Title Publication Date/Location
Prior Assault and Posttraumatic Stress Disorder After Combat Deployment Epidemiology 2008 May;19(3):505-12

Smith TC, Wingard DL, Ryan MAK, Kritz-Silverstein D, Slymen DJ, Sallis JF, for the Millennium Cohort Study Team

In contrast to hypotheses that survival from trauma represents or confers resilience, these findings suggest vulnerability to combat stress and PTSD among survivors of prior assault.

Postcards Encourage Participant Updates Epidemiology 2009 Mar;20(2):313-4

Welch KE, LeardMann CA, Jacobson IG, Speigle SJ, Smith B, Smith TC, Ryan MAK, for the Millennium Cohort Study Team

The results of this study quantify and confirm that semiannual appreciatory contact is an effective way to maintain communication with a highly mobile participant population while prompting updates of contact information.

Prior Health Care Utilization as a Determinant to Enrollment in a 21-Year Prospective Study, the Millennium Cohort Study European Journal of Epidemiology 2008 Feb;23(2):79-87

Wells TS, Jacobson IG, Smith TC, Spooner CN, Smith B, Reed RJ, Amoroso PJ, Ryan MAK, for the Millennium Cohort Study Team

Few health differences between Millennium Cohort responders and non-responders were found when comparing healthcare utilization in the 12 months preceding study invitation.

Pre-incentive Efficacy in Survey Response Rates in a Large Prospective Military Cohort Field Methods 2023 Mar 17; 35(4), 392-408 | doi: 10.1177/1525822X231163668

Powell TM, Geronimo-Hara TR, Tobin LE, Donoho CJ, Sheppard BD, Walstrom JL, Rull RP, Faix DJ

U.S. military and veteran populations are challenging to retain in longitudinal studies as they span the globe, frequently move, and are heavily surveyed. This study tested the effectiveness of multiple pre-incentives ($2 bill, $5 gift card, magnet, and Apple iPad® lottery entry) on increasing the response rate to the 2014 survey of the Millennium Cohort Study. Findings suggest that providing participants a monetary pre-incentive was an effective way to increase response rates and participant retention as well as re-engage participants who did not respond to a previous follow-up survey.

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 Frontiers in Neurology 2023 Mar 21; 14:1110717 | doi: 10.3389/fneur.20

Belding JN, Kolaja CA, Rull RP, Trone DW for the Millennium Cohort Study Team

This study examined whether single and repeated high-level blast exposure (e.g., from incoming munitions) and low-level blast exposure (e.g., from outgoing munitions) were associated with 45 different self-reported diagnoses of illness and injury. Outcomes examined included PTSD, depression, hearing loss, tinnitus, chronic fatigue syndrome, and migraines. Findings suggest that blast exposure elevated risks for more than 20 different diagnoses and that repeated exposure was associated with worse outcomes.

Headache Disorders in the Millennium Cohort: Epidemiology and Relations with Combat Deployment Headache 2011 Jul-Aug;51(7);1098-1111

Jankosky C, Hooper TI, Granado NS, Scher A, Gackstetter GD, Boyko EJ, Smith TC, for the Millennium Cohort Study Team

Deployed personnel with reported combat exposure appear to represent a higher risk group for new-onset headache disorders. The identification of populations at higher risk for development of headache provides support for targeted interventions.

Smoking Among U.S. Service Members Following Transition From Military to Veteran Status Health Promotion Practice 2020 Jan;21(1_suppl):165S-175S

Nieh C, Powell TM, Gackstetter GD, Hooper TI

This study examined whether the time period just prior to military separation or the reasons for separation were associated with smoking among veterans. We found that service members are more likely to smoke when closer to their military separation date. The smoking prevalence among service members separating within 3 months was 23%, whereas 17% was observed among those separating in 2+ years. We also found that veterans who were heavy drinkers were 50% more likely to smoke and those with a standards/judicial-related separation reason were 69% more likely to smoke.

Smallpox Vaccination: Comparison of Self-Reported and Electronic Vaccine Records in the Millennium Cohort Study Human Vaccines 2007 Nov/Dec;3(6):245-51

LeardMann CA, Smith B, Smith TC, Wells TS, Ryan MAK, for the Millennium Cohort Study Team

Self-report of smallpox vaccination is very reliable. Results may be valuable in supporting global response to bioterrorism threats.

Self-Reported Adverse Health Events Following Smallpox Vaccination in a Large Prospective Study of US Military Service Members Human Vaccines 2008 Mar/Apr;4(2):127-33

Wells TS, LeardMann CA, Smith TC, Smith B, Jacobson IG, Reed RJ, Ryan MAK, for the Millennium Cohort Study Team

Smallpox vaccination was not associated with any adverse self-reported health outcomes, including mental and physical functioning. These findings may be reassuring to health care providers and those who receive the smallpox vaccination.

Newly Reported Hypertension After Military Combat Deployment in a Large Population-Based Study Hypertension 2009 Nov;54(5):966-73

Granado NS, Smith TC, Swanson GM, Harris RB, Shahar E, Smith B, Boyko EJ, Wells TS, Ryan MAK, for the Millennium Cohort Study Team

Findings suggest that deployers who report multiple combat exposures, especially those who personally witnessed a death due to war or disaster, are at higher risk for newly-reported hypertension, possibly indicating a stress-induced hypertensive effect.
