RESUMEN

INTRODUCTION: Each year, thousands of individuals enlist in the Department of the Air Force (DAF), with some seeking to become DAF Special Warfare (SW) candidates. This study aimed to compare the anthropomorphic and physical fitness characteristics between these groups during fiscal years (FYs) 2019-2023. METHODS:  The sample includes male candidates below the age of 30 who attended the DAF basic military training (BMT) from FY2019 to 2023 (N = 119,415). Initial physical fitness testing was conducted during week 1 of BMT. Physical fitness results, height, weight, and body mass index (BMI) were compared between the two cohorts. A two-way analysis of variance was performed to analyze the effects of group (SW and non-SW) and FY on mean anthropomorphic and physical fitness test variables. Dependent variables were evaluated for homogeneity of variance using Levene's test and for normality using the Shapiro-Wilk test. The Tukey-Kramer test was employed for post hoc analyses with a threshold for statistical significance of α < 0.05. RESULTS:  The cohort of SW recruits displayed superior physical fitness results across all FYs (p < 0.001) with the exception of FY2021. They were significantly taller and heavier, and had a higher BMI when compared to non-SW DAF BMT recruits (p < 0.001). Mean values for maximum push-ups and sit-ups for SW recruits were significantly lower in FY2021 (p < 0.001) and not significantly different from non-SW recruits. Additionally, run times for both SW- and non-SW-bound recruits during FY2022 and FY2023 were significantly slower than previous years. CONCLUSIONS:  These findings can be used to establish a baseline for anthropometric and physical fitness profiles of incoming SW and non-SW DAF BMT recruits that may inform clinicians, human performance professionals, and military training leaders with information necessary to guide future research and physical fitness policy.

RESUMEN

Developing strong resiliency and care solutions for airmen and guardians is key to human capital development and force readiness. The True North program is one of the Department of the Air Force's (DAF's) most significant recent investments in promoting the resiliency of its people. Assessing the program's level of success, justifying funding, and informing decisions about the program's future will require a rigorous evaluation. The authors of this study (1) identify desired outcomes for members participating in the program, (2) define appropriate measures of effectiveness that could be used in evaluating the True North program, and (3) make recommendations for ongoing internal evaluation of the program. The True North program encompasses selected installation welcome centers, embedded religious support teams (RSTs), and embedded mental health (EMH) teams. To determine how DAF might evaluate this program and its components, the authors reviewed relevant policies and procedures and literature relevant to the program components and conducted interviews with 17 True North program personnel and 21 group and squadron commanders. They present a program logic model to determine potential evaluation measures.

RESUMEN

Most U.S. Air Force medical personnel spend their time at military treatment facilities (MTFs) caring for patients whose ailments are far less complex or urgent than the severe trauma-related injuries they would see in war. This mismatch between peacetime and wartime medical care necessitates a deliberate effort on the part of the Air Force Medical Service (AFMS) as a whole and the Pacific Air Forces (PACAF) to ensure that personnel in critical medical specialties receive the training and hands-on clinical experience they need to save lives in a high-casualty environment. The goal of this research project was to investigate approaches for increasing readiness and proficiency. To develop a portfolio of readiness building activities, the authors analyzed manpower and personnel data, reviewed Comprehensive Medical Readiness Program (CMRP) checklists and relevant literature, engaged in discussions with the stakeholder community, and developed models of the assignment system and of skill acquisition and decay. They present their findings and recommendations for the future and have developed a prototype framework to demonstrate a possible method for deciding which readiness building activities and assignment policies to employ.

