Abstract

INTRODUCTION

This report uses data from the 2024 National Health Interview Survey (NHIS) to describe the prevalence of diagnosed seasonal allergies, eczema, and food allergies among adults in the United States, by age, sex, race and Hispanic origin, and urbanization level.

METHODS

Point estimates and the corresponding confidence intervals for this analysis were calculated using SAS-callable SUDAAN software to account for the complex sample design of NHIS. Differences between percentages were evaluated using two-sided significance tests at the 0.05 level. Linear and quadratic trends by age group were evaluated using orthogonal polynomials.

KEY FINDINGS

In 2024, 31.7% of adults had a diagnosed seasonal allergy, diagnosed eczema, or a diagnosed food allergy. The percentage of adults with a diagnosed seasonal allergy was higher among those living in nonmetropolitan areas (28.1%) than those living in metropolitan areas (24.8%). Women (9.5%) were more likely to have diagnosed eczema compared with men (5.7%). The prevalence of these selected allergic conditions varied by age group and race and Hispanic origin.
