ABSTRACT 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.
