    • Abstract:
      Objective: To evaluate the agreement between a 61-item Nutrition Screening Survey (NSS) and 127-item validated Food Frequency Questionnaire (FFQ). Participants: Forty-seven college students (male, n=29; female, n=18), age 21.7±0.4 years, BMI of 23.5±0.4 kg/m². Methods: Participants completed the NSS, Block FFQ, and anthropometric measurements. Pearson’s correlation, paired sample t test, and Bland-Altman plot evaluated agreement between the assessments. Results: Moderate to strong associations between assessments (0.61-0.89, p<0.001) were identified for meals/day, snacks/day, calories, carbohydrate, fiber, grains, non-starchy vegetables, potatoes, legumes, fruit, yogurt, cheese, and eggs. Mean daily meals/day, calories, fat, fiber, grains, fruit, milk, and eggs did not significantly differ between surveys. The Bland-Altman plot analyses indicated no proportional bias for calories, fat, fiber, grains, fruit, milk, and eggs. Conclusions: The NSS and Block FFQ display reasonable agreement, supporting use of the NSS for evaluating a range of dietary components among physically active college students.
