Purpose: This study adapted a well-established behavior-change intervention to investigate reading and vocabulary learning in a naturalistic context, investigating: (i) if this approach provides an effective way to encourage 11-14-year-old adolescents to read more; and (ii) wether the frequency of exposures to target words predicts vocabulary learning from commercially available fiction. Method: The intervention involved completing a reading diary, including goal-setting, feedback on this goal via text-messages, and rewards. Participants (n = 254, 50% girls) from the South of England were provided with commercially available fiction books to read in their own time and we tracked the number of exposures to particular words found in those books. Results: Our approach did not increase reading amount: the intervention group did not read more than the control group. However, the number of exposures to the tracked words was associated with vocabulary knowledge for those words. This is in line with theories supporting a crucial role of leisure reading for vocabulary learning. Conclusion: Future research should work more collaboratively with teachers and young people to design interventions that are effective, engaging and acceptable for adolescents.

This narrative review revises the scientific evidence of recent years on healthy eating in children and adolescents, making sense of promising avenues of action, from a food system perspective. A conceptual framework is provided to better understand how eating habits of children and adolescents are shaped to identify key multisectoral approaches that should be implemented to promote healthier diets. The following influencing factors are discussed: individual factors (physiological and psychological factors, food preferences and food literacy competencies), factors within the personal and socio-cultural food environments, external food environments, and the supply chain. In each section, the main barriers to healthy eating are briefly discussed focussing on how to overcome them. Finally, a discussion with recommendations of actions is provided, anchored in scientific knowledge, and transferable to the general public, industry, and policymakers. We highlight that multidisciplinary approaches are not enough, a systems approach, with a truly holistic view, is needed. Apart from introducing systemic changes, a variety of interventions can be implemented at different levels to foster healthier diets in children through fostering healthier and more sustainable food environments, facilitating pleasurable sensory experiences, increasing their food literacy, and enhancing their agency by empowering them to make better food related decisions. Acknowledging children as unique individuals is required, through interpersonal interactions, as well as their role in their environments. Actions should aim to enable children and adolescents as active participants within sustainable food systems, to support healthier dietary behaviours that can be sustained throughout life, impacting health at a societal level.

BACKGROUND: Several public interventions have been designed in recent years to urge the intake of vitamin D supplements among the senior population to avoid the direct and indirect consequences associated with vitamin D deficiency. However, the effectiveness of these public campaigns remains quite limited. In an online survey, the current study investigates attitudes towards vitamin D supplements intake and associated behaviours in a representative sample of Danish senior citizens (N = 554) – that is, individuals aged 55 years and above.RESULTS: Approximately half of the sample reported taking vitamin D supplements in the preceding year. Furthermore, being male and having a positive perception of individuals’ own health status increased the probability of being a non‐user. Increasing confidence in the information provided by health authorities (such as medical doctors and pharmacies) is particularly critical for enhancing the likelihood of non‐users to purchase vitamin D supplements. However, also encouraging the uptake of vitamin D supplements in specialized supermarkets with stands and promotions seems an appealing and practical solution to increase seniors’ uptake of vitamin D supplements.CONCLUSIONS: The present study outlines the characteristics of senior Danish non‐users of vitamin D supplements. Additionally, the research provides information on the strategies that could be applied by public organizations to foster vitamin D supplements intake among this target segment of the population. © 2023 The Authors.

Young people are key actors in the transition to more sustainable lifestyles and consumption patterns. Therefore, it is important to understand how environmental values and behaviours change in the transition from youth to young adulthood. In this paper, we trace the development of a pro-environmental orientation from late adolescence through emergent adulthood to young adulthood in a longitudinal survey study that included a cohort of young Danish people born between 1987 and 1992, aged 16–20 in the first study and 30–34 in 2021. The main objective is to explore whether and in which direction the pro-environmental orientation of this cohort changed during late adolescence through emergent and young adulthood. We assess whether the observed changes derive from developmental, cohort or period effects. Overall, we see a weakening of pro-environmental values and attitudes, while the frequencies of pro-environmental behaviours are increasing.

