BACKGROUND: Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) infections in pregnancy contribute to adverse perinatal outcomes. We identified predictors of CT and/or NG infection among pregnant Kenyan women.
METHODS: Women without HIV were enrolled at 2 antenatal clinics in Western Kenya. Both CT and NG were assessed using endocervical samples for nucleic acid amplification tests. Poisson regression models were used to evaluate potential CT/NG risk factors. Classification and regression trees were generated to evaluate the joint effects of predictors.
RESULTS: Overall, 1276 women had both CT and NG assessments. Women enrolled at a median of 26 weeks' gestation (interquartile range, 22-31 weeks), median age was 22 years (interquartile range, 19-27 years), and 78% were married. In total, 98 (7.7%) tested positive for CT/NG: 70 (5.5%) for CT and 32 (2.5%) for NG, 4 of whom (0.3%) had coinfections. Two-thirds (66%) of CT/NG cases were asymptomatic and would have been missed with only syndromic management. Risk factors of CT/NG included age <22 years, crowded living conditions, being unmarried, being in partnerships for <1 year, abnormal vaginal discharge, sexually transmitted infection history, and Trichomonas vaginalis diagnosis ( P < 0.1). Classification and regression tree analyses identified unmarried women <22 years in relationships for <1 year as 6.1 times more likely to have CT/NG compared with women without these characteristics (26% vs. 6%, adjusted prevalence ratio = 6.1, 95% confidence interval = 3.55-10.39, P < 0.001).
CONCLUSIONS: Chlamydia trachomatis / Neisseria gonorrhoeae was frequently asymptomatic and common among young unmarried women in newer partnerships in this cohort. Integrating CT/NG testing into routine antenatal care may be beneficial, especially for young women in Kenya.
