健康的饮食模式，包括吃水果和蔬菜 (F&V) 以及避免肥胖，可以降低患癌症和其他慢性疾病的风险。除了促进普通人群的健康之外，癌症诊断还可以提供一个“教育时刻”，促进采用更健康的饮食习惯，降低慢性病风险并改善整体健康状况。本研究旨在测试两种健康沟通干预措施在增加老年人样本（平均年龄 66 岁）中的 F&V 消费和体力活动的有效性，其中包括结直肠癌 (CRC) 幸存者和非结直肠癌 (N-CRC) 个体。CRC 幸存者和N-CRC 个体是从基于人群的病例对照研究中招募的，并使用 2 x 2 设计随机分配到四种情况。我们单独或组合测试了两种不同的沟通和促进健康行为改变的方法：定制印刷沟通（TPC）和简短的基于电话的动机访谈（TMI）。发现整个样本中联合干预组的食品和饮料消费显着增加（p < 0.05）。当按癌症幸存者状态分层时，与 CRC 幸存者相比，效果集中在 N-CRC 子集 (p < 0.01) 中。还发现联合干预对于 N-CRC 组最具成本效益，其中 TPC 比 TMI 更具成本效益。对于身体活动，没有任何干预措施产生统计上显着的改善。这项研究表明，结合定制和动机访谈可能是促进老年健康成年人饮食行为改变的有效且具有成本效益的方法。需要更多的研究来确定干预策略的最佳剂量和时机，以促进结直肠癌幸存者和普通人群的饮食和身体活动改变。
Healthful dietary patterns, including eating fruits and vegetables (F&V) and avoiding obesity, may decrease the risk of cancer and other chronic diseases. In addition to promoting health for the general population, a cancer diagnosis may provide a "teachable moment," facilitating the adoption of more healthful eating habits and leading to lower risk of chronic disease and better overall health.This study was designed to test the effectiveness of two health communication interventions in increasing F&V consumption and physical activity in a sample of older adults (average age of 66 years), including both colorectal cancer (CRC) survivors and noncolorectal cancer-affected (N-CRC) individuals.CRC survivors and N-CRC individuals were recruited from a population-based case-control study and randomly assigned to four conditions using a 2 x 2 design. We tested two different methods of communicating and promoting health behavior change alone or in combination: tailored print communication (TPC) and brief telephone-based motivational interviewing (TMI).A significant increase in F&V consumption was found for the combined intervention group in the entire sample (p < 0.05). When stratified by cancer survivor status, the effect was concentrated in the N-CRC subset (p < 0.01) versus CRC survivors. The combined intervention was also found to be most cost-effective for the N-CRC group, with TPC more cost-effective than TMI. For physical activity, none of the interventions produced statistically significant improvements.This study indicates that combining tailoring and motivational interviewing may be an effective and cost-effective method for promoting dietary behavior change among older healthy adults. More research is needed to identify the optimal dose and timing for intervention strategies to promote dietary and physical activity change among both CRC survivors and the general population.
