Objectives: To determine the prevalence and risk factors for chlamydial infection in cross-border truck drivers (CBTDs).
Methods: 225 Hong Kong-based CBTDs were screened for chlamydial infection. Associations between infection and potential risk factors were determined by questionnaire.
Results: 8.5% of drivers were positive for chlamydial infection. Of 62% of drivers reporting recent sex with commercial sex workers (CSWs), 39% had not used condoms. 75% of drivers with extramarital sex partners (ESPs) also frequented CSWs, and 47% of this group had not used condoms with CSWs. 43.3% PCR-positive cases reported symptoms. No risk factor was associated with chlamydial infection after adjustment, though "had sex with ESPs" approached significance.
Conclusions: Prevalence of chlamydial infection among CBTDs was not strikingly high, although drivers engaged in sex with both ESPs and CSWs, with many admitting unprotected intercourse. Findings highlight the importance of promoting safe sex to truck-drivers.