RESUMEN

Background: The Thai Qualifications Framework for Higher Education (TQF: HEd) serves as a framework to enhance the quality of higher education in Thailand. However, no valid and reliable TQF: HEd instrument is available to measure the quality of graduates among Royal Thai Air Force Nurses. Objective: This study aimed to assess the psychometric properties of the TQF: HEd instrument among graduate nurses of the Royal Thai Air Force. Methods: Psychometric testing of the instrument was conducted. The instrument's validity was evaluated through a review by a panel of five experts, providing a content validity index (CVI). Construct validity was assessed using Confirmatory Factor Analysis (CFA) with a sample size of 308, and Cronbach's α coefficient was utilized to measure the scale's internal consistency. Results: The Scale-Content Validity Index (S-CVI) was 0.88. CFA yielded the following fit indices: χ2 = 265.861, p = 0.068, df = 233, χ2/df ratio = 1.141, Comparative fit index (CFI) = 0.996, Tucker Lewis Index (TLI) = 0.993, Root Mean Square Error of Approximation (RMSEA) = 0.021, and Standardized Root Mean Square Residual (SRMR) = 0.033. The scale reliability was acceptable, with a Cronbach's alpha coefficient of 0.93 and 0.85-0.92 for the six factors. Conclusion: The TQF: HEd instrument demonstrates satisfactory psychometric properties, which will be valuable for those in charge of the curriculum in utilizing the instrument to measure graduate competency and guide curriculum development.

RESUMEN

The U.S. Air Force asked RAND Project AIR FORCE (PAF) to help assess the well-being of its wounded members and the quality of services provided to facilitate their recovery and reintegration. RAND PAF fielded a survey in the fall of 2016 to assess wounded airmen's functioning in the domains of physical health, mental health, interpersonal relationships, unemployment, and financial status, as well as their utilization and perceptions of Air Force nonmedical programs for wounded airmen. The authors of this study invited all 713 wounded airmen enrolled in the Air Force Wounded Warrior program to complete the survey, and 270 airmen (38 percent) completed it. One-third of airmen reported difficulty obtaining care for physical or mental health conditions, and one-quarter expressed dissatisfaction with coordination of care. Similar proportions of airmen reported barriers to care for physical and mental health conditions. Difficulty scheduling appointments was the most commonly endorsed barrier for both types of conditions. Small but notable proportions of airmen reported potential social support deficits, unemployment, and financial problems. For many of the Air Force's programs for wounded airmen, over 80 percent of program users reported overall program satisfaction. The authors recommend that the Air Force consider focusing on improving care coordination, increasing health care system capacity, continuing employment assistance, and improving marketing of programs with low uptake.

RESUMEN

Inadequate sleep is an on-going risk to the health and mission readiness of U.S. Armed Forces, with estimates of sleep problems high above U.S. civilian populations. Intervening early in the career of active duty Air Force personnel (or "Airmen") with education and the establishment of healthy behaviors may prevent short and long term-detriments of sleep problems. This paper describes the results of a qualitative study seeking to understand the facilitators and barriers to achieving good sleep in a technical training school during the first year of entry into the United States Air Force. Using the social ecological framework and content analysis, three focus groups with Airmen were conducted to explore themes at the individual, social, environmental, and organizational/policy level. Overall, results indicated a cohort motivated to achieve good sleep, and also struggling with a number of barriers across each level. This paper highlights opportunities for population health interventions during technical training aimed at supporting Airmen in developing healthy sleep behaviors early in the course of their career.

