简要总结
Harris Health System is currently participating, along with two other partners, GoldiFresh Inc., and Brighter Bites, in a cross-sector collaborative home delivery-based Produce Prescription Program (PPRx) pilot initiative that provides consistent access to healthy food plus nutrition education to Medicaid-eligible pregnant women in Harris County, TX, deemed to be at high risk of adverse pregnancy or birth outcomes. The objectives of this study are two-fold: (a) to examine utilization of food basket contents and improvements in diet quality in this home delivery based PPRx program, and (b) to evaluate if and the extent to which utilization of food basket contents outcomes improves with support from an interactive AI-based conversational agent to convert food into healthy meals.
