Evaluation of the nutritional habits of second-year high school students in the Seferihisar region with the ecological framework

Abstract

Objective The study aims to identify the nutritional habits of second-year high school students in Seferihisar, Turkey, and the factors associated thereof, based on the Ecological Framework. Methods In this cross-sectional study by a self-reported questionnaire, second-year high school students (n=392) attending public schools in Seferihisar had their nutritional habits measured with the Adolescent Food Habits Checklist scale. The food habit score was calculated and associated factors were evaluated in 4 layers based on the Mary Story’s Ecological Framework (individual factors, social, physical and macro-level environments). The data analysis for the association of these layers with the food habits score was executed through multi-level linear regression. Results Students’ participation rate was 87.7% (n=344). Of all the layers (from individual factors to the influence of the social environment and macro-level environment: nutritional literacy, the food consumption of their peers at school, availability of fruits-vegetables at home, buying junk food at the school canteen, presence of posters at school, etc.), the option for advertised food items was statistically explanatory based on the linear regression analysis (p<0.05). Conclusions The model derived from the Ecological Framework explained 45% of the nutritional habits with an equivalent contribution from the four layers. Availability of healthy food items where the students lived and higher levels of nutritional literacy led to healthy nutritional habits. Having healthy food items sold at school canteens at affordable prices, using posters to promote a healthy diet, and introducing nutrition-related courses into the curricula would support students in developing healthy nutritional habits.

Investigation of education value perception scale's psychometric properties according to CTT and IRT

“…Zorbaz and Bilge (2019) indicated that the approaches based on the Ecological Theory could be effective on the psychosocial skills of delinquent children. Kopan (2019) argued that nutritional habits of 10th grade students are associated with all systems of the Ecological Theory, and Ecological Theory based studies would urge students to a healthier nutrition. Aliyev et al (2021) urges that perception of education value is among the predictors of academic resilience.…”
