项目摘要

Abstract Men in the United States have an exceptionally high prevalence of overweight and obesity, i.e., 71.3%, and 42% of men are currently attempting weight loss. However, men are dramatically underrepresented in weight loss programs. Men find conventional weight loss program (i.e., group-based, education and counseling- orientated, dietary/calorie-focused) unappealing because they involve receiving counseling, focus on replacing “masculine” foods (e.g., meat) with “feminine” ones (e.g., salad), and provide minimal personalization or autonomy. As such, attempts have been made to increase recruitment and appeal through targeted recruitment and adaptations to standard weight loss programs. However, these efforts have been disappointing. Mobile applications (mHealth apps) have attractive features, but have low male enrollment and poor efficacy as conventionally delivered. A gamified mHealth program offers the possibility of engaging men and enhancing efficacy given that (1) video gaming is highly appealing to men; (2) gamification features (e.g., digital rewards for attaining “streaks” and milestones, competition) are known enhance enjoyment and motivation and facilitate desired behaviors; and (3) “neurotraining” video games featuring repetitive action mechanics, adaptive difficulty, and feedback can train inhibitory control, a basic brain capacity to inhibit intrinsically-generated approach responses that is strongly linked to body mass and the consumption of high- calorie foods. Inhibitory control training (ICT) games have been successful at reducing consumption of targeted foods/beverages and improving short-term weight loss. For instance, in our preliminary work we demonstrated that a weight loss workshop plus a short, daily ICT produced greater weight loss for individuals with higher- than-average implicit preferences for high-sugar foods, compared to a robust attention control (i.e., the workshop plus a sham training), and we found that adding gamification elements (e.g., story, music, levels) to a rudimentary game produced additional 8-week weight loss for men (4.1% vs 2.5%). This project extends previous work by evaluating the independent effects of gamification and ICT on long-term engagement and outcomes. As such, 243 men with BMI ≥ 25 will be recruited, with 15 participating in usability testing and 228 assigned to a 12-month mHealth weight loss program that prescribes digital self-monitoring and dietary and physical activity targets. Utilizing an efficient 2 x 2 factorial design, participants will be randomized to receive either a standard or fully-gamified program, comprised of a behavior change program featuring team-based competition, and digital reinforcers for attainment of streaks and milestones, and also randomized to receive either sham or active inhibitory control neurotraining. Aims include evaluating the efficacy of gamification and ICTon weight loss, diet and physical activity at 12 months, as well as evaluating hypothesized mediators (engagement and inhibitory control) and moderators (baseline frequency of video game play and implicit preferences for ICT-targeted foods).

抽象的美国男性超重和肥胖的患病率异常高，即 71.3%， 42% 的男性目前正在尝试减肥。然而，男性在体重方面的代表性严重不足损失计划。男性发现传统的减肥计划（即基于团体的、教育和咨询- 以饮食/卡路里为导向）没有吸引力，因为它们涉及接受咨询，专注于替代 “男性化”食物（例如肉类）与“女性化”食物（例如沙拉），并提供最低限度的个性化或自治。因此，已尝试通过有针对性的方式增加招募和吸引力标准减肥计划的招募和调整。然而，这些努力已经令人失望。移动应用程序（移动医疗应用程序）具有吸引人的功能，但男性入学率较低，而且传统治疗效果不佳。游戏化移动医疗计划提供了吸引男性参与的可能性并提高效率，因为 (1) 电子游戏对男性极具吸引力； (2) 游戏化特征（例如，众所周知，获得“连胜”和里程碑、竞争的数字奖励可以增强乐趣和动机并促进期望的行为； (3) 具有重复动作的“神经训练”视频游戏力学、适应性难度和反馈可以训练抑制控制，这是一种基本的大脑抑制能力内在产生的接近反应与体重和高能量消耗密切相关卡路里食物。抑制控制训练 (ICT) 游戏已成功减少目标物质的消耗食品/饮料和改善短期减肥。例如，在我们的前期工作中，我们证明了减肥研讨会加上简短的每日信息通信技术可以为体重较高的个人带来更大的减肥效果与强大的注意力控制相比，对高糖食物的隐性偏好高于平均水平（即研讨会加假训练），我们发现添加游戏化元素（例如故事、音乐、关卡）一项简单的游戏使男性在 8 周内额外减轻了体重（4.1% vs 2.5%）。该项目延伸之前的工作通过评估游戏化和信息通信技术对长期参与的独立影响和结果。因此，将招募 243 名 BMI ≥ 25 的男性，其中 15 名参加可用性测试，228 名参加可用性测试。被分配参加为期 12 个月的移动健康减肥计划，该计划规定数字自我监测和饮食习惯身体活动目标。利用高效的 2 x 2 因子设计，参与者将被随机分配接受标准或完全游戏化的计划，由基于团队的行为改变计划组成竞争，以及数字强化物以实现连胜和里程碑，并随机接受假手术或主动抑制控制神经训练。目的包括评估游戏化的功效和 ICTon 12 个月时的体重减轻、饮食和身体活动，以及评估假设的中介因素（参与和抑制控制）和调节者（视频游戏玩的基线频率和隐含的对 ICT 食品的偏好）。
