Posttraumatic Stress Disorder after Hurricane Sandy among Persons Exposed to the 9/11 Disaster

Meta-Analysis on the Health Effects Resulting from Evacuation or Relocation

OBJECTIVE

Evacuation and relocation are key actions used to protect the public in response to natural or technological disasters, but there are inherent risks to both. Unfortunately, these risks have not been fully quantified, which limits the ability of emergency managers and the public to effectively balance the risks and benefits of evacuation or relocation. This work provides quantitative data on the risks of health effects from displacement following evacuation or relocation.

METHODS

Researchers performed a literature review and meta-analysis of published studies and quantified risks of 14 different health effects, including both physical and socio-behavioral outcomes, from studies of 9 different disaster types.

RESULTS

The findings show statistically significant increases in 9 of the 14 health effects in displaced populations, indicating an increased likelihood of experiencing detrimental health effects compared with nondisplaced populations. A pooled analysis of all negative health effects found an odds ratio of 1.49 (95% confidence interval: 1.24-1.79), which shows a significant relationship between displacement and negative health outcomes.

CONCLUSIONS

These findings demonstrate that evacuated or relocated populations have an increased risk of experiencing negative health effects associated with displacement. The broad number of disaster types included mean that findings are applicable to any emergency evacuation or relocation.

Investigating the Health Impacts of Climate Change among People with Pre-Existing Mental Health Problems: A Scoping Review

Climate change is the greatest threat to global public health, although the impacts on mental health are relatively understudied. Furthermore, there is a lack of consensus about the effects of climate change on individuals with pre-existing mental health problems. This review aimed to identify the health impacts of climate change on people with pre-existing mental health problems. The search was conducted across three databases; studies were included if they involved participants who had mental health problem(s) before a climate-driven event and reported on health outcomes post-event. A total of thirty-one studies met the full inclusion criteria. The study characteristics included 6 climate-driven events: heat events, floods, wildfires, wildfire and flood, hurricanes, and droughts, and 16 categories of pre-existing mental health problems, with depression, and non-specified mental health problems being the most common. The majority of the studies (90%, n = 28) suggest an association between the presence of pre-existing mental health problems and the likelihood of adverse health impacts (e.g., increased mortality risk, new symptom presentation, and an exacerbation of symptoms). To mitigate the exacerbation of health inequalities, people with pre-existing mental health problems should be included in adaption guidance and/or plans that mitigate the health impacts of climate change, future policy, reports, and frameworks.

Adding fuel to the fire? Examining exposure to potentially stressful or traumatic events before and during the COVID-19 pandemic in low-income, Black families

OBJECTIVE

The COVID-19 pandemic has upended the lives of many individuals. While emerging evidence has begun to document health (e.g., infection) and financial (e.g., job loss) consequences, less is known about the day-to-day experiences of some of the country's most vulnerable populations. The current study sought to address this gap in understanding by examining exposure to potentially stressful or traumatic experiences (PSTEs) and their relation to mental health among predominately low-income, African American/Black individuals.

METHOD

Adult caregivers (N = 110) from an ongoing longitudinal research project occurring prior the pandemic completed surveys about their exposure to COVID-19-specific PSTEs during the initial months of the pandemic. Information on participants was combined with pre-COVID-19 PSTE exposure and examined in relation to current mental health functioning (e.g., depression).

RESULTS

Findings indicated that participants experienced several different types of COVID-19-specific PSTEs across multiple domains, including home, work, social life, and health and well-being. Results from model testing indicated that COVID-19-specific PSTEs were only associated with worry about COVID-19-specifically. Adulthood PSTEs prior to COVID-19 were also associated with current anxiety symptoms.

CONCLUSIONS

Among low-income, African American/Black individuals with a history of exposure to PSTEs, additional PSTEs experienced during the COVID-19 pandemic may not contribute significantly to general mental health functioning above and beyond pre-COVID-19 PSTE exposures. Taken together, research on PSTE exposure from the pandemic should make attempts to account for lifetime PSTE exposure to most accurately evaluate current mental health concerns, especially among marginalized populations.

Economic and mental health impacts of multiple adverse events: Hurricane Harvey, other flooding events, and the COVID-19 pandemic

OBJECTIVES

To assess the economic and mental health impacts of COVID-19 in the presence of previous exposure to flooding events.

METHODS

Starting in April 2018, the Texas Flood Registry (TFR) invited residents to complete an online survey regarding their experiences with Hurricane Harvey and subsequent flooding events. Starting in April 2020, participants nationwide were invited to complete a brief online survey on their experiences during the pandemic. This study includes participants in the TFR (N = 20,754) and the COVID-19 Registry (N = 8568) through October 2020 (joint N = 2929). Logistic regression and generalized estimating equations were used to examine the relationship between exposure to flooding events and the economic and mental health impacts of COVID-19.

RESULTS

Among COVID-19 registrants, 21% experienced moderate to severe anxiety during the pandemic, and 7% and 12% of households had difficulty paying rent and bills, respectively. Approximately 17% of Black and 15% of Hispanic households had difficulty paying rent, compared to 5% of non-Hispanic white households. The odds of COVID-19 income loss are 1.20 (1.02, 1.40) times higher for those who previously had storm-related home damage compared to those who did not and 3.84 (3.25-4.55) times higher for those who experienced Harvey income loss compared to those who did not. For registrants for whom Harvey was a severe impact event, the odds of having more severe anxiety during the pandemic are 5.14 (4.02, 6.58) times higher than among registrants for whom Harvey was a no meaningful impact event.

CONCLUSIONS

Multiple crises can jointly and cumulatively shape health and wellbeing outcomes. This knowledge can help craft emergency preparation and intervention programs.

Self-Efficacy and Mental Health Help-Seeking Behavior of World Trade Center Health Registry Enrollees, 2015-2016

The September 11th World Trade Center (WTC) disaster resulted in an elevated prevalence of Post-Traumatic Stress Disorder (PTSD) among those directly exposed, yet lower than expected rates of mental health treatment seeking and high levels of reported perceived unmet mental healthcare need were observed in this population in the years following. Self-efficacy, an individual's self-perception of their ability to succeed in specific situations or accomplish a task or goal, may in part explain this discrepancy; however, little is known about its interplay with the help-seeking behaviors of disaster-exposed populations. We used WTC Health Registry data (n = 11,851) to describe the relationship between self-efficacy and three outcomes related to help-seeking behavior: (1) seeking mental health treatment, (2) perceived unmet mental health care needs, and (3) satisfaction with mental health treatment. Multinomial logistic regression models were used to estimate adjusted odds ratios (AORs) and 95% confidence intervals (CI). We found a dose-response relationship between self-efficacy score and mental health help-seeking: for every one unit increase in self-efficacy score, we observed a 6% increase in the odds of having treatment 4 to 12 months ago (OR = 1.06, CI: 1.03-1.09), a 7% increase in the odds of having had treatment 1 to 2 years ago (OR = 1.07, CI: 1.04, 1.09), and a 10% increase in the odds of having sought treatment 2 or more years ago (OR = 1.10, CI: 1.08, 1.12) compared to those who had sought treatment more recently. An understanding of individual self-efficacy may help improve post-disaster mental health treatment in order to provide more tailored and helpful care.

