This study examines how within-person changes in SSP are associated with health-promoting behaviors among middle-aged and older adults in South Korea.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Using ten waves of the Korean Longitudinal Study of Ageing (2006-2024), we estimate individual fixed-effects models on an analytic sample of 65,069 person-wave observations from 10,878 individuals aged 45 and older. We extend the standard symmetric model by adopting an asymmetric fixed-effects framework, which decomposes cumulative SSP increases and decreases into separate parameters.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The symmetric model shows that a one-unit increase in SSP (on a 0-10 scale) is associated with a 0.69 percentage-point increase in regular exercise, after controlling for self-rated health, chronic diseases, functional limitations, and socioeconomic characteristics. The asymmetric decomposition reveals two distinct patterns: exercise responds exclusively to SSP losses (loss-only), while paid health checkups respond only to SSP gains (gain-only). Formal symmetry tests reject equal absolute effects for both outcomes (p &amp;lt; .05).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>These findings provide evidence that associations between changing survival expectations and health behaviors may be asymmetric.
