ABSTRACT
BACKGROUND:
The "Leave No One Behind" (LNOB) principle constitutes the ethical core of the 2030 Agenda for Sustainable Development1.However, as the 2030 deadline approaches, its operationalization remains hindered by foundational ambiguity and a lack of methodological consensus2. While local governments are pivotal for achieving health equity, with an estimated 65% of SDG targets depending on municipal mandates3, they lack standardized guidance to translate broad global norms into effective local policies. This study aims to bridge this gap by synthesizing dispersed guidance into a unified framework for LNOB localization.
METHODS:
We conducted a narrative literature review of 74 documents, comprising academic articles (n=41) and grey literature (n=33). Data were analyzed using a hybrid protocol combining thematic analysis and concept development techniques. This inductive-deductive approach allowed for the synthesis of fragmented evidence into a structured governance model suitable for diverse municipal contexts.
RESULTS:
The analysis yields an adaptive framework organized into four iterative localization stages: (1) Awareness-raising and Governance; (2) Diagnosis; (3) Implementation; and (4) Monitoring and Evaluation. Crucially, these stages are mediated by three cross-cutting normative guidelines: Human Rights, which ensures universality; Intersectionality, which captures overlapping vulnerabilities often obscured by aggregate data4; and a Systems Approach, which manages synergies and trade-offs between sectoral interventions5. The framework redefines localization not as a linear technocratic transfer, but as a dynamic process of "congruence building" between global equity norms and local political realities6.
CONCLUSIONS:
The proposed framework provides municipal actors with a heuristic tool to move beyond administrative compliance toward equity-oriented policymaking. By integrating intersectional diagnostics and systems thinking, local governments can better identify "missing" populations and address the root causes of health disparities, transforming the LNOB pledge from rhetoric into actionable public health practice.
