Addressing Social Inequalities in Cancer Screening Uptake Among Underserved Populations
核心洞察
Cancer (搜索) screening programs can reduce morbidity and mortality through early detection, yet participation remains uneven across social groups, contributing to disparities in cancer outcomes.
Underserved populations—including people with chronic conditions, LGBTQ+ communities, individuals experiencing homelessness, migrants, and people with disabilities—face barriers such as stigma, discrimination, and limited healthcare access.
A new global research initiative seeks to identify structural, cultural, economic, and healthcare-system factors influencing screening access and to evaluate strategies that have successfully improved participation.
Despite the demonstrated benefits of cancer (搜索) screening, significant inequalities in uptake persist globally, particularly among underserved groups such as people living with chronic conditions, LGBTQ+ communities, individuals experiencing homelessness, migrants, and people with disabilities. These populations often face barriers including stigma, discrimination, competing health priorities, and limited access to healthcare, resulting in lower participation and poorer cancer outcomes.
A new global research initiative aims to advance understanding of the factors driving these disparities and identify effective strategies to improve equitable access. By bringing together international evidence on interventions, policies, and service innovations, the effort seeks to inform more inclusive, user-centered cancer (搜索) screening programs and reduce inequalities in cancer prevention and early diagnosis.
The Scope of Screening Disparities
While cancer (搜索) screening programs can reduce morbidity and mortality through early detection, participation remains uneven across social groups, contributing to disparities in cancer outcomes. The research initiative places particular attention on populations that are often overlooked in public health research and policy, focusing on "hidden" and underserved populations, including people living with chronic health conditions, LGBTQ+ communities, individuals experiencing homelessness, and other groups facing social exclusion.
These populations frequently encounter barriers such as stigma, discrimination, competing health priorities, service accessibility challenges, and mistrust of healthcare systems. The initiative explicitly invites contributions from diverse international contexts, as well as research aimed at identifying the structural, cultural, economic, and healthcare-system factors that influence screening access and engagement.
Research Themes and Priorities
The initiative welcomes articles addressing a broad range of themes, including social, cultural, economic, and structural determinants of screening participation; the impact of multimorbidity and mental health conditions; and experiences of stigma, discrimination, and healthcare exclusion. Additional areas of focus include the influence of healthcare systems and screening policies on equitable access, intersectionality, gender, and the role of identity in healthcare engagement.
The research scope also encompasses innovative and community-engaged interventions to improve screening uptake, digital health tools, outreach models, and participatory approaches. Methodological advances for identifying and studying "hidden" populations, as well as international comparisons and cross-country case studies informing inclusive screening policy, are likewise encouraged.
Toward Equitable Cancer Care
The initiative particularly encourages contributions focusing on underserved and often overlooked populations, including people living with chronic health conditions, LGBTQ+ communities, individuals experiencing homelessness, migrants, ethnic minority groups, people with disabilities, and other socially excluded populations. Original research, reviews, methodological papers, policy analyses, and perspectives examining social inequalities in cancer (搜索) screening uptake across diverse global contexts are all welcomed.
By consolidating international evidence on the determinants of screening disparities and effective strategies to improve participation, the research effort aims to support the development of more inclusive screening programs and contribute to reducing inequalities in cancer (搜索) prevention and early diagnosis worldwide.
