Urinary tract infections (UTIs) rank among the most common infections encountered in health care, with an annual incidence of 12% for women. Despite the vast numbers of international travels (over 1.5 billion annually), no prospective studies have had primary focus on UTIs during travel.
We recruited in 2008-17 international travelers who all filled out pre- and post-travel questionnaires. Incidence rates of UTI were calculated separately for both sexes. Multivariable analyses were conducted to identify risk factors for UTI during travel.
In total 15/517 (2,9%) travelers acquired UTI during travel, yielding an annual incidence of 62% for female and 18% for male travelers. Travelers' diarrhea (TD) was identified as a factor predisposing to UTI (OR 9.2, 95% CI 1.5-+∞, p = 0.011); all UTI cases were recorded by travelers with TD.
To our knowledge, this is the first prospective study with a primary focus on UTI during travel. Our data reveal that among travelers the incidence of UTI far exceeds that reported for the general population. TD was identified as a major risk factor for the infection. Our results suggest TD prevention as a means of also preventing UTI during travel.
尿路感染 (UTI) 是医疗保健中最常见的感染之一，女性的年发病率为 12%。尽管国际旅行人数众多（每年超过 15 亿人），但尚无前瞻性研究将重点放在旅行期间的 UTI 上。
我们于 2008 年至 2017 年招募了所有填写旅行前和旅行后问卷的国际旅行者。分别计算了男女旅行者 UTI 的发病率。进行了多变量分析以确定旅行期间 UTI 的危险因素。
共有 15/517（2.9%）名旅行者在旅行期间发生 UTI，女性旅行者的年发病率为 62%，男性旅行者的年发病率为 18%。旅行者腹泻（TD）被确定为 UTI 的易患因素（OR 9.2，95%CI 1.5-+∞，p=0.011）；所有 UTI 病例均由患有 TD 的旅行者记录。
据我们所知，这是第一项主要关注旅行期间 UTI 的前瞻性研究。我们的数据显示，在旅行者中，UTI 的发病率远远超过一般人群的报告。TD 被确定为感染的主要危险因素。我们的研究结果表明，TD 预防也是预防旅行期间 UTI 的一种手段。
