•Prevalence estimates of posttraumatic and general stress due to COVID-19 are greatly needed.•High rates of posttraumatic and psychological stress in the general population are ...reported.•Methodological quality among reported studies is limited and longitudinal research is needed.•Mental health resources should be mobilized to address stress due to COVID-19.
Emerging evidence suggests rates of posttraumatic stress and psychological stress in the general population are elevated due to COVID-19. However, a meta-analysis is needed to attain more precise prevalence estimates due to between-study variability. Thus, we performed a rapid review and meta-analysis of posttraumatic stress and general psychological stress symptoms during COVID-19. Electronic searches were conducted up to May 26th, 2020 using key terms: mental illness and COVID-19. A total of k = 14 non-overlapping studies were identified for inclusion. Random effects meta-analyses indicated that the pooled prevalence of posttraumatic stress symptoms and psychological stress in the general population was 23.88% and 24.84%, respectively. In both meta-analyses, the prevalence of stress symptoms was higher in unpublished compared to peer-reviewed studies. Overall, nearly one-in-four adults experienced significant stress due to the COVID-19 pandemic. Psychological resources and services must be allocated to help address the mental health burden of COVID-19. High quality, longitudinal research on the long-term mental health effects of the pandemic is greatly needed.
Research regarding the protective effects of early physical activity on depression has yielded conflicting results.
Our objective was to synthesize observational studies examining the association of ...physical activity in childhood and adolescence with depression.
Studies (from 2005 to 2015) were identified by using a comprehensive search strategy.
The included studies measured physical activity in childhood or adolescence and examined its association with depression.
Data were extracted by 2 independent coders. Estimates were examined by using random-effects meta-analysis.
Fifty independent samples (89 894 participants) were included, and the mean effect size was significant (
= -0.14; 95% confidence interval CI = -0.19 to -0.10). Moderator analyses revealed stronger effect sizes in studies with cross-sectional versus longitudinal designs (
= 36,
= -0.17; 95% CI = -0.23 to -0.10 vs
= 14,
= -0.07; 95% CI = -0.10 to -0.04); using depression self-report versus interview (
= 46,
= -0.15; 95% CI = -0.20 to -0.10 vs
= 4,
= -0.05; 95% CI = -0.09 to -0.01); using validated versus nonvalidated physical activity measures (
= 29,
= -0.18; 95% CI = -0.26 to -0.09 vs
= 21,
= -0.08; 95% CI = -0.11 to -0.05); and using measures of frequency and intensity of physical activity versus intensity alone (
= 27,
= -0.17; 95% CI = -0.25 to -0.09 vs
= 7,
= -0.05; 95% CI = -0.09 to -0.01).
Limitations included a lack of standardized measures of physical activity; use of self-report of depression in majority of studies; and a small number of longitudinal studies.
Physical activity is associated with decreased concurrent depressive symptoms; the association with future depressive symptoms is weak.
To examine the prenatal and postnatal mechanisms by which maternal adverse childhood experiences (ACEs) predict the early development of their offspring, specifically via biological (maternal health ...risk in pregnancy, infant health risk at birth) and psychosocial risk (maternal stress during and after pregnancy, as well as hostile behavior in early infancy).
Participants were 1994 women (mean age = 31 years) and their infants, who were recruited in pregnancy as part of a prospective longitudinal cohort from 2008 to 2010. Pregnant women completed self-report questionnaires in pregnancy and postpartum related to psychosocial risk and a questionnaire about hostile behavior when their infant was 4 months of age. Health risk in pregnancy and infant health risk at birth were obtained from health records. Mothers completed the Ages and Stages Questionnaire when infants were 12 months of age.
Path analysis revealed that the association between maternal ACEs and infant development outcomes at 12 months operated through 2 indirect pathways: biological health risk (pregnancy health risk and infant health risk at birth) and psychosocial risk (maternal psychosocial risk in pregnancy and maternal hostile behavior in infancy).
Psychosocial risks in pregnancy, but not in early infancy, contribute to the transmission of vulnerability from maternal ACEs to child development outcomes in infancy via maternal behavior. Maternal health risk in pregnancy indirectly confers risk from maternal ACEs to child development outcomes at 12 months of age through infant health risk. Maternal health and psychosocial well-being in pregnancy may be key targets for intervention.
