The development of healthy eating habits in adolescence is perceived as an effective strategy to avoid health problems in adulthood. The involvement of educational centres’ governing boards, as well as the Educational State and Regional Administrations’, may be necessary to create healthy food environments during the school day. The objective of this study is to identify the relationship between students’ eating habits during the school day and sociodemographic, family and physical activity variables, as well as the existence of a school cafeteria. For this, a cross-sectional study in a stratified random sample of 8068 students of Public Secondary Education High Schools of Andalusia (Spain) has been carried out. The results show that students who are 14 years old or older are more likely to skip breakfast at home (odds ratio (OR): 1.81, 95% confidence interval (CI): 1.55–2.12) than those under this age. Students whose mothers do not have a university education are more likely to consume incomplete breakfasts (OR: 1.83, 95% CI: 1.26–2.65). Snacks with sweets (OR: 1.93, 95% CI: 1.67–2.23), candy in general (OR: 2.75, 95% CI: 2.38–3.19), and bagged crisps (OR: 3.06, 95% CI: 2.65–3.54) were more likely to be consumed in schools with a cafeteria. The factors that significantly influence the eating habits of secondary students in Andalusia include age, sex, parental level of education, physical activity and the existence of a cafeteria.

In order to discover family conceptions and their difficulties with regard to healthy eating habits during the school day, a qualitative study framed in the phenomenological, exploratory, and explanatory perspective has been carried out to detect and describe the aspects and interrelationships that shape the study phenomenon. The researchers performed triangulation techniques and information analysis support with the Atlas-ti programme. As participants, the students’ parents belonging to public secondary education high schools in Huelva, and the capital and its province were included. The participants were intentionally chosen based on established selection and segmentation criteria. Four main categories were obtained from the triangulated analysis. Healthy breakfast, school snack, school cafeteria, and promotion of healthy food measures. Other subcategories were established within them. Families are well aware of the composition of a healthy breakfast, although this is often not translated into practice. Lack of time, comfort and market influence are the main challenges they encounter for their children to acquire healthy habits. The maintenance of healthy habits, their responsibility and control on behalf of the family, and promoting fruit consumption and healthy products from the part of the centre and its cafeteria were highlighted as improvement proposals.

Stress contributes to the development and maintenance of obesity. Mindfulness-based therapies are being used to reduce stress and promote weight reduction and maintenance. This study aimed to determine the efficacy of mindfulness-based interventions for stress and weight reduction in the short, medium, and long term. Searches on PsycINFO, Medline, CINAHL, Scopus, WOS, and Science Direct were conducted until March 2021. Intervention studies with a sample of adults were included; these evaluated a mindfulness-based intervention and used stress and weight or body mass index as outcome variables. These criteria were met by 13 articles. A meta-analysis of 8 of the 13 articles was performed with a random-effects or fixed-effects model, depending on the level of heterogeneity between studies. Mindfulness-based interventions had a small effect on stress reduction over a 3-month period: effect size (standardized mean difference) = −0.29 (95% CI: −0.49, −0.10). However, no significant evidence was found for stress reduction from 3 months onwards, nor for weight or body mass index reduction in any period. Mindfulness-based interventions are effective in reducing stress in the short term, but not in the medium or long term, nor are they effective for weight or body mass index. More robust and longer study designs are needed to determine their effects.

BACKGROUND: Social networks are integrated in our lives and, amongst other functions, they are a means of dissemination. There are numerous social network accounts dedicated to health that could be used as an educational resource. The aim of this study was to evaluate the quality of accounts dedicated to health in different social networks, assessing their content and didactic and technological effectiveness and accessibility. MATERIALS AND METHODS: Observational cross-sectional descriptive study in which an analysis of social networks related to health was carried out from April to June 2021 in Spain. Twenty-eight accounts were analysed using a mixed qualitative-quantitative methodology. Content analysis of the speeches disseminated through the selected accounts was performed. In addition, the quality of the accounts was assessed with the Instrumento de Evaluación de Recursos Educativos Digitales (#IE_RED) (Digital Educational Resources Evaluation Instrument [#IE_RED]). RESULTS: Four categories were identified according to the content: student-focused profiles, specific professionals' profiles, current health issues and profiles promoting a healthy lifestyle. In addition, the quality of the accounts obtained a score that indicates they meet the requirements to be validated as a good educational digital resource but could be improved. Instagram social network accounts and those managed by nurses scored significantly higher. CONCLUSIONS: The analysed accounts were revealed as a quality tool for health dissemination, with varied content and applicable to teaching. Their use could be applied both to the training of health professionals and to the promotion of the population's health.

Health promotion activities in secondary schools are scarce and have little involvement of the teaching staff. Most often, activities are developed from the curriculum that appears in school materials, with little capacity for adaptation and innovation. The aim of this study was to construct and validate a tool to find out teachers’ attitudes towards activities to promote healthy eating in secondary schools. For this purpose, a descriptive study was conducted. The total sample of the study consisted of 200 teachers from secondary schools. Internal consistency was determined by Cronbach’s alpha coefficient globally and by dimension, and with the corrected item–test correlation. The construct validity of the questionnaire was assessed by means of an exploratory factor analysis, for which the principal components method with Varimax rotation was used. A Likert-type scale with nine items and four response options about attitude was designed. The exploratory factor analysis showed a nine-factor solution, of which two had eigenvalues greater than 1. These two factors explained 63.4% of the variance. The Cronbach’s alpha internal consistency index obtained for the global scale was 0.81, and 0.75 and 0.85 for each component. The results obtained with this structure confirmed an adequate reliability and validity of the questionnaire.
