The psychological impact of exposure to floods

The Effects of Hydrological Disasters on the Population's Health in the Northeast Region of Brazil

The Northeast region of Brazil is characterized by long periods of drought. However, the region is also frequently affected by floods. The socioeconomic characteristics of the locality make the population more vulnerable to the impacts of these disasters. Therefore, the aim of this article is to investigate the short to long-term impacts of hydrological disasters in northeastern Brazil on morbidity and mortality rates, by age groups. For this purpose, the difference-in-differences method proposed by Callaway and Sant'Anna was applied to a monthly panel data spanning the period from 2000 to 2012. The results indicate that in the short term there is an increase in the mortality rate associated with drowning. In the medium term, there are effects particularly on morbidity rates, with emphasis on leptospirosis and acute respiratory diseases. For the long-term diseases analyzed, no effects of hydrological disasters were observed.

Enhancing community resilience in the context of trauma: The Morandi Bridge collapse in Italy

Community resilience increases collective capacity to enact change and restore communities following trauma. Using the Beyond the Bridge Project as a case study following the Morandi Bridge Collapse, we conducted 10 consultations with the Project Lead Group. We employed a stakeholder analysis, and ecological maps performed using the Communities Advancing Resilience Toolkit methodology. The findings highlight the involvement and categorization of stakeholders based on their post-trauma intervention attitudes. The ecological maps facilitated communication and community competence between different stakeholder groups, which are key aspects of community resilience. We suggest that this methodology is promising for future research in trauma-affected communities.

Flooding and health in Australia: a scoping review and coauthorship analysis of published research

BACKGROUND

Australia is frequently affected by floods, and their severity and frequency are predicted to increase due to the effects of climate change. Over the past decade, there has been an increase in the number of publications reporting on the health impacts of flooding in Australia, but no synthesis of this research evidence has previously been published. The aim of this scoping review is to identify and map publications on the health impacts of flooding in Australia and to describe the networks of researchers contributing to this research.

METHODS

In the study, we applied the scoping review methodology guided by Johanna Briggs Institute and coauthorship network analysis. Searches were conducted in MEDLINE, Embase, PsycINFO, CINHAL, Scopus and Web of Science for all publications up to 31 December 2023. Screening, full-text review and data extraction were completed by two independent reviewers. Coauthor networks were constructed using social network analysis methods.

RESULTS

69 publications were included, spanning a 70-year period from 1951 to 2023. The top three health impacts studied were post-traumatic stress disorder (PTSD), distress and child developmental outcomes, with the predominant focus in the past 10 years of recent publications on prenatal maternal stress, child outcomes and mental health impacts. There was minimal focus on socially vulnerable groups and long-term health impacts and few qualitative research studies were reported. Coauthorship analysis showed the primarily disease-specific nature of flood-related research.

CONCLUSION

Our review enhances understanding of the research on the physical and mental health impacts of flooding in Australia by identifying the areas of relatively greater research activity, existing research gaps and potential future research priorities. Given the context-dependent nature of flood and other climate-related health impacts, and of mitigation and adaptation responses, we anticipate that our review findings will enhance the understanding of this topic for Australia and other higher-income countries, identifying areas of focus and current research gaps.

A longitudinal investigation of mental health outcomes after the Henan floods in China: Examining predictors of resilience trajectories

A heavy rainstorm struck Henan, China, in July 2021. Previous studies have indicated that natural disasters have a wide range of psychological sequelae, but little research has been done on the psychological effects of floods specifically. This study aimed to track the mental health trajectories of flood victims over time and identify associated protective and risk factors. People living in the areas most impacted by the flood (N = 376) were surveyed at four different time points: 3 weeks, 1 month, 2 months, and 3 months post-flood. Latent growth mixture modeling was utilized to delineate longitudinal patterns of depression, anxiety, and posttraumatic stress disorder (PTSD). Least absolute shrinkage and selection operator logistic regression, a supervised machine-learning approach, was employed to discern predictors among 49 assessed variables at both contextual and personal levels. Results revealed three classes of PTSD (resilience, recovery, moderate symptoms) and anxiety (resilience, chronicity, recovery) trajectories, along with two classes of depression trajectories (resilience, chronicity). Key factors predicting resilience in mental health included personality traits, media consumption habits, pre-existing health conditions at the individual level, and asset loss and ongoing adversities at the contextual level. In spite of the widespread impact of the flood, most victims displayed resilience in the face of adversity. Identifying critical factors across various psychological symptoms offers valuable insights for both pre-disaster preparation and post-disaster trans-diagnostic psychological interventions.

Predicting Participation in a Post-disaster Mental Health Program

OBJECTIVES

A retrospective naturalistic evaluation was undertaken to identify if pre- and post-disaster factors may predict the likelihood of those considered "at risk" of post-traumatic stress disorder (PTSD) entering a post-disaster clinical treatment program.

METHODS

The intake data of 881 people referred to the program following the Queensland (Australia) natural disasters of 2010-11 was evaluated. Those referred scored >2 on the Primary Care PTSD scale. Assessment included the disaster exposure experience, demographic and clinical information, and measures of coping and resilience. Descriptive analyses and a Classification Tree Analysis (CTA) were undertaken to ascertain which factors may predict treatment participation.

RESULTS

The treatment group (TG) in comparison to the non-treatment group (NTG) were more likely to perceive their life was threatened (85.1% vs 8.1%), less able to cope (67% vs 25.8%) and less resilient (4.2% vs 87.5%). The CTA using all the assessment variables found the Connor-Davidson (2-item scale) (P < 0.001), degree of property damage (P < 0.001), financial losses (P < 0.001), perception their life was threatened (P < 0.001) and insurance claims (P < 0.003) distinguished the TG from the NTG.

CONCLUSIONS

The study identified factors that distinguished the TG from the NTG and predicted the likelihood of participation in a post-disaster mental health treatment.

The Impact of "Soft" and "Hard" Flood Adaptation Measures on Affected Population's Mental Health: A Mixed Method Scoping Review

BACKGROUND

The frequency and severity of floods has increased in different regions of the world due to climate change. It is important to examine how adaptation measures impact the mental health of individuals affected by these disasters.

OBJECTIVE

The goal of this scoping review was to document the existing studies on the impact of flood adaptation measures in affected populations to identify the best preventive strategies and limitations that deserve further exploration.

METHODS

This study followed the PRISMA-ScR guidelines. Inclusion criteria focused on studies in English or French available in MEDLINE and Web of Science that examined the impact of adaptation measures on the mental health of flood victims. Literature reviews or non-study records were excluded from the analysis.

RESULTS

A total of 857 records were obtained from the examined databases. After 2 rounds of screening, 9 studies were included for full-text analysis. Six studies sought to identify the factors that drive resilience in flood victims, whereas 3 studies analyzed the impact of external interventions on their mental health.

CONCLUSIONS

The limited number of studies demonstrates the need for public health policies to develop flood adaptation measures that can be used to support the mental health of flood victims.

Syndromic Surveillance in Public Health Emergencies: A Systematic Analysis of Cases Related to Exposure to 2023 Floodwaters in Romagna, Italy

BACKGROUND

In May 2023, Romagna, Italy, faced a devastating flood resulting in 16 fatalities, forced displacement of 26,000 citizens, and significant economic losses. Due to potential water contamination, implementing public health strategies became imperative for the Local Health Authority to mitigate the health consequences, analyze the flood's impact on the local population's health, and detect early anomalies requiring timely public health interventions.

METHODS

Between June and July 2023, general practitioners who were part of the RespiVirNet surveillance network completed weekly structured forms. These forms collected data on individuals exposed or not to floodwaters and clinical syndromes. Rates per 1000 resident population aged > 14 were stratified by district, week of observation, and symptomatology. Missing data were addressed by imputation using second-order autoregressive modeling.

RESULTS

An incidence of 3.52 syndromes potentially related to flood water exposure per 1000 individuals (95% CI 2.82-4.35) was estimated. Ravenna, the city most affected by the flood, recorded the highest rate (6.05 per 1000, 95% CI 4.59-7.82). Incidence decreased in the weeks post-event. Anxiety, or trauma and stress symptoms, exhibited higher rates among the exposed, diminishing over weeks. The incidence for the non-exposed (12.76 per 1000, 95% CI 10.55-15.29) showed no significant territorial differences compared to the exposed ones.

CONCLUSIONS

Syndromic surveillance provided timely information on the flood's health impact, revealing a higher incidence of individual syndromes among the non-exposed. This study contributes to guiding the implementation of future public health preparedness and response strategies for populations facing similar natural disasters.

