RESUMEN
Food literacy is theorized to be associated with healthy dietary intake. However, empirical knowledge on the association between adolescents' food literacy and dietary intake is limited. The aim of this study was to investigate the association between food literacy and dietary intake among Danish schoolchildren aged 11-13 years. The study applied a cross-sectional design using baseline data from a cluster-based quasi-experimental controlled study in a sample (n = 377) of Danish school children. Mixed model analyses were performed to investigate the associations between overall food literacy as well as its five competencies ("to know", "to do", "to sense", "to care", and "to want") and dietary intake of vegetables, fruit, fish, meat, discretionary foods, and sugar-sweetened beverages. Positive associations were found between overall food literacy (E = 1.493, p = 0.002) as well as the competencies "to know" (E = 1.249, p = 0.027), "to do" (E = 1.236, p = 0.028), "to sense" (E = 1.183, p = 0.029), and "to care" (E = 1.249, p = 0.018) and intake of vegetables. The study also found a positive association between the competency "to want" and intake of fruit (E = 13.50, p = 0.037), "to care" and intake of fish (E = 2.050, p < 0.001), and a negative association between the competency "to want" and intake of meat (E = 0.748, p = 0.003) and sugar-sweetened beverages (E = 0.576, p = 0.0021). No associations were found between overall food literacy or any of its five competencies and intake of discretionary foods. These findings suggest that improving specific aspects of food literacy may have a potential to promote healthier dietary intake, though additional research is needed.

Food literacy (FL) is a goal for many food camps aimed at improving school children's culinary skills and food knowledge. FL in relation to children has been defined as constituting five competencies: "to do" (practical skills),"to know" (knowledge), "to sense" (sensory experiences), "to care" (care for self and others), and "to want" (to be willing to act). However, understanding the processes and mechanisms that relates to school children's FL remain underexplored. The aim of this study was to identify underlying mechanisms operating at a food camp and elucidate how they relate to FL competencies among school children. A qualitative embedded case study design was used to explore this with a Danish food camp programme 'FOODcamp' targeting school-going children aged 12-14 years, constituting an instrumental case. A theory-driven abductive research strategy was used to facilitate analytical generalization. Five schools and nine classes participating in FOODcamp were recruited for the study. Data comprised 10 focus group discussions conducted with children, nine interviews conducted with teachers, and 10 days of observation at FOODcamp. The analysis resulted in 12 conceptually derived mechanisms operating at a food camp namely 'hands-on with food and kitchen utensils', 'use of all senses', 'help and recognition', 'theoretical reflection', 'from farm to table', 'try new and scary things', 'experimenting', 'genuine participation', 'cook from scratch', 'principles', 'meal group community' and 'food group community'. These mechanisms were in various combinations and in a dynamic interplay with contextual conditions related to school children's five FL competencies. The conceptually derived mechanisms may guide future research and practice by highlighting various processes and contextual conditions, given that they are adapted to the specific possibilities of a given context and age group.
RESUMEN
Food literacy (FL) refers to an individual's prerequisites for their engagement with food. Schoolchildren's FL has been defined in terms of five competencies: "to know"(e.g food-related knowledge), "to do" (e.g cooking skills), "to sense" (e.g. less well-explored sensory experiences), "to care" (e.g. taking care of oneself and others) and "to want" (e.g. willingness to take a stand and act). A cluster-based quasi-experimental effectiveness trial on the effects of a school-based intervention, "FOODcamp," on FL, health literacy, and school well-being was conducted. A total of 640 school children in grades 6 and 7 (mean age = 12 years) attended this one-week camp and participated in different food-related classes and activities. Linear mixed models controlling for the nested structure of data showed small but significant effects for the following FL dimensions: "to do (E = 0.098, CI (0.035-0.161), p = 0.002), "to sense" (E = 0.152, CI (0.073-0.232), p < 0.001), and "to know" (E = 0.086, CI (0.022-0.150), p = 0.009) as well as for overall FL (E = 0.078, CI (0.034-0.122), p = 0.001). No effects were found for the dimensions "to want" or "to care". The intervention also had a small but significant effect on children's health literacy but not on school well-being. These findings demonstrate the value of FOODcamp and the positive impacts of a relatively brief intervention on children's FL.

Food literacy (FL) is an aim of food education and cooking interventions, but is defined and measured in different ways. In this study we developed, tested, and validated a FL instrument targeting children aged 12-14 years that builds on a broad 5-dimensional FL concept that includes the competencies of knowing and doing, as well as the rarely investigated competencies of using the senses, caring for others, and wanting to participate as a citizen regarding food issues. The study had 3 phases: 1) item development involving an expert panel; 2) scale testing comprising a face validity test with 12 pupils and a test with 817 pupils, of which 267 took part in a retest; and 3) scale validation including testing dimensionality by confirmatory factor analysis (CFA), internal reliability by Cronbach α, external reliability by intraclass coefficient (ICC), and convergent and predictive validity by regression analysis. CFA showed an acceptable model fit, confirming the concept of FL as 1 factor and its 5 distinct competencies as subfactors. There was good internal reliability for total FL score (α = 0.85) and good external test-retest reliability (ICC = 0.92). Convergent validity for a similar health literacy construct was significant for the total FL scale and its 5 competencies; this was also true for the predictive validity of FL with food intake as an outcome. This 37-item, 5-dimensional FL instrument can be used to assess FL levels in children and can guide food and nutrition education.

BACKGROUND: "We Act" is a health-promoting school intervention comprising an educational, a parental and a school component. The intervention was implemented in 4 Danish public schools with 4 control schools. The objectives were to improve pupils' dietary habits, physical activity, well-being and social capital using the Investigation, Vision, Action & Change (IVAC) health educational methodology. The target group was pupils in grades 5-6. The purpose of this study was to evaluate implementation fidelity and interacting context factors in the intervention schools. METHODS: The Medical Research Council's new guidance for process evaluation was used as a framework. Data were collected concurrently and evenly at the 4 intervention schools through field visits (n = 43 days), questionnaires (n = 17 teachers, 52 parents), and interviews (n = 9 teachers, 4 principals, 52 pupils). The data were analysed separately and via triangulation. RESULTS: A total of 289 pupils participated, and 22 teachers delivered the educational component in 12 classes. In all schools, the implementation fidelity to the educational methodology was high for the Investigation and Vision phases as the teachers delivered the proposed lessons and activities. However, the implementation fidelity to the Action & Change phase was low, and little change occurred in the schools. The pupils' presentation of their visions did not work as intended as an impact mechanism to prompt actions. The implementation of the parental and the school components was weak. The main context factors influencing implementation fidelity were a poor fit into the school-year plan and weak management support. CONCLUSIONS: Although 'We Act' was designed to comply with evidence- and theory-based requirements, IVAC and the health-promoting school approach did not result in change. The time dedicated to schools' preparation and competence development may have been too low. This must be considered in future process evaluation research on health-promoting schools and by school health promotion administrators when planning future school interventions.
