Randomized trial of a low-intensity dietary intervention in rural residents: the Rural Physician Cancer Prevention Project.
BACKGROUND
Dietary behavior, specifically a low-fat, high-fiber diet, plays a role in the primary prevention of chronic diseases including cancer.


METHODS
A community-based randomized trial to assess the impact of a low-intensity, physician-endorsed, self-help dietary intervention that provided tailored dietary feedback, and was designed to promote improved fat and fiber behavior in a rural, low-education/low-literacy, partly minority population. The data were collected from 1999 to 2003.


METHODS
A total of 754 patients from three physician practices in rural Virginia completed a baseline telephone survey assessing dietary and psychosocial information, and were then randomly assigned to the intervention or control condition. Follow-up telephone evaluation was based on 522 participants at 1 month, 470 at 6 months, and 516 participants at 12 months.


METHODS
A series of tailored feedback, followed by brief telephone counseling and theory-based nutritional education booklets, provided by staggered delivery to the home.


METHODS
Dietary fat and fiber behavior, dietary intentions to change, self-efficacy for dietary change, and fat and fiber knowledge.


RESULTS
The intervention group demonstrated significant improvement in dietary fat and fiber behaviors and intentions to change fat and fiber intake (p <0.05) at 1, 6, and 12 months.


CONCLUSIONS
The Rural Physician Cancer Prevention Project provides an effective model for achieving public health-level dietary health behavior changes among a rural, minority, and low-literacy/low-education population.
