Accepts healthy volunteers: yes
Allocation: NON_RANDOMIZED
Intervention model: PARALLEL
Intervention model description: This is a quasi-experimental study with two arms
Primary purpose: PREVENTION

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.
