The national nutrition safety net consists of 15 programs that provide millions of low-income Americans access to a healthy and nutritious diet. It has been observed that many low-income individuals are both overweight and participants in one or more nutrition assistance programs. This has led some to question whether participation in the nutrition assistance programs contributes to the growing problem of overweight and obesity. This report presents the conclusions of an expert panel convened by the Food and Nutrition Service to determine if there is scientific evidence of a relationship between program participation and excess weight.

This is the final report for the project, "Analysis of the Current Population Survey Data for Food Security and Hunger Measurement" conducted by Mathematica Policy Research, Inc. 

Over the last decade, food stamp participation rose more sharply than expected following the relatively short and mild recession in the early 1990s and fell more sharply than expected after 1994 during the sustained period of economic growth. Report language accompanying the Agriculture, Rural Development, Food and Drug Administration, and Related Agencies Appropriations Act of 2001 directed the Food and Nutrition Service to study the decline in participation in the Food Stamp Program.

This new edition of the guide documents minor corrections and changes, bringing the procedures described in the original publication up to date.

The advance report of preliminary findings for the period 1995-1998 introduces the second installment in the annual series, Measuring Food Security in the United States.

In this report, data from the NFSPS are used to address several important questions concerning food store access of low-income households, including: (1) At what kinds of stores do low-income households shop? (2) What distances do low-income households travel to reach those stores? (3) What transportation methods do they use to reach their food stores? (4) Do low-income households engage in careful shopping behaviors that can allow them to get the most out of the money and food stamp benefits they spend on food? and (5) In general, how satisfied are low-income Americans with their shopping opportunities?

One of the main objectives of the survey was to examine the food security of FSP participants, in terms of the adequacy of the food available to them and their risk of hunger. The study also examined the amount of nutrients FSP participants used from home food supplies.

This survey is the cornerstone of the food security measurement project begun in 1992 to carry out a key task assigned by the Ten-Year Comprehensive Plan for the National Nutrition Monitoring and Related Research Program.

This publication is based on the WIC Infant Feeding Practices Study (WIC-IFPS) sponsored by FNS. The WIC-IFPS is a one-year longitudinal study, which describes the infant feeding practices over the first year of life among a nationally representative sample of approximately 900 mothers who participated in WIC while they were pregnant.
