The main objective of the Millennium Cohort Study is to provide evidence-based knowledge to inform and improve interventions,
clinical practice guidelines, and policies of key stakeholders, including Department of Defense (DoD) and Veteran’s Administration (VA)
leadership.
Since the launch of the cohort in 2001, the Millennium Cohort Study has investigated the impact of military service, including
deployments and other occupational exposures, on long-term mental, physical, and behavioral health of service members and veterans.
Along with our publications, we also fulfill requests for research that will be used to aid in policy decisions. For example, our team
recently provided results and findings describing the impacts of sexual harassment and sexual assault on service members to the Office
of Personnel and Readiness, Health Services Policy and Oversight. We have also conducted analyses examining adverse mental health
outcomes among Army veterinarians and veterinary technicians, as requested by the Commanding Officer of the Walter Reed Army
Institute of Research.
The unique strength of the Millennium Cohort Study is our ability to measure long-term health outcomes over a wide range of
exposures. We hope study results will help define healthcare policies, guide prevention and treatment programs, and strengthen
opportunities for future generations of military personnel. Examples of findings from the Millennium Cohort Study that have been used to
inform policy include:
Women’s Health
Substance Use
The 2020 National Defense Authorization Act (NDAA) directed the
Millennium Cohort Study to provide annual reports to Congress on
gynecological and perinatal health through 2022.
The Institute of Medicine (IOM) issued a report in 2013
entitled “Substance Use Disorders in the U.S. Armed
Forces” that included direct mention of the Millennium
Cohort Study and the unique capability to examine
substance use in service members and military families.
Respiratory Health
Health Promotion/Disease Prevention
In 2020, the National Academies Press published a consensus report
on respiratory health outcomes among service members who were
deployed to the Persian Gulf region and Afghanistan. Specific focus
of the analysis was on health outcomes of exposure to airborne
hazards associated with service in these regions. In particular, the study
evaluated and summarized “emerging evidence on respiratory health
outcomes in service members from research such as the Millennium
Cohort Study.”1 The report summarized findings across multiple studies
and recommendations for future research and policies as related to
respiratory health.
The Millennium Cohort Study is considered a
population health resource for informing performance
and readiness optimization of active-duty personnel.
Data from the study on obesity and deployability
have been used to inform current body composition
standards. Specific policy changes have been made
in DoD recruitment and retention policies. In addition,
information has been used to inform Veteran’s
Health Administration (VHA) weight management
programming.

Why is Sleep Research Important?
Sleep is essential for good health. Not getting enough uninterrupted sleep negatively affects a person’s attention, learning and memory,
and physical health.
• Sleep deficiency (too short or too long of sleep) and untreated sleep disorders are associated with a growing number of
health problems, including heart disease, high blood pressure, diabetes, obesity, and depression, all of which can be harmful
to military readiness.
• In addition to health problems, poor sleep is associated with lost worker productivity, and poor sleep and fatigue can cause
accidents, making sleep a serious public health issue.2
• Sleeping 7-9 hours per night is essential for optimal performance of the service member.
Key Points: What did the Millennium Cohort Study Find?
The Millennium Cohort Study is collaborating with leading sleep researchers to conduct research to understand how sleep affects health
over time and influences readiness and warfighter performance. Some example studies are featured below in Figure 1.

Summary: A 2013 study from the
Millennium Cohort Team showed
that combat-related trauma and
pre-deployment insomnia symptoms
were significantly associated with
developing post-traumatic stress
disorder, depression, and anxiety
following deployment at 3-year
follow-up.3
Summary: A 2016 study from
our research team showed that
insomnia impairs military readiness.
Participants with insomnia symptoms
were significantly more likely to have
worse self-rated health, more lost
workdays, lower odds of deployment,
higher odds of leaving military
service early, and more health care
utilization, compared to participants
without insomnia symptoms.4

Why is Research on Tobacco Use Important?
Tobacco use, through its many forms (cigarettes, vaping, cigars, smokeless tobacco), has many negative health effects and is related
to diseases such as cancer, heart disease, and chronic obstructive pulmonary disease (COPD). Tobacco use is the leading cause of
preventable death in the world.5
• Cigarettes and smokeless tobacco products are more often used among service members than the U.S. population.
• Regular tobacco use leads to diminished force readiness, medical morbidity (chronic conditions) and mortality (early death),
and increased spending for medical costs.
• According to the Military Health System, “using tobacco in any form poses a threat to readiness and the overall health
of the force.”6
• It is thought that smoking is used as a coping strategy for the stress experienced in military deployments.
Key Points: What did the Millennium Cohort Study Find?
The Millennium Cohort Study is collaborating with leading tobacco researchers to conduct research to understand how military service
and deployment affect tobacco use trends, mental and physical health in relation to tobacco use, and tobacco cessation. Some example
studies are featured below in Figure 2. We are currently collecting data related to vape use and will be reporting on this in the future.

