Impact of a Supplemental Nutrition Assistance Program-Education (SNAP-Ed) Intervention on Usual Dietary Intake Among Indiana Adults (P04-025-19)

ABSTRACT: Abstract

Objectives

The goal of the Supplemental Nutrition Assistance Program-Education (SNAP-Ed) is to assist low-income households to improve diet quality. The objective of this study was to evaluate the long-term effects of SNAP-Ed nutrition education lessons on diet quality and key nutrient and food group outcomes among Indiana SNAP-Ed-eligible adults.

Methods

The study design was a parallel-arm randomized controlled nutrition education intervention. The intervention consisted of the first 4 lessons of the Indiana adult SNAP-Ed curriculum delivered to participants during the 4 to 10 weeks after their baseline assessment. Participants (?18 yrs) eligible for SNAP-Ed and interested in receiving nutrition education lessons (direct SNAP-Ed) were recruited from 31 Indiana counties (N = 261) and completed baseline assessments from August 2015 to May 2016. Follow-up assessments were conducted approximately 1-year after baseline from August 2016 to May 2017 (n = 103). Dietary intake was assessed using up to 2 24-hour dietary recalls at each assessment time point. The main outcome measures were mean usual nutrient (calcium; vitamins D, A, C, E; magnesium; folate; potassium; fiber; dairy; fruit; vegetable; whole grains) the proportion meeting Estimated Average Requirements, exceeding Adequate Intakes, or meeting daily recommended servings, and diet quality as measured by the Healthy Eating Index-2010. This study is registered at www.clinicaltrials.gov as NCT03436784. Significance was P ? 0.05. Analyses were completed using SAS 9.4.

Results

No effect of direct SNAP-Ed was found on diet quality, nutrient, or food group intake in the treatment compared to the control group between baseline and the 1-year follow-up assessment (P > 0.05).

Conclusions

Direct SNAP-Ed did not improve long-term diet quality, nutrient, or food group intake among Indiana SNAP-Ed eligible adults.
