As the focus of chronic non-communicable diseases (hereinafter referred to as chronic diseases) prevention and control shifts toward communities, primary healthcare institutions are playing an increasingly prominent role in nutrition health promotion and early intervention of chronic diseases. However, the current capacity for building nutrition clinics and providing multidisciplinary services at the primary level remains generally weak, underscoring the urgent need to explore practical new paths for the integration of clinical care and public health. Based on literature reviews and expert discussions, this consensus employed the modified Delphi method and the Joanna Briggs Institute (JBI) evidence pre-grading system to systematically construct a precision nutrition health management system centered on the N-RCSP (nutrition, rehabilitation, chinese medicine, sports, psychology) "five-in-one" integrated intervention strategy. It specifies the construction principles, personnel and equipment allocation, and informatization standards for primary nutrition clinics, and outlines a digital closed-loop service process covering "screening-assessment-intervention-monitoring-follow-up". The N-RCSP precision nutrition health management model serves as an effective tool for implementing the integration of clinical care and public health, and can comprehensively enhance the non-pharmacological intervention capacity for chronic diseases and health management levels in primary healthcare institutions. Promoting this model helps lower the technical threshold for primary general practitioners to deliver professional nutritional interventions and facilitates multidisciplinary collaboration.

随着慢性非传染性疾病（以下简称慢性病）防控重心向社区前移，基层医疗卫生机构在营养健康促进及慢性病早期干预中的作用日益凸显，但当前基层营养门诊建设及多学科协作服务能力普遍薄弱，亟须探索切实可行的医防融合新路径。本共识基于文献回顾与专家讨论，采用改良德尔菲法及乔安娜·布里格斯研究所（JBI）证据预分级系统，系统构建了以N-RCSP（营养、康复、中医、运动、心理）"五位一体"干预策略为核心的精准营养健康管理体系，详细明确了基层营养门诊的建设原则、人员及设备配置、信息化标准，并梳理了涵盖"筛查-评估-干预-监测-随访"的数字化闭环服务流程。N-RCSP精准营养健康管理模式是落实医防融合的有效抓手，能全面提升基层医疗卫生机构的慢性病非药物干预与健康管理水平，推广该模式有助于降低基层全科医生实施专业营养干预的技术门槛，促进多学科协作。
