Comparing negative health indicators in male and female veterans with the Canadian general population

Abstract

Introduction

Sex-based information on differences between Canadian veterans and the general population is important to understand veterans’ unique health needs and identify areas requiring further research. This study compared various health indicators in male and female veterans with their Canadian counterparts.

Methods

Health indicators for recent-era Regular Force veterans (released between 1998 and 2015) were obtained from the 2016 Life After Service Survey and compared with the general population in the 2015–16 Canadian Community Health Survey using a cross-sectional approach. Age-adjusted rates and 95% CIs were calculated for males and females separately.

Results

Compared with Canadians, veterans (both sexes) reported higher prevalence of fair or poor health and mental health, needing help with one or more activity of daily living, lifetime suicidal ideation and being diagnosed with mood and anxiety disorders, post-traumatic stress disorder, migraines, back problems, chronic pain, arthritis, ever having cancer, hearing problems, chronic pain and gastrointestinal problems. A higher prevalence of cardiovascular disease (all types) and high blood pressure was observed in male veterans compared with their Canadian counterparts. Within veterans only, males reported a higher prevalence of diagnosed hearing problems and cardiovascular disease compared with females; conversely females reported a higher prevalence of diagnosed migraines, mood, anxiety and gastrointestinal disorders, and needing help with activities of daily living. These sex differences are similar to the Canadian general population. Some similarities in reporting prevalence between male and female veterans (eg, fair or poor mental health, lifetime suicidal ideation, arthritis, asthma, lifetime cancer incidence, chronic pain and diabetes) were not observed in other Canadians.

Conclusion

Male and female veterans differed from comparable Canadians, and from each other, in various areas of health. Further research is needed to explore these findings, and veteran-based policies and services should consider sex differences.

Key messages.

• Veterans represent approximately 3% of the Canadian adult population.

• Females represent an increasing proportion of military members globally with expanding roles in combat-related activities.

• While certain health outcomes in veterans have been researched and recognised, a limited literature base is available to describe other aspects of their physical and mental well-being, particularly stratified by sex.

• Both male and female veterans report a higher prevalence of many negative health conditions relative to their Canadian counterparts.

• Similarities in outcomes between male and female veterans underline a common experience of military service and its associated hazards; differences may reflect sex-based and gender-based factors noted elsewhere in the occupational health literature.

• Research and policies to support the health of veterans should consider sex differences.

Introduction

In Canada, veterans (former officers or non-commissioned members of the Canadian Armed Forces, Regular or Reserve) represent approximately 3% of the adult population.¹ A number of physical, lifestyle, psychological and exposure factors encountered during military service,² and through the transition to civilian life,³ may contribute to long-term health and well-being effects that have not been comprehensively characterised in veterans. To date, the only national-level survey that has identified veterans and permitted health-based comparisons with the general population by sex is the 2003 Canadian Community Health Survey (CCHS), a large and nationally representative survey of the Canadian population.¹ Veterans differed from their Canadian counterparts in many areas of health and well-being, including chronic conditions, mental health conditions and disability.

Assessments of veterans’ health, and comparisons with the general Canadian population, should be regularly updated to inform research and planning for veterans’ current and future needs. It is also important to investigate male and female veterans’ health independently, since sex influences experiences during military service (including exposure to health hazards) and after release.^{4 5} Females account for approximately 14% of 630 000 veterans currently residing in Canada,⁶ and 15.9% of Regular Force and Primary Reserve members of the Canadian Armed Forces.⁷ Female representation in the military is increasing in Canada and elsewhere^7–9 and the role of females in combat-related activities has expanded over time,⁸ supporting the need for research to understand their health and well-being. While some areas of veteran sex and gender research have broadened in recent years,⁴ Canadian information is scarce.¹⁰

The current study was conducted to examine and compare various negative health indicators of recent-era male and female veterans compared with their Canadian counterparts. This was done using a large and ongoing programme of research designed to better understand veteran health and wellness in Canada.

Methods

The scope of the current cross-sectional analysis is the health domain of Veterans Affairs Canada’s Well-being Surveillance Framework.¹¹ Variables were selected from a standard set of population health indicators available for both veterans (in the 2016 Life After Service Studies (LASS) Survey) and the Canadian general population (in the 2015–16 CCHS).¹²

Life After Service Studies (LASS) Survey

The LASS programme of research was designed to investigate the transition from military to civilian life and ultimately improve the health of veterans in Canada.¹³ Four cycles of data collection, in 2010, 2013, 2016 and 2019, have been conducted to date.

