Associations between postpartum depressive symptoms and childhood asthma diminish with child age

Adverse childhood experiences (ACEs) and repeated wheezing from 6 to 30 months of age: exploring the role of race and ethnicity

Identifying children at risk for respiratory disorders involves understanding early risk factors. This study prospectively examines how specific types of early adversity influence childhood wheeze and how these vary by race and ethnicity. Analyses included N = 746 mother-infant dyads from an urban pregnancy cohort. Mothers completed the Lifetime Stressor Checklist-Revised (LSC-R), Edinburgh Postnatal Depression Scale (EPDS), Spielberger State-Trait Anxiety Inventory (STAI), Posttraumatic stress disorder Checklist-Civilian version (PCL-C), and Traumatic Events Screening Inventory (TESI) when infants were 6 months old to assess adverse childhood experiences (ACEs). Mothers reported child wheeze at 4-month intervals to index wheezing episodes from age 6-30 months. We first assessed independent associations between ACE measures and wheeze frequency using Poisson regression. We then used weighted quantile sum (WQS) regression to derive an ACEs mixture index to estimate joint associations with wheeze frequency in the overall sample and stratified by maternal race and ethnicity adjusting for child sex, maternal asthma and education. There was a 2.05 increase (95% CI = 1.21, 3.49) in wheeze frequency with each quintile increase of the ACEs index in Black/Black Hispanics; the TESI (72%) contributed most strongly to the mixture. In non-Black Hispanics, there was a 1.33 (95% CI = 1.05, 1.67) increase in wheeze frequency with each ACEs quintile increase with EPDS (76%) contributing most strongly. Findings support the need to move the ACEs paradigm beyond a simple cumulative score when examining effects on early respiratory disease risk. Results also highlight how the impact of early life ACEs varies by ethnoracial identity.

Perinatal maternal depression and the risk of childhood asthma in offspring: A meta-analysis

BACKGROUND

Previous studies have yielded conflicting results regarding the link between maternal perinatal depression and asthma in children. To provide a clearer understanding of this relationship, a comprehensive meta-analysis was carried out to evaluate the association mentioned above.

METHODS

A comprehensive review of observational studies was conducted by searching electronic databases including Medline, Embase, and Web of Science. The data were combined using a randomized-effects model taking into account potential variations. Subgroup analyses were performed to evaluate the possible impact of study characteristics on outcomes.

RESULTS

Ten cohort studies, which included 833,230 mother-child pairs, were examined in the analysis. Maternal depressive symptoms during the perinatal period were associated with an increased risk of asthma in offspring (risk ratio [RR]: 1.24, 95% confidence interval [CI]: 1.19 to 1.30, p < 0.001; I2 = 0%). Further sensitivity analyses restricted to multivariate studies (RR: 1.24, 95% CI: 1.19 to 1.30, p < 0.001; I2 = 0%) or studies where asthma was diagnosed in children aged three years or older (RR: 1.24, 95% CI: 1.19 to 1.30, p < 0.001; I2 = 0%) revealed consistent outcomes. Subgroup analyses according to study design, methods for the diagnosis of maternal depression, timing for the evaluation of maternal depression, methods for the validation of asthma in offspring, adjustment of maternal smoking during pregnancy and of maternal asthma, or study quality score showed similar results (p for subgroup difference all > 0.05).

CONCLUSIONS

Maternal perinatal depression appears to be significantly linked to a higher occurrence of childhood asthma in children.

Maternal mental illness and child atopy: a UK population-based, primary care cohort study

BACKGROUND

The number of children exposed to maternal mental illness is rapidly increasing and little is known about the effects of maternal mental illness on childhood atopy.

AIM

To investigate the association between maternal mental illness and risk of atopy among offspring.

DESIGN AND SETTING

Retrospective cohort study using a UK primary care database (674 general practices).

METHOD

In total, 590 778 children (born 1 January 1993 to 30 November 2017) were followed until their 18th birthday, with 359 611 linked to their hospital records. Time-varying exposure was captured for common (depression and anxiety), serious (psychosis), addiction (alcohol and substance misuse), and other (eating and personality disorder) maternal mental illness from 6 months before pregnancy. Using Cox regression models, incidence rates of atopy were calculated and compared for the exposed and unexposed children in primary (asthma, eczema, allergic rhinitis, and food allergies) and secondary (asthma and food allergies) care, adjusted for maternal (age, atopy history, smoking, and antibiotic use), child (sex, ethnicity, and birth year/season), and area covariates (deprivation and region).