The concept of sustainability has been widely discussed in the public arena by public entities and companies; however, consumers express inconsistency and confusion around the meaning of sustainability. This study aims to provide insights into consumers’ associations with the concept of sustainability in general and within two behavioural domains that represent daily necessities (i.e., food and clothing), in addition to exploring the motivational drivers behind sustainable behaviours. A total of 23 semi-structured interviews were conducted with young consumers in Denmark to address this aim. Consumers perceived the concept of sustainability as complex and mainly related it to environmental aspects, whereas social and economic aspects were less emphasised. The interviewees used examples of sustainable behaviours, which cover the whole consumption-cycle, when interpreting sustainability. Consumers had various motivations to engage in sustainable behaviours and these varied by the stage in the consumption-cycle and domain. The interviewees displayed external motivation (e.g., save money, better taste), introjected motivation (e.g., impress others, public self-consciousness), internalised motivation (e.g., reflection of self) and even intrinsic motivation (e.g., pure interest) to engage in different types of sustainable food or clothing behaviours across the consumption-cycle. Different types of motivations drove the same behaviour, suggesting potential synergies or internal conflicts.

Global meat consumption poses a threat to environmental sustainability and human health. Therefore, moral and health‐related norms connected to eating meat are changing and consumers experience conflicts when choosing between meat and nonmeat options in various situations. To achieve a better understanding of the nature of these conflicts and how consumers cope with them, we study identities related to meat consumption and how they are organized. Identity theories are used as the lens to address the self‐relevance of meat to consumers. Thirteen Danish consumers shared how and why they ate, reduced, or avoided meat in a food‐based photo‐diary and in‐depth interviews, supported by a visualization approach, developed from self‐brand connection methods. Three higher‐order identities (pragmatic idealist, ethical foodie, and healthy hedonist) emerged, governing the consumption, reduction, or avoidance of different meat categories. Identity conflicts between health, moral (e.g., animal welfare), and hedonic concerns were present, but also identity stigma. Coping mechanisms include change of salience and changing patterns of meat consumption. Campaigners promoting a reduction in meat consumption and developers of alternative protein foods can use these insights to target identities and facilitate conflict resolutions. However, more research is needed on how generalizable results are.

Background: The rising childhood obesity rate is a major public health challenge. The objective of this study is to examine key underlying mechanisms for peer-related social influence on preadolescents’ healthy eating behavior by including factors closely linked with the quality of preadolescents’ relationship with peers. Methods: A cross-sectional study was conducted in a convenience sample of 278 Lithuanian preadolescents, recruited from a public school. A questionnaire containing sociodemographic questions, questions about food intake, peer-related social norms of healthy eating, social self-efficacy, vegetable preference, need for peer approval and feeling of belonging were applied. Data was analyzed using structural equation modeling. Results: The results of the SEM showed that social self-efficacy predicts feeling of belonging to the peer group and need for peer approval. Feeling of belonging and need for peer approval predict actual intake of vegetables via injunctive norms of healthy eating. However, neither feeling of belonging nor need for peer approval predicted descriptive norms of healthy eating. Contrary to our expectations, descriptive norms were found to be unrelated with actual intake of vegetables, though vegetable preference predicted actual intake of vegetables. Vegetable preference was not predicted by injunctive or descriptive peers’ social norms of healthy eating. Conclusions: The findings of this study offer insight for informing parents, teachers and for social norms marketing interventions by stressing the importance of social relations when the aim is to encourage healthy eating among preadolescents.

Purpose: The aim of this paper is to demonstrate and discuss a number of child-centric research methods/stimuli involving young children (5-6 years old) in interviews without, and subsequently with their parents. Existing and new methods were selected and developed for a study which aimed at obtaining insights into parents’ and young children’s understandings of children’s influence and family interaction with regard to family food consumption practices. Design/methodology/approach: A total of 35 children were interviewed using semi-structured interviews in five kindergartens. Subsequently, 13 families were interviewed in their homes. The latter interviews included the same children as were interviewed in the kindergarten. The methods discussed include drawings, a desert-island-choice task, a sentence completion task, photographs, vignettes and a video-clip. Findings: When interviewing young children about family decision making influence, the use of engaging methods contributes to the quality of data achieved and to the participants’ enjoyment of their participation. Care should be taken not to overload children with exercises. Visual rather than verbal methods worked better for engaging the children in the research process; for parents all included methods worked well. Research limitations/implications: The current study shows that a method developed specifically for the study (desert-island-choice task) was apt at including all family members’ perspectives; future studies should develop methods that capture shared rather than individual experiences. The study was carried out in wealthy areas in Denmark. It would be highly relevant to broaden the sample to other socio-economic and cultural contexts. Originality/value: The study is based on interviews with children usually deemed too young to interview. The contribution is novel methods that allow for studying the interaction between children and parents and that are not based on reading and writing skills to access the perspectives of 5-6-year old children. Precautions regarding using existing methods are offered.