Change in 9/11-related post-traumatic stress symptoms following cancer diagnosis

OBJECTIVE

Cancer can be a life-threatening stressor that may evoke pre-existing post-traumatic stress disorder (PTSD). We assessed change in 9/11-related PTSD symptoms following cancer diagnosis in a 9/11-exposed cohort, the World Trade Center Health Registry.

METHODS

We examined enrollees who had a first-time post-9/11 invasive cancer diagnosis and at least one pre- and two post-diagnosis 9/11-related PTSD assessments from enrolment through 2015. PTSD symptoms were measured using 17-item PTSD Checklist (PCL, range 17-85). Cancer was identified from New York State Cancer Registry and categorized as localized or advanced stage. We used piecewise spline linear mixed-effects models to examine rate of change in PCL scores from pre- to post-diagnosis periods, and whether the change differed by gender or stage, with time as fixed and random effects, adjusting for baseline age, race, and education.

RESULTS

9/11-related PTSD symptoms were slightly increasing in the pre-diagnosis period, while this trend reversed in the post-diagnosis period (β: -0.38; 95% CI: -0.60, -0.15). This trend was driven by male rescue/recovery workers (RRW), among whom significant decrease in rate of change in PCL scores was observed for those with advanced stage (slope change difference [95% CI]: -1.81 [-2.73, -0.90]). No significant difference in rate of change was observed among non-RRW. Among females, PCL scores tended to decrease slightly, with no significant difference in rate of change between pre- and post-diagnosis periods.

CONCLUSIONS

We observed significant reduction in the rate of change in 9/11-related PTSD symptoms among male RRW. The underlying mechanism is unknown, necessitating future research.

Increased risk of multiple pregnancy complications following large-scale power outages during Hurricane Sandy in New York State

BACKGROUND

Large-scale power outages (PO) are increasing in the context of climate change. Although some research has been conducted into the adverse health impacts of POs, significant gaps remain regarding whether POs would affect the health of pregnant women. We investigated the association between ED visits due to pregnancy complications and the occurence, intensity, and duration of large-scale POs in eight Sandy-affected counties in New York State (NYS).

METHODS

In this cross-sectional study, daily ED visits for pregnancy complications and large-scale PO data in eight counties in NYS from October to December in 2005-2014 were collected. Using time-series analysis, we estimated the relative increase in ED visits for pregnancy complications during POs compared with non-PO periods at lag 0-7 days. Short-term health impacts of PO intensity and PO duration were investigated. Estimations were also stratified by sociodemographic characteristics and disease subtypes including threatened or spontaneous abortion, threatened or early labor, hypertension complications, infections of genitourinary tract, renal diseases, gestational diabetes mellitus, mental illnesses, and cardiovascular diseases during pregnancy.

RESULTS

From October to December in 2005-2014, there were 307,739 ED visits for pregnancy complications in the eight counties. We found significant increases in ED visits for overall pregnancy complications (16.6%, 95% confidence interval [CI]: 10.3%, 23.2%) during the Hurricane-PO period at lag 0-7 days. The ED visits increased by 8.8% per level increase in PO intensity and 1.4% per day increase in PO duration. Specifically, threatened/early delivery and gestational diabetes mellitus during the PO period increased by 26.7% (95% CI: 8.2%, 48.4%) and 111.8% (95% CI: 16.7%, 284.4%), respectively. Young adult, Black, Hispanic, and uninsured individuals were at higher risk of complications.

CONCLUSIONS

POs may adversely impact pregnancy, especially for certain pregnancy complications and among low sociodemographic women.

A Mixed-Methods Study After Multiple Disasters: September 11, 2001, World Trade Center Terrorist Attacks and Hurricane Sandy

OBJECTIVE

The aim of this study was to use a mixed-method analysis to investigate the associations between qualitative themes found in written responses and quantitative reported level of stress after Hurricane Sandy.

METHODS

A survey was conducted among World Trade Center Health Registry enrollees 5-12 mo after Hurricane Sandy. This study included 1202 participants who completed the free-response section and answered the question on how stressful their experiences were with Hurricane Sandy and its aftermath. Content analysis was used to generate qualitative data. Mixed-methods analysis was performed using a 1-way analysis of variance test for bivariate comparisons of qualitative thematic codes and the quantitative outcome of mean Sandy stress scores.

RESULTS

Seven themes emerged from the qualitative analysis. The themes of lack of information, negative emotional response, and financial stress had higher quantitative mean Sandy stress scores compared with other themes. The theme of patriotism/gratitude had an overall lower quantitative Sandy stress scores than other themes.

CONCLUSIONS

Qualitative and mixed-methods research on mental health outcomes after a disaster add new depth and findings to the existing literature. Using such methodologies to identify modifiable factors, such as improving communication during a disaster, may confer better mental health outcomes after a disaster.

Exposure to Hurricane Sandy and Risk of Opioid Abuse

BACKGROUND

Given both the increased prevalence of natural disasters in recent years and the crippling opioid epidemic, identifying at-risk groups for substance abuse post-disaster is imperative to survivor mental health. The objective of this study was to examine the association between exposure to Hurricane Sandy and risk of opioid abusive behavior.

METHODS

We conducted a retrospective analysis using data from two cross-sectional studies that examined the impact of Hurricane Sandy on mental health from October 2013- August 2016. Patient demographics, hurricane exposure and mental health history were obtained via self-report questionnaires. Opioid abuse risk was determined and categorized using adaptations from the Opioid Risk Tool (ORT). Multinomial logistic regression was used to examine the relationship between hurricane exposure and opioid abuse risk.

RESULTS

Data was available on 1,687 Hurricane Sandy survivors, the majority being female (59.3%), white (52.0%) and an average age of 46.1 years (std. 19.2). Approximately 9.0% of survivors were classified as being 'High' risk for opioid abuse. For every increase in total exposure reported, the odds of being classified as high risk was 1.09 greater (95% CI 1.05, 1.14) compared to low risk, after adjusting for covariates. Among personal exposures only (i.e. injury to self or family member), for every increase in reported exposure the adjusted odds of being classified as high risk was 1.25 times greater (95% CI 1.15, 1.37) compared to low risk.

CONCLUSIONS

These findings suggest that exposure to a natural disaster, specifically personal exposures, are associated with increased risk for opioid abusive behavior.

