Clinically significant weight loss is defined as a ≥5% of initial body weight loss within a 6-month period. The purpose of this study was to assess body weight change from a 12-week telehealth-based weight loss program that integrated health coaching via video conferencing.
A total of 25 obese participants (12 males, 13 females) were recruited for this fully online 12-week weight loss program. Participants were randomly assigned to either an intervention group or control group ( n = 13 intervention, body mass index (BMI) = 34.7 ± 4.5 kg/m; n = 12 control, BMI = 34.4 ± 4.43 kg/m). All participants were given access to a secure platform for data tracking and video conferencing with the research team. The intervention group met with the medical doctor once per month and with a registered dietitian, weekly. Control participants met with the research team at baseline and at 12 weeks. Independent samples t-tests and Chi-square tests were used via SPSS version 24 with significance set to p < 0.05.
There was a significant difference between the intervention and control groups for body weight loss (7.3 ± 5.2 versus 1.2 ± 3.9 kg, respectively, p < 0.05) as well as for percent body weight loss (7.16 ± 4.4 versus 1.5 ± 4.1%, respectively, p < 0.05). Clinically significant weight loss was achieved in 9 out of 13 (69.2%) in the intervention group versus 1 out of 12 (8%) in the control group.
Mobile phone-based health coaching may promote weight loss. Weekly video conferencing with education may be an applicable tool for inducing significant body weight loss in obese individuals.
临床上显著的体重减轻定义为在 6 个月内体重初始值下降≥5%。本研究的目的是评估通过基于视频会议的健康教练整合的 12 周远程医疗减肥计划的体重变化。
共有 25 名肥胖参与者(男性 12 名,女性 13 名)被招募参加这个完全在线的 12 周减肥计划。参与者被随机分配到干预组或对照组(n=13 干预组,体重指数(BMI)=34.7±4.5kg/m;n=12 对照组,BMI=34.4±4.43kg/m)。所有参与者都可以访问一个安全的平台,用于数据跟踪和与研究团队的视频会议。干预组每月与医生会面一次,每周与注册营养师会面一次。对照组在基线和 12 周时与研究团队会面。使用 SPSS 版本 24 进行独立样本 t 检验和卡方检验,显著性水平设置为 p<0.05。
干预组和对照组的体重减轻量有显著差异(分别为 7.3±5.2kg 和 1.2±3.9kg,p<0.05),体重百分比减轻量也有显著差异(分别为 7.16±4.4%和 1.5±4.1%,p<0.05)。干预组中有 9 人(69.2%)达到了临床显著的体重减轻,而对照组中只有 1 人(8%)达到了这一目标。
基于手机的健康教练可能会促进体重减轻。每周通过视频会议进行教育可能是一种适用于诱导肥胖个体显著体重减轻的工具。
