OBJECTIVE The present study evaluated distinct facets of impulsivity related to cardiometabolic risk (CMR) to identify specific behavioral mechanisms driving these relationships. METHOD Community adults (N = 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 Neuroticism/negative emotionality was the only latent impulsivity factor directly related to heightened CMR (β = 0.09, 95% confidence interval [CI] [0.01, 0.16], p = .020). Extraversion/positive emotionality indirectly related to lower CMR through greater physical activity (β = -0.04, 95% CI [-0.06, -0.02], p < .001), and measures of inhibition (β = 0.02, 95% CI [0.001, 0.04], p = .045) and delay discounting (β = 0.08, 95% CI [0.001, 0.15], p = .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.

冲动性和中年心脏代谢风险：不良适应性健康行为的作用。

目的本研究评估了与心脏代谢风险（CMR）相关的冲动的不同方面，以识别驱动这些关系的特定行为机制。方法年龄在30至54岁之间的社区成年人（N = 1,295）（女性53％，白人84％）完成了一系列冲动措施，并报告了他们在过去一周中的健康行为（例如，吸烟，饮酒，活动和饮食摄入量），并评估其CMR因素（即血压，胰岛素抵抗，肥胖和血脂）。使用结构方程模型来估计先前建立的冲动性和CMR不同方面的层次模型。对于观察到的潜在冲动因素和潜在CMR因子之间的每个关联，检查了通过观察到的健康行为产生的间接影响。结果神经质/消极情绪是与CMR升高直接相关的唯一潜在冲动因素（β= 0.09，95％置信区间[CI] [0.01，0.16]，p = .020）。外向性/积极情绪与较高的体育活动间接降低CMR（β= -0.04，95％CI [-0.06，-0.02]，p <.001）和抑制措施（β= 0.02，95％CI [0.001） ，0.04]，p = .045）和延迟贴现（β= 0.08，95％CI [0.001，0.15]，p = .049）与通过饱和脂肪摄入引起的CMR间接相关。结论这些发现表明，冲动的不同方面通过不同的行为途径与CMR不同，并且在针对某些冲动方面的个体的独特行为特征量身定制治疗方法时，体育锻炼和饱和脂肪摄入是特别重要的健康行为。 。（PsycInfo数据库记录（c）2020 APA，保留所有权利）。
