The purpose of this study was to compare the efficacy of two home-based weight loss interventions that differ only in the amount of outside support provided.
This was a 12-week, randomized, controlled trial. One group received limited support (LWS, n = 35) via a single 10 min phone call each week while another group received no weekly support (NWS, n = 28). Both the LWS and NWS received pre-packaged meals (PM) and shakes. A third group served as control (CON, n = 30) and received no components of the intervention. Weight loss at 12 weeks was the primary outcome. Diet (PM, shake, and fruit/vegetable (F/V) intake) and physical activity (PA) were self-monitored, recorded daily and reported weekly. An exit survey was completed by participants in the intervention groups upon completion of the study.
Weight loss and percent weight loss in the LWS, NWS, and CON groups were 7.7 ± 4.4 kg (8.5 ± 4.2%), 5.9 ± 4.1 kg (6.0 ± 4.2%), and 0.3 ± 1.9 kg (0.4 ± 1.2%), respectively. The decrease in body weight and percent weight loss was significantly greater in the LWS and NWS groups when compared to the CON group and the percent weight loss was significantly greater in the LWS when compared to both the NWS and CON groups.
A home-based weight loss program utilizing PM and shakes results in clinically significant percent weight loss and the addition of a brief weekly call promotes additional percent weight loss.
本研究旨在比较两种仅在提供外部支持量上存在差异的家庭减肥干预措施的效果。
这是一项为期 12 周的随机对照试验。一组通过每周一次的 10 分钟电话获得有限支持（LWS，n = 35），另一组则不获得每周支持（NWS，n = 28）。LWS 和 NWS 均接受预先包装的餐食（PM）和奶昔。第三组作为对照组（CON，n = 30），不接受干预的任何部分。12 周时的体重减轻是主要结局。饮食（PM、奶昔和水果/蔬菜（F/V）摄入量）和身体活动（PA）由参与者自行监测，每日记录并每周报告。干预组的参与者在研究结束时完成了一份退出调查问卷。
LWS、NWS 和 CON 组的体重减轻和体重减轻百分比分别为 7.7 ± 4.4kg（8.5 ± 4.2%）、5.9 ± 4.1kg（6.0 ± 4.2%）和 0.3 ± 1.9kg（0.4 ± 1.2%）。与 CON 组相比，LWS 和 NWS 组的体重减轻和体重减轻百分比显著降低，与 NWS 和 CON 组相比，LWS 组的体重减轻百分比显著降低。
基于家庭的减肥计划，使用 PM 和奶昔可显著降低体重百分比，增加每周一次的简短电话可促进额外的体重百分比降低。
