Abstract
This study was aimed to estimate the prevalences of chlamydia (CT) and gonococcal (NG) infections and explore risk factors associated with the CT infection among women in Shenzhen, China. We collected socio-demographic and clinical data from women (aged 20–60) and determined positivity of CT or NG by nucleic acid amplification test (NAAT) with self-collected urine specimens. We estimated prevalence of CT and NG and determined risk factors associated with CT infection. Among 9,207 participants, 4.12% (95% confidence interval [CI], 3.71%-4.53%) tested positive for CT and 0.17% (95% CIs, 0.09%-0.25%) for NG. Factors significantly associated with CT infection included being an ethnic minority (ethnicity other than Han China) (Adjusted odds ratio [AOR], 1.9; 95% CI, 1.2–3.0), using methods other than condom for contraception (AOR, 1.5; 95% CI, 1.2–1.8), having a history of adverse pregnancy outcomes (AOR, 1.4; 95% CI, 1.1–1.8), and experiencing reproductive tract symptoms in the past three months (AOR, 1.3; 95% CI, 1.0–1.7). we found that CT infection is prevalent among women in Shenzhen, China and associated with both demographic and behavioral factors. A comprehensive CT screening, surveillance and treatment programme targeting this population is warranted.
Highlights
As major sexually transmitted infections (STIs), chlamydia caused by Chlamydia trachomatis (C. trachomatis, CT) and gonorrhoea caused by Neisseria gonorrhoeae (N. gonorrhoeae, NG) are important public health problems in many developed and developing countries [1,2,3]
A total of 9,207 (99.5%) participants who completed the questionnaire survey and provided urine specimens for successfully detecting CT and NG by polymerase chain reaction (PCR) were included for data analyses
All participants were Chinese nationals and the majority (97.0%) of participants were of Han ethnicity
Summary
As major sexually transmitted infections (STIs), chlamydia caused by Chlamydia trachomatis (C. trachomatis, CT) and gonorrhoea caused by Neisseria gonorrhoeae (N. gonorrhoeae, NG) are important public health problems in many developed and developing countries [1,2,3]. According to the World Health Organization (WHO)’s most recent estimates, there were an estimated 131 million new cases or 127 million prevalent cases of CT and 78 million new cases. Chlamydial & gonococcal infection among women in China. The funders had no role in study design, data collection and analysis, decision to publish, or preparation of the manuscript
