Post-traumatic stress disorder among military personnel admitted at the Northwest Command Level Three Military Hospital, Bahir Dar, Ethiopia, 2022: an institution-based cross-sectional study.

Background: Post-traumatic stress disorder (PTSD) is one of the most common mental health problems that military personnel encounter. It could be lifelong and affect every aspect of military personnel, including their mental and physical health, family and social interactions, and their work. However, in Ethiopia, the magnitude and its associated factors have not been well investigated. Objective: This study aimed to determine the prevalence of PTSD and its associated factors among military personnel, who were admitted at the Northwest Command Level Three Military Hospital, Bahir Dar, Northwest, Ethiopia, 2022. Methods: An institution-based cross-sectional study was conducted from 21 June to 21 July 2022, at the Northwest Command Level Three Military Hospital. A computer-generated simple random sampling technique was used to select a total of 627 participants. The 17-item Military Version Checklist was utilized to measure PTSD. The Patient Health Questionnaire, Brief Resilience Coping, and Critical War Zone Experience scale were utilized to measure depression, resilience, and combat exposure, respectively. Descriptive, bivariate, and multivariate binary logistic regressions with odds ratios and a 95% confidence interval were used. The level of significance of the association was determined at a p-value < 0.05. Results: A total of 612 respondents participated, with a response rate of 97.6%. The prevalence of PTSD in this study was 21.9% (95% CI: 18.6, 25.2). In multivariable regression, female sex [adjusted odds ratio (AOR) = 2.3, 95% CI; 1.3, 3.87], combat personnel (AOR = 2.75, 95% CI; 1.44, 6.36), handling dead bodies (AOR = 2.5, 95% CI,1.24, 5.02), having 4-5 deployments (AOR = 2.94, 95% CI, 1.63, 5.32), having ≥6 deployments (AOR = 3.4, 95% CI, 1.95, 6.17), low resilience coping (AOR = 2.02, 95% CI; 1.16, 3.53), poor social support (AOR = 2.46, 95% CI, 1.39, 4.35), very high combat exposures (AOR = 4.8, 95% CI, 2.03, 11.93), and depression (AOR = 2.8, 95% CI, 1.68, 4.67) were significantly associated with PTSD. Conclusion: PTSD is markedly prevalent among the Ethiopian military population, with key risk factors identified as being female, poor social support, low resilience coping skills, handling dead bodies, multiple deployments (four or more), high combat experiences, and depression. Healthcare professionals must prioritize the early diagnosis and intervention of PTSD in vulnerable groups of military personnel.

Cold operational readiness in the military: from science to practice.

Cold weather operations are logistically difficult to orchestrate and extremely challenging for soldiers. Decades of research and empirical evidence indicate that humans are extremely vulnerable to cold and that individual responses are highly variable. In this context, it may be necessary to develop personalised strategies to sustain soldiers' performance and ensure overall mission success in the cold. Systematic cold weather training is essential for soldiers to best prepare to operate during, and recover from, cold weather operations. The purpose of this review is to highlight key aspects of cold weather training, including (1) human responses to cold, (2) nutrition, (3) sleep and (4) protective equipment requirements. Bringing science to practice to improve training principles can facilitate soldiers performing safely and effectively in the cold. Cold weather training prepares soldiers for operations in cold, harsh environments. However, decreases in physical, psychological and thermoregulatory performance have been reported following such training, which influences operational ability and increases the overall risk of injuries. When optimising the planning of field training exercises or operational missions, it is important to understand the soldiers' physical and cognitive performance capacity, as well as their capacity to cope and recover during and after the exercise or mission. Even though the body is fully recovered in terms of body composition or hormonal concentrations, physical or cognitive performance can still be unrecovered. When overlooked, symptoms of overtraining and risk of injury may increase, decreasing operational readiness.

Projections of Disability in the Department of Defense Workforce Through 2031: Estimating Future Assistive Technology Requirements for Department of Defense Civilian Employees and Service Members.

