Factors affecting young women's participation in organized cervical cancer screening and non-organized testing – A population-based survey study

Objectives Organized cervical cancer screening reduces cervical cancer incidence and mortality and is widely implemented across Europe. However, non-organized cervical cancer testing remains common. Frequent testing may lead to overdiagnosis and unnecessary treatment, especially among young women. This study aims to identify factors influencing young women's participation in organized cervical cancer screening and non-organized cervical cancer testing. Methods We surveyed 1411 women aged 15–35 living in Finland, assessing their knowledge and attitudes toward cervical cancer testing. Survey responses were linked to sociodemographic registry data and cervical cancer testing records. Descriptive statistics of survey responses and logistic regression were used to identify factors influencing participation in both organized screening and non-organized testing. Results Human papillomavirus vaccination status, medical contraception use, and gynecologist visit frequency were key predictors of non-organized testing. Human papillomavirus-vaccinated women were 50% less likely to undergo non-organized testing compared to those unvaccinated. Medical contraception users were 5.3 times more likely compared to non-users, and frequent gynecologist visitors were 1.5 times more likely to undergo non-organized testing compared to infrequent visitors. For organized screening, women with tertiary education were 4.1 times more likely to participate than those with primary education. Women appreciated the flexibility in screening times and locations. Human papillomavirus awareness was high with 91.3% of respondents having heard of the virus. Conclusions To address non-organized testing among young women, comprehensive education about human papillomavirus and cervical cancer screening is essential, both for screened women and healthcare professionals. Aligning screening practices with women's preferences may improve adherence to organized screening, ultimately benefiting public health outcomes.
