Prevalence of anxiety and depression among pregnant women during the COVID-19 pandemic: a meta-analysis

Timing of selective serotonin reuptake inhibitor use and risk for preterm birth and related adverse events: with a consideration of the COVID-19 pandemic period

OBJECTIVE

There is uncertainty around the safety of SSRIs for treating depression during pregnancy. Nevertheless, the use of SSRIs has been gradually increasing, especially during the COVID-19 pandemic period. We aimed to (1) characterize maternal depression rate and use of SSRIs in a recent 10-year period, (2) address confounding by indication, as well as socioeconomic and environmental factors, and (3) evaluate associations of the timing of SSRI exposure in pregnancy with risk for preterm birth (PTB), low birthweight (LBW), and small for gestational age (SGA) infants among women with depression before pregnancy.

METHODS

We conducted propensity score-adjusted regression to calculate odds ratios (ORs) of PTB, LBW, and SGA. We accounted for maternal/pregnancy characteristics, comorbidity, depression severity, time of delivery, social vulnerability, and rural residence.

RESULTS

There were 50.3% and 40.3% increases in the prevalence rate of prenatal depression and prenatal SSRI prescription rate during the pandemic. We identified women with depression ≤180 days before pregnancy (n = 8406). Women with no SSRI order during pregnancy (n = 3760) constituted the unexposed group. The late SSRI exposure group consisted of women with an SSRI order after the first trimester (n = 3759). The early-only SSRI exposure group consisted of women with SSRI orders only in the first trimester (n = 887). The late SSRI exposure group had an increased risk of PTB of OR = 1.5 ([1.2,1.8]) and LBW of OR = 1.5 ([1.2,2.0]), relative to the unexposed group. Associations between late SSRI exposure and risk of PTB/LBW were similar among a subsample of patients who delivered during the pandemic.

CONCLUSIONS

These findings suggest an association between PTB/LBW and SSRI exposure is dependent on exposure timing during pregnancy. Small for gestational age is not associated with SSRI exposure.

Sleeping for two: A randomized controlled trial of cognitive behavioural therapy for insomnia (CBTI) delivered in pregnancy and secondary impacts on symptoms of postpartum depression

BACKGROUND

Insomnia in pregnancy is common and highly comorbid with depression.

OBJECTIVE

To investigate if: 1) depressive symptoms decrease after cognitive behavioural therapy for insomnia (CBTI) delivered in pregnancy, and 2) changes in insomnia symptoms represent a mechanism linking CBT-I treatment and reduced symptoms of postpartum depression.

METHODS

A two-arm, single-blind, parallel groups randomized controlled trial (RCT) design was used to evaluate the impact of a 5-week CBT-I intervention adapted for pregnant people with insomnia (N = 62). Participants were eligible if they were pregnant, between 12 and 28 weeks gestation, and met diagnostic criteria for insomnia. Participants completed questionnaires assessing symptoms of insomnia and depression pre-intervention (T1), post-intervention (T2), and six months postpartum (T3). A path analysis model was used to test direct and indirect effects simultaneously.

RESULTS

There was a significant direct effect of CBT-I on postpartum depressive symptoms at T3. Additionally, significant indirect treatment effects on depressive symptoms at T3 emerged, through depressive symptoms at T2 and through improvements in insomnia that persisted from T2 to T3.

LIMITATIONS

Limitations to the current study include limited generalizability, the non-depressed sample, and variability in treatment and assessment delivery (in-person vs. online).

CONCLUSIONS

CBT-I treatment in pregnancy may indirectly reduce postpartum depressive symptoms, through sustained improvements in insomnia symptoms.

