Fear of COVID-19 in a Population of Pregnant Women in Spain … – Dove Medical Press

Introduction

The coronavirus disease pandemic of 2019 (COVID-19) became a global health emergency resulting in the need to take measures to prevent the spread of the virus such as containment, quarantine, and border closures. These measures have produced profound changes in lifestyle, and the fear of getting infected with the disease and its possible consequences at a personal, family, or social level have generated high levels of anxiety.13

Data related to the COVID-19 pandemic has been evolving since the year 2020, where SARS-CoV-2 struck the entire world. The pandemic has not only resulted in physical disturbances, but has also led to psychological, economic, and social alterations. COVID-19 develops as a result of a respiratory tract infection caused by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2).

This disease, which has affected the entire population to a greater or lesser extent, caused greater concern in certain vulnerable groups such as the elderly, the immunocompromised, or pregnant women, among others, due to previous illnesses or vital situations of special risk.4,5

COVID-19 has effects on the physical health, causing severe pneumonia, acute respiratory distress syndrome (ARDS), bacterial superinfection, cardiac alterations, shock, sepsis, thrombotic complications, pulmonary fibrosis, etc., and on mental health, especially anxiety and depression in the general population6 o it is associated with an increased risk of ICU admissions, hospitalisation,79 and although the existence of vertical transmission is extremely rare,10,11 there does appear to be evidence of an increased risk for developing pre-eclampsia, for threatened preterm birth, or low birth weight.12,13

During the pandemic, the impact this has had on the psychological health of the general population has been studied.14,15 However, there are few studies related to vulnerable population groups such as pregnant women.16,17 In addition, psychological reactions secondary to health crises seem to persist over time18 and in this sense, the presence of fear and anxiety on an ongoing basis and in the prenatal period constitutes one of the precursors of postpartum depression.1921 Although the measures taken over the last three years have been fundamental in minimising the effects of the disease, this may have had a high psychological cost for certain population groups that needs to be assessed.

Previous studies have found that public health emergencies (eg 2003 SARS-CoV) triggered a range of emotional stress responses that involved increased levels of anxiety, fear, and other negative emotions.8,22,23

Fear is defined as a response of the organism that is triggered by a situation of physical or psychological threat or danger, the purpose of which is to provide the organism with energy to overcome or counteract it by means of a response that has an obvious survival purpose.24

However, it is one of the reactions that produces the greatest number of mental, behavioural, emotional, and psychosomatic disorders.25

Fear levels in pregnancy have been studied by many researchers in the pre-pandemic period, as the pregnant woman is considered a high-risk vulnerable group compared to the non-pregnant population due to both physical and psychological changes that occur during pregnancy. According to a systematic review, the prevalence of fear during pregnancy was 14% before the pandemic,26,27 and other research correlates low and high levels of fear of birth with prolonged labour, caesarean section, increased use of epidural analgesia, and prenatal and postpartum depression or anxiety.2832

Some authors suggest that the psychological effects of uncertainty generated by health crises are more likely to persist over time,33 and that chronic fear and anxiety are precursors to psychological disorders such as depression or stress.34 These are negative emotions that are maintained over time and that, when identified as permanent in the individual, may predispose to physical illnesses and/or generate or aggravate previous mental disorders.35

On the other hand, some research has pointed to the relationship between maternal prenatal stress and anxiety levels with compromised optimal development of the hypothalamic-pituitary-adrenal axis (HPA), limbic system, and prefrontal cortex.36,37 Fear and concern about the disease affect the behaviour of individuals. Although there is no evidence of vertical transmission of SARS-CoV-2, uncertainty affects the most susceptible expectant mothers, as no one wants to be infected with a virus that presents a high risk of morbidity.38

Research on the psychological effect of the COVID-19 pandemic on pregnant women as a group of special vulnerability is still scarce in the Spanish population.23,24 Therefore, there is a need to assess levels of anxiety and fear as attitudinal factors that could be relevant in the adoption of preventive measures against new and future health threats that may require measures to restrict our freedom or health measures such as isolation or confinement.

