Generating political commitment for ending all forms of malnutrition represents a key challenge for the global nutrition community. Without commitment, the policies, programs, and resources needed to improve nutrition are unlikely to be adopted, effectively implemented, nor sustained. One essential driver of commitment is nutrition actor network (NAN) effectiveness, the web of individuals and organizations operating within a given country who share a common interest in improving nutrition and who act collectively to do so. To inform new thinking and action towards strengthening NAN effectiveness, we use a systems dynamics theoretical approach and literature review to build initial causal loop diagrams (CLDs) of political commitment and NAN effectiveness and a qualitative group model building (GMB) method involving an expert workshop to strengthen model validity. First, a “nutrition commitment system” CLD demonstrates how five interrelated forms of commitment—rhetorical, institutional, operational, embedded, and system‐wide—can dynamically reinforce or diminish one another over time. Second, we present CLDs demonstrating factors shaping NAN effectiveness organized into three categories: actor features, resources, and capacities; framing strategies, evidence, and norms; and institutional, political, and societal contexts. Together, these models generate hypotheses on how political commitment and NAN effectiveness could be strengthened in future and may provide potential starting points for country‐specific conversations for doing so.

为消除一切形式的营养不良产生政治承诺:加强营养参与者网络的系统动力学方法。

作出政治承诺以结束一切形式的营养不良,是全球营养界面临的一项关键挑战。没有承诺,改善营养所需的政策,计划和资源就不可能被采纳,有效实施或维持。承诺的一个重要驱动因素是营养参与者网络(NAN)的有效性,是在给定国家/地区运营的个人和组织的网络,他们共同致力于改善营养,并共同采取行动。为了提供新的思想和行动以增强NAN的有效性,我们使用系统动力学理论方法和文献综述来建立政治承诺和NAN有效性的初始因果循环图(CLD),以及涉及专家研讨会的定性群体模型构建(GMB)方法,以加强模型的有效性。首先,“营养承诺系统” CLD演示了五种相互关联的承诺形式(修辞,机构,运营,嵌入式和系统范围的承诺)如何随着时间的推移动态地相互增强或减少。其次,我们介绍了CLD,这些因素说明了影响NAN有效性的因素,这些因素分为三类:参与者特征,资源和能力;制定策略,证据和规范;以及机构,政治和社会环境。一起,
