COVID-19 Incidence, Risk Factors, Impact, and Related Stigma Among a Cohort of Persons With HIV in Washington, DC.

BACKGROUND: Studies on the incidence of COVID-19 among persons with HIV (PWHs) present varied results. Few studies have investigated the impact of COVID-19 infection on health and socioeconomic factors or COVID-19 stigma. We sought to measure the incidence and severity of COVID-19 infection among a cohort of PWHs, characterize associated risk factors and impact, and document perceptions of COVID-19-related stigma. METHODS: Data for this cross-sectional study come from the COVID-19 survey of participants in the DC Cohort longitudinal study from October 30, 2020, through December 31, 2022. Survey results were linked to electronic health records, including HIV laboratory test results and COVID test results. We conducted analyses comparing demographic, socioeconomic, HIV measures, and stigma among those with and without self-reported COVID-19. RESULTS: Of 1972 survey respondents, 17% self-reported COVID-19 infection, with the greatest incidence in the Omicron wave of the pandemic. We found statistically significant differences by age, employment status, essential worker status, education, and household income. Longer duration of HIV diagnosis was associated with greater incidence of COVID-19. PWHs who were overweight or obese had a greater incidence of COVID-19 compared with those who were not. Over 40% of PWHs with COVID-19 reported experiencing at least 1 form of COVID-19-related stigma. CONCLUSION: We observed a high incidence of COVID-19 infection among PWHs in DC. Furthermore, a substantial proportion of PWHs with COVID-19 reported experiencing COVID-19-related stigma. These findings add to the existing literature on COVID-19 coinfection among PWHs and highlight the need for awareness and support for those experiencing COVID-19 stigma.

Mixed Methods Analysis of Telehealth Experience, Satisfaction, and Quality of Care During the COVID Pandemic Among Persons with HIV in Washington, DC.

The purpose of this study is to describe telehealth experiences and quality of HIV care provided to an urban population of people with HIV (PWH) in Washington, DC. We used self-reported survey data from a cohort of PWH in the DC Cohort longitudinal study linked to medical records (October 26, 2020-December 31, 2021). Analyses followed a mixed-methods approach, including prevalence estimates and multivariable logistic regression of telehealth use by demographic and HIV characteristics. We measured primary motivation, modes of engagement, and telehealth satisfaction. Qualitative responses to open-ended questions were coded using collaborative coding. A framework developed by the National Quality Forum (NQF) was applied to the results. Among 978 participants, 69% reported using telehealth for HIV care during the pandemic. High school graduates were less likely to use telehealth compared to those with college education (aOR 0.69, 95% CI 0.48, 0.98). PWH with > 1 co-morbid condition were more likely to use telehealth compared to those without (aOR 1.42, 95% CI 1.02, 1.95). The majority reported satisfaction with telehealth (81%). Qualitative analysis of telehealth satisfaction found that most responses were related to access to care and technology, effectiveness, and patient experience. PWH using telehealth during the pandemic were satisfied with their experience though use differed demographically. Telehealth was used effectively to overcome barriers to care engagement, including transportation, costs, and time. As we transition away from the emergency pandemic responses, it will be important to determine how this technology can be used in the future in an equitable manner to further strengthen HIV care engagement.

The impact of COVID-19 on the HIV continuum of care: challenges, innovations, and opportunities.

INTRODUCTION: In February 2019, the United States (US) launched the Ending the HIV Epidemic (EHE) initiative with emphasis on improving the various steps of the Human Immunodeficiency Virus (HIV) prevention and care continuum. However, in March 2020, the Coronavirus Disease 2019 (COVID-19) pandemic was declared, curtailing efforts to end the epidemic in the US. AREAS COVERED: To describe the impact of the pandemic on EHE in the US, the authors performed a comprehensive literature review focusing on outcomes at each step of the HIV care continuum. Simultaneously, they identified examples of pandemic-era innovations that may help EHE. EXPERT OPINION: Numerous studies demonstrated pandemic-related disruptions across the care continuum as well as the impact on preexisting barriers to care among People with HIV (PWH) at higher risk for poor outcomes. As the pandemic progressed, innovative approaches to delivering healthcare and providing essential services emerged, including widespread use of telemedicine, expansion of home-based care, self-collected sexually transmitted infection (STI) and HIV testing, and co-located testing for COVID-19 and HIV/STIs. While the COVID-19 pandemic initially hindered achieving EHE in the US, the ability to be agile, flexible, and creative led to innovation in HIV care delivery that may ultimately assist in meeting EHE goals as we transition into the post-pandemic era.

