Colorectal cancer prevention and intentions to use low-dose aspirin: A survey of 1000 US adults aged 40-65

Objective: The Translating Research into Action (TRIA) study was initiated to gather dissemination information on emerging cancer control recommendations. Daily, low-dose aspirin has been identified as a promising means of preventing colorectal cancer, and stakeholders are already calling for research to facilitate dissemination. Thus, the current study sought to identify factors related to intention to use aspirin for colorectal cancer prevention. Methods: In April 2014, U.S. adults aged 40-65 (N = 1000) were recruited to participate in a survey grounded in the health belief model. Results: Older, Black males were more likely to intend to use low-dose aspirin to prevent colorectal cancer. Smokers, and those with a history of polyps, were also more receptive to initiating daily, low-dose aspirin use. Five psychosocial factors were related to intention including self-efficacy, response efficacy, perceived barriers, perceived susceptibility to colorectal cancer, and cancer information overload. Conclusion: Initial campaigns/interventions designed to increase daily, low-dose aspirin for colorectal cancer prevention may be more effective if they target receptive populations (older, Black males) using messages informed by the health belief model.
