The global epidemic crisis is having a profound effect on all aspects of our life. In Poland, as well as in other European countries self-isolation and severe restriction in everyday routine were introduced in early March 2020. A study carried out in Poland 10 days after introducing restrictions [1] showed that the level of anxiety in Polish society was quite high e.g. 75% of the respondents were worried that some people would not follow the government’s instructions and the virus would spread too quickly, 73% were afraid of hospital overcrowding and healthcare system failure, 72% - losing loved ones, 71% - financial crisis and market collapse, and 70% - panic and irrational behaviour of other people. Moreover, 26% of Poles estimated that their anxiety reached the level of a panic attack. The study [1] also revealed that women felt greater fear in comparison to men at the beginning of the epidemic crisis.
According to international studies [2,3], especially vulnerable to stress and mental health problems are a front-line health and social care staff, those with pre-existing health issues, young people (aged ≤18 years), and older adults (aged ≥65 years). However, beyond direct influence, the psychological and social effects of the COVID-19 epidemic are increasingly seen as pervasive factors that may affect mental health now and in the future [2]. Based on the studies concerning the early phase of the severe acute respiratory syndrome (SARS) outbreak, a range of psychiatric morbidities may be suspected including persistent depression, anxiety, panic attacks, psychomotor excitement, psychotic symptoms, delirium, and even suicidality [4-6]. Moreover, we believe that the COVID-19 epidemic crisis along with a high level of anxiety [1] could contribute to the intensification (or be a trigger) of mental health problems among those people who were at high-risk under normal (non-epidemic) conditions [7,8]. We assumed that such factors as anxiety about the possibility of infection during pregnancy and/or after delivery, restrictions on delivery and hospital stay (limited contact with relatives and friends), limited access to specialist and control treatment (often restricted only to emergencies), a radical change in the postpartum care: midwife-woman relationship, where often the comforting presence, practical help in breastfeeding as the key supportive elements, has been transferred “online” in an attempt to maintain distance and reduce cross-infection, loss of social support due to voluntary quarantine and lockdown, confusion and panic (often increased by fake news) – all may affect the well-being and mental health of mothers in the postpartum. The existing psychosocial resources may not be sufficient to cope with the process of transition to motherhood. It is worth emphasizing that lack of social support is listed as one of the major risk factors for postpartum depression along with high life stress, current or past abuse, prenatal depression, and marital or partner dissatisfaction [8].
Previous studies [9,10] described the effects of the COVID-19 epidemic on the depression and anxiety levels of pregnant women. A recent assessment of depression symptoms with the Edinburgh Postnatal Depression Scale revealed significantly higher rates of depressive symptoms among pregnant women assessed after the declaration of COVID-19 epidemic in comparison to women assessed in pre-epidemic period [10]. However, there are no reports on the occurrence of severe depressive symptoms among women in the postpartum period during an epidemic crisis.
Postpartum depression (PPD) is a common and serious mental health problem that affects about 13-20% of new mothers [11,12]. In many cases PPD resolves spontaneously e.g. Whiteford et al. [13] reported the remission rate of 53% in adult samples experiencing depression within one year and O'Hara et al. [14] indicated that the symptoms last seven months on average when left untreated. Yet still, about one in three women feel worse even more than a year after delivery, and research [15,16] indicate that there are about 40% cases of relapses. Researchers [17-19] indicate that suicide accounts for one in five deaths and is the second leading cause of mortality in the first year postpartum. Therefore, screening procedures (to detect PPD symptoms) are widely implemented in many countries. Of course, screening test precedes the extended clinical examination but helps to quickly detect cases that may require fast professional help [20].
The severity of PPD symptoms is associated with many biological and non-biological factors e.g. Wisner et al. [19] indicate that the particular risk refers to those women with a personal or family history of depression, physical or sexual abuse, unplanned pregnancy, and pregnancy complications. There are also additional social factors that may influence depressive symptoms: for example, research indicates that shorter maternity leave is associated with greater depressive symptoms at 9 months postpartum [21, 22].
On the other hand, social support is an important protective factor [23]. However now, during the COVID-19 pandemic, new mothers are deprived of their social network. According to the British Academy of Medical Science, major adverse consequences of the epidemic crisis are increased social isolation and loneliness [24], which are strongly associated with anxiety, depression, self-harm, and suicide attempts across the lifespan [25, 26]. The aggravated depressive symptoms during the global epidemic crisis can thus be caused directly - by concerns about exposure to COVID-19 (an additional strong and widespread stressor) but also indirectly. Apart from the negative consequences of isolation, what was already mentioned, many families also encounter several changes in financial well-being and economic stability. Moreover, prolonged direct contact with other children (daily care and home education during a pandemic), change to home office for working mothers can intensify daily fatigue and stress, make work-life balance more difficult, trigger conflicts and interfere with adapting to life with a new baby. So, an epidemic crisis can limit a great part of the psychological resources that builds woman’s health in the postpartum period.