RESUMEN

BACKGROUND: Alcohol misuse is the fourth leading cause of death in the United States and a significant problem in the US military. Brief alcohol interventions can reduce negative alcohol outcomes in civilian and military populations, but additional scalable interventions are needed to reduce binge and heavy drinking. SMS text messaging interventions could address this need, but to date, no programs exist for military populations. OBJECTIVE: We aimed to develop an SMS text messaging intervention to address binge and heavy drinking among Airmen in Technical Training in the US Air Force. METHODS: We implemented a 2-phase, mixed methods study to develop the SMS text messaging intervention. In phase 1, a total of 149 respondents provided feedback about the persuasiveness of 49 expert-developed messages, preferences regarding message frequency, timing and days to receive messages, and suggested messages, which were qualitatively coded. In phase 2, a total of 283 respondents provided feedback about the persuasiveness of 77 new messages, including those developed through the refinement of messages from phase 1, which were coded and assessed based on the Behavior Change Technique Taxonomy (BCTT). For both phases, mean persuasiveness scores (range 1-5) were calculated and compared according to age (aged <21 or ≥21 years) and gender. Top-ranking messages from phase 2 were considered for inclusion in the final message library. RESULTS: In phase 1, top-rated message themes were about warnings about adverse outcomes (eg, impaired judgment and financial costs), recommendations to reduce drinking, and invoking values and goals. Through qualitative coding of suggested messages, we identified themes related to warnings about adverse outcomes, recommendations, prioritizing long-term goals, team and belonging, and invoking values and goals. Respondents preferred to receive 1 to 3 messages per week (124/137, 90.5%) and to be sent messages on Friday, Saturday, and Sunday (65/142, 45.8%). In phase 2, mean scores for messages in the final message library ranged from 3.31 (SD 1.29) to 4.21 (SD 0.90). Of the top 5 highest-rated messages, 4 were categorized into 2 behavior change techniques (BCTs): valued self-identity and information about health consequences. The final message library includes 28 BCTT-informed messages across 13 BCTs, with messages having similar scores across genders. More than one-fourth (8/28, 29%) of the final messages were informed by the suggested messages from phase 1. As Airmen aged <21 years face harsher disciplinary action for alcohol consumption, the program is tailored based on the US legal drinking age. CONCLUSIONS: This study involved members from the target population throughout 2 formative stages of intervention development to design a BCTT-informed SMS text messaging intervention to reduce binge and heavy drinking, which is now being tested in an efficacy trial. The results will determine the impact of the intervention on binge drinking and alcohol consumption in the US Air Force.

RESUMEN

OBJECTIVE: Chronic kidney disease (CKD) is one of the most common diseases worldwide. The increasing prevalence and incidence of CKD have contributed to the critical problem of high medical costs. Due to stressful environments, aircrew members may have a high risk of renal dysfunction. A better strategy to prevent CKD progression in Air Force personnel would be to diagnosis CKD at an early stage. Since few studies have been conducted in Taiwan to examine the long-term trends in early CKD in Air Force aircrew members, this study is highly important. We investigated the prevalence of CKD and established a predictive model of disease variation among aircrew members. MATERIALS AND METHODS: In this retrospective study, we included all subjects who had received physical examinations at a military hospital from 2004 to 2010 and who could be tracked for four years. The Abbreviated Modification of Diet in Renal Disease Formula (aMDRD) was used to estimate the glomerular filtration rate (GFR) and was combined with the National Kidney Foundation/ Kidney Disease Outcomes Quality Initiative (NKF-K/DOQI) to identify CKD patients. RESULTS: A total of 212 aircrew members were assessed. The results showed that the prevalence of CKD was 3.8%, 9.4%, 9.0%, and 9.4% in each of the four years. According to the logistic regression analysis, abnormal urobilinogen levels, ketones, and white blood cell (WBC) counts in urine and a positive urine occult blood test increased the risk of CKD. A positive urine occult blood test can be used to predict the future risk of CKD. Moreover, the generalized estimating equation (GEE) model showed that a greater risk of CKD with increased examination time, age and seniority had a negative effect. In conclusion, abnormal urobilinogen levels, ketones, and urine WBC counts in urine as well as a positive urine occult blood test might serve as independent predictors for CKD. CONCLUSION: In the future, we can focus not only on annual physical examinations but also on simple and accurate examinations, such as urine occult blood testing, to determine the risk of CKD and prevent its progression in our aircrew members.

