The purpose of this study was to explore the epidemiology of infection with multiple HPV types in adolescents and its association with demographic, behavioral and biological variables, as well as with cytological abnormalities. Methods: This community-based study included 432 sexually active females between 15 and 19 years of age. Genotyping for 30 HPV types was performed using a reverse blot strip assay/restriction fragment length polymorphism. Unconditional multivariate logistic regression was performed to identify factors significantly associated with HPV infection. The association between HPV infection and cytological abnormalities was calculated using a prevalence ratio. Results: The most common HPV types detected were 16, 51, 31, 52 and 18. Of the 121 HPV-positive women, 54 (44.6%) were infected with multiple HPV types. Having more than one lifetime sexual partner was associated with infection with any HPV infection, single HPV infection, and infection with multiple HPV types. The presence of cytological abnormalities was associated with infection with multiple HPV types. Conclusions: Co-infecting HPV genotypes occur in a high proportion of sexually active adolescents. Socio-demographic or sexual behavior factors associated with single HPV infection were similar to those associated with multiple HPV types. The higher risk of cytological abnormalities conferred by infection with multiple HPV types suggests a potential role of co-infection in the natural history of HPV infection

We aimed to estimate the prevalence and risk factors for Chlamydia trachomatis, Neisseria gonorrhoeae, and Treponema pallidum infection among young non-pregnant women in non-clinical settings in middle-sized cities of Central Brazil. Methods: A cross-sectional community-based sample of 1072 participants was included. Sexually active women (64.9%) provided first-catch urine samples for PCR investigation of chlamydial and gonococcal infection. Syphilis was tested in serum. Univariate analysis investigated risk factors for chlamydial infection. Multivariate logistic regression included associations with a p-value <0.20. Results: The mean age of participants was 18 years; 73.2% reported unprotected intercourse, 37.6% were married/cohabiting, and 5% reported a previous STI. Prevalence rates of C. trachomatis, N. gonorrhoeae, and T. pallidum were 9.6% (95% confidence interval (CI) 7.4–12.4%), 0.7% (95% CI 0.2–1.9%), and 0.15% (95% CI 0.0–0.7%), respectively. After adjustments, being <20 years old (adjusted odds ratio (aOR) 1.90, 95% CI 1.07–3.37) and having three or more lifetime sexual partners (aOR 2.57, 95% CI 1.46–4.53) were associated with the risk for chlamydial infection. Conclusions: We observed a high prevalence of chlamydial infection and sexual risk behaviors in this population. These findings are important to guide screening strategies in Brazil