The Department of Defense (DoD) requires both current and projected estimates of the size of its workforce population with specific categories of disabilities. These estimates support the requirements under the Rehabilitation Act of 1973 as well as the goals outlined in multiple executive orders, including Executive Order 14035, directing DoD to hire employees with disabilities and provide them with reasonable accommodations. These estimates are necessary to determine the assistive technology (AT) required and its anticipated costs through 2031. AT also furthers DoD's goals in aiding the recovery and retention of injured service members, as well as the broader DoD and U.S. Department of Veteran Affairs (VA) community in aiding in the post-service employment of service members who are medically separating. Thus, the authors seek to estimate the potential demand for AT from these groups. The authors give projections of the DoD civilian employee population-and of injured and wounded service members-with specific disabilities categorized by DoD's centralized AT procurer (hearing, vision, cognitive, and dexterity disabilities), as well as the potential anticipated requests for AT by these populations and their costs between 2021 and 2031.

Sarin exposure, mortality and cancer incidence in UK military veterans involved in human experiments at Porton Down: 52-year follow-up.

OBJECTIVES: We investigated whether UK military personnel exposed to sarin during the 'Service Volunteer Programme' at Porton Down had increased rates of mortality or cancer incidence over a 52-year follow-up. METHODS: A historical cohort study assembled from UK military records, comprising male veterans exposed to sarin during the 'Service Volunteer Programme' at Porton Down, UK (n=2975) and a comparison group of similar veterans who did not attend (n=2919). Mortality and cancer incidence data were obtained from national registries up to December 2019. Analysis was conducted using Cox regression adjusted for age, year of birth and service characteristics. RESULTS: Over a median follow-up of 52.2 years (range 2 days to 74.6 years), 1598 (53.7%) sarin-exposed veterans and 1583 (54.3%) non-exposed veterans died. Adjusted HRs for all-cause mortality were raised for any sarin exposure (HR=1.08, 95% CI 1.01 to 1.16), two or more exposures (HR=1.25, 95% CI 1.04 to 1.49) and higher doses (air >15 mg.min/m3) (HR=1.15, 95% CI 1.02 to 1.30). For cause-specific mortality, sarin exposure was associated with deaths from 'other' circulatory diseases (excludes ischaemic and cerebrovascular diseases) (HR=1.41, 95% CI 1.06 to 1.87) and alcohol-attributable deaths (HR=2.66, 95% CI 1.40 to 5.07). There was no association between sarin exposure and overall cancer incidence (HR=1.01, 95% CI 0.93 to 1.10), but cancer incidence was higher for alcohol-related neoplasms (HR=1.24, 95% CI 1.01 to 1.51). CONCLUSIONS: Sarin exposure was associated with increased rates of mortality over a 50-year follow-up. The strongest associations were observed for deaths attributable to alcohol and 'other' circulatory diseases.

MDMA for treatment of PTSD and neurorehabilitation in military populations.

BACKGROUND: Neurorehabilitation in military populations is complicated by higher rates of PTSD and unique characteristics of military institutions. These factors can adversely impact the patient-therapist therapeutic alliance and engagement with the rehabilitation process leading to poorer outcomes. MDMA is a non-classical psychedelic with pro-social and fear regulating properties. MDMA-assisted therapy is being explored as a novel treatment for PTSD that potentially offers rapid symptom improvement and enhances therapeutic alliance. OBJECTIVE: A review of MDMA-assisted therapy for PTSD is provided in the context of neurorehabilitation in military populations. The molecular mechanism of MDMA is outlined and a novel application of MDMA for neurorehabilitation is proposed. METHODS: This is an expert review and synthesis of the literature. RESULTS: Results from late-stage clinical trials suggest MDMA-assisted therapy for PTSD would be of particular benefit for military populations with PTSD. The unique pro-social properties of MDMA could be leveraged to enhance the therapeutic alliance and patient engagement during neurorehabilitation. CONCLUSION: The unique qualities and benefits of MDMA and MDMA-assisted therapy for PTSD suggest relevant application in military personnel undergoing neurorehabilitation. There are many similarities in patient-therapist dynamics in PTSD treatment and neurorehabilitation. The properties of MDMA which enhance therapeutic alliance, downregulate fear, and increase cognitive flexibility would potentially benefit both military personnel with and without PTSD undergoing neurorehabilitation.

Chronic Treatment-Resistant Annular Rash: A Case of Neutrophilic Figurate Erythema.

