Child Maltreatment History, Deployment-Related Traumatic Events, and Past 12-Month Cannabis Use Among Veterans in Canada.

OBJECTIVE: Cannabis use among veterans in Canada is an understudied public health priority. The current study examined cannabis use prevalence and the relationships between child maltreatment histories and deployment-related traumatic events (DRTEs) with past 12-month cannabis use including sex differences among Canadian veterans. METHOD: Data were drawn from the 2018 Canadian Armed Forces Members and Veterans Mental Health Follow-up Survey (response rate 68.7%; veterans only n = 1,992). Five child maltreatment types and 9 types of DRTEs were assessed in relation to the past 12-month cannabis use. RESULTS: The prevalence of lifetime and past 12-month cannabis use was 49.4% and 16.7%, respectively. Females were less likely than males to report lifetime cannabis use (41.9% vs. 50.4%; odds ratio [OR] 0.71; 95% CI, - 0.59 to 0.86). No sex differences were noted for past 12-month cannabis use (14.1% vs. 17.0%; OR 0.80; 95% CI, 0.60 to 1.07). Physical abuse, sexual abuse, neglect, any child maltreatment, most individual DRTEs, and any DRTE were associated with increased odds of past 12-month cannabis use after adjusting for sociodemographic and military variables. Some models were attenuated and/or nonsignificant after further adjustments for mental disorders and chronic pain conditions. Sex did not statistically significantly moderate these relationships. Cumulative effects of having experienced both child maltreatment and DRTEs compared to DRTEs alone increased the odds of past 12-month cannabis use. Statistically significant interaction effects between child maltreatment history and DRTE on cannabis use were not found. CONCLUSIONS: Child maltreatment histories and DRTEs increased the likelihood of past 12-month cannabis use among Canadian veterans. A history of child maltreatment, compared to DRTEs, indicated a more robust relationship. Understanding the links between child maltreatment, DRTEs, and cannabis use along with mental disorders and chronic pain conditions is important for developing interventions and improving health outcomes among veterans.

The Canadian Longitudinal Study on Aging: A Vehicle for Research on Aging in Older Veterans.

INTRODUCTION: Research on the health of older Veterans in Canada is an emerging area. Few population-based studies in Canada have included older Veterans as a specific group of interest. This paper describes a cohort of self-identified Veterans within the Canadian Longitudinal Study on Aging (CLSA). MATERIALS AND METHODS: Using data from the CLSA baseline assessment (2011-2015), we describe sociodemographic and health characteristics along with military-related variables in a cohort of Veterans in Canada. We also estimate the number of Canadian and non-Canadian Veterans living in Canada at the time of the CLSA baseline data collection. RESULTS: We estimate that at the CLSA baseline, there were 718,893 (95% confidence interval [CI], 680,033-757,110) Canadian Veterans and 185,548 (95% CI, 165,713-205,100) non-Canadian Veterans aged 45-85 years living in Canada. Veterans were older and predominantly male compared to non-Veterans in the CLSA. Following age and sex adjustment, the distribution of sociodemographic and health characteristics was similar across all groups. The majority (> 85%) of participants in each comparison group reported self-rated general and mental health as excellent, very good, or good. Following age and sex adjustment, most characteristics across groups remained similar. One exception was mental health, where a greater proportion of Veterans screened positive for depression and anxiety relative to non-Veterans. CONCLUSIONS: Using CLSA baseline data, we estimate the number of older Veterans in Canada and present descriptive data that highlight interesting differences and similarities between Veterans and non-Veterans living in Canada. Canadian and non-Canadian Veterans in the CLSA are presented separately, with the latter group having not been previously studied in Canada. This paper presents a snapshot of a cohort of self-identified Veterans within the CLSA at study baseline and highlights the potential of the CLSA as a vehicle for studying the aging Veteran population in Canada for years to come.

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.

Cluster analysis of Canadian Armed Forces veterans living with chronic pain: Life After Service Studies 2016.

Objective: This study explored the heterogeneity of Canadian Armed Forces veterans living with chronic pain to inform service needs planning and research using cluster analysis. Design: We used a national cross-sectional Statistics Canada population survey. Participants: Participants included 2754 Canadian Armed Forces (CAF) Regular Force veterans released from service between 1998 and 2015 and surveyed in 2016. Methods: We used cluster analysis of veterans with chronic pain based on pain severity, mental health, and activity limitation characteristics. We compared clusters for sociodemographic, health, and service utilization characteristics. Results: Of 2754 veterans, 1126 (41%) reported chronic pain. Veterans in cluster I (47%) rarely had severe pain (2%) or severe mental health problems (8%), and none had severe activity limitations. Veterans in cluster II (26%) more often than veterans in cluster I but less often than veterans in cluster III endorsed severe pain (27%) and severe mental health problems (22%) and were most likely to report severe activity limitation (91%). Veterans in cluster III (27%) were most likely to report severe pain (36%) and severe mental health problems (96%), and a majority reported severe activity limitations (72%). There was evidence of considerable heterogeneity among individuals in terms of socioeconomic characteristics, pain characteristics, mental and physical health status, activity limitations, social integration, and service utilization indicators. Conclusions: About half of Canadian veterans living with chronic pain infrequently endorse severe pain or serious mental health issues without severe activity limitations. The other half had more complex characteristics. The heterogeneity of CAF veterans with chronic pain emphasizes the need for support systems that can address variability of needs.

