Chlamydial and gonococcal infections in Curacao: prevalence and determinants

ABSTRACT

OBJECTIVE: To determine prevalence and determinants of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) infections among asymptomatic women and men in Curacao. DESIGN AND METHODS: This was a cross-sectional population-based study. Urine samples (n=579) were collected from Antillean people, > 18 years, randomly selected from participants of a 1994 population survey (the Curacao Health Study, n=2,248). For the detection of CT and Erasmus Medical Center, Rotterdam. RESULTS: CT and NG infections were found in 6.1 percent and 1.0 percent of samples, respectively. Concomitant CT and NG infection did not occur. Most CT infections were found in persons <44 years of age, the highest prevalence was found in the 18-24 year age group, 17.4 percent (13/75). In contrast, most NG infections were found in persons >44 years. CT infection, but not NG infection, was correlated with indices of low socio-economic status. Multiple regression confirmed the association of CT infection with age and socio-economic class. CONCLUSION: In Curacao, CT and NG infections are not epidemiologically linked. CT infection is highly prevalent and calls for a screening-intervention model based on prevalence and risk factors. (Au)
