Sexually transmitted infections (STIs) are prevalent in the U.S. military. However, there are limited data on risk-factor differences between sexes.
We used data from the 2008 Department of Defense Survey of Health Related Behaviors among active duty military personnel to identify risk factors for self-reported STIs within the past 12 months and multiple sexual partners among sexually active unmarried service members.
There were 10,250 active duty personnel, mostly white (59.3%) aged 21 to 25 years (42.6%). The prevalence of any reported STI in the past 12 months was 4.2% for men and 6.9% for women. One-fourth of men and 9.3% of women reported 5 or more sexual partners in the past 12 months. Binge drinking, illicit substance use, and unwanted sexual contact were associated with increased report of sexual partners among both sexes. Family/personal-life stress and psychological distress influenced number of partnerships more strongly for women than for men (Adjusted Odds Ratio [AOR]=1.58, 95% Confidence Interval [CI]=1.18-2.12 and AOR=1.41, 95% CI=1.14-1.76, respectively). After adjusting for potential confounders, we found that the report of multiple sexual partners was significantly associated with the report of an STI among men (AOR, 5.87 [95% CI, 3.70-9.31], for ≥5 partners; AOR, 2.35 [95% CI, 1.59-3.49], for 2-4 partners) and women (AOR, 4.78 [95% CI, 2.12-10.80], for ≥5 partners; AOR, 2.35 [95% CI, 1.30-4.25], for 2-4 partners).
Factors associated with the report of increasing sexual partnerships and report of an STI differed by sex. Sex-specific intervention strategies may be most effective in mitigating the factors that influence risky sexual behaviors among military personnel.
性传播感染（STIs）在美国军队中很普遍。然而，关于两性之间风险因素差异的数据有限。
我们使用了2008年国防部现役军人健康相关行为调查的数据，以确定在过去12个月内自我报告的性传播感染以及性活跃的未婚军人中多个性伴侣的风险因素。
共有10250名现役人员，大多数为白人（59.3%），年龄在21至25岁之间（42.6%）。在过去12个月中，报告患有任何性传播感染的男性患病率为4.2%，女性为6.9%。四分之一的男性和9.3%的女性报告在过去12个月中有5个或更多性伴侣。酗酒、非法药物使用和非自愿性接触与两性中性伴侣报告增加有关。家庭/个人生活压力和心理困扰对女性性伴侣数量的影响比对男性更强（调整后的优势比[AOR]=1.58，95%置信区间[CI]=1.18 - 2.12；AOR=1.41，95% CI=1.14 - 1.76）。在调整潜在混杂因素后，我们发现男性中多个性伴侣的报告与性传播感染的报告显著相关（对于≥5个性伴侣，AOR为5.87 [95% CI，3.70 - 9.31]；对于2 - 4个性伴侣，AOR为2.35 [95% CI，1.59 - 3.49]），女性中也是如此（对于≥5个性伴侣，AOR为4.78 [95% CI，2.12 - 10.80]；对于2 - 4个性伴侣，AOR为2.35 [95% CI，1.30 - 4.25]）。
与性伴侣数量增加报告和性传播感染报告相关的因素因性别而异。针对性别的干预策略可能在减轻影响军人危险性行为的因素方面最有效。
