With increasing international travel it is important to understand how frequent casual travel sex and unprotected intercourse are, and what impact this may have on the risk of acquiring sexually transmitted infections (STIs).
We conducted a systematic review, and where appropriate meta-analyses, to ascertain the influence of foreign travel on behavior, including new partnerships, unprotected intercourse, and STI acquisition.
The pooled prevalence of travel-associated casual sex was 20.4% (95% confidence interval (CI) 14.8-26.7%), with 49.4% (95% CI 38.4-60.5%) of these having unprotected intercourse. The predominant characteristics of people who had new sexual partners abroad were: young age, male gender, single status, and traveling alone or with friends, with a previous history of multiple sexual partners or an STI. People who travel or stay abroad for longer periods and men who have sex with men are at higher risk of developing new sexual partnerships and having unprotected intercourse. The risk of developing an STI is increased up to 3-fold in people who experience casual travel sex.
New sexual partnerships and unprotected intercourse abroad are relatively common. People who develop new sexual partnerships and have unprotected intercourse abroad have an increase risk of STIs. There is, however, a paucity of information related to strategies to prevent the risk of STI acquisition during foreign travel.
随着国际旅行的增加，了解偶然的旅行性行为和无保护性行为的频率以及这可能对性传播感染（STI）的风险有何影响变得非常重要。
我们进行了系统评价，并在适当的情况下进行了荟萃分析，以确定外国旅行对行为的影响，包括新的伴侣关系、无保护的性行为和 STI 的获得。
偶然旅行性行为的总体患病率为 20.4%（95%置信区间 [CI] 14.8-26.7%），其中 49.4%（95% CI 38.4-60.5%）没有采取保护措施。在国外有新性伴侣的人的主要特征是：年轻、男性、单身、独自或与朋友旅行，并有多个性伴侣或性传播感染的既往史。旅行或在国外逗留时间较长的人以及男男性行为者更容易发生新的性伴侣关系和无保护的性行为。有偶然旅行性行为的人患 STI 的风险增加了 2-3 倍。
在国外发生新的性伴侣关系和无保护性行为相对常见。在国外发展新的性伴侣关系和发生无保护性行为的人患性传播感染的风险增加。然而，关于在国外旅行期间预防性传播感染风险的策略，相关信息却很少。
