Subjective social status and physical health: The role of negative affect and reappraisal.

Rationale: Having low subjective social status is associated with an array of negative health outcomes. However, the mechanisms linking subjective social status to health are not yet clear. One candidate mechanism is negative affect. Researchers have proposed that having low subjective social status may be associated with higher levels of negative affect, and these higher levels of negative affect may be associated with poor health. However, research demonstrating that status-related negative affect is prospectively associated with health in humans is limited.
Objective: We examined whether negative affect prospectively mediates the relationship between subjective social status and physical health. In addition, we tested whether reappraisal - an affect regulation strategy used to downregulate negative affect - moderates the links among subjective social status, negative affect, and physical health.
Method: We used two-wave longitudinal data from the Midlife in the United States (MIDUS) project to conduct a series of regression, mediation, and moderated mediation analyses to examine the relationships among subjective social status, negative affect, reappraisal, and health (i.e., four outcomes, chronic conditions, somatic symptoms, self-reported health and mortality).
Results: Negative affect mediates the relationship between status and change in morbidity (n = 3289; i.e., change in number of chronic conditions, somatic symptoms, self-reported health) and mortality (n = 4953), such that subjective social status is inversely associated with negative affect, and negative affect is positively associated with poor health. Reappraisal moderates each of these relationships, such that individuals who are low on subjective social status and have high scores on a novel measure of reappraisal experience lower levels of negative affect and better health than individuals who are low on subjective social status but who have low scores on this measure.
Conclusion: These results have important implications for our understanding of subjective social status and how it relates to physical health.