Objectif: Cette étude portait sur l'hétérogénéité des anciens combattants des Forces armées canadiennes vivant avec la douleur chronique pour éclairer la planification et la recherche en matière de besoins de services à l'aide de l'analyse par groupes.Devis: Nous avons utilisé une enquête nationale transversale sur la population de Statistique Canada.Participants: Les participants comprenaient 2 754 anciens combattants de la Force régulière des Forces armées canadiennes (FAC) libéré du service entre 1998 et 2015 et enquêtés en 2016.Méthodes: Nous avons utilisé une analyse par groupes d'anciens combattants souffrant de douleur chronique fondée sur l'intensité de la douleur, la santé mentale et les caractéristiques en matière de limitation d'activité. Nous avons comparé les caractéristiques sociodémographiques, de santé et d'utilisation des services des groupes.Résultats: Sur 2 754 anciens combattants, 1 126 (41 %) ont fait état d'une douleur chronique. Les anciens combattants du groupe I (47 %) avaient rarement une douleur intense (2 %) ou de graves problèmes de santé mentale (8 %), et aucun d'entre eux n'avait de limitation d'activité sévère. Les anciens combattants du groupe II (26%) souffraient de douleur intense (27 %) et de problèmes de santé mentale graves (22 %) plus souvent que les anciens combattants du groupe I mais moins souvent que les anciens combattants du groupe III et étaient plus susceptibles de déclarer une limitation d'activité sévère (91 %). Les anciens combattants du groupe III (27 %) étaient les plus susceptibles de déclarer une douleur intense (36 %) et des problèmes de santé mentale graves (96 %), et la majorité d'entre eux a signalé une limitation d'activité grave (72%). Les données probantes ont révélé une hétérogénéité considérable parmi les individus en ce qui concerne les indicateurs relatifs aux caractéristiques socioéconomiques, aux caractéristiques de la douleur, à l'état de santé mentale et physique, à la limitation d'activité, à l'intégration sociale et à l'utilisation des services.Conclusions: Environ la moitié des anciens combattants canadiens vivant avec une douleur chronique souffrent rarement de douleur intense ou de problèmes de santé mentale graves sans avoir de limitations d'activité graves. L'autre moitié avait des caractéristiques plus complexes. L'hétérogénéité des vétérans des FAC souffrant de douleur chronique souligne l'importance que des systèmes de soutien capables de répondre à la diversité des besoins soient disponibles.

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.

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.

Prevalence of chronic musculoskeletal pain among active and retired military personnel: a systematic review protocol.

OBJECTIVE: The objective of this review is to assess the prevalence of musculoskeletal chronic pain among active and retired members of military forces and to characterize potential factors that could influence the frequency of musculoskeletal chronic pain. INTRODUCTION: Inherent to military occupations is a diverse source of occupational hazards that affect the well-being of individuals at any stage of their military career (active and retired). Chronic pain may result from the continuous exposure to physically demanding tasks and other risks. Moreover, chronic pain has been associated with other comorbidities, including mental health conditions. INCLUSION CRITERIA: Scientific papers in French or English reporting on chronic pain derived from a musculoskeletal cause in active and retired military personnel will be considered. There will be no restriction on participants' country, age, or length of service. METHODS: The published literature will be identified by exploring biomedical, pharmacological, and physiology bibliographic databases. The unpublished literature will be located through the search of thesis and gray literature repositories. This review will follow the condition-context-population approach and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. The extracted data will include any detail about the anatomic location, diagnosis, types of studies, and risk factors. The review will follow JBI methods of critical appraisal, data extraction, and data synthesis for reviews containing prevalence data. If enough evidence is found, meta-regression analysis will performed, otherwise a narrative review will be completed. SYSTEMATIC REVIEW REGISTRATION NUMBER: PROSPERO CRD42020153704.

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.

Characterization of occupational, demographic and health determinants in Canadian reservists veterans and the relationship with poor self-rated health.

