DASA, 2008 (Update)

Summary statistics of causes of death from April 1, 1991, to December 31, 2007

UK GWVs (n = 53,409) vs era veterans (n = 54,143)

Mortality due to diseases of the circulatory system

MRR 0.87 (95% CI 0.70-1.07)

Age

Roughly the same cohort as MacFarlane et al., 2005

Ishoy et al., 1999b (Update)

Cross-sectional

686 Danish peacekeepers deployed to gulf in 1990-1997 vs 231 age- and sex-matched armed forces nondeployed controls

Blood pressure measured by physician

Deployed vs nondeployed:

Systolic: 127 (sd = 12) vs 126 (sd = 11) mmHg

Diastolic: 78 (sd = 9) vs 76 (sd = 10) mmHg

 

Participation rate 83.6% deployed, 57.8% nondeployed

Sim et al., 2003 (Update)

Cross-sectional, mailed questionnaire and clinical examination

1371 male and 30 female Australian GWVs; 1368 male and 32 female NDVs

Blood pressure measured by a physician

High-normal blood pressure, males: OR 1.1 (95% CI 0.9-1.3) Hypertension, males: OR 1.1 (95% CI 0.9-1.4); females: similar prevalence (3%) in both groups

Service type, rank, age, education, marital status

High participation in deployed veterans (male 81%, female 79%), but low participation in control group (male 57%, female 44%) possibly leading to participation bias
