College students are at an increased risk for trauma exposure (TE), as well as weight gain and subsequent obesity. Notably, existing research has demonstrated that TE is associated with subsequent obesity. However, there is a dearth of literature looking at this relationship in college students who are at increased risk. Given this increased risk, there is a need to identify protective factors in the wake of TE that may buffer against the adverse impacts of TE on physical health outcomes. As such, the aim of the present study was to examine the relationship between college onset TE on subsequent BMI, and to examine psychological resilience as a buffer in this relationship.
Trauma exposed college students (= 2,281, Mage=18.5, 61.6% female, 50.3% identifying as racial/ethnic minorities) completed measures of TE, weight, height, and resilience. Individuals completed measures at baseline and at spring follow-up time points each year after. Resilience was assessed using the Connor-Davidson Resilience Scale (CD-RISC), and both new onset TE and BMI were assessed at Y2, Y3, and Y4.
There was no significant main effect of new onset TE on BMI, nor an interaction between resilience and new onset TE. There was a main effect of resilience on later BMI, whereby those with higher levels of reported resilience reported higher BMI in subsequent years (Y2: B=.36, <.05; Y3: B= .37= <.01).
The positive association between resilience and BMI is not consistent with our hypotheses. Findings suggest that resilience does not buffer against physical health outcomes.
大学生遭受创伤暴露（TE）的风险增加，同时体重增加及随后肥胖的风险也增加。值得注意的是，现有研究表明创伤暴露与随后的肥胖有关。然而，在处于高风险的大学生中，研究这种关系的文献却很匮乏。鉴于这种风险增加，有必要确定创伤暴露后可能缓冲其对身体健康结果不利影响的保护因素。因此，本研究的目的是探讨大学期间开始的创伤暴露与随后体重指数（BMI）之间的关系，并检验心理复原力在这种关系中作为缓冲因素的作用。
遭受创伤暴露的大学生（n = 2281，平均年龄=18.5岁，61.6%为女性，50.3%为种族/族裔少数群体）完成了创伤暴露、体重、身高和复原力的测量。个体在基线以及之后每年春季随访时间点完成测量。使用康纳 - 戴维森复原力量表（CD - RISC）评估复原力，在第2年、第3年和第4年评估新发生的创伤暴露和BMI。
新发生的创伤暴露对BMI没有显著的主效应，复原力与新发生的创伤暴露之间也没有交互作用。复原力对后期BMI有主效应，即报告复原力水平较高的人在随后几年报告的BMI较高（第2年：B = 0.36，p < 0.05；第3年：B = 0.37，p < 0.01）。
复原力与BMI之间的正相关与我们的假设不一致。研究结果表明，复原力并不能缓冲身体健康结果。
