Abstract
BACKGROUND: Colorectal cancer (CRC) is one of the most common types of gastrointestinal cancers. This study aimed to determine the demographic characteristics and their relationships with the results of the first screening program for CRC in people over 50 years old in northern Iran. METHODS: This cross-sectional study was conducted in 2016 on 924 eligible people over 50 years old. Initial screening was done by IFOBT and then colonoscopy was performed if the results were positive. The demographic characteristics of individuals including age, sex, place of residence, marital status, body mass index (BMI) and education level were investigated with the results of the colonoscopy and the test results. RESULTS: The mean age of participants was 59.38 years, and the participation of women (57.0%) and rural residents (54.2%) were higher in the screening program. According to the demographic variables, age was considered as a strong independent predictor variable, so that the prevalence of positive test results was more than 2 times higher in subjects older than 70 compared with subjects aged ≤60 (OR =2.05; 95% CI, 1.18-3.55, P=0.010). Also, the chance of positive test result in the age group ≤55 years old was 23%, with an increase of 64% in the age group above 75 years (P<0.001). Among the positive test subjects, 118 cases underwent colonoscopy. CONCLUSIONS: The prevalence of IFOBT positivity was increased with age. Therefore, given the aging population of the country, it is recommended to emphasize on the screening of older people in the general population.
