创伤后应激障碍（PTSD）似乎会增加肥胖的风险，但PTSD导致体重增加的途径尚不清楚。确定PTSD和肥胖饮食行为之间的联系是必要的，以澄清这一途径，并为PTSD受影响人群的肥胖预防策略的发展提供信息。确定有创伤后应激障碍症状的女性是否比没有创伤后应激障碍症状的女性更容易报告食物成瘾，这是一种对食物依赖的衡量标准。确定PTSD症状发作时的年龄和创伤类型是否影响PTSD食物成瘾。护士健康研究II（NHSII）的49，408名参与者的横断面分析，该研究由1989年从美国14个州招募的年龄在25-42岁的女护士组成。NHSII在2008年确定了终身创伤暴露和PTSD症状，并在2009年确定了目前的食物成瘾。食物成瘾定义为耶鲁食物成瘾量表修订版中≥3个具有临床意义的症状。使用改良Poisson回归估计混杂因素调整的患病率（PR）和95%置信区间（CI）。大约80%的研究样本报告了某种类型的创伤暴露，66%的创伤暴露者报告了至少一种终生PTSD症状。8%的人符合食物成瘾的标准。食物成瘾的患病率随着一生中PTSD症状的数量而增加，PTSD症状数量最多（6-7个症状）的女性的食物成瘾患病率是既没有PTSD症状也没有创伤史的女性的两倍多（PR=2.68; 95%CI：2.41，2.97）。PTSD症状与食物成瘾的关系更密切，当症状发生在较早的年龄。PTSD食物成瘾与创伤类型没有实质性差异。PTSD症状与这组女性食物成瘾患病率的增加有关。减少与PTSD相关的肥胖的策略可能需要心理和行为干预，解决对食物的依赖和/或使用食物来科普痛苦。
Posttraumatic stress disorder (PTSD) appears to increase obesity risk, but the pathways by which PTSD leads to weight gain are not known. Identification of the links between PTSD and obesogenic eating behaviors is necessary to clarify this pathway and inform development of obesity prevention strategies in PTSD-affected populations. To determine whether women with PTSD symptoms are more likely to report food addiction, a measure of perceived dependence on food, than women without PTSD symptoms. To determine whether age at PTSD symptom onset and type of trauma influence the PTSD food addiction association. Cross-sectional analysis of 49,408 participants in the Nurses’ Health Study II (NHSII), a cohort comprised of female nurses who were aged 25–42 at 1989 recruitment from 14 US states. The NHSII ascertained lifetime trauma exposure and PTSD symptoms in 2008 and current food addiction in 2009. Food addiction was defined as ≥3 clinically significant symptoms on a modified version of the Yale Food Addiction Scale. Confounder-adjusted prevalence ratios (PRs) and 95% confidence intervals (CIs) were estimated using modified Poisson regression. Roughly 80% of the study sample reported some type of trauma exposure, with 66% of the trauma-exposed reporting at least 1 lifetime PTSD symptom. Eight percent of the cohort met the criteria for food addiction. The prevalence of food addiction increased with number of lifetime PTSD symptoms, and women with the greatest number of PTSD symptoms (6–7 symptoms) had more than twice the prevalence of food addiction as women with neither PTSD symptoms nor trauma histories (PR=2.68; 95% CI: 2.41, 2.97). PTSD symptoms were more strongly related to food addiction when symptom onset occurred at an earlier age. The PTSD food addiction association did not differ substantially by trauma type. PTSD symptoms were associated with increased food addiction prevalence in this cohort of women. Strategies to reduce obesity associated with PTSD may require psychological and behavioral interventions that address dependence on food and/or use of food to cope with distress.
