Objectives
Prevalence assessment is one of the core components of WHO-recommended STI surveillance programming. This study aimed to provide prevalence and associated factors data for estimating the disease burden of CT, developing intervention programmes, and planning for resource allocations.
Methods
We carried out a cross-sectional survey among patients attending clinics for STI services. We collected background information from patients (aged 18-49) and determined positivity of CT by nucleic acid amplification test (NAAT) with self-collected urine specimens. Associated factors identified through logistic regression.
Results
Among the 8324 participants, 751 were detected to be positive for CT, giving an overall prevalence of 9.0% with 10.7% for male and 8.3% for female respectively. Aged older than 24 (OR=0.78, 95%CI=0.62-0.98), married (OR=0.61, 95%CI=0.50-0.75), college or higher education (OR=0.66, 95%CI=0.51-0.86), having no access to health insurance (OR=1.28, 95%CI=1.07-1.51), and positive for NG (OR=4.45, 95%CI=3.22-6.15) were factors found to be significantly associated with CT infection.
Conclusions
We found that CT infection is prevalent among patients seeking clinic-based STI services in Shenzhen, China. A comprehensive CT screening, surveillance, and treatment programme targeting this population are warranted. And the CT integrated prevention and control projects could be considered as routine public health services by the government.
