Abstract
OBJECTIVE To determine the prevalence of HPV and investigate factors associated with the infection in women in the city of Francisco Beltrão, southwest Paraná, attending the public health system. METHODS This cross-sectional study included 324 women, aged between 18 and 65 years, who were attending public health services for routine gynecological consultation. Interviews were conducted to obtain information about socioeconomic, sexual, gynecological, and life habits. After performing the Papanicolaou test, endocervical brush was employed to detect HPV by polymerase chain reaction with the primers MY09-MY11. RESULTS The prevalence of HPV was 6.8%, out of which 58.3% presented with cytopathologic alterations. And the presence of current cervical alterations can increase the chances of having HPV by almost 33 times (ORadj: 32.688; p < 0.001), recent vaginal infection increased the chances of HPV infection by 2.7 times (ORadj: 2.773; p = 0.04). The non-white ethnicity increased HPV infection chances threefold (ORadj: 3.058; p = 0.039). CONCLUSION The main finding was low prevalence of HPV infection. Factors that may be linked to HPV infection were cervical alterations, recent vaginal infection, and women's ethnicity.

Abstract
Human papillomavirus(HPV) infection is a necessary factor for the development of cervical cancer. The HPV vaccine is currently available, but there is still a lack of large-scale research on the distribution and risk factors of HPV. The aim of this study is to investigate the genotype distribution and risk factors of HPV infection in Yangqu which is located in North China. This study enrolled 10086 women aged <65 years from Yangqu County. HPV genotypes were identified via standard HPV DNA testing. The overall prevalence of HPV infection was 8.92%. The prevalence of high-risk HPV types was 8.80%, and it was 0.38% for low-risk HPV types. Single genotype infection accounted for 67.91% in HPV-positive cases. The most common HPV genotypes were HPV-16, -52, and -58. HPV-18 was only the 11th most common type in HPV-positive cases. Women ≥50 years of age had the highest prevalence rate of HPV, and women <30 years had the lowest prevalence rate. The distribution of HPV genotypes also varied among the three age groups: <30, 30-49, and ≥50 years. The risk factors that contributed to the rate of HPV infection included low educational level, low income, smoking, age at first sexual encounter <23 years old, and number of births ≥3 times. This large routine clinical practice report of HPV prevalence and genotype distribution revealed the characteristics of HPV infection-type distributions in Shanxi Province, which should be considered in formulating comprehensive prevention strategies including vaccination for cervical cancer in China.

Jongen VW, van Santen DK, Alberts CJ, Schim van der Loeff MF. Estimating incidence rates of grouped HPV types: A systematic review and comparison of the impact of different epidemiological assumptions. PAPILLOMAVIRUS RESEARCH (AMSTERDAM, NETHERLANDS) 2019; 8:100187. [PMID: 31600572 PMCID: PMC6804437 DOI: 10.1016/j.pvr.2019.100187] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/25/2019] [Revised: 10/04/2019] [Accepted: 10/06/2019] [Indexed: 01/01/2023]
Abstract
BACKGROUND Some studies on human papillomavirus (HPV) provide not only type-specific incidence rates (IR), but also IRs of HPV groupings (e.g. the nonavalent grouping). We made an inventory of the different approaches used to calculate such IRs and assessed their impact on the estimated IRs of HPV groupings. METHODS We performed a systematic review assessing all approaches used in literature to estimate IRs. Subsequently we applied these approaches to data of a Dutch cohort study on HPV in men who have sex with men (H2M). IRs were estimated for six different HPV groupings. RESULTS The systematic review yielded six different approaches (A-F) for estimating the IRs, varying in exclusion criteria at baseline, and the definitions of an incident event and person-time. Applying these approaches to the H2M dataset (n = 749), we found differences in the number of participants at risk, number of incidents events, person-time, and IR. For example, for the nonavalent grouping, depending on the approach chosen, the IR varied between 3.09 and 6.54 per 100 person-months. CONCLUSION In published studies different epidemiological assumptions are used to estimate IRs of grouped HPV types, leading to widely differing estimates of IRs. IRs between different studies may therefore not be comparable.

Is Online Partner-Seeking Associated with Increased Risk of Condomless Sex and Sexually Transmitted Infections Among Individuals Who Engage in Heterosexual Sex? A Systematic Narrative Review. ARCHIVES OF SEXUAL BEHAVIOR 2019; 48:533-555. [PMID: 30155796 DOI: 10.1007/s10508-018-1235-2] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/11/2016] [Revised: 05/11/2018] [Accepted: 05/14/2018] [Indexed: 06/08/2023]
Abstract
Use of Internet websites and mobile applications to meet potential romantic and sexual partners is becoming increasingly popular. While the Internet might foster better communication and sexual negotiation between partners, it can also be a deceptive environment that instigates and accelerates sexual risk-taking. Given the complexities of the Internet, it is critical to examine the association between risky sexual behaviors (RSBs) and online partner-seeking. Five databases (i.e., Google Scholar, PubMed, PsycINFO, Web of Science, and Ovid Medline) were searched for articles published before September 10, 2017, that examined the association between online partner solicitation (either for romantic and/or sexual reasons) and RSBs. Studies were eligible for inclusion if they were empirical papers published in English-language peer-reviewed journals looking at samples of online partner seekers who practice heterosexual sex (with a comparison group) and reporting either condom use or sexually transmitted infections (STIs) status, which were the two primary outcomes. A total of 25 studies met the criteria to be included in our review. Results from this literature search do not indicate a clear association between online partner-seeking and condom use or STI status. Potential moderators (i.e., age, gender, reasons for online partner solicitation, duration of Internet correspondence, and Internet modalities) that should be included in future research were identified. Sexual health prevention efforts should address methods to negotiate safe practices between sexual partners and to encourage healthy non-virtual relationships, particularly among vulnerable populations.
