In this pilot study, the effects of two computer-assisted dieting (CAD) interventions on weight loss and blood chemistry were examined among overweight and obese adults. Participants (91 community members, average age 42.6 years) were randomly assigned to CAD-only (a single-session introduction and provision of a dieting software, n = 30), CAD plus an additional four-session self-management group training (CAD+G, n = 31) and a waitlist control group whose members were randomised into the two interventions at the 3-month follow-up (n = 30). A three (group)-by-two (time) repeated measures ANOVA revealed no significant group by time interaction during the initial 3-month period. However, the two intervention groups combined showed a significant, though moderate weight loss relative to the control group. Further, although a general improvement was found with regard to the lipid panel results during the first 3 months of the trial, the treatment by time interaction was not significant. A comparison of the developments in the two intervention groups during the 3- to 6-month follow-up time period revealed a tendency towards greater weight regain in the CAD-only condition. The evidence suggests that CAD supports initial weight loss; however, additional self-management training might be necessary to support maintenance.
在这项初步研究中，我们考察了两种计算机辅助节食干预（CAD）对超重和肥胖成年人减肥和血液化学的影响。参与者（91 名社区成员，平均年龄 42.6 岁）被随机分配到仅 CAD 组（单次介绍和提供节食软件，n = 30）、CAD 加额外的四次自我管理团体培训（CAD+G，n = 31）和等候名单对照组，后者在 3 个月的随访中被随机分配到这两种干预措施（n = 30）。三次（组）×两次（时间）重复测量方差分析显示，在最初的 3 个月内，组间时间没有显著的相互作用。然而，与对照组相比，这两个干预组的结合显示出了显著的，尽管是中等程度的体重减轻。此外，尽管在试验的前 3 个月中，脂质面板结果普遍有所改善，但治疗时间的相互作用并不显著。对 3 至 6 个月随访期间两个干预组的发展进行比较，发现仅 CAD 组的体重恢复趋势更大。有证据表明，CAD 支持初始减肥；然而，可能需要额外的自我管理培训来支持维持。