RESUMEN

Per- and polyfluoroalkyl substances (PFAS) in the environment pose persistent and complex threats to human and wildlife health. Around the world, PFAS point sources such as military bases expose thousands of populations of wildlife and game species, with potentially far-reaching implications for population and ecosystem health. But few studies shed light on the extent to which PFAS permeate food webs, particularly ecologically and taxonomically diverse communities of primary and secondary consumers. Here we conducted >2000 assays to measure tissue-concentrations of 17 PFAS in 23 species of mammals and migratory birds at Holloman Air Force Base (AFB), New Mexico, USA, where wastewater catchment lakes form biodiverse oases. PFAS concentrations were among the highest reported in animal tissues, and high levels have persisted for at least three decades. Twenty of 23 species sampled at Holloman AFB were heavily contaminated, representing middle trophic levels and wetland to desert microhabitats, implicating pathways for PFAS uptake: ingestion of surface water, sediments, and soil; foraging on aquatic invertebrates and plants; and preying upon birds or mammals. The hazardous long carbon-chain form, perfluorooctanosulfonic acid (PFOS), was most abundant, with liver concentrations averaging >10,000 ng/g wet weight (ww) in birds and mammals, respectively, and reaching as high 97,000 ng/g ww in a 1994 specimen. Perfluorohexanesulfonic acid (PFHxS) averaged thousands of ng/g ww in the livers of aquatic birds and littoral-zone house mice, but one order of magnitude lower in the livers of upland desert rodent species. Piscivores and upland desert songbirds were relatively uncontaminated. At control sites, PFAS levels were strikingly lower on average and different in composition. In sum, legacy PFAS at this desert oasis have permeated local aquatic and terrestrial food webs across decades, severely contaminating populations of resident and migrant animals, and exposing people via game meat consumption and outdoor recreation.

RESUMEN

BACKGROUND: The purpose of this study was to investigate the relationship between sleep quality and gravitational tolerance because sleep could directly affect physiological variables of the human body. METHODS: For the present study, 157 male Korea Air Force Academy cadets were recruited. They were assigned into a gravity (G)-tolerance test pass group (GP, n = 87) and a G-tolerance test fail group (GF, n = 70). All participants were assessed for G-tolerance test and Pittsburgh Sleep Quality Index (PSQI), a self-report questionnaire. Physical fitness test was performed based on the physical fitness test of the Ministry of National Defense of Korea. RESULTS: Independent t-test showed that PSQI global score (p < 0.001), PSQI sleep quality (p < 0.001), PSQI sleep onset latency (p = 0.009), PSQI sleep disturbance (p < 0.001), and PSQI daytime dysfunction (p < 0.001) were significantly different between the two groups. Participants with PSQI score less than 5 were more likely to have a longer G-tolerance test time (OR = 4.705, 95% CI = 2.00-11.05). Additionally, associations between those with PSQI score less than 5 (OR = 4.567, 95% CI = 1.94-10.74) were after adjusting (< 30 s and ≥ 30 s) for covariates. A negative correlation was found between G-tolerance test time and PSQI global score (p < 0.001). Negative correlations were found among 3 km running, push-up (p < 0.001), and sit-up (p < 0.001). A positive correlation was found between push-up and sit-up (p < 0.001). CONCLUSION: In conclusion, participants with good sleep quality were 4.705 times more likely to have longer G-tolerance test time. Thus, it is important for aircraft pilots to manage their sleep quality. Pre-pilots should also improve their sleep quality to pass the G-tolerance test.

RESUMEN

OBJECTIVES: Exertional heat stroke (EHS) remains a significant health concern while training in hot environments, prompting the development of noninvasive wearable technology for monitoring estimated core temperature (ECT). The objective of this study was to review the effectiveness of an ECT device during elite military training by providing a case series of individuals who developed EHS. METHODS: This is a retrospective study of EHS cases during high-intensity training while wearing the ECT device, Zephyr BioharnessTM. Data was collected from January 2021 through September 2021 at the Air Force Special Warfare Training pipeline in San Antonio, TX. Rectal temperatures of EHS diagnoses, defined by central nervous system (CNS) dysfunction and rectal temperature approaching or >40°C (104°F), were compared to ECT reading via Zephyr BioharnessTM. Incidence rates and psychometric properties were calculated using R package. RESULTS: A total of 47,058 daily peak ECT measurements were collected among 1,364 trainees. A total of 499 trainees flagged as potential EHS by Zephyr BioharnessTM reading >39.7°C (103.5°F). The incidence of confirmed EHS was 0.8/1000 person-months. Of the 10 confirmed EHS cases (9 males, 1 female; age = 23.4 ± 2.7 yrs; BMI = 25 ± 2; body fat = 13 ± 5%), 8 trainees had a peak ECT reading below 39.7°C which resulted in a sensitivity of 20%, specificity of 98.9%, positive likelihood ratio (LR) of 18.93 (95% Confidence Interval [CI] 5.5-65.6), and a negative LR of 0.81 (95% CI 0.6-1.1). CONCLUSION: ECT had substantial false positive and negative rates. Further studies are needed to validate this technology in other populations, and the algorithm used in this device needs to be refined to better capture the environmental and physical requirements in the special operations population.

