Background and study aims: Colorectal cancer.incidence ranks third among all cancers in Switzerland. Screening of the general population for colorectal cancer by faecal occult blood test (FOBT) or endoscopy (sigmoidoscopy or colonoscopy) could decrease colon cancer incidence and mortality. The aim of this study was to analyse the use of these methods and to describe colorectal cancer screening in the general Swiss population aged 40 years and older. Methods: Prevalence estimates and 95% confidence intervals were calculated for endoscopy and FOBT use in general and their utilization for colorectal cancer screening. Uni- and multivariable logistic regression analyses were applied to evaluate the association between screening use and sociodemographic and socioeconomic characteristics, utilization levels of the health care system and lifestyle factors. Data were obtained from the 2007 Swiss Health Interview Survey (SHIS). Results: The prevalence of general FOBT and endoscopy use was 30.7% (95% Cl: 29.6-31.7) and 24.8% (95% Cl: 23.9-25.8) respectively. For colorectal cancer screening the calculations indicated a prevalence of 5.9% (95% Cl: 5.4-6.5) for FOBT and of 5.1 % (95% Cl: 4.6-5.6) for endoscopy. Major determinants of colorectal cancer screening use were found to be male gender, the number of physician visits during the past year, having a private health insurance and having other cancer screening done. Screening by endoscopy was associated with a high income. Conclusions: In Switzerland the prevalence of colorectal cancer screening by FOBT and endoscopy among average-risk older adults ([more or less] 40years) is low and policymakers should consider ways to improve screening rates.