Effects of tropical cyclone Freddy on the social determinants of health: the narrative review of the experience in Malawi

Malawi-one of the low-income countries in Africa-has witnessed a series of flood-related disasters in many years. The recent tropical cyclone Freddy (TCF) has indispensable effects on the unequal distribution of the social determinants of health with tendencies for increased disease outbreaks across the districts of the country. This narrative study aimed at unravelling the consequences of the TCF and its possible relationship with the already existing cholera epidemic in the fourteen affected districts. Additionally, it aimed to document the immediate humanitarian responses in the acute phase of the disaster. We identified, used and extracted information and data from relevant documents available from the government records, WHO and other multiagency documents, which were summarised along with the humanitarian actions and the associated implications of the entire event. Areas of TCF's main effects included health, shelter, education, nutrition, water sanitation and hygiene, agriculture and livelihood, transport and logistics including food security. The notable immediate humanitarian responses are donations, camp creation for accommodations, emergency life-saving response and essential healthcare services. Nsanje and Chikwawa districts experienced an increase in cholera cases and deaths post-TCF. The highest proportion of the disaster-impacted and intervention beneficiaries were women and children. The effects of the TCF on the social determinants of health in the affected districts and the associated negative impacts should be considered by the government and disaster management experts in evidence-based policy-making towards disaster risk reduction in the flood-prone districts using an all-hazard approach. This step might be useful in improving the vulnerable population's standard of living and achievement of related Sustainable Development Goals in Malawi.

Post-traumatic stress disorder, food insecurity, and social capital after the 2017 coastal El Niño flooding among mothers from Piura, Peru: A mixed method study

In order to understand the impacts in the post-disaster scenario of the 2017 El Niño events in the Piura region-Peru, we examined post-traumatic stress disorder (PTSD), food insecurity (FI), and social capital (SC) across three-time points in mothers in highly affected areas. In the Piura, Castilla, and Catacaos districts, we studied mothers combining mixed-method assessments at three (June-July 2017), eight and 12 months after the flooding. Each outcome was measured with the PTSD-Checklist-Civilian (PCL-C), the Household-Food-Insecurity-Access-Scale (HFIAS), the Adapted-Social-Capital-Assessment-Tool (SASCAT) surveys. In-depth interviews at the first evaluation were also conducted. At the first evaluation, 38.1% (n = 21) of 179 mothers reported PTSD; eight months and one year after the flooding, it dropped to 1.9% and virtually zero, respectively. Severe FI also declined over time, from 90.0% three months after the flooding to 31.8% eight months after, to 13.1% one year after. Conversely, high-cognitive SC was increased three months after the flooding (42.1%) and much greater levels at eight and 12 months after (86.7% and 77.7%, respectively). High levels of PTSD and severe FI three months after the flooding consistently decreased to nearly zero one-year post-disaster. High levels of high-cognitive SC may have helped mothers to recover from PTSD and FI in Piura.

Flood Risk and Preventive Choices: A Framework for Studying Human Behaviors

The topic of flood phenomena has always been of considerable importance due to the high risks it entails, both in terms of potential economic and social damage and the jeopardizing of human lives themselves. The spread of climate change is making this topic even more relevant. This work aims to contribute to evaluating the role that human factors can play in responding to critical hydrogeological phenomena. In particular, we introduce an agent-based platform for analyzing social behaviors in these critical situations. In our experiments, we simulate a population that is faced with the risk of a potentially catastrophic event. In this scenario, citizens (modeled through cognitive agents) must assess the risk they face by relying on their sources of information and mutual trust, enabling them to respond effectively. Specifically, our contributions include (1) an analysis of some behavioral profiles of citizens and authorities; (2) the identification of the "dissonance between evaluation and action" effect, wherein an individual may behave differently from what their information sources suggest, despite having full trust in them in situations of particular risk; (3) the possibility of using the social structure as a "social risk absorber", enabling support for a higher level of risk. While the results obtained at this level of abstraction are not exhaustive, they identify phenomena that can occur in real-world scenarios and can be useful in defining general guidelines.

Perspectives on early insights: pediatric cancer caregiving amidst natural calamities - A call for future preparedness

Natural disasters cause immense damage and disruption to the environment, human lives, and property, posing a threat to safety and well-being. These disasters annually affect individuals and communities, severely impacting mental health. Research indicates a significant link between catastrophic events and an increased risk of mental disorders, including anxiety, depression, substance use, and post-traumatic stress disorder (PTSD). Individuals with chronic conditions, like cancer patients, are particularly vulnerable post-disaster due to disrupted healthcare services. The recent earthquake in Morocco highlighted the urgent need for continued care, especially for vulnerable populations living in poverty. Soleterre Foundation's interventions focus on supporting young cancer patients and their families, emphasizing psychological support following the earthquake. Effective disaster response needs coordinated efforts, clear roles, communication, and standardized healthcare procedures, especially for vulnerable groups like cancer patients. Education programs for patients and clinicians are vital for disaster preparedness. Communication challenges and lack of medical history further emphasize the need for well-defined disaster preparedness plans and continued care guidelines for cancer patients.

Flood exposure and pregnancy loss in 33 developing countries

Floods have affected billions worldwide. Yet, the indirect health impacts of floods on vulnerable groups, particularly women in the developing world, remain underexplored. Here, we evaluated the risk of pregnancy loss for women exposed to floods. We analyzed 90,465 individual pregnancy loss records from 33 developing countries, cross-referencing each with spatial-temporal flood databases. We found that gestational flood exposure is associated with increased pregnancy loss with an odds ratio of 1.08 (95% confidence interval: 1.04 - 1.11). This risk is pronounced for women outside the peak reproductive age range (<21 or >35) or during the mid and late-stage of pregnancy. The risk escalated for women dependent on surface water, with lower income or education levels. We estimated that, over the 2010s, gestational flood events might be responsible for approximately 107,888 (CIs: 53,944 - 148,345) excess pregnancy losses annually across 33 developing countries. Notably, there is a consistent upward trend in annual excess pregnancy losses from 2010 to 2020, and was more prominent over Central America, the Caribbean, South America, and South Asia. Our findings underscore the disparities in maternal and child health aggravated by flood events in an evolving climate.

Climate Change and the Esophagus: Speculations on Changing Disease Patterns as the World Warms

PURPOSE OF REVIEW

Esophageal disorders, including gastroesophageal reflux disease (GERD), eosinophilic esophagitis (EoE), and esophageal cancer, may be affected by climate change. Our review describes the impact of climate change on risk factors associated with esophageal diseases and speculates how these climate-related factors impacted esophageal disorders and their management.

RECENT FINDINGS

Climate change is responsible for extreme weather conditions (shifts in rainfall, floods, droughts, and forest fires) and global warming. These consequences affect basic human needs of water and food, causing changes in population dynamics and pose significant threats to digestive health, including common esophageal disorders like GERD, EoE, and esophageal cancers. The changing patterns of esophageal diseases with climate change are likely mediated through risk factors, including nutrition, pollutants, microplastics, and the microbiota-gut-brain axis. The healthcare process itself, including GI endoscopy practices commonly employed in diagnosing and therapeutics of esophageal diseases, may, in turn, contribute to climate change through plastic wastage and greenhouse gas emissions, thus creating the climate change lifecycle. Breaking the cycle would involve changes at the individual level, community level, and national policy level. Prevention is key, with individuals identifying and remediating risk factors and reducing carbon footprints. The ABC (Advocacy, Broadcast, and Collaborate) activities would help enhance awareness at the community level. Higher-level programs such as the Bracing Resilience Against Climate Effects (BRACE) would lead to broader and larger-scale adoption of public health adaptation strategies at the national level. The impact of climate change on esophageal disorders is likely real, mediated by several risk factors, and creates a climate change lifecycle that may only break if changes are made at individual, community, and national levels.

Help-seeking following a flooding event: a cross-sectional analysis of adults affected by flooding in England in winter 2013/14

BACKGROUND

Flooding can cause long-term, significant impacts on mental health in affected populations. We explored help-seeking behaviour of households affected by flooding.

METHODS

A cross-sectional analysis was conducted on National Study of Flooding and Health data on households flooded in England in winter 2013/14. Participants (Year 1: n = 2006; Year 2: n = 988; Year 3: n = 819) were asked if they sought help from health services and other sources. Logistic regression was conducted to calculate odds ratios (ORs) of help-seeking in flooded and disrupted participants compared to unaffected, adjusted for a priori confounders.