RESULTS

Children exposed to common maternal mental illness were at highest risk of developing asthma (adjusted hazard ratio [aHR] 1.17, 95% confidence interval [CI] = 1.15 to 1.20) and allergic rhinitis (aHR 1.17, 95% CI = 1.13 to 1.21), as well as a hospital admission for asthma (aHR 1.29, 95% CI = 1.20 to 1.38). Children exposed to addiction disorders were 9% less likely to develop eczema (aHR 0.91, 95% CI = 0.85 to 0.97) and 35% less likely to develop food allergies (aHR 0.65, 95% CI = 0.45 to 0.93).

CONCLUSION

The finding that risk of atopy varies by type of maternal mental illness prompts important aetiological questions. The link between common mental illness and childhood atopy requires GPs and policymakers to act and support vulnerable women to access preventive (for example, smoking cessation) services earlier.

Parental Mental Health and Childhood Respiratory Outcomes in a Severe Bronchiolitis Cohort

Parental mental health conditions appear to contribute to the development of childhood respiratory illness. We investigated the relationship between parental mental health and childhood respiratory illness using data from a 17-center prospective cohort study of infants hospitalized with bronchiolitis between 2011 and 2014 (n = 921). Among 779 (84.6%) participants with self-reported parental mental health history data, 184 (23.6%) had parental history of depression and 155 (19.9%) had anxiety. Multivariable analyses found that both parental history of depression (hazard ratio [HR] 1.41, 95% confidence interval [CI] 1.01-1.99) and anxiety (HR 1.28, 95% CI 1.08-1.52) were associated with an increased risk of recurrent wheezing by age 3 years. However, only parental history of anxiety was associated with asthma by age 5 years (odds ratio 1.79, 95% CI 1.25-2.55). Further research on exposure severity, other early life stressors, and effective methods of parental psychosocial support is needed to develop targeted risk factor prevention strategies to reduce the burden of childhood respiratory illness.

Feasibility and Acceptability of Internet-based Interpersonal Psychotherapy for Stress, Anxiety, and Depression in Prenatal Women: Thematic Analysis Abstract (Preprint)

Background

Prenatal mental health is a global health concern. Despite the far-reaching impact of prenatal mental health issues, many women do not receive the psychological care they require. Women in their childbearing years are frequent users of the internet and smartphone apps. Prenatal women are prime candidates for internet-based support for mental health care.

Objective

This study aimed to examine the feasibility and acceptability of internet-based interpersonal psychotherapy (IPT) for prenatal women.

Methods

Semistructured interviews were conducted with women who had received internet-based IPT modules with guided support as a component of a randomized controlled trial evaluating the scale-up implementation of a digital mental health platform (The Healthy Outcomes of Pregnancy and Postpartum Experiences digital platform) for pregnant women. Qualitative thematic analysis was used to explore and describe women’s experiences. Data were analyzed for emerging themes, which were identified and coded.

Results

A total of 15 prenatal women were interviewed to examine their experiences and views on the feasibility and acceptability of internet-based IPT modules. Participants found the content informative and appreciated the ways in which the digital mental health platform made the IPT modules accessible to users. Participants voiced some differing requirements regarding the depth and the way information was presented and accessed on the digital mental health platform. The important areas for improvement that were identified were acknowledging greater depth and clarity of content, the need for sociability and relationships, and refinement of the digital mental health platform to a smartphone app.

Conclusions

This study provides useful evidence regarding treatment format and content preferences, which may inform future development. It also provides research data on the feasibility and acceptability of web-based applications for prenatal mental health care.

Parental mental health, socioeconomic position and the risk of asthma in children-a nationwide Danish register study

Background

Parental mental illness affects child health. However, less is known about the impact of different severities of maternal depression and anxiety as well as other mental health conditions. The objective of this study was to examine the impact of different severities of maternal and paternal mental health conditions on child asthma.

Methods

This nationwide, register-based cohort study included all children in Denmark born from 2000 to 2014. Exposure was parental mental health conditions categorized in three severities: minor (treated at primary care settings), moderate (all ICD-10 F-diagnoses given at psychiatric hospital) and severe (diagnoses of severe mental illness). The children were followed from their third to sixth birthday. Child asthma was identified by prescribed medication and hospital-based diagnoses. Incidence rate ratios were calculated using negative binomial regression analyses.