The 2016 LASS collected data on veterans who released from the Regular Force between 1998 and 2015. Veterans were identified from a computer-generated listing of Canadian military releases. Entry ranks (includes Recruit, Officer Cadet, Second Lieutenant) were excluded from the LASS 2016 to incorporate design changes that included new content. Also excluded were out-of-scope records for those with a residence in the three Northern Territories (due to small numbers) or re-enrolled in the Canadian Armed Forces, as well as those residing outside of Canada, living in an institution, or deceased (for consistency with CCHS eligibility criteria).

Statistics Canada collected survey data using the Computer Assisted Telephone Interview in February and March 2016. The 2016 LASS target sample of 4121 individuals was representative (after weighting) of the 56 419 Regular Force veterans released between 1998 and 2015 at postentry ranks (Officers, Senior Non-Commissioned Members and Junior Non-Commissioned Members). The survey had a 73% response rate (n=2999), with 92% of respondents agreeing to share their data with Veterans Affairs Canada and the Department of National Defence (n=2755).

Additional details on the LASS survey and methodology, including indicator definitions used, are documented elsewhere.^14–16

Canadian Community Health Survey (CCHS)

The CCHS is a national cross-sectional survey that collects information related to health status, healthcare utilisation and health determinants for the Canadian population.¹⁷ The survey, offered in both official languages, relies on a large sample of respondents and is designed to provide reliable health region level estimates every 2 years in Canada’s 10 provinces and 3 territories. Exclusions from the CCHS sampling frame, including full-time members of the Canadian Forces and individuals based on their geographical or institutionalisation status, represent <3% of the Canadian population aged 12 years and over.

Most comparator data for the general Canadian population were obtained from the CCHS 2015–16. CCHS 2015–16 data collection was carried out between January 2015 and December 2016, using computer-assisted in-person and telephone interviewing. Out of a total target sample of 185 176 individuals in scope for the survey, a response rate of 59.5% (110 095) was obtained. Health indicators of interest that were not available in the CCHS 2015–16 version were obtained from prior CCHS versions.

Further details of the CCHS survey measures, methodology and quality control methods are reported elsewhere.^{17 18}

Analyses

Comparisons between veterans and the Canadian general population were conducted using observed veteran distributions from the LASS and age-adjusted Canadian comparator data from the CCHS. Prevalence estimates incorporated survey sampling weights that accounted for both non-response and the complex stratified sampling designs of the LASS and the CCHS. Confidence Intervals (CIs were calculated at the 95% level with the Stata SVY command using a Taylor series linearisation. Population estimates based on sample sizes less than 30 were suppressed for data quality, according to Statistics Canada guidelines.¹⁶ Analyses focused on all chronic disease variables assessed in the LASS 2016, with the exceptions of ‘urinary incontinence’ and ‘Alzheimer’s disease or other dementia’, due to small response frequencies for both males and females. It also included variables addressing self-rated health, self-rated mental health, suicidal ideation and need for assistance with activities of daily living.

Results

Population, sex and age characteristics for the sample of 2755 Regular Force veterans who released between 1998 and 2015, as well as their Canadian counterparts, are described in Table 1. Both male and female veterans in the LASS sample were younger than the Canadian general population on average, with females representing 12.4% of veteran sample vs 54% of the general Canadian sample. Veterans were more likely than the general population to have a high school education and male veterans were more likely to be married or in a common law relationship compared with the Canadian general population (Table 2).

Negative health indicators in veterans and Canadians

Back problems and chronic pain were the most widely reported diagnosed chronic conditions in both male and female veterans (Table 3). Compared with their Canadian counterparts, male and female veterans reported a higher prevalence of fair or poor health and mental health, needing help with one or more activity of daily living, lifetime suicidal ideation and being diagnosed with mood and anxiety disorders, post-traumatic stress disorder, migraines, back problems, chronic pain, arthritis, ever having cancer, hearing problems, chronic pain and gastrointestinal problems. Cardiovascular disease (including heart disease, effects of stroke and/or high blood pressure (BP)) and high BP alone were more prevalent in male veterans compared with their Canadian counterparts. No differences were observed between male or female veterans and the general population for asthma, chronic obstructive pulmonary disease or diabetes.