RESULTS

The odds of seeking help from any source 1 year after flooding were greater for flooded participants [adjusted OR (aOR): 1.71, 95% confidence interval (CI): 1.19-1.45] and those disrupted by flooding (aOR: 1.92, 95% CI: 1.37-2.68) compared to unaffected participants. This continued in the second year (flooded: aOR 6.24, 95% CI: 3.18-13.34; disrupted: aOR: 2.22, 95% CI: 1.14-4.68), and help-seeking remained greater in flooded than unaffected participants in the third year. Flooded and disrupted participants were particularly likely to seek help from informal sources. Help-seeking was more prevalent amongst participants with mental health outcomes, but a notable proportion of individuals with any mental health outcome did not seek help (Year 1: 15.0%; Year 2: 33.3%; Year 3: 40.3%).

CONCLUSIONS

Flooding is associated with increased demand for formal and informal support, persisting for at least 3 years, and an unmet need for help amongst affected individuals. Our findings should be considered in flood response planning to reduce the long-term adverse health impacts of flooding.

Opportunistic Mental Health Screening: Is there a Role Following a Disaster? Lessons from the 2010-2011 Queensland (Australia) Floods and Cyclones

BACKGROUND

Following the 2010-2011 floods and cyclones that affected 78% of Queensland, Australia, a State-wide mental health response was established. The response plan included a 24-hour access line. This study examines the effectiveness of the mental health screening program conducted via the State-wide health call center (13HEALTH) in 2012.

METHODS

Callers to the 13HEALTH line were screened to assess the impact of the disaster. The 13HEALTH clinicians administered the Primary Care-Posttraumatic Stress Disorder Scale (PC-PTSD) screening measure. Those scoring more than two on the PC-PTSD Scale were provided information on the emotional impact of disasters and a referral to the post-disaster specialist mental health program (SMHP). For calls related to those under 18, a single-item question assessed behavioral or emotional changes since the natural disasters. Those with identified changes were offered a referral to a post-disaster SMHP.The study evaluates the relationship between disaster exposure and the likelihood of 13HEALTH callers experiencing physical health concerns and unacknowledged mental health symptoms. The program's cost for the 12 months of 2012 was assessed using data from the financial contract.

RESULTS

In 2012, there were 205,064 calls to 13HEALTH: 19,708 identified as residing in a flood or cyclone-affected area, 7,315 adults indicated they were personally affected, and 907 scored more than two on the PC-PTSD Scale. Only 700 agreed to a referral to the SMHP. There were 290 children under 18 assessed as at risk; 207 accepted a referral to a SMHP.Regions that experienced a greater impact from the floods and cyclones were 1.3-2.3 times more likely to report being personally affected by the floods and cyclones. Similarly, these regions had more callers scoring more than two on the PC-PTSD Scale. The total cost of the 13HEALTH program for 2012 was $53,284 (AU) across all age groups.

CONCLUSION

The 13HEALTH general health post-disaster screening program demonstrates opportunistic screening may assist identification of those with unmet mental health needs. The data indicate an increased likelihood of personal exposure in the more affected regions with an increased risk of unrecognized psychological symptoms as assessed by the PC-PTSD Scale. However, more than 20% declined referral to a SMHP.

Mental Health Disorders Due to Disaster Exposure: A Systematic Review and Meta-Analysis

Natural disasters are complex, global issues that affect people individually, families, and communities, upsetting their emotional wellbeing. This research aims to comprehend the connections between disasters and their effects on mental health. We conducted a systemic review and meta-analysis on the effect of disasters on mental health disorders using defined search terms across three major databases. The search technique adhered to the PECO framework. The study locations were dispersed across Asia, Europe, and America. An electronic search was established in the Cochrane Central Register of Controlled Trials in the Cochrane Library, PubMed, and Medline databases. A random-effects meta-analysis was carried out. The I2 statistic was used to explore heterogeneity. In the random-effects analysis, Tau-squared, τ2, or Tau2 evaluates the effects seen between the study variances. Publication bias was examined. The outcomes of the included studies on mental health issues (n = 48,170) brought on by catastrophic disasters were pooled using a random-effects meta-analysis. The three main mental health illnesses attributed to the disaster catastrophe in most studies were generalized anxiety disorder (GAD), depression, substance use, adjustment disorder, and post-traumatic stress disorder (PTSD). Storms, including cyclones and snowstorms, had an impact on 5,151 individuals. 38,456 people were harmed by flooding, and 4,563 people were affected by the earthquake. The included studies showed prevalence rates for mental health disorders ranging from 5.8% to 87.6%. The prevalence rates were between 2.2% and 84% for anxiety, 3.23% and 52.70% for depression, and 2.6% and 52% for PTSD, respectively. The point effect estimates of studies included the flood, storm/cyclone, and earthquake were 0.07 (95% confidence interval [CI]: 0.02-0.12), 0.18 (95% CI: 0.03-0.32), and 0.15 (95% CI: 0.03-0.27), respectively, which revealed a statistically significant positive effect (p-value: < 0.05) with a narrow 95% CI indicating more precise population estimates. However, the pooled effect estimates were not of a large effect size of 0.129 (95% CI: 0.05-0.20). This study found a link between disaster and poorer outcomes for mental health. The risk of psychological morbidity and fatalities increased with relocation and disruption of essential services. Flooding was the most frequent calamity. The "medium human development countries" were found to have the highest prevalence rate of mental health disorders in our meta-analysis. The "very high human development" and "high human development" nations, however, also had a higher prevalence rate of mental health disorders following catastrophic events. This study could aid in the creation of thorough strategies for the mitigation and avoidance of mental health problems during natural disasters. Increased community resilience, improved access to healthcare services, and a suitable mitigation strategy can all help to improve the situation of the disaster's vulnerable population.

The Impact of Climate Change on Mental Health and Emotional Wellbeing: A Narrative Review of Current Evidence, and its Implications

Converging global evidence highlights the dire consequences of climate change for human mental health and wellbeing. This paper summarises literature across relevant disciplines to provide a comprehensive narrative review of the multiple pathways through which climate change interacts with mental health and wellbeing. Climate change acts as a risk amplifier by disrupting the conditions known to support good mental health, including socioeconomic, cultural and environmental conditions, and living and working conditions. The disruptive influence of rising global temperatures and extreme weather events, such as experiencing a heatwave or water insecurity, compounds existing stressors experienced by individuals and communities. This has deleterious effects on people's mental health and is particularly acute for those groups already disadvantaged within and across countries. Awareness and experiences of escalating climate threats and climate inaction can generate understandable psychological distress; though strong emotional responses can also motivate climate action. We highlight opportunities to support individuals and communities to cope with and act on climate change. Consideration of the multiple and interconnected pathways of climate impacts and their influence on mental health determinants must inform evidence-based interventions. Appropriate action that centres climate justice can reduce the current and future mental health burden, while simultaneously improving the conditions that nurture wellbeing and equality. The presented evidence adds further weight to the need for decisive climate action by decision makers across all scales.

Climate Change Related Catastrophic Rainfall Events and Non-Communicable Respiratory Disease: A Systematic Review of the Literature

Climate change is increasing the frequency and intensity of extreme precipitation events, the impacts of which disproportionately impact urban populations. Pluvial flooding and flooding related sewer backups are thought to result in an increase in potentially hazardous human-pathogen encounters. However, the extent and nature of associations between flooding events and non-communicable respiratory diseases such as chronic bronchitis, asthma, and chronic obstructive pulmonary disease (COPD) are not well understood. This research seeks to characterize the state of research on flooding and NCRDs through a systematic review of the scientific literature. We conducted a systematic search of PubMed, Web of Science, and Scopus for published scholarly research papers using the terms flooding, monsoon, and tropical storm with terms for common NCRDs such as asthma, COPD, and chronic bronchitis. Papers were included if they covered research studies on individuals with defined outcomes of flooding events. We excluded review papers, case studies, and opinion pieces. We retrieved 200 articles from PubMed, 268 from Web of Science and 203 from Scopus which comprised 345 unique papers. An initial review of abstracts yielded 38 candidate papers. A full text review of each left 16 papers which were included for the review. All papers except for one found a significant association between a severe weather event and increased risk for at least one of the NCRDs included in this research. Our findings further suggest that extreme weather events may worsen pre-existing respiratory conditions and increase the risk of development of asthma. Future work should focus on more precisely defining measure of health outcomes using validated tools to describe asthma and COPD exacerbations. Research efforts should also work to collect granular data on patients’ health status and family history and assess possible confounding and mediating factors such as neighborhood water mitigation infrastructure, housing conditions, pollen counts, and other environmental variables.

