先前的研究表明，高皮质醇反应比实验室压力源后的低皮质醇反应消耗更多的零食。目前的研究测试了高皮质醇反应者是否也比低皮质醇反应者在应对现场压力时消耗更多的零食。50名绝经前妇女完成了实验室压力测试，提供了唾液样本来评估皮质醇反应状态，然后在接下来的14天内完成了每天的争吵和零食摄入日记。分层多元线性模型显示，在整个样本中，日常争吵与零食摄入量之间存在显著关联，其中争吵次数的增加与零食摄入量的增加有关。这种争吵次数和零食摄入量之间的显著正相关只在高皮质醇反应中观察到，而在低皮质醇反应中没有观察到。这些发现表明，皮质醇对压力的高反应会促进食物摄入。此外，在进食方式变量中，自制、情绪性进食、外在进食和去抑制与零食摄入的关系在高反应组比在低反应组更强。这表明皮质醇。反应性可能在一定程度上解释了饮食方式对应激性饮食的调节作用。研究结果将在未来健康风险的背景下进行讨论。(c) 2006 Elsevier Ltd.版权所有。
Previous research has shown high cortisol reactors to consume a greater amount of snack foods than tow reactors following a laboratory stressor. The current study tested whether high cortisol reactors also consume more snacks than tow reactors in response to field stressors. Fifty pre-menopausal women completed a laboratory stressor, provided saliva samples to assess cortisol reactor status and then completed daily hassles and snack intake diaries over the next fourteen days. Hierarchical multivariate linear modelling showed a significant association between daily hassles and snack intake within the overall sample, where an increased number of hassles was associated with increased snack intake. This significant positive association between number of hassles and snack intake was only observed within the high cortisol reactors and not within the low cortisol reactors. These findings suggest that high cortisol reactivity to stress promotes food intake. Furthermore, the eating style variables of restraint, emotional eating, external eating and disinhibition were more strongly associated with snack intake in high reactors than in low reactors. This suggests that cortisol. reactivity may in part account for the moderating role of eating style on stress-induced eating. The results are discussed within the context of future health risk.
