National Health Interview Survey (1957–present)
The U.S. government launched the first continuous national health survey in 1957, asking Americans about illness, disability, and healthcare use. It became the country's primary source for national disease prevalence baselines.
Gave public health agencies a consistent national picture of disease burden.
Established the model of recurring national surveillance reports that still shapes U.S. health tracking.
Like NHIS did for disease prevalence broadly, this report gives atopic dermatitis its first national and state-level baseline.
