癌症幸存者患继发性癌症和其他疾病的风险增加。健康的饮食习惯可能会改善癌症幸存者的健康和wellbeing.Objective新鲜开始干预的持久性的影响，一个程序的顺序定制的邮寄材料，和标准化的邮寄材料（对照）癌症幸存者的饮食结果进行了评估超过2年的时间。预计FRESH START参与者的饮食收益会比对照组更大。设计参与者随机接受定制与标准化的10个月邮寄印刷干预措施，促进饮食和运动行为。数据收集在基线和1年和2年followups.Participants/setting乳腺癌和前列腺癌幸存者（n=543）被招募来自北美39个州和两个省。共有489名参与者完成了2年随访评估干预参与者被随机分配到一个为期10个月的定制邮寄印刷材料计划中，该计划旨在促进水果和蔬菜的消费，减少总脂肪和饱和脂肪的摄入，和/或增加运动量，或10个月的公开邮寄饮食和运动材料计划。（血液生物标志物支持）评估基线和1年和2年随访时的饮食习惯。进行配对样本t检验进行统计分析，以检查每个研究组内干预对饮食结果影响的持久性。然后用一般线性模型检验随访结果的组间差异，结果两组患者在第2年均报告饱和脂肪摄入量减少，水果和蔬菜摄入量增加，总体饮食质量较基线改善。然而，新鲜开始参与者报告更好的整体饮食质量和较低的总脂肪和饱和脂肪的摄入量相比，控制在2年follow-up.Conclusions结果表明，邮寄材料的干预措施，特别是那些量身定制的，可以产生。癌症幸存者的长期饮食改善。美国饮食协会杂志2011;111：1844-1851。
Background Cancer survivors are at increased risk for secondary cancers and other diseases. Healthy dietary practices may improve cancer survivors' health and wellbeing.Objective The durability of the effects of the FRESH START intervention, a program of sequentially tailored mailed materials, and standardized mailed materials (for controls) on cancer survivors' dietary outcomes was assessed over a 2-year period. Greater dietary gains were expected for FRESH START participants relative to controls.Design Participants were randomized to receive tailored vs standardized 10-month mailed print interventions promoting diet and exercise behaviors. Data were collected at baseline and 1- and 2-year follow-ups.Participants/setting Breast and prostate cancer survivors (n=543) were recruited from 39 states and two provinces within North America. A total of 489 participants completed the 2-year follow-up assessment (10% attrition).Intervention Participants were randomly assigned to either a 10-month program of tailored mailed print materials promoting fruit and vegetable consumption, reduced total and saturated fat intake, and/or increased exercise or to a 10-month program of publicly available mailed materials on diet and exercise.Main outcome measures Telephone surveys (supported with blood biomarkers) assessed dietary habits at baseline and 1- and 2-year follow-ups.Statistical analyses performed Paired-samples t tests were conducted to examine the durability of the intervention's effects on dietary outcomes within each study arm. Arm differences in follow-up outcomes were then tested with the general linear model, controlling for the baseline value of the outcomes.Results Both arms reported decreased saturated fat intake, increased servings of fruits and vegetables, and better overall diet quality at year 2 relative to baseline. However, FRESH START participants reported better overall diet quality and lower total and saturated fat intake compared to controls at the 2-year follow-up.Conclusions Results suggest that mailed material interventions, especially those that are tailored, can produce. long-term dietary improvement among cancer survivors.
