Prevalence and Correlates of Military Sexual Trauma in Service Members and Veterans: Results From the 2018 Canadian Armed Forces Members and Veterans Mental Health Follow-up Survey.

INTRODUCTION: Military sexual trauma (MST) is an ongoing problem. We used a 2002 population-based sample, followed up in 2018, to examine: (1) the prevalence of MST and non-MST in male and female currently serving members and veterans of the Canadian Armed Forces, and (2) demographic and military correlates of MST and non-MST. METHODS: Data came from the 2018 Canadian Armed Forces Members and Veterans Mental Health Follow-up Survey (n = 2,941, ages 33 years + ). Individuals endorsing sexual trauma were stratified into MST and non-MST and compared to individuals with no sexual trauma. The prevalence of lifetime MST was computed, and correlates of sexual trauma were examined using multinomial regression analyses. RESULTS: The overall prevalence of MST was 44.6% in females and 4.8% in males. Estimates were comparable between currently serving members and veterans. In adjusted models in both sexes, MST was more likely among younger individuals (i.e., 33-49 years), and MST and non-MST were more likely in those reporting more non-sexual traumatic events. Among females, MST and non-MST were more likely in those reporting lower household income, non-MST was less likely among Officers, and MST was more likely among those with a deployment history and serving in an air environment. Unwanted sexual touching by a Canadian military member or employee was the most prevalent type and context of MST. INTERPRETATION: A high prevalence of MST was observed in a follow-up sample of Canadian Armed Forces members and veterans. Results may inform further research as well as MST prevention efforts.

Rationale and Methodology of the 2018 Canadian Armed Forces Members and Veterans Mental Health Follow-up Survey (CAFVMHS): A 16-year Follow-up Survey: Raison D'être Et Méthodologie De L'enquête De Suivi Sur La Santé Mentale Des Membres Des Forces Armées Canadiennes Et Des Anciens Combattants, 2018 (ESSMFACM).

OBJECTIVE: Knowledge is limited regarding the longitudinal course and predictors of mental health problems, suicide, and physical health outcomes among military and veterans. Statistics Canada, in collaboration with researchers at the University of Manitoba and an international team, conducted the Canadian Armed Forces Members and Veterans Mental Health Follow-Up Survey (CAFVMHS). Herein, we describe the rationale and methods of this important survey. METHOD: The CAFVMHS is a longitudinal survey design with 2 time points (2002 and 2018). Regular Force military personnel who participated in the first Canadian Community Health Survey Cycle 1.2-Mental Health and Well-Being, Canadian Forces Supplement (CCHS-CFS) in 2002 (N = 5,155) were reinterviewed in 2018 (n = 2,941). The World Mental Health Survey-Composite International Diagnostic Interview was used with the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV) criteria. RESULTS: The CAFVMHS includes 2,941 respondents (66% veterans; 34% active duty) and includes data on mental disorder diagnoses, physical health conditions, substance use, medication use, general health, mental health services, perceived need for care, social support, moral injury, deployment experiences, stress, physical activity, military-related sexual assault, childhood experiences, and military and sociodemographic information. CONCLUSIONS: The CAFVMHS provides a unique opportunity to further understand the health and well-being of military personnel in Canada over time to inform intervention and prevention strategies and improve outcomes. The data are available through the Statistics Canada Research Data Centres across Canada and can be used cross-sectionally or be longitudinally linked to the 2002 CCHS-CFS data.

Lifetime Prevalence and Comorbidity of Mental Disorders in the Two-wave 2002-2018 Canadian Armed Forces Members and Veterans Mental Health Follow-up Survey (CAFVMHS): Prévalence et Comorbidité de Durée de vie Des Troubles Mentaux Dans l'Enquête de Suivi Sur la Santé Mentale Auprès des Membres des Forces Armées Canadiennes et Des ex-Militaires (ESSMFACM) en Deux Cycles de 2002 à 2018.

