The aim of this study was to analyze the level of, and income-related inequalities in, screening attendance, in Portugal for population-based screening programs.Methods: Data from the Portuguese Health Interview Survey 2019 was used. Variables included in the analysis were self-reported: mammography, pap smear test, fecal occult blood test. Prevalence and concentration indices were computed at national\/regional level. We analyzed: up-to-date screening (within recommended age\/interval), under-screening (never or overdue screening), and over-screening (due to frequency higher than recommended or screening outside target group).Results: Up-to-date screening rates were 81.1%, 72%, and 40%, for breast, cervical and colorectal cancer, respectively. Never-screening was 3.4%, 15.7%, and 39.9%, for breast, cervical, and colorectal cancer, respectively. Over-screening related with frequency was highest for cervical cancer; in breast cancer, over-screening was observed outside recommended age, affecting one third of younger women and one fourth of older women. In these cancers, over-screening was concentrated among women with higher income. Never-screening was concentrated among individuals with lower income for cervical cancer and higher income for colorectal cancer. Beyond the recommended age, 50% of individuals never underwent screening for colorectal cancer and 41% of women never underwent screening for cervical cancer.Conclusion: Overall, screening attendance was high, and inequalities were low in the case of breast cancer screening. The priority for colorectal cancer should be to increase screening attendance.<\/jats:p>","DOI":"10.20344\/amp.19443","type":"journal-article","created":{"date-parts":[[2023,6,19]],"date-time":"2023-06-19T10:21:33Z","timestamp":1687170093000},"page":"577-587","source":"Crossref","is-referenced-by-count":5,"title":["Picturing Prevalence and Inequalities in Cancer Screening Attendance to Population-Based Programs in Portugal"],"prefix":"10.20344","volume":"36","author":[{"given":"Carlota","family":"Quintal","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Micaela","family":"Antunes","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"8464","published-online":{"date-parts":[[2023,6,19]]},"reference":[{"key":"3512","unstructured":"World Health Organization.
