Mexico achieved significant health coverage gains by 2015, but dismantling Seguro Popular and the pandemic caused sharp increases in uninsured rates by 2023. Rebuilding universal health coverage (UHC) requires addressing inequalities and restoring public trust.
Area of Science:
- Public Health
- Health Policy
- Health Economics
Background:
- Universal health coverage (UHC) depends on institutional capacity, equity, political will, and public trust.
- Mexico's health system has faced chronic public confidence issues, impacting UHC progress.
- The study contextualizes Mexico's health coverage trajectory within UHC2030 goals.
Purpose of the Study:
- To provide a comprehensive, disaggregated, and longitudinal assessment of health insurance coverage in Mexico from 2000 to 2023.
- To identify achievements and setbacks in Mexico's journey toward universal health coverage.
- To analyze coverage trends in the context of major policy reforms and disruptions.
Main Methods:
- Utilized nationally representative data from Mexico's National Household Income and Expenditure Survey (ENIGH) (2000-2022, with 2023 projections).
- Classified households into mutually exclusive health insurance categories based on institutional affiliation.
- Analyzed national and subnational coverage trends, incorporating a distance-to-frontier metric to assess progress against historical maximums.
Main Results:
- Mexico reduced the uninsured population from 55% to 6.2% between 2000 and 2015, primarily through Seguro Popular (SP) expansion.
- Following SP's dismantling and the COVID-19 pandemic, uninsured rates surged to 29.1% by 2023, disproportionately affecting southern states and marginalized groups.
- System fragmentation and declining public trust were evident, with several states needing to more than double coverage to reach previous levels.
Conclusions:
- Health coverage gains are reversible without robust institutional foundations, political consensus, and social legitimacy.
- Sustaining UHC necessitates addressing structural inequalities, strengthening institutions, and rebuilding public trust.
- Mexico's experience underscores the need for adaptive, equity-focused institutional restructuring in low- and middle-income countries pursuing UHC.