Risks to the Health of Russian Population from Floods and Droughts in 2010‒2020: A Scoping Review

Climate change and natural disasters caused by hydrological, meteorological, and climatic causes have a significant and increasing direct and indirect impact on human health, leading to increased mortality and morbidity. Russia is a country that suffers from frequent climatic and weather disasters. This is mainly due to its vast territory, complex geographical and ecological environment, and widely varying climatic conditions. This review provides information on climatological and hydrological extremes in Russia in 2010–2020, floods and droughts, and their impact on the health and well-being of the country’s population. A literature search was conducted using electronic databases Web of Science, Pubmed, Science Direct, Scopus, and e-Library, focusing on peer-reviewed journal articles published in English and in Russian from 2010 to 2021. Four conceptual categories were used: “floods”, “droughts”, “human health”, and “Russia”. It is concluded that while most hazardous weather events cannot be completely avoided, many health impacts can potentially be prevented. The recommended measures include early warning systems and public health preparedness and response measures, building climate resilient health systems and other management structures.

Testing the public's response to receiving severe flood warnings using simulated cell broadcast

European Governments must implement a public alerting system to reach mobile phone users affected by major emergencies and disasters by June 2022. Cell Broadcast is used to issue emergency alerts in several countries but has not yet been introduced in the UK. This paper presents the results of a joint research exercise that explored recipients' responses to cell broadcast messages that warned of floods of varying certainty, severity, and urgency. We adopted a mixed-methods approach employing semi-structured questions and focus groups to assess the perceptions of 80 workshop participants who received simulated emergency alerts on pre-prepared handsets. Our results suggest that although emergency alerting is welcomed, it is necessary to provide accurate and verifiable information, address accessibility challenges, and state location clearly and understandably. This life-saving technology, if used aptly by not over-alerting, specifying the specific urgency, certainty, severity and location of the flood risk, has the real potential of upgrading flood warnings in the UK.

Anxiety, Anger and Depression Amongst Low-Income Earners in Southwestern Uganda During the COVID-19 Total Lockdown

Background: Low-income earners are particularly vulnerable to mental health, consequence of the coronavirus disease 2019 (COVID-19) lockdown restrictions, due to a temporary or permanent loss of income and livelihood, coupled with government-enforced measures of social distancing. This study evaluates the mental health status among low-income earners in southwestern Uganda during the first total COVID-19 lockdown in Uganda. Methods: A cross-sectional descriptive study was undertaken amongst earners whose income falls below the poverty threshold. Two hundred and fifty-three (n = 253) male and female low-income earners between the ages of 18 and 60 years of age were recruited to the study. Modified generalized anxiety disorder (GAD-7), Spielberger's State-Trait Anger Expression Inventory-2 (STAXI-2), and Beck Depression Inventory (BDI) tools as appropriate were used to assess anxiety, anger, and depression respectively among our respondents. Results: Severe anxiety (68.8%) followed by moderate depression (60.5%) and moderate anger (56.9%) were the most common mental health challenges experienced by low-income earners in Bushenyi district. Awareness of mental healthcare increased with the age of respondents in both males and females. A linear relationship was observed with age and depression (r = 0.154, P = 0.014) while positive correlations were observed between anxiety and anger (r = 0.254, P < 0.001); anxiety and depression (r = 0.153, P = 0.015) and anger and depression (r = 0.153, P = 0.015). Conclusion: The study shows the importance of mental health awareness in low resource settings during the current COVID-19 pandemic. Females were identified as persons at risk to mental depression, while anger was highest amongst young males.

The Mediating Effect of Coping Strategies Between Psychological Capital and Small Tourism Organization Resilience: Insights From the COVID-19 Pandemic, Malaysia

Amid difficulty, the psychological capital of small tourism firm owners/managers has been given less attention. In the coronavirus disease-2019 (COVID-19) pandemic, this research examined how psychological capital (self-efficacy, hope, optimism, and resilience) affects organizational resilience. By structural equation modeling (AMOS 21.0), 644 small tourism firm owners in Malaysia were randomly selected to investigate the relationship between psychological capital and organizational resilience, and the mediating effect of problem-focused and emotion-focused coping strategies on this relationship. The findings of the study supported hypothesized relationships, as the psychological capital of small tourism firm owners in Malaysia significantly affects organizational resilience. Furthermore, the study discovered that problem-focused and emotion-focused coping strategies have partial mediating effects on the association between psychological capital and organizational resilience. In the context of small tourism businesses sector, the findings of the study have implications, as the firms identify the recovery procedure in the COVID-19 pandemic.

Household food insecurity, income loss, and symptoms of psychological distress among adults following the Cyclone Amphan in coastal Bangladesh

INTRODUCTION

Cyclone Amphan swept into Bangladesh's southwestern coast at the end of May 2020, wreaking havoc on food security and economic stability, as well as possibly worsening mental health. We studied the prevalence of post-cyclone stressors in adults following the cyclone and its association with symptoms of psychological distress.

METHODS

We conducted a cross-sectional study in a coastal district of Bangladesh. A five-item brief symptom rating scale was used to measure the symptoms of psychological distress. Household food insecurity was measured using the USAID Household Food Insecurity Access Scale questionnaire. We estimated adjusted prevalence ratios (aPRs) using robust log-linear models adjusted for potential confounders.

RESULTS

A total of 478 adults (mean [SD] age, 37.0[12.6] years; 169[35.4%] women) participated in the study. The prevalence of moderate-to-severe psychological symptoms and suicidal ideation was 55.7% and 10.9%, respectively. Following the cyclone, 40.8% of the adults reported severe food insecurity, and 66% of them reported moderate-to-severe mental health symptoms. Also, 54.4% of women and 33.7% of men reported severe food insecurity in the households. Moreover, 25.5% of respondents reported no income or a significant income loss after the cyclone, and 65.5% of them had moderate-to-severe psychological symptoms. Also, 13.8% of respondents reported housing displacement because of severely damaged houses, and 68.2% of them reported moderate-to-severe psychological symptoms. The high prevalence of mental health symptoms was found in women (aPR = 1.41, 95% CI = 1.06-1.82), people with severe food insecurity (aPR = 1.63, 95% CI = 1.01-2.64), and people who lost jobs or lost a major income source (aPR = 1.25, 95% CI = 1.02-1.54).

CONCLUSION

Following cyclone Amphan, many low-income individuals saw their income drop drastically while others were unemployed and living with severe food insecurity. The result suggests gender inequalities in food-security after the cyclone. Immediate action is needed to ensure household food-security for reducing the burden of mental illness. Rising opportunities of paid-jobs and decreasing income-loss, especially for the poor people, can have a protective impact on psychological distress. However, due to the high prevalence of severe psychological symptoms, long-term mental health services are required among the population of coastal Bangladesh.

Spirituality, religiosity and the mental health consequences of social isolation during Covid-19 pandemic

BACKGROUND

Evidence shows that religiosity and spirituality (R/S) are highly used in critical moments of life and that these beliefs are associated with clinical outcomes. However, further studies are needed to assess these beliefs during the COVID-19 pandemic.

AIMS

To evaluate the use of R/S during the COVID-19 pandemic in Brazil and to investigate the association between R/S and the mental health consequences of social isolation.

METHODS

Cross-sectional study conducted in May 2020. Online surveys were carried out assessing sociodemographics, R/S measures, and social isolation characteristics and mental health consequences (hopefulness, fear, worrying and sadness). Adjusted regression models were used.

RESULTS

A total of 485 participants were included from all regions of Brazil. There was a high use of religious and spiritual beliefs during the pandemic and this use was associated with better mental health outcomes. Lower levels of worrying were associated with greater private religious activities (OR = 0.466, CI 95%: 0.307-0.706), religious attendance (OR = 0.587, CI 95%: 0.395-0.871), spiritual growth (OR = 0.667, CI 95%: 0.448-0.993) and with an increase in religious activities (OR = 0.660, CI 95%: 0.442-0.986); lower levels of fear were associated with greater private religious activities (OR = 0.632, CI 95%: 0.422-0.949) and spiritual growth (OR = 0.588, CI 95%: 0.392-0.882) and, lower levels of sadness (OR = 0.646, CI 95%: 0.418-0.997) were associated with spiritual growth. Finally, hope was associated with all R/S variables in different degrees (ranging from OR = 1.706 to 3.615).

