Self‐inflicted injury is a known risk factor for suicide. Previous studies have reported associations between posttraumatic stress disorder (PTSD) and self‐inflicted injury; however, this association has not been widely studied among disaster‐exposed populations. Among 50,386 enrollees in the World Trade Center Health Registry, a cohort of individuals exposed to the September 11, 2001, attacks in New York City (9/11), we examined longitudinal associations between probable 9/11‐related PTSD and hospitalizations and emergency department (ED) visits for self‐inflicted injuries that occurred between study enrollment (2003–2004) and 2015. Time‐dependent Cox proportional hazard models were used to estimate hazard ratios and 95% confidence intervals (CIs) for associations of time‐varying probable 9/11‐related PTSD and self‐inflicted injury, adjusting for sociodemographic and pre‐9/11 mental health symptoms. At study enrollment, 11.0% of enrollees had probable PTSD. Over a median follow‐up period of 11.2 years, a total of 171 hospitalizations/ED visits for self‐inflicted injury occurred among 146 enrollees. When comparing individuals with probable PTSD to those without probable PTSD, the multivariable‐adjusted hazard ratio for self‐inflicted injury was 2.45, 95% CI [1.63, 3.66]. Evidence of effect modification by age group was not observed. Our findings suggest that surveillance for PTSD among disaster‐exposed populations may help identify individuals at high risk of self‐inflicted injury who could benefit from targeted interventions.

Aims: The aim of this study was to characterize the circumstances of drug overdose deaths and determine whether naloxone administration differed by overdose decedent race and ethnicity.Design and setting: Analysis of data on unintentional and undetermined intent drug overdose deaths in Pennsylvania (2019–21) was collected from death certificates and the State Unintentional Drug Overdose Reporting System. Multivariable logistic regression models were adjusted for overdose death circumstances and the odds of naloxone administration were estimated by race/ethnicity and year.Cases: The analytical sample included 3386 fatal overdose decedents in 2019, 3864 in 2020 and 3816 in 2021.Measurements: Evidence of naloxone administration (yes/no) was defined using scene evidence and toxicology reports from coroner and medical examiner records, while race/ethnicity (Hispanic, non‐Hispanic Black, non‐Hispanic White) was based on the death certificate.Findings: In the analytic sample, overdose death rates were the highest among Black people and increased over time (rate per 10 000 population, 2019: 4.3; 2020: 6.1; 2021: 6.5); rates were lowest among White people and remained constant over time (rate per 10 000 population, 2019: 2.6; 2020: 2.7; 2021: 2.6). Throughout all years, Black decedents had approximately 40–50% lower odds of naloxone administration compared with White decedents as referent [2019: odds ratio (OR) = 0.7, 95% confidence interval (CI) = 0.5–0.9; 2020: OR = 0.5, 95% CI = 0.4–0.7; 2021: OR = 0.6, 95% CI = 0.5–0.8], while Hispanic decedents had similar odds of naloxone administration to that of White decedents.Conclusion: After controlling for overdose circumstances in drug overdose deaths in Pennsylvania, USA, from 2019 to 2021, Black people had lower odds of naloxone administration compared with White people, while there were no differences between Hispanic and White people.

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.

Background: Previous research has found higher than expected suicide mortality among rescue/recovery workers (RRWs) enrolled in the World Trade Center Health Registry (WTCHR). Whether any enrollee suicides are related to the decedents’ experiences on 9/11 is unknown. We abstracted medical examiner file data to learn more about 9/11-related circumstances of suicides among WTCHR enrollees. Methods: We identified 35 enrollee suicide cases that occurred in New York City using linked vital records data. We reviewed medical examiner files on each case, abstracting demographic and circumstantial data. We also reviewed survey data collected from each case at WTCHR enrollment (2003–2004) and available subsequent surveys to calculate descriptive statistics. Results: Cases were mostly non-Hispanic White (66%), male (83%), and middle-aged (median 58 years). Nineteen decedents (54%) were RRWs, and 32% of them worked at the WTC site for >90 days compared to 18% of the RRW group overall. In the medical examiner files of two cases, accounts from family mentioned 9/11-related circumstances, unprompted. All deaths occurred during 2004–2018, ranging from one to four cases per year. Leading mechanisms were hanging/suffocation (26%), firearm (23%), and jump from height (23%). Sixty percent of the cases had depression mentioned in the files, but none mentioned posttraumatic stress disorder. Conclusions: RRWs may be at particular risk for suicide, as those who worked at the WTC site for long periods appeared to be more likely to die by suicide than other RRWs. Mental health screening and treatment must continue to be prioritized for the 9/11-exposed population. More in-depth investigations of suicides can elucidate the ongoing impacts of 9/11.

Background: Among Veterans, post-traumatic stress disorder (PTSD) has been shown to be associated with obesity and accelerated weight gain. Less is known among the general population. We sought to determine the impact of PTSD on body mass index (BMI) and weight change among individuals with exposure to the World Trade Center (WTC) disaster.Methods: We examined individuals from the WTC Health Registry. PTSD symptoms were assessed on multiple surveys (Waves 1–4) using the PTSD Checklist-Specific. Three categories of post-9/11 PTSD were derived: no, intermittent, and persistent. We examined two outcomes: (1) Wave 3 BMI (normal, overweight, and obese) and (2) weight change between Waves 3 and 4. We used multivariable logistic regression to assess the association between PTSD and BMI (N = 34 958) and generalized estimating equations to assess the impact of PTSD on weight change (N = 26 532). Sex- and age-stratified analyses were adjusted for a priori confounders.Results: At Wave 3, the observed prevalence of obesity was highest among the persistent (39.5%) and intermittent PTSD (36.6%) groups, compared to the no PTSD group (29.3%). In adjusted models, persistent and intermittent PTSD were consistently associated with a higher odds of obesity. Weight gain was similar across all groups, but those with persistent and intermittent PTSD had higher estimated group-specific mean weights across time.Conclusions: Our findings that those with a history of PTSD post-9/11 were more likely to have obesity is consistent with existing literature. These findings reaffirm the need for an interdisciplinary focus on physical and mental health to improve health outcomes.

The association between health outcomes and income, education, race/ethnicity, and other proxies of socioeconomic status (SES) has been well described, but the causal drivers of this association remain poorly understood. The precise pathways that lead those of lower SES to have poorer health outcomes compared with those of higher SES remain surprisingly understudied owing to lack of large-scale studies with information appropriate for mediational analysis.