Results

The analyses included 925 288 children; 26% of the mothers and 16% of the fathers were classified with a mental health condition. Exposed children were more likely to have asthma (10.6–12.0%) compared with unexposed children (8.5–9.0%). The three severities of mental health conditions of the mother and the father increased the risk of child asthma, most evident for maternal exposure. Additive interaction between maternal mental health conditions and disadvantaged socioeconomic position was found.

Conclusion

We found an increased risk of asthma in exposed children, highest for maternal exposure. Not only moderate and severe, but also minor mental health conditions increased the risk of child asthma. The combination of mental health condition and disadvantaged socioeconomic position for mothers revealed a relative excess risk.

Adverse childhood experiences and asthma: trajectories in a national cohort

Objective

Research has linked early adverse childhood experiences (ACEs) with asthma development; however, existing studies have generally relied on parent report of exposure and outcome. We aimed to examine the association of early life ACEs with empirically determined trajectories of childhood asthma risk, using independent register information on both exposures and outcome.

Methods

Based on nationwide registries, we established a study cohort of 466 556 children born in Denmark (1997–2004). We obtained information on ACEs during the first 2 years of life (bereavement, parental chronic somatic and/or mental illness) and childhood asthma diagnosis or medication use from birth through age 10 years from the Danish National Patient and Prescription Registries, respectively. We identified asthma phenotypes using group-based trajectory modelling. We then used multinomial logistic regression to examine the association between early ACEs and asthma phenotypes.

Results

We identified four asthma phenotypes: non-asthmatic, early-onset transient, early-onset persistent and late-onset asthma. Girls with early-onset transient asthma (OR 1.13, 95% CI 1.04 to 1.24), early-onset persistent asthma (1.27, 95% CI 1.08 to 1.48) or late-onset asthma (OR 1.28, 95% CI 1.11 to 1.48) vs no asthma were more likely to have early life ACE exposure compared with girls without ACE exposure. Results were similar for boys who also had experienced early life ACEs with ORs of 1.16 (95% CI 1.08 to 1.25), 1.34 (95% CI 1.20 to 1.51) and 1.11 (95% CI 0.98 to 1.25), respectively.

Conclusion

In a nationwide-population study, we identified three childhood onset asthma phenotypes and found that ACEs early in life were associated with increased odds for each of these asthma phenotypes among both girls and boys.

Effects of parental mental illness on children's physical health: systematic review and meta-analysis

BACKGROUND

Children of parents with mental disorder face multiple challenges.

AIMS

To summarise evidence about parental mental disorder and child physical health.

METHOD

We searched seven databases for cohort or case-control studies quantifying associations between parental mental disorders (substance use, psychotic, mood, anxiety, obsessive-compulsive, post-traumatic stress and eating) and offspring physical health. Studies were excluded if: they reported perinatal outcomes only (<28 days) or outcomes after age 18; they measured outcome prior to exposure; or the sample was drawn from diseased children. A meta-analysis was conducted. The protocol was registered on the PROSPERO database (CRD42017072620).

RESULTS

Searches revealed 15 945 non-duplicated studies. Forty-one studies met our inclusion criteria: ten investigated accidents/injuries; eight asthma; three other atopic diseases; ten overweight/obesity; ten studied other illnesses (eight from low-and middle-income countries (LMICs)). Half of the studies investigated maternal perinatal mental health, 17% investigated paternal mental disorder and 87% examined maternal depression. Meta-analysis revealed significantly higher rates of injuries (OR = 1.15, 95% CI 1.04-1.26), asthma (OR = 1.26, 95% CI 1.12-1.41) and outcomes recorded in LMICs (malnutrition: OR = 2.55, 95% CI 1.74-3.73; diarrhoea: OR = 2.16, 95% CI 1.65-2.84). Evidence was inconclusive for obesity and other atopic disorders.

CONCLUSIONS

Children of parents with mental disorder have health disadvantages; however, the evidence base is limited to risks for offspring following postnatal depression in mothers and there is little focus on fathers in the literature. Understanding the physical health risks of these vulnerable children is vital to improving lives. Future work should focus on discovering mechanisms linking physical and mental health across generations.

