Previous research suggests that sex differences in cardiovascular reactivity are a function of the gender relevance of the stressor. The authors examined the role of a stressor's gender relevance as a mediator of sex differences in cardiovascular reactivity. The cardiovascular reactivity of 121 male and female college students to the cold-pressor test was compared under feminine- and masculine-relevant stressor instructions. The women were expected to show greater cardiovascular reactivity than the men were to the test relevant to women, whereas the men were expected to show greater cardiovascular reactivity than the women were to the masculine cold-pressor test. Results supported these predictions for systolic blood pressure reactivity, but not heart rate reactivity. Diastolic blood pressure results were mixed. The women showed greater diastolic reactivity than the men did to the feminine-relevant test, but the men did not show greater diastolic reactivity than the women did to the masculine test. The influence of sex differences in cognitive appraisal of situations on cardiovascular reactivity and coronary heart disease is discussed.
先前的研究表明，心血管反应性的性别差异是应激源与性别的相关性的一种表现。作者们研究了应激源与性别的相关性作为心血管反应性性别差异的中介因素所起的作用。在与女性相关和与男性相关的应激源指导语下，比较了121名男女大学生对冷加压试验的心血管反应性。预计女性在与女性相关的试验中比男性表现出更大的心血管反应性，而男性在男性冷加压试验中比女性表现出更大的心血管反应性。结果支持了这些关于收缩压反应性的预测，但不支持心率反应性的预测。舒张压结果不一。在与女性相关的试验中，女性比男性表现出更大的舒张压反应性，但在男性试验中，男性并未比女性表现出更大的舒张压反应性。讨论了情境认知评估中的性别差异对心血管反应性和冠心病的影响。