Neutrophilic figurate erythema (NFE) is a rarely reported figurate erythema that clinically presents similarly to erythema annulare centrifugum (EAC) with neutrophil-predominant perivascular and interstitial infiltrate in the dermis on histopathology. We present the case of a 32-year-old active-duty military male who presented with a chronic treatment-resistant skin rash. The rash began on his thighs five years previously and was treated with topical and oral antifungals repeatedly without improvement. The patient was deployed overseas during the rash onset, but the rash persisted upon his return stateside. No triggers were identified. His persistent skin eruption consisted of erythematous polycyclic annular plaques with a "trailing edge" scale. Histologic examination revealed perivascular neutrophils and perivascular and interstitial eosinophils without signs of vasculitis or infection. With only 15 reported cases, it can be difficult to recognize leading to long delays in diagnosis and treatment. Despite having a clinical course similar to EAC, NFE may require anti-neutrophil therapy to resolve completely.

Military Family Physicians' Readiness to Provide Gender-Affirming Care: A Serial Cross-Sectional Study.

PURPOSE: Family physicians are increasingly more likely to encounter transgender and gender-diverse (TGD) patients requesting gender-affirming care. Given the significant health inequities faced by the TGD community, this study aimed to assess changes in military-affiliated clinicians' perspectives toward gender-affirming care over time. METHODS: Using a serial cross-sectional survey design of physicians at the 2016 and 2023 Uniformed Services Academy of Family Physicians conferences, we studied participants' perception of, comfort with, and education on gender-affirming care using Fisher's Exact tests and logistic regression. RESULTS: Response rates were 68% (n = 180) and 69% (n = 386) in 2016 and 2023, respectively. Compared to 2016, clinicians in 2023 were significantly more likely to report receiving relevant education during training, providing care to >1 patient with gender dysphoria, and being able to provide nonjudgmental care. In 2023, 26% reported an unwillingness to prescribe gender-affirming hormones (GAH) to adults due to ethical concerns. In univariable analysis, female-identifying participants were more likely to report willingness to prescribe GAH (OR = 2.6, 95%CI = 1.7-4.1) than male-identifying participants. Willingness to prescribe was also associated with ≥4 h of education (OR = 2.2, 95%CI = 1.1-4.2) compared to those with fewer than 4 h, and those who reported the ability to provide nonjudgmental care compared to those who were neutral (OR = 0.09, 95%CI = 0.04-0.2) or disagreed (OR = 0.11, 95%CI = 0.03-0.39). Female-identifying clinicians were more likely to agree additional training would benefit their practice (OR = 5.3, 95%CI = 3.3-8.5). CONCLUSIONS: Although military-affiliated family physicians endorsed more experience with and willingness to provide nonjudgmental gender-affirming care in 2023 than 2016, profound gaps in patient experience may remain based on the assigned clinician. Additional training opportunities should be available, and clinicians unable to provide gender-affirming care should ensure timely referrals. Future research should explore trends across clinical specialties.

Salivary C-reactive protein exhibits a diurnal pattern and relates to biobehavioral health in military men.

C-reactive protein is a systemic inflammatory biomarker that is positively associated with the development of disease. Salivary C-reactive protein (sCRP) has previously been reported to have a diurnal rhythm with higher levels upon awakening and lower levels thereafter. The aims of this study were to evaluate the stability of sCRP across two days, characterize the daily sCRP pattern, compute morning sCRP parameters, and evaluate associations with biobehavioral health in US Navy Explosive Ordnance Disposal (EOD) technicians. Seventy male EOD technicians (age = 34.9 ± 6.5 years) participated in this study, which included a tablet-based survey, measures of health and fitness, and saliva collection. In a free-living setting, participants self-collected saliva on 2 consecutive days at WAKE, WAKE+30, WAKE+60, 4p.m., and 9p.m., for a total of 10 samples. Parameters (e.g., area under the curve) were computed to characterize the morning sCRP magnitude and pattern. Pearson product-moment correlation analyses were used to assess the stability of sCRP samples and parameters across the study period and to examine associations with biobehavioral health. Average sCRP concentrations for the 2-day period were evaluated using an analysis of variance with repeated measures. The stabilities between corresponding time points on Days 1 and 2 were very high (rs = 0.87-.94, all ps ≤ 0.001). sCRP concentrations were highest at WAKE, decreased by 73.6 % at WAKE+30, and then plateaued for the rest of the day. Parameter stabilities were good to excellent (rs = 0.77-.98, all ps ≤ 0.001). We also observed associations between sCRP parameters, self-reported health behaviors, and objective measures of health and fitness. In this study of a military population, we characterized sCRP as diurnal with robust stability across 2 consecutive days, which demonstrates the feasibility of sCRP as a biomarker. These results have significant implications for study methodology and for using sCRP as a marker of dysfunction or disease.