Psychosocial impacts of the COVID-19 pandemic from a cross-sectional Survey of people living with HIV in Washington, DC.

BACKGROUND: COVID-19 has not only taken a staggering toll in terms of cases and lives lost, but also in its psychosocial effects. We assessed the psychosocial impacts of the COVID-19 pandemic in a large cohort of people with HIV (PWH) in Washington DC and evaluated the association of various demographic and clinical characteristics with psychosocial impacts. METHODS: From October 2020 to December 2021, DC Cohort participants were invited to complete a survey capturing psychosocial outcomes influenced by the COVID-19 pandemic. Some demographic variables were also collected in the survey, and survey results were matched to additional demographic data and laboratory data from the DC Cohort database. Data analyses included descriptive statistics and multivariable logistic regression models to evaluate the association between demographic and clinical characteristics and psychosocial impacts, assessed individually and in overarching categories (financial/employment, mental health, decreased social connection, and substance use). RESULTS: Of 891 participants, the median age was 46 years old, 65% were male, and 76% were of non-Hispanic Black race/ethnicity. The most commonly reported psychosocial impact categories were mental health (78% of sample) and financial/employment (56% of sample). In our sample, older age was protective against all adverse psychosocial impacts. Additionally, those who were more educated reported fewer financial impacts but more mental health impacts, decreased social connection, and increased substance use. Males reported increased substance use compared with females. CONCLUSIONS: The COVID-19 pandemic has had substantial psychosocial impacts on PWH, and resiliency may have helped shield older adults from some of these effects. As the pandemic continues, measures to aid groups vulnerable to these psychosocial impacts are critical to help ensure continued success towards healthy living with HIV.

The association of pre-war medical conditions to Gulf War Illness.

AIMS: Gulf War Illness (GWI) remains a significant health concern for many veterans. The relation of pre-war health conditions and symptoms to GWI could aid in developing a more accurate case definition of GWI. The objective of this study was to investigate pre-war predictors of GWI in a population-based sample of Gulf War veterans using two definitions of GWI. MAIN METHODS: Data come from the 1995-1997 National Health Survey of Persian Gulf War Era Veterans, a survey of a representative sample of deployed and non-deployed US veterans. Using two definitions of GWI (CDC/Kansas and a newly developed 3-domain definition), we conducted a series of multivariable logistic regression analyses to assess the associations of demographic, lifestyle factors, and pre-war medical conditions and symptoms to subsequent GWI. KEY FINDINGS: All pre-war symptom predictor domains were significantly and positively associated with GWI using a new 3-domain definition with aORs for individual domains ranging from 2.17 (95% CI = 1.99-2.38) for dermatologic conditions to 3.06 (95% CI = 2.78-3.37) for neurological conditions. All symptom predictor domains were associated with significantly increased likelihood of GWI using the CDC/Kansas definition, with aORs ranging from 2.54 (95% CI = 2.31-2.81) for inflammatory conditions to 3.22 (95% CI = 2.94-3.55) for neurological conditions. These estimates were attenuated but remained significant after inclusion of all significant symptom predictor domains. SIGNIFICANCE: Results from this study suggest that demographic/lifestyle factors and pre-war medical conditions are strong predictors of GWI. Additional research is needed to confirm these findings, and to clarify the unique characteristics of this common, but still poorly understood illness.

Reevaluating Suicide Mortality for Veterans With Data From the VA-DoD Mortality Data Repository, 2000-2010.

OBJECTIVE: The Department of Veterans Affairs and Department of Defense Mortality Data Repository (MDR) compiles National Death Index records for all veterans and military service members. This study aimed to compare MDR findings with those from a preexisting data source. METHODS: Veteran suicide rates estimated from death certificates were replicated with the MDR. Annual suicide rates were computed for veterans overall, by gender, and by Veterans Health Administration service utilization and compared with rates for adult nonveterans by using standardized mortality ratios (SMRs). RESULTS: Suicide rates and SMRs differed between the data sources. The 2010 MDR-derived veteran suicide rate was 27.4 deaths per 100,000 veterans, compared with an earlier estimate of 35.9. Differences were greater for females. Divergence was attributed to improved accuracy identifying veteran suicide decedents in the MDR. CONCLUSIONS: Conditions with low base rates can be major public health problems, and minor misclassification can substantially affect surveillance accuracy, prevention efforts, and the validity of study findings.

