Estimating the Prevalence of Postpartum Anxiety and Depression in the Context of the Coronavirus Disease (COVID-19) Pandemic

Screening in these three centers is based on the use of a self-administered questionnaire for the detection of depressive disorders, the Edinburgh Postnatal Depression Scale (EPDS), which allows the calculation of a score.

In addition to the EPDS, three other tools are used at the GHPSJ maternity : a questionnaire to screen for anxiety, the State-Trait Anxiety Inventory (STAI-S), and two for trauma symptoms, the Peritraumatic Dissociative Experiences Questionnaire (PDEQ) and the Peritraumatic Distress Inventory (PDI). In this center, the screening includes a second phase with a home mailing between 6 and 8 weeks after delivery: the EPDS, the STAI-S and the Impact Events Scale-Revised (IES-R), another test screening for post-traumatic stress.

Based on the protocol implemented in these three maternity hospitals, the present research project aims to estimate the prevalence of postpartum depressive disorders at different times during and after the COVID-19 pandemic. It will also aim to identify the factors associated with the occurrence of these disorders, primarily to determine the association between elements of the pandemic context and the risk of postpartum depressive and anxiety disorders.

This project, which is based on an epidemiological approach, thus aims to assess the mental health risks associated with the COVID-19 pandemic. Postpartum women are a particularly vulnerable group, especially in terms of mental health.

Indeed, 1 to 5% develop post-traumatic stress disorder during this period and 10 to 20% develop post-partum depression. Furthermore, the National Confidential Survey on Maternal Deaths (NCSMD) shows that suicide is now the leading cause of maternal death in France (i.e., death occurring between conception and the first year following birth), before postpartum hemorrhage and before preeclampsia (data not yet published). From pooled English, Dutch, and French data, we observe that 36% of maternal deaths occurring between conception and the first year postpartum are deaths by suicide.

The COVID-19 pandemic and the associated measures that went as far as confining the population were very likely to increase the factors favouring the occurrence of mental health impairment in the general population, but perhaps even more so in certain at-risk groups such as postpartum women.

The pandemic context, whether through the fears associated with the viral infection for oneself or one's family, or through the consequences of the exceptional measures put in place in many countries to limit viral circulation, has had an effect on the general population and on the population of women in pregnancy, in different contexts. To date and to our knowledge, there is no data that would allow us to know the impact that this context may have had on the mental health of pregnant women in France. Moreover, there are no studies, either in France or elsewhere, on the impact of this pandemic context on the prevalence of psychological disorders in the postpartum period. However, this period is already a time of particular psychological vulnerability, a time when the risk of maternal suicide is at its highest. It is moreover reasonable to think that the pandemic impact and the general and local measures that accompany it may have an even greater impact during this postpartum period. The measures taken to prevent and protect against viral dissemination have had the effect of completely closing most maternity services to fathers and thus depriving mothers, totally or partially, of social and marital support and, in some situations, of physical proximity to their children, all of which are risk factors for postpartum depression.

In the perinatal context, it has also been documented that post-traumatic stress disorder is strongly associated with the risk of perinatal depression.
