Diet Quality of Americans by Program Participation Status, 2011–2014

Project Overview

The Food and Nutrition Service’s (FNS) nutrition assistance programs seek to address food insecurity among households with low incomes and improve participants’ diet quality and related health outcomes. This study is the fourth in a series to examine the relationship between diet quality and participation in three such programs: the Supplemental Nutrition Assistance Program (SNAP), the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC), and the National School Lunch Program (NSLP). The SNAP portion of the study also examines how outcomes vary for participants who participate in multiple food assistance programs (SNAP plus WIC or NSLP). Earlier studies used data from the National Health and Nutrition Examination Survey (NHANES).

Specifically, Insight is addressing the following objectives:

  • Examine the relationships between food assistance participation and selected measures of dietary intake assessment, such as diet quality, nutrient intake, and food consumption patterns; and selected measures of health status such as overweight and obesity, body composition, blood pressure, and selected blood biomarkers
  • Assess the feasibility of using advanced regression methods to impute causality from program participation on diet quality and health status outcomes
