目的：评估基于理论的定制化网络干预的有效性（年轻人饮食和积极健康）开发使用社区为基础的参与性研究过程。（10周强化干预，12个月随访）通过互联网和电子邮件进行随机对照试验。设置：13所大学校园。参与者：共1，639名大学生。干预：21个迷你教育课程和电子邮件（称为轻推）与非饮食方法一起开发，专注于饮食行为，体育活动，压力管理和健康体重管理。轻推是短的，频繁的，娱乐性的，并为每一种行为量身定制，并加强了课程内容。（自基线起3个月）和随访（自基线起15个月），用于体重、体重指数（BMI）、水果和蔬菜摄入量（FVI）、体力活动（PA）和感知压力的主要结局;次要结果包括腰围、膳食脂肪百分比、含糖饮料的能量、全谷类食物的摄入量、进餐时间行为的自我指导和调节、睡眠时间、以及对于食用5杯FVI、每周完成150分钟PA和在一周的大部分时间管理压力的变化的准备阶段。在baseline.Analysis：卡方分析和混合模型重复测量分析进行，以确定实验和对照outcome.Results之间的差异：实验和对照参与者的BMI，体重和腰围之间没有差异。在干预后，FVI（P = .001）、女性剧烈PA（P = .05）、脂肪摄入（P = .002）、自我指导（P = .001）、进餐时间行为调节（P = .004）和睡眠时间（P = .05）有小幅改善，但在随访时没有保持改善。在postintervention，更大比例的实验参与者的行动/维护阶段FVI（P = .019）和PA（P = .002）than control.Conclusions and Implications：年轻人的饮食和积极的健康是第一个研究使用社区为基础的参与性研究过程的PRECEDE-PROCEED开发一个非饮食方法干预。虽然实验组和对照组参与者在体重变化或BMI方面没有差异，但干预支持可能介导过度体重增加的行为的积极变化，例如增加FVI和更健康的自我调节进餐行为。需要探索维持行为变化的其他策略。
Objective: To assess the effectiveness of a tailored theory-based, Web-delivered intervention (Young Adults Eating and Active for Health) developed using community-based participatory research process.Design: A 15-month (10-week intensive intervention with a 12-month follow-up) randomized, controlled trial delivered via Internet and e-mail.Setting: Thirteen college campuses.Participants: A total of 1,639 college students.Intervention: Twenty-onemini-educational lessons and e-mailmessages (called nudges) developed with the non-diet approach and focusing on eating behavior, physical activity, stress management, and healthy weight management. Nudges were short, frequent, entertaining, and stage-tailored to each behavior, and reinforced lesson content.Main Outcome Measure: All participants were assessed at baseline, postintervention (3 months from baseline), and follow-up (15 months from baseline) for primary outcomes of weight, body mass index (BMI), fruit and vegetable intake (FVI), physical activity (PA), and perceived stress; and secondary outcomes of waist circumference, percent dietary fat, energy from sugar-sweetened beverages, servings of whole grains, self-instruction and regulation for mealtime behavior, hours of sleep, and stage of readiness for change for consuming 5 cups of FVI, completing 150 minutes of PA/wk, and managing stress on most days of the week. Demographics were collected at baseline.Analysis: Chi-square analysis and mixed-models repeated measures analysis were performed to determine differences between experimental and control outcomes.Results: There were no differences between experimental and control participants in BMI, weight, and waist circumference. There were small improvements in FVI (P = .001), vigorous PA in females (P = .05), fat intake (P = .002), self-instruction (P = .001), and regulation (P = .004) for mealtime behavior, and hours of sleep (P = .05) at postintervention, but improvements were not maintained at follow-up. At postintervention, a greater proportion of experimental participants were in the action/maintenance stages for FVI (P = .019) and PA (P = .002) than control.Conclusions and Implications: Young Adults Eating and Active for Health is one of the first studies to use the community-based participatory research process of PRECEDE-PROCEED to develop a non-diet approach intervention. Although there were no differences between experimental and control participants in weight change or BMI, the intervention supported positive change in behaviors that may mediate excessive weight gain, such as increasing FVI and more healthful self-regulation mealtime behaviors immediately postintervention. Additional strategies to maintain the behavior changes need to be explored.
