简要总结
The goal of this study is to evaluate the effectiveness of financial incentives delivered in real-time at point of purchase, on low-income consumers' purchase of fruits and vegetables, fruits and vegetables consumption, diet quality, and weight/BMI. The study will test real-time incentives compared to a no-incentive control condition.
详细描述
To address diet quality disparities in low-income families, policy makers and health experts recommend strategies such as financial incentives to promote consumption of fruits and vegetables. Real-time incentives for purchasing fruits and vegetables are promising strategies to improve families' diets and health.
The aims of the study are:
- To test the effects of financial incentives, delivered in real-time at the point of purchase, on low-income consumer purchases of fruits and vegetables
- To evaluate the impact of real-time financial incentives compared to a control condition on FV consumption among adults and their children ,shopping habits, home food environments, diet quality, and weight/BMI
- To adapt mobile platform technology to provide regular feedback to participants to motivate use of the incentive program to increase purchases and consumption of fruits and vegetables
- To evaluate participant satisfaction with real-time healthy food choice incentives technology in both SNAP participants and income-eligible non-SNAP participants
- To assess the acceptability and ease of use of real-time healthy food choice incentives technology among retails supermarket managers and staff in low-income neighborhoods.
