NCT ID: NCT05457439 Active, not recruiting - Physical Activity Clinical Trials

Sustainable-psycho-nutritional Intervention Program and Its Effects on Health Outcomes and the Environment

Start date: October 1, 2022
Phase: N/A
Study type: Interventional

Mexico is going through a major environmental and nutritional crisis, which is related to unsustainable dietary behaviors. Sustainable diets could solve both problems together. However, in Mexico and the world, an intervention program oriented to promoting sustainable diets has not been designed. This study protocol aims to design a 3-stages, 15 weeks, sustainable-psycho-nutritional digital intervention program whose objective is to promote the adherence of the Mexican population to a sustainable diet and to evaluate its effects on dietary water and carbon footprints, metabolic biomarkers, and gut microbiota of this population. The behavior change wheel model and the guide for digital interventions design will be followed. In stage 1, the program will be designed using the sustainable diets model, and the behavior change wheel model. A sustainable food guide, sustainable recipes, and food plans as well as a mobile application will be developed. In stage 2, the intervention will be carried out for 7 weeks, and a follow-up period of 7 weeks, in a sample of Mexican young adults (18 to 35 years) randomly divided into an experimental group (n=50) and a control group (n=50). The nutritional care process model will be used. Anthropometric, biochemical, clinical, dietary, environmental, socioeconomic level and cultural aspects, nutritional-sustainable knowledge, behavioral aspects, and physical activity will be considered. Thirteen behavioral objectives will be included using successive approaches in online workshops twice a week. The population will be monitored using the mobile application that will include behavioral change techniques. In stage 3, the effects of the intervention will be assessed on the dietary water and carbon footprint, lipid profile, serum glucose, and gut microbiota composition of the evaluated population. It is expected to find improvements in health outcomes and a decrease in dietary water and carbon footprints. With this study, the first theoretical-methodological approach to the sustainable-psycho-nutrition approach will be generated.

NCT ID: NCT04148560 Active, not recruiting - Energy Intake Clinical Trials

Free-living Validation of the RFPM in Adolescents

FoodPhone2
Start date: October 1, 2020
Phase: N/A
Study type: Interventional

The primary aim of this small study is to test the validity of the Remote Food Photography Method and an updated SmartIntake app in a sample of adolescents. The investigators will test the validity (accuracy) of the method/app at estimating energy intake in free-living conditions over approximately three days compared to doubly labeled water. This is a small study that has low statistical power, but will provide important data nonetheless and inform future research.