Within-veteran comparisons

Within veterans only, males were more likely than females to report diagnosed hearing problems and cardiovascular disease. Female veterans were more likely than males to report diagnosed mood and anxiety disorders, migraines and gastrointestinal disorders, as well as needing help with one or more activity of daily living. These differences across sex are similar to those noted in the Canadian general population.

Some similarities between male and female veterans were not observed between sexes in the Canadian general population. Female non-veterans reported a higher prevalence than their male counterparts of: fair or poor mental health, lifetime suicidal ideation, arthritis, asthma, lifetime cancer incidence and chronic pain, all of which were reported equally in female versus male veterans. Male non-veterans reported a higher prevalence than females of diabetes; again, these outcomes were equally reported in male versus female veterans.

Discussion

This study examined various health indicators in male and female veterans compared with their counterparts in the Canadian general population. Both groups of veterans fared less well than other Canadians for many, though not all, health outcomes assessed. Similarities noted between male and female veterans may reflect the common conditions experienced by both sexes during military service, while differences may be due to the influence of sex and gender on the military experience.^{4 5}

The validity of our findings is generally supported by prior research over time and place, as described herein. A similar prevalence of fair or poor health has been reported by veterans in Australia (approximately 20% overall)¹⁹ and in the UK (with 25% of veterans reporting ‘fair’, ‘bad’ or ‘very bad’ health compared to 23% of non-veterans).²⁰ In a recent nationally representative US-based study, male veterans were more (female veterans equally) likely to report fair or poor self-rated health compared to their civilian counterparts (20.8% vs 13.8% for males²¹ and 17.9% vs 17.5% for females²²).

Functional limitations in both veterans and non-veterans have also been examined. In the UK in 2017, health problems were reported to limit activity ‘a lot’ for 26% and ‘a little’ for 35% of veterans versus for 24% and 31% of non-veterans.²⁰ In Australian veterans aged 55+ years, mild up to severe limitations have been observed in over 30% of individuals not receiving Department of Veterans’ Affairs payments and approximately two-thirds of those who do.¹⁹ A 2000 US Census-based study observed that both male and female veterans fared worse than non-veterans with respect to ‘any limitation or disability’, reported by 30% of female veterans (vs 24% of non-veterans) and 30% of male veterans (vs 22% of non-veterans).⁵ These veteran figures are similar to those reported in our study.

Recent national US estimates also indicate that veterans (65.3% of males and 70.1% of females) are more likely to report pain compared with non-veterans (51.8% of males and 60% of females).²³ This greater prevalence in veterans is consistent with our results, and may reflect veterans’ higher rates of back problems and arthritis compared with the Canadian general population. Musculoskeletal disorders, particularly low back issues, are a common cause of chronic pain and long-term physical disability,^{24 25} and have been identified as a primary reason for military medical discharge, for example, as demonstrated in regular members of the UK Armed Forces.²⁶ Also in agreement with our findings, US veterans have a greater likelihood of reporting back/neck problems and arthritis compared with non-veterans.²⁷

Hearing impairments in veterans, including hearing loss and tinnitus, are well documented across countries.^28–30 A significantly higher prevalence of severe hearing impairment has been observed in both male (10.9%) and female (4.0%) US veterans compared with non-veteran males (2.3%) and females (2.5%).^{21 22} A similar prevalence of hearing difficulties has been observed in male UK veterans (11% vs 7% of non-veterans) but not in females (4% vs 6% of non-veterans).²⁰ These veteran prevalence estimates are similar to those reported in the current study, wherein both male and female veterans reported a higher prevalence of hearing problems relative to their Canadian counterparts. Furthermore, a threefold greater prevalence was noted in male compared with female veterans in our study, a difference that has also been observed in UK and US veterans.^{20 30}

The lower prevalence of reported lifetime cancer incidence of veterans in the current study relative to other countries may relate to the relative youth of this population (including only individuals released from service since 1998). In line with our findings, US veterans have reported a higher prevalence of lifetime cancer diagnoses relative to their civilian counterparts (17.8% vs 5.5% for males; 14.1% vs 10.7% for females).^{21 22} In Australia, Vietnam war veterans have reported a 13.4% lifetime prevalence of cancer diagnosis (elevated compared with age-matched males in that country’s general population)²⁹ and higher rates of some cancers have also been noted in Korean war veterans.¹⁹ A study of Scottish veterans did not detect differences in overall cancer diagnoses in veterans compared with non-veterans, however increased risks of certain cancers (such as ovarian and breast cancers in females, and bladder and pancreatic cancers in males) were observed.³¹