A randomized controlled trial of public messaging to promote safe firearm storage among U.S. military veterans.

BACKGROUND: The objectives of this study were to determine whether short-term exposure to firearm safety messaging significantly improved (1) firearm storage practices, and (2) attitudes of safe firearm storage behaviors among U.S. veterans, a group at elevated risk for firearm suicide. DESIGN: A three-arm, parallel-group RCT was conducted online in the U.S. nationwide from December 2015 to January 2016. SETTING: A national random sample of U.S. veterans (N = 358) was recruited from the GfK KnowledgePanel, a probability-based internet panel representative of U.S. adults. All study activities were administered online over a three-week study period. INTERVENTION: Participants were randomized and exposed three times (once per week) to either (a) firearm safety message only (n = 115); (b) firearm safety and mental health promotion messages (n = 133); or (c) active control group exposed to mental health promotion message only (n = 110). Each message was less than two minutes long. MEASURES: Assessments were completed at baseline (pre-randomization) and at end-of-trial. Changes in awareness of risk for injuries, attitudes/beliefs related to safe storage practices, behavioral intentions, and storage practices were measured using self-reported surveys. Linear mixed effect models with weighted generalized estimating equations were used to test for exposure effects. Analyses were conducted February 2018. RESULTS: Analyses restricted to those with baseline firearm access (n = 195) identified no significant changes for intentions or safe storage practices across exposure groups. At baseline, participants' attitudes and beliefs were generally supportive of safe firearm storage. The Firearm Safety message yielded small increases in agreement with the concept that secure storage is "important during emotional or stressful times" (0.36; 95% CI = 0.08, 0.64). Other significant changes in awareness and beliefs were found, but across all study conditions. CONCLUSION: Results reinforce the critical need for considerable research and testing prior to the widespread implementation of public messages to increase the likelihood for desired exposure effects.

Health Status of Female and Male Gulf War and Gulf Era Veterans: A Population-Based Study.

BACKGROUND: The health of women Gulf War (deployed) and Gulf Era (nondeployed) veterans is understudied; although most studies examining the health effects of deployment to the Gulf War adjust for gender in multivariate analyses, gender-specific prevalence and effect measures are not routinely reported. The National Academy of Medicine recommended that the Department of Veterans Affairs assess gender-specific health conditions in large cohort studies of Gulf War veterans. METHODS: Data from this study come from the follow-up study of a national cohort of Gulf War and Gulf Era veterans. This study was conducted between 2012 and 2014, and was the second follow-up of a population-based cohort of Gulf War and Gulf Era veterans that began in 1995. Measures included self-reported medical conditions and frequency of doctor visits as well as validated screening instruments for mental health conditions. RESULTS: Overall, female veterans (both Gulf War and Era) reported poorer health than their male counterparts as measured by the prevalence of self-reported disease. The top five prevalent conditions in both Gulf War and Gulf Era veterans were migraine, hypertension, major depressive disorder, arthritis, and dermatitis. Female Gulf War veterans were found to have a higher prevalence of disease than male Gulf Era veterans. CONCLUSIONS: Women veterans, particularly deployed veterans, from this era have significant medical needs that may justify increased outreach from the Department of Veterans Affairs. Our findings highlight the importance of asking about military service, particularly for women veterans, in the clinical setting, both in the Department of Veterans Affairs and in the private sector.

Trends in brain cancer mortality among U.S. Gulf War veterans: 21 year follow-up.

OBJECTIVE: Previous mortality studies of U.S. Gulf War veterans through 2000 and 2004 have shown an increased risk of brain cancer mortality among some deployed individuals. When veterans possibly exposed to environmental contaminants associated with demolition of the Khamisiyah Ammunition Storage Facility at Khamisiyah, Iraq, have been compared to contemporaneously deployed unexposed veterans, the results have suggested increased risk for mortality from brain cancer among the exposed. Brain cancer mortality risk in this cohort has not been updated since 2004. METHODS: This study analyzes the risk for brain cancer mortality between 1991-2011 through two series of comparisons: U.S. Gulf War deployed and non-deployed veterans from the same era; and veterans possibly exposed to environmental contaminants at Khamisiyah compared to contemporaneously deployed but unexposed U.S. Gulf War veterans. Risk of brain cancer mortality was determined using logistic regression. Life test hazard models were created to plot comparisons of annual hazard rates. Joinpoint regression models were applied to assess trends in hazard rates for brain cancer mortality. RESULTS: U.S. Army veterans possibly exposed at Khamisiyah had similar rates of brain cancer mortality compared to those not possibly exposed; however, veterans possibly exposed had a higher risk of brain cancer in the time period immediately following the Gulf War. CONCLUSION: Results from these analyses suggest that veterans possibly exposed at Khamisiyah experienced different patterns of brain cancer mortality risk compared to the other groups.

