E-healthy diet literacy is associated with psychological well-being and diet-related risk behaviors among university students in Türkiye: a cross-sectional study

A study conducted among university students in Türkiye has found a link between e-healthy diet literacy and both psychological well-being and diet-related risk behaviors. The research, conducted in Ankara, involved a sample of 331 undergraduates aged 18-26, of which 84.9% were female. The students completed three questionnaires: the e-Healthy Diet Literacy Questionnaire (e-HDLQ), the World Health Organization-Five Well-Being Index (WHO-5), and the Eating Habits Index (EHI).

Using multivariable linear regression and an exploratory covariate-adjusted path analysis with 5,000 bootstrap resamples, the study found that higher e-HDLQ scores were associated with better WHO-5 scores and lower EHI scores. Specifically, a one-standard-deviation increase in e-HDLQ scores was associated with a 3.38 point higher WHO-5 score and a 0.94 point lower EHI score.

However, the authors caution that the associations were modest and the causal relationship cannot be established due to the concurrent measurement nature of the study.
