The global fast-food industry has grown exponentially, significantly impacting public health by contributing to metabolic disorders like obesity and diabetes. This study aimed to investigate the prevalence, patterns, and predictors of fast-food consumption among 201 undergraduate nursing students at a tertiary-level hospital in India. Using a cross-sectional design, data were collected through a validated self-administered questionnaire and analyzed using R software. Descriptive statistics, chi-square tests, and logistic regression were employed to assess associations between demographic factors and fast-food consumption. Results showed a high prevalence of fast-food consumption (90.0%), with a significant association between fast-food and carbonated drink consumption (p < 0.01). However, no significant predictors of fast-food consumption were identified among demographic factors such as gender, academic year, and residence type. These findings underscore the need for targeted nutritional interventions within nursing curricula to promote healthier dietary habits among future healthcare providers.
