Evidence links trait hostility with components of the metabolic syndrome (MetS), a clustering of cardiometabolic risk factors, but which hostility dimensions (e.g., expressive or cognitive hostility) relate to MetS are not well known. Further, there may be age and sex differences in the extent to which hostility dimensions relate to MetS. The present study evaluated associations between dimensions of hostility and the metabolic syndrome and its individual components as well as the moderating effects of sex and age.
In a cross-sectional sample of 478 employed adults, a principal component analysis from common trait hostility questionnaires yielded a two-factor solution: expressive hostility (anger and aggression) and cognitive hostility (cynicism). Each of these two components of hostility was examined as predictors of each of two aggregated MetS outcomes: a dichotomous measure of MetS, based upon the NCEP-ATP III definition, and a continuous measure based upon the average of standardized scores for each component; and they were examined as predictors of individual MetS components as well.
Expressive hostility was associated with MetS severity (b = 0.110, p = 0.04) and waist circumference (b = 2.75, p = 0.01). Moderation analyses revealed that elevated expressive hostility was associated with elevated waist circumference in women but not men. Cognitive hostility was not related to any metabolic syndrome component or aggregated outcome, and no moderation was observed.
Among multiple individual components and two aggregated scores, only trait dispositions to expressed hostile affect and behavior were associated with MetS severity and waist circumference. The effects were small but statistically significant. The association between cognitive hostility and metabolic syndrome measures may not be robust in a large sample of healthy, midlife adults.
有证据表明特质敌意与代谢综合征（MetS）的各组成部分相关，代谢综合征是一组心脏代谢危险因素的集合，但尚不清楚哪些敌意维度（例如，表达性或认知性敌意）与代谢综合征有关。此外，敌意维度与代谢综合征之间的关联程度可能存在年龄和性别差异。本研究评估了敌意维度与代谢综合征及其个体组成部分之间的关联，以及性别和年龄的调节作用。
在478名在职成年人的横断面样本中，对常见特质敌意问卷进行主成分分析，得出一个双因素解决方案：表达性敌意（愤怒和攻击性）和认知性敌意（愤世嫉俗）。将这两种敌意成分分别作为两种综合代谢综合征结果的预测指标进行检验：一种基于NCEP-ATP III定义的代谢综合征二分法测量指标，以及一种基于各成分标准化分数平均值的连续测量指标；同时也将它们作为个体代谢综合征组成部分的预测指标进行检验。
表达性敌意与代谢综合征严重程度（b = 0.110，p = 0.04）和腰围（b = 2.75，p = 0.01）相关。调节分析显示，表达性敌意升高与女性腰围升高有关，而与男性无关。认知性敌意与任何代谢综合征组成部分或综合结果均无关联，也未观察到调节作用。
在多个个体组成部分和两个综合分数中，只有表达出的敌意情感和行为的特质倾向与代谢综合征严重程度和腰围相关。影响虽小但具有统计学意义。在一大群健康的中年成年人样本中，认知性敌意与代谢综合征测量指标之间的关联可能并不稳健。
