Background Neisseria gonorrhoeae (NG) is a sexually transmitted infection having repercussions on reproductive health and impact on the fetus. Our goal was to estimate the prevalence of and risk factors for NG in young parturient women in Brazil.
Methods A national cross-sectional study among parturient women, aged 15–24, attending Brazilian public hospitals was performed in 2009. Participants answered a questionnaire including demographic, behavioural and clinical data. A sample of urine was collected and screened for NG and Chlamydia trachomatis (CT), using PCR.
Results A total of 2400 women were selected and 2071 (86.3%) participated in the study. Mean age was 20.2 years (SD 2.7). A total of 59.1% had up to 8 years of schooling and 93.3% reported an income under US$ 500. Ninety-five per cent attended antenatal care. Prevalence of NG was 1.0% (95% CI 0.6% to 1.4%) and 4% of women infected with NG also had CT infection. First sexual intercourse was reported under 15-years old by 32.8%; 5% reported previous STI; 0.8% were commercial sex workers and 6.0% used illicit drugs. NG associated factors in the final logistic model were—being single [OR=3.2 (95% CI 1.27 to 8.01)]; having more than one sexual partner in lifetime [OR=1.6(95% CI 1.13 to 2.26)]; and CT infection [OR=7.7(95% CI 2.99 to 19.91)].
Conclusions Although this study shows a low prevalence of NG infection among young pregnant women in Brazil, they presented STI risk factors that justify include STI counselling for this population.
