Health and Health Behavior Differences

BACKGROUND Little is known about health and health behavior differences among military service veterans, active duty service members, National Guard/Reserve members, and civilians. Several important differences were identified among U.S. women from these subpopulations; to identify areas for targeted intervention, studies comparing men from these subpopulations are needed. PURPOSE To compare veteran, military, and civilian men on leading U.S. health indicators. METHODS Data were from the 2010 Behavioral Risk Factor Surveillance Survey, a U.S. population-based study. In 2011, self-reported health outcomes were compared using multivariable logistic regression across male veterans (n=53,406); active duty service members (n=2144); National Guard/Reserve service members (n=3724); and civilians (n=110,116). RESULTS Multivariate logistic regression results are presented. Despite better healthcare access, veterans had poorer health and functioning than civilians and National Guard/Reserve members on several indicators. Veterans also were more likely than those on active duty to report diabetes. Veterans were more likely to report current smoking and heavy alcohol consumption than National Guard/Reserve members and civilian men, and lack of exercise compared to active duty men and National Guard/Reserve members. National Guard/Reserve men had higher levels of obesity, diabetes, and cardiovascular disease (versus active duty and veterans, active duty, and civilians, respectively). Active duty men were more likely to report current smoking and heavy alcohol consumption than civilians and National Guard/Reserve members, and reported more smokeless tobacco use than civilians. CONCLUSIONS Veterans have poorer health and health behaviors; increased prevention efforts are needed from veteran-serving organizations. Despite good health, active duty men reported unhealthy lifestyles, indicating an important area for prevention efforts.

Health Indicators for Military, Veteran, and Civilian Women

BACKGROUND Women who have served in the military are a rapidly growing population. No previous studies have compared directly their health status to that of civilians. PURPOSE To provide estimates of several leading U.S. health indicators by military service status among women. METHODS Data were obtained from the 2010 Behavioral Risk Factor Surveillance Survey, a U.S. population-based study. Health outcomes were compared by military status using multivariable logistic regression among the female participants (274,399 civilians, 4221 veterans, 661 active duty, and 995 National Guard or Reserves [NG/R]). Data were analyzed in August 2011. RESULTS Veterans reported poorer general health and greater incidence of health risk behaviors, mental health conditions, and chronic health conditions than civilian women. Active duty women reported better access to health care, better physical health, less engagement in health risk behaviors, and greater likelihood of having had a recent Pap than civilian women. Women from the NG/R were comparable to civilians across most health domains, although they had a greater likelihood of being overweight or obese and reporting a depressive and anxiety disorder. CONCLUSIONS Compared with civilian women, NG/R women rated their health and access to health care similarly and active duty women rated theirs better on several domains, but veterans consistently reported poorer health.

Hopelessness and suicidal ideation in Iraq and Afghanistan war veterans reporting subthreshold and threshold posttraumatic stress disorder

We examined hopelessness and suicidal ideation in association with subthreshold and threshold posttraumatic stress disorder (PTSD) in a sample of Iraq and Afghanistan War Veterans (U.S., N = 275) assessed within a specialty VA postdeployment health clinic. Veterans completed paper-and-pencil questionnaires at intake. The military version of the PTSD Checklist was used to determine PTSD levels (No PTSD; subthreshold PTSD; PTSD), and endorsement of hopelessness or suicidal ideation were used as markers of elevated suicide risk. Veterans were also asked if they received mental health treatment in the prior 6 months. Veterans reporting subthreshold PTSD were 3 times more likely to endorse these markers of elevated suicide risk relative to the Veterans without PTSD. We found no significant differences in likelihood of endorsing hopelessness or suicidal ideation comparing subthreshold and threshold PTSD groups, although the subthreshold PTSD group was less likely to report prior mental health treatment. Clinicians should be attentive to suicide risk in returned Veterans reporting both subthreshold and threshold PTSD.