Lifetime Prevalence of Respiratory Diseases and Exposures Among Veterans of Operation Enduring Freedom and Operation Iraqi Freedom Veterans: Results From the National Health Study for a New Generation of U.S. Veterans.

OBJECTIVE: The objective of this study was to determine the prevalence of respiratory exposures and the association between respiratory exposures and respiratory disease among veterans deployed to Operation Enduring Freedom and Operation Iraqi Freedom (OEF/OIF) compared with nondeployed veterans of this era. METHODS: Data come from a national health survey of 20,563 deployed and nondeployed OEF/OIF era veterans. Prevalence estimates and adjusted odds ratios were calculated. Results were weighted to represent the population. RESULTS: Prevalence of at least one respiratory exposure was high among both deployed and nondeployed groups (95% and 70%, respectively). In both groups, those with any respiratory exposure were at an increased risk for reporting a respiratory disease. CONCLUSION: Respiratory exposures are highly prevalent and are associated with increased odds of respiratory diseases among the OEF/OIF era population.

Cigarette Smoking and Sociodemographic, Military, and Health Characteristics of Operation Enduring Freedom and Operation Iraqi Freedom Veterans: 2009-2011 National Health Study for a New Generation of US Veterans.

OBJECTIVE: We examined the sociodemographic, military, and health characteristics of current cigarette smokers, former smokers, and nonsmokers among Operation Enduring Freedom (OEF) / Operation Iraqi Freedom (OIF) veterans and estimated smoking prevalence to better understand cigarette use in this population. METHODS: We analyzed data from the US Department of Veterans Affairs (VA) 2009-2011 National Health Study for a New Generation of US Veterans. On the basis of a stratified random sample of 60 000 OEF/OIF veterans, we sought responses to a 72-item questionnaire via mail, telephone, or Internet. Cigarette smoking status was based on self-reported cigarette use in the past year. We used multinomial logistic regression to evaluate associations between smoking status and sociodemographic, military, and health characteristics. RESULTS: Among 19 911 veterans who provided information on cigarette smoking, 5581 were current smokers (weighted percentage: 32.5%, 95% confidence interval [CI]: 31.7-33.2). Current smokers were more likely than nonsmokers or former smokers to be younger, to have less education or income, to be separated/divorced or never married/single, and to have served on active duty or in the army. Comparing current smokers and nonsmokers, some significant associations from adjusted analyses included the following: having a Mental Component Summary score (a measure of overall mental health) above the mean of the US population relative to below the mean (adjusted odds ratio [aOR] = 0.81, 95% CI: 0.73-0.90); having physician-diagnosed depression (aOR = 1.52, 95% CI: 1.33-1.74), respiratory conditions (aOR = 1.16, 95% CI: 1.04-1.30), or repeated seizures/blackouts/convulsions (aOR = 1.80, 95% CI: 1.22-2.67); heavy alcohol use vs never use (aOR = 5.49, 95% CI: 4.57-6.59); a poor vs excellent perception of overall health (aOR = 3.79, 95% CI: 2.60-5.52); and being deployed vs nondeployed (aOR = 0.87, 95% CI: 0.78-0.96). Using health care services from the VA protected against current smoking. CONCLUSION: Mental and physical health, substance use, and military service characteristics shape cigarette-smoking patterns in OEF/OIF veterans.

All-Cause Mortality Among US Veterans of the Persian Gulf War: 13-Year Follow-up.