BACKGROUND: Self-rated health is an useful indicator of the general health in specific populations and used to propose interventions after service in the military context. However, there is scarce literature about self- rated health (SRH) in the Canadian Veterans of the Reserve Force and its relationship with demographic, health and occupational characteristics of this specific group. The aims of this research were to determine the SRH in Canadian Reserve Force Veterans and to explore the relationship between demographic, military service and health factors by reserve class. METHODS: Data from the individuals was collected from the Life After Service (LASS) 2013 survey, including Veterans with Reserve Class C (n = 922) and Class A/B (n = 476). Bivariate and multivariate analysis using logistic regression models, were used to assess the association between the demographic characteristics, physical health, mental health, and military service characteristics and the self-rate health by both reserve classes. RESULTS: The overall prevalence of poor SRH in Reserve Class C Veterans was 13.1% (CI:11.08-15.4) and for Reserve Class A/B was 6.9% (CI:5.0-9.1). Different degrees of associations were observed during the bivariate analysis and two different models were produced for each reserve class. Veterans of Reserve Class C showed that being single was (OR = 2.76, CI: 1.47-5.16), being 50-59 years old (OR = 4.6, CI: 1.28-17.11), reporting arthritis (OR = 2.49, CI: 1.33-4.67), back problems (OR = 3.02, CI:1.76-5.16), being obese (OR = 1.96, CI: 1.13-3.38), depression (OR = 2.34, CI: 1.28-4.20), anxiety (OR = 4.11, CI: 2.00-8.42), PTSD (OR = 2.1 CI: 0.98-4.47), PTSD (OR = 20.9, CI:0.98-4.47) and being medically released (OR = 4.48, CI: 2.43-8.24) were all associated with higher odds of poor SRH. The Reserve Class A/B model showed that completing high school (OR = 4.30, CI: 1.37-13.81), reporting arthritis (6.60, CI: 2.15-20.23), diabetes (OR = 11.19, CI: 2.72-46.0), being obese (OR = 3.37, CI: 1.37-8.27), daily smoking (OR = 2.98, CI: 1.05-8.38), having anxiety (OR = 9.8, CI: 3.70-25.75) were associated with higher odds of poor SRH. CONCLUSIONS: These results suggested that the relationship of poor SRH with demographic, health and military occupation domains varied depending on the class on the Reserve Force Service. Different strengths of association showed different risk compositions for both populations. This can be used to better understand the health and well-being of Veterans of the Reserve Force.

The Canadian Forces Cancer and Mortality Study II: a longitudinal record-linkage study protocol.

BACKGROUND: Military service exposes personnel to unusual situations with unclear health-related implications, and to identify both immediate and delayed risks, part of health surveillance includes examination of mortality and cancer rates that extends beyond periods of military service. The main aim of the Canadian Forces Cancer and Mortality Study II (CFCAMS II) is to describe the mortality and cancer experience of Canadian Armed Forces personnel (serving and released; about 230 000 people), with the further aim of informing health promotion and prevention programs for serving personnel and services for veterans after they leave the military. METHODS: This protocol is for a retrospective cohort study of serving and released Canadian Armed Forces personnel who enrolled on or after Jan. 1, 1976 in the Regular Force or Class C of the Reserve Force. To create our cohort, we identified record-linkage methods as the most appropriate mechanism to study mortality and cancer in those with a history of Canadian military service. Statistics Canada will link the CFCAMS II cohort file to the Canadian Vital Statistics (Mortality) and Canadian Cancer Registry databases for outcomes up to Dec. 31, 2014. The linkage will be stored in their highly secure linkage environment. Statistical analyses will be broadly divided into mortality and cancer incidence. RESULTS: We will quantify mortality and cancer morbidity incidence and survival using multiple established methods, as well as age-period-cohort regression models to describe the relation between military service and mortality and cancer outcomes. INTERPRETATION: The findings will represent novel and sound evidence on the risks and protective factors of military life.

Understanding future needs of Canadian veterans.

BACKGROUND: Planning for the future needs of Canadian veterans requires comprehensive and detailed data on the size of the Canadian veteran population and their health. This article describes current veteran population estimates and examines the health of two eras of veterans compared with the health of Canadians in general. DATA AND METHODS: This study describes the size and age structure of the Canadian veteran population forecasted by Veterans Affairs Canada (VAC). Veteran health was examined for two eras of Regular Force veterans. The health of earlier-era veterans (released between 1954 and 2003) was examined using the 2003 Canadian Community Health Survey. The health of recent-era veterans (released between 1998 and 2012) was examined using the 2013 Life After Service Survey. Health indicators for veterans were compared with the Canadian general population using age- and sex-adjusted rates and confidence intervals. RESULTS: The VAC forecast points to a stable population of about 600,000 veterans for the next decade, but a growing proportion will be older than 70 years old. Regular Force veterans of both eras had a higher prevalence than the Canadian general population of activity limitations and back problems, a lower prevalence of low income, and a similar prevalence of life stress and heavy drinking. Recent-era veterans had a higher prevalence than the Canadian general population of many more indicators-in particular, arthritis, self-rated mental health, depression and anxiety. DISCUSSION: Veterans differed from the Canadian general population in many areas of well-being, and recent-era veterans differed in more areas than earlier-era veterans. These results highlight the need for forecasting and planning, and for policy that is sensitive to these differences and incorporates health status changes as veterans age. Multiple data sources will be required to describe the future health needs of the entire Canadian veteran population.

