The Academy of Nutrition and Dietetics, in conjunction with the Commission on Dietetic Registration (CDR), invited The Lewin Group to undertake an analysis of the dietetics workforce. The purpose of the workforce study was to develop a model that can project the supply and demand for both registered dietitians (RDs) and dietetic technicians, registered (DTRs) (collectively referred to as CDR-credentialed dietetics practitioners) as the result of various key drivers of change. The research team was asked to quantify key market factors where possible and to project likely paths for the evolution of workforce supply and demand, as well as to assess the implications of the findings. This article drew on the survey research conducted by Readex Research and futurist organizations such as Signature i and Trend Spot Consulting. Furthermore, members of the Dietetics Workforce Demand Task Force were a source of institutional and clinical information relevant to the credentialed dietetics workforce--including their opinions and judgment of the current state of the health care market for dietetic services, its future state, and factors affecting it, which were useful and were integrated with the objective sources of data. The model is flexible and accommodates the variation in how RDs and DTRs function in diverse practice areas. For purposes of this study and model, the dietetics workforce is composed of RDs and DTRs. This report presents the results of this workforce study and the methodology used to calculate the projected dietetics workforce supply and demand. The projections are based on historical trends and estimated future changes. Key findings of the study included the following: • The average age of all CDR-credentialed dietetics practitioners in baseline supply (2010) is 44 years; approximately 96% are women. • Approximately 55% of CDR-credentialed dietetics practitioners work in clinical dietetics. • The annual growth rate of supply of CDR-credentialed dietetics practitioners declined from 3% in the early 1990s to 1.5% by 2010. • The net supply of CDR-credentialed dietetics practitioners is projected to grow by 1.1% annually. • Approximately 75% of the demand for the dietetics workforce will be met by the 2020 supply of CDR-credentialed dietetics practitioners. • The aging population, health care reform, increased prevalence of certain conditions (including obesity), and growth in the food industry are key factors affecting the demand.
营养与饮食学会（Academy of Nutrition and Dietetics）与营养师注册委员会（Commission on Dietetic Registration，简称 CDR）合作，委托 The Lewin Group 开展一项针对营养专业人员队伍的分析。此次劳动力研究旨在建立一个模型，该模型可以根据各种变化驱动因素，预测注册营养师（RD）和注册营养技师（DTR）（统称 CDR 认证的营养从业人员）的供应和需求。研究小组被要求尽可能量化关键市场因素，并预测劳动力供应和需求的演变路径，以及评估研究结果的影响。本文借鉴了 Readex Research 开展的调查研究，以及 Signature i 和 Trend Spot Consulting 等未来主义组织的研究成果。此外，营养专业人员劳动力需求工作组的成员提供了与认证营养专业人员劳动力相关的机构和临床信息，包括他们对当前营养服务医疗市场状况、未来状况以及影响因素的看法和判断，这些信息是有用的，与客观数据来源相结合。该模型具有灵活性，可以适应 RD 和 DTR 在不同实践领域中的功能差异。出于本研究和模型的目的，营养专业人员劳动力由 RD 和 DTR 组成。本报告介绍了此次劳动力研究的结果以及用于计算预测营养专业人员劳动力供应和需求的方法。预测基于历史趋势和估计的未来变化。该研究的主要发现包括以下内容：
基线供应中所有 CDR 认证的营养从业人员的平均年龄（2010 年）为 44 岁；约 96%为女性。
约 55%的 CDR 认证的营养从业人员从事临床营养学工作。
2010 年，CDR 认证的营养从业人员供应量的年增长率从 20 世纪 90 年代初的 3%下降至 1.5%。
CDR 认证的营养从业人员的净供应量预计将以每年 1.1%的速度增长。
到 2020 年，CDR 认证的营养从业人员的供应量预计将满足约 75%的劳动力需求。
人口老龄化、医疗改革、某些疾病（包括肥胖症）的患病率上升以及食品行业的增长是影响需求的关键因素。
