The National School Lunch Program (NSLP) is one of the most important food assistance programs in the United States to ensure children's food security and healthy development. Previous studies have offered mixed results and challenges in estimating the effects of program participation. This study assesses NSLP's effect on household food security using data from the Survey of Income and Program Participation (SIPP). SIPP collects information on food security that covers four reference months, including both summer (June, July, August) and nonsummer months. The number of summer months in these four reference months varies by SIPP rotation group. These unique features allow this study to address the potential selection bias in the research of NSLP and food security by examining a seasonal difference in program participation. The analysis found that one more summer month in the reference period increases the difference in low food security rates by about 1.5 percentage points between recipients and nonrecipients eligible for free or reduced-price lunch. Findings have important social work and health policy implications for increasing food security among low-income households with children. [ABSTRACT FROM AUTHOR]