Are social determinants associated with depression among married women of reproductive age? A mixed methods study from urban slums of Islamabad, Pakistan

Depression among married women of reproductive age is on the rise in Pakistan, owing to post-COVID-19 phase, super-inflation, increasing poverty, deteriorating law and order situation and perpetuating the uncertain political situation in the country. This study aimed to investigate the factors associated with depression among married women of reproductive age in Pakistan, using a mixed methods approach. The quantitative phase utilized the Urdu version of the Patient Health Questionnaire-9 (PHQ-9) to assess depression among 340 married women. Twelve women with higher scores on the PHQ-9 were selected for in-depth interviews in the qualitative phase. The quantitative analysis revealed a higher prevalence of depression among women with poor socioeconomic status, lower educational levels, larger family sizes, and recent deaths in the family. In the qualitative phase, the main themes identified were the impact of social conditions, such as societal expectations and gender roles, the influence of medical conditions on mental health, financial difficulties, the stress associated with caring for a larger number of children, and the emotional burden of recent deaths in the family. This study highlights the importance of addressing depression among married women of reproductive age in Pakistan. It is crucial to focus on early diagnosis and prompt treatment to mitigate the adverse effects of depression on the affected individuals and their families. Targeted interventions should consider the social determinants of depression, including improving socioeconomic conditions through safety nets, providing mental health support at the primary health care level, and addressing the specific health issues and needs of women in the reproductive age group. A multi-pronged approach and health system's thinking can reduce the burden of depression among women, ultimately enhancing their overall well-being, productivity and quality of life.

Social support buffers the impact of pregnancy stress on perceptions of parent-infant closeness during the COVID-19 pandemic

Pregnant individuals and parents have experienced elevated mental health problems and stress during COVID-19. Stress during pregnancy can be harmful to the fetus and detrimental to the parent-child relationship. However, social support is known to act as a protective factor, buffering against the adverse effects of stress. The present study examined whether (1) prenatal stress during COVID-19 was associated with parent-infant closeness at 6 months postpartum, and (2) social support moderated the effect of prenatal stress on the parent-infant relationship. In total, 181 participants completed questionnaires during pregnancy and at 6 months postpartum. A hierarchical linear regression analysis was conducted to assess whether social support moderated the effect of stress during pregnancy on parent-infant closeness at 6 months postpartum. Results indicated a significant interaction between prenatal stress and social support on parents' perceptions of closeness with their infants at 6 months postpartum (β = .805, p = .029); parents who experienced high prenatal stress with high social support reported greater parent-infant closeness, compared to those who reported high levels of stress and low social support. Findings underscore the importance of social support in protecting the parent-infant relationship, particularly in times of high stress, such as during the COVID-19 pandemic.

Prevalence of and relevant factors for depression and anxiety symptoms among pregnant women on the eastern seaboard of China in the post-COVID-19 era: a cross-sectional study

BACKGROUND

Antenatal depression and anxiety symptoms may have negative consequences for both mothers and offspring, and upward trends in the prevalence of these symptoms were especially apparent during the COVID-19 epidemic. The purpose of this study was to evaluate the prevalence of and relevant factors influencing depressive and anxiety symptoms in Chinese pregnant women in the post-COVID-19 era.

METHODS

We conducted an online survey of 1,963 pregnant women in Jiangsu Province, using a cross-sectional design, and collected their general demographic data. The nine-item Patient Health Questionnaire 9 (PHQ-9) was used to evaluate depression symptoms, and the seven-item Generalized Anxiety Disorder 7 (GAD-7) was used to measure anxiety symptoms.

RESULTS

The prevalence of reported antenatal depressive symptoms, anxiety symptoms, and depression combined with anxiety symptoms was 25.2%, 27.9%, and 18.6%, respectively. Of the respondents, the prevalence of moderate to severe depression, and anxiety was 7.9% and 7.7%, respectively. Binary logistic regression analysis demonstrated that age, low level of education, rural area, unemployment, pregnancy complications, poor marital relationship, and fair household income were positively association with both depressive and anxiety symptoms (all P < 0.05). The proportion of women reporting anxiety symptoms in the third trimester was 1.91-fold higher than in first trimester. Parity was a relevant factor for depression and anxiety symptoms (all P < 0.05).

CONCLUSIONS

In the post-COVID-19 era, the prevalence of depression and anxiety symptoms in pregnant women was higher than expected, and it is vital to establish hospital, community, and family psychological health screening systems based on relevant factors and enhance early preventive measures.

