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

Abstract

Objectives\nThe 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.\n\n\nMethods\nThe 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\xa0yrs) eligible for SNAP-Ed and interested in receiving nutrition education lessons (direct SNAP-Ed) were recruited from 31 Indiana counties (N\xa0=\xa0261) 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\xa0=\xa0103). 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\xa0≤\xa00.05. Analyses were completed using SAS 9.4.\n\n\nResults\nNo 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\xa0>\xa00.05).\n\n\nConclusions\nDirect SNAP-Ed did not improve long-term diet quality, nutrient, or food group intake among Indiana SNAP-Ed eligible adults.\n\n\nFunding Sources\nFunding for this research was provided by Purdue University as part of AgSEED Crossroads funding to support Indiana s Agriculture and Rural Development, Purdue University Frederick N.