A recent systematic review noted that reported rates of PTSD in general active duty and veteran populations varied from 11% to 14%, with rates in injured service members ranging from 30.3% to 79%.³² Few systematic reviews have reported on prevalence rates of mental health issues other than PTSD (eg, depression, anxiety or other disorders) or physical health in veteran populations, nor on comparisons with rates in civilian populations.³³ Our mental health results are consistent with prior (2010 and 2013) LASS survey cycles (also focused on veterans released from the Canadian Armed Forces since 1998), wherein poor self-rated mental health, mood disorders, anxiety disorders and PTSD was more prevalent compared with the general population.³⁴ Rates of mental disorders in serving personnel have also been noted as similar to or greater than those of general populations in Canada³⁵ and in Australia, with higher rates noted in recently discharged personnel versus actively serving members.¹⁹ A higher prevalence of poor mental health has been observed in deployed US male veterans and both deployed and non-deployed female veterans, compared with US civilians.³⁶

Sex is a known factor in suicidal behaviour, with ideation being significantly more prevalent among females than males globally (although males are more likely to die by suicide).^{37 38} Our finding of greater prevalence of suicidal ideation in both male and female veterans is also in line with prior Canadian research that has observed increased rates of suicide among these two groups compared with the general Canadian population, with highest rates among males.³⁹

Strengths and limitations

An important strength of this study is its sex-stratified approach to compare health outcomes in veterans with non-veteran Canadians. Although sex-based and gender-based analyses are widely recognised as an essential means to detect differences and provide insights for research and policy,⁴⁰ this approach is not consistently undertaken in studies of military and veteran populations. The small number of female respondents in the current study (n=341) is reflected in the relatively wide confidence intervals for some conditions assessed. This underscores the need for targeted studies with larger numbers of females and greater power to examine health effects in potentially important subgroups to inform further research and policy decisions.

The comparability of results between veterans and other Canadians is strengthened by the LASS 2015–16 questions being based on those used in the CCHS. However, this study’s reliance on self-reported data confers potential for reporting bias, which is difficult to estimate across the two surveyed populations. During service, Regular Forces personnel have regular access to a wide range of healthcare and rehabilitation services provided by the Canadian Armed Forces,⁴¹ which may have impacted some differences in self-reported diagnosed chronic conditions between veterans and other Canadians. Healthcare seeking behaviours also differ across males and females generally,⁴² which could have impacted the prevalence of self-reported diagnosed conditions by sex (and provides additional support for sex-stratified analyses).

Veterans surveyed in this study are generally representative of the Canadian veteran population released from military service between 1998 and 2015, with full record linkage to Department of National Defence administrative data and a strong survey response rate of 73%. Our findings cannot however be generalised to the full Canadian veteran population, since LASS 2016 included only Regular Force veterans who released between 1998 and 2015 and were above entry ranks at release. Furthermore, this sample was relatively young, with only 6% aged 65 years or older, and did not fully represent the eldest portion of the veteran population (age adjustment being unable to account for cohort and period effects). However, many of our results are comparable to earlier health comparisons between the full veteran population and other Canadians.¹ Although veterans are not identified in the 2015–16 CCHS and could therefore not be excluded, they represent fewer than 3% of those surveyed, and differences between veterans and the Canadian general population would be underestimated rather than overestimated.

While this paper focuses on describing negative indicators of health across veterans and Canadians, summaries of indicators for other well-being domains captured by the LASS 2016 are available elsewhere.^{14 43} Inter-relations between various health indicators assessed in this study, as well as other well-being domains, merit further study. For example, employment status (eg, disability and unemployment) has been associated with veteran health,⁴⁴ and commonly co-occurring chronic physical and mental health concerns have been observed to produce joint effects on work ability.^{45 46}

This study’s cross-sectional design does not permit an examination of health indicators over time, nor does it account for time since release from service. The longitudinal component of LASS may be leveraged in future analyses to examine how the transition from military to civilian life changes over time with respect to general health and well-being, chronic conditions, labour force participation and other factors.

Conclusion

The complexity of occupational and social factors encountered during and after military service identifies veterans as a subpopulation of Canadians who might require additional support. This is underscored by findings from the current study, which observed that both male and female veterans fared less well than the Canadian general population across a number of negative health indicators. These findings can be used to target future research to understand and improve the health of veterans in Canada and elsewhere. Research to examine the determinants of noted health disparities—including consideration of military service characteristics, sex and other social, employment and identity factors—is particularly warranted.