In this context, for the assessment of the presence of fear and anxiety of COVID-19, a psychometric validation and development of the AMICO_Pregnant scale was carried out, a scale adapted and validated for specific use in the population of pregnant women in Spain. AMICO_Pregnant was designed by a panel of 10 experts using the Delphi technique and it was validated in previous studies, with a two-factor structure and 16 items that explained 78.936% of the variance. The version agreed by the panel of experts was piloted on a set of 1013 pregnant women with a mean age of 33.38 years and a standard deviation of 5.2 years, who completed a total of 978 surveys over a period of 4 months. In relation to the current pregnancy, 3.4% of the pregnant women were in the first trimester of pregnancy, 13.6% in the second one, and the majority were full-term (83%) (median=37 weeks). Over 58.8% were primigravidae and 98.7% had a singleton pregnancy. Pregnancy control was mainly low risk (52.1%).

The mean of the AMICO_Pregnant scale was 5.04 points (SD=2.36), with a range of scores from 1 to 10. The study of percentiles and quartiles allowed for a three-level relationship for the scale, ie low level with scores from 0 to 3.06, intermediate level from 3.07 to 6.53, and high level with a score above 6.54. The reliability indices measured by both Cronbachs Alpha and McDonalds Omega were 0.95 and 0.94, respectively. The bivariate analysis showed statistically significant relationships between the AMICO_Pregnant scale and some of the assessed obstetric variables.39

The aim of the study was to assess the levels of fear and anxiety of COVID-19 in the particularly vulnerable population group of women during pregnancy.

There are significant differences between the level of anxiety and fear of COVID-19 and the different categories of the studied variables.

Descriptive cross-sectional study based on questionnaires disseminated between 24 March and 26 July 2022.

The study by Gomez-Salgado et al40 developed the Anxiety and Fear of COVID-19 Assessment Scale (AMICO), based on the original 10-item version of the FCV-19 scale and incorporating 8 new items assessing the specific presence of anxiety due to COVID-19. The research confirmed a two-dimensional structure of 16 items, as well as two factors that explained 64.8% of the variance.41 The reliability study gave a total Cronbachs value of 0.92 for factor 1 (Anxiety) and of 0.90 for factor 2 (Fear). The AMICO scale has been validated in different population groups: the elderly,42 nurses,43 the general adult population,44 or the general adult population in United Kingdom.45

In this context, the scale for assessing fear and anxiety of COVID-19 in pregnant women (AMICO_Pregnant) was designed and validated in a previous study based on the Spanish version of the AMICO scale. The adaptation of AMICO to the population of pregnant women was carried out using the Delphi technique by a panel of 10 experts with an academic level of Doctor or Official Masters Degree and whose areas of knowledge were obstetrics, public health, or psychology; one of the experts was also pregnant at 28 weeks of gestation.

Exploratory factor analysis obtained a two-dimensional structure of 16 items (anxiety and fear) that could explain 78.935% of the variance (KMO test=0.962; Bartlett's test X2=19,100.292; p<0.000).

The reliability study was carried out with both Cronbachs Alpha and McDonalds Omega coefficient estimates, giving values of 0.95 and 0.94, respectively.

The questionnaire contains 16 items with a Likert-type response scale from 1 to 10, where 1 expresses a very low level of fear and anxiety and 10 a very high level. The total score of the scale is obtained by calculating the mean score from the self-reported responses, and the value ranges from 1 to 10 points. A mean total score 3.06 indicates a low level of fear and anxiety; a mean total score between 3.07 and 6.53 is indicative of intermediate levels of fear and anxiety; and a mean total score 6.54 would suggest a clinically relevant level of fear and anxiety. The MannWhitney U statistic confirmed the significant differences between the different levels, with values of p=0.001.39

The number of births registered in Spain during 2021 amounted to 337,380 births.46 The required sample size was calculated considering a confidence level of 95%, for a maximum sampling error of 5%, and it amounted to 385 participants.47 A probabilistic snowball sampling was carried out. The research team carried out a process of identification of professional associations and health centres which were asked to collaborate in the dissemination, guaranteeing the confidentiality of the data. However, the final sample obtained was 978 pregnant women.

