LGBTQ young adults are at increased risk for food insecurity and disordered eating behaviors. Food literacy is a related construct that may also impact disordered eating; however, research on these relationships is limited. It is also not well understood if food security and food literacy relate to disordered eating behaviors differently for LGBTQ and heterosexual individuals. The current study examined these constructs in a sample of college students (n = 572; 22 % LGBTQ), as well as examined sexual orientation as a moderator in the relationship between food insecurity/food literacy and disordered eating outcomes. Results showed that LGBTQ individuals reported greater dieting/restricting, bulimia symptoms, oral control, and binge eating symptoms than heterosexual peers. LGBTQ students were also more likely to be food insecure and had significantly lower food literacy than heterosexual students. Sexual orientation significantly moderated the relationships between food insecurity and overall disordered eating, and between food insecurity and dieting/restricting behaviors. These relationships showed that very low food security was strongly related to disordered eating symptoms for LGBTQ individuals. Sexual orientation did not moderate the relationship between food literacy and disordered eating outcomes. These findings contribute to the overall literature on food insecurity and disordered eating for the LGBTQ community through replicating past findings, and also provide new information about relationships between food literacy, food insecurity, disordered eating, and the role of sexual orientation.
LGBTQ 年轻成年人面临更高的食物不安全和饮食失调行为风险。食物素养是一个相关的概念，也可能影响饮食失调；然而，这些关系的研究有限。目前还不清楚食物安全和食物素养是否以不同的方式与 LGBTQ 和异性恋个体的饮食失调行为相关。本研究在一组大学生样本中（n=572；22%为 LGBTQ）研究了这些结构，同时还研究了性取向在食物不安全/食物素养与饮食失调结果之间的关系中的调节作用。结果表明，LGBTQ 个体报告的节食/限制、贪食症状、口腔控制和暴食症状比异性恋同龄人更多。LGBTQ 学生比异性恋学生更容易感到食物不安全，并且食物素养明显较低。性取向显著调节了食物不安全与总体饮食失调以及食物不安全与节食/限制行为之间的关系。这些关系表明，极低的食物安全与 LGBTQ 个体的饮食失调症状密切相关。性取向并没有调节食物素养与饮食失调结果之间的关系。这些发现通过复制过去的发现，为 LGBTQ 群体的食物不安全和饮食失调整体文献做出了贡献，同时还提供了关于食物素养、食物不安全、饮食失调以及性取向作用之间关系的新信息。
