肥胖症日益流行是一项重大的健康威胁，也是一项重大的公共卫生挑战。迫切需要在临床环境中开发和评估治疗肥胖的实用方法。导致肥胖流行的因素之一是食物的份量。有限的数据可用于视觉或触觉设备的有效性，旨在提高病人的理解和控制的份量。份量控制餐盘是一种市售产品，它可以提供份量大小的视觉提示，并可能通过加强肥胖患者的份量控制来减轻体重。这个工具有望成为饮食咨询的有用辅助工具。我们的目的是评估包括饮食咨询和份量控制餐盘在内的份量控制干预措施，以促进初级保健实践中肥胖患者的体重减轻。我们随机选择65例肥胖患者[体重指数(BMI)≥30和< 40]，进行干预，包括由营养学家咨询并结合份量控制餐盘或常规护理。在初步咨询之后，营养师在1、3和5个月时联系干预组的患者进行简短的随访咨询。常规护理对象得到了关于饮食和锻炼的指导材料。42名（65%）受试者在6个月时返回进行体重评估。部分对照干预组的受试者在3个月时体重较基线变化百分比（±SD）较大（-2.4%±3.7% vs -0.5%±2.2%,p = 0.041），而在6个月时体重较基线变化趋势不显著（-2.1%±3.8% vs -0.7%±3.7%,p = 0.232）。在完成研究的被分配到部分控制干预组的患者中，近一半的人报告说，总体干预是有帮助的，而且大多数人会向其他人推荐这种干预。我们的研究结果表明，结合饮食咨询和份量控制餐盘的份量控制干预可能有效地促进肥胖受试者的体重减轻。份量控制干预作为一种体重控制策略在初级保健中值得进一步评估。当前对照试验NCT01451554
The increasing prevalence of obesity is a significant health threat and a major public health challenge. A critical need exists to develop and evaluate practical methods for the treatment of obesity in the clinical setting. One of the factors contributing to the obesity epidemic is food portion sizes. Limited data are available on the efficacy of visual or tactile devices designed to enhance patient understanding and control of portion sizes. A portion control plate is a commercially-available product that can provide visual cues of portion size and potentially contribute to weight loss by enhancing portion size control among obese patients. This tool holds promise as a useful adjunct to dietary counseling. Our objective was to evaluate a portion control intervention including dietary counseling and a portion control plate to facilitate weight loss among obese patients in a primary care practice. We randomized 65 obese patients [body mass index (BMI) ≥ 30 and < 40] to an intervention including counseling by a dietitian incorporating a portion control plate or to usual care. Following initial consultation, patients in the intervention arm were contacted at 1, 3, and 5 months by the dietician for brief follow-up counseling. Usual care subjects received instructional handouts on diet and exercise. Forty-two (65%) subjects returned to have weight assessed at 6 months. Subjects in the portion control intervention had a greater percentage change (± SD) in weight from baseline at 3 months (-2.4% ± 3.7% vs. -0.5% ± 2.2%; p = 0.041) and a non significant trend in weight change from baseline at 6 months (-2.1% ± 3.8% vs. -0.7% ± 3.7%; p = 0.232) compared with usual care. Nearly one-half of patients assigned to the portion control intervention who completed the study reported the overall intervention was helpful and the majority would recommend it to others. Our findings suggest that a portion control intervention incorporating dietary counseling and a portion control plate may be effective for enhancing weight loss among obese subjects. A portion control intervention deserves further evaluation as a weight control strategy in the primary care setting. Current controlled trials NCT01451554
