Abstract

OBJECTIVE: Our objective was to investigate interactions of psychological resources and socioeconomic status (SES)-as well as potential gender differences and the explanatory role of childhood and adult stress exposures, health behaviors, and negative and positive affect-in predicting markers of systemic inflammation. METHOD: We utilized a sample of adults from the Midlife Development in the U.S. (MIDUS) study who provided biomarker data (N = 1,152). SES was operationalized as a composite of education, income, and occupational prestige, and the psychological resources construct was operationalized as a latent factor measured with optimism, perceived control, and self-esteem. Linear regression models examined these 2 factors and their interaction in predicting interleukin-6 (IL-6) and C-reactive protein (CRP) measured on average 2 years later, as well as 3-way interactions involving gender and the impact of covariate adjustment. RESULTS: Psychological resources interacted with SES in men (for IL-6: p < .001; for CRP: p = .04) but not in women. In men, greater psychological resources was associated with lower concentrations of IL-6 at lower levels of SES but higher concentrations of both markers at higher levels of SES. The inverse association between resources and IL-6 at low SES was moderately attenuated upon adjustment for negative affect. CONCLUSION: Socioeconomic status might modulate the linkage between psychological resources and systemic inflammation in men. At lower levels of SES, resources may be related to lower inflammation in part through lower negative affect. Associations with higher inflammation at higher SES add to growing evidence suggesting that adaptive psychological characteristics may be associated with markers of poorer physiological function under certain conditions.

  • Studies have reported stronger associations of presumably adaptive and maladaptive dispositions with physical functioning and mortality at lower levels of SES, thereby contributing to smaller or larger socioeconomic gradients.

    “Consistent with the vulnerability model, studies have reported stronger associations of presumably adaptive (e.g., perceived control) and maladaptive (e.g., neuroticism and negative affectivity) dispositions with physical functioning and mortality at lower levels of SES, thereby contributing to smaller or larger socioeconomic gradients (33-36).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
