Abstract

BACKGROUND

Sexually transmitted infections (STIs) are among the frequent risks encountered by travelers. Efficient interventions are needed to improve the understanding of the risks of STIs. We investigated the potential benefits of a motivational brief intervention (BI) and the provision of condoms on the engagement in unprotected casual sex.

METHODS

3-arm randomized controlled trial performed among single travelers aged 18-44 years visiting a travel clinic in Switzerland. The main outcomes were the prevalence of casual unprotected sexual intercourse and their predictors.

RESULTS

5148 eligible travelers were seen from 2006 to 2008. 1681 agreed to participate and 1115 subjects (66%) completed the study. 184/1115 (17%) had a casual sexual relationship abroad and overall 46/1115 (4.1%) had inconsistently protected sexual relations. Women (adjusted OR 2.7 [95%CI 1.4-5.6]) and travelers with a history of past STI (adjusted OR 2.8 [95%CI 1.1-7.4]) had more frequent casual sexual relationships without consistent protection. Regarding the effect of our intervention, the prevalence of subjects using condoms inconsistently was 28% (95%CI16-40) in the motivational BI group, 24% (95%CI10-37) in the condoms group and 24% (95%CI14-33) in the control group (p = 0.7).

CONCLUSION

This study showed that a motivational brief intervention and/or the provision of free condoms did not modify risky sexual behavior of young travelers. The rate of inconsistently protected sexual relationships during travel was however lower than expected

摘要

背景

性传播感染（STIs）是旅行者经常面临的风险之一。需要有效的干预措施来提高对 STIs 风险的认识。我们调查了动机性简短干预（BI）和提供避孕套对参与无保护偶然性行为的潜在益处。

方法

在瑞士一家旅行诊所对 18-44 岁的单身旅行者进行了 3 臂随机对照试验。主要结局是偶然无保护性行为的流行率及其预测因素。

结果

2006 年至 2008 年期间，有 5148 名符合条件的旅行者接受了检查。1681 人同意参与，1115 人（66%）完成了研究。1115 人中 184 人（17%）在国外有过偶然的性关系，总体上有 46 人（4.1%）有不一致的保护性行为。女性（调整后的 OR 2.7 [95%CI 1.4-5.6]）和有过去性传播感染史的旅行者（调整后的 OR 2.8 [95%CI 1.1-7.4]）更频繁地发生无保护的偶然性行为。关于我们干预的效果，在动机 BI 组，使用避孕套进行不一致保护的受试者比例为 28%（95%CI16-40），在避孕套组为 24%（95%CI10-37），在对照组为 24%（95%CI14-33）（p=0.7）。