Sociodemographic variables included age, place of residence, marital and cohabitation status, level of education, occupation and employment sector, personal history, obstetric history, relationship with the disease, feeling of danger, and vaccination status against COVID-19.

Finally, the last section of the questionnaire included the AMICO_Pregnant scale with the aim of measuring fear and anxiety of COVID-19 disease. The final survey consisted of a total of 33 items.

The data collection tool was designed using the GoogleFoms software. The questionnaire was disseminated by mass mailing to residents throughout Spain by a free national magazine with content and newsletters related to pregnancy and childcare (Mi Beb y Yo), and a link and QR code redirecting to the aforementioned GoogleForms form was distributed to subscribers who had agreed to participate in the research.

In turn, different organisations related to perinatal care, professional associations, obstetrics and gynaecology nurse training centres, primary care centres, as well as public and private hospitals in the national territory also collaborated in the dissemination of the survey. The researchers contacted the different organisations that were asked to collaborate in the dissemination. Some professionals belonging to the different contacted organisations collaborated in the dissemination of the questionnaire when the pregnant woman went to her prenatal check-up. The nurse specialist in obstetrics and gynaecology offered her the possibility to participate in the study by means of a QR code that redirected her to the online questionnaire.

Once the respondent accessed the form, information was displayed on the legal conditions, consent, and confidentiality of data, which they had to accept in order to access the questionnaire; the form also included a contact e-mail address to provide a reference for consultation and exercise of rights and duties in terms of data confidentiality, and to make enquiries about the study.

Univariate and bivariate data analysis was performed using the Statistical Program for Social Sciences (SPSS) version 28.0 package. First, an analysis of the normality of the distribution of the AMICO_Pregnant score data was performed by calculating the KolmogorovSmirnov test, showing a significance level of p=0.000, which indicated an absence of normality.

For the bivariate analysis, different non-parametric tests were used based on the specific characteristics of the variables studied: Wilcoxon signed-rank test, KruskalWallis test, Mann-Whitney U-test, and Spearmans Rho, also estimated to analyse the correlation between two quantitative variables.

The study was conducted in accordance with the Declaration of Helsinki 2013 by the World Medical Association and the European Unions Good Clinical Practice Directive (Directive 2005/28/EC). The research protocol was presented and approved by the Biomedical Research Ethics Committee of the province. The research protocol was also approved.48 All participants were informed about the procedure and objectives of the study, and they gave their informed consent prior to the start of data collection.

The questionnaire was answered by a total of 1013 pregnant women over 18 years of age and with a mean age of 33.38 years (SD=5.28). Of the total sample, 35 (3.5%) women completed the questionnaire partially, resulting in a complete sample of 978. 3.4% were in the first trimester of pregnancy, 13.6% in the second trimester, and 83% in the third trimester (M=37; SD=3.44). 30% were recruited at the antenatal clinic of the University Regional Hospital of Malaga, Maternity Hospital.

Responses were also obtained from all the Spanish provinces. 60.9% of the responses were from the province of Malaga, being the province with the highest response rate, followed by 5.7% from Madrid and 4.1% from Barcelona. The provinces of Seville and Valencia had participation rates between 3% and 5%. The rest of the 47 provinces in Spain showed a participation rate of less than 3% (Table 1).

Table 1 Description of the Sample

In terms of marital status, 89.1% declared themselves to be in a relationship and only 10.9% were single; 47.5% said they were married, 41.1% were in a stable relationship, and 10.4%, 0.7%, and 0.4% said they were single, divorced or widowed, respectively. In relation to the employment sector, 33.6% belonged to the service sector, 22.8% to auxiliary, technological, or financial activities, 20.8% to the health sector, 13.9% to education, and the remaining 6.9% were engaged in other activities. 2% were unemployed.

