- Registration Number
- NCT06258733
- Lead Sponsor
- Hadassah Medical Organization
- Brief Summary
Food literacy (FL) is the capability to make healthy food choices in different contexts, settings and situations. Although eating habits are shaped by different circumstances and skills, most nutrition programs focus on nutrition knowledge alone. Addressing factors such as competencies, self-efficacy and social norms enables sustainable positive change in nutrition behaviour. This study will assess a lay leader-led FL workshop to Arab and Jewish women from disadvantaged communities in the Jerusalem region, utilizing a train-the-trainer approach, and will compare the effectiveness and cost-effectiveness of a lay-led FL intervention to an expert-led intervention.
- Detailed Description
Food literacy (FL) is the capability to make healthy food choices in different contexts, settings and situations. Although eating habits are shaped by different circumstances and skills, most nutrition programs focus on nutrition knowledge alone. Addressing factors such as competencies, self-efficacy and social norms enables sustainable positive change in nutrition behaviour. This study will assess a lay leader-led FL workshop to Arab and Jewish women from disadvantaged communities in the Jerusalem region, utilizing a train-the-trainer approach, and will compare the effectiveness and cost-effectiveness of a manualized FL intervention given by trained lay-leaders vs. the same workshop given by experts.

Group Intervention Description Expert-led FL workshops Expert-led workshops Trained health experts will disseminate the same manualized program in community groups recruited by research staff to match lay-led groups. Lay-led FL workshops Lay-led FL workshops Community lay leaders who underwent training in a manualized program will disseminate the workshop to women in their communities through engaging visual and game-based tools.
- Primary Outcome Measures
Name Time Method Cost-effectiveness ratio of a FL workshop led by trained lay leaders vs. experts After 20 workshops in each arm are implemented. Approximately one year after the beginning of the study. Cost-effectiveness analysis will compare the two alternatives by calculating the incremental Cost-Effectiveness Ratio (ICER). The Markov chain model will be used to predict short and long-term costs and effectiveness in both arms.
Change in the effectiveness in raising FL level of a FL workshop given by trained lay leaders vs. experts At baseline and three months after intervention Level of food literacy will be assessed by using a food literacy self report scale based on Poelman's Self-Perceived Food Literacy (SPFL), including 23 questions, score ranging between 23-65, the higher the score the higher the food literacy level.
- Secondary Outcome Measures
Name Time Method Change in Mediterranean Diet adherence At baseline and three months after intervention Level of adherence to the Mediterranean Diet will be assessed by the Israeli Mediterranean Diet Adherence Screener (I-MEDAS) self-report validated scale. The scale includes 17 items, score ranging between 1-17, the higher the score the higher the food literacy level.
