About

The population from Mediterranean countries is abandoning the Mediterranean diet (MD) traditional dietary and lifestyle pattern moving to unhealthier habits because of profound cultural and socio-economic driven lifestyle changes. Families, particularly parents, are responsible for structuring children's early experiences with food and eating as well as for transmitting knowledge of the MD. Educational family approaches can not only lead to more solid food literacy and healthy habits for children in the family but can also improve dietary profiles for adults, thus preventing future health-related problems. There is a lack of adequate study protocol for inducing a positive dietary, environmental and lifestyle behaviour in the family setting. SWITCHtoHEALTHY study aims to evaluate the effects of a multi-component nutritional intervention deployed at family level on the adherence to the MD pattern in families from three Mediterranean countries.

A parallel, randomized, single blind controlled multicentric nutritional intervention study will be conducted in 480 families with children and adolescents among 3-17 years from Spain, Morocco, and Turkey over 13 months. Specifically, 160 families per country will be enrolled in a multi-component intervention and allocated to use digital interactive tools, hands-on educational materials and activities for adolescents, easy-to-eat healthy plant-based snacks for children, or a combination of two or three of the components. There will also be a control group that will receive general advice on healthy eating. The intervention study is scheduled to begin in November 2023.

Through the digital tools the parents will use an interactive App through which they will receive personalized weekly meal plans while the engagement of all the family will be prompted by using a life simulation game. A set of activities for adolescents based on a learning-through-play approach to be carried out within the family and at school will be developed by adolescents and voluntary schoolteachers through co-creation sessions. The innovative and sustainable plant-based snacks will be produced by local food companies and introduced in the children dietary plan as healthy alternatives for between meals. By using a full-factorial design, the independent and combined effects of each intervention component will be tested by comparing the 7 intervention groups with the control group.

Full description

The main outcome will be adherence to the MD assessed through MEDAS and KIDMED validated questionnaires in parents and children respectively. The effectiveness of the multi-component intervention will be evaluated by comparing the MEDAS and KIDMED scores between the control and intervention groups at baseline and at the end of the intervention.The secondary outcomes will include a set of anthropometrical, lifestyle, dietary and socio-economic indicators measured in all family members.

Standardized protocols will be used for the collection of data in the three countries. All data will be collected and evaluated by professional researchers and registered by researchers or study participants in a web platform. Lifestyle, diet, and socio-economic indicators will be self-reported by means of adapted online questionnaires for parent, adolescent, and child.

The study will be carried out in 2 phases:

Phase 1 (month 0 to month 9): the families will be included in the study, they will be assigned to the different intervention groups, and consumption patterns and lifestyle, diet, and socioeconomic indicators will be evaluated through specific questionnaires. In addition, the different educational materials, activities, digital interactive tools and healthy snacks will be developed prior to the start of the intervention study.
Phase 2 (month 10 to month 13): The intervention study will be deployed at family level. Each family will receive the educational materials, digital interactive tools and snacks developed in Phase 1 as assigned. In addition, anthropometric, lifestyle, dietary and socioeconomic indicators will be evaluated through questionnaires.

Three visits will be performed along the study, including one pre-assessment at the beginning of Phase 1 (baseline, month 0), one visit at the beginning of Phase 2 (month 11) and one visit at the end of Phase 2 (month 13).

The impact of the intervention on dietary factors, including MD adherence, diet quality, food intake and MD lifestyle habits, physical activity, and classical anthropometrical parameters, will be assessed in Phase 2 in a 3-month period. However, consumption behaviour and environmental and economic factors will be measured at the baseline (Phase 1) and at the end (Phase 2). The baseline point (month 0) is necessary to assess the aforementioned factors over the course of a year.

Description:

Multi-component intervention with non-invasive approaches: -Digital interactive tools (AI-based Apps): They will consist of a combination of two Artificial Intelligence (AI) Apps that will be used by parents to empower them in their daily dietary choices for children's dietary plan. - Educational materials (Mediterranean-based diet toolkit) and activities: The toolkit will include a set of specific games and activities for kids designed to facilitate the ''learning through playing'' approach improving their understanding of different nutrition themes. The educational activities will be co-designed and carried out by adolescents outside of school hours. - Healthy plant-based snacks: They will be adapted to children's nutritional requirements and to be consumed in-between time on a daily basis. Based on local and traditional products for each country including vegetables, fruits, legumes, seeds and nuts as main ingredients.
