Enrollment in a General Nutrition Course Is Associated With Higher Nutrition Knowledge Scores Among University Students.

BACKGROUND AND METHODS: This study examined the association between completion of a general nutrition course (GNC) and nutrition knowledge among university students in the United Arab Emirates (UAE). A cross-sectional online survey was conducted at the University of Sharjah. Nutrition knowledge was compared between students who completed the GNC (GNC group, n = 249) and those who did not (non-GNC group, n = 561). The elective course comprised three modules covering macronutrients and micronutrients, selected nutrition topics, and common nutrition-related diseases. At the end of the academic semester, participants completed the validated 88-item General Nutrition Knowledge Questionnaire-Revised (GNKQ-R), which assesses dietary recommendations, food groups and nutrient sources, healthy food choices, and diet-related diseases and weight management. Each correct response was awarded 1 point, for a maximum score of 88. RESULTS: Overall, 16.4% of participants demonstrated good nutrition knowledge (≥ 64/88). This proportion was higher in the GNC group than in the non-GNC group (26.5% vs. 11.9%, p < 0.001). The GNC group also had a higher mean total knowledge score (55.19 ± 12.50 vs. 52.55 ± 9.75, p = 0.001; Cohen's d = 0.25), with differences observed in three of the four GNKQ-R sections. In the full multivariable model, GNC completion, high Body Mass Index (BMI), enrollment in medical or health-related majors, and more positive self-rated health were associated with higher total scores. CONCLUSIONS: Completion of a general nutrition course was associated with higher nutrition knowledge among university students; however, the magnitude of the difference was modest and overall knowledge levels remained low. Longitudinal and intervention-based studies are needed to assess knowledge retention and whether knowledge differences translate into lifelong dietary behavior change.
