Introduction: The issue of healthy eating of schoolchildren as one of the most important factors in maintaining and improving health of the younger generation, as well as preventing non-communicable diseases in the population as a whole, is recognized as a socially significant problem at the international level and in many countries of the world, including Russia.
Objective: To establish characteristics of the diet, food preferences, and awareness about the importance of healthy eating among 11–12-year-old schoolchildren in order to determine teaching content promoting healthy eating practices in this age group.
Materials and methods: The questionnaire-based survey was conducted from May to August 2023 involving 150 fifth-year schoolchildren from Cherepovets (mean age: 12.3 ± 0.37 years). The questionnaire contained closed-ended questions grouped into three blocks corresponding to the subject of study and the answers were then analyzed using quantitative, qualitative, and generalization methods.
Results: Nutritional imbalance in the 11–12-year-old schoolchildren was established. We noted low daily consumption of potable water in 32.0 % of the respondents, the absence of fermented dairy products, cheese or cottage cheese (17.8 % and 18.7 %, respectively), as well as fish (51.3 %), meat (16.7 %), eggs (23.5 %), and porridge (36.2 %) in the diet. At the same time, we observed a high frequency of daily consumption of sausages (28.7 %), mayonnaise or ketchup (19.3 %) accompanied by low daily intake of fresh fruits and vegetables (ca. 58.0 %). Preferring sweet carbonated drinks to juices (41.5 %) and fried foods (52.6 %) indicated unhealthy dietary habits. 42.0 % of the teenagers had certain gaps in knowledge about healthy eating.
Conclusions: The established dietary habits, food preferences, and perceptions of healthy eating among 11–12-year-old schoolchildren indicate the need for proper nutrition education at school.