The highest level of education was university (35.3%), followed by upper secondary school or vocational training (28.7%), and Masters degree or doctorate (16.1%). Primary and secondary studies were reported by 3.4% and 15.7%, respectively, and only 0.8% had no studies.

Obstetric history showed a representative sample in terms of nulliparity or multiparity, with 58.8% being pregnant for the first time and 41.2% having been pregnant two or more times. 98.7% were singleton pregnancies and 68.7% were spontaneous conception and wanted pregnancies. Personal history showed 73.8% of pregnant women with no history of clinical interest and the main complaints were respiratory diseases, bronchial asthma, or previous pneumonia in 7.4%, followed by autoimmune diseases in 4.2% or coagulation problems in 3.1%.

In relation to contact with COVID-19 disease, 48.7% of the pregnant women had had contact with the disease, 9.1% stated that a member of their family had had contact with COVID-19, and the remaining 42.3% stated that they had not had contact with the disease or only outside their family circle. In this regard, 93.9% reported having received at least one dose of the COVID-19 vaccine. In relation to the influence of the disease on their birth plans, 19.6% acknowledged having suffered changes in their birth plans due to the pandemic situation.

In relation to the self-perception of the pandemic danger situation with respect to the previous year (2020) in a range of 1 to 10, the mean was 4.89 points (SD=2.07), and in relation to the self-perception of the levels of fear and anxiety with respect to the previous year, in a range of 1 to 10 the mean was 4.75 points (SD=2.49).

The mean of the AMICO_Pregnant scale was 5.04 points (SD=2.36). The bivariate analysis showed statistically significant differences in the mean score of the scale and the following variables: weeks of gestation, contact with the disease, vaccination schedule, and changes in the birth plan (Table 1). Pregnant women with pregnancies closer to term showed lower levels of fear and anxiety than those at lower gestational weeks (37 wk; =5.04 p=0.000). In addition, pregnant women who had experienced the disease showed lower levels of fear and anxiety (=4.66) than those who had not had contact with the disease (=5.22) or the contact had been outside their family circle (=5.23). On the other hand, pregnant women who had received any dose of the COVID-19 vaccine showed similar levels of fear and anxiety, with no significant differences between the number of doses received (1 dose=5.26; 2 doses=4.90; 3 doses=5.11). However, those who had not received any doses showed significantly lower levels (=3.09 sig.=0.000). In relation to changes in their birth plan, pregnant women who had not experienced changes in their birth plan or who had no birth or delivery plan showed lower levels of fear and anxiety (=4.33) than those whose birth plans had been modified (=6.04).

The bivariate analysis of the correlation between quantitative variables showed statistically significant results. On the one hand, between the levels of fear and anxiety according to the AMICO_Pregnant scale and the self-perception of the level of danger of the pandemic situation with that of a year earlier using the Tau B correlation coefficient (0.556 p=0.000), ie, pregnant women who reported a low level of danger showed lower levels of fear and anxiety. On the other hand, self-reported levels of fear and anxiety in relation to the pandemic situation one year earlier showed a strong relationship with levels of fear and anxiety assessed with the AMICO_Pregnant scale according to the Tau B correlation coefficient (0.727 p=0.000), ie pregnant women who self-reported a decrease in levels of fear and anxiety compared to one year earlier showed lower levels of fear and anxiety on the scale. Finally, there was no significance between anxiety and fear levels and the age of the pregnant woman.

A categorical regression analysis was performed with the mean total score of the AMICO_Pregnant scale as the dependent variable and the categorical variables that had shown significant differences in the bivariate analysis, showing an adequate adjustment; 28% of the variance of the data was explained by this regression model, which made it possible to identify the variables that predicted high levels of fear and anxiety: administered vaccinations, contact with COVID-19 patients, and changes in the birth plan obtained p-values <0.05 (Table 2).

