High Burden of Chlamydia trachomatis and Human Papillomavirus Infections in Low-Income Female University Students from Public Schools in the Brazilian Amazon.

Sexually transmitted infections (STIs) caused by C. trachomatis and HPV are the most prevalent worldwide. College students are characterized by being young women of reproductive age who may have risky sexual behavior. To describe the prevalence and factors associated with endocervical infection by C. trachomatis and HPV in college women in the Brazilian Amazon. Endocervical secretions were collected. The ompA gene of C. trachomatis and the L1 gene of HPV were detected. The Chi-square test, Fisher's exact test, G test, Odds Ratio, and Multiple Logistic Regression were used with 95% confidence interval and p ≤ 0.05. The overall prevalence of endocervical infection by C. trachomatis was 8.3% (25/302) and by HPV was 28.9% (87/302). Low income was associated with sexually transmitted infection by C. trachomatis (14.8%, p = 0.0336). Those under 25 years old had twice the chance of HPV infection [39.3%, (OR: 2.6989), 95% CI: 1.6054-4.5371, p = 0.0002], as did women without children [31.8%, (OR: 2.333), CI: 1.1235-4.8461, p = 0.0307]. Women who did not study in a public school had 63% reduced risk of acquiring HPV infection [45.8% (OR: 0.3713), CI: 0.1951-0.7064, p = 0.0035]. C. trachomatis and HPV infections were present in low-income, childless young women who attended public schools, requiring the intensification of STI prevention policies in the Amazon region.
