简要总结
The goal of this study is to understand how a Produce Prescription Program paired with a behavioral nutrition intervention affect nutrition and overall health in low-income Iowans with type 2 diabetes or pre-diabetes. Research questions include:
- What impact does a produce prescription program paired with a behavioral nutrition intervention on nutrition security compared to the behavioral nutrition intervention alone and usual care groups?
- What impact does a produce prescription program paired with a behavioral nutrition intervention on hemoglobin A1c, fruit and vegetables intake, food security, and related behaviors compared to the behavioral nutrition intervention alone and usual care groups?
Participants of the behavioral nutrition intervention (Produce Your Path) alone will:
- Watch monthly nutrition education videos about topics like planning and budgeting for groceries, reading nutrition labels, eating more fruits and vegetables, and new recipes to try
- Complete a short quiz about their own goals and habits related to the topic
- (Optional): Join a Facebook group to communicate with other participants about their goals, share ideas and recipes, and ask questions
Participants of both the Produce Prescription and Produce Your Path Interventions will:
- Complete each monthly nutrition education module and monthly quiz
- (Optional): Join a Facebook group to communicate with other participants about their goals, share ideas and recipes, and ask questions
- Receive $30.00 per each person in their household monthly to buy fresh fruits and vegetables
Participants of the control group will:
- Follow their usual care for health conditions
- Complete the required data collection for the study

结局指标
主要结局
Nutrition Security
时间窗: From Month 1 of the intervention to the end of the intervention (Month 6)
The USDA's definition of Nutrition Security is 'all Americans have consistent and equitable access to healthy, safe, affordable foods essential to optimal health and well-being'. To measure participant's nutrition security, the investigators will administer the four-item Household Nutrition Security tool developed by the Center for Nutrition \& Health Impact. Participants of every arm of the study will complete the nutrition security items as part of the Baseline Survey (Month 1) and Post-Survey (Month 6). Participants will answer the four questions using a 5-point Likert frequency scale (never to always). The answers correspond to a number, and the overall score is the mean of the four answers, with lower scores indicating less nutrition security.