Maternal Distress During Pregnancy and Recurrence in Early Childhood Predicts Atopic Dermatitis and Asthma in Childhood

BACKGROUND

Early-life stress is becoming an important determinant of immune system programming. Maternal prenatal distress is found to be associated with atopic disease in offspring but the separate effects of postnatal distress are not well-studied.

RESEARCH QUESTION

Does the likelihood of asthma and atopic dermatitis in children increase when they are exposed to maternal distress pre- and postnatally in a sex-specific manner?

STUDY DESIGN AND METHODS

Using data from a provincial newborn screen and health-care database for 12,587 children born in 2004, maternal distress (depression or anxiety) was defined as prenatal, self-limiting, recurrent, or late-onset postpartum. Atopic dermatitis (AD) and asthma at ages 5 years and 7 years of age were diagnosed by using hospitalization, physician visit, or prescription records. Associations between maternal distress and childhood asthma and AD were determined by using multiple logistic regression.

RESULTS

After adjusting for risk factors, a significant association between maternal prenatal (OR, 1.27; 95% CI, 1.11-1.46), recurrent postpartum (OR, 1.28; 95% CI, 1.11-1.48), and late-onset postpartum (OR, 1.19, 95% CI, 1.06-1.34) distress was found with AD at age 5 years. Asthma at age 7 years was also associated with maternal prenatal distress (OR, 1.57; 95% CI, 1.29-1.91) and late-onset postnatal distress (OR, 1.22; 95% CI, 1.01-1.46). Self-limiting postnatal distress was not found to be a risk factor for either atopic condition. Associations with AD or asthma were of a similar magnitude in boys and girls; the exception was recurrent postnatal distress, which increased risk for asthma in boys only.

INTERPRETATION

This population-based study provides evidence for sex-specific associations between maternal prenatal and postnatal distress, as well as the development of AD and asthma. The findings support recommendations for greater psychosocial support of mothers during pregnancy and early childhood to prevent childhood atopic disease.

Maternal psychological distress before birth influences gut immunity in mid-infancy

BACKGROUND

Maternal pre-postnatal psychosocial distress increases the risk for childhood allergic disease. This may occur through a host immunity pathway that involves intestinal secretory immunoglobulin A (sIgA). Experimental animal models show changes in the gut microbiome and immunity of offspring when exposed to direct or prenatal maternal stress, but little is known in humans.

OBJECTIVE

We determined the association between maternal depression and stress symptom trajectories and infant fecal sIgA concentrations.

METHODS

1043 term infants from the Canadian Healthy Infant Longitudinal Development (CHILD) birth cohort were studied. Trajectories of maternal perceived stress and depression were based on scored scales administered in pregnancy and postpartum. sIgA was quantified in infant stool (mean age 3.7 months) with Immundiagnostik ELISA. Linear regression and logistic regression were employed to test associations.

RESULTS

Very low fecal sIgA concentrations were more common in infants of mothers in the antepartum and persistent depression trajectories (6% and 2% of women, respectively). Independent of breastfeeding status at fecal sampling, infant antibiotic exposure or other covariates, the antepartum depressive symptom trajectory was associated with reduced mean infant sIgA concentrations (β=-0.07, P < .01) and a two fold risk for lowest quartile concentrations (OR, 1.86; 95% CI: 1.02, 3.40). This lowering of sIgA yielded a large effect size in older infants (4-8 months)-breastfed and not. No associations were seen with postpartum depressive symptoms (7% of women) or with any of the perceived stress trajectories.

CONCLUSION AND CLINICAL RELEVANCE

Despite improved mood postpartum and independent of breastfeeding status, mothers experiencing antepartum depressive symptoms delivered offspring who exhibited lower fecal sIgA concentrations especially in later infancy. The implications of lowered sIgA concentrations in infant stool are altered microbe-sIgA interactions, greater risk for C difficile colonization and atopic disease in later years.

Maternal psychosocial risk factors and lower respiratory tract infection (LRTI) during infancy in a South African birth cohort

Objective

To investigate the association between maternal antenatal and/or postnatal psychosocial risk factors (including depression, psychological distress, alcohol abuse and intimate partner violence (IPV) and infant lower respiratory tract infection (LRTI) in a low- and middle-income-country (LMIC).

