9019 Background: A healthy diet and regular exercise may improve the health, well-being and ultimate survival of cancer survivors. Last year, results of the FRESH START trial (n=543) were presented at ASCO; significant improvements in diet and exercise behaviors of breast and prostate cancer survivors were observed with two 10-month mailed print interventions - one that was sequentially- tailored and another using non-tailored print materials in the public domain (attention control). While both arms achieved significant improvements, those receiving the tailored intervention reported significantly greater changes (all p-values <.05). The durability of these changes, however, is not known. Methods: At 2-year follow-up, and after a 12-month wash-out, telephone surveys that were conducted at baseline and post-intervention (Diet History Questionnaire and 7-Day Physical Activity Recall) were repeated. Results: Ordinary Least Square analysis suggest that changes from baseline largely remain significant at 2-year follow-up for both interventions (see table ). Moreover, significant differences between arms are observed for dietary fat restriction and the practice of more lifestyle behaviors at goal level [i.e., consumption of ≥ 5 servings/day of fruits & vegetables (F&V), < 30% kcal from fat, and >150 min/week of exercise], with the tailored intervention arm achieving levels superior to those achieved in the attention control arm. Conclusions: Tailored and untailored interventions delivered over a 10-month period to cancer survivors exert durable effects on several lifestyle behaviors. However, the effects of the tailored intervention were initially more powerful and largely sustained over time (especially, with regard dietary fat restriction). No significant financial relationships to disclose. [Table: see text]