OBJECTIVE: The current study used the Canadian Armed Forces Members and Veterans Mental Health Follow-up Survey (CAFVMHS) to (1) examine the incidence and prevalence of mental disorders and (2) estimate the comorbidity of mental disorders over the follow-up period. METHOD: The CAFVMHS (2018) is a longitudinal study with two time points of assessment. The sample is comprised of 2,941 Canadian Forces members and veterans who participated in the 2002 Canadian Community Health Survey: Canadian Forces Supplement. The World Health Organization Composite International Diagnostic Interview (WHO-CIDI) was utilized to diagnose Diagnostic and Statistical Manual-IV post-traumatic stress disorder (PTSD), major depressive episode (MDE), generalized anxiety disorder, social anxiety disorder (SAD), and alcohol abuse and dependence. Self-report health professional diagnoses were assessed for attention deficit hyperactivity disorder (ADHD), mania, obsessive compulsive disorder (OCD), and personality disorder. We established weighted prevalence of mental disorders and examined the association between mental disorders using logistic regression. RESULTS: In 2018, lifetime prevalence of any WHO-CIDI-based or self-reported mental disorder was 58.1%. Lifetime prevalence of any mood or anxiety disorder or PTSD was 54.0% in 2018. MDE (39.9%), SAD (25.7%), and PTSD (21.4%) were the most common mental disorders. There was a substantial increase in new onset or recurrence/persistence of mental disorders between the two measurement points (16-year assessment gap); 2002-2018 period prevalences were 43.5% for mood and anxiety disorder and 16.8% for alcohol abuse or dependence. The prevalence of self-reported ADHD, OCD, any personality disorder, and mania were 3.3%, 3.0%, 0.8%, and 0.8%, respectively. Comorbidity between mental disorders increased over the follow-up. CONCLUSIONS: This study demonstrates a high burden of mental disorders among a large Canadian military and veteran cohort. These findings underscore the importance of prevention and intervention strategies to reduce the burden of mental disorders and alcohol use disorders in these populations.

Health care access and use among male and female Canadian Armed Forces veterans.

BACKGROUND: Veterans are more likely than other Canadians to have chronic health conditions, making access to health care an important issue. However, little research has addressed health care access and use among veterans. This paper examines access and use among veterans compared with other Canadians. DATA AND METHODS: Health care access and use indicators were examined for Regular Force veterans using the 2016 Life After Service Survey. Information for male and female veterans was compared with information on the Canadian general population from the 2015 and 2016 Canadian Community Health Survey, using age-adjusted rates and 95% confidence intervals. RESULTS: More than 80% of male and female veterans reported having a regular medical doctor in the 12 months before the survey. The majority of veterans (71% of males and 81% of females) had consulted a family doctor, while a minority had been hospitalized (8% of males and females). These rates were similar to those in the Canadian general population. However, veteran consultation rates for mental health care and with audiologists, speech therapists or occupational therapists among both sexes were double to triple those of the Canadian general population. Among veterans, males reported lower rates of unmet needs compared with females. DISCUSSION: Veterans had similar rates of access to a regular medical doctor and higher rates of use compared with other Canadians. However, these may be comparatively low, given previous findings on higher rates of disability and some chronic conditions among veterans. Noted differences between males and females highlight the importance of research and services that account for sex and gender. The extent to which health care needs explain health care use and barriers to care requires further research.

Predictors of Retirement Voluntariness Using Canadian Longitudinal Study on Aging Data.

Objectives: Involuntary exit from the labor force can lead to poor health and well-being outcomes. Therefore, the purpose of this research is to better understand the factors that contribute to perceived retirement voluntariness. Methods: We conducted descriptive and multivariable logistic regression analyses using a sample of recent retirees (n = 2080) from the Canadian Longitudinal Study on Aging (CLSA). Results: More than one-quarter (28%) of older workers perceived their retirement to be involuntary. Among 37 possible predictors, 14 directly predicted retirement voluntariness and many more indirectly predicted retirement voluntariness. Only four direct predictors were common to both women and men, retiring because of organizational restructuring/job elimination; disability, health, or stress; financial possibility; and having wanted to stop working. Discussion: Findings suggest the need for employment support, health promotion, work disability prevention, financial education, and support that is sensitive to the differences between women and men to prevent involuntary retirement.

Lessons Learned From Presumptive Condition Lists in Veteran Compensation Systems.

Presumptive condition lists formally accept connections between military factors and veteran health conditions. An environmental scan of such lists and their evidentiary basis was conducted across four veterans' administrations to inform other administrations considering the development of such lists. Information on included conditions, qualifying military factors, and scientific processes was obtained through targeted internet searches and correspondence with veterans' administrations. The content of presumptive condition lists across jurisdictions varied by conditions included, as well as military eligibility requirements (e.g., service in particular conflict, context, or time period). Scientific review processes to develop lists also varied across jurisdictions. Findings indicate that evidence and experience may be leveraged across compensation systems (veteran and civilian). Ongoing research to understand links between military exposures and veteran health is recommended.

Considering Exposure Assessment in Epidemiological Studies of Chronic Health in Military Populations.

Exposure assessment is an important factor in all epidemiological research seeking to identify, evaluate, and control health risks. In the military and veteran context, population health research to explore exposure-response links is complicated by the wide variety of environments and hazards encountered during active service, long latency periods, and a lack of information on exposures in potentially vulnerable subgroups. This paper summarizes some key considerations for exposure assessment in long-term health studies of military populations, including the identification of hazards related to military service, characterization of potentially exposed groups, exposure data collection, and assignment of exposures to estimate health risks. Opportunities and future directions for exposure assessment in this field are also discussed.

Roles of physical and mental health in suicidal ideation in Canadian Armed Forces Regular Force veterans.

