This is the first longitudinal cohort study of Persian Gulf War US soldiers to examine belief in exposure to chemical and biological weapons before and shortly after combat. A longitudinal sample of n = 1250 male Persian Gulf War US Army soldiers were surveyed 3 to 4 months before and 6 to 10 months after the 1991 War. Six to 10 months after combat, 4.6% of the cohort believed they had been exposed to chemical and biological weapons. Adjusting for demographics only, those who reported a greater number of combat exposures (odds ratio, OR: 18.8), or higher combat stress (OR: 12.27) were more likely to believe they were exposed. Adjusting for all variables soldiers who reported higher combat stress continued to be most likely (OR: 6.58) to believe they had been exposed to chemical and biological weapons. Individuals reporting higher combat stress are at substantially greater risk of reporting they have been exposed to chemical or biological weapons.
这是对参加海湾战争的美国士兵进行的首次纵向队列研究，旨在调查他们在战斗前及战斗刚结束后对接触化学和生物武器的信念。对n = 1250名参加海湾战争的美国陆军男性士兵进行纵向抽样，在1991年海湾战争前3至4个月及战后6至10个月进行调查。战斗结束后6至10个月，该队列中有4.6%的人认为自己接触过化学和生物武器。仅对人口统计学因素进行调整后，报告有更多战斗经历（优势比，OR：18.8）或更高战斗压力（OR：12.27）的人更有可能认为自己接触过此类武器。对所有变量进行调整后，报告有更高战斗压力的士兵仍然最有可能（OR：6.58）认为自己接触过化学和生物武器。报告有更高战斗压力的个体报告自己接触过化学或生物武器的风险显著更高。
