechanism, studying them jointly would present an opportunity to advance our understanding of how genetic and dietary exposures may interact in the etiology of postpartum depression," the authors write. "Knowledge garnered from this effort has the potential to improve the prediction, prevention, and treatment of this significant public health problem."
