OBJECTIVE: The aim of this study was to evaluate health behaviors among patients with colorectal cancer (CRC) and their at-risk relatives prior to undergoing genetic counseling and testing for Lynch syndrome and to examine associations between health risk behaviors and specific demographic and psychological variables. METHODS: Participants included patients with CRC (n = 319) and their cancer-unaffected relatives (n = 110) who were enrolled in studies regarding Lynch syndrome genetic testing. Prior to undergoing genetic counseling or testing, participants completed a questionnaire including measures of demographic characteristics, health behaviors, cancer screening practices (Pap test, clinical breast exam, and mammogram), and psychological distress. RESULTS: Unaffected participants scored higher on a risk behavior index (RBI) than patients with CRC (1.7 (SD = 1.0) vs. 1.4 (SD = .09); p < .01). All female participants underwent cancer screening at rates similar to national data. Higher RBI scores were associated with being male, having less education, and age less than 50-years. CONCLUSIONS: We identified several health behaviors for potential intervention, including smoking, alcohol use, and diet. Genetic counseling offers a promising avenue for education and risk behavior reduction in persons at increased risk for cancer due to a familial or genetic predisposition, and a teachable moment to introduce lifestyle modifications.
