This study investigates the relationship between screen time—both academic and recreational—and diet quality among university students aged 18–23. With increasing screen exposure in modern academic and social life, the research aims to determine how screen habits affect food choices and overall nutritional well-being.

A cross-sectional quantitative design was used to survey 162 university students using validated tools, including a researcher-made screen time questionnaire and the Short Healthy Eating Index (sHEI). Data were analyzed through statistical methods to assess correlations and the moderating effects of age and sex.

Findings showed a significant negative relationship between recreational screen time and diet quality, with higher screen time linked to poorer dietary habits. Academic screen time showed a weaker but still notable connection to patterns such as meal skipping. Age and sex were identified as moderating factors in these relationships.

The study concludes that excessive recreational screen time negatively impacts diet quality among university students, while academic screen time shows moderate effects. Interventions promoting mindful screen use and healthier dietary habits are recommended, especially for vulnerable subgroups based on age and sex.