Table 2 Categorical Regression Model

In this sense, the results showed that women who had received only one dose of vaccination had higher levels of fear and anxiety compared to those who had received a complete vaccination or even those who had not received any dose. Pregnant women who had not had contact with the disease within the family had higher levels of fear and anxiety, and finally, the existence of a birth plan that had undergone changes or the absence of any birth or delivery planning were shown to be events that increased the levels of fear and anxiety in pregnant women.

This study attempts to indicate the effect that the COVID-19 pandemic has had on the levels of fear and anxiety in pregnant women as mediators of psychological well-being. This situation of special vulnerability with the presence of specific expectations and attitudes may have an impact on the ongoing pregnancy or become a determinant of the psycho-affective perception of the pregnant woman. However, when it comes to mental health in relation to the pandemic, it is difficult to find research that focuses exclusively on pregnant women despite being a particularly vulnerable group. Some authors have reported moderate levels of fear of the disease in pregnant women one year after the start of the pandemic.17

Fear during pregnancy may represent a relevant risk factor in the normal development of the current pregnancy; some authors point out an incidence between 45% and 77%.2,49,50 In this regard, there is research on the consequences that fear can have on infant psychophysiological development.23 Moreover, anxiety is an additional risk factor that intervenes in neonatal development in a number of ways.37,5153

This research has shown the multiple circumstances that can have an impact on the levels of fear and anxiety of women with a pregnancy in progress, becoming determinants of their state of mind.

More specifically, the findings show that pregnant women show an intermediate level of fear and anxiety, in agreement with research carried out two years earlier, such as that by

Allande-Cuss et al,54 which assessed levels of fear and anxiety in the general population in Spain at the start of the pandemic, showing a psychological impact considered moderate. However, the work by Morgado-Toscano et al45 in the UK general population showed lower levels of psychological impact during the months of April to June 2021 in relation to both the studies by Allande-Cuss et al35 and the findings of the present study.

The results may have been influenced by several factors: first, the timing of data collection and the pandemic situation; during the data collection period of this research, vaccination coverage in Spain was above 92% in the population over 12 years of age, more than 92% of those over 60 years of age had received a booster dose, and the main indicators for monitoring the pandemic were at a low risk level in most parts of Spain.28

On the other hand, sex, especially if we compare a female-only population group with a group of both sexes, should be taken into account. It seems to be a determinant in the levels of fear and anxiety, and it may have contributed to intermediate levels despite the low risk situation of the pandemic at the time. Indeed, different studies have always shown higher levels in women compared to men.29

Uncertainty in relation to pregnancy or delivery plans, clinical variability, uncertainty in relation to contagiousness in their environment, the lack of a complete vaccination schedule and, consequently, uncertainty in relation to the disease and its effects on both mother and newborn have shown to be factors underlying these increases in the levels of fear and anxiety in pregnant women during the pandemic, according to the data collected. The group of women who had not been infected with COVID-19 showed higher levels of fear and anxiety when compared to the group of women who had been infected with COVD-19 or whose contact with the disease was limited to outside their family circle. These results support the data obtained in other research on the general population or on vulnerable population groups such as the elderly.42,54