The disaster worker resiliency training program: a randomized clinical trial

OBJECTIVES

Disaster workers are at elevated risk for mental health problems as a result of trauma exposures during response efforts. One possible way to prevent mental health problems is to build-up coping resources that promote resilience to the effects of disaster work. The primary aim of this study was to evaluate the efficacy of a resilience building workshop, the Disaster Worker Resiliency Training Program (DWRT), in disaster workers previously exposed to Hurricane Sandy.

METHODS

Disaster workers (N = 167) were randomly assigned to the DWRT workshop (n = 78) or a waitlist (n = 89). Workers completed self-report measures on healthy lifestyle behaviors, perceived stress, depression, and Posttraumatic Stress Disorder (PTSD) symptoms at baseline and 3-month follow-up. They also completed a measure assessing subsequent trauma-exposure between the baseline and 3-month post-intervention.

RESULTS

Participants in the workshop condition, as compared to those in a waitlist control, reported significantly greater improvements from pre-intervention (T1) to 3-month follow-up (T2) in healthy lifestyle behaviors (η2 = .03; p = .03), stress management (η2 = .03, p = .04), and spiritual growth (η2 = .03, p = .02). Among participants reporting subsequent trauma exposures between T1 and T2  (n = 101), participants in the waitlist condition, were more likely to report significant increases in perceived stress (η2 = .07, p < .01), PTSD (η2 = .05, p = .03), and depression (η2 = .07, p < .01) symptoms.

CONCLUSIONS

Participation in the resilience workshop promoted engagement in positive health behaviors and reduced the incidence of mental health symptoms, especially when administered prior to a repeat trauma exposure. Further research is needed to evaluate the long-term health effects of participation in the program.

Anxiety and resilience in the face of natural disasters associated with climate change: A review and methodological critique

In the past two decades, climate change-related natural disasters, such as hurricanes, floods, and droughts have become increasingly frequent and severe, impacting the emotional and psychological well-being of those who are directly or indirectly exposed to them. Despite great interest in understanding differences in anxiety and resilience in response to natural disasters, enthusiasm appears to outstrip empirical clarity, as there remains considerable ambiguity as to determinants of resilient or pathological outcomes following exposure to natural disasters. In addition, there are several major methodological limitations in climate change and related natural disaster research, including the use of univariate analyses, cross-sectional design, and retrospective measures. Keeping these limitations in mind, we first review literature examining the mental health outcomes of natural disasters. Findings suggest that, overall, resilience is more common than pathological outcomes. Second, we use a multi-dimensional framework of resilience to selectively review factors at the event, individual, as well as family and community levels that could help inform resilient or pathological outcomes. Finally, we consider key limitations and future directions for research and practice in the field of anxiety and resilience in response to climate disasters.

Change in binge drinking behavior after Hurricane Sandy among persons exposed to the 9/11 World Trade Center disaster

•

4.7% participants were new binge drinkers after Hurricane Sandy.

•

Persons with high Sandy exposure were more likely to be new/consistent binge drinkers.

•

Among persons without 9/11 PTSD, Sandy PTSD was associated with new binge drinking.

•

High Sandy exposure, and Sandy PTSD were associated with higher binge intensity after Sandy.

•

Response to future disasters should address alcohol use and PTSD simultaneously.

The objective of this study was to examine changes in drinking behavior after Hurricane Sandy among 3199 World Trade Center Health Registry (Registry) enrollees before (2011–12) and after Hurricane Sandy (2015–16). A composite Sandy exposure scale (none, low, medium and high) included Sandy traumatic experiences, financial and other factors. Probable Sandy-related posttraumatic stress disorder (PTSD) was defined as scoring ≥44 on PTSD Checklist, and binge drinking as consuming ≥5 alcoholic drinks for men or ≥4 for women on one occasion in the past 30 days. Some of the enrollees reported binge drinking post Sandy as new binge drinkers (4.7%) or consistent binge drinkers pre- and post-Sandy (19%). Compared with non-binge drinkers pre- and post-Sandy (66.9%), the adjusted odds ratios (aOR) for being new binge drinkers and consistent binge drinkers among high Sandy exposure enrollees were 2.1 (95%CI 1.1–4.1) and 2.5 (95%CI: 1.7–3.6), respectively. High Sandy traumatic experience alone was associated with consistent binge drinking (aOR: 1.9, 95%CI: 1.4–2.6). Among enrollees without 9/11 PTSD, those with Sandy PTSD were more likely to become new binge drinkers (aOR: 4.4, 95%CI: 1.4–13.9), while Sandy PTSD was not associated with any binge drinking behavior changes among those with 9/11 PTSD. Sandy exposure, Sandy traumatic experience, and Sandy PTSD were all associated with higher binge drinking intensity. Future natural disaster response should plan for treatment to address alcohol use and PTSD simultaneously.

The Intentional Self-Medication of 9/11-Related PTSD Symptoms with Alcohol: 15 Years after the Disaster

The self-medication hypothesis may explain the co-morbidity of affective and substance use disorders. Research shows increased prevalence, frequency, and intensity of binge drinking and post-traumatic stress disorder (PTSD) among those directly exposed to the 9/11 terrorist attacks on the World Trade Center (WTC), however, little is known about PTSD symptomology and intentional self-medication with alcohol (ISMA) among this group. We used WTC Health Registry data (N = 28,935) to describe the relationship between ISMA and specific symptom clusters of probable 9/11-related PTSD, the number of PTSD symptom clusters endorsed, and binge drinking intensity. Multivariable logistic regression models were used to estimate the adjusted odds ratios (AORs) and 95% confidence intervals (CI). ISMA was most strongly associated with the hyperarousal PTSD symptom cluster (AOR = 2.04 [1.88, 2.21]) and the endorsement of one (AOR = 1.80 CI [1.65, 1.95]), two (AOR = 2.51 CI [2.28, 2.77]), or three (AOR = 2.84 CI [2.55, 3.17]) PTSD symptom clusters, indicating a clear dose–response relationship. A significant number of 9/11-exposed persons continue to experience PTSD symptoms and engage in ISMA as a potential coping mechanism. Repeated screenings for self-medicative alcohol use among survivors of mass traumas with PTSD symptoms is of public health importance.

Injury Severity and Psychological Distress Sustained in the Aftermath of the Attacks of 11 September 2001 Predict Somatic Symptoms in World Trade Center Health Registry Enrollees Sixteen Years Later

The World Trade Center attacks of 11 September 2001 (9/11) have been associated with the subsequent development of chronic diseases. Few studies have investigated the burden of somatic symptoms on attack victims, or the association of such symptoms with exposure to the 9/11 attacks. World Trade Center Health Registry (Registry) enrollees who were present south of Chambers Street during or immediately after the 9/11 attacks and who provided consistent answers regarding injury sustained on 9/11 were followed prospectively for up to 16 years post-9/11/01. We employed linear regression to evaluate the associations between injury severity, psychological distress and somatic symptoms in 2322 persons who completed all four Registry surveys and a subsequent Health and Quality of Life survey. Twenty-one percent of subjects had a “very high” burden of somatic symptoms, greater than in populations not exposed to a disaster. Somatic symptoms exhibited a dose-response association separately with injury severity and psychological distress trajectories. Victims of the 9/11 attacks suffer from a substantial burden of somatic symptoms which are associated with physical and psychological consequences of exposure to the attacks. Physical and mental health professionals need to work together when treating those exposed to complex disasters such as 9/11.

