Food insecurity (FI), characterized by limited or uncertain access to adequate food, has been associated with eating disorders (EDs). This study explored whether FI was associated with ED behaviors, ED diagnosis, current treatment status, and treatment-seeking intentions among adults who completed an online ED screen.
Respondents to the National Eating Disorders Association online screening tool self-reported demographics, FI, height and weight, past 3-month ED behaviors, and current treatment status. Respondents were also asked an optional question about treatment-seeking intentions. Hierarchical regressions evaluated relations between FI and ED behaviors, treatment status, and treatment-seeking intentions. Logistic regressions explored differences in probable ED diagnosis by FI status.
Of 8714 respondents, 25 % screened at risk for FI. FI was associated with greater binge eating (RChange = 0.006), laxative use (RChange = 0.001), and presence of dietary restriction (RChange = 0.001, OR: 1.32) (ps < .05). Having FI was associated with greater odds of screening positive for a probable ED or as high risk for an ED (ps < .05). FI was not associated with current treatment status or treatment-seeking intentions (ps > .05).
Findings add to existing literature supporting a relation between FI and EDs. Implications include a need to disseminate EDs screening and treatment resources to populations affected by FI and to tailor treatments to account for barriers caused by FI.
食物不安全（FI），其特征是获得充足食物的机会有限或不确定，与饮食失调（ED）有关。本研究探讨了 FI 是否与成年人的 ED 行为、ED 诊断、当前治疗状况和治疗意向有关，这些成年人完成了在线 ED 筛查。
国家饮食失调协会在线筛查工具的受访者自我报告了人口统计学资料、FI、身高和体重、过去 3 个月的 ED 行为以及当前的治疗状况。受访者还被问及关于治疗意向的可选问题。层次回归评估了 FI 与 ED 行为、治疗状况和治疗意向之间的关系。逻辑回归探讨了 FI 状态对可能的 ED 诊断的差异。
在 8714 名受访者中，25%的人筛查出有 FI 风险。FI 与暴饮暴食（RChange=0.006）、泻药使用（RChange=0.001）和饮食限制的存在（RChange=0.001，OR：1.32）（p<0.05）呈正相关。有 FI 与筛查出可能的 ED 呈阳性或 ED 风险高的可能性更大（p<0.05）。FI 与当前的治疗状况或治疗意向无关（p>0.05）。
研究结果增加了支持 FI 与 ED 之间存在关系的现有文献。这意味着需要向受 FI 影响的人群传播 ED 筛查和治疗资源，并根据 FI 造成的障碍调整治疗方法。
