Association between the changes in socialsecurity continuity condition and mortality: MHAS 2001-2018 analysis

Area of Science:

• Gerontology
• Public Health
• Sociology

Background:

• Social security continuity is a critical factor influencing health outcomes in aging populations.
• Understanding the relationship between social security status and mortality is vital for public health policy.

Purpose of the Study:

• To investigate the association between changes in social security continuity and mortality risk.
• To analyze these associations in individuals aged 60 and above using the Mexican Health and Aging Study (MHAS).

Main Methods:

• A retrospective cohort study design was employed.
• Social security continuity was categorized into stable, unstable with SS, unstable without SS, and without SS.
• A probit regression model was used to determine marginal effects, controlling for mortality-related covariates.

Main Results:

• Unstable social security continuity (with or without SS) was linked to a significant increase in mortality probability (52.9% and 50.3%, respectively).
• Multimorbidity also increased mortality probability by 13.3%.
• Being female, having formal education, and being married were associated with reduced mortality risk.

Conclusions:

• Social security enrollment is associated with increased mortality, contrasting with other social health determinants like education.
• Social security continuity and other social factors significantly impact mortality in older adults.