Differential effect of Hurricane Sandy exposure on PTSD symptom severity: comparison of community members and responders

OBJECTIVES

To evaluate whether the association between Hurricane Sandy exposures and post-traumatic stress disorder (PTSD) symptom severity was greater for exposed community members compared with responders.

METHODS

Data were analysed from three existing studies with similar methodologies (N=1648): two community studies, Leaders in Gathering Hope Together (n=531) and Project Restoration (n=763); and the Sandy/World Trade Center Responders Study (n=354). Sandy-related PTSD symptoms were measured using the PTSD checklist-specific traumatic event and dichotomised as elevated (>30) versus low/no (<30) PTSD symptoms. Sandy exposures were measured with a summed checklist. Multivariable logistic regression was performed to evaluate the differential effect of exposures on PTSD by responder status, adjusting for demographics and time elapsed since Sandy.

RESULTS

Responders were somewhat older (50.5 years (SD=8.3) vs 45.8 years (SD=20.0)), more likely to identify as white (92.4% vs 48.1%) and were male (90.7% vs 38.4%). Responders were less likely to have elevated PTSD symptoms than community members (8.6% vs 31.1%; adjusted OR=0.28, 95% CI 0.17 to 0.46). While exposure was significantly related to elevated PTSD status, the effects were similar for responders and community members.

CONCLUSIONS

Responders appear to be more resilient to PTSD symptoms post-Sandy than community members. Understanding the mechanisms that foster such resilience can inform interventions aimed at populations that are more vulnerable to experiencing PTSD after natural disasters.

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.

The trajectory of symptom burden in exposed and unexposed survivors of a major avalanche disaster: a 30 year long-term follow-up study

BACKGROUND

Limited research exists concerning the long-term effects of avalanches on survivors' mental health beyond the first years after the accident. The aims of this study were to describe and evaluate possible differences in long-term mental health symptoms after a major avalanche disaster between exposed and unexposed soldiers using a longitudinal design.

METHOD

Present mental health symptoms were examined among avalanche exposed (n = 12) and unexposed (n = 9) soldiers by PTSS-10, IES-15 and STAI-12 in four waves (1986-1987 and 2016).

RESULTS

Binary logistic regression revealed that the odds to score above the cut-off were significantly lower for both groups after one year compared to baseline for PTSS-10 (p = 0.018) and significantly lower after 30 days compared to baseline for IES-15 (p = 0.005). Data did not reveal significant differences between the exposed and unexposed groups regarding adjusted PTSS-10, IES-15 or STAI-12 mean scores compared. Linear mixed model-analyses revealed significant effects of time. The adjusted mean scores declined over time for both groups: PTSS-10 (p = 0.001), IES-15 (p = 0.026) and STAI-12 (p = 0.001), and the time trajectories for PTSS-10 were significantly different between the groups (p = 0.013). Although not significant (all p > 0.05), results indicated that a larger proportion of soldiers in the exposed group experienced posttraumatic stress symptoms (5/12) (PTSS-10 score ≥ 4) and distress symptoms (6/12) (IES-15 score ≥ 26) above cut-off points, 30 years post-disaster.

CONCLUSIONS

The course of mental health symptoms may persist, and even increase, in selected and trained military personnel 30 years after exposure to a natural disaster. These findings may be of great importance for health authorities planning appropriate follow-up.

The Future of Climate Epidemiology: Opportunities for Advancing Health Research in the Context of Climate Change

In the coming decades, climate change is expected to dramatically affect communities worldwide, altering the patterns of many ambient exposures and disasters, including extreme temperatures, heat waves, wildfires, droughts, and floods. These exposures, in turn, can affect risks for a variety of human diseases and health outcomes. Climate epidemiology plays an important role in informing policy related to climate change and its threats to public health. Climate epidemiology leverages deep, integrated collaborations between epidemiologists and climate scientists to understand the current and potential future impacts of climate-related exposures on human health. A variety of recent and ongoing developments in climate science are creating new avenues for epidemiologic contributions. Here, we discuss the contributions of climate epidemiology and describe some key current research directions, including research to better characterize uncertainty in climate health projections. We end by outlining 3 developing areas of climate science that are creating opportunities for high-impact epidemiologic advances in the near future: 1) climate attribution studies, 2) subseasonal to seasonal forecasts, and 3) decadal predictions.

Exposure to multiple disasters: The long-term effect of Hurricane Sandy (October 29, 2012) on NYC survivors of the September 11, 2001 World Trade Center attack

This study evaluated the impact of pre-Hurricane Sandy (Sandy) post-traumatic stress disorder (PTSD) trajectories on the relationship between Sandy exposures and post-Sandy 9/11-related PTSD among World Trade Center Health Registry (Registry) enrollees. The study population included 3,199 adult Registry enrollees who completed three surveys prior to Sandy in 2003-4, 2006-7, and 2011-12; a post-Hurricane Sandy survey (2013); and a follow-up survey in 2015-16. PTSD was assessed using the PTSD Checklist (PCL). Latent class growth analysis was used to identify groups of enrollees who shared a similar trajectory of change in PCL score in the time period prior to Sandy. We compared enrollees in each trajectory group to assess the impact of Sandy-related PTSD, Sandy exposures, and optimism on 9/11-related PTSD status post-Sandy (2015-16) using bivariate analyses and multivariable log-binomial regression. Sandy-related PTSD was the strongest predictor of subsequent 9/11-related PTSD. Lower optimism and higher Sandy exposure significantly predicted 9/11-related PTSD only in some trajectory groups. Hurricane Sandy may have exacerbated previously resolved symptoms of 9/11-related PTSD. This indicates a need after a disaster to assess and address mental health sequelae from previous traumatic exposures.

Long-term effects of disaster on depressive symptoms: Type of exposure matters

RATIONALE

Natural disasters have the potential to change the lives of older people, yet most studies rely on small convenience samples, few include assessments of people prior to the disaster, and only a handful examine the effects of different types of exposure.

OBJECTIVE

Our analyses add new knowledge to the literature by examining the ways in which four types of exposure (i.e., geographic, peri-traumatic stress, personal and property loss, and post-storm hardship) affect depressive symptoms experienced by older people over a five-year period.

METHOD

We analyzed four waves of data from the ORANJ BOWL panel using multilevel mixed effects models.

RESULTS

We found that although each type of exposure had an independent effect on depressive symptoms, the effects of peri-traumatic stress were dominant.

