Behavioral weight loss interventions promote clinically significant weight loss over 12 months, but weight regain remains problematic and a substantial proportion of participants do not achieve long-term weight loss maintenance. Novel methods are needed that instill habit strength for sustaining weight control behaviors long term. Virtual reality (VR) has the potential to provide opportunities within behavioral treatment for patients to practice desired weight control behaviors in the frequency and magnitude necessary to build durable habits. A pilot randomized trial was done to test the feasibility integrating virtual reality (VR) into standard behavioral weight loss treatment. Participants were 15 adults (43 years; 46.7% Hispanic), with overweight or obesity who were randomly assigned to a 4-week Standard Behavioral Weight Loss plus Non-Weight-Related VR app (i.e., Control Group) or Standard Behavioral Weight Loss plus Weight-Related VR app (i.e., Intervention Group). The Intervention’s VR tool was designed to enable practice of behavioral skills taught in weekly group meetings, including managing social and home environmental cues for eating and activity. Participants were recruited over 3 months, and retention at the final assessment visit was high (86.6%). The VR footage and resulting app were rated as highly realistic (6.7 on a 10-point scale), and the VR program overall was rated as highly satisfactory (3.6 on a 4-point scale). Adverse effects of eye strain and motion sickness were minimal (~ 2 on a 7-point scale). As expected, the intervention and control groups both lost weight and unadjusted means (SD) averaged 3.4% (2.7) and 2.3% (3.6), respectively, over the 4 weeks. Overall, participants reported preferring a VR approach above traditional weight loss programs (rating of 5 on a 7-point scale). Future research is needed to develop and test the feasibility of using VR for other weight control skills with a larger sample size and longer evaluation period to determine if VR can improve standard behavioral weight loss outcomes by intensifying practice opportunities and building habit strength for weight loss maintenance.

基于虚拟现实的方法改善行为体重管理结果的可行性

行为减肥干预在 12 个月内促进了临床上显着的体重减轻,但体重反弹仍然存在问题,相当大比例的参与者没有实现长期减肥维持。需要新的方法来灌输习惯强度以长期维持体重控制行为。虚拟现实 (VR) 有可能在行为治疗中为患者提供机会,以建立持久习惯所需的频率和幅度练习所需的体重控制行为。进行了一项试点随机试验,以测试将虚拟现实 (VR) 集成到标准行为减肥治疗中的可行性。参与者是 15 名成年人(43 岁;46.7% 西班牙裔),超重或肥胖的人被随机分配到 4 周标准行为减肥加非体重相关 VR 应用程序(即对照组)或标准行为减肥加体重相关 VR 应用程序(即干预组)。The Intervention 的 VR 工具旨在实现每周小组会议中教授的行为技能的实践,包括管理饮食和活动的社会和家庭环境线索。参与者的招募时间超过 3 个月,最终评估访问时的保留率很高 (86.6%)。VR 镜头和由此产生的应用程序被评为高度逼真(10 分制 6.7),VR 程序整体被评为非常满意(4 分制 3.6)。眼睛疲劳和晕动病的不良影响很小(7 分制为 2 分)。正如预期的那样,在 4 周内,干预组和对照组的体重减轻和未调整均值 (SD) 平均分别为 3.4% (2.7) 和 2.3% (3.6)。总体而言,参与者报告更喜欢 VR 方法而不是传统的减肥计划(7 分制评分为 5)。未来的研究需要以更大的样本量和更长的评估周期来开发和测试将 VR 用于其他体重控制技能的可行性,以确定 VR 是否可以通过增加练习机会和建立维持减肥的习惯强度来改善标准行为减肥结果.
