目的：评价代餐（MRs）在绝经前妇女减肥干预中的有效性。研究方法和程序：超重绝经前妇女(n = 113；体重指数：25 ~ 35 kg/m(2)；30至50岁)被随机分为三个干预组：A组，营养师主导的干预；B组，营养师主导的结合MRS的干预；在第一年，a组和B组参加了26次小组会议，而C组在26次10分钟的医生-护士团队办公室访问中接受了相同的教育材料。在第二年，参与者每月参加小组研讨会，并与营养师进行偶然访问。结果：在74名完成第一年的受试者中，以办公室为基础的C组的体重减轻效果与传统营养师领导的A组一样（4.3 +/- 6.5% vs 4.1 +/- 6.4%），而B组的体重减轻效果明显更大（9.1 +/- 8.9%;p < 0.02; mean SD）。对于完成第2年的43名受试者，B组的体重减轻百分比（-8.5 +/- 7.0%）与A组（-1.5 +/- 5.0%）和C组（-3.0 +/- 7.0%,p < 0.001）相比有显著差异。讨论：研究结果表明，结合MRS的传统减肥干预在医疗办公室实践和营养师领导的小组环境中作为减肥工具是有效的。
Objective: To evaluate the effectiveness of meal replacements (MRs) in weight loss interventions in premenopausal women.Research Methods and Procedures: Overweight premenopausal women (n = 113; body mass index: 25 to 35 kg/m(2); 30 to 50 years old) were randomized into three interventions: group A, a dietitian-led intervention; group B, a dietitian-led intervention incorporating MRS; and group C, a clinical office-based intervention incorporating MRS. In year 1, groups A and B attended 26 group sessions, whereas group C received the same educational materials during 26 10-minute office visits with a physician-nurse team. In year 2, participants attended monthly group seminars and drop-in visits with a dietitian.Results: For the 74 subjects completing year 1, weight loss in the office-based group C was as effective as the traditional dietitian-led group A (4.3 +/- 6.5% vs. 4.1 +/- 6.4%), while group B maintained a significantly greater weight loss (9.1 +/- 8.9%; p < 0.02; mean SD). For the 43 subjects completing year 2, group B showed significant differences in the percentage of weight loss (-8.5 +/- 7.0%) compared with group A (-1.5 +/- 5.0%) and group C (-3.0 +/- 7.0%; p < 0.001).Discussion: Study results showed that a traditional weight loss intervention incorporating MRS was effective as a weight loss tool in the medical office practice and in the dietitian-led group setting.