CONCLUSIONS

As nearly 20% of people in the United States will experience a natural disaster during the course of their lives, it is critical to understand how disaster exposure can influence mental health because each type of exposure demands a different response. Finding that an individual's emotional response during the disaster plays an important role in the development of depressive symptoms suggests that reduction of exposure to traumatic stress during a storm (i.e., evacuation from a storm area) is important for older people. Likewise, immediate interventions following a disaster that target people experiencing high levels of peri-traumatic distress may be particularly effective and that failing to attend to these people may miss a critical opportunity and result in years of suffering.

A Longitudinal Study of Recurrent Experience of Earthquake and Mental Health Problems Among Chinese Adolescents

Background: The effects of recurrent exposure to disasters on adolescents’ mental health have rarely been studied. We examined the effects of two earthquake experiences 5 years apart in a longitudinal cohort of Chinese adolescents.

Methods: A total of 858 adolescents were assessed in September, 2011 (3.5 years after the Wenchuan earthquake, 1.5 years before Ya’an earthquake, T1) and April, 2013 (1 week after the Ya’an earthquake, T2). Participants’ Wenchuan earthquake experiences and symptoms of post-traumatic stress disorder (PTSD) and depression were assessed at T1, and their Ya’an earthquake experiences, Acute Stress Disorder (ASD), PTSD, and depression were assessed at T2.

Results: Structural equation models showed a positive relationship between Ya’an earthquake experiences and symptoms of ASD, PTSD, and depression at T2. T1 PTSD symptoms significantly increased T2 ASD, PTSD, and depression symptoms, and also mediated the relationships between Wenchuan earthquake experiences and T2 ASD, PTSD, and depression symptoms. T1 Depression symptoms also significantly increased T2 ASD, PTSD, and depression symptoms, but only mediated the association between Wenchuan earthquake experiences and T2 depression symptoms. In addition, Wenchuan earthquake experiences moderated the effects of Ya’an earthquake experiences on ASD symptoms and PTSD symptoms but not depression.

Conclusion: Repeated to exposure to disasters have adverse additive effects on adolescents’ mental health. Adolescents who experience one disaster may be sensitive to the negative impact of subsequent ones.

Prenatal exposure to disaster-related traumatic stress and developmental trajectories of temperament in early childhood: Superstorm Sandy pregnancy study

BACKGROUND

Little is known about the impact of prenatal maternal stress (PNMS) on the developmental trajectory of temperament and few studies have been able to incorporate a natural disaster as a quasi-experimental stressor. The current study investigated PNMS related to Superstorm Sandy ('Sandy'), a hurricane that struck the New York metropolitan area in October 2012, in terms of objective exposure during pregnancy, subjective stress reaction as assessed by maternal symptoms of post-traumatic stress, and their impact on the developmental changes in temperament during early childhood.

METHOD

A subsample of 318 mother-child dyads was drawn from the Stress in Pregnancy Study. Temperament was measured at 6, 12, 18, and 24 months of age.

RESULTS

Objective exposure was associated with greater High-Intensity Pleasure, Approach, Perceptual Sensitivity and Fearfulness, but lower Cuddliness and Duration of Orientation at 6 months. Objective exposure and its interaction with subjective stress reaction predicted developmental changes in temperament. In particular, objective exposure was linked to greater increases in Activity Level but decreases in High-Intensity Pleasure, Approach, and Fearfulness. The combination of objective exposure and subjective stress reaction was also associated with greater increases in Activity Level.

LIMITATIONS

Temperament was measured solely via maternal report. Trimester-specific effects of Sandy on temperament were not examined.

CONCLUSION

This is the first study to examine the effects of prenatal maternal exposure to a natural disaster on trajectories of early childhood temperament. Findings suggest that both objective stress exposure and subjective stress reaction in-utero predict developmental trajectories of temperament in early childhood.

Lower Respiratory Symptoms Associated With Environmental and Reconstruction Exposures After Hurricane Sandy

OBJECTIVE

In a population with prior exposure to the World Trade Center (WTC) disaster, this study sought to determine the relationship between Hurricane Sandy-related inhalation exposures and post-Sandy lower respiratory symptoms (LRS).

METHODS

Participants included 3835 WTC Health Registry enrollees who completed Wave 3 (2011-2012) and Hurricane Sandy (2013) surveys. The Sandy-related inhalational exposures examined were: (1) reconstruction exposure; (2) mold or damp environment exposure; and (3) other respiratory irritants exposure. LRS were defined as wheezing, persistent cough, or shortness of breath reported on ≥1 of the 30 days preceding survey completion. Associations between LRS and Sandy exposures, controlling for socio-demographic factors, post-traumatic stress disorder, and previously reported LRS and asthma were examined using multiple logistic regression.

RESULTS

Over one-third of participants (34.4%) reported post-Sandy LRS. Each of the individual exposures was also independently associated with post-Sandy LRS, each having approximately twice the odds of having post-Sandy LRS. We found a dose-response relationship between the number of types of Sandy-related exposures reported and post-Sandy LRS.

CONCLUSIONS

This study provides evidence that post-hurricane clean-up and reconstruction exposures can increase the risk for LRS. Public health interventions should emphasize the importance of safe remediation practices and recommend use of personal protective equipment.

Re-experiencing 9/11-Related PTSD Symptoms Following Exposure to Hurricane Sandy

Background

Understanding Pre-Existing Posttraumatic Stress Disorder (PTSD) symptoms and risk of PTSD following Hurricane Sandy (Sandy) has important implications for PTSD screening of persons exposed to multiple traumas. This study assessed the association between Sandy exposure and a subset of PTSD symptoms related to re-experiencing trauma from the events of the September 11, 2001 (9/11).

Methods

We studied 4,220 respondents from a random 8,870 person sample of adult World Trade Center Health Registry enrollees who completed a post-Sandy survey between March 28 and November 7, 2013. The symptom cluster of re-experiencing 9/11 was defined using 3 out of 5 questions in the intrusion domain of the PTSD Checklist. Multivariable logistic regression, adjusting for socio-demographics, social support and any post-9/11 life threatening events prior to Sandy, was performed separately in those symptomatic and non-symptomatic of re-experiencing 9/11 prior to Sandy.

Results

A total of 688 enrollees (16.3%) reported re-experiencing 9/11 symptoms after Sandy (58.8% in those symptomatic prior to Sandy, and 8.7% in those non-symptomatic). A significant association between Sandy exposure and re-experiencing 9/11 was observed only among those non symptomatic prior to Sandy (adjusted odds ratio (AOR)=1.7, 95% confidence interval=1.2-2.3 for moderate Sandy exposure; AOR=2.8, 2.0-4.0 for high Sandy exposure).

Conclusions

Individuals with a history of trauma should be considered for early screening and counseling for mental health after a subsequent traumatic event, regardless of PTSD status, especially in 9/11 exposed populations.

