Persistent and severe postpartum depression in mothers may be associated with behavioral problems, poor mathematics grades, and a higher risk of depression in their offspring, research published Jan. 31 in JAMA Psychiatry showed.
In the study, Elena Netsi, DPhil, and her associates presented an analysis of data from 9,848 mothers and 8,287 children enrolled in the observational Avon Longitudinal Study of Parents and Children.
This analysis revealed that postpartum depression of any severity or level of persistence was associated with a two- to fourfold increase in the risk of children showing behavioral problems at age 3.5 years. In women with marked but not persistent postpartum depression, the odds ratio for child behavioral disturbance was 1.91, in mothers with severe but not persistent depression it was 2.39, and in mothers with severe persistent depression, the odds ratio was 4.84 – all of which were highly significant (P less than .001).
However, the authors reported.
It was associated with a 2.65-fold increase in the likelihood of a child having mathematics grades of D or below (P = .01), and a more than sevenfold increase in the prevalence of depression in offspring at 18 years (P less than .001). There also was a 2.3-fold increase in depression at 18 years in the children of mothers who experienced marked but not persistent postpartum depression (P = .04).
Dr. Netsi of the department of psychiatry at the University of Oxford (England) and her coauthors noted that, in women with persistent postpartum depression, mean Edinburgh Postpartum Depression Scale scores remained relatively stable, from 21 months to 11 years, suggesting an increased risk for prolonged depression.
“Identification of women with [postpartum depression] may be associated with increased treatment costs, but the overall cost to the public sector of perinatal mental health problems is five times more than the cost of improving services, further highlighting that early intervention and effective treatment of perinatal depression are a public health priority,” they wrote.
However, they acknowledged that there were mixed findings in the literature with respect to the impact on child outcomes of treating maternal depression.
“Treatments for [postpartum depression] have been relatively brief in duration and moderate in intensity; therefore, it is perhaps unsurprising that such interventions have not shown long-term benefits for either the mother or the child,” the investigators wrote.