OBJECTIVE: We determined cause-specific mortality prevalence and risks of Gulf War deployed and nondeployed veterans to determine if deployed veterans were at greater risk than nondeployed veterans for death overall or because of certain diseases or conditions up to 13 years after conflict subsided. METHODS: Follow-up began when the veteran left the Gulf War theater or May 1, 1991, and ended on the date of death or December 31, 2004. We studied 621   901 veterans who served in the 1990-1991 Persian Gulf War and 746   247 veterans who served but were not deployed during the Gulf War. We used Cox proportional hazard models to calculate rate ratios adjusted for age at entry to follow-up, length of follow-up, race, sex, branch of service, and military unit. We compared the mortality of (1) Gulf War veterans with non-Gulf War veterans and (2) Gulf War army veterans potentially exposed to nerve agents at Khamisiyah in March 1991 with those not exposed. We compared standardized mortality ratios of deployed and nondeployed Gulf War veterans with the US population. RESULTS: Male Gulf War veterans had a lower risk of mortality than male non-Gulf War veterans (adjusted rate ratio [aRR] = 0.97; 95% confidence interval [CI], 0.95-0.99), and female Gulf War veterans had a higher risk of mortality than female non-Gulf War veterans (aRR = 1.15; 95% CI, 1.03-1.28). Khamisiyah-exposed Gulf War army veterans had >3 times the risk of mortality from cirrhosis of the liver than nonexposed army Gulf War veterans (aRR = 3.73; 95% CI, 1.64-8.48). Compared with the US population, female Gulf War veterans had a 60% higher risk of suicide and male Gulf War veterans had a lower risk of suicide (standardized mortality ratio = 0.84; 95% CI, 0.80-0.88). CONCLUSION: The vital status and mortality risk of Gulf War and non-Gulf War veterans should continue to be investigated.

Demographic, Military, and Health Characteristics of VA Health Care Users and Nonusers Who Served in or During Operation Enduring Freedom or Operation Iraqi Freedom, 2009-2011.

An estimated 60% of all Operation Enduring Freedom / Operation Iraqi Freedom (OEF/OIF) veterans who have left the military had used the US Department of Veterans Affairs (VA) for health care services as of March 31, 2015. What is not known, however, are the differences in demographic, military, and health characteristics between OEF/OIF veterans who use the VA for health care and OEF/OIF veterans who do not. We used data from the 2009-2011 National Health Study for a New Generation of US Veterans to explore these differences. We found that VA health care users were more likely than non-VA health care users to be non-Hispanic black, to be unmarried, to have served on active duty and in the army, to have been deployed to OEF/OIF, and to have an annual income less than $35 000. The prevalence of 21 chronic medical conditions was higher among VA health care users than among non-VA health care users. OEF/OIF veterans using the VA for health care differ from nonusers with respect to demographic, military, and health characteristics. These data may be useful for developing programs and policies to address observed health disparities and achieve maximum benefit for the VA beneficiary population.

Physical and Mental Health Status of Gulf War and Gulf Era Veterans: Results From a Large Population-Based Epidemiological Study.

OBJECTIVE: The aim of the study was to report the mental and physical health of a population-based cohort of Gulf War and Gulf Era veterans 20 years after the war. METHODS: A multimode (mail, Web, or computer-assisted telephone interviewing) heath survey of 14,252 Gulf War and Gulf Era veterans. The survey consisted of questions about general, physical, mental, reproductive, and functional health. RESULTS: Gulf War veterans report a higher prevalence of almost all queried physical and mental health conditions. The population as a whole, however, has a significant burden of disease including high body mass index and multiple comorbid conditions. CONCLUSIONS: Gulf War veterans continue to report poorer heath than Gulf Era veterans, 20 years after the war. Chronic disease management and interventions to improve health and wellness among both Gulf War and Gulf Era veterans are necessary.

Military Sexual Trauma Among Recent Veterans: Correlates of Sexual Assault and Sexual Harassment.

INTRODUCTION: Military sexual trauma (MST) includes sexual harassment or sexual assault that occurs during military service and is of increasing public health concern. The population prevalence of MST among female and male veterans who served during Operations Enduring Freedom and Iraqi Freedom (OEF/OIF) has not been estimated to our knowledge. The purpose of this study is to assess the population prevalence and identify military correlates of MST, sexual harassment, and sexual assault among OEF/OIF veterans. METHODS: MST was assessed in the 2009-2011 National Health Study for a New Generation of U.S. Veterans, a survey of 60,000 veterans who served during the OEF/OIF eras (response rate, 34%, n=20,563). Weighted prevalence estimates and AORs of MST, sexual harassment, and sexual assault among women and men were calculated. Gender-stratified logistic regression models controlled for military and demographic characteristics. Data analyses were conducted in 2013-2014. RESULTS: Approximately 41% of women and 4% of men reported experiencing MST. Deployed men had lower risk for MST compared with non-deployed men, though no difference was found among women. However, veterans reporting combat exposure during deployment had increased risk for MST compared with those without, while controlling for OEF/OIF deployment. Among women, Marines and Navy veterans had increased risk for MST compared with Air Force veterans. MST was significantly higher among veterans who reported using Veterans Affairs healthcare services. CONCLUSIONS: These prevalence estimates underscore the importance of public awareness and continued investigation of the public health impact of MST.