Trauma and PTSD in the WHO World Mental Health Surveys

Background: Although post-traumatic stress disorder (PTSD) onset-persistence is thought to vary significantly by trauma type, most epidemiological surveys are incapable of assessing this because they evaluate lifetime PTSD only for traumas nominated by respondents as their 'worst.' Objective: To review research on associations of trauma type with PTSD in the WHO World Mental Health (WMH) surveys, a series of epidemiological surveys that obtained representative data on trauma-specific PTSD. Method: WMH Surveys in 24 countries (n = 68,894) assessed 29 lifetime traumas and evaluated PTSD twice for each respondent: once for the 'worst' lifetime trauma and separately for a randomly-selected trauma with weighting to adjust for individual differences in trauma exposures. PTSD onset-persistence was evaluated with the WHO Composite International Diagnostic Interview. Results: In total, 70.4% of respondents experienced lifetime traumas, with exposure averaging 3.2 traumas per capita. Substantial between-trauma differences were found in PTSD onset but less in persistence. Traumas involving interpersonal violence had highest risk. Burden of PTSD, determined by multiplying trauma prevalence by trauma-specific PTSD risk and persistence, was 77.7 person-years/100 respondents. The trauma types with highest proportions of this burden were rape (13.1%), other sexual assault (15.1%), being stalked (9.8%), and unexpected death of a loved one (11.6%). The first three of these four represent relatively uncommon traumas with high PTSD risk and the last a very common trauma with low PTSD risk. The broad category of intimate partner sexual violence accounted for nearly 42.7% of all person-years with PTSD. Prior trauma history predicted both future trauma exposure and future PTSD risk. Conclusions: Trauma exposure is common throughout the world, unequally distributed, and differential across trauma types with respect to PTSD risk. Although a substantial minority of PTSD cases remits within months after onset, mean symptom duration is considerably longer than previously recognized.

Longitudinal Impact of Hurricane Sandy Exposure on Mental Health Symptoms

Hurricane Sandy hit the eastern coast of the United States in October 2012, causing billions of dollars in damage and acute physical and mental health problems. The long-term mental health consequences of the storm and their predictors have not been studied. New York City and Long Island residents completed questionnaires regarding their initial Hurricane Sandy exposure and mental health symptoms at baseline and 1 year later (N = 130). There were statistically significant decreases in anxiety scores (mean difference = -0.33, p < 0.01) and post-traumatic stress disorder (PTSD) scores (mean difference = -1.98, p = 0.001) between baseline and follow-up. Experiencing a combination of personal and property damage was positively associated with long-term PTSD symptoms (OR_adj 1.2, 95% CI [1.1-1.4]) but not with anxiety or depression. Having anxiety, depression, or PTSD at baseline was a significant predictor of persistent anxiety (OR_adj 2.8 95% CI [1.1-6.8], depression (OR_adj 7.4 95% CI [2.3-24.1) and PTSD (OR_adj 4.1 95% CI [1.1-14.6]) at follow-up. Exposure to Hurricane Sandy has an impact on PTSD symptoms that persists over time. Given the likelihood of more frequent and intense hurricanes due to climate change, future hurricane recovery efforts must consider the long-term effects of hurricane exposure on mental health, especially on PTSD, when providing appropriate assistance and treatment.

Exposure to Hurricane Sandy, neighborhood collective efficacy, and post-traumatic stress symptoms in older adults

OBJECTIVES

Older adults exposed to natural disasters are at risk for negative psychological outcomes such as post-traumatic stress disorder (PTSD). Neighborhood social capital can act as a resource that supports individual-level coping with stressors. This study explores the ability of perceived neighborhood collective efficacy, a form of social capital, to moderate the association between exposure to Hurricane Sandy and PTSD symptoms in older adults.

METHOD

Data from 2205 older individuals aged 54-80 residing in New Jersey who self-reported exposure to Hurricane Sandy in October of 2012 were identified and extracted from the ORANJ BOWL™ research panel. Participants completed baseline assessments of demographic and individual-level characteristics in 2006-2008 and follow-up assessments about storm exposure, perceived neighborhood collective efficacy (social cohesion and social control), and PTSD symptoms 8-33 months following the storm. Zero-inflated Poisson regression models were tested to examine the association between exposure, neighborhood collective efficacy, and PTSD symptoms.

RESULTS

After accounting for known demographic and individual-level covariates, greater storm exposure was linked to higher levels of PTSD symptoms. Social cohesion, but not social control, was linked to lower reports of PTSD symptoms and moderated the association between exposure and PTSD. The impact of storm exposure on PTSD symptoms was less for individuals reporting higher levels of social cohesion.

CONCLUSION

Mental health service providers and disaster preparedness and response teams should consider the larger social network of individuals served. Building social connections in older adults' neighborhoods that promote cohesion can reduce the negative psychological impact of a disaster.

Hurricane Sandy Exposure and the Mental Health of World Trade Center Responders

The psychological consequences of a second disaster on populations exposed to an earlier disaster have rarely been studied prospectively. Using a pre- and postdesign, we examined the effects of Hurricane Sandy on possible World Trade Center (WTC) related posttraumatic stress disorder (PTSD Checklist score of ≥ 50) and overall depression (major depressive disorder [MDD]; Patient Health Questionnaire depression score of ≥ 10) among 870 WTC responders with a follow-up monitoring visit at the Long Island WTC Health Program during the 6 months post-Hurricane Sandy. The Hurricane Sandy exposures evaluated were damage to home (8.3%) and to possessions (7.8%), gasoline shortage (24.1%), prolonged power outage (42.7%), and filing a Federal Emergency Management Agency claim (11.3%). A composite exposure score also was constructed. In unadjusted analyses, Hurricane Sandy exposures were associated with 1.77 to 5.38 increased likelihood of PTSD and 1.58 to 4.13 likelihood of MDD; odds ratios for ≥ 3 exposures were 6.47 for PTSD and 6.45 for MDD. After adjusting for demographic characteristics, WTC exposure, pre-Hurricane Sandy mental health status, and time between assessments, reporting ≥ 3 Hurricane Sandy exposures was associated with a 3.29 and 3.71 increased likelihood of PTSD and MDD, respectively. These findings underscore the importance of assessing the impact of a subsequent disaster in ongoing responder health surveillance programs.

Association of DSM-IV Posttraumatic Stress Disorder With Traumatic Experience Type and History in the World Health Organization World Mental Health Surveys

IMPORTANCE

Previous research has documented significant variation in the prevalence of posttraumatic stress disorder (PTSD) depending on the type of traumatic experience (TE) and history of TE exposure, but the relatively small sample sizes in these studies resulted in a number of unresolved basic questions.

OBJECTIVE

To examine disaggregated associations of type of TE history with PTSD in a large cross-national community epidemiologic data set.

