Clinical Trial Summary

Background: Different studies have shown that nutritional interventions can be effective in informing and educating the population about the need to follow a healthy diet to prevent obesity and other chronic diseases. However, sometimes this knowledge is difficult to apply in daily life, which is usually marked by lack of time and easy access to food alternatives that are not healthy but can be more comfortable. These difficulties may be greater in families today since the lack of time is greater and it is a greater challenge to get minors to consume a high amount (5 servings a day) of fruits and vegetables. Culinary medicine is an emerging discipline that combines nutrition and gastronomy to increase the prevention and treatment of chronic diseases. Objective: The main objective is to demonstrate whether a culinary-nutritional intervention in families reduces the risk of obesity and increases adherence to a healthy and sustainable diet. Methods: The present project will cover culinary medicine and home-cooking as innovative strategies to improve the eating habits of families through an intervention based on face-to-face nutricional-culinary workshops and online material, where apart from receiving nutritional education, they will be taught a series of culinary techniques (adapted to adults and children) so that they learn to cook in an easy, enjoyable and family-friendly way, with tools to eat healthier in a simple and quick way. The intervention will be carried out with 92 families (dyads 1 adult and 1 child) which will be randomized in a 1: 1: 2 ratio into three groups: group 1 (intervention with families) in which families will attend nutritional-culinary workshops with theoretical and practical information to follow a sustainable Mediterranean diet; group 2 (intervention with parents) in which only parents will attend nutritional-culinary workshops with theoretical and practical information to follow a sustainable Mediterranean diet; and group 3 (control) in which families will attend nutritional workshops with theoretical information to follow a sustainable Mediterranean diet.

Clinical Trial Description

The present pilot study is a multicentric study which will be carried out in two cities of Spain, Alicante and Madrid. The study is divided into two periods: the 10-month intervention period and the 4-month follow-up period. The intervention period will be from May 2022 to February 2023 and the follow-up period from March 2023 to June 2023. A total of 92 families will be included in the present study which will be randomized in a 1: 1: 2 ratio into three groups: group 1 (intervention with families) in which families will attend nutritional-culinary workshops with theoretical and practical information to follow a sustainable Mediterranean diet; group 2 (intervention with parents) in which only parents will attend nutritional-culinary workshops with theoretical and practical information to follow a sustainable Mediterranean diet; and group 3 (control) in which families will attend nutritional workshops with theoretical information to follow a sustainable Mediterranean diet. The sample size was calculated according to the the results on the change in BMI between subjects who followed a culinary intervention vs subjects in the control group of the study by Gatto et al. (2017) (doi:10.1111/ijpo.12102). A sample size of 83 families (55 intervention group families, 28 control group families) was estimated to find a change between groups (intervention vs. control) in the z-score BMI of 0.06 points with a standard deviation (SD) of 0.09 points, with a power of 80% and an alpha error of 5%. Assuming a 10% dropout rate, the initial number of families recruited is increased to 92 (30-31 families in each of the three groups). ;