RESUMEN

BACKGROUND: Injuries are a common occurrence in military recruit training, however due to differences in the capture of training exposure, injury incidence rates are rarely reported. Our aim was to determine the musculoskeletal injury epidemiology of military recruits, including a standardised injury incidence rate. METHODS: Epidemiological systematic review following the PRISMA 2020 guidelines. Five online databases were searched from database inception to 5th May 2021. Prospective and retrospective studies that reported data on musculoskeletal injuries sustained by military recruits after the year 2000 were included. We reported on the frequency, prevalence and injury incidence rate. Incidence rate per 1000 training days (Exact 95% CI) was calculated using meta-analysis to allow comparisons between studies. Observed heterogeneity (e.g., training duration) precluded pooling of results across countries. The Joanna Briggs Institute Quality Assessment Checklist for Prevalence Studies assessed study quality. RESULTS: This review identified 41 studies comprising 451,782 recruits. Most studies (n = 26; 63%) reported the number of injured recruits, and the majority of studies (n = 27; 66%) reported the number of injuries to recruits. The prevalence of recruits with medical attention injuries or time-loss injuries was 22.8% and 31.4%, respectively. Meta-analysis revealed the injury incidence rate for recruits with a medical attention injury may be as high as 19.52 injuries per 1000 training days; and time-loss injury may be as high as 3.97 injuries per 1000 training days. Longer recruit training programs were associated with a reduced injury incidence rate (p = 0.003). The overall certainty of the evidence was low per a modified GRADE approach. CONCLUSION: This systematic review with meta-analysis highlights a high musculoskeletal injury prevalence and injury incidence rate within military recruits undergoing basic training with minimal improvement observed over the past 20 years. Longer training program, which may decrease the degree of overload experienced by recruit, may reduce injury incidence rates. Unfortunately, reporting standards and reporting consistency remain a barrier to generalisability. TRIAL REGISTRATION: PROSPERO (Registration number: CRD42021251080).

RESUMEN

Designing polymeric systems with ultra-high optical activity is instrumental in the pursuit of smart artificial chiroptical materials, including the fundamental understanding of structure/property relations. Herein, we report a diacetylene (DA) moiety flanked by chiral D- and L-FF dipeptide methyl esters that exhibits efficient topochemical photopolymerization in the solid phase to furnish polydiacetylene (PDA) with desired control over the chiroptical properties. The doping of the achiral gold nanoparticles provides plasmonic interaction with the PDAs to render asymmetric shape to the circular dichroism bands. With the judicious design of the chiral amino acid ligand appended to the AuNPs, we demonstrate the first example of selective chiral amplification mediated by stereo-structural matching of the polymer-plasmonic AuNP hybrid pairs. Such ordered self-assembly aided by topochemical polymerization in peptide-tethered PDA provides a smart strategy to produce soft responsive materials for applications in chiral photonics.

RESUMEN

Recent comprehensive systematic reviews indicate that females are at greater risk of musculoskeletal injuries (MSKi) than males in military populations. Considering the Canadian Armed Forces (CAF) goal of increasing female representation in the next few years, exploring these trends is essential. We aimed to determine the association between biological sex and MSKi in the CAF. An online survey was conducted with active-duty and former CAF members aged 18-65 years. Sex disparities in MSKi (acute or repetitive strain [RSI]) were analyzed using bivariate associations and binary logistic regressions with significance level at p < 0.05. Analyses were stratified by military environment (i.e., Army, Navy, and Air Force). From the 1947 respondents whose biological sex was reported, 855 were females and 1092 were males. Rates of RSI sustained by females and males while serving were 76.2% and 70.5% (p = 0.011), respectively, whereas 61.4% of females reported acute injuries compared to 63.7% of males (p = 0.346). Females were more likely to report overall RSI (adjusted odds ratio [aOR]: 1.397; 95% confidence intervals [CI]: 1.068-1.829), RSI having a greater impact on daily activities (aOR [95%CI]: 2.979 [2.093-4.239]) and greater impact on career progress/length (aOR [95%CI]: 1.448 [1.066-1.968]). Acute injuries, also more prevalent in females, were reported to have a greater impact on daily activities (aOR [95%CI]: 1.688 [1.198-2.379]). This study highlights sex disparities in MSKi prevalence and outcomes. Females within the CAF sample presented greater likelihood of reporting RSI, perceived impact of RSI on daily activities and career progress/length, and perceived impact of acute injuries on daily activities.

