Awareness, knowledge and attitudes of human papillomavirus infection, screening and vaccination: a survey study in Greece

Abstract Purpose To evaluate the awareness and existing knowledge of a portion of the Greek population about prevention, screening, and HPV vaccination. Methods A questionnaire designed in Google forms has been distributed through social media between June 2021 and December 2021 in men and women aged > 16 years old. Statistical analysis was performed using the SPSS 20.0 program. Inferential analysis was performed to evaluate differences in responses among men and women. Results We enrolled 2685 participants. Of those, 2285 were women, 386 were men, while 14 respondents chose not to respond to this question. Various age groups were detected with those aged between 26 and 30 years old being the predominant one. Participants with a higher education constituted 36.5% of the population. Most respondents were married (59.8%). In socioeconomic terms 75.5% of participants were employed whereas, monthly income ranged between 1000 and 1500 euros in the predominant group (36.8%). Only 40% of females and 3.9% of males were vaccinated against HPV. Adolescent immunization, acceptability rates reached 92.7% among female and 82.1% among male responders. Although, only a small proportion of the participants were not aware of the existence of HPV, 24.1% of males and 23.4% of females had the impression that condom use may provide absolute immunity to HPV and only 51.6% of males and 60.4% of females were aware about the high prevalence of HPV in the general population. Logistic regression analysis indicated that male participants as well as those aged > 50 years and those choosing to reject vaccination had decreased knowledge of the basic pathophysiology of HPV infection, as well as knowledge related to the existence and use of HPV DNA as a screening tool and the existence and efficacy of HPV vaccination. Conclusion Our results indicate that although awareness of the existence of HPV infection is high in Greek general population, the actual perception of the pathophysiology of transmission and importance of HPV testing and vaccination is low. Targeting specific population groups is essential to help increase HPV coverage and screening.

The effect of the delivery mode on the evolution of cervical intraepithelial lesions during pregnancy. A meta-analysis

The aim of the present study was to evaluate the impact of the mode of delivery on the natural evolution of cervical squamous intraepithelial lesions in pregnant patients. Α systematic search was conducted in Medline (1966-2021), Cochrane Central Register of Controlled Trials CENTRAL (1999-2021), Scopus (2004-2021), Google Scholar (2004-2021) and Clinicaltrials.gov (2008-2021) along with the reference lists of electronically retrieved full-text papers. All the studies that investigated the correlation of the mode of delivery with the natural evolution of cervical squamous intraepithelial lesions of patients during pregnancy, were included in the present meta-analysis. Eight retrospective studies were finally included, comprising 813 patients whose premalignant lesions were evaluated cytologically, of whom 685 delivered via the vaginal route, and 233 patients whose squamous intraepithelial lesions were evaluated histologically, of whom 162 delivered vaginally. The methodological quality of the included studies ranged between moderate and serious. Regression rates were comparable among women that delivered with caesarean section compared to patients that delivered vaginally, both in the cytological (OR 1.32, 95% CI 0.56, 3.12) and in the histological evaluation (OR 1.87, 95% CI 0.50, 6.96) of the lesions. Subgroup analysis revealed consistent results for all subgroups of premalignant lesions. Finally, the results observed for both the persistence and the progression rates of these lesions were proportional. Our meta-analysis suggests that the delivery mode does not alter the natural evolution of squamous intraepithelial lesions in pregnant women and therefore their presence should not determine the mode of delivery.