Modeling PTSD Symptom Clusters, Alcohol Misuse, Anger, and Depression as They Relate to Aggression and Suicidality in Returning U.S. Veterans

Suicidal ideation and aggression are common correlates of posttraumatic stress disorder (PTSD) among U.S. Iraq and Afghanistan war veterans. The existing literature has established a strong link between these factors, but a more nuanced understanding of how PTSD influences them is needed. The current study examined the direct and indirect relationships between PTSD symptom clusters and suicidal ideation in general aggression (without a specified target) regarding depression, alcohol misuse, and trait anger. Participants were 359 (92% male) U.S. Iraq/Afghanistan war veterans. Path analysis results suggested that the PTSD numbing cluster was directly (β = .28, p < .01) and indirectly (β = .17, p = .001) related through depression. The PTSD hyperarousal cluster was indirectly related to suicidal ideation through depression (β = .13, p < .001). The PTSD reexperiencing cluster was directly related to aggression (β = .17, p < .05), whereas the PTSD numbing and hyperarousal clusters were indirectly related to aggression through trait anger (β = .05, p < .05; β = .20, p < .001). These findings indicate that adjunct treatments aimed at stabilizing anger, depression, and alcohol misuse may help clinicians ameliorate the maladaptive patterns often observed in veterans. These results also point to specific manifestations of PTSD and co-occurring conditions that may inform clinicians in their attempts to identify at risk veterans and facilitate preventative interventions.

Association of Perceived Barriers With Prospective Use of VA Mental Health Care Among Iraq and Afghanistan Veterans

OBJECTIVE The relationship between perceived barriers and prospective use of mental health care among veterans was examined. METHODS The sample included Iraq and Afghanistan veterans (N=305) who endorsed symptoms of depression or posttraumatic stress disorder (PTSD) or alcohol misuse at intake to a postdeployment clinic between May 2005 and August 2009. Data on receipt of adequate treatment (nine or more mental health visits in the year after intake) were obtained from a VA database. RESULTS Adequate treatment was more likely for women (odds ratio [OR]=4.82, 95% confidence interval (CI)=1.37-16.99, p=.014) and for those with more severe symptoms of PTSD (OR=1.03, CI=1.01-1.05, p=.003) and depression (OR=1.06, CI=1.01-1.11, p=.01). Perceived barriers were not associated with adequate treatment. CONCLUSIONS Male veterans with mental health problems should be targeted with outreach to reduce unmet need. Research is needed to identify perceived barriers to treatment among veterans.

Post-Traumatic Stress Disorder, Physical Activity, and Eating Behaviors

Post-traumatic stress disorder (PTSD), a prevalent and costly psychiatric disorder, is associated with high rates of obesity and cardiometabolic diseases. Many studies have examined PTSD and risky behaviors (e.g., smoking, alcohol/substance abuse); far fewer have examined the relationship between PTSD and health-promoting behaviors. Physical activity and eating behaviors are 2 lifestyle factors that impact cardiometabolic risk and long-term health. This comprehensive review of the literature (1980-2014) examined studies that reported physical activity and eating behaviors in adults with PTSD or PTSD symptoms. A systematic search of electronic databases identified 15 articles on PTSD-physical activity and 10 articles on PTSD-eating behaviors in adults. These studies suggest that there may be a negative association among PTSD, physical activity, and eating behaviors. Preliminary evidence from 3 pilot intervention studies suggests that changes in physical activity or diet may have beneficial effects on PTSD symptoms. There was considerable heterogeneity in the study designs and sample populations, and many of the studies had methodological and reporting limitations. More evidence in representative samples, using multivariable analytical techniques, is needed to identify a definitive relationship between PTSD and these health behaviors. Intervention studies for PTSD that examine secondary effects on physical activity/eating behaviors, as well as interventions to change physical activity/eating behaviors that examine change in PTSD, are also of interest.

National evaluation of obesity screening and treatment among veterans with and without mental health disorders

OBJECTIVE The objective was to determine whether obesity screening and weight management program participation and outcomes are equitable for individuals with serious mental illness (SMI) and depressive disorder (DD) compared to those without SMI/DD in Veterans Health Administration (VHA), the largest integrated US health system, which requires obesity screening and offers weight management to all in need. METHODS We used chart-reviewed, clinical and administrative VHA data from fiscal years 2010-2012 to estimate obesity screening and participation in the VHAs weight management program (MOVE!) across groups. Six- and 12-month weight changes in MOVE! participants were estimated using linear mixed models adjusted for confounders. RESULTS Compared to individuals without SMI/DD, individuals with SMI or DD were less frequently screened for obesity (94%-94.7% vs. 95.7%) but had greater participation in MOVE! (10.1%-10.4% vs. 7.4%). MOVE! participants with SMI or DD lost approximately 1 lb less at 6 months. At 12 months, average weight loss for individuals with SMI or neither SMI/DD was comparable (-3.5 and -3.3 lb, respectively), but individuals with DD lost less weight (mean=-2.7 lb). CONCLUSIONS Disparities in obesity screening and treatment outcomes across mental health diagnosis groups were modest. However, participation in MOVE! was low for every group, which limits population impact.

