在2001年9月11日世界贸易中心（WTC）灾难中暴露的个体中，创伤后应激障碍（PTSD）及其症状既常见，又与吸烟和体重增加有关。然而，关于创伤后应激障碍症状与体重之间关系的具体过程的信息很少。目前的研究是对焦虑敏感性的初步探索性测试，即对身体内部感觉的恐惧，作为将PTSD症状严重程度与体重指数（BMI）联系起来的可能机制。参与者为147名成年吸烟者（34.0%为女性），他们暴露于世贸中心灾难（通过救援恢复工作或直接目击者）。通过焦虑敏感性（身体、认知和社会关注的总分和亚量表）检测PTSD症状严重程度与BMI之间的直接和间接关联。PTSD症状严重程度通过焦虑敏感性与BMI间接相关；这种效应只存在于对身体感觉意义的生理关注上。专注于降低焦虑敏感性的干预措施（特别是解决对身体感觉的生理担忧）可能有助于解决创伤暴露人群中BMI升高的问题。2016爱思唯尔爱尔兰有限公司版权所有。
Among individuals exposed to the World Trade Center (WTC) disaster on September 11, 2001, post traumatic stress disorder (PTSD) and symptoms are both common and associated with increased cigarette smoking and body mass. However, there is little information on the specific processes underlying the relationship of PTSD symptoms with body mass. The current study is an initial exploratory test of anxiety sensitivity, the fear of internal bodily sensations, as a possible mechanism linking PTSD symptom severity and body mass index (BMI). Participants were 147 adult daily smokers (34.0% female) exposed to the WTC disaster (via rescue recovery work or direct witness). The direct and indirect associations between PTSD symptom severity and BMI via anxiety sensitivity (total score and subscales of physical, cognitive, and social concerns) were examined. PTSD symptom severity was related to BMI indirectly via anxiety sensitivity; this effect was specific to physical concerns about the meaning of bodily sensations. Interventions focusing on anxiety sensitivity reduction (specifically addressing physical concerns about bodily sensations) may be useful in addressing elevated BMI among trauma-exposed persons.
