The impact of fast-food energy posting on college students' food purchases.
Background: The Patient Protection US Affordable Care Act (ACA) energy posting mandate requires restaurant chains to disclose information on the energy content of their food items. Assessments of the effect of menu energy labeling on dietary choices have reported inconsistent findings.
Objectives: This study examined the impact of menu energy labeling on food items purchased by college students after the mandate was enacted nationally.
Methods: Student food sales data from purchases made at 3 fast-food restaurants during the 2017/2018 and 2018/2019 academic years at a university campus were used for the analysis. The total sample included 1662 students on the university meal plan; these students generated 145,295 food transactions at the restaurants over the study period. We utilized a difference-in-differences (DiD) empirical strategy, comparing changes in transaction-level energy purchases at 2 fast-food restaurants B and C (FFRB and FFRC - treatment groups) that posted energy information in the summer of 2018 with another fast-food restaurant A (FFRA - control group) that began posting energy information before the study period.
Results: We observed increases in the mean energy content per transaction after implementing the menu-labeling policy. The DiD estimates found an increase of 20.6 in the mean calories of energy purchased per transaction at the treatment restaurants relative to the control restaurant. In the subgroup analyses, the DiD estimates indicated calories of energy increased: 18.7 for female students, 20.5 for male students, 23.5 for non-Hispanic Black students, 30.2 for students eligible for federal financial aid, and 19.9 for students not eligible for federal financial aid.
Conclusions: The results suggest that the ACA energy menu-labeling policy led to an increase in the energy content per transaction by students at a public university. This paper highlights the need for more research to better understand the determinants of food choice among college students.

The purpose of AJCN is to:
Publish original research studies relevant to human and clinical nutrition.
Consider well-controlled clinical studies describing scientific mechanisms, efficacy, and safety of dietary interventions in the context of disease prevention or health benefits.
Encourage public health and epidemiologic studies relevant to human nutrition.
Promote innovative investigations of nutritional questions employing epigenetic, genomic, proteomic, and metabolomic approaches.
Include solicited editorials, book reviews, solicited or unsolicited review articles, invited controversy position papers, and letters to the Editor related to prior AJCN articles.
Peer Review Process:
All submitted material with scientific content undergoes peer review by the Editors or their designees before acceptance for publication.
