简要总结
This study primarily aims to compare the efficacy of different approaches to nutrition education intervention delivery in improving nutrition knowledge (NK) among Saudi adolescent girls. A secondary aim is to compare the effectiveness of these interventions in enhancing dietary habits and reducing Generalized Anxiety Disorder (GAD) scores.A randomized sample of 104 Saudi adolescent girls aged 16-18 years from a single high school in Makkah city enrolled in a 4-week lifestyle educational intervention for health promotion. Participants were randomly assigned to either a hybrid or a fully digital nutritional education program. Outcome measures included knowledge (NK), dietary and lifestyle habits assessed by the Healthy Plate Variety Score (HPVS), and mental health evaluated using the Generalized Anxiety Disorder (GAD) scores.

结局指标
主要结局
Nutrition knowledge
时间窗: From enrollment to the end of treatment at 4 weeks
Nutritional Knowledge was assessed using a validated dietary questionnaire, distributed in Arabic (24). The questionnaire comprised 10 items, with a maximum score of 10 points. Each correct response was awarded 1 point, while incorrect answers or uncertain responses received a score of zero. The final score was derived by summing the total points. To classify NK levels, modified Bloom's cut-off points were employed: a score of 80-100% (8-10 points) indicated good NK, 50-79% (5-7.9 points) represented moderate knowledge, and scores below 50% (\<5 points) denoted low knowledge. For analytical purposes, these categories were dichotomized into satisfactory NK (\>80% correct) and unsatisfactory NK (\<80% correct) (7,25).
次要结局
- Generalized Anxiety Disorder Scores (GAD)(From enrollment to the end of treatment at 4 weeks)
- Dietary habits(From enrollment to the end of treatment at 4 weeks)
- Anthropometric measurements (Body mass index)(From enrollment to the end of treatment at 4 weeks)
