Obesity is an important public health concern with limited effective treatment options. Internet-based technologies offer a cost-effective means to treat obesity. However, most of the online programs have been of short duration, have focused on a limited number of treatment modalities, and have not utilized the potential of coaching as part of the intervention. In this paper, we present the design, methods and participants' baseline characteristics in a real-life internet-based weight management program. Healthy Weight Coaching (HWC) is a 12-month web-based intervention for the management of obesity. The program is based on the Acceptance and Commitment Therapy and includes themes important for weight loss, including diet, physical activity, psychological factors, and sleep. In addition to the automated, interactive program, a personal coach is allocated to each participant. The participants are nationally enrolled through referrals from primary care, occupational health, hospitals, and private health care units. Adult individuals with BMI ≥25 kg/m without severe complications are included. On a weekly basis, participants submit their weight logs, training sessions, and lifestyle targets to the internet portal and are scheduled to have online discussions with their coaches 26 times over the course of a year. Questionnaires on lifestyle, diet, physical activity, psychological factors, sleep, and quality of life are completed at baseline, 3, 6, 9, and 12 months, and thereafter yearly until 5 years. Additionally, log data on the use of the service and discussions with the coach are collected. The main outcome is weight change from baseline to 12 months. Recruitment to the HWC is ongoing. Baseline data of the participants recruited between Oct 2016 and Mar 2019 (n = 1189) are provided. This research will bring insight into how internet-based technologies can be implemented in the virtual management of obesity.
The trial is registered at clinicaltrials.cov (Clinical Trials Identifier NCT04019249).
肥胖是一个重要的公共卫生问题，有效的治疗选择有限。基于互联网的技术提供了一种经济有效的治疗肥胖的方法。然而，大多数在线项目持续时间较短，侧重于有限的几种治疗方式，并且没有将指导作为干预措施的一部分发挥其潜力。在本文中，我们介绍了一个基于互联网的现实生活中的体重管理项目的设计、方法和参与者的基线特征。健康体重指导（HWC）是一项为期12个月的基于网络的肥胖管理干预措施。该项目基于接受与承诺疗法，包括对减肥重要的主题，如饮食、体育活动、心理因素和睡眠。除了自动化的互动项目外，还为每位参与者分配了一名私人教练。参与者通过初级保健、职业健康、医院和私人医疗保健单位的推荐在全国范围内招募。纳入BMI≥25kg/m²且无严重并发症的成年个体。参与者每周向互联网门户网站提交他们的体重记录、训练课程和生活方式目标，并计划在一年中与他们的教练进行26次在线讨论。在基线、3个月、6个月、9个月和12个月时完成关于生活方式、饮食、体育活动、心理因素、睡眠和生活质量的问卷调查，此后每年进行一次，直至5年。此外，还收集关于服务使用情况和与教练讨论的日志数据。主要结果是从基线到12个月的体重变化。HWC的招募工作正在进行中。提供了2016年10月至2019年3月期间招募的参与者（n = 1189）的基线数据。这项研究将深入了解基于互联网的技术如何在肥胖症的虚拟管理中得到应用。
