This cross-sectional study surveyed 835 Brazilian adolescents aged 14–19 attending public schools in Juiz de Fora, MG, using an exploratory questionnaire about eating contexts encompassing meal regularity, eating locations, attention during meals, and company. Cluster analysis identified three groups: appropriate eating contexts at breakfast, lunch, and dinner; inappropriate context at breakfast; and inappropriate context at dinner. Limitations include the cross-sectional design, which precludes causal inference, and inclusion of only public school students, potentially limiting generalizability.

ABSTRACT

Abstract Objective: To describe the eating contexts and estimate their associations with socio-demographic factors in a sample of Brazilian adolescents. Design: Cross-sectional study. We used an exploratory questionnaire about eating contexts (encompassing regularity of meals, places where they occur and if they take place with attention and in company), which was submitted to cluster analysis. Subsequently, three clusters were identified: cluster 1, ‘appropriate eating contexts at breakfast, lunch and dinner’; cluster 2, ‘inappropriate eating context at breakfast’ and cluster 3, ‘inappropriate eating context at dinner’. Multinomial logistic regression models were performed, without and with adjustments, using cluster 1 as reference. Setting: Twenty-nine public schools of Juiz de Fora, MG, Southeast Brazil. Participants: Adolescents, 14–19-year-olds ( n 835). Results: We observed relevant prevalence of adolescents omitting breakfast (52·9 %) and dinner (39·3 %), and who had the habit of eating sitting/lying on the couch/bed or standing/walking, and in front of screens. Breakfast usually occurred unaccompanied (70·8 %); around half (47·5 %) and little over a third (36·1 %) of the sample also would usually have lunch and dinner unaccompanied, respectively. Furthermore, through multivariate analysis, we found associations of eating contexts clusters with female sex (more likely in clusters 2 and 3), age range 14–15-year-olds (less likely in cluster 2) and higher mother’s schooling (more likely in cluster 3). Conclusions: We verified an alarming prevalence of adolescents with eating contexts unaligned with healthy eating recommendations. Additionally, inappropriate eating contexts at breakfast and/or at dinner were associated with socio-demographic factors (sex, age range and mother’s schooling). Keywords: Adolescent, Eating contexts, Feeding behaviour, Food consumption, Socio-economic factors
