Background Historically, studies suggested that immigrants acquire the risk of colorectal cancer (CRC) as US-born persons within the same generation. CRC risk of immigrants is largely unknown in this era of cancer screening and widespread immigration. We investigated the association of place of birth and cancer beliefs with uptake of CRC screening.Methods Th e 2007 Health Information National Trends Survey was used and 4,299 respondents (weighted population size=81,896,392) who were 50 years and older (3,960 US-born and 339 foreign-born) were identified. We defined being current with CRC screening guidelines as the use of fecal occult blood test within 1 year, sigmoidoscopy within 5 years, or colonoscopy within 10 years. We compared being up-to-date with CRC screening among foreign-born versus US-born respondents. Logistic regression models were used to calculate odds ratios (OR) and 95% confidence intervals (CI).Results Overall, 2,594 (63.3%) US-born and 208 (52.8%) foreign-born respondents were current with CRC screening. Foreign-born respondents were less current in unadjusted model (OR 0.65; 95%CI: 0.50-0.85) but became non-statistically significant after adjustment (OR 0.79; 95%CI: 0.51-1.24). Respondents who believed that screening finds cancer when it is easy to treat (OR 2.85; 95%CI: 1.44-3.61), those who believed that cancer can be cured when detected early (OR 1.56; 95%CI: 1.20-2.00), and those who worry about getting cancer (OR 1.34; 95%CI: 1.10-1.61) were likely to be current with CRC screening. However, respondents with fatalistic beliefs were borderline less likely to be current (OR 0.82; 95%CI: 0.65-1.04).Conclusion There is a need to improve education on CRC screening, particularly among foreignborn adults.Keywords Cancer screening, colorectal cancer, beliefs, place of birth, nativityAnn Gastroenterol 2016; 29 (3): 336-340