Racial, Ethnic, and Sex Disparities in Mental Health Among U.S. Service Members and Veterans
Mental health experiences vary among people of different backgrounds. This study explored whether similar differences exist
within the U.S. military, focusing on how factors like race, ethnicity, and gender might influence the mental health of service
members and veterans. This paper is available online ahead of print at the American Journal of Epidemiology.
Individual and Military Factors That Modify the Association Between Recent Sexual Trauma and Health
Outcomes Among U.S. Service Members and Veterans
Experiences like sexual harassment and assault can take a toll on both your mind and body, affecting people in military and
civilian life alike. This study looked at whether personal experiences and military service influence how sexual trauma impacts
health, including anxiety, depression, physical pain, and sleep problems. This paper was published in the September 2023 issue of
Journal of Interpersonal Violence.
Lifetime Traumatic Brain Injury and Risk of Post-Concussive Symptoms
Many service members have experienced traumatic brain injuries (TBIs). This study looked at whether having more TBIs makes
symptoms like headaches, memory problems, and trouble sleeping (called post-concussive symptoms) more likely. This paper
was published in the June 26, 2023 issue of Journal of Neurotrauma.
Single and Repeated High-Level Blast, Low-Level Blast, and New-Onset Self-Reported Health Conditions in the
U.S. Millennium Cohort Study: An Exploratory Investigation
Service members exposed to blasts may experience various health issues. This study investigated whether service members who
experienced powerful blasts (from incoming fire) or smaller ones (from their own artillery) were more likely to report health
problems such as anxiety, depression, hearing loss, ringing in the ears, tiredness, and severe headaches. This paper was published
in the March 21, 2023 issue of Frontiers in Neurology.
Identifying At-Risk Marines: A Person-Centered Approach to Adverse Childhood Experiences, Mental Health,
and Social Support
While past studies have linked tough childhood experiences (like abuse or neglect) with health problems later in life, they often
examined each type of experience separately. This study took a different approach by looking at how unique combinations
of these experiences might affect people differently, giving us a clearer understanding of these connections. This project was
published in the March 15, 2023 issue of Journal of Affective Disorders.
Contribution of Post-Trauma Insomnia to Depression and Posttraumatic Stress Disorder in Women Service
Members
This project examined whether women service members and veterans who experienced recent combat and/or sexual
trauma were more likely to struggle with sleep problems (insomnia) compared with women who did not report these recent
experiences, and whether insomnia was linked with anxiety, depression, or other mental health issues. This paper was published
in the March 9, 2023 issue of Sleep.

Risk and Protective Factors for Cancer Mortality Among United States Service Members and Veterans
(2001-2018)
This study examined factors, including health behaviors and military experiences, that could affect the risk of dying from cancer
and focused on those who served in the wars in Iraq and Afghanistan. This paper was published in the May 1, 2023 issue of Cancer
Epidemiology, Biomarkers & Prevention.
The Bi-Directional Relationship Between Post-Traumatic Stress Disorder and Obstructive Sleep Apnea and/or
Insomnia in a Large U.S. Military Cohort
This study explored whether sleep problems like sleep apnea and insomnia could both cause and be caused by PTSD in service
members and veterans, and whether experiences such as combat deployment could affect these relationships. This project was
published in the December 2022 issue of Sleep Health.

Dear ,
Mental health is vital to everyone’s overall health but is often overlooked or stigmatized. Millennium Cohort Study
research shows that mental health conditions like PTSD, depression, and anxiety can often coexist with other
problems like insomnia, substance abuse, or unhealthy weight, all of which can lower quality of life.
By completing your current Millennium Cohort Study survey, you will help us better understand the impact of
military service on the long-term mental health and quality of life of service members. To get started, simply visit
our website at:
Your Subject ID is:
A 2016 study using Millennium Cohort Study data found that service members with combat deployments
developed PTSD and other mental health disorders (anxiety, depression, etc.) more often than those with noncombat deployments or no deployments.
The research team is working to better understand and identify risk factors for these mental health conditions.
Through this investigation, the team can strengthen prevention measures and inform policies to promote mental
health care and education.
Our research team can only conduct this important work due to the continued involvement of our dedicated
participants.
Thank you for your time and consideration.
Sincerely,
The Millennium Cohort Study Team
