Digital Imaging as a Tool for Assessing the Prevalence of Atypical Nevi, Psoriasis and Hand Dermatitis: A Validation Study in Preparation for NHANES IV, Dermatology Section


This validation study is designed to evaluate the sensitivity, specificity, validity and
reliability of digital photography of the skin as a prevalence assessment tool in
preparation for the National Health and Nutrition Examination Survey, 2001 (NHANES IV).
NHANES is charged with monitoring disease in the U.S. population, which is affected
frequently by skin disorders and disease. The three skin disorders proposed for study in
NHANES IV are atypical nevi, psoriasis, and hand dermatitis. This selection is based on the
expected impact of these diseases on the U.S. population, including a prevalence of 3-10%,
associated risk of melanoma in the case of atypical nevi, and associated disability in the
cases of psoriasis and hand dermatitis.

This skin disease section of NHANES, as currently planned for 2001, includes an imaging
component with four standardized photographs to be obtained from each survey participant
(SP). The selection of the regions to be photographed is designed to maximize the
information obtained, while preserving patient privacy and is based on the known
distribution of clinical findings of the three conditions, as well as NHANES logistical
limitations. This validation study is a cooperative effort between the NIAMS extramural
programs, the NCI intramural program, and the National Center for Health Statistics.

Inclusion Criteria


Must have employee status at the National Institutes of Health.

Age greater than 18 years.

Able to understand and sign consent.

Patients who are wheelchair bound and are unable to have images of their back and lower
extremities taken safely will be excluded from photography since this portion of the
examination requires an ability to stand. However, they will still be eligible to
participate in the skin cancer screening.
