Forty-nine FDRs aged 40－75 years from the CRC patients who underwent the colorectal cancer surgery in the Department of Colorectal Surgery of our hospital from January 2019 to December 2019 and were pathologically diagnosed as CRC after the surgery were selected by target sampling method.The questionnaire survey was conducted in the FDRs and the survey data were collected to analyze the cognitive status of the FDRs on CRC screening.

Among the FDRs of CRC patients， 21 cases were 40－50 years old and 28 cases were 50－75 years old；27 males and 22 females；31 children， 10 siblings， and 8 parents. Only 26.5% （13/49） of the FDRs were aware of the “increased risk of CRC in FDRs” and only 22.4% （11/49） of participants had “had a colonoscope in the past 5 years”.75.5%（37/49） of the FDRs did not have “medical staff recommended colonoscope over 40 years old”. The awareness rate of “increased risk of CRC for FDRs” and “had a colonoscope in the past 5 years” among the FDRs aged 40－50 years old， living in urban， college degree or above were higher than those aged 51－75 years old，with below college and rural residents. Among the 38 FDRs of CRC patients who had not undergone colonoscope in the past 5 years， the main reasons which affected the FDRs to do the colonoscopy screening were “no physical symptoms， no need to undergo colonoscope”， fear of colonoscope process， and the tedious and time-consuming colonoscope.Of the 38 FDRs of CRC patients，22（57.9%） cases changed their cognition and were willing to undergo colonoscopy after the communication.

The cognition of CRC patients’ FDRs on the CRC screening is seriously insufficient. It is an important measure to increase the CRC screening rate to strengthen the health education of CRC screening with the support of medical insurance policy.
