Effectiveness of nutrition interventions targeting university-level student populations across the League of Arab States: a systematic scoping review

The university setting is an ideal setting to implement nutrition education interventions. Because the transition to college life often overlaps with young adults' increase in independence in food choice and nutrition related behavior, this is an optimal time to target this population and several models exist to best utilize the college setting to support nutrition education interventions. This review aimed to examine the effectiveness of nutrition interventions in university student populations across the League of Arab States. A scoping review following the PRISMA-ScR guidelines was conducted across 14 databases for relevant publications published through May 2023 to find studies conducted across Arab countries. Quality assessment was conducted using the Effective Public Health Practice Project tool. Seven primary studies were included in this review. Although the interventions and outcome measures were disparate, there were positive impacts of the interventions, including improved nutrition knowledge and nutrition habits, knowledge of nutrient sources, and knowledge about the relationship between diet and disease. Recommendations to maximize the efficacy of nutrition interventions conducted across the League of Arab States include purposeful design of the intervention based on a theoretical framework, the use of a control group in the research design, and follow-up measures to examine post-intervention effects. Consideration should also be given to intervention duration and availability in college-students' schedules. Adaptation of intervention materials, measures and delivery methodologies should emphasize local foods, food culture and dietary practices.
