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

Prevalence of increased alcohol use and alcohol use disorders in adult victims of terrorist attacks: a systematic and meta-analytic review

Background: Previous studies have reviewed the evidence on the increase in alcohol consumption after a terrorist attack. However, an increase does not necessarily imply the presence of an alcohol use disorder.Objectives: To conduct a systematic and meta-analytic review of the literature on the prevalence of increased alcohol consumption and alcohol use disorders in adult exposed to terrorism.Methods: A search of PsycINFO, MEDLINE and PTSDpubs identified 29 studies published up to March 2023 in which 38 adult samples totaling 282,753 persons exposed to terrorism were assessed. Using inverse variance heterogeneity models, pooled prevalence rates of increased alcohol use and alcohol use disorders were calculated.Results: 6% (95% CI [2.9, 9.5]) of the adults exposed to a terrorist attack increased their alcohol consumption. The prevalence of increased alcohol use varied depending on the degree of exposure (p = .006, R2 = .18) and the procedure for measuring increases (p = .043, R2 = .37). The prevalence of alcohol use disorders in adults exposed to a terrorist attack was 5.5% (95% CI [3.7, 7.5]), a rate that was not higher than that obtained in the general population and varied depending on the type of alcohol disorder (p = .015, R2 = .30).Conclusions: A relevant number of adults exposed to terrorist attacks will subsequently increase their alcohol consumption, but this increase is not associated with an increase in the prevalence of alcohol use disorders. Effects of terrorism on people's health are potentially widespread, but concerns of excessive alcohol use after terrorist attacks may be unwarranted.

Terrorism’s Impact on Mental Health Outcomes among Directly and Indirectly Exposed Victims and the Development of Psychopathology

After the events of 9/11, many police-responders developed post-traumatic stress disorder (PTSD) and were potentially vulnerable to developing depression and/or anxiety; in addition, nearly half of police with probable PTSD had comorbid depression and anxiety. Having in mind that victims who experience the effects of terrorism are exposed to high levels of psychological damage, we thus aimed to determine how sequelae of a terrorist act directly and indirectly affect victims. Quantitative synthesis findings were concluded on the basis of 200 records that met the inclusion criteria out of a total of 650. We grouped the patients according to their level of exposure to the WTC terrorist attack on 11 September 2001. The Level I group included individuals who had experienced the traumatic event and/or those who had observed the attack. The Level II group consisted of rescuers and/or persons who cleaned up debris in the area after the attack. The Level III group comprised the victims’ families. Our research enabled us to create a profile for those who were most vulnerable to mental disorders after the WTC terrorist attack. Patients who had survived the terrorist attack and/or those who had observed the incident exhibited fewer traumatic symptoms and a lower percentage of suicidal thoughts in comparison to individuals who had worked as rescuers or cleaning staff in the area after the attack. The number of symptoms rose along with increased contact time with the stressor. The dominant symptom was the triad of intrusion, avoidance, and hyperarousal. The findings may confirm the positive effect of protracted court cases in legal proceedings for compensation on the maintenance and development of psychopathology. Our research may contribute to a better understanding of the consequences of terrorism outcomes on the human psyche and be used in the development of standards for dealing with victims of terrorism’s impact.

Anxiety, Depression and Posttraumatic Stress Disorder after Terrorist Attacks: A General Review of the Literature

Terrorism, though not well-defined, is a violent act that has been shown to have longstanding effects on the mental health of those who witness it. The aim of this general literature review is to explore the effect that terrorism has on posttraumatic stress disorder (PTSD), major depressive disorder (MDD) and anxiety disorders, as well as the bio-psycho-social determinants that mediate its impact. This paper describes the prevalence, risk factors, protective factors, common presentations and interventions identified for PTSD, depression and anxiety disorders occurring following terrorist attacks. We conducted a literature search in MEDLINE using a number of keywords detailed below. After applying inclusion and exclusion criteria, we kept 80 articles, which we summarized in tabular form. A majority of articles found detailed the impact of terrorism on PTSD, and took place in a Western, mainly American setting. The main factors that impacted the presentation of mental illness include gender, ethnicity, social supports, socioeconomic status, level of preparedness, level of exposure, pre-existing trauma and mental illness, and subsequent life stressors. The main intervention detailed in this article as showing evidence post-terrorism is trauma-focused cognitive-behavioural therapy. This study highlights the importance of this topic, and in particular, its implications for public health policy and practice.

