dc.description.abstractObjective: To determine and compare the effect of two interventions in reducing12 the plate waste of school lunches.13 Design: A between-group analysis was conducted among children from three14 primary schools: (i) a group receiving intervention A, designed for children and15 focusing on nutrition education and food waste; (ii) a group receiving intervention B,16 intended for teachers and focusing on the causes and consequences of food waste;17 and (iii) a control group with no intervention. For each child, physical weighing18 of individual meals and leftovers was performed on three non-consecutive weeks19 at baseline (T0), 1 week (T1, short term) and 3 months (T2, medium term)20 following the intervention. Plate waste was recorded for a total of 1742 lunches21 during 14 d over eight different menus.22 Setting: Portuguese public primary schools in the city of Porto.23 Subjects: All fourth-grade children (n 212) attending the three preselected schools.24 Results: After intervention A focusing on nutrition education designed for children,25 a decrease in soup waste was observed compared with the control group. The26 effect was greater at T1 (−11·9 (SE 2·8) %; P <0·001) than at T2 (−5·8 (SE 4·4) %;27 P=0·103). The plate waste of identical main dishes decreased strongly at28 T1 (−33·9 (SE 4·8) %; P<0·001). However, this effect was not found at T2 (−13·729 (SE 3·2) %; P <0·001). After intervention B involving teachers, plate waste30 decreased at T2 (−5·5 (SE 1·9) % for soup; −5·4 (SE 2·4) % for identical main dishes).31 Conclusions: Nutrition education designed for children was more effective in the32 short than the medium term. Thus, this kind of intervention was not effective in33 reducing food waste in the medium term. In contrast, an intervention focusing on34 teachers revealed better results in the medium term than in the short term.
