Abstract

Objective: The current study aimed to investigate the relationship between nutrition literacy (NL) and food habits (FH) in adolescents, and the factors affecting the relationship.

Design: The study used a cross-sectional design. The data were collected using socio-demographic information forms, the Adolescent Nutrition Literacy Scale (ANLS) and the Adolescent Food Habit Checklist (AFHC). The socio-demographic characteristics of adolescents were analysed using descriptive statistics, and the factors affecting NL and FH were determined using the t test, Mann-Whitney U test and ANOVA. The correlation between ANLS and AFHC scores was tested with correlation analysis, and linear regression analysis was employed to predict the change in the NL of adolescents at the level of FH.

Setting: The study was conducted in the city of Izmir in Turkey.

Participants: The study consisted of a total of 467 adolescents.

Results: There was a statistically significant relationship between NL of adolescents and their gender, education level of the father, grade, BMI values and daily lifestyle behaviours (DLB), as well as between their FH and DLB. There was a positive and significant relationship between ANLS and AFHC. The ANLS and its subscales were found to have a statistically significant effect on AFHC. According to the linear regression analysis, the nutritional habits of adolescents were found to be significantly affected by NL (β = 0·357).

Conclusions: As ANLS scores increased, AFHC scores were determined to increase as well. This finding shows that the FH of adolescents have changed positively with increase in their NL.
