Individual Counseling and/or Computer-Based Counseling in Helping Healthy Women Adopt a Cancer Prevention Diet
16 février 2017 mis à jour par: Kaiser Permanente
Helping Women Adopt a Cancer Prevention Diet
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.

Description détaillée
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.

Armes et Interventions
Groupe de participants / Bras |
Intervention / Traitement |
|---|---|
|
Expérimental: Computer Only
Dietary Counseling delivered by interactive computer program, without the addition of individual counseling provided by a health counselor.
This arm tested a completely automated counseling program that did not include personalized behavioral counseling provided by a study staff member.
|
An interactive computer program that addresses dietary change, barriers to change and possible solution to barriers to develop an action plan
|
|
Expérimental: Counseling only
In this arm, dietary counseling was delivered by nutritionist, and this counseling did not include use of an automated, computer program.
|
A one on one counseling sessions to addresses dietary change, barriers to change and possible solution to barriers to develop an action plan
|
|
Expérimental: Combined
In this arm, participants received dietary counseling delivered using both the automated computer program and additional counseling by a study nutritionist.
That is, this arm combined the intervention programs delivered in the other two active intervention arms.
|
An interactive computer program plus one on one nutrition counseling that addresses dietary change, barriers to change and possible solution to barriers to develop an action plan
|
|
Comparateur actif: Physical Activity-computer
Participants assigned to this arm did not receive nutrition counseling, but they were provided physical activity counseling delivered by computer only.
|
An interactive computer program that addresses increase to physical activity, barriers to change and possible solution to barriers to develop an action plan
