Achieving substantial changes in eating behavior among women previously treated for breast cancer--an overview of the intervention.
OBJECTIVE
To describe the intervention in a clinical trial examining the effect of a plant-based diet on breast cancer recurrence. To report baseline to 12-month dietary change and investigate whether cooking-class attendance influenced adherence to the study's dietary targets.


METHODS
A descriptive analysis of baseline and 12-month dietary intake data and other variables from a subcohort of participants in the Women's Healthy Eating and Living Study.


METHODS
Seven hundred thirty-nine women (primarily non-Hispanic white and well educated) who had been treated for early stage breast cancer. All were intervention group participants and had adhered to the Women's Healthy Eating and Living Study counseling and dietary assessment protocols. Mean age at study entry was 54 years, and mean body mass index was 26.7.


METHODS
Telephone counseling, complemented by an orientation meeting, cooking classes, and newsletters.


METHODS
The change in intake of vegetables, vegetable juice, fruit, fiber, and fat between baseline and 12 months is reported, and the association between cooking classes attended and overall dietary adherence is examined.


METHODS
Mean intake for vegetables, vegetable juice, fruit, fiber, and fat were calculated. Percentage of women meeting select Healthy People 2010 objectives were tabulated.


RESULTS
Total daily vegetable, vegetable juice, fruit, and fiber intake increased significantly (P <.01), while fat decreased significantly (P <.01). The percentage of women meeting the Healthy People 2010 fruit and vegetable objectives increased substantially. Overall dietary adherence was associated with increased cooking-class attendance (P for trend <.01).


CONCLUSIONS
A multimodal approach to dietary modification, based largely on individualized telephone counseling, can substantially change the overall dietary pattern of women previously treated for breast cancer.