BMI changes among U.S. Navy and Marine Corps active-duty service members during the COVID-19 pandemic, 2019-2021.

BACKGROUND: The COVID-19 pandemic disrupted the daily life and routines of Americans across the United States (U.S.), including those of our active-duty service members (ADSMs). Limited movement orders enacted during this time to promote social distancing prohibited access to fitness and dining facilities for ADSMs. This study aims to expand on previous work identifying changes in body mass index (BMI) among U.S. Army service members by identifying changes in body mass index (BMI) among active-duty service members from both the Navy and Marine Corps during the same time period. METHODS: We conducted a retrospective cohort study of active-duty service members from the Navy and Marine Corps using data from the Military Health System Data Repository. BMI was calculated and categorized according to CDC guidelines both before (February 2019 - January 2020) and during the pandemic (September 2020 - June 2021). Women who were pregnant or delivered during and one year prior to the study periods were excluded. Statistical analyses included paired t-tests evaluating mean BMI, percent change, and the Stuart-Maxwell test for marginal homogeneity. RESULTS: We identified 98,330 active-duty Sailors and 55,298 active-duty Marines for inclusion in this study. During the pandemic period the percentage of Sailors with Underweight decreased by 11%, Healthy weight decreased by 11.1%, Overweight increased by 2.1%, and the percentage of Sailors with Obesity increased by 16.5%. During this same time period, Marines with Underweight decreased by 1%, Healthy weight decreased by 16%, Overweight increased by 3.0%, and Marines with Obesity increased by 51%. The largest increases in service members with overweight and obesity observed among both cohorts were among female service members, service members under age 20, and service members with a Junior Enlisted rank. CONCLUSIONS: Significant increases in obesity were observed amongst active-duty United States Navy and Marine Corps service members during DoD pandemic mitigation efforts. Increased rates of obesity likely effected fitness and force readiness. Future interventions should be targeted at younger, Junior-Enlisted Marines and Sailors to promote healthy lifestyles and provide education on nutrition, appropriate exercise, sleep hygiene, and stress management.

Impact of life-threatening military incidents during deployments abroad on the relationships between military personnel and their families.

Introduction: The influence of deployments on family relationships has hardly been investigated. Following a recently proposed new research strategy, military personnel with and without deployment-related life-threatening military incidents during deployment were compared. The hypothesis was that partner and family relationships of military personnel who experienced such an event would deteriorate more. Methods: This study included N = 255 military personnel who had a romantic partner (n = 78 of them had children) when deployed to Afghanistan. Of these, n = 68 military personnel experienced a deployment-related critical event during the deployment, n = 187 did not. Partnership quality was assessed using a semi-structured pre- and post-deployment interview. Results: The partner relationships of military personnel who experienced a deployment-related life-threatening military incident during deployment broke up significantly more often. The partner relationships of all military personnel deteriorated significantly, with greater deterioration after deployment in the group who faced such incidents. These results were independent of age, rank or number of previous deployments. In addition, there was a significant deterioration in the relationships between all military personnel and their children with greater deterioration after deployment in the group who faced such incidents. Conclusion: Life-threatening military incidents during a deployment abroad appear to have a considerable influence on the quality and stability of the partner and family relationships of military personnel. These findings can be used to inform the development of specific pre- and post-deployment measures and training.

Why are we doing this Staff? Justification and implications of aerobic fitness testing in the military.

BACKGROUND: Physical fitness is a key tenet of military organisations worldwide. Specifically, many consider aerobic fitness (AF) an essential physical attribute for ensuring optimal military performance and readiness. However, the intricate relationship between AF and various facets of military job performance necessitates comprehensive review to ascertain the appropriateness and effectiveness of its assessment. OBJECTIVE: This narrative review aims to describe the relationship between AF and factors influencing individual military performance and readiness, and explores the implications of the enforcement of in-service, generic AF test standards in military populations. METHODS: Databases (PubMed and Google Scholar) were searched for all relevant published peer-reviewed literature as at August 2023. RESULTS: Inconsistent associations were found between AF and outcomes influencing individual military performance (physical capabilities, cognitive capabilities, presenteeism and productivity, resilience, and technical/tactical capabilities) and readiness (mental health and wellbeing and physical health). Consequently, the level of AF needed for acceptable or optimal military performance remains uncertain. CONCLUSIONS: AF is a cornerstone of health and performance, yet linking generic AF test standards to job performance is complex, with multiple factors interacting to influence outcomes. From existing literatures, there does not appear to be a specific level of AF at, and/or above, which acceptable military performance is achieved. As such, the enforcement of and emphasis on in-service, pass/fail, generic AF test standards in military populations is questionable and requires thoughtful re-evaluation. Role/task-specific AF should be assessed through evidence-based PES and the use of generic AF tests limited to the monitoring and benchmarking of health-related fitness.

