Abstract

Objective: to analyze the factors associated with the occurrence of Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma genitalium and Trichomonas vaginalis in pregnant women followed up in Primary Health Care. Method: a cross-sectional study of 302 pregnant women aged between 15 and 49 years. Vaginal secretion samples were collected for molecular biology detection of chlamydia, gonorrhea, mycoplasma and trichomoniasis; a structured questionnaire was applied with sociodemographic, behavioral, obstetric and clinical data, and results of rapid tests (Human Immunodeficiency Virus, Syphilis, Hepatitis B and C). Analysis was carried out using STATA 15.0 software. Results: the prevalence rates found were: Chlamydia trachomatis (11.6%), Mycoplasma genitalium (9.6%), Neisseria gonorrhoeae (1.7%) and Trichomonas vaginalis (3.6%). Age under 25 (adjusted odds ratio=2.06), presence of symptoms (adjusted odds ratio=1.99), absence of a steady partner or up to one year of relationship (adjusted odds ratio=2.64) increased the chance of having at least one infection. Conclusion: this study describes the high global prevalence of curable sexually transmitted infections in pregnant women in Primary Health Care. Knowing the prevalence of these infections in pregnant women and the main determinants are essential for reorganizing prenatal care and reducing pregnancy, puerperal and fetal complications.
