Public Knowledge, Attitudes, and Barriers to Gastric Cancer Screening in the UAE: Implications for Improved Practices

Introduction: Gastric cancer is a major cause of cancer-related mortality worldwide, and early detection through screening can improve outcomes. In the United Arab Emirates (UAE), incidence is relatively low, but late-stage diagnosis, limited public awareness and no dedicated national screening programme remain concerns. This study examined knowledge, attitudes, perceived barriers and factors associated with screening uptake among UAE residents. Theory: The study was informed by public health approaches to cancer prevention and early detection, focusing on how knowledge, attitudes, perceived risk, physician recommendation and access shape screening behaviour and engagement with screening. Methods: A cross-sectional bilingual online survey was conducted between October 2024 and February 2025 using convenience sampling. In total, 959 UAE residents aged 18 years or older completed the questionnaire. Data were analysed using descriptive statistics and binary logistic regression. Results: Participants had moderate knowledge of gastric cancer, with a median score of 18 out of 29, and generally positive attitudes towards screening. However, only 21.5% had undergone screening. Key barriers included lack of interest, absence of physician advice, fear of results and limited awareness. Discussion: Findings highlight the need for culturally tailored education, stronger clinician engagement and more accessible screening pathways to improve participation.