Relationships Among Veteran Status, Gender, and Key Health Indicators in a National Young Adult Sample

OBJECTIVE Although many risk behaviors peak during young adulthood, little is known about health risk factors and access to care. This study assessed health indicators and health care access in a national sample of young adult veterans and civilians. METHODS Data were from the 2010 Behavioral Risk Factor Surveillance System, a national telephone survey. Of 27,471 participants, ages 19-30 years, 2.2% were veterans (74.6% were male) and 97.7% were civilians (37.6% were male). Gender-stratified comparisons assessed health indicators and health care access by veteran status. Multivariate logistic regression was used to examine health indicators and health care access as a function of gender and veteran status. RESULTS In the overall sample, women were more likely than men to have insurance, to have a regular physician, and to have had a routine checkup and yet were more likely to report financial barriers to care. Women also were more likely than men to report general medical and mental distress and higher lifetime anxiety and depressive disorders, whereas men were more likely to be overweight or obese and to report tobacco use and high-risk drinking. Adjusted analyses revealed a higher likelihood of general medical distress and higher rates of lifetime anxiety disorders among veterans compared with civilians, although there were no differences between veterans and civilians regarding health care utilization and hazardous drinking. CONCLUSIONS Findings extend the literature on health care status and modifiable risk factors for young adults by identifying differences between men and women and between veterans and civilians. Interventions may need to be tailored on the bases of gender and veteran status because of several differences in mental health and general health needs.

PTSD and depression symptoms are associated with binge eating among US Iraq and Afghanistan veterans

OBJECTIVE US Iraq and Afghanistan Veterans with post-traumatic stress disorder (PTSD) and depression are at increased risk for obesity. Understanding the contribution of health behaviors to this relationship will enhance efforts to prevent and reduce obesity. Therefore, we examined the association of PTSD and depression symptoms with binge eating, a risk factor for obesity, among Iraq/Afghanistan Veterans. METHOD Iraq/Afghanistan Veterans were assessed at intake to the VA Puget Sound Healthcare System-Seattle post-deployment clinic (May 2004-January 2007). The Patient Health Questionnaire was used to measure depression and binge eating symptoms, and the PTSD Checklist-Military Version assessed PTSD symptoms. RESULTS The majority of the sample (N=332) was male (91.5%) and Caucasian (72.6%), with an average age of 31.1 (SD=8.5) years; 16.3% met depression screening criteria, 37.8% met PTSD screening criteria, and 8.4% met binge eating screening criteria. In adjusted models, those meeting depression (odds ratio (OR)=7.53; 95% CI=2.69, 21.04; p<.001) and PTSD (OR=3.37; 95% CI=1.34, 8.46; p=.01) screening criteria were more likely to meet binge eating screening criteria. Continuous measures of PTSD and depression symptom severity were also associated with meeting binge eating screening criteria (ps<.05). CONCLUSION PTSD and depression are common conditions among Iraq/Afghanistan Veterans. In the present study, PTSD and depression symptoms were associated with meeting binge eating screening criteria, identifying a possible pathway by which psychiatric conditions lead to disproportionate burden of overweight and obesity in this Veteran cohort. Tailored dietary behavior interventions may be needed for Iraq/Afghanistan Veterans with co-morbid obesity and psychiatric conditions.

Readiness for Change Predicts VA Mental Healthcare Utilization Among Iraq and Afghanistan War Veterans

Many veterans present to Veteran Affairs (VA) care intending to seek mental health treatment for symptoms of posttraumatic stress disorder (PTSD), depression, and/or alcohol misuse, yet most subsequently underutilize mental health care. This study examined the association of readiness for change with outpatient VA mental health care utilization in 104 treatment-seeking Iraq and Afghanistan war veterans who screened positive for PTSD, depression, and/or alcohol misuse at intake. Multivariate analyses demonstrated that readiness for change assessed at intake was positively associated (Incident Rate Ratio [IRR] = 1.22) with prospective outpatient mental health care utilization with demographic factors, military characteristics, and mental health burden in the model. Results suggest that interventions that target readiness to change, such as motivational interviewing, may improve treatment utilization in veterans presenting for mental health care.
