Impact of a multicomponent food-as-medicine intervention on behavioral and mental health outcomes for patients with and without food insecurity

Abstract

Background

Increasingly, food-as-medicine (FAM) programs are being implemented as a strategy for improving the health of patients. However, current policies limit nutrition resources to patients with specific chronic condition diagnoses and do not include food insecurity as a qualifying condition.

Objective

Explore the impact of Recipe4Health (R4H), a multicomponent FAM intervention, on behavioral and mental health outcomes in patients with and without food insecurity.

Methods

Patients (n = 336) with diet-related chronic conditions and/or food insecurity were referred to R4H, which included 16-weekly produce deliveries and behavioral intervention sessions. Food security status was assessed using the U.S. Department of Agriculture 6-item survey. Outcomes included vegetable/fruit intake, physical activity (PA) and mental health. Within- and between-group pre-post changes were assessed using repeated-measures linear mixed-effects models, adjusting for baseline.

Results

The majority of patients had one or more chronic conditions (96%) and identified as food insecure (62%). Patients with food insecurity experienced significant increases in daily servings of vegetables/fruit (+0.38 ± 0.15; P = 0.01) and minutes of moderate-to-vigorous PA per week (+28.94 ± 9.84; P < 0.01). Patients with food security did not experience significant increases in vegetables/fruit (P = 0.09) or PA (P = 0.06). Food-insecure and food-secure patients both experienced significant improvements in loneliness, anxiety, and depressive symptoms from baseline (P < 0.01 for all). Between-group differences were observed only for anxiety, where patients with food security experienced significant improvements in anxious symptoms compared to food-insecure patients (–1.24 [–2.33, –0.14]; P = 0.03).

Conclusion

Policymakers may consider expanding eligibility criteria to include food insecurity as an independent qualifying condition for FAM.