A closer examination of the findings and conclusions of the authors cited above suggests that the uncertainty caused by an unexpected circumstance considered a threat to health, in this case a pandemic situation, can generate emotions of fear and anxiety in pregnant women5557 as they do not know how to deal with a circumstance that alters their expectations and doubt their ability to adapt to the new circumstance, thus producing fear and mistrust towards the near future.58 On the other hand, the findings of this research in relation to the variables related to individual health do not show significant differences in the evaluation of the levels of fear and anxiety in relation to personal history, type of conception, type of prenatal control, number of embryos or number of previous pregnancies. In this sense, in agreement with other research, despite the situation of special vulnerability on a physiological level due to the changes that pregnancy produces in the woman and despite the fact that the health of the woman is fundamental for a state of well-being of the foetus, the woman prioritises the health of the pregnancy or of the baby over her own; this is a psychological approach linked to an innate attitude of protection of the offspring.27,37,59 However, the pandemic situation may have exacerbated this protective attitude and generated a response by increasing levels of fear and anxiety in women.33 In addition, multiparity has been considered by some authors as a protective factor against levels of anxiety and fear in relation to pregnancy or childbirth,34 probably due to the experience of having had a previous birth. However, the findings do not show significant differences between primigravidae and multigestation, which may be explained by the specificity of the questions asked in the data collection on fear and anxiety related to COVID-19 disease.

In relation to age or marital support as influential factors in the levels of fear and anxiety, the descriptive analysis used in the interpretation of the data shows a homogeneous sample in terms of age, which justifies the absence of significant differences, and on the other hand, a sample with 89.1% in a couple situation justifies the absence of significant differences in this sense.

In addition, social variables such as employment sector or level of education might have been particularly affected by the timing of the research, which was carried out with hardly any employment restrictions, which would justify the absence of significant differences.

Finally, pregnant womens perceptions of danger may vary depending on multiple factors such as the information they receive, their experiences within their family circle, their social or work environment, and the way they feel about their pregnancy.23,49 Although the pandemic has brought about changes in lifestyle, in relationships with others, or with the healthcare system,60 when analysing the results obtained in this study, pregnant women who understood the pandemic situation to be better than in the past, which may suggest that they had adapted to living with the new normality, showed greater emotional resilience in the face of the present situation, reporting lower levels of fear and anxiety.

Therefore, the findings are consistent with current thinking on the emotional consequences of a pandemic.1,2,49,50,61 The pregnant woman, at first, tends to show negative feelings about the potential threat posed by the pandemic during pregnancy, with positive emotions emerging secondary to circumstances such as the vaccination schedule, weeks of gestation, maintenance of her birth plans, or previous experiences with the disease. This evolves into a state of ambiguity that is common in pregnant women due to feelings of vulnerability against which they do not feel prepared, but nevertheless, they face the threat thanks to their coping mechanisms and the support of their social circle.

Regarding the limitations of this research, it should be noted that 60.9% of the sample was collected from the city of Malaga. However, this province constitutes 3.6% of the countrys population and the sample collection process was not probabilistic. On the other hand, a high proportion of educated women participated, which is common in research, as educated women are the ones who participate the most in research.35 In this sense, therefore, the results obtained are not entirely extrapolable to the entire Spanish population despite the sample size, and besides, the pandemic situation has evolved differently in each geographical area. Another limitation is that none of the participants informed of mental health disorders, which may be attributed to the participants fear of reporting them.

Furthermore, the results obtained are in the context of the COVID-19 disease. However, despite the above limitations, the research has generated interesting results for the nursing clinical practice that may be applied in the context of other respiratory infectious diseases affecting a particularly vulnerable group such as pregnant women, as well as for the scientific community interested in the field of mental health.

The results of this research show certain characteristics of pregnant women who, despite a pandemic situation in a state of remission, reported intermediate levels of fear and anxiety. Pregnant women who were close to term, without previous close contact with the disease, without a complete vaccination schedule, and who had undergone changes in their pregnancy or birth expectations were more likely to report negative experiences in terms of levels of fear and anxiety. Given the potential consequences of untreated high levels of fear and anxiety during gestation,32,57,62 identifying women who are more immersed in their expectations of pregnancy and childbirth by working proactively to help manage greater flexibility towards the different deviations that may occur in pregnancy and childbirth can help moderate fear and anxiety if pregnancy and childbirth do not proceed according to their expectations. Mental health prevention and treatment in the antenatal period helps to mitigate the effects of high levels of fear and anxiety at a time of particular mental health vulnerability.

This research has not received any public or private funding.