OBJECTIVES: Suicide in recent veterans is an international concern. An association between mental disorders and suicide has been established, but less information is available about an association between physical health problems and suicide among veterans. This study extends this area of inquiry by examining the relationship of both physical and mental health problems with suicidal ideation in a representative national sample of Canadian veterans. METHODS: Subjects were a stratified random sample of 2,658 veterans who had been released from the Canadian Armed Forces Regular Force during 1998-2007 and had participated in the 2010 Survey on Transition to Civilian Life. Associations between physical and mental health and past-year suicidal ideation were explored in multivariable regression models using three measures of physical and mental health. RESULTS: The prevalence of suicidal ideation was 5.8% (95% confidence interval [CI]: 5.0%-6.8%). After adjustment for covariates, ideation was associated with gastrointestinal disorders (adjusted odds ratio [AOR] 1.66, CI: 1.03-2.65), depression or anxiety (AOR 5.06, CI: 2.97-8.62) and mood disorders (AOR 2.91, CI: 1.67-5.07); number of physical (AOR 1.22, CI: 1.05-1.42) and mental conditions (AOR 2.32, CI: 2.01-2.68); and SF-12 Health Survey physical health (AOR 0.98, CI: 0.96-0.99 for each 1 point increase) and mental health (AOR 0.88, CI: 0.87-0.89). CONCLUSIONS: Physical health was independently associated with suicidal ideation after adjustment for mental health status and socio-demographic characteristics. The findings underscore the importance of considering physical health in population-based suicide prevention efforts and in mitigating suicide risk in individual veterans.

Postmilitary adjustment to civilian life: potential risks and protective factors.

BACKGROUND: Adjustment to civilian life in Canadian veterans after release from military service has not been well studied. OBJECTIVES: The objectives of this study were: (1) to explore dimensions of postmilitary adjustment to civilian life and (2) to identify demographic and military service characteristics associated with difficult adjustment. DESIGN: Data were analyzed from a national sample of 3,154 veterans released from the regular Canadian Forces during 1998 to 2007 in a cross-sectional survey conducted in 2010 called the Survey on Transition to Civilian Life. METHODS: The prevalence of difficult adjustment to civilian life for selected characteristics was analyzed descriptively, and confidence intervals were calculated at the 95% level. Multivariable logistic regression analysis was used to identify characteristics available at the time of release that were associated with difficult adjustment. RESULTS: The prevalence of difficult adjustment to civilian life was 25%. Statistically significant differences were found across indicators of health, disability, and determinants of health. In multivariable regression, lower rank and medical, involuntary, mid-career, and Army release were associated with difficult adjustment, whereas sex, marital status, and number of deployments were not. LIMITATIONS: Findings cannot be generalized to all veterans because many characteristics were self-reported, important characteristics may have been omitted, and causality and association among health, disability, and determinants of health characteristics could not be determined. CONCLUSIONS: Postmilitary adjustment to civilian life appears to be multidimensional, suggesting the need for multidisciplinary collaboration between physical therapists and other service providers to mitigate difficult transition. Potential risk and protective factors were identified that can inform interventions, outreach strategies, and screening activities, as well as further research.

Out of the shadows: mental health of Canadian armed forces veterans.

In the past 15 years in Canada, as in other nations, the mental health of veterans has emerged as a key concern for both government and the public. As mental health service enhancement unfolded, the need for wider population studies became apparent. This paper describes the renewal of services and key findings from national surveys of serving personnel and veterans.

Health-related quality of life of Canadian Forces veterans after transition to civilian life.

OBJECTIVES: Describe health-related quality of life (HRQoL) of former Canadian Forces (CF) men and women in uniform (Veterans) after transition to civilian life, and compare to age- and sex-adjusted Canadian norms. METHODS: The 2010 Survey on Transition to Civilian Life was a national computer-assisted telephone survey of CF Regular Force personnel who released during 1998-2007. HRQoL was assessed using the SF-12 Physical (PCS) and Mental (MCS) Component Summary scores. Descriptive analysis of HRQoL was conducted for socio-demographic, health, disability and determinants of health characteristics. RESULTS: Mean age was 46 years (range 20-67). Compared to age- and sex-adjusted Canadian averages, PCS (47.3) was low and MCS was similar (52.0). PCS and MCS were variably below average for middle age groups and lowest for non-commissioned ranks, widowed/divorced/separated, 10-19 years of service, physical and mental health conditions, disability, dissatisfaction with finances, seeking work/not working, low social support and difficulty adjusting to civilian life. Among Veterans Affairs Canada clients, 83% had below-average physical PCS, 49% had below-average MCS, and mean PCS (38.2) was significantly lower than mean MCS (48.3). CONCLUSIONS: HRQoL varied across a range of biopsychosocial factors, suggesting possible protective factors and vulnerable subgroups that may benefit from targeted interventions. These findings will be of interest to agencies supporting Veterans in transition to civilian life and to researchers developing hypotheses to better understand well-being in Canadian Veterans.