DESIGN, SETTING, AND PARTICIPANTS

The World Health Organization World Mental Health surveys assessed 29 TE types (lifetime exposure, age at first exposure) with DSM-IV PTSD that was associated with 1 randomly selected TE exposure (the random TE) for each respondent. Surveys were administered in 20 countries (n = 34 676 respondents) from 2001 to 2012. Data were analyzed from October 1, 2015, to September 1, 2016.

MAIN OUTCOMES AND MEASURES

Prevalence of PTSD assessed with the Composite International Diagnostic Interview.

RESULTS

Among the 34 676 respondents (55.4% [SE, 0.6%] men and 44.6% [SE, 0.6%] women; mean [SE] age, 43.7 [0.2] years), lifetime TE exposure was reported by a weighted 70.3% of respondents (mean [SE] number of exposures, 4.5 [0.04] among respondents with any TE). Weighted (by TE frequency) prevalence of PTSD associated with random TEs was 4.0%. Odds ratios (ORs) of PTSD were elevated for TEs involving sexual violence (2.7; 95% CI, 2.0-3.8) and witnessing atrocities (4.2; 95% CI, 1.0-17.8). Prior exposure to some, but not all, same-type TEs was associated with increased vulnerability (eg, physical assault; OR, 3.2; 95% CI, 1.3-7.9) or resilience (eg, participation in sectarian violence; OR, 0.3; 95% CI, 0.1-0.9) to PTSD after the random TE. The finding of earlier studies that more general history of TE exposure was associated with increased vulnerability to PTSD across the full range of random TE types was replicated, but this generalized vulnerability was limited to prior TEs involving violence, including participation in organized violence (OR, 1.3; 95% CI, 1.0-1.6), experience of physical violence (OR, 1.4; 95% CI, 1.2-1.7), rape (OR, 2.5; 95% CI, 1.7-3.8), and other sexual assault (OR, 1.6; 95% CI, 1.1-2.3).

CONCLUSION AND RELEVANCE

The World Mental Health survey findings advance understanding of the extent to which PTSD risk varies with the type of TE and history of TE exposure. Previous findings about the elevated PTSD risk associated with TEs involving assaultive violence was refined by showing agreement only for repeated occurrences. Some types of prior TE exposures are associated with increased resilience rather than increased vulnerability, connecting the literature on TE history with the literature on resilience after adversity. These results are valuable in providing an empirical rationale for more focused investigations of these specifications in future studies.

The trauma signature of 2016 Hurricane Matthew and the psychosocial impact on Haiti

Background. Hurricane Matthew was the most powerful tropical cyclone of the 2016 Atlantic Basin season, bringing severe impacts to multiple nations including direct landfalls in Cuba, Haiti, Bahamas, and the United States. However, Haiti experienced the greatest loss of life and population disruption. Methods. An established trauma signature (TSIG) methodology was used to examine the psychological consequences of Hurricane Matthew in relation to the distinguishing features of this event. TSIG analyses described the exposures of Haitian citizens to the unique constellation of hazards associated with this tropical cyclone. A hazard profile, a matrix of psychological stressors, and a "trauma signature" summary for the affected population of Haiti - in terms of exposures to hazard, loss, and change - were created specifically for this natural ecological disaster. Results. Hazard characteristics of this event included: deluging rains that triggered mudslides along steep, deforested terrain; battering hurricane winds (Category 4 winds in the "eye-wall" at landfall) that dismantled the built environment and launched projectile debris; flooding "storm surge" that moved ashore and submerged villages on the Tiburon peninsula; and pummeling wave action that destroyed infrastructure along the coastline. Many coastal residents were left defenseless to face the ravages of the storm. Hurricane Matthew's slow forward progress as it remained over super-heated ocean waters added to the duration and degree of the devastation. Added to the havoc of the storm itself, the risks for infectious disease spread, particularly in relation to ongoing epidemics of cholera and Zika, were exacerbated. Conclusions. Hurricane Matthew was a ferocious tropical cyclone whose meteorological characteristics amplified the system's destructive force during the storm's encounter with Haiti, leading to significant mortality, injury, and psychological trauma.

Quality of Life of Persons Injured on 9/11: Qualitative Analysis from the World Trade Center Health Registry

Introduction: A number of studies published by the World Trade Center Health Registry (Registry) document the prevalence of injuries sustained by victims of the World Trade Center Disaster (WTCD) on 9/11. Injury occurrence during or in the immediate aftermath of this event has been shown to be a risk factor for long-term adverse physical and mental health status. More recent reports of ongoing physical health and mental health problems and overall poor quality of life among survivors led us to undertake this qualitative study to explore the long-term impact of having both disaster-related injuries and peri-event traumatic exposure on quality of life in disaster survivors. 

Methods: Semi-structured, in-depth individual telephone interviews were conducted with 33 Registry enrollees who reported being injured on 9/11/01. Topics included: extent and circumstance of the injury(ies), description of medical treatment for injury, current health and functional status, and lifestyle changes resulting from the WTCD. The interviews were recorded, transcribed, and inductively open-coded for thematic analysis.

Results: Six themes emerged with respect to long term recovery and quality of life: concurrent experience of injury with exposure to peri-event traumatic exposure (e.g., witnessing death or destruction, perceived life threat, etc.); sub-optimal quality and timeliness of short- and long-term medical care for the injury reported and mental health care; poor ongoing health status, functional limitations, and disabilities; adverse impact on lifestyle; lack of social support; and adverse economic impact. Many study participants, especially those reporting more serious injuries, also reported self-imposed social isolation, an inability to participate in or take enjoyment from previously enjoyable leisure and social activities and greatly diminished overall quality of life.

Discussion: This study provided unique insight into the long-term impact of disasters on survivors. Long after physical injuries have healed, some injured disaster survivors report having serious health and mental health problems, economic problems due to loss of livelihood, limited sources of social support, and profound social isolation. Strategies for addressing the long-term health problems of disaster survivors are needed in order to support recovery.

Increased Incidence Rate of Trauma- and Stressor-Related Disorders in Denmark After the September 11, 2001, Terrorist Attacks in the United States

The terrorist attacks that occurred on September 11, 2001 (hereafter referred to as 9/11) in the United States had a profound impact on the physical and mental health of Americans, but the effects beyond the United States are largely unknown. To understand the wider aftermath, we examined the consequences of the 9/11 attacks on mental disorders in the Kingdom of Denmark. Utilizing population data from the Danish Psychiatric Central Research Register from 1995 to 2012, we used a time-series intervention approach to estimate the change in the incidence rate of mental disorders after the 9/11 attacks. Based on analyses of 1,448,250 contacts with psychiatric services, we found that the attacks were followed by an immediate 16% increase in the incidence rate of trauma- and stressor-related disorders. This surge dissipated approximately a year after 9/11. In contrast, no similar increases were found for other disorders. This is consistent with the prominent role of external stressors in the etiology of trauma- and stressor-related disorders. The results indicate that the effects of 9/11 on mental disorders extended across the Atlantic Ocean to Denmark. Thus, the impact of terrorist attacks on mental health is likely not limited to inhabitants of the country under attack; it also extends to people far away and without immediate relation to it.

