Longitudinal Health Study of US 1991 Gulf War Veterans: Changes in
Health Status at 10-Year Follow-up.
Li B, Mahan CM, Kang HK, Eisen SA, Engel CC.
Abstract
The authors assessed changes in the health status of US 1991 Gulf
War-era veterans from a 1995 baseline survey to a 2005 follow-up
survey, using repeated measurement data from 5,469 deployed Gulf War
veterans and 3,353 nondeployed Gulf War-era veterans who participated
in both surveys. Prevalence differences in health status between the 2
surveys were estimated for adverse health indices and chronic diseases
for each veteran group. Persistence risk ratios and incidence risk
ratios were calculated after adjustment for demographic and military
service characteristics through Mantel-Haenszel stratified analysis.
At 10-year follow-up, deployed veterans were more likely to report
persistent poor health, as measured by the health indices (functional
impairment, limitation of activities, repeated clinic visits,
recurrent hospitalizations, perception of health as fair or poor,
chronic fatigue syndrome-like illness, and posttraumatic stress
disorder), than nondeployed veterans. Additionally, deployed veterans
were more likely to experience new onset of adverse health (as
measured by the indices) and certain chronic diseases than were
nondeployed veterans. During the 10-year period from 1995 to 2005, the
health of deployed veterans worsened in comparison with nondeployed
veterans because of a higher rate of new onset of various health
outcomes and greater persistence of previously reported adverse health
on the indices.