A physical demands analysis to identify and delineate critical physical tasks for physically demanding US air force occupations.

BACKGROUND: Military physical fitness tests and standards often lack a scientific basis. Contrary to this traditional-historical precedent, US Air Force researchers use a "Two-Tier" health (Tier 1) and performance (Tier 2) approach to develop evidence-based criterion physical fitness tests, standards, and training. This study specifically and only addresses a physical demands analysis, the first step in a six-step process to develop Tier 2 occupationally specific, operationally relevant physical fitness tests and standards, and training guidance. OBJECTIVE: This study conducted a physical demands analysis to identify and delineate occupationally specific, operationally relevant critical physical tasks for eight physically demanding US Air Force occupational specialties. METHODS: A comprehensive five part physical demands analysis reviewed duty tasks, conducted focus groups, assessed incumbents, observed operational tasks, and interviewed senior leaders to detail critical physical tasks. RESULTS: The physical demands analysis delineated duty tasks to critical physical tasks for Special Tactics (556 to 40), Pararescue (981 to 50), Tactical Air Control (415 to 44), Special Operations Weather (586 to 50), Explosive Ordnance Disposal (1107 to 39), Security Forces (1286 to 25), Fire and Emergency Services (802 to 39), and Survival, Evasion, Resistance, and Escape (1099 to 25). CONCLUSIONS: The study approach proved efficacious for conducting a thorough physical demands analysis to identify and delineate occupationally specific, operationally relevant critical physical tasks for eight US Air Force physically demanding occupations. Critical physical tasks provide basis for the next overall research process step, developing physical task simulations to link to predictive physical fitness tests and training guidance.

Coping style as a risk factor for future alcohol use disorder: A 16-year longitudinal study in a Canadian military sample.

BACKGROUND: Coping strategies used in response to stress have the potential to influence the development of mental health disorders, including alcohol use disorders. The current study investigated whether coping strategies placed an individual at greater likelihood for developing a future alcohol use disorder. METHODS: This study used data from the Canadian Armed Forces Members and Veterans Mental Health Follow-up Survey; a nationally representative 16-year follow-up survey, with initial data collected in the 2002 Canadian Community Health Survey - Canadian Forces Supplement. The total sample from the two datasets included 2941 individuals who were Regular Force members in 2002. Coping styles included problem-focused, avoidant, and self-medication. Adjusted logistic regression analyses examined relationships between coping style (in 2002) and alcohol use disorders (developed between 2002 and 2018). RESULTS: Self-medication coping in 2002 was associated with any alcohol disorder since last interview (i.e., 2002-2018) (AOR 1.26; 95 % CI, 1.02-1.57) and during the past year (adjusted odds ratios [AOR 1.26; 95 % CI, 1.08-1.47]), as well as past-year binge drinking (AOR 1.19; 95 % CI, 1.09-1.29). Problem-focused coping was protective against past-year alcohol abuse (AOR 0.84; 95 % CI, 0.71-1.00) and any alcohol use disorder (AOR 0.87; 95 % CI 0.76-1.00). CONCLUSION: Coping styles were strongly associated with future alcohol use disorders. Notably, results show the risk extended over a 16-year period. Findings suggest the use of self-medicating coping strategies places an individual at increased risk of developing alcohol use disorders, while problem-focused coping may decrease future risk of alcohol use disorders.

Prevalence of burnout among military personnel in the plateau region of China: a cross-sectional survey.

