Details and patient eligibility


This is a pilot randomized controlled trial to assess the effects of providing produce vouchers during behavioral weight loss treatment in 40 adults with obesity and food insecurity. Participants will be randomized to ProduceRx (12 weekly sessions of in-person, behavioral weight loss counseling (BWL) + produce prescriptions) or a waitlist control (WLC).

Full description

The proposed investigation is a single-site, pilot RCT to assess the effect of BWL and produce vouchers (ProduceRx) on diet quality, weight loss and cardiovascular risk factors among adult participants with food insecurity and obesity. Adults (N=40) will be randomized to a 12-week program that provides weekly, 30-minute BWL sessions + produce vouchers (n=20) or WLC (n=20). Outcomes will be assessed at baseline and at 12 weeks and include questionnaires, and measurements of weight, height, and cardiometabolic risk factors (blood pressure, waist circumference, and pulse). Participants will also be asked to complete two 24-hour dietary recalls.