CONCLUSIONS

R/S seem to have an important role on the relief of suffering, having an influence on health outcomes and minimizing the consequences of social isolation. These results highlight the importance of public health measures that ensure the continuity of R/S activities during the pandemic and the training of healthcare professionals to address these issues.

Recurrent Home Flooding in Detroit, MI 2012-2020: Results of a Household Survey

Household flooding has wide ranging social, economic and public health impacts particularly for people in resource poor communities. The determinants and public health outcomes of recurrent home flooding in urban contexts, however, are not well understood. A household survey was used to assess neighborhood and household level determinants of recurrent home flooding in Detroit, MI. Survey activities were conducted from 2012 to 2020. Researchers collected information on past flooding, housing conditions and public health outcomes. Using the locations of homes, a "hot spot" analysis of flooding was performed to find areas of high and low risk. Survey data were linked to environmental and neighborhood data and associations were tested using regression methods. 4803 households participated in the survey. Flooding information was available for 3842 homes. Among these, 2085 (54.26%) reported experiencing pluvial flooding. Rental occupied units were more likely to report flooding than owner occupied homes (Odd ratio (OR) 1.72 [95% Confidence interval (CI) 1.49, 1.98]). Housing conditions such as poor roof quality and cracks in basement walls influenced home flooding risk. Homes located in census tracts with increased percentages of owner occupied units (vs. rentals) had a lower odds of flooding (OR 0.92 [95% (CI) 0.86, 0.98]). Household factors were found the be more predictive of flooding than neighborhood factors in both univariate and multivariate analyses. Flooding and housing conditions associated with home flooding were associated with asthma cases. Recurrent home flooding is far more prevalent than previously thought. Programs that support recovery and which focus on home improvement to prevent flooding, particularly by landlords, might benefit the public health. These results draw awareness and urgency to problems of urban flooding and public health in other areas of the country confronting the compounding challenges of aging infrastructure, disinvestment and climate change.

Economic Evaluation of Mental Health Effects of Flooding Using Bayesian Networks

The appraisal of appropriate levels of investment for devising flooding mitigation and to support recovery interventions is a complex and challenging task. Evaluation must account for social, political, environmental and other conditions, such as flood state expectations and local priorities. The evaluation method should be able to quickly identify evolving investment needs as the incidence and magnitude of flood events continue to grow. Quantification is essential and must consider multiple direct and indirect effects on flood related outcomes. The method proposed is this study is a Bayesian network, which may be used ex-post for evaluation, but also ex-ante for future assessment, and near real-time for the reallocation of investment into interventions. The particular case we study is the effect of flood interventions upon mental health, which is a gap in current investment analyses. Natural events such as floods expose people to negative mental health disorders including anxiety, distress and post-traumatic stress disorder. Such outcomes can be mitigated or exacerbated not only by state funded interventions, but by individual and community skills and experience. Success is also dampened when vulnerable and previously exposed victims are affected. Current measures evaluate solely the effectiveness of interventions to reduce physical damage to people and assets. This paper contributes a design for a Bayesian network that exposes causal pathways and conditional probabilities between interventions and mental health outcomes as well as providing a tool that can readily indicate the level of investment needed in alternative interventions based on desired mental health outcomes.

Designing "Safer Water." A Virtual Reality Tool for the Safety and the Psychological Well-Being of Citizens Exposed to the Risk of Natural Disasters

Virtual Reality (VR) is a popular technology to recreate reality-like scenarios, including dangerous ones, in a realistic but safe way. Because of this potential, VR based research has been applied in psychology studies to provide training and education about how to behave in emergencies such as fires, earthquakes, floods, or typhoons. All these different virtual scenarios have been built to observe how people react to emergencies, what behaviors they adopted, what level of stress is generated, and finally, how to increase citizens' safety. However, there is still little research that shows how Virtual Environment (VE) should be designed to convey appropriate social and psychological “cues” to participants. In this work, we present the result of a series of co-design sessions aiming to bring experts to collaborate in setting up virtual scenarios to increase the quality of life, safety perception, and risk awareness in people living in the proximity of a river. Floods are one of the most threatening climate events, and because of climate change, they are expected to become even more frequent. These disasters have a devastating impact on communities, increasing anxiety and stress levels in citizens living close to rivers. We involved relevant stakeholders to design “Safer Water,” an immersive, interactive, virtual experience to support citizens in psychologically and behaviorally managing pre and post riverbank breakdown situations. HCI experts, hydrogeological and hydraulic engineers, psychologists, and VEs designers took part in affinity diagram and brainstorming activities. Results show how the adopted method was able to generate suitable virtual scenarios, to highlight and classify relevant design requirements, and to find strategies that could improve the quality of life and psychological well-being in “risk-exposed citizens.” The discussion includes a set of open-access guidelines derived from the co-design activities, to support the design of VE for the purposes discussed in the paper.

Mitigating Psychological Impact: The Experience of Korean Disaster Management

The psychological impact of disasters has not been adequately addressed in Korea. This research aims to evaluate how Korea should improve its management of the psychological impact of disasters toward the ultimate goal of effective disaster management. Qualitative content analysis is the main method applied. Nonprofessional management is compared with professional management by considering governments, psychology specialists, disaster victims, and local communities. The main finding is that Korea must change its current management style from nonprofessional to professional. Neighboring nations need to implement supplementary measures toward adopting a systematic approach that considers all phases of the disaster management cycle, emergency planning, and a long-term approach. The value of this study lies in its comprehensive examination of the issue of psychological impact from the perspective of disaster management in Korea.

Learned Helplessness, Psychological Wellbeing, and Proenvironment Care Behavior among Victims of Frequent Floods in Kerala

Background  In 2018 and 2019, there were floods in the coastal regions of Kerala. Many individuals and families were victims on both these occasions; these floods had devastating impact on individual psychological wellbeing, their financial stability, and on overall family wellbeing. Furthermore, many people in vulnerable geographical areas still live in uncertainty and fear. In this context, our study examined whether continuous victimization of natural calamities, like floods in Kerala, leads to the development of learned helplessness and decreased psychological wellbeing among those affected. We also studied whether proenvironment care behavior increased among flood-affected individuals. Materials and Methods  We studied 374 heads of families in Kerala, selected through the Quota sampling method. They belonged to the following three groups: (1) flood-affected only once (OFA, n = 124), (2) flood-affected twice (TFA, n = 124), and (3) never flood-affected (NFA, n = 124) households. The key variables of learned helplessness, psychological wellbeing, and proenvironment care behavior were measured using learned helplessness scale, psychological wellbeing scale, and the environmental behavior scale, respectively. Statistical Analysis  The Kruskal-Wallis test was used to analyze the data for independent groups. Results  Learned helplessness was found to be high among the TFA group. Psychological wellbeing and proenvironment care behavior were high among the OFA group as compared with the TFA group. The NFA group had higher learned helplessness in comparison to the OFA group, and psychological wellbeing and proenvironment care behavior were low when compared with the TFA group. Conclusion  We conclude that surviving a moderate amount of risk is perhaps necessary for better psychological wellbeing and that too many or too few risks in life are detrimental to good psychological health. Immediate psychological support among victims of natural calamities and periodic examination of well-being and psychological interventions among people who are vulnerable for frequent victimization of natural calamities have to part of disaster management related to natural calamities.

At the Water's Edge: Coastal Settlement, Transformative Adaptation, and Well-Being in an Era of Dynamic Climate Risk

With accelerating climate change, US coastal communities are experiencing increased flood risk intensity, resulting from accelerated sea level rise and stronger storms. These conditions place pressure on municipalities and local residents to consider a range of new disaster risk reduction programs, climate resilience initiatives, and in some cases transformative adaptation strategies (e.g., managed retreat and relocation from highly vulnerable, low-elevation locations). Researchers have increasingly understood that these climate risks and adaptation actions have significant impacts on the quality of life, well-being, and mental health of urban coastal residents. We explore these relationships and define conditions under which adaptation practices will affect communities and residents. Specifically, we assess climate and environmental stressors, community change, and well-being by utilizing the growing climate change literature and the parallel social science literature on risk and hazards, environmental psychology, and urban geography work, heretofore not widely integrated into work on climate adaptation.