OBJECTIVES: The geographical environment and military activities in the plateau area pose potential work-related stressors for military personnel, leading to burnout which is an external manifestation of internal energy exhaustion caused by stress. Without countermeasures, this can result in serious military problems. This study aims to examine the association between burnout and occupational stressors among military personnel stationed in the plateau area of China. MATERIAL AND METHODS: A stratified randomized cluster sampling survey was conducted among 2026 military personnel from 6 different troops stationed in the plateau area of China. The Chinese Maslach Burnout Inventory-General Survey(MBI-GS in Chinese) was administered from March 2022 to December 2023, and data were analyzed using SPSS version 25. RESULTS: A total of 2026 military personnel participated in the survey. The mean overall burnout score was 3.37 ± 0.73, with emotional exhaustion at 2.69 ± 0.89, depersonalization at 3.58 ± 0.92, and professional achievement at 3.81 ± 0.85 levels respectively reported by participants on average scale scores ranging from zero to six. Severe level of burnout was reported by 43.2% of participants while medium level of burnout was reported by 54 .3%. Age, education level, length of military service, and household income were identified as important factors influencing burnout. CONCLUSION: This study highlights a relatively high prevalence of burnout among military personnel stationed in plateau areas necessitating attention towards their occupational health particularly focusing on working hours and economic aspects so as to formulate effective policies and implement intervention measures that strengthen career development for soldiers deployed in such regions.

Prevalence of smoking among national military service recruits in UAE.

Background: According to the various screening programs conducted, the prevalence of tobacco use among UAE Nationals is high. A considerable increase is also seen in various forms of smoking is seen among young military men during deployment which results in loss of physical health, less productivity, readiness and increased health care utilization. Also smokers are more likely to develop other addictions and chronic medical conditions. Aim: To estimate the prevalence of smoking among national military service recruits in the United Arab Emirates and to find its relation with various factors: socio-demographics, lifestyle, comorbidities, and military environment. Methods: A cross sectional study was conducted amongst national service recruits selected by random stratification through a self-administered anonymized questionnaire which was distributed to a final sample of 369 patients. Data was analyzed using SPSS version 16. Chi square, percentage and frequencies were used to present the data where applicable. A p < 0.05 was considered to be significant. Results: The prevalence of smoking among national military service recruits was 41.6%. As the level of education increased the prevalence of smoking decreased. Smokers with insufficient income, divorced or widowed recruits tend to smoke more as against single and married recruits. Smoking rates were decreased in those who exercise regularly. There was a significant relationship between smoking status and chronic diseases. Smoker gatherings inside military campus encouraged initiation of smoking or its continuity. About half of the smokers were not satisfied with environment at military facilities. Conclusion: Smoking has high prevalence among national service military recruits. For this reason, a goal directed future plan toward screening of smokers among recruits and assigning them to smoking cessation clinics and educational seminars prior to joining the national service is the need of the hour.

Upper Limb Function in People With Upper and Lower Limb Loss 8 Years Postinjury: The Armed Services Trauma Outcome Study (ADVANCE) Cohort Study.

OBJECTIVE: Upper limb (UL) disability in people with UL amputation/s is well reported in the literature, less so for people with lower limb amputation/s. This study aimed to compare UL disability in injured (major trauma) and uninjured UK military personnel, with particular focus on people with upper and lower limb amputation/s. METHODS: A volunteer sample of injured (n = 579) and uninjured (n = 566) UK military personnel who served in a combat role in the Afghanistan war were frequency matched on age, sex, service, rank, regiment, role, and deployment period and recruited to the Armed Services Trauma Rehabilitation Outcome (ADVANCE) longitudinal cohort study. Participants completed the Disability of the Arm, Shoulder, and Hand (DASH) questionnaire, scored from 0 (no disability) to 100 (maximum disability) 8 years postinjury. Mann-Whitney U and Kruskal Wallis tests were used to compared DASH scores between groups. An ordinal model was used to assess the effect of injury and amputation on DASH scores. RESULTS: DASH scores were higher in the group with injuries compared to the group without injuries (3.33 vs 0.00) and higher in people with lower limb loss compared to the group without injuries (0.83 vs 0.00), although this was not statistically significant. In the adjusted ordinal model, the odds of having a higher DASH score was 1.70 (95% CI = 1.18-2.47) times higher for people with lower limb loss compared to the group without injuries. DASH score was not significantly different between people with major and partial UL loss (15.42 vs 12.92). The odds of having a higher DASH score was 8.30 (95% CI = 5.07-13.60) times higher for people with UL loss compared to the uninjured group. CONCLUSION: People with lower limb loss have increased odds of having more UL disability than the uninjured population 8 years postinjury. People with major and partial UL loss have similar UL disability. The ADVANCE study will continue to follow this population for the next 20 years. IMPACT: For the first time, potential for greater upper limb disability has been shown in people with lower limb loss long-term, likely resulting from daily biomechanical compensations such as weight-bearing, balance, and power generation. This population may benefit from prophylactic upper limb rehabilitation, strength, and technique.
