The Impact of an Educational Intervention on Nutrition Knowledge, Dietary Habits, BMI and Physical Activity, in University Students in the United Kingdom (UK).

The intervention is a randomized-controlled trial with two data collection points: one at the beginning and one at the end of the study. The study will include healthy students from two UK Universities, who they will be randomly assigned either to the intervention or to the control group. Participants in both groups will be asked to undertake measurements and complete questionnaires before and after the study. Measurements include the assessment of BMI, body fat, lean mass, waist-to-hip ratio, systolic and diastolic blood pressure and blood glucose. In addition, nutrition knowledge and dietary habits will be estimated using online questionnaires as well as the level of physical activity using the IPAQ questionnaire and pedometers. Participants in the intervention group will receive access to an educational website including information about fruit and vegetables, fat, sugars, fast-food, meat, salt, meals and snacks, food labels, exercise, and alcohol. Each category will be linked to an online quiz-game that will include questions related to the topic. Students will be asked to play the games as much as they want to improve their knowledge scores. Access to the website and the games will be available for 10 weeks. Participants in the control group will receive no intervention. After 10 weeks, participants will be asked to undertake the same measurements and complete the same questionnaires as they did in the beginning of the study. The study aims to investigate the effectiveness of an online educational intervention, using game elements, on the level of nutrition knowledge of students, as well as, whether any changes in knowledge impact changes in dietary habits, physical activity and weight-related factors.
