We write often here about the negative effects of postpartum depression on the child. Most of the studies thus far have focused on behavior and cognitive development; a recent study from researchers at JohnsHopkinsUniversity suggests that being exposed to maternal depression during the first year of life may negatively affect the physical development of the child as well.
For women the postpartum period is a time of increased vulnerability to mood disorders. Recent estimates indicate that about 20% of women will suffer from significant depressive symptoms during the year after the birth of a child. Despite a significant push over the last decade to identify and effectively treat women with mood disorders during pregnancy and the postpartum period, treatment rates in this population remain unacceptably low. Furthermore, questions still remain regarding the optimal timing of screening and the best instruments to be used in this setting.
While postpartum depression (PPD) is typically considered to be a woman’s illness, a number of studies have suggested that, although men do not experience any of the dramatic physiologic or hormonal changes that go along with pregnancy, new fathers may also suffer from PPD. Several recent studies yield information on how to better identify new fathers at risk for depression.
The Edinburgh Postnatal Depression Scale (EPDS) was designed to screen women for postnatal depression. Cox and Holden (2003) state that the EPDS was not designed to measure anxiety. However, recent emphasis on the importance of recognizing symptoms of perinatal anxiety disorders, coupled with findings in research, have led to the suggestion that the EPDS may be used as a multidimensional tool to screen for anxiety disorders in addition to depression during the perinatal period (Matthey et al, 2012).
Women are strongly encouraged to take prenatal vitamins, and there is significant data to indicate multiple benefits to the child, including decreased risk of various congenital defects and certain types of childhood cancers. Less understood is the impact of these supplements on the mother’s mental status and her risk for mood disorder during the perinatal period. A group of researchers from Alberta, Canada has recently examined the risk for postpartum depressive symptoms in women enrolled in the Alberta Pregnancy Outcomes and Nutrition (APrON) study, specifically examining the nutrients ingested through supplements to determine whether any individual supplementary nutrients may modulate the risk of postpartum depressive symptoms.
In our weekly clinical rounds, we recently discussed how motherhood is such a unique and personal experience for each woman. Often it is assumed that this transition into a new role is easy when for many it is not. How we assess a woman's experiences during the postpartum period is often limited to just her mood. I recently came across a new self-report instrument, The Being a Mother Scale (BaM-13) developed by Stephen Matthey which attempts to assess the “wider domain of the woman’s experience of motherhood” rather than just the presence or absence of a postpartum mood disorder.
While most agree that there is a need for improved detection of anxiety and mood disorders in pregnant and postpartum women, there remain questions regarding the best instruments to use for screening. The Edinburgh Postnatal Depression Scale (a questionnaire consisting of 10 items) has long been used to screen women for postpartum depression (PPD); however, it is unclear how well these questions could be incorporated into larger surveillance programs, such as the CDC-sponsored Pregnancy Risk Assessment Monitoring System (PRAMS) which was designed to assess health behaviors and to screen for health problems, including depression and anxiety, in pregnant and postpartum women.
In our clinic, we often see women who come in for the treatment of depression and/or anxiety after the cessation of breastfeeding. Many question if breastfeeding may protect against postpartum depression and if the cessation of breastfeeding is a trigger for postpartum depression and/or anxiety. However, the research examining the association between postpartum depression and breastfeeding has been somewhat difficult to interpret.
Women who smoke during pregnancy are at greater risk for certain complications, including placental previa, placental abruption, and premature rupture of the membranes, and premature delivery. Furthermore, infants of mothers who smoke during pregnancy are more likely to be small for gestational age and are at greater risk of sudden infant death syndrome (SIDS).
In 2009, the Australian government launched the National Perinatal Depression Initiative (NPDI) in order “to improve the prevention and early detection of antenatal and postnatal depression and to provide better support and treatment for expectant and new mothers experiencing depression.” Its scope is very much like the MOTHERS Act, which became law in the United States in 2010. Both initiatives seek to increase public awareness of perinatal depression, to provide support and treatment for pregnant and postpartum women with depression, to fund research in this area, and to implement training of health care professionals.
