Few data are available on the prevalence and risk factors for Chlamydia trachomatis infection among young men in Brazil.
To assess prevalence and risk factors for C. trachomatis infection in male military conscripts.
In 2000, 627 young men recruited for military service in Goiania, Goias, Brazil, were enrolled in this cross-sectional study. Participants completed a demographic and sexual risk behavior questionnaire, and urine samples were screened for C. trachomatis by polymerase chain reaction.
The prevalence of chlamydial infection among asymptomatic conscripts was 5.0% (95% confidence interval [CI], 3.3-7.3). In multivariate analysis, failure to use condoms (odds ratio OR 5.3; 95% confidence interval [CI], 1.2-23.4; P = 0.028) and having more than 2 sexual partners in the last 2 months (OR(adjusted) 2.6; 95% CI, 1.1-6.9; P = 0.049) were significantly associated with positivity for C. trachomatis.
A substantial number of asymptomatic young male military recruits were infected with C. trachomatis, and risk factors for this infection were related to sexual behavior. Further research is required to determine if routine screening may be considered as a strategy to reduce prevalence among this population.
关于巴西年轻男性沙眼衣原体感染的患病率及危险因素的数据很少。
评估男性应征入伍者沙眼衣原体感染的患病率及危险因素。
2000年，在巴西戈亚斯州戈亚尼亚市招募的627名年轻男性应征入伍者参与了这项横断面研究。参与者完成了一份人口统计学和性风险行为问卷，并通过聚合酶链反应对尿液样本进行沙眼衣原体筛查。
无症状应征入伍者中衣原体感染的患病率为5.0%（95%置信区间[CI]，3.3 - 7.3）。在多变量分析中，未使用避孕套（调整后的优势比[OR] 5.3；95%置信区间[CI]，1.2 - 23.4；P = 0.028）以及在过去2个月内有超过2个性伴侣（调整后的OR 2.6；95% CI，1.1 - 6.9；P = 0.049）与沙眼衣原体阳性显著相关。
大量无症状的年轻男性新兵感染了沙眼衣原体，这种感染的危险因素与性行为有关。需要进一步研究以确定是否可将常规筛查视为降低该人群患病率的一种策略。
