Brief summary

The goal of this study is to understand the best practices for implementing produce prescriptions among adults with overweight or obesity experiencing nutrition insecurity. Enrolled participants will receive an 8-week intervention aimed at increasing nutrition knowledge, self-efficacy for healthy eating, and barriers to healthy food access. Participants will be randomly assigned to one of two produce prescription implementation strategies: Program 1: Participants will receive weekly produce vouchers that are redeemable at a local vendor. Program 2. Participants will receive fresh produce delivered directly to the participant's home. These boxes will be tailored based on household size, cooking and preparation preferences, and produce the participant prefers to receive. Researchers will compare engagement in and adherence to the intervention and the patterns of difference in 8-week changes in fruit and vegetable consumption and weight.

Interventions

BEHAVIORALBehavioral Text Messages and Produce Box Delivery

Participants will receive a produce box delivered weekly to the participants home customized based on the participants cooking preferences and household size. Participants will also receive a daily text message aimed to support a healthy diet and lifestyle. These texts will include information to build participants' knowledge and skills for healthy eating. The participants will also include weekly goals that focus on eating a healthy diet. Participants will receive automated, personalized feedback via text messages based on participant goal attainment and daily responses.

BEHAVIORALBehavioral Text Message Program and Produce Voucher

Participants will receive a weekly produce voucher redeemable at a local market vendor for fresh produce of the participant's choice. Participants will also receive a daily text message aimed to support a healthy diet and lifestyle. These texts will include information to build participants' knowledge and skills for healthy eating. The participants will also include weekly goals that focus on eating a healthy diet. Participants will receive automated, personalized feedback via text messages based on goal attainment and daily responses.

Design outcomes

Primary

MeasureTime frameDescription
Number of Participants ReachedFrom screening up to 8 weeksThe investigators will track the number of number of screening completions, number of eligible participants, and number of randomized participants, in addition to number of participants retained.

Secondary

MeasureTime frameDescription
Nutrition Insecurity as Assessed by the 4-item Nutrition Security Screening QuestionnaireBaseline to 8 weeksNutrition insecurity will be assessed using Center for Nutrition Health and Impact questionnaire with a 4-item scale. The higher the score, the greater the level of food security and control an individual has over their nutrition. The four items within the measure are scored from 0 to 4. Then, the measure's score is simply the mean of the responses.
Fruit and Vegetable Consumption as Assessed by the 9-item Mini-Eating Assessment Tool (EAT)Baseline, 4 weeks, and 8 weeksConsumption of food groups will be assessed using the 9-item Mini-Eating Assessment Tool (EAT) questionnaire. Evaluates consumption of key food groups. Fruit and vegetable consumption were each based on two questions within the MINI eat scale, not subscales. Fruit ranges from 1 to 7 where 1 = less than 1 serving per week, and 7 = 4 or more servings per day. Vegetables range from 1 to 6 where 1 = less than 3 servings per week, and 6 = 4 or more servings per day. Mini-EAT score range 0-90. Higher scores better consumption.
Weight (kg)Baseline, 8 weeksWeight will be taken by study staff and measured to the nearest 0.1 kg.
Blood Pressure (mmHg)Baseline, 8 WeeksBlood pressure was measured using the Omron 10 Series ® Upper Arm Blood Pressure Monitor. Participants were instructed to rest for five minutes before two blood pressure readings were taken on the upper arm, one minute apart. Measurements were averaged for analysis.
Health Self-Efficacy as Assessed by the 11-item Healthy Eating and Weight Self-Efficacy ScaleBaseline, 8 weeksSelf-efficacy was measured using the 11-item Healthy Eating and Weight Self-Efficacy Scale. Responses were rated on a Likert scale that ranged from "Strongly Disagree" to "Strongly Agree". Responses were summed to create a total score ranging from 11 to 55, with higher scores representing greater self-efficacy.

Recruitment details

The recruitment and screening processes will be conducted at the Northeast Market. During interactions with community members, the research team will inform individuals of the current study and if interested, help them complete initial screening forms. If the individual remains eligible and interested, a nurse will complete the screening, including measuring height and weight, in a semi-private space at the market.
