Objectives: Cervical cancer has a high mortality rate among women worldwide. Although cervical cancer screening (CCS) is an effective strategy in reducing mortality of the disease, inequalities in accessing screening exist, particularly among migrant women. This study aims to characterize migrant women’s participation in CCS and determine factors associated with non-attendance to CCS. Methods: A cross-sectional study based on a web-based survey targeting adult migrant women living in Portugal was conducted. Prevalence of non-attendance to CCS was examined, and its associations with socioeconomic, migration-related, and health-related factors were determined using adjusted logistic regression models. Results: A total of 1100 migrant women were included in the study. Prevalence of CCS non-attendance was 24.5%. CCS non-attendance was associated with younger age, being born in Africa or Asia, being single/divorced/widowed, never having had a GP appointment in Portugal and not having regular gynecology appointments. Being born in South and Central America, shorter length of stay in Portugal, having had HPV vaccination, and not having children are associated with CCS attendance. Conclusion: These findings point out that an important percentage of migrant women do not attend CCS. Strategies to increase participation should be developed, considering the inequalities identified and designed to target the specific needs of migrant women to improve their CCS attendance and increase cervical cancer prevention.

Background Cervical cancer is a common disease which can be effectively and timely detected by cervical cancer screening. However, access to cervical cancer screening is unequal, and it is known that migrant women have a lower attendance to cervical cancer screening. These inequalities are associated with several factors, including attitudes and beliefs of the women regarding screening practices, which prevents them from participating. This study aims to explore the attitudinal barriers to cervical cancer screening among migrant women in Portugal. Methods A web-based cross-sectional survey was conducted with 1100 migrant women residing in Portugal. Women were recruited through social media platforms. The survey included items on socioeconomic characteristics, cervical cancer screening history and an 11-item attitudinal questionnaire to assess attitudinal barriers. Logistic regression models were used for statistical analysis. Results The attitudinal barriers to CCS most often reported by participants were fear of the test result (25.3%), worry about seeing a male health professional (23.8%), perceiving the test as painful (23.1%), embarrassment (18.5%), difficulties scheduling the test (14.3%), and having a negative experience in screening (12.4%). Low perceived need in absence of symptoms and lack of motivation to be screened were reported by less than 5% of the women. However, the results suggest that most of the attitudinal barriers with higher agreement percentage have no association with cervical cancer screening attendance. Among all the attitudinal barriers, low perceived need of screening and lack of motivation were associated with CCS non-attendance. Conclusions Based on the findings, out of all the factors analyzed, low perceived need of screening and lack of motivation are the most relevant factors associated with non-attendance among migrants in Portugal. Promoting health literacy and empowering women with knowledge about benefits of screening may help overcoming these barriers. Therefore, this study provides a foundation for stakeholders on which areas should be prioritized when developing strategies aiming to reduced cervical cancer screening non-attendance among migrant women.
