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.