Study design

Pregnant women (n = 1137) enrolled in a South African birth cohort study, the Drakenstein Child Health Study (DCHS) were longitudinally assessed for psychosocial risk factors including depression, psychological distress, alcohol abuse and/or intimate partner violence (IPV). Infants were followed from birth until one year of age for the development of LRTI by active surveillance. Two outcomes were evaluated: any LRTI, and severe and/or hospitalised LRTI. Logistic regression was used to identify associations between individual maternal psychosocial risk factors and LRTI outcomes. Analyses stratified by age were also performed to determine which age groups related to infant LRTI were linked with maternal psychosocial risk factors.

Results

There were 606 LRTI episodes in 369 infants in the first year (crude incidence rate = 0.53 episodes per person-year, 95%CI: 0.50; 0.56); 31% (n = 186) of episodes were severe or hospitalised events. Maternal psychosocial risk factors were associated with LRTI and severe LRTI, particularly postnatal and long-term maternal psychological distress, antenatal maternal alcohol consumption, and postnatal maternal IPV. Age stratified analyses found that antenatal maternal alcohol consumption was associated with early infant LRTI, while antenatal maternal depression was linked with infant severe LRTI between 3 and 6 months of age, and postnatal maternal IPV was associated with early LRTI and severe forms of LRTI.

Conclusion

The associations between maternal psychosocial risk factors and infant LRTI highlight the potential value of screening for maternal psychosocial risk factors in clinical settings and developing targeted interventions. Such interventions may not only improve maternal well-being, but also help reduce the burden of infant LRTI in LMIC settings.

Internet-based interpersonal psychotherapy for stress, anxiety, and depression in prenatal women: study protocol for a pilot randomized controlled trial

BACKGROUND

Psychological distress, defined as depression, anxiety and perceived stress, during pregnancy is common, with 15-25% of women experiencing clinically significant levels of such distress. Despite the far-reaching impact of prenatal psychological distress on mothers and their children, and that women are receptive to screening, few providers routinely screen for prenatal psychological distress and less than one in five women will receive the mental health care that they require. There is a lack of certainty regarding the most effective treatments for prenatal psychological distress. No online interpersonal psychotherapy (IPT) trials have been conducted that focus on improving psychological distress in prenatal women. The purpose of this pilot randomized controlled trial is to evaluate the perspectives of pregnant women on the feasibility and acceptability of online IPT (e-IPT) delivered during pregnancy.

METHODS

A pilot randomized controlled trial design with repeated measures will evaluate the feasibility and acceptability of e-IPT for pregnant women compared to routine prenatal care. Qualitative interviews with 15-30 individuals in the intervention group will provide further data on the feasibility and acceptability of the intervention. Assessment of feasibility will include the ease of accessing and completing the intervention. Women will also be asked about what barriers there were to starting and completing the e-IPT. Assessment of acceptability will inquire about the perception of women regarding the intervention and its various features. A sample size of 160 consenting pregnant women aged 18 years and older will be enrolled and randomized into the experimental (e-IPT) or control (routine care) condition. The secondary outcome measures include: depression, anxiety and stress symptoms; self-efficacy; self-mastery; self-esteem; relationship quality (spouse, immediate family members); coping; and resilience. All participants will complete the aforementioned measures at baseline during pregnancy (T1), 3 months postrandomization (T2), at 8 months of pregnancy (T3), and 3 months postpartum (T4).

DISCUSSION

The results of this pilot randomized controlled trial will provide data on the feasibility and acceptability of the intervention and identify necessary adaptations. This study will allow for optimization of full trial processes and inform the evaluation strategy, including sample size calculations for the full randomized controlled trial.

Associations between maternal mental health and early child wheezing in a South African birth cohort

BACKGROUND

Wheezing in early childhood is common and has been identified in high-income countries (HIC) as associated with maternal antenatal or postnatal psychosocial risk factors. However, the association between maternal mental health and childhood wheezing has not been well studied in low and middle-income countries (LMIC), such as South Africa.

METHODS

A total of 1137 pregnant women over 18 year old, between 20 and 28 weeks' gestation, and attending either of two catchment area clinics were enrolled in a South African parent study, the Drakenstein Child Health Study (DCHS). Psychosocial risk factors including maternal depression, psychological distress, early adversity, and intimate partner violence (IPV), were measured antenatally and postnatally by validated questionnaires. Two outcomes were evaluated: Presence of wheeze (at least one episode of child wheeze during the first 2 years of life); and recurrent wheeze (two or more episodes of wheezing in a 12-month period). Logistic regression was used to investigate the association between antenatal or postnatal psychosocial risk factors and child wheeze, adjusting for clinical and socio-demographic covariates.

