ABSTRACT

Background: Posttraumatic stress disorder (PTSD) is associated with premature onset of chronic health conditions such as cardiovascular disease. Diet and exercise are behavioural contributors to physical health, and research suggests they are influenced by psychiatric symptoms, including PTSD.

Objectives: The aim of this study was to examine longitudinal associations between PTSD and exercise and diet quality and to test if emotion regulation strategies contribute to the link between PTSD and these health behaviours.

Method: A representative sample of US military veterans (n = 860 at Time 1, n = 503 at Time 2, mean age = 63 years, 91.5% male) were assessed twice over the course of approximately three years.

Results: Mediation models revealed that the association between baseline PTSD symptom severity and subsequent diet quality was mediated by emotion suppression (measured at Time 2; indirect B = −.03; 95% CI: −.059 to −.002). Trauma exposure also directly predicted diet quality (B = −.31; p = .003). There were no significant direct or indirect associations between PTSD severity or trauma exposure and exercise engagement.

Conclusions: These results suggest that PTSD symptoms are associated with worse diet quality and that the consumption of unhealthy food may be driven by efforts to suppress emotion. This carries implications for understanding and treating medical comorbidities among those with traumatic stress.

情绪调节与 PTSD、饮食和运动之间的关联:对美国退伍军人的纵向评估

摘要

背景:创伤后应激障碍 (PTSD) 与心血管疾病等慢性健康状况的过早发作有关。饮食和锻炼是身体健康的行为因素,研究表明它们会受到包括创伤后应激障碍在内的精神症状的影响。

目标:本研究的目的是检查 PTSD 与运动和饮食质量之间的纵向关联,并测试情绪调节策略是否有助于 PTSD 与这些健康行为之间的联系。

方法:美国退伍军人的代表性样本(时间 1 时n =  860,时间 2 时n =  503,平均年龄 = 63 岁,91.5% 为男性)在大约三年的时间里接受了两次评估。

结果:中介模型显示,基线 PTSD 症状严重程度与随后的饮食质量之间的关联是由情绪抑制介导的(在时间 2 测量;间接 B = −.0 3;95% CI:−.059 至 −.002)。创伤暴露也可直接预测饮食质量 (B  = −.3· 1; p =  .003)。PTSD 严重程度或创伤暴露与锻炼参与之间没有显着的直接或间接关联。

结论:这些结果表明,PTSD 症状与较差的饮食质量有关,不健康食品的消费可能是由于抑制情绪的努力所致。这对理解和治疗创伤性压力患者的医学合并症具有重要意义。
