Pdf Summary

The NCHS Data Brief No. 459 (January 2023) by the CDC's National Center for Health Statistics presents findings on diagnosed allergic conditions among U.S. children aged 0-17 years in 2021. Key points from the 2021 National Health Interview Survey (NHIS) include:<br /><br />- 27.2% of children had at least one diagnosed allergic condition: 18.9% had a seasonal allergy, 10.8% had eczema, and 5.8% had a food allergy.<br />- Boys exhibited a higher prevalence of seasonal allergies (20%) compared to girls (17.7%). The likelihood of seasonal allergies also increased with age: 10.4% (0-5 years), 21.3% (6-11 years), and 24.2% (12-17 years).<br />- Non-Hispanic Black children were more likely to have food allergies (7.6%) and eczema (14.2%) compared to non-Hispanic White and Hispanic children.<br />- The prevalence of eczema varied by age: highest in children 6-11 years (12.1%) and lowest in children 12-17 years (9.8%).<br /><br />This summary highlights that one in four U.S. children had a diagnosed allergic condition in 2021, with the most common being seasonal allergies. There were notable variations based on sex, age, and race/Hispanic origin. For seasonal allergies, boys were affected more than girls, and older children had higher rates. Non-Hispanic Black children had higher rates of food allergies and eczema. Food allergies were somewhat consistent across sex but increased with age.<br /><br />The analysis used data from the NHIS, which conducts interviews throughout the year. Logistic regression was applied to evaluate trends and differences. This brief provides critical insight into the prevalence and demographic disparities of allergic conditions among U.S. children.
