项目摘要

DESCRIPTION (provided by applicant): In support of NIH goals to improve people's health and support a healthy lifestyle, we will conduct a randomized trial to evaluate an age-targeted web-based intervention designed to improve the diet of a young adults (ages 21-30) as they navigate a new life stage of greater independence. The goal of our study is to increase daily intake of fruits and vegetables (FV) for young adults born in or after 1980, known as "Generation Y" (GenY), using relevant features that appeal to this group. This five-year project has two phases. In the first phase, we will use focus groups to confirm planned, key intervention elements that target needs and preferences of GenY and will build engagement in the intervention, as we revise our tested, effective Internet- based intervention (Making Effective Nutrition Choices or MENU, U19-CA079689). The MENU study was designed to support an increase in FV intake, and relied solely on e-media (internet and email). In the proposed study we will revise the MENU curriculum, applying age-targeted and theory-based methods to improve intervention engagement and effectiveness for GenY dietary behavior change. The intervention will use three psychosocial features which have been subject to empirical examination by age group: Social Cognitive Theory, Self-Determination Theory (SDT), with special attention to Social Marketing Theory (SMT), which emphasizes understanding the total environment to better shape health communications. In developing our program, we will apply knowledge about GenY from developmental psychology, guided by our consultants and formative research on individual, environmental and societal factors collected in our preliminary studies and Phase I GenY focus groups. Focus group members will evaluate our validated MENU intervention, as well as our revised age-targeted, interactive "MENU GenY" intervention prior to launch. In the second phase, we will evaluate the efficacy of the MENU GenY interventions, including the added value of the self-initiated, personalized e-coaching support by email, as a supplement to the tailored online intervention. Specifically, using a sample of 1624 adults, ages 21 - 30 and from two geographically distinct regions (urban Detroit and rural Pennsylvania), and employing a randomized, three arm design, the primary aims of Phase II are to 1) determine if an age-targeted, tailored web-based intervention is more efficacious in improving daily intake of FV compared to an untailored intervention arm with no age targeting (control arm); 2) determine if a tailored web-based intervention with age targeting and personalized e-coaching support is more efficacious than the control; and 3) determine if the tailored web-based intervention with age targeting and e-counseling is more efficacious than a tailored web-based intervention with age targeting alone. PUBLIC HEALTH RELEVANCE: As growing evidence points to increased health risks due to lifestyle choices and unhealthy eating, young adults are facing a declining life expectancy unless changes are made. The MENU Gen Y study will investigate and evaluate ways to engage and support improved dietary choices for young adults, who, at ages 21 through 30, are navigating a more independent life stage. Should our intervention be successful, our aims to use new communication media and evaluate an age-targeted online dietary behavioral change program will provide the opportunity to share essential strategies to reach this under-studied and vulnerable population, help reduce disease risk, and ultimately build lasting healthy dietary habits to help the next generation - their children.

描述（由申请人提供）：为了支持NIH的目标以改善人们的健康并支持健康的生活方式，我们将进行一项随机试验，以评估旨在改善年轻人饮食的基于年龄的基于年龄的基于网络的干预措施（21岁年龄段） -30）当他们在更大的独立性的新生活阶段导航时。我们研究的目的是使用吸引该组的相关特征来增加1980年或之后出生的年轻人的每日摄入水果和蔬菜（FV）。这个五年的项目有两个阶段。在第一阶段，我们将使用焦点小组确认计划的关键干预要素，这些要素针对基因的需求和偏好，并将在修改经过测试的，有效的基于Internet的干预措施（做出有效的营养选择或菜单）时建立干预中的参与度，U19-CA079689）。菜单研究旨在支持FV摄入量的增加，仅依赖于电子媒体（互联网和电子邮件）。在拟议的研究中，我们将修改菜单课程，采用以年龄为目标和基于理论的方法来改善基因饮食行为变化的干预参与和有效性。该干预将使用三个心理社会特征，这些特征是按年龄组按实证考试进行的：社会认知理论，自决理论（SDT），并特别关注社会营销理论（SMT），强调理解整体环境以更好地形成形状健康通信。在制定我们的计划时，我们将在我们的初步研究和I期基因焦点小组中收集的个人，环境和社会因素的顾问和形成性研究的指导下，以对发展心理学的基因进行了解。焦点小组成员将评估我们经过验证的菜单干预措施，以及我们在启动前经过修改的互动式“菜单基因”干预措施。在第二阶段，我们将评估菜单基因干预措施的功效，包括通过电子邮件通过电子邮件提供的自发，个性化的电子教练支持的附加值，作为对量身定制的在线干预的补充。具体而言，使用21-30岁的1624名成年人以及两个地理上不同的区域（城市底特律和宾夕法尼亚州农村），并采用随机的三个ARM设计，II期的主要目的是1）确定年龄是否与没有年龄靶向的未尾巴干预臂相比，受靶向的，量身定制的基于Web的干预措施可以改善每日FV的摄入量（控制臂）； 2）确定基于年龄定位的基于Web的量身定制干预措施和个性化的电子教练支持比控制更有效； 3）确定基于年龄定位的基于Web的量身定制干预是否比单独使用年龄定位的基于Web的干预更有效。公共卫生相关性：随着越来越多的证据指出，由于生活方式的选择和不健康的饮食，健康风险增加，除非发生变化，否则年轻人面临预期寿命的下降。菜单Gen Y研究将调查和评估如何参与和支持改善年轻人的饮食选择的方法，他们在21至30岁时正在浏览更独立的生活阶段。如果我们的干预成功，我们的目标是使用新的交流媒体并评估以年龄为目标的在线饮食行为改变计划，将为分享基本策略以达到这种研究不足和脆弱的人群，帮助降低疾病风险，并最终建立疾病的风险持续健康的饮食习惯可以帮助下一代 - 他们的孩子。