Disruptions in Lifestyle Habits and Access to Social Support in the Time of COVID-19: Associations With Diabetes Distress and Depression Among Adults With Type 1 Diabetes Living in British Columbia

OBJECTIVES

In this study, we examined rates of diabetes distress and depressive symptoms in adults with type 1 diabetes (T1D) during the COVID-19 lockdown and its association with disruptions in lifestyle habits and access to social support.

METHODS

This cross-sectional investigation included a convenience sample of 60 adults with T1D who completed a survey assessing diabetes distress (Type 1 Diabetes Distress Scale), depressive symptoms (Personal Health Questionnaire-9), and disruptions in lifestyle habits (sleep patterns, dietary patterns, exercise routine) and access to support from family/friends. Linear regression analyses examined COVID-19 disruption variables as predictors of diabetes distress and depressive severity.

RESULTS

Seventy-three percent and 38% of participants reported elevated diabetes distress and depressive symptoms, respectively. Greater eating disruption predicted higher depressive symptom severity (β=1.33, p=0.045) and eating distress (β=0.28, p=0.045). Greater social support disruption predicted higher eating distress (β=0.36, p=0.019).

CONCLUSIONS

Findings revealed high rates of diabetes distress and depressive symptoms in this T1D sample during the COVID-19 lockdown. Moreover, disruptions in some lifestyle habits and access to social support were associated with worse mental health outcomes.

COVID-19 and common mental health symptoms in the early phase of the pandemic: An umbrella review of the evidence

BACKGROUND

There remains uncertainty about the impact of the Coronavirus Disease 2019 (COVID-19) pandemic on mental health. This umbrella review provides a comprehensive overview of the association between the pandemic and common mental disorders. We qualitatively summarized evidence from reviews with meta-analyses of individual study-data in the general population, healthcare workers, and specific at-risk populations.

METHODS AND FINDINGS

A systematic search was carried out in 5 databases for peer-reviewed systematic reviews with meta-analyses of prevalence of depression, anxiety, and post-traumatic stress disorder (PTSD) symptoms during the pandemic published between December 31, 2019 until August 12, 2022. We identified 123 reviews of which 7 provided standardized mean differences (SMDs) either from longitudinal pre- to during pandemic study-data or from cross-sectional study-data compared to matched pre-pandemic data. Methodological quality rated with the Assessment of Multiple Systematic Reviews checklist scores (AMSTAR 2) instrument was generally low to moderate. Small but significant increases of depression, anxiety, and/or general mental health symptoms were reported in the general population, in people with preexisting physical health conditions, and in children (3 reviews; SMDs ranged from 0.11 to 0.28). Mental health and depression symptoms significantly increased during periods of social restrictions (1 review; SMDs of 0.41 and 0.83, respectively) but anxiety symptoms did not (SMD: 0.26). Increases of depression symptoms were generally larger and longer-lasting during the pandemic (3 reviews; SMDs depression ranged from 0.16 to 0.23) than those of anxiety (2 reviews: SMDs 0.12 and 0.18). Females showed a significantly larger increase in anxiety symptoms than males (1 review: SMD 0.15). In healthcare workers, people with preexisting mental disorders, any patient group, children and adolescents, and in students, no significant differences from pre- to during pandemic were found (2 reviews; SMD's ranging from -0.16 to 0.48). In 116 reviews pooled cross-sectional prevalence rates of depression, anxiety, and PTSD symptoms ranged from 9% to 48% across populations. Although heterogeneity between studies was high and largely unexplained, assessment tools and cut-offs used, age, sex or gender, and COVID-19 exposure factors were found to be moderators in some reviews. The major limitations are the inability to quantify and explain the high heterogeneity across reviews included and the shortage of within-person data from multiple longitudinal studies.

