Key result
Steeper delay discounting links to higher cardiometabolic risk, mediated by saturated fat intake.
Why the study?
The study evaluated distinct facets of impulsivity related to cardiometabolic risk to identify specific behavioral mechanisms driving these relationships.

Distinct facets of impulsivity are associated with cardiometabolic risk through specific behavioral pathways, notably physical activity and saturated fat intake.
Should not yet change clinical practice; leaves open causal behavioral pathways in cardiometabolic risk.
OBJECTIVE: The present study evaluated distinct facets of impulsivity related to cardiometabolic risk (CMR) to identify specific behavioral mechanisms driving these relationships. METHOD: = 1,295) between 30 and 54 years old (53% female, 84% White) completed a battery of impulsivity measures, reported their engagement in health behaviors over the past week (i.e., cigarette smoking, alcohol use, physical activity, and dietary intake), and were assessed for CMR factors (i.e., blood pressure, insulin resistance, adiposity, and blood lipids). Structural equation modeling was used to estimate previously established hierarchical models of distinct facets of impulsivity and CMR. Indirect effects through the observed health behaviors were examined for each association between the latent impulsivity factors identified and the latent CMR factor. RESULTS: = .049) indirectly related to CMR through saturated fat intake. CONCLUSIONS: These findings indicate that distinct facets of impulsivity differentially relate to CMR through varied behavioral pathways and identify physical activity and saturated fat intake as being particularly important health behaviors to target when tailoring treatment approaches to the unique behavioral characteristics of individuals high on certain facets of impulsivity.

Emery et al. (2020) conducted a cross-sectional in Cardiometabolic risk (n=1,295). Distinct facets of impulsivity was evaluated on Indirect effect of delay discounting (DDT) on cardiometabolic risk (CMR) through saturated fat intake (β = 0.08, 95% CI 0.001, 0.15, p=0.049). Distinct facets of impulsivity differentially relate to cardiometabolic risk, with steeper delay discounting indirectly increasing cardiometabolic risk through higher saturated fat intake.
