Changes in Meeting Physical Activity Guidelines After Discharge from the Military | Journal of Physical Activity Health | 2015 May;12(5):666-674 |
Littman AJ, Jacobson IG, Boyko EJ, Smith TC Using data from Millennium Cohort Study participants, we investigated changes in meeting federal Physical Activity Guidelines for moderate-to-vigorous activity (MVPA) following military discharge. MVPA declined more in those who were discharged than those who were not (-17.8 percentage points vs. -2.7 percentage points), with greater declines in former active-duty personnel, those who had deployed with combat exposures, had 14-25 years of service, and had been discharged more recently (<1 year prior). Reductions in MVPA were substantial and unexpected. Increased understanding of transitional periods that may benefit from interventions to mitigate declines in physical activity will help prevent excess weight gain and physical inactivity-associated health consequences. |

Self-Reported Mental Health Among US Military Personnel, Prior and Subsequent to the Terrorist Attacks of September 11, 2001 | Journal of Occupational and Environmental Medicine | 2004 Aug;46(8):775-82 |
Smith TC, Smith B, Corbeil TE, Riddle JR, and Ryan MAK, for the Millennium Cohort Study Team Accepted without revision and featured by journal editors, this early analysis leveraged Millennium Cohort data to conclude that military members displayed stronger mental health characteristics soon after the terrorist attacks of September 11, 2001. The authors suggest this may be attributed to resilience and/or an outpouring of support for the US military mission. |

Impact of Terrorism on Caffeine and Tobacco Use | Journal of Occupational and Environmental Medicine | 2004 Dec;46(12):1194-5 |
Smith TC, Smith B, Corbeil TE, Ryan MAK, Riddle JR, for the Millennium Cohort Study Team [letter in response to "Self-reported mental health among US military personnel, prior and subsequent to the terrorist attacks of September 11, 2001"] Authors of a previously highlighted article respond to important suggestions on future analyses. |

Health Status of Gulf War and Era Veterans Serving in the US Military in 2000 | Journal of Occupational and Environmental Medicine | 2018 May;60(5):e261-e267 |
Porter B, Long K, Rull RP, Dursa EK for the Millennium Cohort Study Team This paper describes Gulf War Veterans and non-deployed Gulf era personnel enrolled in the Millennium Cohort Study. Comparing distributions of survey responses with those from a population-based sample collected by the VA, we found that Millennium Cohort participants reported slightly better health, particularly regarding mental health. The Millennium Cohort Study is an important resource for investigating the health effects of Gulf War deployment. |

The US Department of Defense Millennium Cohort Study: Career Span and Beyond Longitudinal Follow-Up | Journal of Occupational and Environmental Medicine | 2009 Oct;51(10):1193-1201 |
Smith TS, for the Millennium Cohort Study Team Describes the Millennium Cohort Study, a large longitudinal occupational health study designed and initiated prior to the combat deployments in Iraq and Afghanistan specifically to assess any short or long-term health outcomes during and after military service and career. |

Prevalence of Chronic Multisymptom Illness/Gulf War Illness Over Time Among Millennium Cohort Participants, 2001 to 2016 | Journal of Occupational and Environmental Medicine | 2020 Jan;62(1):4-10 |
Porter B, Long K, Rull RP, Dursa EK for the Millennium Cohort Study Team Chronic multisymptom illness/Gulf War illness (CMI/GWI) is a signature illness of the 1990-1991 Gulf War. Using a modified CMI/GWI definition, this study estimated the prevalence of CMI/GWI from 2001-2016 among Gulf War veterans and two other non-deployed groups enrolled in the Millennium Cohort Study. Overall, Gulf War veterans had the highest prevalence of CMI/GWI across the study period. The prevalence among all three groups increased substantially at approximately the same rate from 2001 to 2016. |

Individual Augmentee Deployment and Newly Reported Mental Health Morbidity | Journal of Occupational and Environmental Medicine | 2012 May;54(5):615-620 |
Granado NS, Zimmermann L, Smith B, Jones KA, Wells TS, Ryan MAK, Slymen DL, Koffman RL, Smith TC, for the Millennium Cohort Study Team Individual augmentees (IAs), who presumably have lower social support or unit cohesion, were not at increased risk for PTSD or mental health symptoms following deployment compared with non-IA deployers. It is likely that social isolation was not highly influential among Navy IAs in this study. |

The Effects of Exposure to Documented Open-Air Burn Pits on Respiratory Health Among Deployers of the Millennium Cohort Study | Journal of Occupational and Environmental Medicine | 2012 June;54(6):708-716 |
Smith B, Wong CA, Boyko EJ, Phillips CJ, Gackstetter GD, Ryan MAK, Smith TC, for the Millennium Cohort Study Team Burn pit exposure within 3 or 5 miles was not associated with newly reported asthma, chronic bronchitis or emphysema, or self-reported respiratory symptoms. In general, these findings do not support an elevated risk for respiratory outcomes among personnel deployed within proximity of documented burn pits in Iraq. Increased symptom reporting, however, was observed among Air Force deployers located within 2 miles of Joint Base Balad, though this finding was marginally significant with no evidence of trend. |

Newly Reported Lupus and Rheumatoid Arthritis in Relation to Deployment Within Proximity to a Documented Open-Air Burn Pit in Iraq | Journal of Occupational and Environmental Medicine | 2012 June;54(6):698-707 |
Jones KA, Smith B, Granado NS, Boyko EJ, Gackstetter GD, Ryan MAK, Phillips CJ, Smith TC, for the Millennium Cohort Study Team This study examined the incidence lupus and rheumatoid arthritis in relation to Army and Air Force personnel deployed within a 3- and 5-mile radius of documented open-air burn pits located in Iraq at Joint Base Balad, Camp Speicher, and Camp Taji. Overall, the results indicate no elevated risk of newly reported lupus or rheumatoid arthritis in the combined three-camp analysis. However, possible exposure at Balad was individually associated with newly reported lupus, although only two cases were at this site. Additional studies, including individual exposure data, are needed to further investigate these associations. |

Prospective Assessment of Chronic Multisymptom Illness Reporting Possibly Associated with Open-Air Burn Pit Smoke Exposure in Iraq | Journal of Occupational and Environmental Medicine | 2012 June;54(6):682-688 |
Powell TM, Smith TC, Jacobson IG, Boyko EJ, Hooper TI, Gackstetter GD, Phillips CJ, Smith B, for the Millennium Cohort Study Team There was no increase in chronic multisymptom illness (CMI) symptom reporting in Army and Air Force personnel deployed within a 2-, 3-, or 5-mile radius of documented open-air burn pits located in Iraq at Joint Base Balad, Camp Taji, and Camp Speicher compared with other deployed personnel. This initial report on possible burn pit exposure associated with CMI at apopulation-level is reassuring, but future research evaluating the potential association of burn pit smoke and CMI should utilize individual exposure data when possible. |
