Brief Summary

It is estimated that there are about 1.4 million patients with colorectal cancer (CRC) worldwide, with a rising trend in CRC incidence in many Asian Pacific countries. In Hong Kong, colorectal cancer ranks first in cancer incidence and second in cancer mortality based on data from 2014. Recent guidelines from USA, Europe and Asia Pacific region recommend CRC screening for average-risk asymptomatic individuals starting at age 50. Fecal immunochemical tests (FIT), is one of the recommendation as first-line modality for CRC screening. Since yearly testing is recommended to maintain programmatic effectiveness longitudinal adherence is a critical component of FOBT-based screening programs. Our previous study conducted in Hong Kong showed that the rate of compliance with CRC screening was declining since the first year of enrolment8. In recent years, social media (SM) has become an increasingly popular source of health information. By providing an easily accessible and interactive channel of communication between reviewers and information providers, it has potential values for affecting public health. However, the effects of SM on the compliance of CRC screening by FIT has not yet been studied. WhatsApp Messenger, is the most popular social media messaging app worldwide. This randomized controlled study will investigate the effect of WhatsApp vs no reminder on the compliance of CRC screening by FIT.
