Acceptability of School Menus: A Systematic Review of Assessment Methods

The school meal promotes healthy eating habits through nutritionally adequate preparations. Consequently, it prevents obesity and malnutrition, favoring learning. This systematic review aimed at investigating the methods for evaluating the acceptance of school menus offered by school feeding programs (SFPs) around the world. Specific search strategies were conducted on PubMed, Lilacs, Web of Science, Scopus, Embase, Google Scholar, and ProQuest Global. The methodological quality of the included studies was assessed using the Meta-Analysis Statistical Assessment and Review Instrument. A total of 89 studies were included. The countries with the highest number of studies were Brazil (n = 42), South Korea (n = 13), and the United States (n = 12). The most used methods (69.66%) were numerical scales, with a higher prevalence for the 5-point scale (50.56%). Other methods included questionnaires and/or interviews with objective and/or subjective questions (44.94%); and mathematical formulas and/or visual estimates evaluating the consumption of food and leftovers (40.45%). The prevalent use of the 5-point hedonic scale may be due to its low cost, simplicity, ease of elaboration, application speed, and student understanding. Mathematical formulas and/or visual estimation were used by about 40% of the studies, but it is difficult to compare studies.
