After the outbreak of COVID-19, people showed more negative emotions and less positive emotions, which was supported by the broaden-and-build theory(i.e., people exhibited more negative emotions for self-protection).6 The results revealed that the SAS and SDS standard scores of pregnant women during the COVID-19 outbreak were markedly higher than those of general adults (P < 0.05). It means that pregnant women are more likely to develop anxiety and depression during the outbreak. Therefore, we should pay further attention to the mental health conditions of pregnant women during the COVID-19 pandemic.
3.1 Factors influencing pregnant women’s psychological status
We found that during the COVID-19 pandemic, age, levels of education, and trimester of pregnancy were factors influencing pregnant women’s psychological status. Women who were aged 18–30 years old were at a higher risk of psychological problems than women who were aged above 30 years old. A number of scholars demonstrated that childbirth was a stressor, and all the pregnant women would show various degrees of anxiety or depression symptoms before delivery. In addition, a lower level of education was associated with a higher prevalence of anxiety and depression status,7 which is consistent with results of the present study. It is likely because people with a higher degree of education have keen self-protection awareness, and they may actively collect relevant information and knowledge of the epidemic in various ways. Therefore, they have a less cognitive bias towards the epidemic diseases and make corresponding psychological preparations in advance. The results disclosed that as gestational age increased, the risk of anxiety or depression decreased, which might be due to morning sickness and lack of pregnancy experience in early pregnancy. Additionally, the maternal immune system in early pregnancy is very sensitive, and the fetus is also in a crucial stage of organ development.8 The risks of mental illness in the middle and third trimesters may gradually reduce as gestational age and the number of production inspections increase.
3.2. Influences of COVID-19 outbreak on pregnant women
The quality of life model of depression and related disorders(Frisch, 1998, 2006) indicated a direct inverse relationship between life satisfaction and anxiety.9 Thus, if a person has always been in a low emotional state, he/she may gradually feel less hopefulness and happiness in life. The findings of the present study showed that during the COVID-19 outbreak, pregnant women with anxiety or depression tended to be more worried about the domestic epidemic. They thought that the epidemic had a great impact on their lives, and they felt that they did not prepare adequate protective supplies. Besides, the majority of pregnant women with negative emotions thought that their family members cared a little about them, and they were not ready to be a mother as well. To improve the outcome of childbirth, we should lead pregnant women actively to set up a correct concept of disease and keep a good state of mind in the face of the epidemic. For pregnant women with symptoms of anxiety or depression, they needed psychological counseling. Therefore, psychological intervention is highly essential for pregnant women with poor mental health. High levels of pregnancy-related anxiety have been found to be associated with preterm birth and low birth weight.10 Futhermore, prolonged depression during pregnancy may elevate the risks of adverse birth outcomes, including premature birth, low birth weight, and delayed development.3 These adverse outcomes indicate that a comprehensive assessment of mental health is of great significance to identify pregnant women who have anxiety or depression during the epidemic.
3.3 Measures to improve pregnant women’s psychological health
3.3.1 Popularized knowledge about COVID-19
Lessons learned from the SARS outbreak in 2003 suggest that knowledge and attitudes towards infectious diseases are associated with a level of anxiety among the population.11 Therefore, improving cognition is conducive to enhance the ability of stress response. We found that the majority of pregnant women worried to know whether their children could be born healthily and smoothly. Thus, most of pregnant women would like to acquire relevant knowledge: personal protection during pregnancy, the pregnant women’s susceptibility to COVID-19, and intrauterine transmission. Fortunately, there is no evidence of Sars-Cov-2 transmission in utero or placenta from infected pregnant women to fetuses in the global pandemic of COVID 19 at present.12 Besides, Chen et al. found no evidence of Sars-Cov-2 virus particles in pregnant products or newborns. Moreover, the clinical symptoms reported by pregnant women with confirmed COVID-19 infection are similar to those reported for non-pregnant adults with confirmed COVID-19 infection in the general population, demonstrating that the clinical process and results are more optimistic than Sars-Cov-1 infection.5
3.3.2 Provision of health care services
To avoid further spread of the epidemic, people are advised to stay at home, causing difficulty for numerous pregnant women to go to the hospitals. Although hospital visits may increase the risk of infection, the lack of medical care during pregnancy may be further detrimental. Importantly, intrauterine pregnancy and prenatal testing are significant. Statistics showed that more than 2% of pregnancies are ectopic, and congenital disabilities or genetic disorders occur in approximately 3–5% of pregnancies. Cancellation of a visit may reduce the possibility of viral infection, while sequelae may leave a greater impact.13 To solve this problem, from the survey results, we can recommend hospitals to take the following measures: (1) make appointments by schedule for production inspections, (2) provide online consultation by public account or App, (3) popularize the protection knowledge related to COVID-19 during pregnancy.
3.3.3 Relieving negative emotions
The results showed that 80.17% of pregnant women would relax themselves (i.e., listening to music, watching movies, etc.) to relieve their negative emotions, and 71.38% of pregnant women would choose to chat with their family members or friends. During the outbreak of COVID-19, residents are advised to stay at home. Hence, it is necessary to create a better family atmosphere and care more about pregnant women, which can reduce the incidence of depression and anxiety.
3.4 Limitations of the survey
We conducted a timely investigation among pregnant women during the outbreak of COVID-19. This cross-sectional study aims to reflect the psychological condition of pregnant women during the outbreak and analyze the relevant factors. There are some shortcomings in the current research. First, we conducted the survey by means of online questionnaires, which may ignore those pregnant women who do not have access to the Internet. Secondly, the limitation of the regions involved may cause information bias.