CONCLUSIONS

A small but consistent deterioration of mental health and particularly depression during early pandemic and during social restrictions has been found in the general population and in people with chronic somatic disorders. Also, associations between mental health and the pandemic were stronger in females and younger age groups than in others. Explanatory individual-level, COVID-19 exposure, and time-course factors were scarce and showed inconsistencies across reviews. For policy and research, repeated assessments of mental health in population panels including vulnerable individuals are recommended to respond to current and future health crises.

Time of leaving work pregnancy results during COVID-19 pandemic. The MOACC-19 cohort from Spain

BACKGROUND

COVID-19 pandemic has changed the way pregnancies have been controlled as well as working conditions. In countries with paid leave of work, leaving earlier has been a relevant measure for controlling the pandemic. No study has been published on factors associated with earlier leaving work in pregnancy and the consequences it could have on pregnancy outcomes.

OBJECTIVE

We aimed to identify woman and pregnancy characteristics associated with leaving work earlier and its consequences on pregnancy results.

METHOD

A cohort study was carried out in Cantabria, Northern Spain, including 760 women who were pregnant in 2020 and were working at the beginning of their pregnancy. Data on pregnancy characteristics and results were obtained from medical records and gestational age at leaving work was self-reported. In a logistic regression analysis, leaving work before 26th week of pregnancy was the main effect variable.

RESULTS

Several factors were associated with lower probability of leaving work before 26th week, including university studies (OR = 0.49, 95% CI: 0.36, 0.68), having presential work (OR = 0.57, 95% CI: 0.40, 0.81), women born in non-European countries (OR = 0.55, 95% CI: 0.30, 1.01) and non-smokers (OR for smokers = 1.79, 95% CI: 1.12, 2.87). Neither type of delivery, gestational age at delivery nor other pregnancy results were associated with the gestational age of leaving work.

CONCLUSION

Several pregnancy and women characteristics were associated with leaving work earlier in the COVID-19 pandemic, although it was not associated with any pregnancy outcome.

Chinese pregnant women's knowledge, attitude, and practice of self-protection against coronavirus disease 2019 during the post-pandemic period: A structural equation modeling-based survey

This study aimed to investigate the Chinese pregnant women's levels of knowledge, attitude, and practice (KAP) of self-protection against coronavirus disease 2019 (COVID-19) during the post-pandemic period, to aid the development of targeted health education. An online questionnaire was conducted for 2156 Chinese pregnant women from October 1, 2021, to December 31, 2021, to collect socio-demographic and KAP information. Structural equation modeling (SEM) was used to determine self-protection-related factors. The mean age of the participants was 30 ± 4.1 years. SEM indicated that pregnant women's level of knowledge can directly and indirectly affect the practice of self-protection (r = 0.23) through their belief, with a correlation coefficient of 0.56 and 0.46 between knowledge and belief and belief and practice, respectively. The "basic protection" and "hospital visits after infection" exerted the greatest impact on knowledge formation, with correlation coefficients of 0.85 and 0.89, respectively. Attitude had a direct effect on practice with a correlation coefficient of 0.46. "Awareness of prevention and control" and "family and social support" had the greatest impact on belief formation, with correlation coefficients of 0.77 and 0.73, respectively. Pregnant Chinese women were generally familiar with COVID-19 knowledge, and their levels of knowledge and beliefs particularly affect the practice of self-protection. Health education aimed at improving pregnant women's knowledge and belief toward self-protection against COVID-19 may be an effective way to guide them toward positive practices and promote their health and that of their babies.

Maternal Anxiety and Its Associated Factors During the First and Second Wave of COVID-19 Pandemic in Serbia: A Cross-Sectional Study

Aim

The COVID 19-pandemic affects people differently, while pregnant women are among the most sensitive populations. The data about maternal mental health during the COVID-19 outbreak are in some ways consistent but also country-specific.

Purpose

The study aims to explore the impact of the COVID-19 pandemic on pregnant women's anxiety and identify its associated factors.

