The prevalence of trichomoniasis in the general population of the United States is unknown. This study provides the first population-based prevalence estimates of trichomoniasis among young adults in the United States.
The National Longitudinal Study of Adolescent Health (Add Health) is an ongoing prospective cohort study. In a cross-sectional analysis of Wave III of Add Health (N = 12,449), we determined the prevalence of trichomoniasis using a polymerase chain reaction assay.
The estimated overall prevalence of trichomoniasis in U.S. young adults was 2.3% (95% confidence interval [CI], 1.8-2.7%). The prevalence was slightly higher among women (2.8%; 95% CI, 2.2-3.6%) than men (1.7%; 95% CI, 1.3-2.2%). The prevalence increased with age and varied by region, with the south having the highest prevalence (2.8%; 95% CI, 2.2-3.5%). The prevalence was highest among black women (10.5%; 95% CI, 8.3-13.3%) and lowest among white women (1.1%; 95% CI, 0.8-1.6%). Among men, the prevalence was highest among Native Americans (4.1%; 95% CI, 0.4-29.3%) and blacks (3.3%; 95% CI, 2.2-4.9%), and lowest among white men (1.3%; 95% CI, 0.9-1.8%).
Trichomoniasis is moderately prevalent among the general U.S. population of young adults and disturbingly high among certain racial/ethnic groups.
美国普通人群中滴虫病的患病率尚不清楚。本研究首次提供了美国年轻人群中滴虫病基于人群的患病率估计。
青少年健康全国纵向研究（Add Health）是一项正在进行的前瞻性队列研究。在对Add Health第三波（N = 12449）的横断面分析中，我们使用聚合酶链反应测定法确定滴虫病的患病率。
美国年轻成年人中滴虫病的估计总体患病率为2.3%（95%置信区间[CI]，1.8 - 2.7%）。女性患病率（2.8%；95%CI，2.2 - 3.6%）略高于男性（1.7%；95%CI，1.3 - 2.2%）。患病率随年龄增长而增加，且因地区而异，南部患病率最高（2.8%；95%CI，2.2 - 3.5%）。黑人女性患病率最高（10.5%；95%CI，8.3 - 13.3%），白人女性患病率最低（1.1%；95%CI，0.8 - 1.6%）。在男性中，美洲原住民患病率最高（4.1%；95%CI，0.4 - 29.3%），黑人次之（3.3%；95%CI，2.2 - 4.9%），白人男性患病率最低（1.3%；95%CI，0.9 - 1.8%）。
滴虫病在美国年轻成年人普通人群中患病率中等，但在某些种族/族裔群体中高得令人不安。
