Objective. To determine the prevalence of Chlamydia trachomatis
(CT), Neisseria gonorrhoeae (NG) and syphilis in pregnant
women.
Methods. A cross-sectional study was conducted among women
attending antenatal care clinics (ANCs). Blood samples were
tested for syphilis using the rapid plasma reagin (RPR) and
treponemal haemagglutination (TPHA) tests; CT and NG
were diagnosed using a manual polymerase chain reaction
assay on first-void urine samples. A socio-demographic
questionnaire was completed. Results were compared with
previous published data on sexually transmitted infection (STI)
prevalence in Mozambique.
Results. Blood and urine samples were collected from 1 119
and 835 women, respectively. The prevalence of CT was 4.1%,
and that of NG 2.5%. The RPR test was positive in 5.2% of the
women, and 7.1% had a positive TPHA test. Active syphilis
was found in 4.7%. In univariate analysis, CT was associated
with having had any level of education (
