Sexually transmitted infections (STIs) present a continuing challenge to the efforts to prevent disease in the military. Since the degree of high-risk sexual behavior is a primary determinant for acquiring STIs, the identification of personality traits or situations associated with such behavior is of special interest.
Data for this study were obtained from the 1998 Department of Defense Survey of Health Related Behaviors Among Military Personnel. The survey instrument was a self-administered questionnaire that was conducted using a stratified, two-stage, two-phase probability design to obtain representative samples of U.S. active duty personnel worldwide.
More frequent episodes of alcohol intoxication were associated in a dose-dependent manner with an increased risk of having more sexual partners in the previous 12 months. Men and women who experienced intoxication more than 3 days per week were, respectively, 4.55 and 6.18 times more likely to have more than one sexual partner in the previous year.
This study is based on retrospective self-report and may be subject to recall bias as well as information bias due to the sensitive nature of the subject matter. However, the results are compatible with a personality-based hypothesis, in which individuals with certain sensation-seeking tendencies may incur an increased risk for sexually transmitted infections.
性传播感染（STIs）对军队疾病预防工作构成持续挑战。由于高危性行为的程度是感染性传播感染的主要决定因素，识别与此类行为相关的人格特质或情况具有特殊意义。
本研究的数据来自1998年国防部对军事人员健康相关行为的调查。调查工具是一份自填式问卷，采用分层、两阶段、两期概率设计进行，以获取全球美国现役人员的代表性样本。
在过去12个月中，更频繁的酒精中毒发作与拥有更多性伴侣的风险增加呈剂量依赖性相关。每周醉酒超过3天的男性和女性，在前一年有多个性伴侣的可能性分别是其他人的4.55倍和6.18倍。
本研究基于回顾性自我报告，由于主题的敏感性，可能存在回忆偏差和信息偏差。然而，研究结果与基于人格的假设相符，即具有某些寻求刺激倾向的个体感染性传播感染的风险可能会增加。
