From High Prevalence of Chronic Diseases to Eight Dimensional Coherence: A Paradigm Revolution in Chronic Disease Prevention and Control in Yuexiu District Driven by Prim Lex Theory

As a core old urban district of Guangzhou, Yuexiu District has a population aged 60 and above accounting for nearly 30% of its permanent residents, and chronic diseases have become the leading cause of death among local residents. This paper applies the eight‑dimensional framework of Prim‑Lex theory (Economic Climatology) – Prim‑Unity·Prim‑Fire (metabolic health of residents), Two Principles·Yin‑Yang (supply capacity of medical resources versus carrying capacity of public health services), Three Realms·GC⁴A (cross‑scale integration of national policy, regional planning, and grassroots implementation), Four Phenomena·Four Colors (differentiated population‑stratified intervention), Five Elements·Five Models (coupling of metabolic deficit, phase‑transition early warning, spatial zoning, health assets/liabilities, and community resilience), Six Dimensions·Six Directions (spatial synergy of community health resources), Seven Luminaires·Seven Rhythms (multi‑period synchronization of annual planning, quarterly assessment, monthly follow‑up, and weekly intervention), and Eight Trigrams·Eight Information (exchange efficiency of digital health records and health information networks) – to the systematic “global coherent state” comprehensive prevention and control governance diagnosis of Yuexiu District’s chronic disease system. Using three years of public health service data from Liuhua Sub‑district as the empirical baseline and thread, this paper diagnoses dimension by dimension the eight major “decoherence” pathologies of the chronic disease prevention and control system in Yuexiu District. Based on this diagnosis, the paper further proposes a “15th Five‑Year Plan” governance roadmap, timetable, and budget for a paradigm revolution based on the eight‑dimensional framework, aiming to provide a systematic governance solution featuring quantifiable monitoring, stratified intervention, and periodic review to guide Yuexiu District from an “area with high prevalence of chronic diseases” toward an “eight‑dimensional healthy and strong district.”