Stressed, anxious, and sick from the floods: A photovoice study of climate extremes, differentiated vulnerabilities, and health in Old Fadama, Accra, Ghana

Although there is a large and growing literature on anticipated climate change impacts on health, we know very little about the linkages between differentiated vulnerabilities to climate extremes and adverse physical and mental health outcomes. In this paper, we examine how recurrent flooding interacts with gendered vulnerability, social differentiation, and place-related historical and structural processes to produce unequal physical and mental health outcomes. We situated the study in Old Fadama, Ghana, using a Photovoice approach (n = 20) and theoretical concepts from political ecologies of health and feminist political ecology. Overall, the study revealed several adverse physical and mental health impacts of flooding, with vulnerability differentiated based particularly on gender and age, but also housing, class, and income. Our findings suggest the need for greater attentiveness to social differentiation in scholarship involving political ecologies of health. The paper builds on the health and place literature by linking the social and contextual to the medical.

Effect of Extreme Weather Events on Mental Health: A Narrative Synthesis and Meta-Analysis for the UK

Extreme weather events are increasing in frequency and severity as a consequence of climate change and pose a significant threat to population mental health. This is the case even in temperate regions such as the United Kingdom (UK) where flooding and heat waves are forecast to become more common. We conducted a systematic review to quantify the prevalence and describe the causes of common mental health problems in populations exposed to extreme weather events in the UK. We searched Web of Science, EMBASE and PsycINFO for studies that measured the prevalence of depression, anxiety, and post-traumatic stress disorder (PTSD) in populations exposed to extreme weather events in the UK, published up to 12 December 2019. We included 17 studies, four of which were included in meta-analyses to determine the point prevalence of common mental health problems in the period within 12 months following extreme weather events. The point prevalence was 19.8% for anxiety (k = 4; n = 1458; 95% CI 7.42 to 32.15), 21.35% for depression (k = 4; n = 1458; 95% CI 9.04 to 33.65) and 30.36% for PTSD (k = 4; n = 1359; 95% CI 11.68 to 49.05). Key factors that affected mental ill health in people exposed to flooding were water depth and absence of flood warnings. Displacement from home underscored the narratives associated with people's perceptions of the impact of flooding. The high prevalence of common mental health problems suggests that the prevention of mental ill health in populations at risk or exposed to extreme weather events should be a UK public health priority.

Predictors of child resilience in a community-based cohort facing flood as natural disaster

BACKGROUND

Natural disasters are unpredictable and uncontrollable events that usually induce significant level of stress and social disruption in afflicted individuals. The consequences are formidable, affecting lifetime health and economic prosperity. Among natural disasters, floods are the most common causes and tend to have the highest economic burden. The aim of this study was to examine factors associated with child resilience in the face of the natural disaster experienced by the city of Calgary, Alberta, Canada during its unprecedented flood of 2013.

METHODS

The current study was conducted in a community-based cohort situated in the city of Calgary. The participants were recruited out of the All Our Families longitudinal cohort within the Cummings School of Medicine at the University of Calgary. Of the total 1711 people contacted, 469 people consented and completed questionnaire. Of those 469 who consented to be part of the study, 467 were eligible to be included for analysis. A flood impact questionnaire was delivered 6 months after the 2013 flood in families whose children were an average of 3 years old. Mother reported questionnaires were used to assess child resilience. The study included maternal data on a range of factors including socio-demographic, history of mental health, relationship with the partner and social support. Child related data were also incorporated into the study, and variables included delivery mode, child sex, and child age at the time of disaster.

RESULTS

Child resilience was best predicted by mother's age and social support, and by child gender, the child's externalizing and internalizing behaviors and the Rothbart temperament scale: effortful control. Furthermore, this study revealed that children who were more exposed to the flood events, showed higher resilience compared to the children who were less or not exposed.

CONCLUSIONS

These findings highlight the risk and protective factors that predict child resilience and suggest that mother reported questionnaire are useful tools to assess child resilience amidst early life adversity.

Cross sectional analysis of depression amongst Australian rural business owners following cyclone-related flooding

Background

Flooding is an increasingly prevalent natural hazard worldwide and can have a profound impact on the mental health of those directly and indirectly affected. Little is known about the impact on business owners, who may be particularly vulnerable to the mental health complications of flooding given the additional economic stressors.

Methods

A large cross-sectional survey was conducted six months after severe flooding in the rural Northern Rivers region of New South Wales, Australia in 2017. The survey assessed demographics, probable depression (using the Patient Health Questionnaire-2), flood exposure, flood-related financial factors, prior flood exposure and support from various organisations. Logistic regression was used to identify predictors of probable depression in 653 of the 745 participants who identified as business owners.

Results

The prevalence of probable depression in our sample was 17.0%. A quarter (25.1%) of business owners whose business was flooded suffered from probable depression, compared to 12.4% of non-flooded business owners. The multivariable model for probable depression demonstrated elevated adjusted odds ratios (AOR) for business owners who had to evacuate their business (AOR = 2.11, 95% Confidence Interval (CI) 1.25-3.57) compared to those who did not evacuate. Insurance disputes/rejections were a strong predictor for probable depression (AOR = 3.76, CI 1.86-7.60). Those whose income was reduced due to the flood and had not returned to normal six months post-flood demonstrated an increased AOR for probable depression (AOR 2.53, CI 1.26-5.07) compared to those whose income had returned to normal. The univariable analysis found elevated crude odds ratios (OR) for the cumulative effect of multiple flood exposures and unmet support needs by the state government (OR = 2.74, CI 1.12-6.68). The majority of business owners felt their needs were not met by most organisations providing flood-related support.

Conclusion

The impact of flood exposure and flood-related financial factors on probable depression was highly significant for the business owner population. Furthermore, business owners felt under-supported by flood-related services. These findings highlight the vulnerability of exposed business owners and the need for increased support. Disaster planning programs in conjunction with system level changes such as infrastructure and education are vital for disaster preparedness.

Long-Lasting Effects of the 2013 Yolanda Typhoon on Overall Health of Mothers and Children

OBJECTIVES

Three years after the 2013 Yolanda Typhoon, this study sought to determine the factors associated with the stress of the affected mothers and the health of the children on Leyte island, and the preparedness of the community to mitigate future potential disasters.

METHODS

Three hundred mothers with children from 0 to 7 years old were selected through convenience sampling, structured interviews conducted using the Hurricane-Related Traumatic Experiences questionnaire and the PTSD (post-traumatic stress disorder) Checklist 5 (PCL5), and the children's weights and heights were measured.

RESULTS

The provisional PTSD prevalence was found to be 53.3% 3 y after Yolanda. The multiple regression analysis with multiple imputation for the missing values found that housing and childcare attitudes were significantly associated with preparedness.

CONCLUSIONS

This study concluded that living in multistoried houses was useful for disaster mitigation and that the caregiving responsibility for their children could be a disaster preparedness motivation for mothers.

Were the floods in the UK 2007 and Germany 2013 game-changers?

This paper examines recovery after major floods in the UK and Germany. It focuses on two areas that were badly hit by flooding: Catcliffe, near Sheffield in the UK, and Passau in Bavaria, Germany. It reports on surveys of residents and businesses in each place and on surveys of national flood experts in both countries. The two events were comparable in terms of impacts, levels of preparedness and government response and show similar patterns of speed and quality of recovery. In Germany, it took about 18 months for 90% or more of residents to get back to normal, while in the UK it took a year longer. This difference may be related to funding; in the UK, over 90% of funding came from household insurance while in Germany over 60% came from federal aid, which may have been quicker. In both countries, the economy had recovered to near normal within 12-18 months. The majority of people surveyed in both countries (74% in Germany and 67% in the UK) believe that their homes and businesses are as just as vulnerable now as they were before the respective floods. However, in the UK, half of the respondents thought their neighbourhood was safer and better prepared compared to only 11% in Germany. This may be because substantial progress has been made in improving protection in the UK in areas flooded in 2007. Both floods were considered to be 'game-changers' and resulted in a heightened awareness of flood risk, increased investment in flood defences and an increasing emphasis on citizens taking more responsibility for flood preparedness. However, the Environment Agency in the UK lacks powers to prevent development in flood-prone areas, in Germany there are issues of coordination across large catchments that cross state boundaries and the insurance sector could play a bigger role in 'building back better'. Many homes and businesses continue to be at risk from major floods and more progress needs to be made in making them more resilient. This article is part of the theme issue 'Urban flood resilience'.

