Screening for food insecurity
Beginning in 2015, an AAP policy statement charged pediatricians to “screen and intervene” with regard to food insecurity and their patients, Dr. Essel said. The statement also called for pediatricians to advocate for programs and policies that end childhood food insecurity.
The policy statement recommended a validated two-question screening tool called the Hunger Vital Sign:
1. “Within the past 12 months, we worried whether our food would run out before we got money to buy more.”
2. “Within the past 12 months, the food that we bought just didn’t last and we didn’t have money to get more.”
But in screening, you need to be conscious of how dignity intersects with food insecurity concerns, Dr. Essel said.
“We need to create dignity for our families,” he said. “We need to create a safe environment for our families and use appropriate tools when necessary to be able to identify families that are struggling with food insecurity.”
That need is seen in research on food screening. The Hunger Vital Signs questions can be asked with a dichotomous variable, as a yes/no question, or on a Likert scale, though the latter is a more complex way to ask.
A 2017 study found, however, that asking with “yes/no” answers missed more than a quarter of at-risk families. In the AAP survey using “yes/no” answers, 31% of families screened positive for being at risk of food insecurity, compared with 46% when the same question was asked on a Likert scale. It seems the ability to answer with “sometimes” feels “safer” than answering “yes,” Dr. Essel said.
Another factor that potentially affects answers is how doctors ask. In a March 2020 study at a single primary care practice, 16% of families screened positive with yes/no responses to a food insecurity screen when the questions were written, compared with 10% of positive screens with verbal responses (P < .001).
Epidemiology of food insecurity
The most updated United States Department of Agriculture report on food insecurity released in September shows the United States finally reached prerecession levels in 2019, with 11% of families designated as “food insecure.” But 2019 data cannot show what has occurred since the pandemic.
Further, the numbers are higher in households with children: Fourteen percent, or one in seven households with children, are experiencing food insecurity. Racial and ethnic disparities in food insecurity have remained consistent over the past 2 decades, with about twice as many Black and Hispanic homes experiencing food insecurity as White homes.
More recent research using Census Household Pulse Surveys has found a tremendous increase in food insecurity for children in 2020. One in three Black children and one in four Hispanic children are food insecure, according to these surveys. The rates are one in six for Asian households and one in ten for White households.
“The disparity is consistent,” Dr. Essel said. “We see what COVID has done. We once may have described it as a great equalizer – everyone is touched in the same way – but the reality is, this is actually a great magnifier. It’s revealing to us and magnifying disparities that have existed for far too long and has really allowed us to see it in a new way.”
A big part of disparities in food insecurity is disparities in wealth, “the safety net or cushion for families when things go wrong,” Dr. Essel said. The median wealth of White Americans in 2016 was $171,000, compared to $20,700 among Latinx Americans and $17,600 among Black Americans, according to the Federal Reserve Board Survey of Consumer Finances.