Summary Women’s sleep quality has been reported to change during pregnancy; prevalence estimates of poor sleep quality during pregnancy vary widely. To further understand the observed variation of ...findings, we conducted a meta-analysis to quantify the prevalence of poor sleep quality during pregnancy. Articles (N = 24) that reported prevalence of poor sleep quality as captured by the Pittsburgh sleep quality index (PSQI) ≥ 5 were included, with a total of 11,002 participants contributing data. PubMed, PsycINFO, and Web of Science databases were systematically searched. Results indicated that the average PSQI score during pregnancy was 6.07, 95% Confidence Interval (CI) 5.30, 6.85, and 45.7%, 95% CI 36.5%, 55.2%, of pregnant women experienced poor sleep quality. Longitudinal studies indicated that sleep quality decreased from second ( M = 5.31, SE = 0.40) to third trimester ( M = 7.03, SE = 0.85) by 1.68 points, 95% CI 0.42, 2.94. Gestational age moderated the average PSQI scores and prevalence of PSQI scores ≥ 5; older samples reported higher mean PSQI scores and higher prevalence of poor sleep quality. Clinicians should be aware that some reduction in sleep quality is expected during pregnancy, but complaints of very poor sleep quality could require intervention. Future research should examine various factors underlying poor sleep quality during pregnancy.
Investigations have found mothers’ adverse childhood experiences (ACEs) confer an intergenerational risk to their children's outcomes. However, mechanisms underlying this transmission have only been ...partially explained by maternal mental health. Adult attachment insecurity has been shown to mediate the association of ACEs and mental health outcomes, yet an extension of this research to children's behavioral problems has not been examined.
To examine the cascade from maternal ACEs to risk for child behavioral problems at five years of age, via mothers’ attachment insecurity and mental health.
Participants in the current study were 1994 mother-child dyads from a prospective longitudinal cohort collected from January 2011 to October 2014.
Mothers retrospectively reported their ACEs when children were 36 months of age. When children were 60 months of age, mothers completed measures of their attachment style, depression and anxiety symptoms, and their children's behavior problems.
Path analysis demonstrated maternal ACEs were associated with children's internalizing problems indirectly via maternal attachment avoidance, attachment anxiety, and depression symptoms, but not directly (β = .05, 95% CI −.001, .10). Maternal ACEs indirectly predicted children's externalizing problems via maternal attachment avoidance, attachment anxiety, and depression. A direct effect was also observed from maternal ACEs to child externalizing problems (β = .06, 95% CI .01, .11).
Maternal ACEs influenced children's risk for poor behavioral outcomes via direct and indirect intermediary pathways. Addressing maternal insecure attachment style and depression symptoms as intervention targets for mothers with histories of ACEs may help to mitigate the intergenerational transmission of risk.
•Higher stress and anxiety predict higher anxiety and stress at later time points.•Increases in partner and family support predict decreases in stress and anxiety.•Increases in stress and anxiety ...lead to decreases in support.•Increases in social support in one domain promote increases in other domains.
Stress and anxiety in pregnancy and the postpartum period are associated with poor long-term maternal and child health outcomes. Social support has been shown to mitigate the effects of maternal stress and anxiety; however, the directionality and longitudinal associations among these variables are poorly understood. Using a novel multilevel modeling approach called dynamic structural equation modeling (DSEM), we examined within-person (state-level) autoregressive and cross-lagged associations among stress, anxiety, and social support in the perinatal period in order to elucidate directional associations over time.
Mothers from a longitudinal pregnancy cohort (N = 3,388) completed self-report measures of stress, anxiety, and social support across 4 time points from pregnancy to 12 months postpartum.
Higher than average levels of stress and anxiety led to elevations in anxiety and stress and decreases in social support at subsequent time points. Importantly, earlier individual levels of partner and family support predicted subsequent decreases in stress and anxiety.
Support was measured via maternal self-report thus extrapolations cannot be made to tangible or instrumental supports and lagged relationships represent average lags over time.
Using a novel statistical approach, these results suggest that increases in both partner and family support may be powerful protective factors for decreasing mental health difficulties in pregnancy and the postpartum, highlighting the importance of targeting and increasing this type of support from pregnancy to the postpartum period.