Patients and Methods

This cross-sectional study included a sample of 358 pregnant women during the first and second waves of the pandemic in Serbia. An anonymous survey included basic demographic questions, pregnancy-related background questions, the question of self-reported COVID-19-related fear, State-Trait Anxiety Inventory (STAI), and Multidimensional Scale of Perceived Social Support (MSPSS).

Results

The study revealed no pregnant women with low anxiety levels measured by STAI-T and STAI-S, while the STAI-S and STAI-T scores indicated high anxiety in 32.4% and 42.7% of pregnant women, respectively. The obtained results pointed out the nonlinear dependence of state anxiety on observed associated factors and their complex interactions, including the data collecting period.

Conclusion

Our findings reveal that COVID-19 affects pregnant women's mental health and makes it necessary for psychological monitoring and support for pregnant women, which may be reflected in their mental health but also the development of their offspring.

The Impact of COVID-19 on Maternal Mental Health during Pregnancy: A Comparison between Canada and China within the CONCEPTION Cohort

The effect of the COVID-19 pandemic on maternal mental health has been described in Canada and China but no study has compared the two countries using the same standardized and validated instruments. In this study, we aimed to evaluate and compare the impact of COVID-19 public health policies on maternal mental health between Canada and China, as we hypothesize that geographical factors and different COVID-19 policies are likely to influence maternal mental health. Pregnant persons >18 years old were recruited in Canada and China using a web-based strategy. All participants recruited between 26 June 2020 and 16 February 2021 were analyzed. Self-reported data included sociodemographic variables, COVID-19 experience and maternal mental health assessments (Edinburgh Perinatal Depression Scale (EPDS), Generalized Anxiety Disorders (GAD-7) scale, stress and satisfaction with life). Analyses were stratified by recruitment cohort, namely: Canada 1 (26 June 2020-10 October 2020), Canada 2 and China (11 October 2020-16 February 2021). Overall, 2423 participants were recruited, with 1804 participants within Canada 1, 135 within Canada 2 and 484 in China. The mean EDPS scores were 8.1 (SD, 5.1) in Canada 1, 8.1 (SD, 5.2) in Canada 2 and 7.7 (SD, 4.9) in China (p-value Canada 2/China: p = 0.005). The mean GAD-7 scores were 2.6 (SD, 2.9) in China, 4.3 (SD, 3.8) in Canada 1 (p < 0.001) and 5.8 (SD, 5.2) in Canada 2 (p < 0.001). When adjusting for stress and anxiety, being part of the Chinese cohort significantly increased the chances of having maternal depression by over threefold (adjusted OR 3.20, 95%CI 1.77-5.78). Canadian and Chinese participants reported depressive scores nearly double those of other crises and non-pandemic periods. Lockdowns and reopening periods have an important impact on levels of depression and anxiety among pregnant persons.

A survey of coping strategies and resilience in women victims of domestic violence during the COVID-19 pandemic in Tehran, 2020

BACKGROUND

Domestic violence against women is a hidden and global epidemic that has many negative effects. The COVID-19 pandemic, quarantine, and staying at home can lead to violent and domestic violence against women. Due to the importance of the subject, the present study was conducted to investigate the coping strategies and resilience of women victims of domestic violence in the COVID-19 epidemic in Tehran, 2020.

METHODS

The present study is a descriptive-analytical study on 420 women who suffered domestic violence in Tehran, 2020. Data collection tools included a demographic information form, socioeconomic status questionnaire, WHO standardized domestic violence questionnaire, Connor-Davidson Resilience Scale, and Endler and Parker's coping strategies questionnaire. This study was based on the Internet and online. The research poster, the characteristics of the participants, the voluntary participation in the study, the confidentiality of the information, and the link to the online questionnaire were made public through Internet networks.

RESULTS

There was no correlation between resilience with general violence (p =.221), types of physical violence (p =.502), psychological violence (p =.178), and sexual violence (p =.386). The results also showed that there was a statistically significant difference between the women who were using or not using a problem-oriented style with physical violence, using or not using an emotion-oriented style with physical, psychological, sexual violence, and using or not using an avoidance style with physical violence among the samples (p < .05).