RESULTS

Postnatal psychological distress and IPV were associated with both presence of wheeze (adjusted OR = 2.09, 95%CI: 1.16-3.77 and 1.63, 95%CI: 1.13-2.34, respectively), and recurrent child wheeze (adjusted OR = 2.26, 95%CI: 1.06-4.81 and 2.20, 95%CI: 1.35-3.61, respectively).

CONCLUSION

Maternal postnatal psychological distress and IPV were associated with wheezing in early childhood. Thus, screening and treatment programs to address maternal psychosocial risk factors may be potential strategies to reduce the burden of childhood wheeze in LMICs.

Evidence establishing a link between prenatal and early-life stress and asthma development

PURPOSE OF REVIEW

The objective of this review is to provide an update on our evolving understanding of the effects of stress in pregnancy and during early development on the onset of asthma-related phenotypes across childhood, adolescence, and into early adulthood.

RECENT FINDINGS

Accumulating evidence over the past 2 decades has established that prenatal and early-life psychological stress and stress correlates (e.g., maternal anxiety or depression) increase the risk for childhood respiratory disorders. Recent systematic reviews and meta-analyses including numerous prospective epidemiological and case-control studies substantiate a significant effect of prenatal stress and stress in early childhood on the development of wheeze, asthma, and other atopic-related disorders (eczema and allergic rhinitis), with many studies showing an exposure-response relationship. Offspring of both sexes are susceptible to perinatal stress, but effects differ. The impact of stress on child wheeze/asthma can also be modified by exposure timing. Moreover, coexposure to prenatal stress can enhance the effect of chemical stressors, such as prenatal traffic-related air pollution, on childhood respiratory disease risk. Understanding complex interactions among exposure dose, timing, child sex, and concurrent environmental exposures promises to more fully characterize stress effects and identify susceptible subgroups. Although the link between perinatal stress and childhood asthma-related phenotypes is now well established, pathways by which stress predisposes children to chronic respiratory disorders are not as well delineated. Mechanisms central to the pathophysiology of wheeze/asthma and lung growth and development overlap and involve a cascade of events that include disrupted immune, neuroendocrine, and autonomic function as well as oxidative stress. Altered homeostatic functioning of these integrated systems during development can enhance vulnerability to asthma and altered lung development.

SUMMARY

Mechanistic studies that more comprehensively assess biomarkers reflecting alterations across interrelated stress response systems and associated regulatory processes, in both pregnant women and young children, could be highly informative. Leveraging high-throughput systems-wide technologies to include epigenomics (e.g., DNA methylation, microRNAs), transcriptomics, and microbiomics as well as integrated multiomics are needed to advance this field of science. Understanding stress-induced physiological changes occurring during vulnerable life periods that contribute to chronic respiratory disease risk could lead to the development of preventive strategies and novel therapeutic interventions.

Risk and Protective Factors for Mental Health and Community Cohesion After the 2013 Calgary Flood

OBJECTIVE

To examine mental health and community cohesion in women living in Calgary after a natural disaster considering previously collected mental health data.

METHODS

Data from an ongoing longitudinal cohort, the All Our Families study, were used to examine mental health and community cohesion 5 months after a major flood in Calgary, Canada. Participants who had completed a baseline questionnaire before the flood were eligible for inclusion in this study (N=923). Four multivariable logistic regression models were built to examine predictors of post-traumatic stress, depression, anxiety, and community cohesion.

RESULTS

Elevated anxiety before the flood was associated with 2.49 (95% CI: 1.17, 5.26) increased odds of experiencing high levels of post-traumatic stress, regardless of whether respondents lived in a flood-risk community or not. Women who experienced damage to property, or who provided help to others, were more likely to perceive an increased sense of community cohesion (adjusted ods ratio (AOR): 1.67; 95% CI: 1.09, 2.54 and AOR: 1.68; 95% CI: 1.13, 2.52, respectively).

CONCLUSIONS

Women with underlying mental health conditions may be more vulnerable to the psychological impacts of a natural disaster regardless of their level of exposure. Natural disasters may bring communities together, especially those who were more tangibly impacted. (Disaster Med Public Health Preparedness. 2018;12:470-477).
