在自我报告和实验室实验中，焦虑敏感性（AS）或对躯体唤醒的恐惧与适应不良的饮食行为以及回避运动有关。当前的试点研究试图将这些发现扩展到自然环境中。 32 名成年人样本完成了情感和饮食监测，并在三天的监测期内佩戴了活动记录仪。结果表明，高 AS 与女性总体卡路里消耗量较大、男性消耗量较少有关，并且高 AS 预测，在参与者的负面影响最大程度增加后，两性的卡路里消耗量都会增加。对于体力活动，结果表明 AS 与 BMI 相互作用，因此具有高 AS 的肥胖个体从事不太中等强度的体力活动，而对于正常体重的个体则相反。这些结果表明，AS 可能是导致肥胖的双刃剑危险因素，导致回避运动和卡路里消耗。 (C) 2014 Elsevier Ltd. 保留所有权利。
Anxiety sensitivity (AS), or the fear of somatic arousal, has been linked to both maladaptive eating behavior as well as exercise avoidance in both self-report and laboratory-based experiments. The current pilot study sought to extend these finding to the naturalistic setting. A sample of 32 adults completed affect and dietary monitoring and wore actigraphs across a three-day monitoring period. Results indicated that high AS was associated with greater calorie consumption overall in women and less consumption in men, and high AS predicted an increase in calories consumed following participants' greatest increase in negative affect in both sexes. For physical activity, results indicated an AS by BMI interaction such that obese individuals with high AS engaged in less moderate-intensity physical activity, whereas the opposite was true for normal weight individuals. These results indicate that AS may represent a double-edged risk factor for obesity contributing to both exercise avoidance and calorie consumption. (C) 2014 Elsevier Ltd. All rights reserved.