CONCLUSION

The use of coping strategies leads to a reduction in domestic violence against women during the COVID-19 pandemic. Therefore, designing and implementing training programs to improve coping styles in women can be effective in dealing with such stressful situations and help prevent injuries caused by violence.

Impact of health literacy on anxiety and depressive symptoms in pregnant women in Japan during the COVID-19 pandemic

To investigate the relationships between communicative and critical health literacy (CCHL) and anxiety and depressive symptoms (ADs) in pregnant women during the coronavirus disease 2019 (COVID-19) pandemic. A cross-sectional study was conducted and 5466 pregnant women responded in Japan in September 2020. A Kessler 6 scale (K6) score ≥ 10, an Edinburgh Postnatal Depression Scale (EPDS) score ≥ 13, and four CCHL groups were analyzed using a logistic regression model and trend test. The proportions of pregnant women with a K6 score ≥ 10 and EPDS score ≥ 13 were 13.5 and 15.4%, respectively. In comparisons with the low CCHL group, the adjusted odds ratio (95% CI) for anxiety symptoms was 0.770 (0.604–0.982) in the high CCHL group, while those for depressive symptoms were 0.777 (0.639–0.946), 0.665 (0.537–0.824), and 0.666 (0.529–0.838) in the lower, higher, and high CCHL groups (all p < 0.05), respectively, after adjustments for potential confounding factors, such as age, weeks of gestation, complications, history, number of children, marital status, education, employment, and income. Higher CCHL was associated with significantly lower adjusted odds ratios for anxiety (p for trend = 0.019) and depressive symptoms (p for trend < 0.001). These results suggest a relationship between CCHL and ADs in pregnant women during the COVID-19 pandemic.

Depression in pregnant and postpartum women during COVID-19 pandemic: systematic review and meta-analysis

Coronavirus disease 2019 (COVID-19) emerged as a global pandemic in March 2020 and caused a big crisis, especially the health crisis. Pregnant and postpartum women experienced significant physical, social, and mental changes that put them at higher risk for several conditions during the pandemic. This study aimed to report the prevalence of depression in pregnant and postpartum women during the COVID-19 pandemic. Eligible studies were identified using several databases. Prevalence analysis was conducted using MedCalc ver. 19.5.1. This systematic review and meta-analysis was registered in PROSPERO on July 12, 2021 with registration number CRD42021266976. We included 54 studies with 95.326 participants. The overall prevalence of depression was 32.60% among pregnant and postpartum women during the COVID-19 pandemic. The rate was higher among pregnant women (31.49%) compared to postpartum women (27.64%). The prevalence of depression among pregnant and postpartum women increased during the COVID-19 pandemic.

The Impact of Maternal Prenatal Stress Related to the COVID-19 Pandemic during the First 1000 Days: A Historical Perspective

The COVID-19 pandemic has a major impact on society, particularly affecting its vulnerable members, including pregnant women and their unborn children. Pregnant mothers reported fear of infection, fear of vertical transmission, fear of poor birth and child outcomes, social isolation, uncertainty about their partner's presence during medical appointments and delivery, increased domestic abuse, and other collateral damage, including vaccine hesitancy. Accordingly, pregnant women's known vulnerability for mental health problems has become a concern during the COVID-19 pandemic, also because of the known effects of prenatal stress for the unborn child. The current narrative review provides a historical overview of transgenerational effects of exposure to disasters during pregnancy, and the role of maternal prenatal stress. We place these effects into the perspective of the COVID-19 pandemic. Hereby, we aim to draw attention to the psychological impact of the COVID-19 pandemic on women of reproductive age (15-49 year) and its potential associated short-term and long-term consequences for the health of children who are conceived, carried, and born during this pandemic. Timely detection and intervention during the first 1000 days is essential to reduce the burden of transgenerational effects of the COVID-19 pandemic.

