Abstract
ObjectiveDetermine how preventable causes of death contribute to the life expectancy gap between Mexico and Spain.MethodsWe used a linear integral decomposition to analyze the impact of preventable mortality on life expectancy between ages 30-75 (temporary life expectancy) between Mexico and Spain in 2018. Additionally, we computed cause-deleted life tables to estimate potential gains in temporary life expectancy. Analyses were stratified by educational attainment, sex, and age.ResultsLow-educated Mexicans showed the largest gains in temporary life expectancy from removing preventable deaths (3.4 years for males, 1.6 for females), partially explaining the gap with Spain. Removing these deaths would close the gap almost entirely due to a higher relative decrease for middle- and high-educated individuals.DiscussionWhile access to adequate healthcare is crucial for improving population health, appropriate non-medical public policies can significantly reduce mortality disparities between Mexico and Spain, especially for individuals from higher educational backgrounds.