CAM utilization among OEF/OIF veterans: findings from the National Health Study for a New Generation of US Veterans.

BACKGROUND: Complementary and alternative medicine (CAM) is increasingly seen as an adjunct to traditional plans of care. This study utilized a representative sample of Operation Enduring Freedom and Operation Iraqi Freedom (OEF/OIF) veterans and OEF/OIF-era veterans to explore the prevalence and characteristics of CAM users. RESEARCH DESIGN: The National Health Study for a New Generation of US Veterans (NewGen) is a longitudinal health study of a population-based cohort of OEF/OIF (deployed) and OEF/OIF-era (nondeployed) veterans. Data from the 2009-2011 NewGen survey (n=20,563) were analyzed to determine prevalence of CAM use by demographic and military characteristics, the types of CAM modalities used, and where the modalities were sought. Results were weighted to the entire population of OEF/OIF and OEF/OIF-era veterans. RESULTS: There was no statistically significant association between CAM use and deployment. Those who used Department of Veterans Affairs (VA) health care after separation were more likely to be CAM users compared with those who did not use VA care; however, the majority of veterans using CAM are using it outside the VA health care system. Massage was the most prevalent CAM modality followed by chiropractic treatment; males were less likely to use CAM than women. CONCLUSIONS: CAM modalities are being utilized by OEF/OIF veterans for health problems mainly outside the VA. Policymakers should determine appropriate use of these modalities.

Prevalence of a positive screen for PTSD among OEF/OIF and OEF/OIF-era veterans in a large population-based cohort.

Multiple studies have reported the prevalence of posttraumatic stress disorder (PTSD) in Operation Enduring Freedom and Operation Iraqi Freedom (OEF/OIF) veterans; however, these studies have been limited to populations who use the Department of Veterans Affairs (VA) for health care, specialty clinic populations, or veterans who deployed. The 3 aims of this study were to report weighted prevalence estimates of a positive screen for PTSD among OEF/OIF and nondeployed veterans, demographic subgroups, and VA health care system users and nonusers. The study analyzed data from the National Health Study for a New Generation of U.S. Veterans, a large population-based cohort of OEF/OIF and OEF/OIF-era veterans. The overall weighted prevalence of a positive screen for PTSD in the study population was 13.5%: 15.8% among OEF/OIF veterans and 10.9% in nondeployed veterans. Among OEF/OIF veterans, there was increased risk of a positive screen for PTSD among VA health care users (OR = 2.71), African Americans (OR = 1.61), those who served in the Army (OR = 2.67), and those on active duty (OR = 1.69). The same trend with decreased magnitude was observed in nondeployed veterans. PTSD is a significant public health problem in OEF/OIF-era veterans, and should not be considered an outcome solely related to deployment.

Prevalence of respiratory diseases among veterans of Operation Enduring Freedom and Operation Iraqi Freedom: results from the National Health Study for a New Generation of U.S. Veterans.

This study investigated the population prevalence of asthma, bronchitis, and sinusitis among veterans deployed to Afghanistan and Iraq compared to nondeployed veterans. A 2009-2011 population-based health survey of 60,000 veterans (34% response rate) asked about the history of doctor-diagnosed respiratory disease. Analyses included smoking history, deployment status, and year of diagnosis. The prevalence of asthma, bronchitis, and sinusitis among those diagnosed during or after 2001 was 3.3%, 5.9%, and 6.9%, respectively, among the deployed veterans and 3.4%, 5.3%, and 5.6%, respectively, among the nondeployed veterans. Deployed veterans were 29% more likely to have been diagnosed with sinusitis during and after 2001 compared to nondeployed veterans (adjusted odds ratio = 1.30, 95% confidence interval = 1.13, 1.49). Deployed veterans are at increased risk for sinusitis compared to nondeployed. There was no significant difference in asthma or bronchitis risk between deployed and nondeployed veterans.
