Knowledge on Chlamydia trachomatis and Acceptance to Testing for It Among Young Students in China

Abstract

Background 

Actively screening for Chlamydia trachomatis (CT) is important for young people because of a high prevalence of asymptomatic infection in this population. This study aimed to investigate knowledge on CT and preference to the screening services for CT among young students in China.

Methods 

From June to July 2022, a web-based questionnaire survey was conducted to collect information on sociodemographic characteristics, sexual behaviors, knowledge of CT, previous testing for CT, and preference to platform of testing for CT among Chinese young students. An online home-based self-sampling test (HBSST) service was offered free of charge if the participant was willing to be tested for CT. Statistical analyses included descriptive analysis, χ² test, and multivariable logistic regression.

Results 

Of 520 participants, 419 (80.6%) were aged between 16 and 24 years, 235 (45.2%) reported having sexual experience in the past, and 27 (5.2%) being tested before for CT. Slightly higher than 10% (57/520) of students were knowledgeable about CT. About one-third (36.9%) expressed their willingness to have a testing for CT but majority of them (63.1%) preferred to a free testing. Having sexual experience was significantly associated with the willingness to take the HBSST service (adjusted odds ratio, 2.96; 95% confidence interval, 1.92–4.58). A total of 139 (26.7%) participants requested the HBSST service online and 43.2% (60/139) returned the specimen for testing, in which 2 positives (3.3%) were found.

Conclusions 

The knowledge on CT and the previous uptake or current willingness to have a testing for CT was low among Chinese young students.

In Brief

A web-based survey found that Chinese young students were not well aware of chlamydia, and the students who had sexual experience were likely to accept a home-based chlamydia screening.
