Long-Term Health Effects of Work Trajectories among Middle-Aged and Older Adults: the Mediating Role of Work, Material, and Social Environments.

Using data from 14 waves (2003-2016) of the Korean Labor and Income Panel Study (KLIPS) (N = 1,627 individuals aged 45-64; 22778 observations), in this study, we conducted sequence analysis and a multi-categorical variable mediation analysis (1) to examine to what extent long-term work histories exhibit varying degrees of de-standardization and precariousness using sequence analysis (2) to explore the potential mediating effects of work, material, and social environments in the association between multiple work sequences and self-rated health. We found the coexistence of a relatively stable long-term employment pattern and a high prevalence of precariousness. The health and economic risks of precarious work fall disproportionately on older workers. Future researchers should continue to analyze whether the COVID-19 pandemic will lead to long-term changes in the workforce to improve our understanding of and response to working in later life and its health effects.