Twenty years ago, meta-analytic results (k = 19) confirmed the association between caregiver attachment representations and child-caregiver attachment (Van IJzendoorn, 1995). A test of caregiver ...sensitivity as the mechanism behind this intergenerational transmission showed an intriguing "transmission gap." Since then, the intergenerational transmission of attachment and the transmission gap have been studied extensively, and now extend to diverse populations from all over the globe. Two decades later, the current review revisited the effect sizes of intergenerational transmission, the heterogeneity of the transmission effects, and the size of the transmission gap. Analyses were carried out with a total of 95 samples (total N = 4,819). All analyses confirmed intergenerational transmission of attachment, with larger effect sizes for secure-autonomous transmission (r = .31) than for unresolved transmission (r = .21), albeit with significantly smaller effect sizes than 2 decades earlier (r = .47 and r = .31, respectively). Effect sizes were moderated by risk status of the sample, biological relatedness of child-caregiver dyads, and age of the children. Multivariate moderator analyses showed that unpublished and more recent studies had smaller effect sizes than published and older studies. Path analyses showed that the transmission could not be fully explained by caregiver sensitivity, with more recent studies narrowing but not bridging the "transmission gap." Implications for attachment theory as well as future directions for research are discussed.
Parents have faced substantial social and economic challenges during the COVID-19 pandemic. Preliminary cross-sectional research has demonstrated increases in mental health problems in mothers during ...the COVID-19 pandemic compared with pre-pandemic estimates. We aimed to study an existing longitudinal cohort of mothers to assess changes in the prevalence of maternal depression and anxiety symptoms as a result of the COVID-19 pandemic over time and at the individual level.
In this longitudinal observational study, women who took part in the All Our Families pregnancy cohort in Canada were invited to complete a COVID-19 impact survey between May 20 and July 15, 2020. Women who had not agreed to additional research, had discontinued, were lost to follow-up, or who were not contactable via email were excluded. Maternal depression and anxiety symptoms during the COVID-19 pandemic were compared with three previous estimates collected at 3, 5, and 8-year timepoints (between April, 2012, and October, 2019). Depression symptoms were assessed using the 10-item Center for Epidemiological Studies Depression scale and anxiety symptoms were assessed using the short form of the Spielberger State-Trait Anxiety Inventory. Repeated cross-sectional analyses were done to assess temporal trends and fixed-effects regression models were fitted to assess within-person change over time.
Of the 3387 women included in the All Our Families study, 2445 women were eligible and were invited to participate in the COVID-19 impact study, of whom 1333 consented to participate, and 1301 were included in the longitudinal analysis. At the COVID-19 impact survey timepoint, a higher proportion of mothers had clinically significant depression (35·21%, 95% CI 32·48-38·04) and anxiety symptoms (31·39%, 28·76-34·15) than at all previous data collection timepoints. The mean depression score (8·31, 95% CI 7·97-8·65) and anxiety score (11·90, 11·66-12·13) at the COVID-19 pandemic timepoint were higher than previous data collection waves at the 3-year timepoint (mean depression score 5·05, 4·85-5·25; mean anxiety score 9·51, 9·35-9·66), 5-year timepoint (mean depression score 5·43, 5·20-5·66; mean anxiety score 9·49, 9·33-9·65), and 8-year timepoint (mean depression score 5·79, 5·55-6·02; mean anxiety score 10·26, 10·10-10·42). For the within-person comparisons, depression scores were a mean of 2·30 points (95% CI 1·95-2·65) higher and anxiety scores were a mean of 1·04 points (0·65-1·43) higher at the COVID-19 pandemic timepoint, after controlling for time trends. Larger increases in depression and anxiety symptoms were observed for women who had income disruptions, difficulty balancing home schooling with work responsibilities, and those with difficulty obtaining childcare. White mothers had greater increases in anxiety scores than non-white mothers and health-care workers had smaller increases in depressive symptoms than non-health-care workers.
Compared with previous estimates, the prevalence of maternal depression and anxiety among mothers in a Canadian cohort increased during the COVID-19 pandemic. Financial support, childcare provision, and avoiding the closure of schools, might be key priorities for preventing future increases in maternal psychological distress.
