Abstract：
The intricate relationship between food systems and health outcomes, known as the food-nutrition-health nexus, intersects with environmental concerns. However, there\'s still a literature gap in evaluating food systems alongside the global syndemic using the complex systems theory, especially concerning vulnerable populations like children. This research aimed to design a system dynamics model to advance a theoretical understanding of the connections between food systems and the global syndemic, particularly focusing on their impacts on children under five years of age. The framework was developed through a literature review and authors\' insights into the relationships between the food, health, and environmental components of the global syndemic among children. The conceptual model presented 17 factors, with 26 connections and 6 feedback loops, categorized into the following 5 groups: environmental, economic, school-related, family-related, and child-related. It delineated and elucidated mechanisms among the components of the global syndemic encompassing being overweight, suffering from undernutrition, and climate change. The findings unveiled potential interactions within food systems and health outcomes. Furthermore, the model integrated elements of the socio-ecological model by incorporating an external layer representing the environment and its natural resources. Consequently, the development of public policies and interventions should encompass environmental considerations to effectively tackle the complex challenges posed by the global syndemic.
摘要：
食物系统和健康结果之间错综复杂的关系，被称为食物-营养-健康关系，与环境问题相交。然而,在使用复杂系统理论评估全球辛迪加的食物系统方面，仍然存在文献空白，特别是像儿童这样的弱势群体。这项研究旨在设计一个系统动力学模型，以促进对食物系统与全球辛迪加之间联系的理论理解。特别关注它们对五岁以下儿童的影响。该框架是通过文献综述和作者对食物之间关系的见解而开发的，健康,以及全球儿童联合犯罪的环境因素。概念模型提出了17个因素，有26个连接和6个反馈回路，分为以下5组：环境，经济,学校相关,家庭相关,和孩子有关。它描绘并阐明了包括超重在内的全球联合组织组成部分之间的机制，患有营养不良，和气候变化。这些发现揭示了食物系统和健康结果之间的潜在相互作用。此外，该模型通过纳入代表环境及其自然资源的外部层，整合了社会生态模型的要素。因此,公共政策和干预措施的制定应包括环境因素，以有效应对全球辛迪加带来的复杂挑战。
