Area of Science:
- Nutrition Science
- Digital Health
- Behavioral Science
Background:
- Urgent need to shift dietary patterns towards sustainable healthy diets, balancing health, environmental, and socioeconomic factors.
- Few interventions address all dimensions of sustainable healthy diets simultaneously using digital health methods.
Purpose of the Study:
- Assess feasibility and effectiveness of a digital intervention for sustainable healthy diet adoption.
- Evaluate changes in food groups, food waste, and fair food sourcing.
- Identify intervention mechanisms, spillover effects, and the role of socioeconomic status.
Main Methods:
- Series of ABA n-of-1 trials over one year with 21 participants across socioeconomic statuses.
- Intervention includes text messages and web-based feedback based on app-assessed eating behaviors.
- Quantitative (surveys) and qualitative (interviews) data collection for individual and group analyses.
Main Results:
- Participant recruitment began October 2022.
- Full study results are anticipated by October 2023.
Conclusions:
