Content of lunchboxes of Dutch primary school children and their perceptions of alternative healthy school lunch concepts.

ABSTRACT:

Objective

To investigate the content of lunchboxes of primary school children and to examine children's support and preferences for alternative healthy school lunch concepts.

Design

A cross-sectional study among Dutch children from seven primary schools. The content of the lunchboxes was assessed by photographs. Support and preferences for alternative lunch concepts were examined via a self-reported questionnaire. Linear regression analyses were used to investigate the associations between children's support and preferences and sex, educational group and migration background.

Setting

The Netherlands.

Participants

Primary school children.

Results

A total of 660 children were included (average 9·9 years old). Most lunchboxes contained sandwiches and a drink. Few lunchboxes contained fruit or vegetables. The alternative school lunch concepts elicited mixed support among children. The lunch concepts 'Sandwiches prepared by the children themselves' and a 'hot lunch buffet' had the highest mean support, while the concept 'a healthy lunch brought from home' was the most preferred concept. Small significant differences were observed depending on sex, educational group and migration background.

Conclusion

Lunchboxes of Dutch children contained sandwiches and a drink but rarely fruit and vegetables. Among different alternatives, children reported the highest support for the preparation of their own sandwiches in class or a hot lunch buffet. Future studies should investigate if these alternative lunch concepts improve the dietary intake of children.

Project description:IntroductionThe majority of children fails to have a healthy diet. Providing a healthy lunch at school is a way to target all children, regardless of ethnic and socioeconomic background. This study aims to investigate the effectivity and feasibility of a co-created healthy school lunch in disadvantaged neighbourhoods of the city of Rotterdam, the Netherlands.Methods and analysisThis is a cluster randomised cross-over trial with five participating primary schools. Schools will be randomised to have an 18 week healthy school lunch the first or second half of the academic year. The other half of the academic year, children will bring their own lunch from home. A tailored lunch concept for each school will be co-created with school staff, parents, children and key-stakeholders.Primary outcome is the dietary content of children's lunches, assessed by observations for all children. Secondary outcomes include healthy lunch-related parameters, like general dietary behaviour, perceived health, taste preferences, concentration in class, and some feasibility outcomes, like satisfaction, implementation at school and affordability for parents. Secondary outcomes will be assessed by questionnaires for children (grades 5-8), parents and teachers. The observations and questionnaires for children and parents will be completed at baseline (September 2023), half way the academic year (January-February 2024) and at the end of the academic year (June-July 2024). Teachers will complete a monthly questionnaire starting in September 2023.Ethics and disseminationThis study obtained ethical approval from the Institutional research Review Board Erasmus MC of Rotterdam, the Netherlands. Informed consent will be collected from all participants (parents, teachers and children 12 years or older) and/or their parents (for children under the age of 16). The findings will be disseminated by conference presentations and publications in scientific peer-reviewed journals.Trial registration numberNCT06058325.

Project description:A research link between conditional reasoning and mathematics has been reported only for late adolescents and adults, despite claims about the pivotal importance of conditional reasoning, i.e., reasoning with if-then statements, in mathematics. Secondary students' problems with deductive reasoning in mathematics have been documented for a long time. However, evidence from developmental psychology shows that even elementary students possess some early conditional reasoning skills in familiar contexts. It is still an open question to what extent conditional reasoning with mathematical concepts differs from conditional reasoning in familiar everyday contexts. Based on Mental Model Theory (MMT) of conditional reasoning, we assume that (mathematical) content knowledge will influence the generation of models, when conditionals concern mathematical concepts. In a cross-sectional study, 102 students in Cyprus from grades 2, 4, and 6 solved four conditional reasoning tasks on each type of content (everyday and mathematical). All four logical forms, modus ponens (MP), modus tollens (MT), denial of the antecedent (DA), and affirmation of the consequent (AC), were included in each task. Consistent with previous findings, even second graders were able to make correct inferences on some logical forms. Controlling for Working Memory (WM), there were significant effects of grade and logical form, with stronger growth on MP and AC than on MT and DA. The main effect of context was not significant, but context interacted significantly with logical form and grade level. The pattern of results was not consistent with the predictions of MMT. Based on analyses of students' chosen responses, we propose an alternative mechanism explaining the specific pattern of results. The study indicates that deductive reasoning skills arise from a combination of knowledge of domain-general principles and domain-specific knowledge. It extends results concerning the gradual development of primary students' conditional reasoning with everyday concepts to reasoning with mathematical concepts adding to our understanding of the link between mathematics and conditional reasoning in primary school. The results inspire the development of educational interventions, while further implications and limitations of the study are discussed.
