[Exploration of the classification of public health intervention and its implication for China]

Public health interventions refer to a series of organized and specific measures implemented in specific situations to achieve goals related to improving health, preventing and controlling diseases, and more. As research on intervention measures has deepened, the classification of public health interventions has gradually developed, clarifying the nature, categories and intervention targets of these measures. This typological study can help standardize the concepts of public health interventions, develop, select, and evaluate the effectiveness of intervention measures, and improve the effectiveness of public health actions. This paper reviews the main international classification models of intervention measures, analyzes and summarizes five classification methods of public health interventions, namely, based on goals, nature, objects, hierarchies, and modes of action, and introduces relevant cases. The paper proposes that China should conduct further in-depth and systematic research on public health interventions, develop evidence-based intervention measures and practices, promote the effective transformation of intervention measures and results, and facilitate the development of public health.