Consequences of COVID-19 on Health, Economy, and Tourism in Asia: A Systematic Review

Since the beginning of the COVID-19 situation, academic and disaster-related organizations have focused on the severity of COVID-19 and how to prevent the infection. The side effects of COVID-19 also created serious impacts on human lives from multiple perspectives. This study primarily aims to conduct a systematic review on the COVID-19 impacts from the aspects of health, economy, and tourism, focusing on Asia. We use the preferred reporting items for systematic reviews and meta-analyses as the main tool in conducting the systematic review analysis. The keywords related to the focused aspect are searched based on the two prominent academic journal databases: Web of Science and PubMed. In each aforementioned aspect, the consequences and the main stakeholders who were directly and indirectly affected are explained. Moreover, the connection between the three aspects based on the impact of COVID-19, which still continues to intensify, and strategies to prepare for future pandemic situation are also presented.

Estimation of sleep problems among pregnant women during COVID-19 pandemic: a systematic review and meta-analysis

OBJECTIVE

To estimate the sleep problems among pregnant women during the COVID-19 pandemic.

ELIGIBILITY CRITERIA

English, peer-reviewed, observational studies published between December 2019 and July 2021 which assessed and reported sleep problem prevalence using a valid and reliable measure were included.

INFORMATION SOURCES

Scopus, Medline/PubMed Central, ProQuest, ISI Web of Knowledge and Embase.

RISK OF BIAS ASSESSMENT TOOL

The Newcastle-Ottawa Scale checklist.

SYNTHESIS OF RESULTS

Prevalence of sleep problems was synthesised using STATA software V.14 using a random effects model. To assess moderator analysis, meta-regression was carried out. Funnel plot and Egger's test were used to assess publication bias. Meta-trim was used to correct probable publication bias. The jackknife method was used for sensitivity analysis.

INCLUDED STUDIES

A total of seven cross-sectional studies with 2808 participants from four countries were included.

SYNTHESIS OF RESULTS

The pooled estimated prevalence of sleep problems was 56% (95% CI 23% to 88%, I²=99.81%, Tau²=0.19). Due to the probability of publication bias, the fill-and-trim method was used to correct the estimated pooled measure, which imputed four studies. The corrected results based on this method showed that pooled prevalence of sleep problems was 13% (95% CI 0% to 45%; p<0.001). Based on meta-regression, age was the only significant predictor of prevalence of sleep problems among pregnant women.

LIMITATIONS OF EVIDENCE

All studies were cross-sectional absence of assessment of sleep problems prior to COVID-19, and the outcomes of the pregnancies among those with and without sleep problems in a consistent manner are among the limitation of the current review.

INTERPRETATION

Pregnant women have experienced significant declines in sleep quality when faced with the COVID-19 pandemic. The short-term and long-term implications of such alterations in sleep on gestational and offspring outcomes are unclear and warrant further studies.

Impact of SARS-CoV-2 Infection During Pregnancy on Infant Neurobehavioral Development: A Case-Control Study

Background: Previous studies on the pneumonia outbreak caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have focused on the general population and pregnant women, while little is known about the effects of SARS-CoV-2 on retardation during and after pregnancy. The purpose of this study was to evaluate the potential influence of SARS-CoV-2 on infant neurobehavioral development. Methods: A case-control study was conducted in Wuhan Maternal and Child Health Hospital, China. Nine pregnant women with SARS-CoV-2 infection and 9 controls matched by maternal age, parity, and status of chronic disease were included. Infantile neurobehavioral development was assessed through the Ages and Stages Questionnaires Edition 3 (ASQ-3). Results: The majority of pregnant women with SARS-CoV-2 experienced cesarean section (7 of 9), which was higher than the control group (5 of 9). The throat swabs of all newborn were negative. We found that compared with the control group, neonates of mothers with SARS-CoV-2 infection during pregnancy had lower scores in communication, gross movement, fine movement, problem solving, and personal-social domains; but only fine movement domain yielded statistical significance (P = 0.031). Conclusion: Infection with SARS-CoV-2 during pregnancy may have a certain impact on infant neurobehavioral development. Further studies with larger sample size are warranted for validation.
