Digital Versus Hybrid Interventions in Promoting Nutrition Knowledge Among Saudi Adolescent Girls

Hybrid intervention that combined face-to-face educational sessions with the integration of technological advancements. They attended weekly 40-minute interactive educational sessions over the course of a month. The educational materials encompass information regarding the components of a healthy balanced diet and an active lifestyle.Throughout the intervention, participants were provided with a range of behavior change techniques to support participants in applying the educational content to improve their dietary and lifestyle habits. The employed behavior change techniques were SMART (specific, measurable, achievable, relevant, time-bound) goal setting, reviewing behavioral goals, problem-solving and environmental restructuring. The technological support for this intervention included the use of a smartphone diet tracker app called MyFitneesPal as well as communication with the interventionists via WhatsApp.

Fully digital intervention, where they received the same educational materials through WhatsApp twice a week over the course of one month. The educational materials were presented through easily understandable posters, brief videos, and followed by short quizzes to reinforce the acquired knowledge. Additionally, the digital intervention incorporated the same behavior change strategies that were utilized in the hybrid group. Participants were also introduced to MyFittnessPal application in order to help them track their dietary habits and monitor their progress since it is considered a tool for self-monitoring and promoting healthy dietary behaviors throughout the intervention period.
