Theoretical Models of Geographic Healthcare Equity in Archipelagos
Conceptualizing maternal health equity across archipelagic geographies demands a synthesis of distinct theoretical frameworks that reconcile institutional coverage with spatial and social stratification. Under a social determinants paradigm, systemic inequities in living standards, education, and regional infrastructure structurally constrain maternal care access across Indonesian communities (W4411428061, 2025). This broad structural view contrasts with institutional equity models that evaluate universal health coverage mechanisms; specifically, evaluations of Indonesia's National Health Insurance demonstrate that while financial risk pooling expands general utilization, it leaves persistent urban-rural and cross-regional disparities intact (crossref-10-53756-jjkn-v6i1-385, 2026). To address these geographic limitations, spatial and multilevel theoretical approaches provide essential granularity. By integrating community-level geography with individual sociodemographic indicators, multilevel frameworks elucidate how extreme geographic isolation and supply-side healthcare deficits interact to drive severe disparities in outer regions such as Papua (crossref-10-22605-rrh9349, 2025). Whereas institutional coverage models emphasize financial entitlement and social determinant frameworks prioritize macro-level societal welfare, multilevel spatial frameworks reveal how island topology fragments service delivery pathways. Synthesizing these theoretical approaches underscores that legal entitlement to maternal care cannot ensure equitable health outcomes without directly addressing the structural friction of archipelagic distance and localized socioeconomic vulnerability.
