DESCRIPTION (provided by applicant): Poor quality diet and physical inactivity are the most prevalent, preventable causes of death in the United States. In particular, high saturated fat diet (Fat), low fruit and vegetable intake (FV), low physical activity (PA), and high sedentary leisure screen time (Sed) co-occur and heighten the risks of cardiovascular disease and cancers. The first Make Better Choices (MBC1) experiment contrasted four strategies to promote healthful change across these four risk behaviors. Each intervention targeted two behaviors (one diet, one activity) simultaneously and either increased healthy or decreased unhealthy responding. The intervention targeting increased FV and decreased Sed was most efficacious, yielding unexpectedly sustained improvement in three out of the four risk behaviors (FV, Sed, Fat). The proposed MBC2 trial tests the efficacy of MBC intervention to promote sustained, healthful change in diet and activity at 6 and 12 months, as contrasted with an attention control treatment (stress management) . MBC2 also (a) tests competing hypotheses about the optimal way to add PA without undermining maintenance of FV, Sed, and Fat; and (b) examines mediators and biomarkers of healthy lifestyle change. Community dwelling adults (N=250) with suboptimal diet and inactive lifestyle will be randomized to: 1) Sequential MBC (FV+ Sed-, followed by PA+), 2) Simultaneous MBC (FV+Sed-PA+), or 3) Control (stress management). All will use a smart phone with behavioral decision support tools to self- monitor and transmit data and will be coached by telephone. The Mastery hypothesis, based upon theories of self-regulatory strength and habit, predicts superior healthy change for sequential intervention, mediated by greater habit strength for healthy eating and activity. The Synergy hypothesis, based upon goal systems theory, predicts best outcome from simultaneous intervention, mediated by the establishment of a superordinate healthy lifestyle goal. Results of the MBC2 trial will shed light on mechanisms that underlie healthy change in prevalent risk behaviors. If successful, the trial also will result in an innovative, highly disseminable technology-supported minimal counseling intervention to address the modal American unhealthy diet and sedentary lifestyle.

描述（由申请人提供）：不良饮食和缺乏身体活动是美国最普遍、可预防的死亡原因。特别是，高饱和脂肪饮食（Fat）、低水果和蔬菜摄入量（FV）、低体力活动（PA）和高久坐休闲屏幕时间（Sed）同时发生，会增加心血管疾病和癌症的风险。第一个做出更好的选择 (MBC1) 实验对比了四种策略，以促进这四种风险行为的健康改变。每项干预措施同时针对两种行为（一种饮食，一种活动），要么增加健康反应，要么减少不健康反应。针对增加 FV 和减少 Sed 的干预措施最为有效，四种风险行为中的三种（FV、Sed、Fat）出人意料地持续改善。拟议的 MBC2 试验测试了 MBC 干预在 6 个月和 12 个月时促进饮食和活动持续、健康改变的功效，与注意力控制治疗（压力管理）相比。 MBC2 还 (a) 测试有关在不破坏 FV、Sed 和 Fat 维持的情况下添加 PA 的最佳方式的相互竞争的假设； (b) 检查健康生活方式改变的中介因素和生物标志物。饮食不理想且生活方式不活跃的社区居民成年人 (N=250) 将被随机分配至：1) 顺序 MBC（FV+ Sed-，然后是 PA+），2) 同时 MBC (FV+Sed-PA+)，或 3) 控制（压力管理）。所有人都将使用带有行为决策支持工具的智能手机来自我监控和传输数据，并通过电话进行指导。基于自我调节强度和习惯理论的掌握假说预测，通过健康饮食和活动的更大习惯强度介导的连续干预将带来更好的健康变化。协同假说基于目标系统理论，预测同步干预的最佳结果，并通过建立最高的健康生活方式目标来介导。 MBC2 试验的结果将揭示普遍风险行为健康改变的机制。如果成功，该试验还将产生一种创新的、高度传播的技术支持的最低限度的咨询干预措施，以解决美国人不健康的饮食和久坐的生活方式。