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.

Post-Traumatic Stress Disorder among Survivors of the September 11, 2001 World Trade Center Attacks: A Review of the Literature

Prior reviews of 9/11-related post-traumatic stress disorder (PTSD) have not focused on the civilian survivors most directly exposed to the attacks. Survivors include those individuals who were occupants of buildings in or near the World Trade Center (WTC) towers, those whose primary residence or workplace was in the vicinity, and persons who were on the street passing through the area. This review reports published information on the prevalence of and risk factors for PTSD, as well as comorbidities associated with PTSD among 9/11 survivors. Articles selected for inclusion met the following criteria: (1) full-length, original peer-reviewed empirical articles; (2) published in English from 2002-2019; (3) collected data from persons directly exposed; (4) adult populations; and (5) focused on non-rescue or recovery workers (i.e., survivors). Data were extracted with focus on study design, sample size, time frame of data collection post-9/11, PTSD assessment instrument, and PTSD prevalence, risk factors, and comorbidities. Our review identified the use of cross-sectional and longitudinal designs, finding multiple direct comorbidities with PTSD, as well as the prevalence and persistence of PTSD. Future research would benefit from incorporating more mixed methods designs, and exploring the mediating mechanisms and protective factors of the known associations of PTSD among the 9/11 survivor population.

Assessment of cumulative health risk in the World Trade Center general responder cohort

BACKGROUND

Multiple comorbidities have been reported among rescue/recovery workers responding to the 9/11/2001 WTC disaster. In this study, we developed an index that quantifies the cumulative physiological burden of comorbidities and predicts life expectancy in this cohort.

METHODS

A machine learning approach (gradient boosting) was used to model the relationship between mortality and several clinical parameters (laboratory test results, blood pressure, pulmonary function measures). This model was used to construct a risk index, which was validated by assessing its association with a number of health outcomes within the WTC general responder cohort.

RESULTS

The risk index showed significant associations with mortality, self-assessed physical health, and onset of multiple chronic conditions, particularly COPD, hypertension, asthma, and sleep apnea.

CONCLUSION

As an aggregate of several clinical parameters, this index serves as a cumulative measure of physiological dysregulation and could be utilized as a prognostic indicator of life expectancy and morbidity risk.

Posttraumatic Stress Disorder, Gender, and Risk Factors: World Trade Center Tower Survivors 10 to 11 Years After the September 11, 2001 Attacks

Ten to eleven years after the September 11, 2001 terrorist attacks, probable posttraumatic stress disorder (PTSD) was evaluated in 1,755 World Trade Center (WTC) evacuees based on data from the WTC Health Registry. Characteristics of men and women were compared and factors associated with PTSD symptom severity were examined using the PTSD Checklist (PCL). Compared with men (n = 1,015, 57.8%), women (n = 740, 42.2%) were younger and of lower socioeconomic status. Ten to eleven years after September 11, 2001, 13.7% of men and 24.1% of women met criteria for PTSD. Results indicated that when considered with all other variables (i.e., demographic, socioeconomic and social resources, exposure to the attacks, life events), gender was not a significant predictor of PTSD symptom severity. Being younger on September 11, 2001, unemployed, less educated, and/or having higher exposure to the attacks, unmet mental health care needs, and less social support predicted higher PCL scores for both genders (βs = .077 to .239). Demographic characteristics and socioeconomic resources (ΔR² = .113) accounted for the largest amount of variance in PCL scores over and above exposure/evacuation, mental healthcare needs, and social support variables (ΔR² = .093 to .102). When trends of unmet mental healthcare needs were analyzed, the most prevalent response for men was that they preferred to manage their own symptoms (15.1%), whereas the most prevalent response for women was that they could not afford to pay for mental health care (14.7%). Although the prevalence of probable PTSD in women tower survivors was approximately twice as high as it was for men, this is attributable largely to demographic and socioeconomic resource factors and not gender alone. Implications for treatment and interventions are discussed.
