Abstract
ObjectiveTo understand the prevalence of Chlamydia trachomatis (CT) infection and its associated factors among asymptomatic outpatients attending sexually transmitted disease (STD)-related clinics in Shenzhen and provide evidence for development of future interventions.
MethodsFrom April 15 to May 16, 2018, a cross-sectional study was conducted and patients attending STD-related Clinics were recruited from 22 medical institutions in Nanshan, Luohu, Bao'an, Longgang, Yantian, and Longhua districts of Shenzhen. After the informed consent from each participant was obtained, social-demographic information was collected through a structured questionnaire and urine samples were collected for CT nucleic acid detection. In addition, logistic regression was used to explore associated factors of CT infection.
ResultsIn asymptomatic outpatients, the prevalence of CT infection was 7.16% (250/3 492). Being single (aOR=2.29, 95%CI:1.65-3.16), without registered Shenzhen residency (aOR=1.49, 95%CI:1.04-2.13), and without previous CT testing in the past year (aOR=2.04, 95%CI:1.03-4.05) were the risk factors of CT infection in asymptomatic outpatients. Among participants without registered Shenzhen residency, 89.25% (2 176/2 438) were college-degree or below, and 51.29% (1 255/2 447) were aged ≤30 years, and the risk of CT infection among those ≤30 years old was 1.73 times higher than those >30 years old (95%CI:1.28-2.34).
ConclusionsThe prevalence of CT infection was high among asymptomatic outpatients attending STD-related clinics in Shenzhen. Routine CT screening should be carried out for this population, especially for those with sexually active age, being single, with low educational level, and without previous CT testing in the past year. Also, raising their awareness of knowledge and adverse outcomes of CT infection should be considered to promote routine CT screening and timely treatment.
