A comparison of past-week and past-year measures of food insecurity
Abstract
Methods: Using data from a representative panel survey of Los Angeles adults (N= 1135), we examined inconsistencies in food insecurity measurement. Participants were surveyed about past-week food insecurity ten times in 2021 using the Food Insecurity Experiences Scale, and surveyed about past-year food insecurity in December 2021 using the USDA Household Food Security Survey.
Results: Descriptive statistics showed that of the respondents who reported past-week food insecurity at any time in 2021, only two-thirds reported past-year food insecurity in December 2021—suggesting underreported past-year food insecurity. Logistic regression models indicated that two characteristics were significantly associated with underreporting past-year food insecurity: having reported past-week food insecurity at fewer survey waves, and having a high household income (> 300% of the federal poverty level).
Discussion: These results suggest substantial underreporting of past-year food insecurity, possibly related to recall and/or social desirability bias. Rates of past-year food insecurity should thus be interpreted with caution.