Mental health status of World Trade Center tower survivors compared to other survivors a decade after the September 11, 2001 terrorist attacks

BACKGROUND

Studies of individuals directly exposed to the World Trade Center (WTC) terrorist attacks of September 11, 2001 have found increased risk for post-traumatic stress disorder (PTSD) and binge drinking (BD). No long-term studies have been conducted on one highly exposed group, WTC tower evacuees.

METHODS

The study sample included 7,695 adult civilians in the WTC Health Registry. Logistic regression was used to examine the odds of PTSD and BD in 1,946 towers evacuees compared to 5,749 others in nearby buildings or on the street.

RESULTS

WTC tower survivors were at increased risk for PTSD and BD compared to the others. Infrastructure and behavioral barriers experienced during evacuation were significantly associated with PTSD.

CONCLUSIONS

WTC tower evacuees are at increased risk for PTSD and BD. Understanding the effects of disaster-related evacuation barriers on the long-term mental health status of survivors can help in the planning of continuing post-disaster treatment. Am. J. Ind.

Impact of 9/11-related chronic conditions and PTSD comorbidity on early retirement and job loss among World Trade Center disaster rescue and recovery workers

BACKGROUND

The economic impact of the 9/11 terrorist attacks has rarely been studied. We examined the association between 9/11-related chronic health conditions with or without post-traumatic stress disorder (PTSD) and one important aspect of the economic impact, retirement, and job loss before age 60.

METHODS

A total of 7,662 workers who participated in the World Trade Center Health Registry surveys were studied. Logistic regression models examined the association of 9/11-related health and labor force exit.

RESULTS

Workers with chronic conditions were more likely to experience early retirement and job loss, and the association was stronger in the presence of PTSD comorbidity: the odds ratios for reporting early retirement or job loss were increased considerably when chronic conditions were comorbid with PTSD.

CONCLUSIONS

Disaster-related health burden directly impacts premature labor force exit and income. Future evaluation of disaster outcome should include its long-term impact on labor force. Am. J. Ind. Med. 59:731-741, 2016. © 2016 Wiley Periodicals, Inc.

Hurricane Sandy Evacuation Among World Trade Center Health Registry Enrollees in New York City

Objective

Timely evacuation is vital for reducing adverse outcomes during disasters. This study examined factors associated with evacuation and evacuation timing during Hurricane Sandy among World Trade Center Health Registry (Registry) enrollees.

Methods

The study sample included 1162 adults who resided in New York City’s evacuation zone A during Hurricane Sandy who completed the Registry’s Hurricane Sandy substudy in 2013. Factors assessed included zone awareness, prior evacuation experience, community cohesion, emergency preparedness, and poor physical health. Prevalence estimates and multiple logistic regression models of evacuation at any time and evacuation before Hurricane Sandy were created.

Results

Among respondents who evacuated for Hurricane Sandy (51%), 24% had evacuated before the storm. In adjusted analyses, those more likely to evacuate knew they resided in an evacuation zone, had evacuated during Hurricane Irene, or reported pre-Sandy community cohesion. Evacuation was less likely among those who reported being prepared for an emergency. For evacuation timing, evacuation before Hurricane Sandy was less likely among those with pets and those who reported 14 or more poor physical health days.

Conclusions

Higher evacuation rates were observed for respondents seemingly more informed and who lived in neighborhoods with greater social capital. Improved disaster messaging that amplifies these factors may increase adherence with evacuation warnings. (Disaster Med Public Health Preparedness. 2016;10:411–419)

Vulnerable, But Why? Post-Traumatic Stress Symptoms in Older Adults Exposed to Hurricane Sandy

OBJECTIVE

Drawing on pre-disaster, peri-disaster, and post-disaster data, this study examined factors associated with the development of post-traumatic stress disorder (PTSD) symptoms in older adults exposed to Hurricane Sandy.

METHODS

We used a sample of older participants matched by gender, exposure, and geographic region (N=88, mean age=59.83 years) in which one group reported clinically significant levels of PTSD symptoms and the other did not. We conducted t-tests, chi-square tests, and exact logistic regressions to examine differences in pre-disaster characteristics and peri-disaster experiences.

RESULTS

Older adults who experienced PTSD symptoms reported lower levels of income, positive affect, subjective health, and social support and were less likely to be working 4 to 6 years before Hurricane Sandy than were people not experiencing PTSD symptoms. Those developing PTSD symptoms reported more depressive symptoms, negative affect, functional disability, chronic health conditions, and pain before Sandy and greater distress and feelings of danger during Hurricane Sandy. Exact logistic regression revealed independent effects of preexisting chronic health conditions and feelings of distress during Hurricane Sandy in predicting PTSD group status.

CONCLUSIONS

Our findings indicated that because vulnerable adults can be identified before disaster strikes, the opportunity to mitigate disaster-related PTSD exists through identification and resource programs that target population subgroups. (Disaster Med Public Health Preparedness. 2016;10:362-370).

Rising to the Challenge: The Response to Hurricane Sandy in a Psychiatric Emergency Room

BACKGROUND

In October 2012, Hurricane Sandy ravaged the East coast claiming 159 lives and destroying an estimated $65 billion in property. Overnight, hospitals still in operation, such as Maimonides Medical Center, were faced with seemingly insurmountable challenges in providing adequate health care services.

OBJECTIVES

This study had 3 goals: (1) to assess the impact of Hurricane Sandy on the number and pattern of visits to the psychiatric emergency room (PER) at Maimonides Medical Center; (2) to analyze the procedures implemented in addressing increased demands; and (3) to identify any shortcomings in our response and explore how it can be altered to face future challenges.

METHODS

We reviewed systems data for the 12 months before and after Hurricane Sandy, including total number of visits to the PER, length of stay in the PER, and percentage of admissions and discharges from the PER. We also reviewed the interventions implemented by the designated response unit, the Command Center, and interviewed senior leadership involved in the process.

RESULTS

The total number of visits increased dramatically, with the highest increase recorded in the first month after Hurricane Sandy. There were 3554 visits in the 12 months before the hurricane compared with 4674 in the 12 months after the storm (P<0.001). In addition, there were 273 visits to the PER in November 2011 compared with 408 in November 2012, which was the month after the hurricane (P<0.001). The average length of stay increased and the percentage of admissions decreased significantly (P<0.001). There were no increased staff assignments, but significant resources were provided by the Command Center.

CONCLUSIONS

The results of this study highlight the fact that hospitals can never be over-prepared for disasters. By being adaptive and creative, the PER was able to serve a greater number of patients, which is critical in the current health care environment.
