IDDF2024-ABS-0049 Gender differences associated with colorectal cancer screening uptake in Singapore

<h3>Background</h3> Colorectal cancer (CRC) stands as the most prevalent cancer in Singapore. Early detection is crucial for effective treatment. Yet, screening rates remain at around 30% a decade from the inception of the national screening programme. This study aimed to explore how gender influences screening intentions and uptake among community-dwelling individuals. <h3>Methods</h3> Average-risk individuals (n=529) were purposively sampled from a primary care institution between January 2020 and February 2023. Self-reported data on demographics, health beliefs, knowledge of CRC symptoms and health behaviours for CRC prevention, screening information sources and screening status were collected. <h3>Results</h3> Only 34% were screen-current (i.e. have undergone a FIT test, sigmoidoscopy or colonoscopy within the past 10 years). There were significantly more screen-current men (40.6%) than women (28.6%; <i>p</i>=0.004). Men who were screen-current were more likely to feel susceptible (Odds Ratio (OR), 1.46, 95% Confidence interval (CI): 1.04–2.05, <i>p</i>=0.029) and received cues to screen (OR, 1.31, 95%CI: 1.09–1.57, <i>p</i>=0.003). Women, on the other hand, were found to be more likely screen-current if they were not currently working (OR, 2.14, 95%CI: 1.06–4.30, <i>p</i>=0.033) and received cues to screen (OR, 1.25, 95%CI: 1.06–1.48, <i>p</i>=0.007). <h3>Conclusions</h3> This study reveals a significant gender disparity in CRC screening uptake in Singapore. Gender-specific interventions, utilising tailored outreach strategies, could potentially narrow the CRC screening gap between genders, enhancing early detection and treatment outcomes.
