href=\"https:\/\/publicexchange.usc.edu\/\">Public Exchange<\/a>. The study was funded by the National Science Foundation and published by the <em>American Journal of Preventive Medicine<\/em>.<\/p>\n<p>Food insecurity is defined as not having access to enough food to maintain an active and healthy lifestyle for all individuals in a household.<\/p>\n<p style=\"font-weight: 400;\">At the end of every year, the USDA collects data from American households about food spending, access to food and other topics through its <a href=\"https:\/\/health.gov\/healthypeople\/objectives-and-data\/data-sources-and-methods\/data-sources\/current-population-survey-food-security-supplement-cps-fss\">Current Population Survey<\/a>. These data showed national food insecurity rates did not change significantly between 2019 (10.5%), 2020 (10.5%) and 2021 (10.2%).<\/p>\n<p style=\"font-weight: 400;\">For California, the USDA reported that food insecurity declined one percentage point in the period 2019\u201321, down from 10.6% in the period 2016\u201318.<\/p>\n<p style=\"font-weight: 400;\">The USDA\u2019s recent data for California stands in stark contrast to <a href=\"https:\/\/publicexchange.usc.edu\/wp-content\/uploads\/2020\/07\/USCLAC-Food-Insecurity-Report-April-%E2%80%93-May-2020.pdf\">data from Los Angeles County<\/a>, collected weekly by the <a href=\"https:\/\/publicexchange.usc.edu\/wp-content\/uploads\/2020\/07\/USCLAC-Food-Insecurity-Report-April-%E2%80%93-May-2020.pdf\">USC research team<\/a> and the U.S. Census\u2019 <a href=\"https:\/\/www.ipr.northwestern.edu\/documents\/reports\/ipr-rapid-research-reports-pulse-hh-data-10-june-2020.pdf\">Household Pulse Survey<\/a>. For example, the data from the <a href=\"https:\/\/www.ipr.northwestern.edu\/documents\/reports\/ipr-rapid-research-reports-pulse-hh-data-10-june-2020.pdf\">Household Pulse Survey<\/a> suggests that from February to April\/May of 2020, L.A. County\u2019s food insecurity rate more than doubled to 21.8%.<\/p>\n<p style=\"font-weight: 400;\">Investigating the frequency with which people are surveyed, and therefore how far back in time they are asked to recall, might explain the significant discrepancy between the USDA\u2019s California data and the available data for L.A. County. Researchers with USC asked Los Angeles County residents questions related to their recent food security experiences 11 times throughout 2021. They found that in December, one-third of respondents who had reported food insecurity earlier in the year did not report it again when asked if they had experienced food insecurity at any point that year.<\/p>\n<p style=\"font-weight: 400;\">\u201cMemory plays a key role in accuracy,\u201d said Kayla de la Haye, the lead researcher and associate professor of population and public health sciences at <a href=\"https:\/\/keck.usc.edu\/\">Keck School of Medicine of USC<\/a>. \u201cThat\u2019s why the time frame during which a survey is conducted is vital, as recall is biased against events that are less frequent or further away.\u201d<\/p>\n<p style=\"font-weight: 400;\">Based on their findings, de la Haye and her colleagues believe the USDA and other government health departments may be underreporting the true extent of food insecurity by one-third.<\/p>\n<p style=\"font-weight: 400;\">\u201cPolicymakers are ill-prepared to address the causes of food insecurity and to develop effective solutions if they don\u2019t have accurate data,\u201d said <a href=\"https:\/\/dornsife.usc.edu\/phd-academy\/student-spotlight-michelle-livings\/\">Michelle Livings<\/a>, a PhD candidate at USC Dornsife\u2019s <a href=\"https:\/\/spatial.usc.edu\/\">Spatial Sciences Institute<\/a> and the study\u2019s first author. \u201cThat\u2019s why it\u2019s so important for government organizations who are doing public health surveillance to reevaluate the frequency with which they survey people on this issue.\u201d<\/p>\n<p style=\"font-weight: 400;\">To improve the accuracy of food insecurity estimates, the researchers recommend that the USDA and other agencies conduct surveys multiple times a year that ask people about their experiences of food insecurity for shorter time periods, over the past week or past month, for example. Further research is needed to determine the optimal recall period for food insecurity surveys, say the study authors.<\/p>\n<p style=\"font-weight: 400;\">The report identifies areas for future research, including:<\/p>\n<ul>\n<li>How under-reporting food insecurity may lead to underestimating its impacts on population health;<\/li>\n<li>To what degree under-reporting of food insecurity within communities of color impacts efforts to document and address food access inequities;<\/li>\n<li>Why individuals with higher incomes were more likely to underreport food insecurity.<\/li>\n<\/ul>\n\n\n\n<\/div>\n\n\n  <\/div><\/div>\n","protected":false},"excerpt":{"rendered":"<p>New research spearheaded by USC Dornsife\u2019s Public Exchange suggests that rates of
