Prevalence of asymptomatic chlamydial infecton among students and development of preventive screening methods.

普通学生群体中无症状衣原体感染的流行病学研究尚未发现。之前的调查分析的数据来自可能存在偏见的样本，而不是一般的学生群体。为了描述学生中无症状衣原体感染的流行情况、危险因素和筛查方法，实施了基于人群的横断面调查。参与者包括10111名18岁以上的无症状学生志愿者。女性患病率为9.6%，男性为6.7%。作者描述了可靠的流行病学信息和筛查方法，以促进提高覆盖率和减少对一般学生群体的偏见。包括危险性行为在内的选择性标准将有助于对受感染个体进行有效筛查。

Asymptomatic chlamydial infection among general student populations has not yet been detected epidemiologically. Previous surveys have analyzed data from potentially biased samples, not general student populations. To describe prevalence, risk factors and screening methods for asymptomatic chlamydial infection among students, population-based cross-sectional surveys were implemented. Participants comprised 10,111 asymptomatic student volunteers【greater than or equal】18-years-old. Prevalence was 9.6% for females and 6.7% for males. The authors describe reliable epidemiological information and screening methods to facilitate improved coverage and reduce bias among general student populations. Selective criteria including risky sexual behaviors will allow efficient screening for infected individuals.
