Dietitians' perceptions about and personal nutrition practices for cancer risk reduction.
This study was undertaken to examine the beliefs and practices of dietitians in relation to cancer risk reduction through nutrition. Respondents to the national survey (N = 384, 70 percent) were similar in demographic, educational, and professional characteristics to the American Dietetic Association census data. They reported a strong preventive health orientation: mean performance on 10 preventive health behaviors was 77.5 on a 100 point scale. Half (53 percent) believed cancer would be serious if they developed it, 47 percent believed it was not likely that they would. About 20 percent of the respondents felt that the role of nutrition in cancer etiology was unclear. Dietitians believed strong research support existed for increasing whole grains, fruits and vegetables, and fiber to reduce cancer risk but that little evidence supported use of dietary supplements. Dietitians regularly practiced 75 percent of nutrition recommendations they believed to be effective in reducing cancer risk. Beliefs about the effectiveness of a recommendation accounted for the largest percentage of variance on nutritional practices. While dietitians reported many preventive health practices, including following nutrition recommendations, they seemed to be doing so for reasons other than preventing cancer.
