Abstract 

Objective

To assess whether child food allergy is associated with family food insecurity, overall, and across different income levels.

Methods

We used the 2011-2018 National Health Interview Survey, a nationally representative cross-sectional survey. The exposure was child food allergy, and our main outcome was odds of family food insecurity, which was calculated using multivariable logistic regression models adjusted for child demographics, family characteristics and survey year. We examined for effect modification by the ratio of family income to the poverty threshold using stratification and tests for statistical interaction.

Results

Among 83,287 children 6% had food allergy and 22% experienced family food insecurity. Child food allergy was associated with a 1.39-fold (95% confidence interval [CI]: 1.26, 1.53) increased odds of family food insecurity overall. Child food allergy was associated with a 1.46-fold (95% CI: 1.29, 1.66) increased odds of family food insecurity among children whose families lived below 200% of the federal poverty level, and a 1.26-fold (95% CI: 1.05, 1.51) increased odds of family food insecurity among children whose families lived at 200 to 399% of the federal poverty level, with no association among children whose families lived at or above 400% of the federal poverty level (P =.04 for interaction).

Conclusion

There is an association between child food allergy and family food insecurity, and this association is modified by the ratio of family income to the poverty threshold. Improved availability and subsidy of allergen-free foods in nutrition assistance programs and food pantries are urgently needed.
