    Participation in a Produce Prescription Observational Cohort Intervention Is Associated with Improvements in Child Fruit and Vegetable Intake

    by Emily Minkah-Premo, Kofi Essel, Alicia Tucker, Qadira Ali, Laura Fischer

    Background: Produce Prescription Interventions (PRx) are designed to improve food insecurity and diet quality by offering greater access to healthy fruits and vegetables (FV) and nutrition and culinary education. This study evaluated the relationship between participation in a family-based PRx and child FV intake. Methods: Between November 2022 and December 2024, children (0–18 years) and caregiver dyads were recruited to participate in a 6-month PRx that provided 16 pounds of FV per month and virtual nutrition and culinary education sessions monthly. Adult-reported child FV intake data were collected at baseline and post-intervention. The effect of the intervention on child FV intake was evaluated by multiple mixed model regression analyses. Results: A total of 176 dyads completed an FV intake evaluation. Participation in the intervention was associated with a significant increase in fruit (R = 0.21, p = 0.004) and vegetable (R = 0.30, p < 0.0001) consumption. When adjusting for demographic and programmatic variables, the effect of time remained significant. Conclusions: These data support the hypothesis that PRx participation is associated with a modest improvement in FV intake, but barriers to FV intake remain. Further work is needed to understand the optimal PRx design to achieve healthy FV intake in children.

    Qualitative Analysis of a Home-Delivered Produce Prescription Intervention to Improve Food and Nutrition Security

    by Graciela Caraballo, Hemen Muleta, Anar Parmar, Noah Kim, Qadira Ali, Laura Fischer, Kofi Essel

    Background/Objective: In total, 17.9% of households with children experienced food insecurity (FI) in 2023. Produce prescription interventions (PRx) are a viable intervention to address FI and improve diet quality. Few studies have explored home-delivered PRxs in children. The objective of this qualitative study is to explore the experience of a novel PRx among families with young children in households at risk of experiencing FI and diet-related chronic disease. Methods: Semi-structured interviews were conducted with caretakers after the completion of a 12-month PRx. Interviews were recorded, transcribed, and analyzed using thematic analysis to identify emergent themes. Univariate descriptive statistics were used to describe baseline demographics. Results: Twenty-five families were enrolled, from which eighteen completed the program and fifteen agreed to participate in an interview. All participants were African American women. The mean age was 30.2 (±6.4) years old, and the median household size was three. Qualitative data analysis revealed three major themes. (1) The produce delivery partially alleviated financial stress, contributing to increased produce consumption patterns; (2) the intervention positively shifted the nutrition- and cooking-related knowledge and behavior of families; and (3) familial and programmatic barriers affected participation and engagement. Conclusions: PRxs are a viable option to support families to lessen the burden of FI from financial hardship and build healthy dietary habits. These insights can inform future PRx program development, delivery, evaluation, and policy or funding decisions. Future research should examine the sustained impact of PRx on healthy eating, health outcomes among caregivers and their children, and the healthcare cost and utilization rates among PRx participants.

    Food Insecurity Screening and Referral Practices of Pediatric Clinicians in Metropolitan Washington, DC

    by Kofi Essel, Michael Burke, Laura Fischer, Mark Weissman, William Dietz

    Background/Objectives: In 2022, 17.3% of US households with children experienced food insecurity (FI). The objective of this study was to examine pediatric clinicians’ FI screening and management immediately following the release of the American Academy of Pediatrics (AAP) 2015 FI Policy Statement. Methods: Data were collected in 2016 from 85 primary care pediatric clinicians via an online survey of clinicians in the Washington, DC metropolitan area. Descriptive statistics were calculated using univariate/bivariate analyses. Fisher’s exact test and Chi-square tests were used to explore the association between FI screening, health insurance, and clinician demographics. Results: Sixty-six percent of clinicians indicated that they infrequently screened for FI. Only 13% of clinicians used a standardized FI screening tool. Forty-five percent of clinicians screened for FI only when they perceived an acute concern. About 70% of them screened for FI when a patient presented with poor weight gain or was underweight. Conclusions: Immediately after the release of the AAP Policy Statement, it was found that few pediatric clinicians appropriately and frequently screened for FI in our regional sample. Our data emphasize the common misconceptions held by clinicians around FI and the necessity to incorporate training that underscores the invisibility of FI along with effective techniques to screen and intervene.

    Feasibility of a Home-Delivery Produce Prescription Program to Address Food Insecurity and Diet Quality in Adults and Children

    by Laura Fischer, Nia Bodrick, Eleanor R. Mackey, Anthony McClenny, Wayde Dazelle, Kristy McCarron, Tessa Mork, Nicole Farmer, Matthew Haemer, Kofi Essel

    Produce prescription programs aim to improve food insecurity (FI) and nutrition but their effectiveness is unclear. We conducted a pilot study to demonstrate the feasibility and explore the potential impact of a family-based, home-delivery produce prescription and nutrition education program. We measured enrollment, satisfaction, participation, and retention as measure of feasibility. Adult participants answered pre-post self-report questionnaires assessing FI, child and adult fruit and vegetable intake, and culinary literacy and self-efficacy. To understand participants’ lived experiences, qualitative interviews were conducted at the 6-month time point. Twenty-five families were enrolled. Feasibility measures indicate participants were generally satisfied with the program but there were important barriers to participation. Qualitative data revealed themes around reduced food hardship, healthy eating, budget flexibility, and family bonding. Fruit and vegetable consumption increased in a small subgroup of children, but post-intervention intake remained below recommended levels, particularly for vegetables. FI scores were not significantly different post-intervention, but qualitative findings indicated improved access and reliability of food. This is the first intervention of its kind to be evaluated for feasibility and our results suggest the intervention is well-received and supportive. However, further study, with a larger sample size, is needed to understand factors influencing participation and assess effectiveness.
