Individual Counseling and/or Computer-Based Counseling in Helping Healthy Women Adopt a Cancer Prevention Diet

Unspecified Adult Solid Tumor, Protocol Specific

unspecified adult solid tumor, protocol specific

RATIONALE: Eating a diet high in fruits and vegetables and low in fat may lower the risk of some types of cancer. Dietary counseling may be effective in helping women change to a healthy diet. PURPOSE: This randomized clinical trial is studying how well individual counseling and/or computer-based counseling work in helping healthy women adopt a cancer prevention diet.

OBJECTIVES: * Compare 3-, 12-, and 18-month changes in self-reported daily servings of fruits and vegetables and percent of energy from fat in healthy women undergoing dietary modification intervention comprising in-person individualized counseling vs automated computer-based counseling vs both dietary modification interventions vs automated computer-based physical activity counseling (control). * Compare the efficacy and long-term effects of these interventions in these participants. * Compare participant acceptance of these interventions, in terms of the proportion and characteristics (e.g., age and race) of participants who accept the intervention and participate in intervention activities. * Compare initial dietary change, in terms of dietary habits, socio-demographics, and self-efficacy, in participants undergoing these interventions. * Compare the maintenance of dietary change, in terms of demographics, self efficacy, and perceived community environmental support, in participants undergoing these interventions. * Compare the cost of delivering these interventions to these participants. * Compare the cost of these interventions when used in routine practice. OUTLINE: This is a randomized study. Participants are randomized to 1 of 4 arms. * Arm I (in-person individualized dietary modification counseling): Participants undergo in-person individualized counseling in weeks 0 and 3 and receive a phone call by a counselor in weeks 1, 6, and 9 about increasing daily fruit and vegetable intake to 5-9 servings and reducing fat intake to no more than 25% of energy. * Arm II (automated computer-based dietary modification counseling): Participants undergo automated computer-based counseling in weeks 0 and 3 and receive an automated phone call in weeks 1, 6, and 9 about increasing daily fruit and vegetable intake to 5-9 servings and reducing fat intake to no more than 25% of energy. * Arm III (in-person individualized and automated computer-based dietary modification counseling): Participants undergo in-person individualized counseling and automated computer-based counseling in weeks 0 and 3 and receive a phone call by a counselor in week 6 and an automated phone call in weeks 1 and 9 about increasing daily fruit and vegetable intake to 5-9 servings and reduce fat intake to no more than 25% of energy. * Arm IV (automated computer-based physical activity counseling \[control\]): Participants undergo automated computer-based counseling in weeks 0 and 3 and receive an automated phone call in weeks 1, 6, and 9 about increasing daily physical activity to a moderate amount (20-30 minutes per day). After study completion, patients are followed at 3, 12, and 18 months. PROJECTED ACCRUAL: A total of 600 participants (150 per arm) will be accrued for this study within 2 years.
