需要帮助成年人改善饮食质量以降低癌症风险的预防计划。这项IIa期研究前瞻性地测试了一种移动健康干预措施，旨在提高对癌症预防饮食质量指南的依从性。所有参与者（N = 62）接受营养教育和自我调节技能课程，主要目标是改变杂货店购物行为。使用随机析因设计，研究改变了是否将以下4个组件中的每一个添加到20周的干预中：（1）位置触发的应用程序消息，当个人到达杂货店时传递，（2）对变化的好处的思考，通过额外的辅导时间和定制的应用程序消息传递，（3）教练监控，其中食品购买由教练数字监控，（4）家庭成员参与干预。成功达到招募、保留和治疗可接受性的基准。在各种条件下，从治疗前到治疗后，高度加工食品摄入量（P <0.001，η2 = 0.48），红肉和加工肉类摄入量（P <0.001，η2 = 0.20）以及含糖饮料摄入量（P = 0.008，η2 = 0.13）显著减少。分析每个干预成分是否影响随时间的变化，发现接受教练监测的参与者增加了水果，蔬菜和纤维的摄入量，而没有教练监测的参与者改善较少（P = 0.01，η2 = 0.14）。在家庭支持ON的参与者中，红肉和加工肉的改善程度高于家庭支持OFF的参与者，处于轻微显著水平（P = .056，η2 = .07）。这项研究表明，可行性，可接受性和初步信号的有效性，远程交付的干预措施，以促进遵守饮食指南预防癌症和教练监测和家庭支持可能是特别有效的战略。一个完全有效的临床试验是必要的，以测试干预的优化版本，包括营养教育，自我调节技能培训，教练监测和家庭成员的参与。ClinicalTrials.gov NCT04947150。
Prevention programs that can help adults improve the quality of their diets to reduce cancer risk are needed. This Phase IIa study prospectively tested a mHealth intervention designed to improve adherence to dietary quality guidelines for cancer prevention. All participants (N = 62) received nutrition education and a self-regulation skills curriculum, with a primary target of changing grocery shopping behavior. Using a randomized, factorial design, the study varied whether each of the following 4 components were added to the 20-week intervention: (1) location-triggered app messaging, delivered when individuals arrived at grocery stores, (2) reflections on benefits of change, delivered with extra coaching time and tailored app messages, (3) coach monitoring, in which food purchases were digitally monitored by a coach, and (4) involvement of a household member in the intervention. Benchmarks were successfully met for recruitment, retention, and treatment acceptability. Across conditions, there were significant reductions in highly processed food intake (P < .001, η2 = .48), red and processed meat intake (P < .001, η2 = .20), and sugar-sweetened beverage intake (P = .008, η2 = .13) from pre-to post-treatment. Analyses examining whether each intervention component influenced change across time found that participants who received coach monitoring increased their intake of fruits, vegetables, and fiber, whereas those with no coach monitoring had less improvement (P = .01, η2 = .14). The improvement in red and processed meat was stronger among participants with household support ON, at a marginally significant level, than those with household support OFF (P = .056, η2 = .07). This study showed feasibility, acceptability, and preliminary signals of efficacy of a remotely delivered intervention to facilitate adherence to dietary guidelines for cancer prevention and that coach monitoring and household support may be especially effective strategies. A fully powered clinical trial is warranted to test an optimized version of the intervention that includes nutrition education, self-regulation skills training, coach monitoring, and household member involvement.
