Resource | Research | Nutrition Education WIC Report - Indicators of Diet Quality, Nutrition and Health for Americans by Program Participation Status, 2011–16

This study primarily uses 2011–2016 National Health and Nutrition Examination Survey (NHANES) data to examine bivariate relationships between reported WIC participation and outcomes including diet quality, indicators of nutrition and health, food consumption patterns, and nutrient intakes among 1- to 4-year-old children. Most results presented in this report are unadjusted and descriptive only, and do not infer causality. They are intended to contribute to the evidence base needed to inform future research and, subsequently, WIC policy and practice.