Impact of repeat flooding on mental health and health-related quality of life: a cross-sectional analysis of the English National Study of Flooding and Health

OBJECTIVE

To assess the association between flooding/repeat flooding and: (1) psychological morbidity (anxiety, depression, post-traumatic stress disorder (PTSD)) and (2) health-related quality of life (HRQoL) at 6 months post-flooding.

DESIGN

Cross-sectional analysis of data from the English National Study of Flooding and Health.

SETTING

Cumbria, England.

PARTICIPANTS

Questionnaires were sent to 2500 residential addresses at 6 months post-flooding; 590 people responded.

OUTCOMES

Probable depression was assessed using the Patient Health Questionnaire, probable anxiety using the Generalised Anxiety Disorder scale and probable PTSD using the short-form PTSD checklist (PCL-6). HRQoL was assessed using the EQ-5D-5L. Mental health outcomes were analysed using logistic regression; HRQoL dimensions using ordinal regression; and summary index/Visual Analogue Scale scores using linear regression.

RESULTS

One hundred and nineteen participants had been flooded, over half of whom were experiencing a repeat flooding event (54%; n=64). Mental health outcomes were elevated among flooded compared with unaffected participants (adjusted OR for probable depression: 7.77, 95% CI: 1.51 to 40.13; anxiety: 4.16, 95% CI: 1.18 to 14.70; PTSD: 14.41, 95% CI: 3.91 to 53.13). The prevalence of depression was higher among repeat compared with single flooded participants, but this was not significant after adjustment. There was no difference in levels of anxiety or PTSD. Compared with unaffected participants, those flooded had lower EQ-5D-5L index scores (adjusted coefficient: -0.06, 95% CI: -0.12 to -0.01) and lower self-rated health scores (adjusted coefficient: -6.99, 95% CI: -11.96 to -2.02). There was, however, little difference in HRQoL overall between repeat and single flooded participants.

CONCLUSIONS

Interventions are needed to help minimise the impact of flooding on people's mental health and HRQoL.

Examining Associations Between Hurricane Sandy Exposure and Posttraumatic Stress Disorder by Community of Residence

Exposure to 2012's Hurricane Sandy differed by community across New York City and nearby Long Island, and the differential impact of exposure on mental health concerns must be studied to enhance resilience in vulnerable communities. We assessed the association between self-reported Hurricane Sandy exposure and subsequent posttraumatic stress disorder (PTSD) symptoms, obtained through validated questionnaires completed by residents of lower Manhattan (n = 1,134), Queens/Long Island (LI)/Staten Island (SI; n = 622), and the Rockaways (n = 1,011); mean assessment times were 7, 14, and 32 months post-Sandy, respectively. The median number of hurricane exposures was similar for all communities; however, Rockaways residents had a higher proportion of likely PTSD symptoms (18.8%) compared to lower Manhattan (8.0%) and Queens/LI/SI residents (5.8%). Regarding likely PTSD, there was significant interaction between total hurricane exposure and community, p = .002, and flooding and community, p = .040. Number of hurricane exposures was associated with higher odds of likely PTSD in Queens/LI/SI, AOR = 1.61, 95% CI [1.34, 1.94]; lower Manhattan, AOR = 1.43, 95% CI [1.28, 1.59]; and the Rockaways, AOR = 1.25, 95% CI [1.16, 1.35]. Flooding was associated with increased odds of likely PTSD in the Rockaways, AOR = 1.65, 95% CI [1.01, 2.69]; and Queens/LI/SI, AOR = 3.29, 95% CI [1.08, 10.00]. This study emphasizes the differential impact of hurricane exposure on subsequent PTSD symptoms in three communities affected by Hurricane Sandy. Future preparedness and recovery efforts must understand community correlates of mental health concerns to promote resilience in vulnerable communities.

Psychiatric morbidity in December 2015 flood-affected population in Tamil Nadu, India

BACKGROUND

Floods are the most common type of natural disaster, which have a negative impact on mental health. Following floods, survivors are vulnerable to develop PTSD (post-traumatic stress disorder), depression, anxiety and other mental health problems.

AIM

The aim is to study the psychiatric morbidity in the persons affected by floods during December 2015.

MATERIALS AND METHODS

This study was carried out in Chennai and Cuddalore. In total, 223 persons who were directly exposed to floods were assessed. PTSD Checklist-Civilian Version, Beck's Depression Inventory, Beck's Anxiety Inventory and World Health Organization-Five Well-Being Scale (WHO-5) were used in the study. Chi-square test was used to compare the means.

RESULTS

Overall, psychiatric morbidity was found to be 45.29%; 60 (26.9%) persons had symptoms of PTSD. Anxiety was found in 48 (27.4%) and depression was found in 101 (45.29%) persons; and 11 (4.9%) persons have reported an increase in substance abuse.

CONCLUSION

Following disaster like floods, there is a need for better preparedness in terms of basic necessities and medical and psychological assistance, particularly emphasizing the needs of older persons in order to prevent the development of psychiatric problems.

Post-Traumatic Stress Disorder among the Flood Affected Population in Indian Subcontinent

Globally, frequent flooding causes higher magnitude of disaster among the developing and developed nations. Particularly, the Indian subcontinent is considered as highly vulnerable area for natural disaster and is affected most because of limited resources and coping strategies for post-disaster rehabilitation. Apart from the great impact on human health, floods have considerable impact on mental health. The most frequently diagnosed psychological illness in flood affected population is post-traumatic stress disorder (PTSD). In India, the incidence of PTSD in major natural disasters varies considerably depending upon the magnitude of event, with the highest rates reported of around 70%. Studies conducted during initial few months post-disaster, showed a higher occurrence of psychiatric manifestations. On the other hand, some reports suggested contrary results under similar circumstances. Notably, extreme age (children and elderly), female gender, socioeconomic status, pre-existing mental health issues and financial crisis post-disaster are the potential predisposing factors influencing the vulnerability of PTSD. In Indian context, the variability in the magnitude of psychiatric illness is mainly attributed to the ethnic diversity (vulnerable population), severity and type of flood event and social support. Still there is more to explore regarding the long-term sequelae of catastrophic floods on physical and mental trauma on disaster-affected populations.

Posttraumatic Growth and Trauma in Flood Survivors: Contributions of Attitudes Toward God

Natural disasters, including floods, affect entire communities and often lead survivors to report symptoms of posttraumatic stress (PTS). Although the vast majority of disaster research focuses on negative emotional outcomes, individuals may simultaneously experience positive outcomes such as posttraumatic growth (PTG). This study examined the influence of attitudes toward God (i.e., positive attitudes toward God and disappointment/anger with God) on perceived PTG and PTS following the 2016 floods in Baton Rouge, Louisiana (N = 416). Hierarchical regressions revealed that flood exposure and attitudes toward God predicted perceived PTG and PTS. In addition, disappointment/anger with God helped to moderate the relationship between flood exposure and perceived PTG in flood survivors. Findings underscore the role that counselors can play in facilitating growth in disaster survivors and in processing spiritual topics with clients when relevant.

Perception of Urban Environmental Risks and the Effects of Urban Green Infrastructures (UGIs) on Human Well-being in Four Public Green Spaces of Guangzhou, China

Cities face many challenging environmental problems that affect human well-being. Environmental risks can be reduced by Urban Green Infrastructures (UGIs). The effects of UGIs on the urban environment have been widely studied, but less attention has been given to the public perception of these effects. This paper presents the results of a study in Guangzhou, China, on UGI users' perceptions of these effects and their relationship with sociodemographic variables. A questionnaire survey was conducted in four public green spaces. Descriptive statistics, a binary logistic regression model and cross-tabulation analysis were applied on the data from 396 valid questionnaires. The results show that UGI users were more concerned about poor air quality and high temperature than about flooding events. Their awareness of environmental risks was partly in accordance with official records. Regarding the perception of the impacts of environmental risks on human well-being, elderly and female respondents with higher education levels were the most sensitive to these impacts. The respondents' perceptions of these impacts differed among the different green spaces. The effects of UGIs were well perceived and directly observed by the UGI users, but were not significantly influenced by most sociodemographic variables. Moreover, tourists had a lower perception of the impacts of environmental risks and the effects of UGI than residents did. This study provides strong support for UGIs as an effective tool to mitigate environmental risks. Local governments should consider the role of UGIs in environmental risk mitigation and human well-being with regard to urban planning and policy making.

The long-term physical and psychological health impacts of flooding: A systematic mapping

BACKGROUND

Flooding has caused significant and wide ranging long-term health impacts for affected populations. However, until now, the long-term health outcomes, epidemiological trends and specific impact factors of flooding had not been identified. In this study, the relevant literature was systematically mapped to create the first synthesis of the evidence of the long-term health impacts of flooding.