The Canadian Chronic Disease Surveillance System: A model for collaborative surveillance.

Chronic diseases have a major impact on populations and healthcare systems worldwide. Administrative health data are an ideal resource for chronic disease surveillance because they are population-based and routinely collected. For multi-jurisdictional surveillance, a distributed model is advantageous because it does not require individual-level data to be shared across jurisdictional boundaries. Our objective is to describe the process, structure, benefits, and challenges of a distributed model for chronic disease surveillance across all Canadian provinces and territories (P/Ts) using linked administrative data. The Public Health Agency of Canada (PHAC) established the Canadian Chronic Disease Surveillance System (CCDSS) in 2009 to facilitate standardized, national estimates of chronic disease prevalence, incidence, and outcomes. The CCDSS primarily relies on linked health insurance registration files, physician billing claims, and hospital discharge abstracts. Standardized case definitions and common analytic protocols are applied to the data for each P/T; aggregate data are shared with PHAC and summarized for reports and open access data initiatives. Advantages of this distributed model include: it uses the rich data resources available in all P/Ts; it supports chronic disease surveillance capacity building in all P/Ts; and changes in surveillance methodology can be easily developed by PHAC and implemented by the P/Ts. However, there are challenges: heterogeneity in administrative databases across jurisdictions and changes in data quality over time threaten the production of standardized disease estimates; a limited set of databases are common to all P/Ts, which hinders potential CCDSS expansion; and there is a need to balance comprehensive reporting with P/T disclosure requirements to protect privacy. The CCDSS distributed model for chronic disease surveillance has been successfully implemented and sustained by PHAC and its P/T partners. Many lessons have been learned about national surveillance involving jurisdictions that are heterogeneous with respect to healthcare databases, expertise and analytical capacity, population characteristics, and priorities.

Pain in Canadian Veterans: analysis of data from the Survey on Transition to Civilian Life.

BACKGROUND: Little is known about the prevalence of chronic pain among Veterans outside the United States. OBJECTIVE: To describe the prevalence of chronic pain and associated sociodemographic, health behaviour, employment/income, disability, and physical and mental health factors in Canadian Veterans. METHODS: The 2010 Survey on Transition to Civilian Life included a nationally representative sample of 3154 Canadian Armed Forces Regular Force Veterans released from service between 1998 and 2007. Data from a telephone survey of Veterans were linked with Department of National Defence and Veterans Affairs Canada administrative databases. Pain was defined as constant/reoccurring pain (chronic pain) and as moderate/severe pain interference with activities. RESULTS: Forty-one percent of the population experienced constant chronic pain and 23% experienced intermittent chronic pain. Twenty-five percent reported pain interference. Needing help with tasks of daily living, back problems, arthritis, gastrointestinal conditions and age ≥ 30 years were independently associated with chronic pain. Needing help with tasks of daily living, back problems, arthritis, mental health conditions, age ≥ 30 years, gastrointestinal conditions, low social support and noncommissioned member rank were associated with pain interference. CONCLUSIONS: These findings provide evidence for agencies and those supporting the well-being of Veterans, and inform longitudinal studies to better understand the determinants and life course effects of chronic pain in military Veterans.

Disability correlates in Canadian Armed Forces Regular Force Veterans.

PURPOSE: This study was undertaken to inform disability mitigation for military veterans by identifying personal, environmental, and health factors associated with activity limitations. METHOD: A sample of 3154 Canadian Armed Forces Regular Force Veterans who were released during 1998-2007 participated in the 2010 Survey on Transition to Civilian Life. Associations between personal and environmental factors, health conditions and activity limitations were explored using ordinal logistic regression. RESULTS: The prevalence of activity reduction in life domains was higher than the Canadian general population (49% versus 21%), as was needing assistance with at least one activity of daily living (17% versus 5%). Prior to adjusting for health conditions, disability odds were elevated for increased age, females, non-degree post-secondary graduation, low income, junior non-commissioned members, deployment, low social support, low mastery, high life stress, and weak sense of community belonging. Reduced odds were found for private/recruit ranks. Disability odds were highest for chronic pain (10.9), any mental health condition (2.7), and musculoskeletal conditions (2.6), and there was a synergistic additive effect of physical and mental health co-occurrence. CONCLUSIONS: Disability, measured as activity limitation, was associated with a range of personal and environmental factors and health conditions, indicating multifactorial and multidisciplinary approaches to disability mitigation.

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.

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.
