A Population-Based Survey of Eczema Prevalence in the United States

Hanifin, Jon M., Reed, Michael L.·2007·Dermatitis

Abstract

BACKGROUND: Eczema and atopic dermatitis (AD) are recognized as major health problems worldwide. Prevalence estimates are as high as one-third of the population, depending on the country studied, the age range of the subjects, and the diagnostic criteria used. National estimates of prevalence for the US population are lacking. OBJECTIVE: To examine the public health problem posed by eczema, AD, and eczematous conditions in the United States by analyzing disease and symptom prevalence, estimating the number of undiagnosed cases, and assessing comorbidities. METHODS: A self-administered questionnaire was sent to a sample of households (N = 60,000) representative of the US population. A designated member responded with information on symptoms, diagnoses, and impact for affected household members; 42,249 households (70%) responded, representing 116,202 individuals. Empirical eczema was defined by itching/scratching and red/inflamed rash or excessive dryness/scaling. Empirical AD was defined by itching/scratching and red/inflamed rash, excessive dryness/scaling, skinfold location, early onset, symptoms lasting or 14 days, or a physician diagnosis of asthma or of allergic rhinitis or hay fever. RESULTS: Of the population studied, 17.1% reported at least one of four eczematous symptoms; empirically defined eczema was found in 10.7%, and empirically defined AD was found in 6%. Prevalence decreased with increasing income. Approximately two-thirds of individuals with an empirical diagnosis of eczema or AD had moderate to severe symptoms, one-third had sleep disturbances, and one-quarter had chronic unremitting symptoms. Just over one-third (37.1%) of those with symptoms reported a physician diagnosis. Peak onset for empirical AD occurred in the group of subjects aged

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