RESUMEN

The Air Force seeks to maximize airman fitness and minimize threats to individual and unit readiness, such as domestic and sexual violence and suicide. The purpose of the Air Force's Task Force True North (TFTN) is to provide effective prevention and treatment programs to airmen in need by embedding health care providers directly into units. In this study, the authors identify potential courses of action (COAs) for expanding the TFTN program, including estimating each approach's associated manpower requirements, recruiting requirements, total costs, and implementation timelines. In developing these COAs, the authors analyzed embedded behavioral and physical health programs in the Army, Navy, Marine Corps, and U.S. Special Operations Command; developed a framework for analyzing mental, physical, and social squadron risk levels; developed personnel packages for low-, medium-, and high-risk squadrons; and estimated the costs of implementing these personnel packages under different timelines. In addition to detailing these COAs, the authors provide recommendations on best practices for the Air Force to follow as it expands the TFTN program.

RESUMEN

Analyses were conducted of reproductive outcomes for conceptions of participants of the Air Force Heath Study. Participants were male Air Force veterans of the Vietnam War. Conceptions were categorized into conceived before and after the start of the participant's Vietnam War service. Analyses accounted for correlation between outcomes for multiple conceptions for each participant. For each of three non-sparsely occurring outcomes, including not live born, miscarriage, and preterm, the probability of occurrence increased substantially when conceived after compared to before the start of Vietnam War service. These results support the conclusion of an adverse effect due to Vietnam War service on these reproductive outcomes. Data for conceptions after the start of Vietnam War service for participants with measured dioxin values were used to estimate dose-response curves for the effect of dioxin exposure on the occurrence of each of the three non-sparsely occurring outcomes. These curves were assumed to be constant up to a threshold and then monotonic after that threshold. For each of the three non-sparsely occurring outcomes, the estimated dose-response curves increased nonlinearly after associated thresholds. These results support the conclusion that the adverse effect due to conception after the start of Vietnam War service is attributable to high enough exposures to dioxin, a toxic contaminant of Agent Orange used for herbicide spraying in the Vietnam War. Sensitivity analyses supported the conclusion that dioxin results were not substantially affected by the assumption of monotonicity, decay due to elapsed time from exposure to measurement, and available covariates.

RESUMEN

U.S. Air Force cyber personnel were faced with changes in their workplace, fitness routines, and personal lives during the COVID19 pandemic. Adjusting to COVID-19-related requirements likely increased the stress of already stressful jobs for military members and their families, which could have resounding impacts on emotional, social, and physical well-being. Therefore, it is important to evaluate psychological health outcomes and self-perceived impacts of the changes presented to cyber personnel because of the COVID-19 pandemic. An online occupational health assessment that included demographics, standardized measures of burnout, psychological distress, and work role strain; health behaviors; and perceived impacts of the COVID-19 pandemic was administered to 1488 cyber personnel. Thirty-two negative themes and 13 positive themes were created from qualitative coding for "How has the COVID-19 pandemic impacted you as an individual?" Of the themes created, 966 (68.5%) reported at least one negative impact and 440 (31.2%) reported at least one positive impact. Top-reported negative impacts were limited face-to-face interactions and loss of personal activities. Negative impacts were associated with negative psychological health outcomes (e.g., psychological distress, exhaustion, cynicism) and work role strain. Action-oriented recommendations are given in the event of another pandemic.

