| The Epidemiology of Irritable Bowel Syndrome in the US Military: Findings from the Millennium Cohort Study | American Journal of Gastroenterology | 2016;111:93-104 |
|
Riddle MS, Welsh M, Porter CK, Nieh C, Boyko EJ, Gackstetter GD, Hooper TI This study describes the incidence of irritable bowel syndrome (IBS) and its association with antecedent infectious gastroenteritis among Millennium Cohort Study participants using survey data and post-deployment health assessments and medical encounter data in the military health system. Consistent with other studies, the risk of IBS increased after acute enteric infection. Novel findings included increased risk of incident IBS among those with post-traumatic stress disorder (PTSD) and preceding life stressors, as well as stronger associations between infectious gastroenteritis and IBS among those with antecedent depression or anxiety. These results reinforce the need to prevent acute gastrointestinal infections and their chronic consequences among our Service members. Additional studies on the underlying biopsychosocial mechanisms of IBS may help to explain these findings. |

| Chronic Multisymptom Illness: A Comparison of Iraq and Afghanistan Deployers with 1991 Gulf War Veterans | American Journal of Epidemiology | 2014;180(12):1176-1187 |
|
Smith TC, Powell TM, Jacobson IG, Smith B, Hooper TI, Boyko EJ, Gackstetter GD These data highlight a difference in CMI reporting when comparing deployed to non-deployed military members. While symptom reporting in this contemporary Cohort occurred less frequently than in the historical 1991 GW cohort, increased CMI reporting was noted among deployed compared to non-deployed contemporary Cohort members. |

| Longitudinal Associations Among PTSD, Disordered Eating, and Weight Gain in Military Men and Women | American Journal of Epidemiology | 2016 Jul 1;184(1):33-47 |
|
Mitchell KS, Porter B, Boyko EJ, Field AE This study examined longitudinal associations between PTSD, disordered eating, and weight change in Millennium Cohort data from U.S. military Service members who completed the baseline survey and first and second follow-up surveys. The association between PTSD and weight change from time 2 to time 3 was partially mediated by disordered eating symptoms measured at time 2, specifically compensatory behaviors (vomiting, laxative use, fasting, over-exercise). In stratified models, the association between PTSD and weight gain via compensatory behaviors was significant for men and for non-Hispanic white participants only. Results highlight potentially important demographic differences in these associations and emphasize the need for further investigation of eating disorders in military Service members. |

| A Decade of War: Prospective Trajectories of Posttraumatic Stress Disorder Symptoms Among Deployed US Military Personnel and the Influence of Combat Exposure | American Journal of Epidemiology | 15 December 2017;186(12):1310–1318. |
|
Donoho CJ, Bonanno GA, Porter B, Kearney L, Powell TM Using survey data collected at four different time points over a 10-year study period, four distinct patterns of PTSD symptoms were observed among deployed personnel. More than 85% of participants were found to be resilient with almost no PTSD symptoms. Despite similarity in pre-deployment symptoms, those experiencing combat-related trauma had higher PTSD symptom levels following deployment across every trajectory compared with those not exposed to combat-related trauma. These findings suggest the clinical course of PTSD symptoms has a heterogeneous pattern of development, but that combat exposure is uniformly associated with poorer mental health. |

| New-Onset Asthma and Combat Deployment: Findings from the Millennium Cohort Study | American Journal of Epidemiology | 2018 Oct 1;187(10):2136-2144 |
|
Rivera AC, Powell TM, Boyko EJ, Lee RU, Faix DJ, Luxton DD, and Rull RP New-onset asthma developed in 2.7% of men and 4.6% of women during the follow-up period, among participants without a prior diagnosis of asthma at baseline. Compared with those who did not deploy, those who deployed with combat experience were 24-30% more likely to develop asthma, even after controlling for smoking status and other covariates. No elevated risk was observed for deployers who did not experience combat. Additional risk factors for asthma among both men and women included Hispanic ethnicity, overweight or obesity, Army service, stressful life events, PTSD, and health care or other technical occupations. |

|
Donoho CJ, Bonanno GA, Porter B, Kearney L, and Powell TM Details the reasons that the results found in "A decade of war: Prospective trajectories of post-traumatic stress disorder symptoms among deployed US military personnel and the influence of combat exposure" are not likely to be confounded by mefloquine side effects. |

|
Jacobson IG, Smith TC, Smith B, Keel PK, Amoroso PJ, Wells TS, Bathalon GP, Boyko EJ, Ryan MAK for the Millennium Cohort Study Team Deployed women who reported combat exposures represent a subgroup at higher risk for developing eating problems and weight loss postdeployment compared with deployed women who did not report combat exposures. |

|
Smith B, Wong CA, Smith TC, Boyko EJ, Gackstetter GD, Ryan MAK, for the Millennium Cohort Study Team Elevated risk for self-reported respiratory symptoms was found among Army and Marine Corps personnel deployed in support of operations in Iraq and Afghanistan. No increased risk for self-reported asthma, bronchitis, or emphysema was found. |
