Suggests that sex differences in cardiovascular reactivity (CVR) in past research are a function of differences in cognitive appraisal of stressors as masculine or feminine tasks. In the present study, we examined the role of the gender relevance of the stressor as a mediator of sex differences in CVR. The CVR of male and female college students (n = 95) to the cold pressor test (CPT) was compared under masculine and gender-neutral instructions during an anticipation phase, a stressor phase, and a recovery phase. Men were expected to show greater CVR than women to the masculine CPT but not to the gender-neutral CPT. Results supported this prediction for systolic blood pressure reactivity and heart rate reactivity but not for diastolic blood pressure reactivity. The potential influence of sex differences in appraisal of situations on CVR and coronary heart disease is discussed.
过去的研究表明，心血管反应性（CVR）中的性别差异是对应激源进行男性化或女性化任务认知评估差异的一种表现。在本研究中，我们检验了应激源的性别相关性作为CVR性别差异中介因素的作用。在预期阶段、应激源阶段和恢复阶段，按照男性化和性别中立的指导语，比较了95名男女大学生对冷加压试验（CPT）的CVR。预计男性对男性化CPT的CVR会高于女性，但对性别中立的CPT则不然。结果支持了这一预测，即收缩压反应性和心率反应性方面是这样，但舒张压反应性并非如此。讨论了情境评估中的性别差异对CVR和冠心病的潜在影响。