METHODS

The systematic mapping method was used to collect and categorize all the relevant literature. A study was included if it had a description or measurement of health impacts over six months after flooding. The search was limited to peer reviewed articles and grey literature written in English, published from 1996 to 2016.

RESULTS

A total of 56 critical articles were extracted for the final map, including 5 qualitative and 51 quantitative studies. Most long-term studies investigated the psychological impacts of flooding, including PTSD, depression, anxiety, psychiatric disorders, sleep disorder and suicide. Others investigated the physiological impacts, including health-related quality of life, acute myocardial infarction, chronic diseases, and malnutrition. Social support was proved to be protective factors that can improve health outcomes in the long-term after flooding. To date, there have been relatively few reviews had focused on the long-term health impacts of flooding. This study coded and catalogued the existing evidence across a wide range of variables and described the long-term health consequences within a conceptual map.

DISCUSSION AND CONCLUSIONS

Although there was no boundary between the short-term and the long-term impacts of flooding, the identified health outcomes in this systematic mapping could be used to define long-term health impacts. The studies showed that the prevalence of psychological diseases had a reversed increasing trend occurred even in the long-term in relatively poor post-flooding environments. Further cohort or longitudinal research focused on disability, chronic diseases, relocation population, and social interventions after flooding, are urgently required.

PTSD and depression in adult survivors of flood fury in Kashmir: The payoffs of social support

Exposure to disasters such as floods predisposes individuals for psychological distress such as posttraumatic stress disorder (PTSD), depression, and anxiety. Researchers exploring the association between flood-exposure and psychopathology attempt to understand the conditions and mechanisms through which potential benefits may occur. One such potential factor that may contribute to resilience in the face of disaster is social support system. However, there is scarcity of researches concerning the protective effects of social support following floods, in adult samples. Thus, the present study examined the moderating and indirect effects of perceived social support from family and friends in the association between flood-exposure and symptoms of PTSD and depression. The study was a cross sectional in nature. Survey data were collected from 87 adult survivors of flood fury in Kashmir valley, aged 30-40. High level of family and friends' support reduced the association between flood-exposure and symptoms of PTSD and depression whereas a low level of such support enhanced this association. Results also suggested that family support carried a significant proportion of variance in predicting depression. Given the potential for negative mental health outcomes following natural disasters, efforts to enhance adults' social support may be especially important.

Health impacts of climate change and health and social inequalities in the UK

This article examines how social and health inequalities shape the health impacts of climate change in the UK, and what the implications are for climate change adaptation and health care provision. The evidence generated by the other articles of the special issue were interpreted using social justice reasoning in light of additional literature, to draw out the key implications of health and social inequalities for health outcomes of climate change. Exposure to heat and cold, air pollution, pollen, food safety risks, disruptions to access to and functioning of health services and facilities, emerging infections and flooding are examined as the key impacts of climate change influencing health outcomes. Age, pre-existing medical conditions and social deprivation are found to be the key (but not only) factors that make people vulnerable and to experience more adverse health outcomes related to climate change impacts. In the future, climate change, aging population and decreasing public spending on health and social care may aggravate inequality of health outcomes related to climate change. Health education and public preparedness measures that take into account differential exposure, sensitivity and adaptive capacity of different groups help address health and social inequalities to do with climate change. Adaptation strategies based on individual preparedness, action and behaviour change may aggravate health and social inequalities due to their selective uptake, unless they are coupled with broad public information campaigns and financial support for undertaking adaptive measures.

Mental health impacts of flooding: a controlled interrupted time series analysis of prescribing data in England

BACKGROUND

There is emerging evidence that people affected by flooding suffer adverse impacts on their mental well-being, mostly based on self-reports.

METHODS

We examined prescription records for drugs used in the management of common mental disorder among primary care practices located in the vicinity of recent large flood events in England, 2011-2014. A controlled interrupted time series analysis was conducted of the number of prescribing items for antidepressant drugs in the year before and after the flood onset. Pre-post changes were compared by distance of the practice from the inundated boundaries among 930 practices located within 10 km of a flood.

RESULTS

After control for deprivation and population density, there was an increase of 0.59% (95% CI 0.24 to 0.94) prescriptions in the postflood year among practices located within 1 km of a flood over and above the change observed in the furthest distance band. The increase was greater in more deprived areas.

CONCLUSIONS

This study suggests an increase in prescribed antidepressant drugs in the year after flooding in primary care practices close to recent major floods in England. The degree to which the increase is actually concentrated in those flooded can only be determined by more detailed linkage studies.

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).

Effect of evacuation and displacement on the association between flooding and mental health outcomes: a cross-sectional analysis of UK survey data

BACKGROUND

Extensive flooding occurred during the winter of 2013-14 in England. Previous studies have shown that flooding affects mental health. Using data from the 2013-14 Public Health England National Study of Flooding and Health, we compared the prevalence of symptoms of depression, anxiety, and post-traumatic stress disorder between participants displaced by flooding and those flooded, but not displaced, 1 year after flooding.

METHODS

In this multivariable ordinal regression analysis, we collected data from a cross-sectional survey collected 1 year after the flooding event from flood-affected postcodes in five counties in England. The analysis was restricted to individuals whose homes were flooded (n=622) to analyse displacement due to flooding. The primary outcome measures were depression (measured by the PHQ-2 depression scale) and anxiety (measured by the two-item Generalised Anxiety Disorder [GAD]-2 anxiety scale), and post-traumatic stress disorder (measured by the Post-Traumatic Stress Disorder Checklist [PCL]-6 scale). We adjusted analyses for recorded potential confounders. We also analysed duration of displacement and amount of warning received.

FINDINGS

People who were displaced from their homes were significantly more likely to have higher scores on each scale; odds ratio (OR) for depression 1·95 (95% CI 1·30-2·93), for anxiety 1·66 (1·12-2·46), and for post-traumatic stress disorder 1·70 (1·17-2·48) than people who were not displaced. The increased risk of depression was significant even after adjustment for severity of flooding. Scores for depression and post-traumatic stress disorder were higher in people who were displaced and reported receiving no warning than those who had received a warning more than 12 h in advance of flooding (p=0·04 for depression, p=0·01 for post-traumatic stress disorder), although the difference in anxiety scores was not significant.

INTERPRETATION

Displacement after flooding was associated with higher reported symptoms of depression, anxiety, and post-traumatic stress disorder 1 year after flooding. The amount of warning received showed evidence of being protective against symptoms of the three mental illnesses studied, and the severity of flooding might be the reason for some, but not all, of the differences between the groups.

Self-Reported and FEMA Flood Exposure Assessment after Hurricane Sandy: Association with Mental Health Outcomes

Hurricane Sandy caused extensive physical and economic damage; the long-term mental health consequences are unknown. Flooding is a central component of hurricane exposure, influencing mental health through multiple pathways that unfold over months after flooding recedes. Here we assess the concordance in self-reported and Federal Emergency Management (FEMA) flood exposure after Hurricane Sandy and determine the associations between flooding and anxiety, depression, and post-traumatic stress disorder (PTSD). Self-reported flood data and mental health symptoms were obtained through validated questionnaires from New York City and Long Island residents (N = 1231) following Sandy. Self-reported flood data was compared to FEMA data obtained from the FEMA Modeling Task Force Hurricane Sandy Impact Analysis. Multivariable logistic regressions were performed to determine the relationship between flooding exposure and mental health outcomes. There were significant discrepancies between self-reported and FEMA flood exposure data. Self-reported dichotomous flooding was positively associated with anxiety (ORadj: 1.5 [95% CI: 1.1-1.9]), depression (ORadj: 1.7 [1.3-2.2]), and PTSD (ORadj: 2.5 [1.8-3.4]), while self-reported continuous flooding was associated with depression (ORadj: 1.1 [1.01-1.12]) and PTSD (ORadj: 1.2 [1.1-1.2]). Models with FEMA dichotomous flooding (ORadj: 2.1 [1.5-2.8]) or FEMA continuous flooding (ORadj: 1.1 [1.1-1.2]) were only significantly associated with PTSD. Associations between mental health and flooding vary according to type of flood exposure measure utilized. Future hurricane preparedness and recovery efforts must integrate micro and macro-level flood exposures in order to accurately determine flood exposure risk during storms and realize the long-term importance of flooding on these three mental health symptoms.