RESUMEN

Analyses were conducted of the occurrence of eight general categories of birth defects and developmental disabilities for children fathered by participants of the Air Force Heath Study (AFHS). Participants were male Air Force veterans of the Vietnam War. Children were categorized into conceived before and after the start of the participant's Vietnam War service. Analyses accounted for correlation between outcomes for multiple children fathered by each of the participants. For each of the eight general categories of birth defects and developmental disabilities, the probability of its occurrence increased substantially for children conceived after compared to before the start of Vietnam War service. These results support the conclusion of an adverse effect on reproductive outcomes due to Vietnam War service. Data for children conceived after the start of Vietnam War service for participants with measured dioxin values were used to estimate dose-response curves for the effect of dioxin exposure on the occurrence of each of the eight general categories of birth defects and developmental disabilities. These curves were assumed to be constant up to a threshold and then monotonic after that threshold. For seven of the eight general categories of birth defects and developmental disabilities, the estimated dose-response curves increased nonlinearly after associated thresholds. These results support the conclusion that the adverse effect to conception after the start of Vietnam War service may be attributable to high enough exposures to dioxin, a toxic contaminant of Agent Orange used for herbicide spraying in the Vietnam War.

RESUMEN

OBJECTIVE: The ejection seat is one of the most important rescue tools for military aircrews. However, the high ejection speeds place high loads on the pilots, which is mainly absorbed by the pilot's spine. The differentiated evaluation of spinal injuries is of particular importance because this has a decisive influence on the further personal life and career of the affected aircrew members. Factors influencing the occurrence of a fracture as well as the impact of a spinal injury on military flight certification have not been addressed sufficiently to date. METHODS: The authors conducted a retrospective evaluation of ejection seat evacuations in German Armed Forces combat aircraft accidents between 1975 and 2021. The total number of aviation accidents with ejection seat initiations and the survived ejections were collected. Accident-specific data and pilot-specific data were collected. In addition, it was evaluated whether aircrew members were recertified for military flight after the accident. The type of spinal injury and the location of the injury were evaluated. In addition to the descriptive statistics, two logistic regression models were developed to assess prediction values of accident- and pilot-specific factors for spine injuries. RESULTS: A total of 103 aircrew members were included in this retrospective analysis. The overall prevalence of spine injuries was 56.3%, and the overall prevalence of spine fractures was 33.0%. In the first regression model analysis, there was no association with pilot flight experience, age, height, weight, BMI, and being diagnosed with a spine fracture. Similarly, aircraft type, altitude, and airspeed were not associated with the occurrence of spine fractures. In the regression model analysis for predictors of rejection in military flight recertification after ejection seat evacuation, lumbar spine fractures were associated with higher odds of being rejected for recertification. CONCLUSIONS: Military aircraft crew members have a high risk of suffering from a spine injury after emergency evacuation using an ejection seat. In the subsequent medical workup, special attention should be paid to the spine, and ideally a consultation with a spine surgeon should be performed. Lumbar spine fractures may have major consequences for military flight certification, and therefore special attention should be paid to successful rehabilitation.

RESUMEN

Background: The military environment is characterized by unpredictable situations, intensive training, demanding workload, and job-associated stressors, which make it highly stressful. Mentorship and mental well-being training could be beneficial to both officers and the new adolescent recruits of the Indian Air Force (IAF). Aim: This study aimed at evaluating the effect of a multi-disciplinary structured training on mentoring and mental well-being among officers and instructors in the IAF. Methods: Seventy IAF officers/instructors underwent a week-long multi-disciplinary structured training program, which was conducted at a tertiary care neuro-psychiatric hospital in South India. A quasi-experimental design with a single-group pre- and post-test was adopted. Outcome measures included a) knowledge on mentorship and mental health and b) self-perceived competence in addressing mental health distress. Results: Post training, there was a statistically significant improvement in scores on mentorship/mental health knowledge and a significant increase in self-perceived competence in addressing mental distress. Conclusion: Mentorship and mental well-being training for officers and instructors in the IAF improved mental health knowledge and self-perceived competence. Therefore, administration of regular and in-depth structured mental health-related training interventions could be beneficial not only to the officers but also to the new recruits/mentees in the IAF.
